Field of the Invention
[001] The invention relates to payment transactions based on electronic currency tokens. In
particular, the invention provides systems, methods and computer program products for secure
electronic payment transactions based on voice generated currency tokens.
Background
[002] Electronic transactions and payments using payment cards or electronic payment
accounts are increasingly common – with the number of electronic payment transactions and
ubiquity of electronic transaction mechanisms and services growing steadily. Wallet based
payments has also increased significantly in the recent past – such payments offering convenient
options for users to readily transfer payment.
[003] Existing electronic wallets are however heavily dependent on a user being able to
interact with a graphical user interface displayed on a terminal device (for example the display of
a computing device or smartphone) – and on the user being able to conveniently navigate through
the displayed user interface. This poses challenges to users who are unfamiliar with computers or
software interfaces, users who have physical disabilities that prevent them from easily navigating
touch based or key based interfaces, users who are visually impaired and who therefore cannot
navigate interfaces that require sight based abilities, or even users who have their hands full (for
example a user who is driving).
[004] There is accordingly a need for an electronic payment system that provides a simplified
payment interface for electronic payments that addresses the above challenges while
simultaneously meeting the following requirements of electronic payments:
 Security – to prevent fraudulent interference with transactions involving electronic
currency – particularly when such transactions are over public communications
systems such as the Internet
3
 Authentication – to ensure that users of the electronic currency based payment
system can verify, without needing to contact the bank or currency issuer, that the
electronic currency that they receive is valid (i.e. not forged), has not already been
spent, and will be honored by a bank or the currency issuer
 Anonymity – to assure users of the electronic currency that the transactions and
transfers in which they are involved will, if desired remain confidential, in the same
manner as cash transactions
 Transferability – to enable the electronic currency to be transferred to anyone
independent of the type of transaction or transfer, and regardless of the identity of
the concerned transferor and transferee
 Independence – to enable the electronic currency to be spent and received
independent of the physical location of the parties to the transaction
Summary
[005] The invention provides systems, methods and computer program products for secure
electronic payment transactions based on voice generated currency tokens.
[006] The invention provides a method for implementing a voice currency token based
payment system. The method comprises implementing at a voice currency platform server, the
steps of (i) receiving from a payor terminal device (a) a request for generation of a voice currency
token, (b) a payor account ID identifying a payor voice currency platform account associated with
a payor, and (c) voice data comprising information identifying a currency amount to be included
within the requested voice currency token, (ii) performing a first voice based biometric
authentication by matching the voice data received from the payor terminal device against one or
more voice based biometric templates associated with the payor voice currency platform account,
(iii) performing speech analysis to extract at least the currency amount identified within the voice
data received from the payor terminal device, (iv) responsive to the first voice based biometric
authentication generating a positive identity match, generating an encrypted voice currency token.
Generating the encrypted voice currency token comprises (i) generating a voice currency token
data record comprising (a) the payor account ID (b) the currency amount identified within the

Detailed Description
[0041] The present invention is directed towards implementing secure electronic payment
transactions based on voice generated currency tokens.
[0042] For the purposes of the present invention, the following terms shall be understood to
have the corresponding meanings provided below:
[0043] “Payment account” shall mean any account that may be used for the purposes of
effecting an electronic payment or electronic transaction, and shall include any electronic
transaction account, payment card account, bank account or electronic wallet account.
[0044] “Payment network” shall refer to an intermediary between a payor’s bank and a
payee’s bank, which intermediary is authorized by both banks to mediate or effect a payment
transaction between accounts held at each of the two banks. Examples of payment networks
include the Mastercard® or Visa® payment networks. The payment network primarily coordinates
12
payment transactions between acquirers and issuers, and additionally coordinates clearing and
settlement services to transfer payments from issuers to merchants.
[0045] Figure 1 illustrates a system environment 100 that can be used for implementing
electronic transactions based on voice generated currency tokens.
[0046] As illustrated in Figure 1, system environment 100 includes a plurality of users /
individuals / entities or payment account holders 102, 102’ interacting with system environment
100 through their respective terminal devices 104, 104’. The plurality of terminal devices 104, 104’
are configured for network based communication with one or more other entities through network
106.
[0047] Voice currency platform 108 may be communicably coupled with one or more of
terminal devices 104, 104’ (for example through network 106), and comprises voice currency
server 108a, voice currency platform database 108b and voice currency platform interface gateway
108c. Voice currency server 108a may be configured to generate voice based currency tokens,
enable and track transfer of such voice based currency tokens from one individual / entity to
another, and to enable settlement of payment between a payor and a payee upon redemption of
one or more voice based currency tokens.
[0048] In an embodiment, voice currency platform 108 may be implemented within a payment
network that enables payment transactions between individuals / entities or bank accounts
associated with such individuals / entities – for example within any one of the MasterCard®,
VISA®, Discover® or American Express® payment networks. In such embodiments, voice
currency platform 108 may be configured to enable individuals / entities who are authorized to
use the services of the concerned payment network (for example cardholders who have been
issued payment cards or payment accounts associated with the concerned payment network), to
carry out payment transactions over said payment network using the voice currency token
generation and voice currency token redemption capabilities of voice currency platform 108 that
are discussed in more detail below.
[0049] In certain embodiments, voice currency platform enables payment transactions using
voice based currency tokens, only between individuals or entities that are registered with or
authorized to use the services of voice currency platform 108. A determination whether an
13
individual / entity is authorized to use services of voice currency platform 108 may be made based
on information retrieved from voice currency platform database 108b. Voice currency platform
interface gateway 108c may include a hardware or software network gateway configured to enable
voice currency platform 108 to communicate with network 106 and / or other entities within
system environment 100.
[0050] Voice currency platform 108 may additionally be configured for network based
communication with one or more banks 110, 110’ (for example, a payor’s bank and a payee’s bank)
to enable voice currency platform 108 to effect transfer of payments from a payor’s bank account
held with a first bank 110 to a payee’s bank account 110’ held with a second bank.
[0051] In a particular embodiment, voice currency platform 108 may be configured to
interface or communicate with said banks through a payment network for the purposes of
effecting payment transfers between banks (for example through any one of the MasterCard®,
VISA®, Discover® or American Express® payment networks).
[0052] Figure 2 illustrates an embodiment of voice currency platform server 108a, comprising
components 202 to 220. As shown in Figure 2, voice currency platform server 108a includes at
least processor 202, account creation request handler 204, account information database 206,
speech analyzer 208, authentication engine 210, voice currency token encryptor 212, voice
currency token decryptor 214, transaction request handler 216, settlement handler 218 and voice
currency token database 220. The configuration and functionality of the above components is
described in more detail in connection with Figures 3 to 12. In an embodiment, voice currency
platform server 108a may comprise one or more servers implemented within a payment network
that enables payment transactions between individuals / entities or bank accounts associated with
such individuals / entities – for example within any one of the MasterCard®, VISA®, Discover®
or American Express® payment networks.
[0053] Figure 3 comprises a flowchart illustrating a method of creating a user account at voice
currency platform server 108a.
[0054] Step 302 of Figure 3 comprises generating at voice currency platform server 108a, a
user account associated with an individual / entity that has requested creation of said account. In
an embodiment, said user account may be generated in response to a request for creation of an
account being received at account creation request handler 202 – which request may have been
14
transmitted by a terminal device being operated by a requesting individual / entity. The account
creation request handler 204 may interface with processor 202 and generate the requested account
– wherein information corresponding to the generated account may be stored in account
information database 206.
[0055] Step 304 comprises enrolling a payment account that is associated with the requesting
user / entity, with the generated user account. In an embodiment, this step may include storing
information corresponding to the payment account in a data record that has been associated with
the generated user account within account information database 206.
[0056] Step 306 comprises receiving one or more voice sample(s) from the requesting user /
requesting entity, and generating one or more voice sample based biometric templates based on
voice biometric information extracted from the received voice samples. The voice samples may be
recorded by the requesting user / requesting entity at a terminal device having appropriate voice
sample recording capabilities (which in an embodiment may comprise a smartphone or other
mobile communication device having a voice transceiver) and may be transmitted to voice
currency platform server 108a. Voice currency platform server 108a may be configured to analyze
the received voice samples and generate corresponding voice sample based biometric templates
using one or both of processor 202 and speech analyzer 208 operating in accordance with known
methods of voice sampling and voice based biometric template generation.
[0057] At step 308, the generated voice sample based biometric template(s) is associated with
the generated user account, and may in an embodiment be stored in one or more data records
associated with the generated user account, within account information database 206.
[0058] Figure 4A illustrates an exemplary data structure 400A that may be used to store data
records associated with a user account that has been generated in accordance with the method of
Figure 3 (for example, within account information database 206). As shown in Figure 4A, data
structure 400A may include data fields or data records configured to enable storage of one or more
of (i) an account ID used to identify a user account (generated at step 302), (ii) a payment account
ID identifying a payment account that has been enrolled with the user account (at step 304), (iii) a
voice biometric ID identifying one or more voice based biometric templates that have been
associated with the user account (at step 308) – which voice based biometric templates may in
certain embodiments be retrievable from account information database 206 based on the voice
15
biometric ID, and (iv) voice currency token information – comprising one or more of (i)
information identifying one or more voice currency tokens that have either been generated by a
user associated with the user account for transfer to another individual / entity, or which have
been generated by another user for transfer to the individual / entity associated with the user
account and (ii) the voice currency tokens themselves. A detailed explanation regarding said voice
currency tokens and the manner in which they are generated, modified and redeemed is provided
in connection with Figures 5 to 12 hereinbelow.
[0059] Figure 5 is a flowchart illustrating a method for generating voice currency tokens in
accordance with the present invention.
[0060] Step 502 comprises receiving a request for initiating generation of a voice currency
token. Said request may be received at voice currency platform server 108a. In an embodiment,
said request is received from a terminal device being operated by a payor who intends to generate
a voice currency token for effecting an electronic payment to a payee. In a specific embodiment
of the invention, one or both of the payor and the payee are necessarily individuals / entities who
are enrolled with or have user accounts with voice currency platform server 108a (for example
through the method of Figure 3).
[0061] The request for initiating generation of a voice currency token may be received through
an interface provided on the terminal device being operated by the payor. In an embodiment of
the invention, the interface is configured to receive (for example through a voice transceiver or
other audio sensors) voice based instructions from a user of the terminal device – which voice
based instructions may include a voice based instruction for initiating generation of a voice
currency token. In a particular embodiment of the invention, where the instruction for initiating
generation of a voice currency token is a voice based instruction, said voice based instruction is
received by speech analyzer 208 within voice currency platform server 108a. Speech analyzer 208
may be configured to receive voice data, analyze such voice data, extract speech content from the
received voice data, and identify within the extracted speech content any instructions or inputs
that the voice currency platform server 108a has been configured to respond to.
[0062] Step 504 comprises receiving from the payor’s terminal device (i) a payor account ID
identifying a voice currency platform account associated with the payor (the payor’s voice currency
platform account), (ii) a voiced instruction identifying a currency amount to be included within the
16
voice currency token intended for generation, and optionally one or both of (iii) a validity period
for which the voice currency token under generation is intended to be valid / redeemable and (iv)
a payee account ID identifying a voice currency platform account associated with a designated
payee (the designated payee’s voice currency platform account). In an embodiment of the
invention, the information is received by voice currency platform 108a in the form of one or more
voice based inputs from the payor’s terminal device, and the information described hereinabove
is extracted from said voice based inputs by speech analyzer 208.
[0063] It would be understood from step 504 that when generating a voice currency token,
the payor may intend the token to be redeemed by any individual / entity – in which case the
information provided at step 504 may not include information identifying a designated payee’s
voice currency platform account. If on the other hand, the payor intends for the token to be
redeemed by a specific individual / entity, the payor may include information identifying a
designated payee’s voice currency platform account.
[0064] The payor may optionally also choose to specify a validity period within which the
generated voice currency token can be redeemed. If the voice currency token is not redeemed /
submitted for payment, the voice currency token generated based on the information at step 504
may be rendered inactive or invalid. In a specific embodiment of the invention, generation of a
voice currency token results in a hold being placed at the payor’s bank account (the bank account
enrolled by the payor at voice currency platform server 108a) on funds equal to the currency value
of the generated voice currency token. Said hold may be retained on the funds within the payor’s
bank account for the duration of validity of the generated voice currency token, or until the voice
currency token is encashed and the held funds are transferred from the payor’s bank account to a
payee bank account.
[0065] Step 506 comprises confirming the identity of the payor by comparing information
extracted from voice data received from the payor terminal device with one or more voice sample
based biometric templates that have been associated with the payor’s voice currency platform
account. In an embodiment of the invention, the step of analyzing the voice data received from
the payor terminal device and comparing said voice data against stored voice sample based
biometric templates is implemented at authentication engine 210 – which authentication engine
may be configured for voice based biometric comparison and authentication – in accordance with
any one or more voice based biometric techniques known in the art.
17
[0066] Responsive to confirmation of the payor’s identity (i.e. responsive to finding a
biometric match between the voice data received from the payor’s terminal device and the one or
more voice sample based biometric templates that have been associated with the payor’s voice
currency platform account), step 508 comprises generating a voice currency token comprising (i)
the payor’s account ID, (ii) the currency amount associated with the voice currency token, and
optionally one or more of (iii) the token validity period, (iv) a designated payee account ID and (v)
an association between the payor’s account ID and a part or whole of the currency amount
associated with the voice currency token.
[0067] While the respective function of the token validity period and the designated payee
account ID have been discussed above (in connection with step 504), the optional recording of an
association between the payor’s account ID and the currency amount specified by the voice
instruction is intended for use in connection with invention embodiments where the currency
amount associated with a voice currency token can be incremented by a recipient of the voice
currency token (discussed in further detail in connection with Figures 9 to 13). In such cases a
plurality of individuals / entities become respectively responsible for payment of parts of the total
currency amount included within a voice currency token – and recording of associations between
each payor and a corresponding part of the total token currency value enables each payor to be
charged or debited for its respective share of the total token currency value.
[0068] The generated voice currency token may be stored in a data record – a non-limiting
exemplary format for which is illustrated as data record 400B in Figure 4B. In an embodiment, the
generated voice currency token may be stored in voice currency token database 220.
[0069] At step 510, the generated voice currency token is encrypted - using one or more
encryption methods that are known in the art. In an embodiment, encryption may be implemented
by voice currency token encryptor 212 within voice currency platform server 108a. The encryption
ensures that once encrypted, the voice currency token can be decrypted (and data can be
subsequently extracted from such decrypted voice currency token) only by legitimate or authorized
entities (for example, individuals/entities/devices that are enrolled with or authorized by voice
currency platform 108. The generated voice currency token may be stored in voice currency token
database 220.
18
[0070] In an embodiment of the invention, the output of step 510 is a voice currency token
that has been encrypted and / or exported into the format of an audio file that is playable by one
or more media player softwares. In another embodiment, the generated playable audio file is
encoded such that playback of the audio file using a media player does not result in audio
presentation of the content of the generated voice currency token, and instead results in
presentation of any standardized or non-standard audio output. Stated differently, encrypting the
generated voice currency token data record outputs a playable audio file configured such that
playback of the audio file results in presentation of audio output that omits the contents of
information fields within the generated voice currency data record. By hearing the standardized or
non-standard audio output, the listener is only able to ascertain that the received audio file is in
fact a valid voice currency token, but not any other contents thereof.
[0071] Step 512 comprises recording an association between the generated voice currency
token and either or both of the payor’s voice currency platform account and a designated payee’s
voice currency platform account. In an embodiment, said association(s) may be stored in one or
both of account information database 206 and voice currency token database 220. By recording
associations between voice currency tokens and payor / payee voice currency platform accounts,
the voice currency platform 108 eliminates the risk of fake voice currency tokens (i.e. voice
currency tokens that have not been validly generated by voice currency platform 108) being used
to spoof genuine voice currency tokens – since such fake voice currency tokens would not have
been properly associated with a payor account or a payee account at voice currency platform server
108a.
[0072] Step 514 comprises transmitting either or both of the encrypted voice currency token
and confirmation regarding generation of the voice currency token to the payor or to a designated
payee. In an embodiment of the invention, where the payor who has requested generation of a
voice currency token has not specified a designated payee or a designated payee voice currency
platform account, the generated voice currency token (or a corresponding token ID or link to a
location where the voice currency token has been electronically stored) may be electronically
transmitted to the payor – for onward forwarding to any individual / entity that the payor intends.
[0073] In another embodiment, where the payor who has requested generation of a voice
currency token has specified a designated payee or a designated payee voice currency platform
account, confirmation of generation of the voice currency token is forwarded to the payor while
19
simultaneously (i) the generated voice currency token (or a corresponding token ID or link to a
location where the generated voice currency token has been electronically stored) may be
electronically transmitted to the designated payee, or (ii) the generated voice currency token is
associated with the designated payee’s voice currency platform account and confirmation of
generation of the voice currency token and its association with the designated payee’s account may
be forwarded to the payee.
[0074] Figure 6 is a communication flow diagram illustrating an exemplary communication
flow in implementing the method of Figure 5.
[0075] At step 602, payor terminal device 104 transmits a voice currency token generation
request along with information relevant to generation of said request (for example, the information
identified at step 504 of Figure 5) to voice currency platform server 108a. Voice currency platform
server 108a verifies the identity of the initiator of the request and responsive to a positive
identification match, generates the requested voice currency token (in accordance with method
steps 506 to 512 of Figure 5). Thereafter, steps 604 and 606 respectively comprise (i) transmission
of confirmation of generation of the requested voice currency token and / or the generated voice
currency token from voice currency platform server 108a to payor terminal device 104, and /or
(ii) transmission of confirmation of generation of the requested voice currency token and / or the
generated voice currency token from voice currency platform server 108a to the payee terminal
device 104’ (in accordance with step 514 of Figure 5).
[0076] Figure 7 comprises a flowchart illustrating a method for redeeming or encashing voice
currency tokens that have been generated in accordance with the teachings of the present
invention. It would be understood that redeeming or encashing voice currency tokens may involve
two possible events – the first, where a voice currency token specifies a designated payee, and the
second where the voice currency token does not specify a designated payee. Both events are
discussed in the following paragraphs.
[0077] Step 702 comprises receiving from a payee terminal device (i.e. from a terminal device
being operated by an individual / entity seeking to redeem or encash a voice currency token), a
request for encashment of a voice currency token. Said request may be received at a transaction
request handler 216 within voice currency platform server 108a and may include at least
information identifying a payee account ID.
20
[0078] It would be understood that the request of step 702 and other information received
from the payee terminal device may in an embodiment be received by way of voice instructions,
which voice instructions may be analyzed by speech analyzer 208 and from which actionable
instructions or inputs that are required for the method of Figure 7 are extracted by speech analyzer
208.
[0079] Step 704 comprises receiving an encrypted voice currency token that is intended to be
redeemed or encashed by the payee.
[0080] For the purposes of step 704, the encrypted voice currency token may be received at
processor 202 of voice currency platform server 108a in one of several ways. In one, the encrypted
voice currency token that is sought to be redeemed is transmitted to voice currency platform server
108a by a payee terminal device (if such voice currency token has been forwarded to the payee and
is available for transmission at the payee terminal device). In another, a corresponding token ID
or link to a location where the voice currency token has been electronically stored, is transmitted
to voice currency platform server 108a by a payee terminal device (if such token ID or link has
been forwarded to the payee and is available for transmission from the payee terminal device).
[0081] In a specific embodiment of the invention where the voice currency token sought to
be encashed is a voice currency token that specifically identifies a designated payee, the designated
payee may not require to transmit the encrypted voice currency token (or a token ID or link
thereto) that is sought to be redeemed. Instead processor 202 within voice currency platform
server 108a may be configured to retrieve all active or valid voice currency tokens that are
associated with the designated payee’s voice currency platform account, and may respond to
receipt of the payee’s request for encashment of a voice currency token by presenting the
requesting payee with all encrypted voice currency tokens that designate the requesting payee as
the intended payment target, and may request said requesting payee to select one or more of such
encrypted voice currency tokens that the requesting payee intends to encash or redeem. The
selected one or more encrypted voice currency tokens may thereafter be retrieved from voice
currency token database 220.
[0082] Responsive to determining that the received encrypted voice currency token is a valid
voice currency token (for example, by confirming that a defined validity period associated with
21
said encrypted voice currency token has not expired or that the encrypted voice currency token
has not previously been encashed), step 706 comprises decrypting the encrypted voice currency
token and extracting (i) the currency amount specified within the encrypted voice currency token,
(ii) the payor account ID(s) associated with said currency amount, and any payment condition
information (i.e. information identifying conditions in which the voice currency token may or may
not be encashed). Said decryption may be implemented by voice currency token decryptor 214 –
which voice currency token decryptor 214 may in an embodiment be configured to decrypt tokens
that have been previously encrypted by voice currency token encryptor 212.
[0083] Step 708 comprises identifying a payor payment account and a payee payment account
for the voice currency token encashment transaction being implemented. In an embodiment, the
payor payment account may be identified by using the payor account ID(s) extracted at step 706,
to lookup user account information associated with said payor account ID(s) – and to retrieve
information identifying the payment account that has been enrolled by the payor with the voice
currency platform account corresponding to said payor account ID (for example, by retrieving
such data from the data records that have been associated with the payor’s voice currency platform
account and that are stored in account information database 206).
[0084] The payee account may similarly be identified by using the payee account ID(s)
received at step 702 to lookup user account information associated with said payee account ID(s),
and thereafter retrieve information identifying the payment account that has been enrolled by the
payee with the voice currency platform account corresponding to said payee account ID (for
example, by retrieving said data from the data records that have been associated with the payee’s
voice currency platform account and that are stored in account information database 206).
[0085] At step 710, transfer of the identified currency amount (i.e. the currency amount
extracted from the decrypted voice currency token) is initiated from the payor payment account
to the payee payment account. In a particular embodiment, said transfer is initiated by settlement
handler 218 – which may be authorized and configured to communicate with the payor’s bank 110
and payee’s bank 110’ – and to request a transfer of the currency amount from the payor payment
account held with the payor’s bank 110 to the payee payment account held with the payee’s bank
110’. In a specific embodiment, transaction handler 218 may be configured to interface with a
payment network to effect the transfer of the currency amount between the payor payment
account and the payee payment account.
22
[0086] At step 712, responsive to receiving confirmation that the payment transaction has
been concluded, a data record corresponding to the encashed voice currency token may be
modified to indicate that the voice currency token has been encashed and is therefore invalid /
inactive / non-redeemable. Recording the voice currency token as invalid / inactive ensures that
the same voice currency token is not used to debit a payor payment account twice. In an
embodiment, the modified data record may be stored in voice currency token database 220.
[0087] Figure 8 is a communication flow diagram illustrating an exemplary communication
flow for implementing the method of Figure 7.
[0088] At step 802, payee terminal device 104’ transmits a voice currency token encashment
request to voice currency platform server 108a. Voice currency platform server 108a decrypts a
received voice currency token, extracts information of relevance from the decrypted voice
currency token and identifies the payor payment account and the payee payment account (in
accordance with method steps 706 and 708 of Figure 7). Thereafter, step 804 involves transmission
of a request to initiate transfer of the currency amount associated with the decrypted voice
currency token from voice currency platform server 108a to a payment network 110. Payment
network 110 concludes the transfer of the currency amount from the payor account to the payee
account and at step 806 transmits confirmation of the transfer back to voice currency platform
server 108a. Responsive to receiving confirmation that the payment has been concluded, voice
currency platform server 108a marks the encashed voice currency token as inactive / invalid, and
at steps 808 and 810 respectively transmits confirmation of the transfer to payee terminal device
104’ and to payor terminal device 104.
[0089] Figure 9 comprises a flowchart illustrating a method for incrementing the currency
amount within a previously generated voice currency token.
[0090] Step 902 comprises receiving a request for initiating generation of an incremented
voice currency token. Said request may be received at voice currency platform server 108a. In an
embodiment, the request is received from a terminal device being operated by a payor (an
incrementing payor) who intends to increment the currency amount within a previously generated
voice currency token. The incrementing payor may be an individual / entity who is enrolled with
or has a user account with voice currency platform server 108a (for example through the method
of Figure 3). In one embodiment, the previously generated voice currency token being
23
incremented may be a voice currency token that records the incrementing payor as a designated
payee. In another embodiment, the voice currency token may not designate a payee, and the
incrementing payor may have received the voice currency token or a corresponding token ID or a
link to a location where the voice currency token has been electronically stored, through electronic
transmission.
[0091] Step 904 comprises receiving from the incrementing payor’s terminal device (i) an
incrementing payor account ID identifying a voice currency platform account associated with the
incrementing payor (i.e. the incrementing payor’s voice currency platform account), (ii) an input
identifying a previously generated encrypted voice currency token that the incrementing payor
intends to increment, (iii) a voice instruction or other input identifying a currency amount sought
to be added or incremented to the identified previously generated encrypted voice currency token,
and optionally one or both of (iv) a validity period for which the incremented voice currency token
is intended to be valid / redeemable and (v) a payee account ID identifying a voice currency
platform account associated with a designated payee (i.e. the designated payee’s voice currency
platform account) for the post-increment voice currency token. In an embodiment of the
invention, some or all of the above information is received by voice currency platform 108a in the
form of one or more voice based inputs from the incrementing payor’s terminal device, and the
information is extracted from said voice based inputs by speech analyzer 208.
[0092] The incrementing payor may, at step 904, optionally choose to specify a validity period
within which the incremented voice currency token is intended to be redeemed. If the incremented
voice currency token is not redeemed / submitted for encashment within this validity period, said
incremented voice currency token may be rendered inactive or invalid.
[0093] Step 906 comprises confirming the identity of the incrementing payor by comparing
information extracted from voice data received from the incrementing payor terminal device with
one or more voice sample based biometric templates that have been associated with the
incrementing payor’s voice currency platform account. In an embodiment of the invention, the
steps of analyzing the voice data received from the incrementing payor terminal device and of
comparing said voice data against stored voice sample based biometric templates is implemented
at authentication engine 210 within voice currency platform server 108a.
24
[0094] Responsive to confirmation of the incrementing payor’s identity (i.e. responsive to
finding a biometric match between the voice data received from the incrementing payor’s terminal
device and the one or more voice sample based biometric templates that have been associated with
the incrementing payor’s voice currency platform account), step 908 comprises generating an
incremented voice currency token comprising (i) an incremented currency amount having a value
equal to an aggregated value of the currency amount extracted from the previously generated
encrypted voice currency token identified at step 904 and the currency amount that is sought to
be added by the incrementing payor, (ii) an association between a payor’s account ID extracted
from the previously generated encrypted voice currency token received at step 904 and the
currency amount extracted from said previously generated encrypted voice currency token, (iii) an
association between the incrementing payor’s account ID and the currency amount that is sought
to be added by said incrementing payor, and optionally one or both of (iv) a token validity period
associated with the incremented voice currency token, and (v) a designated payee account ID.
[0095] It would be understood that an important feature of the method of incrementing a
voice currency token is recording associations between portions of the total incremented voice
currency amount and the respective payors who are responsible for payment of the total
incremented voice currency amount. By virtue of the recordal of said associations, subsequent to
incrementing of a voice currency token, a first payor who has originally generated a voice currency
token remains responsible for payment of the currency amount originally included within the voice
currency token generated by said original payor, whereas the incrementing payor is responsible for
such part of the incremented currency amount within the incremented voice currency token that
has been added to said incremented voice currency token by the incrementing payor.
[0096] At step 910, the incremented voice currency token is encrypted - using one or more
encryption methodologies that would be available to the skilled person. In an embodiment, the
encryption may be implemented by voice currency token encryptor 212 within voice currency
platform server 108a, and the encrypted incremented voice currency token may be stored in voice
currency token database 220.
[0097] As in the case of the method described in connection with Figure 5, in a preferred
embodiment of the invention, the output of step 910 may comprise an incremented voice currency
token that has been encrypted into the format of an audio file that is playable by one or more
media player softwares. In a more preferred embodiment, the generated playable audio file is
25
encoded such that playback of the audio file using an audio player does not result in audio
presentation of the content of the generate voice currency token to a listener, and instead may
result in presentation of any standardized or non-standard audio output. Stated differently,
encrypting the generated voice currency token data record outputs a playable audio file configured
such that playback of the audio file results in presentation of audio output that omits the contents
of information fields within the generated voice currency data record. By hearing the standardized
or non-standard audio output, the listener is only able to ascertain that the received audio file is in
fact a valid voice currency token but not any other contents thereof.
[0098] Step 912 comprises recording association(s) between the incremented voice currency
token and one or more of the incrementing payor’s voice currency platform account, the original
payor’s (i.e. the payor that generated the previously generated encrypted voice currency token that
has been subsequently incremented) voice currency platform account and a designated payee’s
voice currency platform account. In an embodiment, said association(s) may be stored in one or
both of account information database 206 and voice currency token database 220. By recording
the associations between voice currency tokens and payor / payee voice currency platform
accounts, the voice currency platform 108 eliminates the risk of fake voice currency tokens (i.e.
voice currency tokens that have not been validly generated by voice currency platform 108) or
invalidly incremented voice currency tokens being used to spoof genuine voice currency tokens –
since such fake or invalidly incremented voice currency tokens would not have appropriately
recorded associations with a payor account, incrementing payor account or a payee account at
voice currency platform server 108a.
[0099] Step 914 comprises transmitting either (or both of) the encrypted incremented voice
currency token and confirmation regarding generation of the incremented voice currency token to
the incrementing payor or to a designated payee. In an embodiment of the invention, where the
incrementing payor who has requested incrementing of a voice currency token has not specified a
designated payee or a designated payee voice currency platform account, the generated encrypted
incremented voice currency token (or a corresponding token ID or link to a location where the
encrypted incremented voice currency token has been electronically stored) may be electronically
transmitted to the incrementing payor – for onward forwarding to any individual / entity that the
incrementing payor intends.
26
[00100] In another embodiment, where the incrementing payor who has requested
incrementing of a previously generated encrypted voice currency token has specified a designated
payee or a designated payee voice currency platform account, confirmation of generation of the
incremented voice currency token is forwarded to the incrementing payor while simultaneously (i)
the incremented voice currency token (or a corresponding token ID or link to a location where
the incremented voice currency token has been electronically stored) may be electronically
transmitted to the designated payee, or (ii) the incremented voice currency token is associated with
the designated payee’s voice currency platform account and confirmation of generation of the
incremented voice currency token and its association with the designated payee’s account is
forwarded to the designated payee. In embodiments of the invention where the incremented voice
currency token was not generated for redemption by a specific payee, the incremented voice
currency token or a corresponding token ID or link to the incremented voice currency token may
be forwarded to the incrementing payor, or an incrementing payor terminal device – whereafter,
the incrementing payor can choose to transmit the voice currency token or token ID or link to
token to any individual or entity that the incrementing payor intends to transfer the voice currency
to – for redemption by such transferee individual or entity.
[00101] Figure 10 is a communication flow diagram illustrating an exemplary communication
flow in implementing the method of Figure 9.
[00102] At step 1002, incrementing payor terminal device 104 transmits a incremented voice
currency token generation request along with information relevant to generation of said request
(for example, the information identified at step 904 of Figure 9) to voice currency platform server
108a. Voice currency platform server 108a verifies the identity of the initiator of said request and
responsive to a positive identification, generates the requested incremented voice currency token
(in accordance with method steps 906 to 912 of Figure 9). Thereafter, steps 1004 and 1006
respectively comprise (i) transmission of confirmation of generation of the incremented voice
currency token and / or the generated encrypted incremented voice currency token from voice
currency platform server 108a to incrementing payor terminal device 104 and /or (ii) transmission
of confirmation of generation of the incremented voice currency token and / or the generated
encrypted incremented voice currency token from voice currency platform server 108a to the
payee terminal device 104’ (in accordance with step 914 of Figure 9).
27
[00103] Figure 11 comprises a flowchart illustrating a method for redeeming or encashing
incremented voice currency tokens that have been generated in accordance with the teachings of
the present invention. Redeeming or encashing incremented voice currency tokens may involve
two different possible events – the first, where an incremented voice currency token specifies a
designated payee, and the second where the incremented voice currency token does not specify a
designated payee. Both events are discussed in the following paragraphs.
[00104] Step 1102 comprises receiving from a payee terminal device (i.e. from a terminal device
being operated by an individual / entity seeking to redeem or encash an incremented voice
currency token), a request for encashment of an incremented voice currency token. Said request
may be received at transaction request handler 216 within voice currency platform server 108a and
may include at least information identifying a payee account ID.
[00105] It would be understood that the request of step 1102 and other information received
from the payee terminal device may in an embodiment be received by way of voice instructions,
which voice instructions may be analyzed by speech analyzer 208 and used to extract actionable
instructions or inputs that are required for the method of Figure 11.
[00106] Step 1104 comprises receiving an encrypted incremented voice currency token that is
identified by the payee as being available for redemption or identified as intended to be redeemed
by the payee.
[00107] For the purposes of step 1104, it would be understood that the encrypted incremented
voice currency token may be received at processor 202 of voice currency platform server 108a in
one of several ways. In one, the encrypted incremented voice currency token that is sought to be
redeemed is transmitted to voice currency platform server 108a by a payee terminal device (if such
incremented voice token has been forwarded to the payee and is available for transmission at the
payee terminal device). In another, a corresponding token ID or link to a location where the
encrypted incremented voice currency token has been electronically stored, is transmitted to voice
currency platform server 108a by a payee terminal device (if such token ID or link has been
forwarded to the payee and is available for transmission from the payee terminal device).
[00108] In a specific embodiment of the invention, where the incremented voice currency
token that is sought to be encashed is an incremented voice currency token that specifically
28
identifies a designated payee, the designated payee may not require to transmit the encrypted
incremented voice currency token (or a token ID or link thereto) that is sought to be redeemed.
Instead processor 202 within voice currency platform server 108a would be able to retrieve all
active or valid voice currency tokens (including any incremented voice currency tokens) that are
associated with the designated payee’s voice currency platform account, and may respond to
receipt of a request for encashment of the incremented voice currency token by presenting the
requestor with all voice currency tokens that designate the requestor as the intended payee, and by
requesting identification of one or more of such voice currency tokens that the requestor intends
to encash or redeem. The encrypted voice currency token may thereafter be retrieved from voice
currency token database 220 based on identification by the payee as being the token intended for
encashment or redemption.
[00109] Responsive to determining that the received encrypted incremented voice currency
token is a valid voice currency token (for example, by confirming that a time validity period
associated with said encrypted incremented voice currency token has not expired or that the
encrypted incremented voice currency token has not previously been encashed), step 1106
comprises decrypting the encrypted voice currency token and extracting (i) the aggregated currency
amount specified within the incremented voice currency token, (ii) the plurality of payor account
ID(s) associated with respective portions of the aggregated currency amount, and any payment
condition information (i.e. information identifying conditions in which the incremented voice
currency token may or may not be encashed). Said decryption may be implemented by voice
currency token decryptor 214 – which voice currency token decryptor 214 may in an embodiment
be configured to decrypt tokens that have been previously encrypted by voice currency token
encryptor 212.
[00110] Step 1108 comprises identifying the plurality of payor payment accounts and a payee
payment account respectively associated with the plurality of payor account IDs and the payee
account ID - for the purposes of the token encashment transaction being implemented. In an
embodiment, the plurality of payor payment accounts may be identified by using the payor account
IDs extracted at step 1106 to (i) lookup user account information associated with said payor
account IDs, and (ii) to retrieve information identifying the payment accounts that have been
enrolled by each of the plurality of said payors with the voice currency platform accounts
corresponding to said payor account IDs (for example, by retrieving said data from the data
records that have been associated with each payor’s voice currency platform account and that are
29
stored in account information database 206). The payee account may similarly be identified by
using the payee account ID received at step 1102 to lookup user account information associated
with said payee account IDs, and retrieving information identifying the payment account that has
been enrolled by the payee with the voice currency platform account corresponding to said payee
account ID (for example, by retrieving said data from the data records that have been associated
with the payee’s voice currency platform account and that are stored in account information
database 206).
[00111] At step 1110, transfer of the identified aggregated currency amount (i.e. the currency
amount extracted from the decrypted incremented voice currency token) is initiated from the
identified plurality of payor payment accounts to the payee payment account – wherein the
payment instruction / request to each payor payment account identifies the portion of the
aggregated currency amount required to be transferred by said payor payment account. In a
particular embodiment, said transfer is initiated by settlement handler 218 – which may be
authorized and configured to communicate directly or indirectly with each payor’s bank 110’ and
the payee’s bank 110 – and to request a transfer of the currency amount from each payor’s payment
account held with said payor’s bank 110’ to the payee payment account held with the payee’s bank
110. In a specific embodiment, settlement handler 218 may be configured to interface with a
payment network to effect the transfer of the currency amount between each payor’s payment
account and the payee payment account.
[00112] At step 1112, responsive to receiving confirmation that the payment transaction has
been concluded, a data record corresponding to the encashed incremented voice currency token
may be modified to indicate that the incremented voice currency token has been encashed and is
therefore invalid / inactive. Recording the incremented voice currency token as invalid / inactive
ensures that post-encashment, a voice currency token is not used to debit any of the payors’
payment accounts a second time. In an embodiment, the modified data record may be stored in
voice currency token database 220.
[00113] Figure 12 is a communication flow diagram illustrating an exemplary communication
flow in implementing the method of Figure 11.
[00114] At step 1202, payee terminal device 104’ transmits an incremented voice currency
token redemption request to voice currency platform server 108a. Voice currency platform server
30
108a decrypts the encrypted incremented voice currency token that is sought to be encashed,
extracts information of relevance from the said incremented voice currency token and identifies
the plurality of payor payment accounts corresponding to the plurality of payors associated with
said incremented voice currency token, as well as the payee payment account (in accordance with
method step 1106 and 1108 of Figure 11). Thereafter, step 1204 involves transmission of a request
to initiate transfer of the currency amount associated with the decrypted incremented voice
currency token from voice currency platform server 108a to a payment network 110. Payment
network 110 concludes the transfer of the currency amount from the plurality of payor accounts
to the payee account, and at step 1206 transmits confirmation of such transfer back to voice
currency platform server 108a. Responsive to receiving confirmation that the payment has been
concluded, voice currency platform server 108a marks the encashed incremented voice currency
token as inactive / invalid, and at steps 1208 and 1210 respectively transmits confirmation of the
