[0001]The present invention relates to a system and method for providing secured
remote operations in automobiles. More particularly, the present invention relates to dual level authentication techniques to provide remote authorization in automobiles using a handheld device.
BACKGROUND OF THE INVENTION:
[0002] Automobile industry has shown tremendous advancement in last few decades.
The advancement has been in every niche of technology, be it making engines lighter and faster, improvement in aerodynamics etc. One such area where automobile industry has made tremendous improvement is making automobiles smartly operated using remote keyless entry systems. These systems are designed to permit the owner to operate a vehicle smartly from a distance without using a mechanical key. However, these systems have their own disadvantages i.e. if the smart key gets into the hands of other person who is not an authorized user, he/she may use the same to steal/misuse others vehicle.
[0003] Further advancing on this technology, systems for remotely operating vehicles
using smart phone of a user were introduced. These systems function on the basis principle of sending a secured password/code/PIN from the user mobile to an authentication system installed inside the vehicle. The authentication system then allows or disallows the user access to the vehicle based on authentication. However, these conventional systems suffer various disadvantages such as the password/code/PIN used for authentication are generated by a central system either at the manufacturing end or by a server. Said password/code/PIN is sent to the user device. Further, said password/code/PIN is transmitted to the vehicle having a fixed private key. This private key is matched with the public key received from the user device and access is provided. However, said systems do not allow the password/code/PIN to be changes dynamically, which still does not make the system theft proof. Further, these systems are costly and are not reliable.

[0004] Thus, there exist a need for the system that may be used to remotely operate
vehicle in a more secured manner. Further, there exist a need for the system that may not depend on the manufacturer password/code/PIN, instead is capable of generating dynamic password/code/PIN varying with time to make the system theft proof.

[0033] As shown in figure 1, system 100 comprises a telematic device 102 attached to a
smart key mechatronic locking system 104 that includes features such as electric steering lock and engine immobilization and is placed inside a vehicle 106, wherein the vehicle 106 may be two-wheeler, three-wheeler, four-wheeler or any other like vehicle and shall not be restricted in any sense to any one category of vehicle. The telematic device 102 installed inside the vehicle
7

106 is configured with RF, LF, BLE, GPS and GSM connectivity’s. This allows the telematic device 102 to communicate with one of geo satellite 112 so as to acquire location coordinates of the vehicle. In an exemplary embodiment, the telematic device 102 may depend upon the geo-stationery satellite 112 to receive its location co-ordinates. The telematic device 102 is also equipped with inbuilt facility to communicate with other wireless device such as a user handheld device 108. In an embodiment, the handheld device 108 may include one of smart phone, laptop, personal computer or any like device. In another exemplary embodiment, the user device 108 may also depend upon the geo-stationery satellite 112 to receive its location co-ordinates. The system 100 further includes a PIN access propagation (PAP) server 110 remotely in communication with the telematic device 102 and the user device 108. In an embodiment, the term PIN access propagation (PAP) server 110 and server 110 may be used interchangeably in the specification. Said server 110 plays an important role in providing dual-level authentication mechanism in the system 100. Further, the detailed working of said system is explained in relation with figure 2, discussed in below paragraphs.
[0034] Figure 2 discloses the functionality of system 100 disclosed in figure 1. The
telematic device 102 is configured to generate a time varying code or PIN for secure authentication. In an exemplary embodiment, the telematic device 102 may include a microcontroller (not shown) that may be configured to constantly generate a PIN that varies with time and never repeats itself. In another embodiment, the telematic device 102 is operatively connected to the smart key mechanical system 104 such that when the telematic device 102 gets dual-level authentication clearance, it sends a signal to the smart key mechatronic locking system 104 to be accessed by a user device (not shown). In another embodiment, we assume that the smart key mechatronic locking system 104 is initially in locked condition and cannot be accessed through a user device 108. In an example, the smart key mechatronic locking system 104 may be configured to control various functionalities in the vehicle 106 such as steering lock, door lock, ignition control etc. and shall not be limited to any one functionality. As discussed above the telematic device 102 generates the secured code or PIN and shares the same periodically with the server 110. Now, whenever an authorized user having as user device 108 approaches a vehicle 106 and tries to gain access to the vehicles 106, it sends a PIN request to the server 110. As shown in figure 2 the user device 108 and the server 110 may remain connected to each other though web presence 202. In reply, the server 110 authenticates the PIN request from the user
8

device 108. The authentication includes a predetermined authentication process that may depend on several factors not disclosed explicitly in the specification. This type of authentication in the present specification is referred as the first level authentication. In an exemplary embodiment, the first level of authentication is either through the password and or through special queries posed by the server 110 to the user device108. To make such authentication possible answers, passwords and other form of identification are pre-saved on both sides during registration process when the user is registering for this service as an authentic user. It may be further appreciated that the first level of authentication is just a query/response session between the server and the user device where correct responses to the queries establish authenticity of the user.
[0035] After clearing the first level of authentication, the telematic device 102 shares the
latest code/PIN generated with the user device 108 using the wireless link. The user device 108 then shares this code/PIN with the server 110. After receiving the secured code/PIN from the telematic device 102, via the user device 108, said server 110 attaches geo-location coordinates and unique ID to it and send it back to the telematic device 102 using the wireless link. In an exemplary embodiment, the PAP server 110 is configured to assign location coordinates and unique ID of the vehicle 106 to the PIN to generate modified PIN and share the modified PIN with the telematic device 102. In another exemplary embodiment, it may be noted that the geo-location coordinates and said unique ID relates of the vehicle 106 and may be shared with the server 108 by the telematic device 102 installed inside the vehicle 106 subsequent to sharing the secured PIN. The telematic device 102 now evaluates whether the code or PIN generated by itself is same as the code or PIN shared by user device 108 with the server 110. In case the two are same, the telematic device 102 shares the unique ID and geo-location of user device 108 with the server 110 using at least one of GSM, CDMA, Bluetooth and like technologies. The server 110 now evaluates whether the geo-location and unique ID of the vehicle shared in the previous step matches with the geo-location and unique ID of the user device 108 thus shared. If the two are same, then the PAP server 110 authenticates the same and gives OK signal to the telematic device 102 to give user device 108 access of smart key mechatronic locking system 104 remotely. In a particular embodiment, it may be noted that to make the above authentication possible the user device 108 and the vehicle 106 must share a common or corresponding unique ID.
9

[0036] Figure 3 discloses various steps of method performed by the system 100 of figure
1. The method starts with step 302, where the telematic device 102 generates a code/PIN that varies with time. In step 304, the telematic device 102 sends the code/PIN generated to the server 110 periodically via the wireless communication. Step 306, discloses that whenever the user tries to gain access to the vehicle 106 via the user device 108, it shares an authentication request with the server 110. Server 110, in step 308, performs an authentication process, wherein if the authentication is approved the method moves to next step 310. In step 310, the telematic device 102 shares a code or PIN with the server 110. In particular, the code or PIN is shared with server 110 via the user device 108. In an alternative embodiment, it may be said that the PAP server 110 is configured to receive the PIN generated by the telematic device 102. The server 110 then assigns the geo-location and the unique ID of the vehicle 106, received from telematic device 102, with the code or PIN thus received, in step 312 to generate a modified PIN. In step 314, the server 110, then sends the modified PIN to the telematic device 102. The telematic device 102 then compares or evaluates the PIN generated by itself with the modified PIN shared by the PAP server 110 with the telematic device 102, in step 316. If the two are found to be same, then in step 318 the telematic device 102 transmits the geo-location and the unique ID of the user device 108 to the server 110. In an exemplary embodiment, the telematic device 102 may be configured to attain location co-ordinates and unique ID of the user device 108 via one of Bluetooth, GSM, CDMA and like techniques. The server 110, in step 320, evaluates to confirm whether the geo-location and unique ID received in step 312 matches with the geo-location and unique ID received in step 318, if found matching server 110 gives OK signal to the telematic device 102. The telematic device 102 in return gives access of the vehicle 106 to the user via user device 108.
[0037] Figures 4(a) and 4(b) discuss two different scenarios, in real time, where the
present system can be very advantageous viz-a-viz the conventional systems. In one example, if FOB is stolen the thief will not be able to steal the vehicle 106 since user device 108 is still in possession of the user. In particular, time-varying PIN authorization process as discussed in figure 3, which can only be performed by the user device 108, will prevent the thief from stealing the vehicle 106. In another embodiment, if the FOB is lost and the user needs some emergency access method to enter /start the vehicle 106. In such scenario, user device 108 based PIN method can provide some easy steps for the user using the user device to access the vehicle
10

which when compared to the prevalent tedious methods, where the user needs to operate some complex pattern consisting of ignition key /door operations, is much more safe and secure.
[0038] It may be clear to those skilled in the art, the presently disclosed system and
method may be used either independently or in combination with existing technologies being implemented for providing secured remote authorization of the vehicles using the user device.
[0039] While various aspects and embodiments have been disclosed herein, other aspects
and embodiments will be apparent to those skilled in the art. It may be pertinent to note that various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope being indicated by the following claims.
ADVANTAGES OF THE INVENTION:

authorization system using time varying PIN to provide additional authentication. So, if FOB is stolen the thief will not be able to steal the vehicle since user device-based time-varying PIN authentication will fail.
[0041] In another example, present invention discloses, if the FOB is lost and the user
needs some emergency access method to enter /start the vehicle user device-based PIN method can provide some easy steps for the user with user device to access the vehicle (compared to the prevalent tedious methods where the user needs to operate some complex pattern consisting of ignition key /door operations).
[0042] In yet another embodiment, present invention allows the usage of app-based ride
sharing that facilitates multiple users to access the vehicle in secured manner.
