BACKGROUND
[0002] Background description includes information that may be useful in understanding the
present invention. It is not an admission that any of the information provided herein is prior art or
relevant to the presently claimed invention, or that any publication specifically or implicitly
referenced is prior art.
[0003] Travelling of passengers from one place to another via different modes of transport
like train, airplane, ship, and the like causes spreading of contagious diseases through
microorganisms such as viruses, bacteria, fungi and other germs. There are chances of getting
infected when passenger comes into contact with an infected person during travel or during
exploring places of foreign land. The diseases are dangerous for passenger’s health and some
even causes death leading to loss of life. Therefore, it is necessary to protect from such
microorganisms and stay safe. Investigating passengers after travelling helps in identifying
similar situation so that infected passengers are kept according to quarantine protocols like
isolation, staying at home, and avoiding social gatherings. To investigate manually by interacting
with passengers after coming back to their destinations is quite difficult as many of the
passengers hide their travelling history.
[0004] Hiding travelling history increase chances of infection as contagious disease can
spread and is transmitted. Similar situation prevails during pandemic COVID 19, making it
difficult to trace travelling history of the passengers due to hiding of truth, which increases
infected persons. There is other means to monitor passengers travel history by maintaining
manual records, cross verifying and manual inspecting for travel history. However, such means
are difficult to implement and follow, and there can be high chances of error. Also, sometimes
passenger’s cooperation lacks in such efforts, further making it difficult to monitor and find
travel history.
3
[0005] There is a need to overcome above mentioned problems by bringing solution, which
aids in tracking foreign entity and facilitates in keeping travelling history intelligently. The
solution further reduces the chances where passengers hide the truth related to their travelling
and provide efficient way to deal with above mentioned problem.

set of signals and a fourth set of signals from a first set of signals and a second set of signals
respectively, compare retrieved codes and location history with a data set, where the data set can
include predefined limit ranges, decrypt the retrieved codes when at least one of the retrieved
codes is found within predefined limit ranges, identifies at least one of the foreign entity among
one or more foreign entities based on the decrypted retrieved codes and compared location
history with help of sub units of the processing unit 106.
[0069] In an embodiment, the sub units can include the extraction unit 212 configured to
extract a third set of signals and a fourth set of signals from a first set of signals and a second set
of signals respectively, where the third set of signals can pertain to retrieved codes associated
with the travelling information, and the fourth set of signals can pertain to location history
associated with the one or more foreign entities. In an illustrative embodiment, the extraction
unit 212 can be configured to receive the first set of signals from data acquisition unit 102 and

form by the extraction unit 212.
[0070] In an illustrative embodiment, the extraction unit 212 can facilitate in extracting key
associated with the codes of the travelling information. The key can include predetermined
length of texts, characters, digits, and numbers. The extraction unit 212 can extract the key with
ticket number from the first data set, where the first data set can be stored in a database 210. In
another illustrative embodiment, as the foreign entity enters airport, data acquisition unit 102
such as bar code 102 can be read by a scanning unit such as bar code scanner. The bar code
scanner can read the code with ticket number and can transmit the first set of electrical signals to
the extraction unit 212 to be stored in the first data set. The extraction unit can enable extracting
14
the key or retrieved codes in machine readable form from the first data set of database 210. In yet
another illustrative embodiment, the location and position parameters received from the
positioning unit 104 in form of the second set of electrical signals to the extraction unit 212, can
be extracted as fourth set of signals in machine readable form by the extraction unit 212. The
fourth set of signals can pertain to location history of the foreign entity who has travelled or
visited places.
[0071] In an illustrative embodiment, the location and position parameters can include
foreign entity’s current address, longitude, latitude, past address, and the like. In another
illustrative embodiment, as the foreign entity enters the airport, the positioning unit 104
associated with the device 100, can detect the location and position parameters in form of the
second set of electrical signals and can transmit to the extraction unit 212. The extraction unit
212 can facilitate in extracting the fourth set of signals from the second set of signals in machine
readable form. The extraction unit 212 can extract the location history from a second data set,
where the second data set can be stored in the database 210. The fourth set of signals pertaining
to the location history can be stored in the second data set.
[0072] In an illustrative embodiment, the comparison unit 214 can facilitate in comparing the
extracted retrieved codes and the location history with the first data set and the second data set
respectively, where the first data set and the second data set can pertain to predefined limit
ranges. The comparison unit 214 can receive the extracted retrieved codes and the location
history from the extraction unit 212, and can compare with the first data set and the second data
set respectively stored in database 210. The predefined limit ranges can include threshold values
pertaining to the retrieved codes associated with the travelling information of the foreign entity
and the location history of the foreign entity. The comparison unit 214 can compare the extracted
retrieved codes, and the location history, and can facilitate in finding whether the extracted
retrieved codes and the location history has reached the predefined limit ranges.
[0073] In an illustrative embodiment, the comparison unit 214 can receive the extracted
retrieved codes and the location history in machine readable form. The comparison unit 214 can
facilitate in comparing the received extracted retrieved codes and the location history in machine
readable from with help of a comparator. The comparator can enable comparing the extracted
retrieved codes and the location history with the predefined limit ranges. The comparator can
include an analogue comparator or a digital comparator. The digital comparators can compare
15
the extracted retrieved codes and the location history with the predefined limit ranges. The
digital comparators can facilitate comparison with help of logic gates such as AND, NOT or
NOR gates. The digital comparator can be configured to accept the extracted in the machine
readable form. Further three conditions can be applied for the comparison of the extracted first
set of parameters with the predefined limit ranges.
[0074] In an illustrative embodiment, the three conditions associated with the digital
comparator can include a first condition, which can prevail when the extracted retrieved codes
and the location history are found equal to the predefined limit ranges, a second condition can
prevail when the extracted retrieved codes and the location history are found beyond the
predefined limit ranges, and the third condition can prevail when the extracted retrieved codes
and the location history are found within the predefined limit ranges. The digital comparator can
compare and transmit the compared retrieved codes and the location history to the decryption
unit 216 and the identification unit 218 respectively.
[0075] In an embodiment, the decryption unit 216 can be configured to decrypt the received
retrieved codes from the comparison unit 214 in machine readable form. The decryption unit can
be configured with a security algorithm. The security algorithm can facilitate in keeping the key
in encrypted form and unbreakable for the foreign entity who attempts to break the key by false
means. The security algorithm can enable decrypting the key as required. In another illustrative
embodiment, the decryption unit 216 can be configured to decrypt the retrieved codes when at
least one of the code is found within predefined limit ranges. The predefined limit ranges can be
stored in the first data set of the database 210.
[0076] In an illustrative embodiment, when the foreign entity enters the airport, and the bar
code can be configured to be read by the bar code reader, the code associated with the travelling
information can include ticket number, and the ticket number can further include the key of a
predetermined length of digit. The key can be of four digits of the ticket number and is in
encrypted form. In another illustrative embodiment, the key can be decrypted with help of a
computing device, where the computing device can be operatively coupled with the decryption
unit 216. The decryption unit 216 can receive the decrypted code from the computing device in
machine readable form.
[0077] In an illustrative embodiment, the identification unit 218 can be configured to identify
at least one of the foreign entity among the foreign entities based on the decrypted retrieved
16
codes and compared location history. In another illustrative embodiment, the identification unit
218 can receive the decrypted retrieved codes from the decryption unit 216 and the compared
location history from the comparison unit 214 in machine readable form. In yet another
illustrative embodiment, when the foreign entities enters the airport, and the processing unit 106
can be configured to store the retrieved codes and the location history in the database 210, the
identification unit 218 facilitates in identifying the at least one of the foreign entities among
