Abstract

The invention relates to authentication in mobile financial transactions, and more particularly, to systems, devices and methods of employing a location tracking function within a mobile device for the purpose of authenticating a user and a trusted transaction when this mobile device is configured to a mobile point-of-sale (POS) terminal. Authentication is primarily implemented by a secure element integrated within the mobile device based on comparison between captured geo-location data and some known information, such as a retailer address, this user's behavior pattern and shopping habit, that may be derived from the geo-location data. In the secure element, a secure memory stores a plurality of geo-location data from which a secure processor generates information concerning a behavior pattern or a shopping habit of the user. A V/A unit receives a real-time geo-location of the mobile device, and thereby, verifies the user or the trusted transaction according to the generated information.

First claim

We claim:

1. A security system that is included in a mobile device and used to authenticate a user or a trusted transaction made via the mobile device, comprising:
a secure memory that stores a plurality of geo-location data that are recorded and updated using a real-time location tracking function of the mobile device;
a secure processor, coupled to the secure memory, the secure processor generating information about a behavior pattern or a shopping habit of the user based on the plurality of geo-location data, the information is stored in the secure memory and prohibited from being transmitted outside the mobile device; and
a verification/authentication (V/A) unit, coupled to the secure memory and the secure processor, the V/A unit determining a real-time geo-location of the mobile device and accordingly verifying the trusted transaction based on the information about the behavior pattern or the shopping habit of the user.

2. The security system according to claim 1 , wherein the secure element is partitioned from an existing mobile device function module in the mobile device.

3. The security system according to claim 1 , wherein the secure element is a standalone component incorporated into the mobile device.

4. The security system according to claim 1 , wherein the secure element is integrated in a removable memory card or a smart card in the mobile device.

5. The security system according to claim 1 , wherein the secure element integrated in an existing embedded component in the mobile device.

6. The security system according to claim 1 , wherein secure environments are created in the secure element to process sensitive data that comprise account numbers, monetary value, access codes, financial transactions, financial balances, right management, program algorithms, passport information, personal identity, and credit history.

7. The security system according to claim 1 , wherein the plurality of geo-location data are identified with respect to a communication network selected from a cellular network, a radio broadcast network, a television broadcast network, a global positioning system (GPS) network and a Wi-Fi computer network.

8. The security system according to claim 1 , wherein the shopping behavior is extracted based on a history of the user's shopping activities that are associated with geo-locations, time of shopping, credit card used, a price range, and retailer branches at a certain geo-location.

9. An authentication method based on information concerning a behavior pattern or a shopping habit of a user, comprising the steps of:
recording a plurality of geo-location data of a mobile device using its real-time location tracking function into a secure memory of the mobile device;
generating and updating the information concerning the behavior pattern or the shopping habit based on the plurality of geo-location data by use of a secure processor of the mobile device;
storing the information concerning the behavior pattern or the shopping habit in the secure memory and prohibiting the information from being transmitted outside the mobile device;
receiving a request from the user to make a trusted transaction; and
verifying, by use of a verification/authentication (V/A) unit of the mobile device, the trusted transaction according to the information concerning the behavior pattern or the shopping habit and a real-time geo-location that is associated with the trusted transaction.

10. The authentication method according to claim 9 , wherein the behavior pattern includes a frequency and a physical range of the user's daily activity.

11. The authentication method according to claim 9 , wherein the shopping behavior is extracted based on a history of the user's shopping activities that are associated with geo-locations, time of shopping, credit card used, a price range, and retailer branches at a certain geo-location.

12. The authentication method according to claim 11 , wherein the trusted transaction is verified according to the shopping habit by a degree of consistency between the trusted transaction and the user's shopping habit.

13. The authentication method according to claim 9 , wherein the step of verifying the trusted transaction is implemented remotely within a remote server.

14. The authentication method according to claim 9 , wherein the step of verifying the trusted transaction is implemented locally within the mobile device.

15. The authentication method according to claim 9 , wherein the authentication method is implemented in hardware, firmware, software or a combination thereof.

16. The authentication method according to claim 9 , wherein the plurality of geo-location data are identified with respect to a communication network selected from a cellular network, a radio broadcast network, a television broadcast network, a global positioning system (GPS) network and Wi-Fi networks.

17. An authentication method based on a geo-location of a mobile device, comprising the steps of:
storing a plurality of geo-location data in a secure memory of a mobile device using a real-time location tracking function of the mobile device;
prohibiting the plurality of geo-location data from being transmitted outside the mobile device;
determining the geo-location of the mobile device using the real-time location tracking function, when a user makes a request for a trusted transaction via the mobile device;
extracting from the plurality of geo-location data, by use of a secure processor of the mobile device, a location of a retailer involved in the trusted transaction;
comparing the geo-location of the mobile device and the location of the retailer; and
authenticating, by use of a verification/authentication (V/A) unit of the mobile device, the trusted transaction when these two locations are consistent.

18. The authentication method according to claim 17 , wherein the step of verifying the trusted transaction is implemented remotely within a remote server.

19. The authentication method according to claim 17 , wherein the step of verifying the trusted transaction is implemented locally within the mobile device.

20. The authentication method according to claim 17 , wherein the authentication method is implemented in hardware, firmware, software or a combination thereof.
