Abstract

A system and method for enhancing biometric security utilizing a fingerprint sequence authentication process. The method comprising, during an enrollment period for an electronic transaction system, obtaining a set of fingerprint templates associated with a registering user; storing the fingerprint templates on a memory of the electronic transaction system; determining an verification sequence unique to the registering user, wherein the verification sequence comprises a pattern of entering fingerprint images; and associating the verification sequence with the stored set of fingerprint templates to be used for a subsequent authentication of the registering user.

Claims

1. A method of enhancing biometric security, comprising:

during an enrollment period for an electronic transaction system;

obtaining a first set of fingerprint templates associated with a registering user, wherein the first set of fingerprint templates are generated from a first set of fingerprint images entered by the registering user,

storing the first set of fingerprint templates in a memory of the electronic transaction system,

determining a verification sequence unique to the registering user based on an order in which the first set of fingerprint images are entered by the registering user, wherein at least some of the fingerprint images in the first set of fingerprint images are associated with different fingers of the registering user, and

associating the verification sequence with the stored first set of fingerprint templates to be used for a subsequent authentication of the registering user; and

during a subsequent authentication process for the electronic transaction system;

obtaining a second set of fingerprint templates associated with a party requesting a new transaction, the second set of fingerprint templates generated from a second set of fingerprint images entered by the party requesting the new transaction in a second sequence based on an order in which the second set of finger print images are entered,

retrieving the first set of fingerprint templates associated with the registering user from the memory,

comparing the second set of fingerprint templates according to the second sequence to the first set of fingerprint templates according the verification sequence, and

determining whether there is a match between the verification sequence and the second sequence.

2. The method of claim 1, wherein the first set of fingerprint images are entered by the registering user via a fingerprint scanner.

3. The method of claim 2, wherein the fingerprint scanner used to obtain the first set of fingerprint images is embedded on a smart card, and the first set of fingerprint templates is stored in a memory of the smart card.

4. The method of claim 3 further comprising storing the verification sequence in the memory of the smart card.

5. The method of claim 2, wherein the fingerprint scanner used to obtain the first set of fingerprint images is included in a terminal connected to the transaction system.

6. The method of claim 5, wherein the memory of the transaction system comprises a memory of the terminal connected to the transaction system.

7. A method of authenticating a registered user in an electronic transaction system, comprising:

obtaining a second set of fingerprint templates associated with a party requesting a new transaction via a fingerprint scanner, the second set of fingerprint templates associated with the party generated from a second set of fingerprint images entered by the party in a second sequence;

comparing the second set of fingerprint templates associated with the party to a first set of fingerprint templates associated with a registered user and a verification sequence unique to a registered user, the first set of fingerprint templates generated from a first set of fingerprint images entered by the registered user and the verification sequence determined from an order in which the first set of fingerprint images are entered during an enrollment process, wherein at least some of the fingerprint images in the first set of fingerprint images are associated with different fingers of the registered user; and

determining whether there is a match between the verification sequence and the second sequence.

8. The method of claim 7, wherein the party requests the new transaction using a smart card comprising one or more processing modules and a memory, and the smart card is in communication with the electronic transaction system through a terminal connected to the electronic transaction system.

9. The method of claim 8, wherein the fingerprint scanner is embedded on the smart card.

10. The method of claim 9, wherein the first set of fingerprint templates associated with the registered user is stored on the memory of the smart card.

11. The method of claim 10, wherein the determining step is performed at the terminal.

12. The method of claim 8, wherein the fingerprint scanner is part of the terminal.

13. The method of claim 12, wherein the determining step is performed at the smart card, and the second set of fingerprint images entered by the party in the second sequence are entered via the fingerprint scanner at the terminal.

14. The method of claim 12, wherein the determining step is performed at the terminal, and the method further comprising accessing the memory on the smart card and retrieving the first set of fingerprint templates associated with the registered user.

15. The method of claim 7, wherein the party requests the new transaction using a mobile device connected to the transaction system over a wireless network connection, and the fingerprint scanner is part of the mobile device.

16. The method of claim 15, wherein the first set of fingerprint templates associated with the registered user are stored on a memory of the mobile device.

17. The method of claim 7, wherein the requested new transaction comprises one or more of the following:

a sale or purchase;

a credit or debit transaction;

access to a restricted area within a facility;

access to a computing device;

access to a computer network through an access terminal, wherein the access terminal is a computing device.

18. The method of claim 17, wherein the computing device comprises one or more of the following:

a smartphone, a tablet computer, a laptop, a PC.

19. An electronic transaction system, comprising:

a fingerprint scanner configured to obtain a second set of fingerprint images entered by a party requesting a new transaction-in a second sequence;

a memory for storing a first set of fingerprint templates associated with a registered user and a verification sequence unique to the registered user, the first set of fingerprint templates generated from a plurality of fingerprint images entered by the registered user during an enrollment process, wherein the verification sequence is determined based on an order in which the first set of fingerprint images are entered by the registered user during the enrollment period, wherein at least some of the fingerprint images in the first set of fingerprint images are associated with different fingers of the registered user; and

one or more processing modules communicatively coupled to the memory and the fingerprint scanner and configured to;

generate a second set of fingerprint templates associated with the party from the second set of fingerprint images entered by the party via the fingerprint scanner, compare the second set of fingerprint templates associated with the party and the second sequence to the first set of templates associated with the registered user and the verification sequence, and determine whether there is a match between the verification sequence and the second sequence.
