Abstract

A method of authenticating the identity of a user to determine access to a system includes providing a plurality of factor-based data instances corresponding to a user, evaluating the factor-based data instances to determine if the user'"'"'s identity is authenticated, and granting or restricting the user'"'"'s access to the system if the user'"'"'s identity is authenticated. More particularly, the method includes providing a modified data instance based on a second data instance, generating a key based on a first data instance, applying the key to the a modified data instance to generate a recovered data instance, interrogating the recovered data instance against the second data instance to generate an authentication value as a result of a correspondence evaluation, and granting or restricting the user'"'"'s access to the system based at least in part on the validity of the authentication value.

Claims

1. A method of authenticating the identity of a user to determine access to a system, comprising:

providing a plurality of factor-based data instances corresponding to a user;

evaluating the factor-based data instances to determine if the user'"'"'s identity is authenticated;

restricting the user'"'"'s access to the system if the user'"'"'s identity is not authenticated; and

granting the user'"'"'s access to the system if the user'"'"'s identity is authenticated.

2. The method of claim 1, further comprising providing an authentication value, based on the evaluation determination.

3. The method of claim 1, wherein restricting the user'"'"'s access includes denying the user'"'"'s access.

4. The method of claim 1, wherein the factor-based data instances include a knowledge-based data instance.

5. The method of claim 1, wherein the factor-based data instances include a possession-based data instance.

6. The method of claim 1, wherein the factor-based data instances include a biometric-based data instance.

7. A method of authenticating the identity of a user to determine access to a system, comprising:

providing a plurality of factor-based data instances corresponding to a user, including at least one modified data instance based on a second data instance of the plurality of factor-based data instances;

generating a key based on a first data instance of the plurality of factor-based data instances;

applying the key to the at least one modified data instance to generate a recovered data instance;

interrogating the recovered data instance against the second data instance to generate an authentication value as a result of a correspondence evaluation;

restricting the user'"'"'s access to the system based at least in part on an invalid authentication value; and

granting the user'"'"'s access to the system based at least in part on a valid authentication value.

8. The method of claim 7, wherein the authentication value is a first authentication value, the method further comprising combining the first authentication value with at least one other authentication value, to generate a combined authentication value.

9. The method of claim 7, wherein restricting the user'"'"'s access includes denying the user'"'"'s access.

10. The method of claim 7, wherein the factor-based data instances include a knowledge-based data instance.

11. The method of claim 7, wherein the factor-based data instances include a possession-based data instance.

12. The method of claim 7, wherein the factor-based data instances include a biometric-based data instance.

14. The method of claim 13, wherein restricting the user'"'"'s access includes denying the user'"'"'s access.

15. The method of claim 13, wherein the modified version of the biometric-based data instance is a first modified version of the biometric-based data instance, and the biometric value is a second modified version of the biometric-based data instance.

16. The method of claim 15, wherein the biometric value is a cryptographic hash of the biometric-based data instance.

17. The method of claim 13, wherein restricting the user'"'"'s access to the system and granting the user'"'"'s access to the system is based on a modified version of the authentication value.

18. The method of claim 17, wherein the modified version of the authentication value is a cryptographic hash of the authentication value.

20. The method of claim 19, wherein restricting the user'"'"'s access includes denying the user'"'"'s access.

21. The method of claim 19, wherein the biometric value is a modified version of the biometric-based data instance.

22. The method of claim 21, wherein the biometric value is a cryptographic hash of the biometric-based data instance.

23. The method of claim 19, wherein restricting the user'"'"'s access to the system and granting the user'"'"'s access to the system is based on a modified version of the authentication value.

24. The method of claim 23, wherein the modified version of the authentication value is a cryptographic hash of the authentication value.

26. The method of claim 25, wherein restricting the user'"'"'s access includes denying the user'"'"'s access.

27. The method of claim 25, wherein the modified version of the biometric-based data instance is a first modified version of the biometric-based data instance, and the biometric value is a second modified version of the biometric-based data instance.

28. The method of claim 27, wherein the biometric value is a cryptographic hash of the biometric-based data instance.

29. The method of claim 25, wherein restricting the user'"'"'s access to the system and granting the user'"'"'s access to the system is based on a modified version of the authentication value.

30. The method of claim 29, wherein the modified version of the authentication value is a cryptographic hash of the authentication value.

13. A method of authenticating the identity of a user to determine access to a system, comprising:

providing a possession-based data instance, a modified version of the possession-based data instance, a knowledge-based data instance, a biometric-based data instance, and a modified version of the biometric-based data instance;

generating a key based on the knowledge-based data instance;

applying the key to the modified version of the possession-based data instance to generate a first recovered data instance;

interrogating the second recovered data instance against the biometric-based data instance to generate a biometric value as a result of a second correspondence evaluation;

combining the key, the possession value, and the biometric value to form an authentication value;

restricting the user'"'"'s access to the system if the user'"'"'s identity is not authenticated, based at least in part on the authentication value; and

granting the user'"'"'s access to the system if the user'"'"'s identity is authenticated, based at least in part on the authentication value.

19. A method of authenticating the identity of a user to determine access to a system, comprising:
