Abstract

An embodiment of the present invention provides a method for authenticating an identity of an individual received from an approved entity against a centralized multi-modal biometric database in an anonymous process. The method includes receiving an authentication request from the approved entity. The authentication request includes a personal reference code and a biometric template for a biometric feature of the individual but no private or personal data. The method further includes determining if any record in the database exists that includes a personal reference code which matches the reference code of the authentication request. The record in the database further includes one or more stored biometric templates for each individual. Based on the determination of the match, the method compares the biometric template of the authentication request with the stored biometric template and provides an indication to an approved destination of whether the biometric templates match, thus confirming authentic identity.

Claims

1. A method for enrolling anonymous identity-related information in a biometric database comprising a plurality of biometric templates, the method comprising:

receiving a further biometric template in an enrollment request;

making a determination of whether the received further biometric template matches, to within a predetermined margin of error, at least one of the plurality of biometric templates stored in the database;

storing the received further biometric template in the database based on a result of the determination; and

supplying an indication of a result of the enrollment request.

2. The method of claim 1, further comprising:

receiving a personal reference code; and

storing the received personal reference code in the database based on the result of the determination.

3. The method of claim 2, wherein the storing of the received further biometric template and the received personal reference code further comprises storing the personal reference code and the received further biometric template in a record in the database.

4. The method of claim 1, wherein the database further comprises a plurality of personal reference codes, the method further comprising:

receiving a further personal reference code;

comparing the received further personal reference code against the plurality of personal reference codes; and

storing the received further personal reference code in the database based on the result of the determination and a result of the comparison,

wherein the storing of the received further biometric template is further based on the result of the comparison.

5. The method of claim 1, further comprising:

receiving a courier biometric template; and

making a determination of whether the courier biometric template corresponds to an entity authorized to request enrollments in the database,

wherein the storing is further based on a result of the determination of whether the courier template corresponds to an authorized entity.

6. The method of claim 5, wherein the storing is bypassed if the determination relating to the courier template indicates that the received courier template does not correspond to an entity authorized to request enrollments in the database.

7. The method of claim 1, wherein the database further comprises a set of cumulative enrollments comprising biometric templates of previous enrollments and the making of the determination further comprises comparing the received further biometric template against one or more of the biometric templates stored within the set of cumulative enrollments.

8. The method of claim 7, wherein the making of the determination further comprises:

determining a type of the received further biometric template; and

comparing the received further biometric template against those biometric templates in the set of cumulative enrollments having a type that matches the determined type.

9. The method of claim 7, further comprising receiving an indication of a type of the received further biometric template.

10. The method of claim 9, wherein the making of the determination further comprises comparing the received further biometric template against those biometric templates in the set of cumulative enrollments having a type that matches the received indication.

11. The method of claim 1, wherein the storing further comprises storing an indication of a type of the received further biometric template in the database.

12. The method of claim 11, wherein the storing further comprises storing the received further biometric template and the indication of the type of the received further biometric template in a record in the database.

13. The method of claim 1, wherein the receiving further comprises receiving the further biometric template from an entity and the storing further comprises storing the received further biometric template in a table in the database corresponding to the entity.

14. The method of claim 13, wherein when the determination indicates that the received further biometric template matches, to within the predetermined margin of error, at least one of the plurality of biometric templates stored in the database, the storing is allowed if entities corresponding to the at least one of the plurality of biometric templates permit such storing.

15. The method of claim 1, wherein the storing is bypassed if the determination indicates that the received further biometric template matches, to within the predetermined margin of error, at least one of the plurality of biometric templates stored in the database.

16. The method of claim 1, wherein the biometric template is created from a biometric of an animal other than a human being.

17. The method of claim 1, wherein the biometric template is created from a biometric of a human being.

18. The method of claim 1, wherein the received further biometric template is a universal biometric template, and the making of the determination further comprises comparing the received further biometric template against those biometric templates in the database that are universal biometric templates.

19. The method of claim 1, wherein the supplying of the indication further comprises reporting the result the enrollment request to an approved destination for resolution of any problems or issues associated with a failed enrollment.

20. A method of authenticating an identity of an individual within a database of anonymous records, each comprising at least one biometric template and a personal reference code, the method comprising:

receiving an authentication request from the individual, the authentication request comprising a personal reference code and a biometric template for a biometric feature of the individual;

making a determination of whether any record stored in the database exists comprising a stored personal reference code that matches the personal reference code of the authentication request;

comparing the biometric template of the authentication request with the biometric template of the record based on a result of the determination; and

providing an indication of a result of the comparison.

21. The method of claim 20, wherein the authentication request from the individual is submitted by an entity, the method further comprising determining whether the entity is authorized to submit the authentication request.

22. The method of claim 21, wherein:

the authentication request is submitted by a computer associated with the entity,

the receiving further comprises receiving an identification associated with the computer, and

the determining further comprises comparing the identification against a list of identifications associated with approved submitting computers.

23. The method of claim 21, further comprising receiving a courier biometric template,

wherein the determining further comprises identifying whether the received courier biometric template corresponds to an entity authorized to submit authentication requests, and

wherein the making of the determination is performed if the received courier biometric template corresponds to an authorized entity.

24. The method of claim 23, wherein the making of the determination is bypassed if the received courier biometric template does not correspond to an entity authorized to submit authentication requests.

25. The method of claim 20, wherein the individual is a human being.

26. The method of claim 20, wherein the individual is an animal other than a human being.

27. Computer executable software code stored on a computer-readable tangible medium, the code for:

receiving a biometric template in an enrollment request;

accessing a biometric database comprising a plurality of biometric templates;

making a determination of whether the received biometric template matches, to within a predetermined margin of error, at least one of the plurality of biometric templates stored in the database;

storing the received biometric template in the database based on a result of the determination; and

supplying an indication of a result of the enrollment request.

28. Computer executable software code stored on a computer-readable tangible medium, the code for:

receiving an authentication request from an individual, the authentication request comprising a personal reference code and a biometric template for a biometric feature of the individual;

accessing a database of anonymous records, each record comprising at least one biometric template and a personal reference code;

making a determination of whether any record stored in the database exists comprising a stored personal reference code that matches the personal reference code of the authentication request;

comparing the biometric template of the authentication request with the biometric template of the record based on a result of the determination; and

providing an indication of a result of the comparing.
