Anonymous biometric authentication
First Claim
1. A system for anonymous biometric authentication comprising:
- a biometric acquisition device;
a second biometric of an individual seeking to exercise a privilege, said second biometric image captured by said biometric acquisition device;
a database comprising a plurality of first biometrics relating to said privilege; and
a processor coupled to said biometric acquisition device for receiving said second biometric and coupled to said database for accessing said stored first biometrics, said processor having a comparator for comparing said second biometric to said first biometrics stored in said database, wherein an anonymous biometric authentication of an identity of said individual is based on said comparison of said second captured biometric to said first stored biometric.

Abstract
The use of an anonymous biometric authentication system and method that use biometrics to anonymously authenticate an individual and grant certain privileges based on the anonymous authentication is provided. The system and method permit enrollment of an individual by submission of a first biometric and associated identity documents or credentials to an enrollment authority. The enrollment authority verifies the identity of the identity of the individual submitting the biometric using the credentials which are then returned to the individual or discarded. The first biometric is stored in a database for later retrieval in anonymously authenticating an individual seeking to exercise certain privileges. No other personal identity information is stored along with the biometric during the enrollment process. When an individual later seeks to exercise certain privileges, they must submit a second biometric that is compared to the stored biometrics in the database in order to anonymously authenticate the identity of the individual as having access to such privileges. No other personal information is captured, collected, or solicited during the authentication process. Privileges are granted to an individual based on the comparison of the later captured biometric to the stored biometrics in the database. Alternatively, the anonymous biometric authentication system can be designed to avoid repeat offenders by capturing a biometric of an individual seeking to exercise a privilege and denying the privilege if the captured biometric is matched to a biometric stored in a database containing the biometrics of previous offenders. Preferably, the system and method include capture and storage of a powerful biometric identifier based on the iris of the eye which uniquely identifies the individual that has submitted the biometric. Anonymous biometric authentication allows verification of the identity of an individual seeking certain privileges while at the same time protecting the privacy of personal information about the individual.

1. A system for anonymous biometric authentication comprising:
-
a biometric acquisition device;
a second biometric of an individual seeking to exercise a privilege, said second biometric image captured by said biometric acquisition device;
a database comprising a plurality of first biometrics relating to said privilege; and
a processor coupled to said biometric acquisition device for receiving said second biometric and coupled to said database for accessing said stored first biometrics, said processor having a comparator for comparing said second biometric to said first biometrics stored in said database, wherein an anonymous biometric authentication of an identity of said individual is based on said comparison of said second captured biometric to said first stored biometric. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)

22. A system for anonymous biometric authentication comprising:
-
a biometric enrollment system comprising;
a biometric acquisition device;
a first biometric of an individual seeking to be enrolled, said first biometric captured by said biometric acquisition device;
one or more credentials indicative of an identity of said individual;
an enrollment authority for verifying an identity of said individual seeking enrollment using said one or more identification documents;
a good database for storing said captured first biometric after said identity of said individual seeking enrollment has been verified, wherein said good database stores a plurality of first biometrics of individuals enrolled in said anonymous biometric authentication system and wherein said credentials are not stored in said good database with said first biometric;
a biometric authentication system comprising;
a biometric acquisition device;
a second biometric of an individual seeking to exercise a privilege, said second biometric captured by said biometric acquisition device; and
a processor coupled to said biometric acquisition device for receiving said second biometric and coupled to said good database for accessing said stored first biometrics, said processor comparing said second biometric to said first biometrics stored in said database;
wherein an anonymous authentication of said individual is based on said comparison of said second captured biometric to said first stored biometrics and wherein said privilege is granted based on the result of said anonymous biometric authentication of an identity of said individual. - View Dependent Claims (24, 25, 26, 27, 29, 30, 31, 32, 33, 34)

23. A system for anonymous biometric authentication of an individual for granting of one or more privileges comprising:
-
a first biometric indicative of an identity of an individual;
one or more credentials indicative of said identity of said individual;
a privilege sought to be exercised by said individual;
a first memory for storing said first biometric of said individual once said identity of said individual has been verified using said credentials, said first memory comprising a plurality of first biometrics for all individuals authorized to exercise said privilege;
a second memory for storing a second biometric obtained by a biometric acquisition device from an individual seeking to exercise said privilege; and
a comparator for comparing said second biometric of said second memory with said plurality of first biometrics of said first memory for anonymous biometric authentication of said individuals authorized to exercise said privilege.

28. A method of anonymous biometric authentication of an individual for granting one or more privileges comprising the steps of:
-
submitting a transaction request indicative of a privilege that is sought to be exercised;
capturing a biometric of an individual;
storing said captured biometric in a memory;
comparing said captured biometric to a plurality of enrolled biometrics stored in a database corresponding to said privilege that is being sought to be exercised;
anonymously authenticating an identity of said individual based on said step of comparing said captured biometric to said stored biometrics in said database; and
granting said privilege based on said step of anonymously authenticating said individual.
