Checking revocation status of a biometric reference template
First Claim
1. A method for checking a revocation status of a biometric reference template previously generated for an individual, said method comprising:
- computing, by a processor of a computer system, a hash value of the biometric reference template;
said processor creating a reference template revocation object for the biometric reference template, said creating comprising inserting into the reference template revocation object;
(i) a location for checking the revocation status of the biometric reference template and (ii) a unique biometric reference template identifier that uniquely identifies the biometric reference template;
said processor ascertaining the revocation status of the biometric reference template through use of the reference template revocation object; and
said processor returning the ascertained revocation status of the biometric reference template to a relying party that had requested the status of the biometric reference template.

Abstract
A method and system for checking a revocation status of a biometric reference template previously generated for an individual. A hash value of the biometric reference template is computed. A reference template revocation object for the biometric reference template is created, which includes inserting into the reference template revocation object: (i) a location for checking the revocation status of the biometric reference template and (ii) a unique biometric reference template identifier that uniquely identifies the biometric reference template. The revocation status of the biometric reference template is ascertained through use of the reference template revocation object. The ascertained revocation status of the biometric reference template is returned to a relying party that had requested the status of the biometric reference template.
