Abstract

A system and method for authentication a user'"'"'s identity via biometrics is disclosed. The system includes client software, an authentication server, and an independent biometric services server. Data associated with the biometric samples provided by a user are stored in the biometric services server and the user is assigned a unique identifier. The authentication server stores biometric templates consisting of information regarding the biometric samples and type of samples, e.g. voice, retina scans, fingerprints, DNA, etc. The authentication server also stores at least one pointer to the biometrics services server providing a link between the biometric samples stored in the biometric services server and the user'"'"'s biometric template(s). Identity authentication is accomplished by a series of steps including querying the user for an identifier and analyzing a biometric sample provided by the user with the biometric samples stored in the biometric services server. Once the user has been authenticated, a service provider can then securely provide services to and exchange information with the user. A system and method for enrolling a user into the biometric authentication system is also disclosed.
