User authentication method and system
First Claim
1. A method of authenticating a user of a security token (11) which has confidential information accessible only in response to a predetermined access code, the method including capturing biometric information of the user, creating a user biometric profile from the captured biometric information, comparing the user biometric profile created from the captured biometric information with a plurality of a biometric profiles contained within a database (24) containing the user biometric profile and other biometric profiles, each biometric profile in the database (24) of biometric profiles having a unique associated code, selecting from the database (24) of biometric profiles the biometric profile corresponding most closely to the user profile created from the captured biometric data, and providing the code associated with the selected biometric profile to the security token (11).

Abstract
A method of authenticating a user of a security token which has confidential information accessible only in response to a predetermined access code, the method including capturing biometric information of the user, creating a user biometric profile from the captured biometric information, comparing the user biometric profile created from the captured biometric information with a plurality of a biometric profiles contained within a database containing the user biometric profile and other biometric profiles, each biometric profile in the database of biometric profiles having a unique associated code, selecting from the database of biometric profiles the biometric profile corresponding most closely to the user profile created from the captured biometric data, and providing the code associated with the selected biometric profile to the security token.
