ABSTRACT:
A biometric authentication system configured to enable an authentication process has predefined parameters associated therewith and provides for authentication of a user based on a comparison of a presented biometric with at least one previously stored biometric. The authentication system includes a matching system providing as an output an output score based on the comparison of the presented biometric and the at least one previously stored biometric. Moreover the authentication system is configured to authenticate the user on determining that a parameter based on the output score, meets a threshold score, and includes an audit module configured to monitor the authentication process and to provide at least one revised threshold score. The at least one revised threshold score is provided based on an analysis of the performance of the authentication system over a predefined time period using current threshold scores.
