Biometric authentication system
First Claim
1. A biometric authentication system configured to enable an authentication process, the process having predefined parameters associated therewith, the process providing for authentication of a user based on a comparison of a presented biometric with at least one previously stored biometric, said authentication system comprising:
- 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, said authentication system being configured to authenticate the user on determining that a parameter based on the output score, meets a threshold score; and
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 being provided based on an analysis of the performance of said authentication system over a predefined time period using current threshold scores.

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.

20. A distributed network of authentication systems, at least one of said authentication systems being configured to enable an authentication process, the process having predefined parameters associated therewith, the process providing for authentication of a user based on a comparison of a presented biometric with at least one previously stored biometric, said at least one authentication system comprising:
-
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, said at least one authentication system being configured to authenticate the user on determining that a parameter based on the output score, meets a threshold score; and 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 being provided based on an analysis of the performance of said at least one authentication system over a predefined time period using current threshold scores, wherein said network comprises at least one audit module configured to receive data relating to the authentication process from at least one of said authentication systems within said network, process the received data so as to provide an analysis of the performance of said at least one of said authentication systems using current threshold scores, and generate at least one revised threshold score to supplement the current threshold scores used at one or more of said authentication systems within said network. - View Dependent Claims (21, 22, 23)

24. A method of authenticating a user based on a biometric sample presented by the user, said method comprising:
-
receiving a request for authentication, the request for authentication including a presented biometric; analyzing specifics of the request so as to extract at least one parameter specific to the request; matching the presented biometric with a previously stored biometric for the user so as to provide a matching score; comparing a stored threshold score with the matching score; authenticating the user on determining that the matching score exceeds the stored threshold score; and monitoring the performance of an authentication process over time and updating the stored threshold score with a revised threshold score on determining that the performance of the authentication process using the stored threshold score falls below a desired performance criteria, wherein said updating operation is performed using a computer. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32, 33, 34)
