Abstract
A method of authenticating a user in dependence upon biometric input information is disclosed. According to the method when a user is identified, their biometric information or data derived therefrom is automatically stored. The data is then used in subsequent user identification attempts as a template. The original templates are not replaced but those templates that are automatically stored are replaced at intervals.
