Patent attributes
A computer-implemented biometric identity verification method including the steps of storing a database of registered users, including data identifying profile attributes of each registered user and a respective plurality of stored biometric signatures, each stored biometric signature associated with a corresponding one or more of the profile attributes. A predicted biometric signature is derived for a requesting user when it is determined that a period of time has elapsed since the requesting user's stored biometric signature was last updated, by adapting the stored biometric signature based on biometric variances derived from a biometric peer group of registered users with at least one profile attribute in common with the requesting user. The predicted biometric signature is used to verify the identity of the requesting user.
