BIOMETRIC AUTHENTICATION METHOD AND SERVER

摘要

A biometric authentication method. The method comprises receiving biometric authentication data from a user via a communication channel and determining an authentication parameter by comparing the biometric authentication data to stored biometric authentication data. The authentication parameter is compared to first and second thresholds. Based on the result of the comparison it is determined whether to refuse to authenticate the user, to authenticate the user, or to request additional authentication data from the user. An authentication server arranged to implement the method is also disclosed.
