Abstract
Systems and methods for biometric authentication are disclosed. A system comprises a biometric sensor and a processing system configured to: receive, from the biometric sensor, data corresponding to a first attempt to validate an identity of a user; determine that a first score associated with the first attempt satisfies an authentication condition associated with a first biometric template; receive, from the biometric sensor, data corresponding to at least one subsequent attempt to validate the identity of the user, wherein the at least one subsequent attempt is received after the first attempt; determine that a second score associated with the at least one subsequent attempt satisfies the authentication condition; identify, based on the first score and the second score, a trend in the scores associated with attempts that satisfy the authentication condition; and, in response to identifying the trend, request the user to enroll a second biometric template.
