Abstract
A method includes receiving a registration input including a first raw biometric template and a user identifier. The first raw biometric template may be representative of unique features of a biometric characteristic of a user associated with the user identifier. The method includes generating a first transformed biometric template by applying a random projection to the first raw biometric template and communicating the first transformed biometric template and the user identifier to an authentication server. The method includes receiving a challenge input including a second raw biometric template and the user identifier. The method includes generating a second transformed biometric template and communicating the second transformed biometric template and the user identifier to the authentication server. The method includes receiving a signal indicative of an authentication decision from the authentication server.
