Abstract :
We expose the limitations of existing frameworks designed for the evaluation of audiovisual biometric authentication algorithms. The weakness of a classical audiovisual authentication system is uncovered when confronted to realistic deliberate impostors. A client-dependent audiovisual synchrony measure is used in order to deal with deliberate impostors and three new fusion strategies and their performance against random and deliberate impostors are studied.
