Key factors in the public acceptance of biometric systems are non-intrusiveness, ease of use, and trust. In this paper we propose a biometric identity verification system consisting of a non-intrusive virtual mirror interface, and a face verifier using fractal coding to store the biometric template on a smart-card. The virtual mirror interface assists the user to obtain a frontal face image. The limited memory requirements of the fractal template and processing requirements of fractal decoding enable the implementation of the verification procedure on a smart-card. This set-up facilitates non-intrusive and easy to use biometric verification, and provides trust by adding a visualization to the biometric yes/no decision. Since the system does not require user assistance, it enables secure access over the Internet.
