Non-intrusive face verification by a virtual mirror interface using fractal codes

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.
