Ensuring the identity of a user in time : a multi-modal fuzzy approach

This work proposes a fuzzy multimodal technique capable of guaranteeing the desired level of security while keeping under control the high costs typically associated to some biometric authentication devices. Specifically we describe a fuzzy controller choosing within a palette of authentication techniques to continuously check and confirm its trust in the identity of a user

Toward trust-based multi-modal user authentication on the Web : a fuzzy approach

In the last few years authentication has become of paramount importance both on the corporate Intranets and on the global Web. While most approaches focus on the initial authentication and then no further check ensure the identity of the navigating user, in this work we present a fuzzy approach to multi-modal authentication for a trust-based, continuous identity check during Web navigation. The potentiality of such an approach for generating trust-based metadata is also discussed

3D Expressive face model-based tracking algorithm

This paper presents a method for tracking a face on a video sequence, by recovering the full-motion and the expres sion deformation of the face using 3D expressive facial model. From some characteristic face points given on the first frame, an approximated 3D model of the face is re constructed. Using a steepest descent image approach, the algorithm is able to extract simultaneously the parameters related to the face expression and to the 3D posture. The algorithm has been tested on the Kanade-Cohn database [1] and its precision has been compared with a standard multi camera system for the 3D tracking (ELITE2002 System). The results in both cases are good. The proposed approach is part of a facial expression analysis system. Our aim is to detect the facial expressions in situations characterized by a moderate head motion in realistic experimental conditions (illumination from the ceiling, and subjects not in frontal pose)
