Future wireless communication systems will provide a multiplicity of services for an ever growing number of mobile users. Many of these services will depend on the ability of the system to localize and track users as well as to identify them, guaranteeing both system security and users’ privacy. In such a context, we present an integrated solution for localization, tracking and automatic personal identification for radio-navigation in realistic indoor (i.e. GPS-denied) environments. Actually, the goal is to present a demonstration of our system (composed of some WSN nodes and an innovative wireless biometric badge) which implements an innovative distributed positioning/tracking algorithm, and it is also able to authenticate users via a fingerprint matching, in order to enable them to have access to restricted areas with a high level of security. In fact, the proposed badge follow a full system-on-card approach (i.e. it is provided of an embedded fingerprint scanner and it is able to locally execute the fingerprint matching while communicating to the system only the matching result by means of a secure wireless channel). The distributed localization&tracking algorithm and the wireless biometric badge are the results of R&D activities conducted in the last years by several professors, researchers, and students in the Center of Excellence DEWS at the University of L’ Aquila in Italy, as well as its R&D Spin-Off WEST Aquila S.r.l.
