Patent

CA 2712536

An efficient exchange of messages in a system for authenti-cating access to a base device is facilitated through the selection of a particular biometric template from among a plurality of biometric templates. Rather than transmitting the template to a peripheral device, an indication of a location of the particular biometric template within the plurality of biometric templates is transmitted to the peripheral device. At the peripheral device, once the indication of the location and a biometric candidate are received, the particular biometric template may be located and compared to the biometric candidate. Finally, an indication of a result of the comparing may be transmitted to the base device.

Selon la présente invention, un échange efficace de messages dans un système permettant d'authentifier l'accès à un dispositif de base est facilité par la sélection d'un modèle biométrique particulier parmi une pluralité de modèles biométriques. Au lieu de la transmission du modèle à un dispositif périphérique, c'est une indication de l'emplacement du modèle biométrique particulier choisi parmi la pluralité des modèles biométriques qui est transmise. Lorsque le dispositif périphérique reçoit l'indication de l'emplacement du modèle ainsi qu'un candidat biométrique, le modèle biométrique particulier peut être localisé et comparé au candidat biométrique. Enfin, des données relatives au résultat de la comparaison peuvent être transmises au dispositif de base.
