CA 2457017

The invention relates to a device and method for the recognition of at least one individual and to the corresponding access control device and system and application thereof. The inventive recognition device comprises a one-piece integrated circuit which is produced by integrating the following elements on a silicon substrate: at least one biometric information sensor; means of processing said biometric information; cryptographic means which deliver at least one piece of encrypted data that is representative of at least one part of said biometric information and/or a corresponding piece of recognition information; and protection means that block access to data in transit, stored and/or processed in said one-piece integrated circuit in order to create a secure perimeter. In this way, the data exchanged by said sensor(s), processing means and cryptographic means, and particularly the aforementioned biometric information, are only saved in the one-piece integrated circuit and cannot be accessed from outside. Moreover, only encrypted data are delivered to the outside from said one-piece integrated circuit.

Dispositif et procédé de reconnaissance d'au moins un individu, dispositif et système de contrôle d'accès et application correspondants. L'invention concerne un dispositif de reconnaissance d'au moins un individu, comprenant, dans un circuit intégré monolithique obtenu par l'intégration sur un même substrat de silicium de: au moins un capteur d'informations biométriques, des moyens de traitement desdites informations biométriques, des moyens cryptographiques, délivrant au moins une donnée cryptée représentative d'au moins une partie desdites informations biométriques et/ou d'une information de reconnaissance correspondante, et des moyens de protection, empêchant l'accès aux données transitant, stockées et/ou traitées dans ledit circuit intégré monolithique, pour former un périmètre sécurisé, de façon que les données échangées par le ou lesdits capteurs, lesdits moyens de traitement et lesdits moyens cryptographiques, et notamment lesdites informations biométriques, soient conservées uniquement dans ledit circuit intégré monolithique, restant inaccessibles depuis l'extérieur, et que seules des données cryptées soient délivrées à l'extérieur dudit circuit intégré monolithique.
