Abstract
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.
