Device and method of recognizing at least one individual, the corresponding access control device and system and applications thereof
First Claim
1. Device for recognizing at least one individual, characterized in that the device comprises in a monolithic integrated circuit obtained via an integration on a same silicon substrate of:
- at least one biometric information sensor;
means of processing biometric information;
cryptographic means, transmitting at least one piece of encrypted data representing at least one part of the biometric information and/or one piece of corresponding recognition information; and
means of protection, denying access to flowing data, stored and/or processed in the monolithic integrated circuit, to create a secured perimeter,so that data exchanged by the sensor(s), the means of processing and the cryptographic means, and notably the biometric information, is solely kept in the monolithic integrated circuit, remaining inaccessible from outside of the monolithic integrated circuit, and that only the encrypted data is transmitted to the outside of the monolithic integrated circuit.

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.
