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.
