Device and method of recognizing at least one individual, the corresponding access control device and system and applications thereof

Method of recognizing at least one individual, characterized in that the method comprises the following stages, integrally implemented inside a monolithic integrated circuit:

• obtaining biometric information of the individual, with help of at least one sensor integrated into the monolithic integrated circuit;
• processing the biometric information;
• encrypting at least a part of the biometric information and/or a piece of corresponding recognition information;
• transmitting the encrypted data to outside of monolithic integrated circuit,
• 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 the outside, and that only encrypted data is transmitted to the outside of the monolithic integrated circuit.

Access monitoring device comprising means of access authorization or refusal to at least one piece of data, at least one object and/or at least one site, characterized in that the device comprises means for receiving and processing encrypted data provided by at least one device for recognizing at least one individual, the device being comprised 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 the 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.
