Abstract

A secure method and device of identification by biometric data in which digital biometric data obtained by a sensor are combined with an identifier of an integrated circuit chip contained in a device common to the sensor.

Claims

1. A secure method of identification by biometric data, including the step of combining digital biometric data obtained by means of a sensor with an identifier of an integrated circuit chip contained in a device common to the sensor, the chip identifier being derived from a physical parameter network.

2. The method of claim 1, wherein said combination is implemented for the storage of reference templates by means of said sensor.

3. The method of claim 1, wherein the comparison of a current biometric image with a reference template is performed after combining the image with said identifier.

4. A portable device for authenticating a user based on biometric data, including:

a digital biometric data sensor;

a physical parameter network specific to an integrated circuit chip of the device;

an element for combining an identifier provided by said network with the digital data provided by said sensor;

an element for storing one or several reference templates of the biometric data; and

an element for comparing a current datum with one of the reference templates.

5. The device of claim 4, wherein at least the physical parameter network and the scrambler are integrated on a same chip.
