Disclosed is a method intended to validate that an element is covered with a true skin and implemented by a validation device including a light source at at least one wavelength, a sensor, an analysis module and a decision-taking module. The method may include: placing a surface of the element in front of the light source and the sensor; illuminating, by the light source, the surface of the element; capturing, by the sensor, for each wavelength, an image of the positioned element that encompasses an illuminated zone of the element directly illuminated by the light beam and a peripheral zone ('the diffusion zone of the element,' which is peripheral to the illuminated zone); analyzing the illuminated zone and the diffusion zone of the captured image; and deciding, by the decision-taking module, whether the element is covered with a true skin according to the results of the analysis.

The present invention concerns a method and device for detecting the orientation of an area (DO) of the body of an individual placed on an apposition area (AP) of a biometric sensor mounting (P) designed to form a first image (I) of the area (DO) of the body by total reflection of radiation on the apposition area (AP), and a second image (I) of the area (DO) of the body from radiation able to pass through the tissues of the body and to be reflected on haemoglobin. The method is characterized in that it comprises The present invention also concerns a biometric sensor and an installation for identifying an individual comprising such a device.

A device for capturing an image representing a print of a part of the body of a person, the capture device may include: a base layer; a reference electrode covering the base layer; electronic capsules fixed in the form of a matrix on the reference electrode, each electronic capsule consisting of a microcapsule filled with a liquid medium and particles with two different colors and opposite electrical charges; a support plate covering the electronic capsules and serving as a support for said part; a camera intended to take an image of the electronic capsules; and an active electrode intended to come into contact with said part and electrically connected to a voltage source delivering a non-zero electrical voltage.

An imaging device includes a transparent prismatic element having two contiguous inlet surfaces separated by a ridge. A lens and an image sensor make it possible to acquire images, each including a reproduction of a first pattern located against one of the inlet surfaces, and a reproduction of a second imaged pattern through the other inlet surface. Such a device can be used in a biometric detection apparatus for detecting both a skin print and the vein distribution of a user. The device can also be used in a reading terminal capable of detecting a skin print and a machine-readable tape.
