A fraud detection method for access control via facial recognition, wherein the following are carried out in the region of a zone where the access control is verified for an individual presenting in the region of the zone: a measure of the weight of the individual, at least one weight sensor being provided on the ground for this purpose; an estimation of the weight of the individual by processing by a computer unit of an image acquired of the face of an individual presenting at the access control; a comparison by the computer unit between the estimated weight and the measured weight and wherein the computer unit triggers or not the sending of a fraud detection signal as a function of the result of this comparison.

Detection of fraud for access control via facial recognition

The invention relates to a device for acquisition of images for a biometric system, which includes an optical assembly and at least one imager for acquisition of an image of an object to be analysed presented in front of the assembly at a non-determined distance from the latter. The assembly includes at least one diaphragm with a coded aperture. The optical assembly allows acquisition by the sensor(s) of an image of the object capable of being exploited to deduce therefrom the searched biometric information, and of an image of the object acquired via the coded aperture of the diaphragm. The device also includes a processing unit to determine the distance of the object to be analysed as a function of the image of the object acquired via the coded aperture of the diaphragm.

Optical acquisition device for biometric systems

A device and method, the purpose of which is to secure digital fingerprint reading by sequential optical captures with optimization of the exposures to light. At least one of the illumination and detection parameters is adjusted as a function of the acquisition conditions (physiological condition of the epidermis, exposure to ambient light) owing to the means of control.

Device and method for authentication of a document

A security gate has two walls defining between them a passage through which an individual passes, for each wall, a transparent lighting window extending over at least part of the wall, for at least one of the edges of the lighting window, a light source intended to light the edge and to generate light beams that propagate through the thickness of the lighting window, and for each lighting window, at least one extraction zone provided on the lighting window and intended to transmit the light beams towards the face of the individual passing through the passage, the light beams thus transmitted forming, with respect to the plane of the lighting window from which they emanate, an angle adapted to the geometry of the security gate so as to optimize the lighting of the individual.
