  • Patent number: 10599925
    Abstract: A method of detecting attempted fraud against a system recognising the iris of the human eye includes generation of a first image of an iris using first means of image capture in a visible light spectrum, and generation of a second image of said iris using second means of image capture in a near infra-red spectrum. The method also includes determination of at least one characteristic of the first image as a function of respective optical characteristics of pixels of a plurality of pixels of this first image and determination of at least one characteristic of the second image determined as a function of respective luminous intensities of pixels of a plurality of pixels of this second image. As a function of these determined characteristics, a signal representative of suspected detection of attempted fraud is generated.

  • Patent number: 10430652
    Abstract: The invention presents a process for determining a video as being a spoof or a genuine recording of a live biometric characteristic, characterized in that it comprises the steps of: preprocessing (200) the video, determining a liveness score (300) of the video, said determination comprising, for each frame of a plurality of frames (j) of the video: computing a difference between a motion intensity of a current frame and that of each frame of a set of preceding frames to infer a differential motion intensity of the current frame, inferring (330), from the differential motion intensities of the plurality of frames, a motion intensity of the video, comparing (340) said motion intensity to a predetermined threshold, and assigning a liveness score to the video, and determining (400) whether the video is a genuine recording of a biometric characteristic or a spoof.

  • Patent number: 10078782
    Abstract: A method for identifying and/or authenticating an individual by a system including a storage device storing at least one binary code of a reference iris and a binary code of an associated reference mask: acquisition of an image of an eye of the individual, segmentation of the acquired image to isolate a region containing the texture of the iris and determine an associated mask, division of the region and the mask into N2 concentric rings, normalization of the region, determination of a binary iris code IC and a binary code of mask IM matching at least one ring of the iris with a ring of the reference iris to minimize a matching distance between the acquired image and the reference image, computation of the minimized matching distance, identification and/or authentication of the individual if the minimized matching distance is less than a predetermined threshold.

  • Publication number: 20160364611
    Abstract: The present invention relates to a method for identifying and/or authenticating an individual comprising the following steps performed by a system comprising a storage device storing at least one binary code of a reference iris and a binary code of an associated reference mask: acquisition 101 of an image of an eye of the individual, segmentation 102 of the acquired image of the eye so as to isolate a region containing the texture of the iris and determine an associated mask, division 103 of said region containing the iris texture and of said mask into N2 of concentric rings, normalization 104 of said region containing the texture of the iris and of said mask of Cartesian coordinates in polar coordinates, determination 105 of a binary iris code IC of size equal to N2*P*F and a binary code of mask IM associated by application of F Gabor filters to each position of P positions of each ring, matching 106 at least one ring of the iris of the acquired image with a ring of the reference iris so as to minimize a ma
