A method for contactlessly capturing a biometric fingerprint of part of a hand of a user in an acquisition volume, the method including successively acquiring at least two two-dimensional images of the part of the hand, involving, between said successive acquisitions, modifying the orientation of an object plane by rotating about a pivot axis, the at least two images comprising imaged points of the part of the hand common to said at least two acquisitions, the object plane being modified as a function of a modification of a given current plane for positioning the part of the hand, corresponding to the average current plane in which said part of the hand is located, for each two-dimensional image acquisition, and merging the acquired two-dimensional images of a surface of the part of the hand that is to be depicted.

Method and system for contactlessly capturing a biometric fingerprint

A device for capturing a biometric print of a user, the user compartment including a frontal opening designed for the passage of part of a hand into said user compartment and a lateral opening allowing the passage of the thumb of the user's hand, the lateral opening extending as far as the frontal opening to form a continuous open space, the lateral opening being delimited in a direction of insertion of the user's hand into the user compartment by a user hand positioning stop.

Ergonomic biometric print capture device

A method for verifying the authenticity of the iris of an eye of a biometric recognition candidate, comprising the step of verifying the flatness of the iris from two images of the iris in different orientations with respect to the image sensor. Optical recognition method and device implementing said method.

Method for biometric recognition from irises

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.
