Abstract: A device for recognition from biometric characteristics extracted from at least one image of at least one iris of a candidate for recognition, the device having an image sensor with a field covering a capture zone in which at least one of the eyes of the candidate for recognition is intended to be located, and an illumination source of the capture zone, the illumination source emitting incident radiation in a wavelength range adapted to excite iris fluorescence and the sensor being arranged to be sensitive to iris fluorescence. Recognition method using such a device.

Abstract: A method for authentication or identification of an individual, that comprises the implementation by data processing means of a terminal, of the following steps: (a) Obtaining a radiation image and a depth map on each of which appears a biometric feature of said individual; (b) Identification in said depth map of a first region of interest likely to contain said biometric feature as all of the pixels of said depth map associated with a depth value which is within a predetermined range; (c) Selection in said radiation image of a second region of interest corresponding to said first region of interest identified in the depth map; (d) Detection of said biometric feature of the individual in said second region of interest selected of said radiation image; and, (e) Authentication or identification of said individual on the basis of the biometric feature detected.
