Abstract: The invention relates to a contactless device (1) for capturing a biometric print, said device comprising a user region (10) and an electronic compartment (20), the user region (10) being suitable for receiving a hand portion of a user according to an orientation vector (V), the electronic compartment (20) comprising lighting means and an image-acquiring device (40), the image-acquiring device (40) being oriented along an optical axis (A1) making a first angle (B1) to the orientation vector (V), the lighting means comprising a light source (31) oriented along a lighting axis (A31) such that the projection (PA31) of said lighting axis (A31) in the plane defined by the orientation vector (V) and the optical axis (A1) makes a second angle (B31) to the orientation vector (V), the first angle (B1) being smaller than or equal to eighty degrees, the second angle (B31) being smaller than or equal to eighty degrees.

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.
