Abstract: The invention relates to a method for determining whether or not a papillary imprint consists of living human tissue, using a papillary imprint sensor (110) comprising, superposed, a contact surface (106), an optical matrix sensor (112), and lighting means (111) formed by a plurality of mutually parallel lighting devices (1110). The method according to the invention comprises the following steps: - illuminating the papillary imprint by the lighting means, the lighting devices together forming, on the contact surface, at least one uniform lighting figure along an axis which extends on both sides of a detection surface of the optical matrix detector, and acquiring an image by means of the optical matrix sensor, said steps being implemented at least once; - in each image, selecting pixels corresponding to the valleys of the imprint, or selecting pixels corresponding to the ridges of the imprint; and - from the selected pixels, extracting an optical feature defining the response to at least one illumination, of the material constituting the papillary imprint, and using said optical feature for determining the values of at least two characteristic optical coefficients of the imprint. An imprint can thus be characterised anywhere on the surface thereof.

Abstract: Methods and Apparatuses are provided for a thin high contrast optical acquisition system for fingerprint recognition. In one embodiment, a method of capturing images of a fingerprint may include emitting light from a set of light sources to generate a scattered light from the fingerprint, determining a set of sensor arrays located between an inner boundary and an outer boundary from the set of light sources based on thickness and refractive index of one or more panels between the set of light sources and the fingerprint, activating the set of sensor arrays to capture the scattered light from the fingerprint, and processing the scattered light captured by the set of sensor arrays in parallel to generate a topography of the fingerprint.
