Abstract
A method and system for acquiring and analyzing fingerprints with fraud detection in which an image of a fingerprint of an object is formed and the object is irradiated by means of an energizing beam. A fluorescence emitted by the object in response to the energizing beam is analyzed and a validity criterion is established from the analysis of fluorescence and making it possible to discriminate biological tissue from other objects is verified. A region of interest, capable of characterizing the biological tissues is selected on the fingerprint image, where the region of interest defines a useful observation area on the object by correspondence, and the validity criterion is established from measurements of fluorescence intensity relative to the observation area only.
