| 摘要 |
The invention relates to a method and system for acquiring and analysing fingerprints with fraud detection, wherein: an image of a fingerprint of an object (100) is formed; the object is irradiated by means of an energising beam (12); a fluorescence (13) emitted by the object in response to the energising beam is analysed; a validity criterion, established from the analysis of fluorescence and making it possible to discriminate biological tissue from other objects, is verified. According to the invention, a region of interest, capable of characterising the biological tissues, is selected on the fingerprint image, said 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. |
