| titleOfInvention | Method and device for capture of a fingerprint with authenticity recognition |
| abstract | The invention relates to a method for recording a fingerprint with authenticity detection, using a fingerprint recording unit connected to a data processing device, which has a prism body (2) with a bearing surface, a lighting unit (3, 3 ') for illuminating a finger (1 ) and a first camera sensor (6) for fingerprint recording, characterized in that a spectrometer with a slit - shaped aperture (9) running along a first direction for masking out a slit - shaped area of the light reflected from the finger resting on the support surface has a spectral fan - out second, caused by the first different direction and with a second camera sensor (13) a plurality of spectra corresponding to a plurality of successive picture elements, receives that in the recorded fingerprint image of the first camera sensor (6) a through the Aperture of the spectrometer defined area corresponding area is hidden and identified in this area skin strips and intervening valleys and their location data are determined that from the plurality of spectra based on the location data of bars and valleys from the fingerprint image those spectra, according to their location data in the fingerprint image are summarized to a bar, and the spectra, which lie in the fingerprint image in valleys according to their location data, are combined into a valley spectrum, normalized the bar spectrum and the valley spectrum to the same total intensity and these are subtracted from each other to form a differential spectrum, and that the difference spectrum is examined for features for the presence of exogenous coating materials and in whose presence the authenticity is denied. |
