Method and device for automatic capture of a fingerprint with recognition of authenticity.

Method for the automatic capture of a fingerprint with a capture unit fingerprint connected to a processing apparatus based data camera, with a bearing surface and recognition of authenticity of the finger positioned on the capture unit fingerprint, wherein for recognizing authenticity many reflection measurements on a large predetermined number of intervals wavelengths of reflection takes place, the unit having capture fingerprint based camera a photo sensor (10) arranged such that a light reflected by a finger on the support surface which is formed by the surface of a prismatic body (2), characterized in that it captures at least one measurement is captured transmission in a predetermined wavelength range supported wave finger and checked for authenticity conjunction with Measurings tions of reflection which are characteristic for the oxidized blood, to ascertain through these authenticity criteria authenticity supported finger, performing measurement transmission making light is radiated on a region of the finger that is beyond the support surface at its end opposite the support surface through a glass body (6) spaced side, and being captured by the camera the light leaving the support surface sensor (10).
