Abstract: The invention relates to a method for recording a fingerprint, with authenticity identification, using a fingerprint recording device which is connected to a data processing instrument and has a prism body with a contact face, an illumination unit for illuminating a finger disposed on the contact face and a first camera sensor for recording a fingerprint image, wherein a spectrometer with a slit-shaped stop running along a first direction for cutting out a slit-shaped region of the light reflected by the finger disposed on the contact face, brings about spectral spread in a second direction which differs from the first and, with a second camera sensor, records a multiplicity of spectra corresponding to a multiplicity of successive pixels, wherein, in the recorded fingerprint image of the first camera sensor, a region corresponding to the region defined by the stop of the spectrometer is cut out and epidermal ridges and troughs situated therebetween are identified in this region and the spatial data thereof is
