N2 - Differentiation of living fingers, fake fingers and fingers from dead bodies was investigated using spectral analysis. For this purpose, reflection and transmission spectra in the wavelength region from 400 to 1650 nm were recorded from living volunteers and corpses. In an additional small test series (one living volunteer, three cadavers), time-resolved spectral images were prepared using reflectance (derived from pulse oximetry). The dynamic differences in the curves (including the absorption changes caused by the blanching effect and the pulse) provide initial approaches for the realisation of systems for liveness detection. Significant differences that would be useful for the integration into fingerprint recording systems of methods to defend against forgeries are discussed.
