    Volumetric fingerprint data analysis using optical coherence tomography
    (BIOSIG 2013, 2013) Sousedik, Ctirad; Breithaupt, Ralph; Busch, Christoph
    The increasing usage of fingerprint biometrics as a security technology requires the biometric systems to be resistant against moderate or even high attack potential. To date, state-of-the-art fingerprint sensors can be deceived by using an accurate imitation of the ridge/valley pattern of an enrolled fingerprint that can be produced utilizing low-cost, commonly available materials and techniques. The structure of high-resolution 3D volumetric scans of fingertips, acquired by using the Optical Coherence Tomography (OCT), has been analyzed by this work so that a Presentation Attack Detection method could be developed that would render the artefact production process extremely difficult or even practically impossible.
