Modular Decomposition of Fingerprint Time Series Captures for the Liveness Check

Aditya Abhyankar and Stephanie Schuckers

Abstract—This work demonstrates a faster approach for liveness detection in fingerprint devices. The physiological phenomenon of perspiration, observed in time-series fingerprint images of live people, is used as a measure to classify `live' fingers from `not live' fingers. Pre-processing involves finding the singularity points using wavelets in the fingerprint images and transforming the information back in the spatial domain to form a spatial domain signal. Wavelet packet sieving is used to tune the modes so as to gain physical significance with reference to the evolving perspiration pattern in `live' fingers. The percentage of energy contribution in the difference modes is used as a measure to differentiate live fingers from others. The proposed algorithm was applied to a data set of approximately 58 live, 50 spoof and 28 cadaver fingerprint images captured at 0 and after 2 sec, from three different types of scanners. An overall classification rate of $93.7 \%$ was achieved across all the three scanners.

Index Terms—fingerprints, spoofing, liveness, wavelet analysis, multiresolution analysis, wavelet packet analysis,empirical mode decomposition, Hilbert transform.
