Abstract :
Proposed is a technique for fingerprint spoof detection, the spatial surface coarseness analysis. This approach improves the wavelet analysis of the fingertip surface texture by introducing spatial features to the model. Thus, the accuracy of the fingerprint classification is increased to 70.09% compared with the original solution.
