Fingerprint Preprocessing Algorithm With Focuse On Future Liveness Detection

Abstract

The aim of this paper is to introduce the problem of fingerprint liveness detection and propose a method for preprocessing of fingerprints, which will be used for liveness detection. In the first part of this paper the basic problematic of false fingerprints is described. Further in the paper the principle of fingerprint preprocessing is introduced. The last part of this paper presents problematic fingerprint types and how well is the algorithm able deal to with it. The algorithm was tested on the LivDet database.
