Detection of fake biotissue by polarimetric method using Mueller matrices

Abstract

In this paper we consider a new method for improving the security of fingerprint identification systems. It is based on calculating polarimetric parameters using the Mueller matrix. This method was tested on gelatin samples that mimic real tissue with fingerprints. We showed that proposed method can increase the reliability of fingerprint sensors. In conclusion, recommendations on the modification of the laboratory setup and on the improving of the polarimetric technology are given.
