In this work the way to increase the security of fingerprints recognition is considered. We suggested the polarimetric technique to be used in recognition systems. The technique was tested on real and model objects. It was demonstrated that the proposed technique allows us to provide effective protection of the system from breaking. Experimental results argue for effectivity of polarimetric techniques against fingerprint spoofing in biometric recognition systems. Based on the polarimetric technique we made a design of polarimetric fiber sensor, which can be used in mobile systems.

This article describes the development of a method for improving the security of fingerprint identification systems. It is based on the calculation of the

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.
