Fringe projection profilometry based secured fingerprint sensor

Abstract

In this paper, we demonstrate the application of fringe projection profilometry (FPP) for secured 3D biometric fingerprint recognition system. For the extraction of texture as well as high frequency information in a practical biometric system simple Fourier filtering methods have been used. We also address the issue of 2D photo and video attacks, which implies presenting a photograph or video before authentication system to get un-authorize access. Using the developed spoof detection technique, the recognition system becomes more credible and secure, and can be used for different commercial and non-commercial applications. © 2018 IEEE.
