Optimum Biometric Authentication Scheme Based on Polar Codes

In this project, we consider a biometric authentication scheme as a beneficial and alternative approach for traditional cryptographic authentication systems. Our goal here is to design the component of a biometric authentication scheme, such that the leakage information about the biometric template and  the related secret key to the person who has access to the stored data is minimized. For this purpose, we model this scheme as two communications systems: namely as an XOR channel and a wiretap channel.
