Abstract

Now-a-days biometric systems have replaced the password or token based authentication system in many fields to improve the security level. However, biometric system is also vulnerable to security threats. Unlike password based system, biometric templates cannot be replaced if lost or compromised. To deal with the issue of the compromised biometric template, template protection schemes evolved to make it possible to replace the biometric template. Cancelable biometric is such a template protection scheme that replaces a biometric template when the stored template is stolen or lost. It is a feature domain transformation where a distorted version of a biometric templates generated and matched in the transformed domain .This paper presents a scheme for cancelable face recognition based on linear minimum mean square error This scheme begins with add noise to the original face and applied LMMSE to the face image to obtain face image with magnified fixed noise pattern.
