A biometric encryption using face recognition system for watch list

In recent years, it is necessary to protect individual privacy from unauthenticated persons. This paper presents a biométric encryption using face recognition system to identify known and unsuspected persons in watch list applications. The face recognition system is done by the Eigen face approach by PCA algorithm to simplify the authentication process, then to secure the Eigen faces generate the cryptographic key (RNG) and which key is bind that facial images. The faces are accepted as known or unknown face by after verification with present database.
