The biometric based crypto techniques extract the features from grayscale images and use those features in encryption process i.e., key will be generated from extracted features. In attribute based crypto-systems attributes of the user like email, usernames etc.…will be treated as a public key. Secret key is associated with each attribute i.e. for email there will be a secret key and for username there will be another secret key. In biometric based crypto systems, an access policy is built from the extracted biometric features.
