Secure Personal Recognition System based on Hashes Keys

Human Identification systems provide increased potential for security. In the absence of robust personal recognition schemes, these systems are vulnerable to the deception of an impostor. The proposed work in this paper is used to explore the merits of the Biometric Encryption approach of verifying identity, protecting privacy and ensuring security like secure access to buildings, computer systems, laptops, cellular phones and ATMs. An efficient and secured technique has been proposed by applying the hashed key on biometric template generated from input test image. The cryptographic key is generated independently and can be updated periodically via a re-enrollment procedure. The ease and protection provided by proposed technique will certainly help to promote widespread use of cryptographic systems. This technique not only outputs high entropy keys, but also conceals the original biometric data such that it is impossible to recover the biometric data even when the stored information in the system is open to an attacker.
