Executive Summary

Biometrics are automated methods of identifying a person or verifying the identity of a person based on a Physiological or behavioral characteristic. Physiological characteristics include hand or finger images, facial characteristics and iris recognition. Behavioral characteristics include dynamic signature verification, speaker verification and keystroke dynamics. DNA is unique feature among individuals. DNA provides high security level, long term stability, user acceptance and is intrusive. Combining ElGamal cryptosystem and DNA sequence, a novel biometric authentication scheme is proposed.
