Biometric features are incorporated in many real world systems for unique identification of humans across the world. The features include face, fingerprints, voice, iris and so on. The reason for adapting this is that biometric features provide globally unique identification to people and the techniques are robust. Efficiency and low error rates are another reason for the popularity of biometric systems. There are issues to be resolved in such systems. For instance for every individual such systems are to store many details like fingerprints, iris, face etc. which causes risk to privacy of individuals.
