“…Biometric recognition refers to an automatic recognition of individual properties acquired by their anatomic/behavioral characteristics. Several types of biometric techniques have been presented based on these anatomic/behavioral features such as fingerprint, palm print, hand veins, finger veins, palm veins, foot vein, iris, gait, DNA recognition, palates, voice recognition, facial expression, heartbeat, signature, body language, and face shape [2].
