The Fourth Biometric - Vein Recognition

A reliable biometric system, which is essentially a pattern-recognition that recognizes a person based on physiological or behavioral characteristic [1], is an indispensable element in several areas, including ecommerce(e.g. online banking), various forms of access control security(e.g. PC login), and so on. Nowadays, security has been important for privacy protection and country in many situations, and the biometric technology is becoming the base approach to solve the increasing crime. As the significant advances in computer processing, the automated authentication techniques using various biometric features have become available over the last few decades. Biometric characteristics include fingerprint, face, hand/finger geometry, iris, retina, signature, gait, voice, hand vein, odor or the DNA information [2], while fingerprint, face, iris and signature are considered as traditional ones.
