Biometric Identification Technology and Development Trend of Physiological Characteristics

Abstract

Biometric recognition is an interdisciplinary and comprehensive technology that combines computer technology with optics, acoustics, sensors and biostatistical technology closely, with the help of physiological and behavioral characteristics common to human beings to authenticate the identity of the individual. Physical characteristics are born with innate characteristics, while behavioral characteristics are habitual characteristics formed by long-term accumulation of behavior, most of them have acquired characteristics. Usually, fingerprints, hand, faces, iris, finger vein, DNA, palmprints and retinas are classified as human physiological characteristics.
