Biometric technology is becoming more and more applicable along with the rapid development of technologies in computer, photoelectric imaging, and image processing and pattern recognition. Biometrics is the technology to recognize or verify a person’s identity by collecting, analyzing his/her physiological characteristics or behavioral characteristics. Biometrics has brought up a new industry. The global annual output in biometric industry has reached several billion US Dollars and is still growing.
Because the physiological behavioral characteristics of a person are unique, stable, and irreproducible, never lost and never left elsewhere, they are used to accurately recognize and verify a person’s identity. Presently, fingerprint, palm print, iris, voice, face, signature and DNA have been successfully applied as biometrical identification technologies. Among these biometric technologies face identification has many strong points, such as
It is widely used in entrance control, safety verification, public security surveillance and criminal investigation
Face identification technology utilizes facial characteristic. It includes subjects of face detection, face tracing and face matching. Face detection is the discrimination of faces from dynamic and complicated background scene. Face tracing means following the path of those faces detected. And face matching is to identify or verify the identities of faces detected.
As a leader in biometrics, Beijing Hisign Inc. has continuously devoted itself to biometrical research and development, and has developed several successful face identification products.
