Parameters

Biometric technology is a close combination of computer and high-tech means such as optics, acoustics, biosensors and biostatistics principles, and uses the inherent physiological characteristics of the human body, such as fingerprints, face, iris, etc., and behavioral characteristics to identify personal identity. So, what are the mainstream identification methods of biometrics?

Fingerprint recognition

Because fingerprints have the characteristics of lifelong immutability, low repetition rate and convenience, and the identification of user identity can be realized by comparing the detailed feature points of different fingerprints.

Voiceprint recognition

Voiceprint recognition is a recognition technology developed based on the biological characteristics of human vocalization. The voiceprint map formed by each person's speech is different, and the identity can be identified based on the voice.

Vein identification

The vein recognition technology is to obtain the vein distribution map of the user's finger by means of a vein recognition instrument, extract the characteristic values of the vein distribution map through an algorithm, and then match with the characteristic values stored in the database to realize identity verification.

Iris recognition

The iris is the annular portion located between the black pupil and the white sclera, which contains many detailed features such as interlaced spots, filaments, crypts, etc. The iris is formed in the user's early childhood and will not change.

Face recognition

Face recognition technology is a widely used recognition technology in biometric technology. With the rapid development of face recognition technology, the improvement of recognition degree and the reduction of the cost of recognition equipment, there will be more applications.

In contrast, because fingerprint recognition requires the user to press their finger on the sensor, voiceprint recognition requires the user to speak aloud, iris recognition requires the user to get close to the camera, and vein recognition requires the user to place their finger and palm on the vein recognition device. . The face recognition technology can quickly identify the user only when the user is within the field of view of the camera, making face recognition a user-friendly biometric method.

Before the user performs face recognition, the user will use the face recognition device to use the 3D infrared camera to perform live detection on the user by combining software and hardware to determine whether the collected face is a photo, video or software simulation. The recognition accuracy rate of the recognition technology has reached 99.99%, and the misrecognition rate is one in a million, which can effectively avoid various face forgery.
