What are the biometrics technologies that unlock the physical code?

- May 24, 2019-


Abstract: What are biometrics technologies? Biometrics technology is the use of computers to make personal identification by using the physiological or behavioral characteristics inherent in the human body. Physiological characteristics are inherently congenital; behavioral characteristics are habitual, mostly acquired. We collectively refer to physiological and behavioral characteristics as biological features. Commonly used biological features include: fingerprints, palm prints, irises, retinas, faces, sounds, handwriting, and the like. Let's take a look at the specific content of biometrics with Xiaobian.

Iris recognition


The structure of the human eye consists of the sclera, iris, pupillary lens, retina and the like. After the iris is formed in the fetal development stage, it will remain unchanged throughout the life course. These characteristics determine the uniqueness of the iris characteristics and also determine the uniqueness of the identity. Therefore, the iris feature of the eye can be used as an identification object for each person.

According to Fujitsu data, the iris recognition error recognition may be 1/1500000, while the Apple TouchID error recognition may be 1/50000, the iris recognition accuracy is up to 30 times that of the current fingerprint scheme, and the iris recognition is non-contact. Recognition, recognition is very convenient and efficient. In addition, iris recognition is unique, stable, non-replicable, and in vivo detection. It has an absolute advantage in comprehensive safety performance, and the safety level is currently the highest.


At present, iris recognition has been widely used in financial, medical, security, security, special industry attendance and access control, industrial control and other fields due to its high accuracy and ease of use. Domestic representatives in the field of iris recognition include Zhongke Hongba, Hongxing Technology, Juhong Optoelectronics, Wuhan Rainbow, and Dahua.
