In recent years, with the continuous development of science and technology and the continuous explosion in the field of artificial intelligence, biometric technology has reached its peak application and has gradually entered the daily life of the public. The technology has also developed rapidly to a certain extent. In the field of biometric technology, in addition to the well-known fingerprint recognition and face recognition,palmVein recognition is a technology that is unfamiliar to the public，It is also developing steadily and slowly entering the public eye.

palmThe development history of vein recognition

1983Kodak employees J. Rice It was first discovered that infrared imaging of blood vessels on the back of the hand can be used as a basis for identification, and was named " veincheck".

1992in the Department of Bioengineering, Hokkaido University, Japan. K. Shimizu Published articles also believe that infrared imaging of hand blood vessels can be used as a basis for identity recognition. As a result, Japan and South Korea took the lead in researching palm vein recognition technology.

1997year, korean BK System Company releases a commercial product for dorsal hand vein recognition BK-100.

After entering the 21st century, Japan's Hitachi and Fujitsu launched finger vein recognition technology and palm vein recognition technology respectively. Fujitsu successfully applied palm vein recognition technology to Suruga Bank of Japan in July 2004. (Suruga)ATM The identity verification link of self-service teller machines.

As an important technology in the field of biometrics,palmVein recognition has gone through nearly twentymanyYears of continuous development have matured。

What is palm vein recognition?

Palm vein recognition technology is a new generation of biometric identification technology.It identifies the secret biometric information inside the human body - vein information. Compared with the first generation biometric identification (fingerprint, face recognition) that exposes the biological password, the security of vein identification has unique advantages.

The principle of palm vein recognition technology is to use the characteristics of hemoglobin in human blood to absorb near-infrared light to obtain palm vein images, and then use positioning, enhancement, feature extraction, etc. AI The algorithm extracts feature values ​​and compares them with the original template stored in the server to verify personal identity.Perfectly replaces codes, cards, coins, and certificates.
