What is biometric technology?

The so-called biometric technology is the close combination of high-tech means such as computers and optics, acoustics, biosensors, and biostatistics principles. It utilizes the inherent physiological characteristics of the human body (such as fingerprints, face images, red films, etc.) and behavioral characteristics (such as Handwriting, sound, gait, etc.) for personal identification.

Traditional identification methods include identification items (such as keys, certificates, ATM cards, etc.) and identification knowledge (such as user names and passwords). However, due to the main use of foreign bodies, once identification items and identification information of identity are stolen or forgotten, Its identity is easily impersonated or replaced by others.

Biometrics are more secure, confidential, and convenient than traditional identification methods. Biometrics technology has the advantages of being not easily forgotten, having good anti-counterfeiting performance, being not easy to be forged or stolen, being “carried” with it, and being available anywhere at any time.

Due to the human body's unique and non-replicable uniqueness, the biometric key cannot be copied, stolen, or forgotten. Using biometrics for identity verification is safe, reliable, and accurate. Common passwords, IC cards, barcodes, magnetic cards, or keys have many unfavorable factors such as loss, forgetting, copying, and theft. Therefore, using biological "keys", you do not need to carry a large number of keys, and do not bother to remember or change the password. And system administrators don't have to do anything to forget passwords. Biometric technology products are all realized with the aid of modern computer technology. It is easy to integrate computer and security, monitoring, and management system integration to achieve automated management.

Biometric technology can be widely used in government, military, banking, social welfare protection, e-commerce, and security defense.

For example, a depositor walks into the bank. He has neither a bank card nor a withdrawal password. When he withdraws money from a cash machine, a camera scans the user's eyes and then quickly and accurately. Completed the user identity authentication, completed the business, this is a real shot in a business unit of United States Texas Union Bank. What this department of sales uses is the "iris recognition system" in modern biometric technology. After the September 11th incident in the United States, anti-terrorism activities have become the consensus of all governments. It is very important to strengthen the security and defense of the airport. Weisig's face recognition technology has made great achievements in two airports in the United States. It can pick out a certain face from crowded people and judge whether he is a wanted man.
