What does biometrics consist of?

Yes. Facial recognition.

Facial recognition is a technology that recognizes people's facial features, including standard recognition and thermal imaging technology. Standard** recognition is to record the shape and relative position of the subject's eyes, nose, mouth and other facial features through an ordinary camera, and then convert them into digital signals, and then use a computer for identification. Facial recognition is a common form of identification that is now widely used in the field of public safety.

Fingerprint recognition. Thermal imaging is a technique that produces facial images by analysing the thermal radiation produced by blood in the face. Unlike ** identification, thermal imaging technology does not require a good light source and can be used normally even in dark situations.

At present, common biometric technologies include fingerprints, iris, face, palm prints, veins and other physiological feature recognition technologies and behavioral feature recognition technologies such as gait, handwriting, and voice. Biometric technology has many advantages such as good security, not easy to lose, difficult to counterfeit and easy to carry.

In a single modality, vein recognition technology is also unique and reliable, and the accuracy of identity authorization and identity authentication is particularly high.

Multimodal fusion is an important breakthrough in face recognition and even biometric recognition, which can not only improve the accuracy of recognition through multi-factor, but also improve the scene adaptability and privacy security of biometric technology to a certain extent.

Biometric recognition or biometric authentication is a field of computer science that uses biometrics to identify people and control access. Specifically, it can include face recognition, iris recognition, vein recognition, fingerprint recognition, ......

Now fingerprint recognition can be said to be widely used, there are many people will certify that fingerprint recognition is relatively safe, except that our fingerprints are dirty, fingerprints will be damaged, and others will not have any impact. But we have fooled one of the main problems, fingerprints are low cost, easy to copy, and relatively small risk for work attendance.

The iris recognition technology that is more secure than fingerprint recognition has the characteristics of higher security and is not easy to copy, because it is a unique physiological feature of the human body, such as the unmanned convenience store of Tuoshi Intelligence, which uses face recognition and iris recognition technology.

The use of iris recognition technology in dark environments may be subject to certain restrictions, and the recognition time is long, which is not as convenient and fast as fingerprint recognition. For vein recognition technology, it is also unique and reliable, and the accuracy of identity authorization and identity authentication is particularly high. However, there are limitations in promotion due to the fact that the images of the veins inside the fingers need to be accurately captured by special optical lenses.

Biometrics are identification technologies that rely on the physiological characteristics of the human body to authenticate identity. Because it will not be forgotten, will not be lost, reliability, uniqueness, convenience and convenience, it is widely used in smart phones, smart access control, smart attendance, and smart communities.

1. Biometric recognition technology includes physical characteristics such as fingerprints, veins, palm shape, retina, iris, human body odor, face shape, and even blood vessels, DNA, bones, etc.; Behavioral characteristics such as signature, voice, walking gait, etc. The bio-segment identification system samples the biometrics, extracts their unique features and converts them into numbers**, and further disperses these ** constituent feature templates.

2. Biometric identification technology is mainly through human biometrics for identity authentication, where biometrics usually have unique (different from others), can be measured or can be automatically identified and verified, hereditary or lifelong unchanged and other characteristics.
