In the field of security, access control systems have received more and more attention. Compared with the monitoring system and alarm system, the access control system has obvious advantages, it can actively limit the range of movement of personnel, keep out those intruders with illegal intentions, and ensure the safety of users.


At present, the optical fingerprint access control system is a widely used access control system, when used, only need to put the finger on the fingerprint collector collection window, you can complete the unlocking task, the operation is very convenient.


However, traditional optical fingerprint access control systems often encounter artificial fingerprint films, and optical fingerprint instruments with low recognition capabilities are often difficult to distinguish, which is easy for people to exploit loopholes. This makes people with stronger and stronger security awareness worried, in case the fingerprint is stolen and then made into a fingerprint film, how can the security under the traditional optical fingerprint access control be guaranteed?


The technical defect of traditional optical access control lies in the fact that it collects the surface pattern of fingerprints through simple optical principles. During verification, only the fingerprint image needs to be the same as the original entered fingerprint image to pass smoothly, which leaves a great opportunity for criminals.


The silicone fingerprint sleeve that imitates human skin through silicone and then prints the corresponding fingerprint on it is displayed in the individual database of Taobao sellers, and can be sold up to 1,000 per month. This huge number can't help but make people tremble, the advantages of traditional optical fingerprint access control, let people drill technical loopholes, but become the biggest security risk. This is why people are gradually turning their attention to 3D living fingerprint recognition technology.


The so-called 3D living fingerprint recognition technology is through the theory of capacitive sensing, so that the electronic signal directly captures the dermal fingerprint, because the collection is fingerprint dermis (living) information, so the verification is not affected by the fingerprint epidermis dry and wet, damaged and other conditions. Secondly, it does not recognize the silicone fingerprint sleeve without the dermis layer at all, so that the 3D live fingerprint access control, technically, completely makes up for the shortcomings of traditional optical fingerprint access control, while retaining the advantages of simple and practical fingerprint recognition technology.


Compared with traditional optical fingerprint access control systems, 3D live fingerprint recognition technology can eliminate artificial fingerprints through bio-live sensing. With the increase of people's requirements for security, the 3D live fingerprint access control system with obvious advantages such as high performance and high security has been widely popularized and applied because it meets the needs of families and enterprises with increasing security requirements.


In terms of safety precautions, for the safety of family members and their own life and property, no matter how high vigilance and no amount of consideration can be overdone. The reason why 3D living fingerprint recognition technology can become a trend is that it uses new technology to make up for the shortcomings of traditional technology and meet people's needs.
