In the security field, access control systems are receiving more and more attention. Compared with the monitoring system and the alarm system, the access control system has obvious advantages. It can actively limit the scope of action of the personnel, and shut down those who have unintentional attempts to protect the safety of the users.
At present, the optical fingerprint access control system is a widely used access control system. When used, the finger can be placed on the collection window of the fingerprint collection device to complete the unlocking task, which is very convenient to operate.
However, traditional optical fingerprint access control systems often encounter artificial fingerprints, and optical fingerprinting instruments with low recognition capabilities are often difficult to distinguish and are prone to emptiness. This makes people who are more and more aware of security feel worried. If 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 the traditional optical access control is that it collects the surface pattern of the fingerprint through a simple optical principle. When verifying, only the fingerprint image can be passed smoothly with the original fingerprint image, which leaves a great opportunity for the criminals.
The silicone fingerprint sleeve that is imitation of the human skin through silica gel and then printed with the corresponding fingerprint is displayed in a single database of Taobao sellers, and the maximum number of monthly sales is 1,000. This huge number can not help but make people tremble. The advantages of traditional optical fingerprint access control make people drill technical holes, which is the biggest security risk. This is why people are gradually turning their attention to 3D live fingerprint recognition technology.
The so-called 3D living fingerprint recognition technology uses the capacitive sensing theory to let the electronic signal directly capture the dermal fingerprint. Since the fingerprint dermis (live) information is collected, the verification is not affected by the wet and dry fingerprints and the like. Secondly, it does not recognize the silicone fingerprint sleeve without the dermis layer. In this way, the 3D living fingerprint access control completely compensates for the defects of the traditional optical fingerprint access control, while retaining the advantages of simple and practical fingerprint recognition technology.
Compared with the traditional optical fingerprint access control system, 3D live fingerprint recognition technology can prevent artificial fingerprints through biological living body sensing. With the increasing demand for safety, the 3D live fingerprint access control system with obvious advantages such as high performance and high security has been widely used and applied because it meets the needs of families and enterprises with increasing safety requirements. .
In terms of safety and security, in order to keep the family and the safety of their own lives, it is no exaggeration to keep more vigilance. The most fundamental thing about 3D live fingerprint recognition technology is that it uses new technology to make up for the shortcomings of traditional technology and meet people's needs.
