Nowadays, there are a lot of intelligent lock unlock technologies. In addition to conventional password unlock, there are also "black technologies" such as fingerprint unlock, APP remote unlock, face unlock and finger vein unlock. Which technologies are more mature and reliable?Fingerprint lock is often seen in the market. Is it a smart lock worth choosing?Next, small make up take everybody understand together!
It is understood that bluetooth, keys and passwords are the basic ways to unlock smart locks, not as the technical division of smart locks.APP can only be used when intelligent lock supports online mode. It is not a necessary function of every intelligent lock, nor is it a judgment condition for intelligent lock type.Therefore, the intelligent lock is mainly distinguished according to the biometrics.
The technology of biological identification mainly refers to the technology of identity authentication through human biological characteristics. The biological characteristics of human beings are usually unique, measurable or automatic identification, hereditary or permanent. Therefore, the technology of biological identification authentication has great technical advantages.
Fingerprint identification is the most mature and widely used biometric identification technology in intelligent lock, which can be divided into optical fingerprint lock, semiconductor fingerprint lock (capacitor type, inductance type), radio frequency fingerprint lock, etc.Among them, optical fingerprint recognition technology has low security and is generally used only in low - and medium-end products.Radio frequency fingerprint (also known as 3D fingerprint identification technology) locks are expensive and have few applications.-js53660金沙官网登入On the market, most high end fingerprint locks are made of semiconductor fingerprint identification technology.
Finger vein recognition technology, that is, through the collection of finger vein characteristics to identify verification, is a relatively safe biometrics technology.However, the core technology is in the hands of foreign enterprises. There are not many domestic enterprises that can develop the digital vein identification module.-www.js848.cc
Face recognition technology, that is, through the acquisition of face 2000 or even thousands of feature points to identify authentication.At present, the face recognition technology in smart locks is almost all 3D modeling with dual cameras, and the help of infrared detection of features inside the face, claimed to have the ability to identify twins.-9159金沙游艺场However, from the advanced 3D face recognition technology, the security needs to be verified.
Iris recognition technology is to capture the iris data image to identify verification.Iris recognition may be a promising biometrics technology, but the equipment is too expensive to be widely popularized, and the lens may produce image distortion, reduce reliability, and it is difficult to be widely popularized in a short time.
In conclusion, fingerprint identification is the most mainstream and mature identification method in the intelligent lock industry.Fingerprints are a unique characteristic of everyone and are highly secure.When reading a fingerprint, the finger and the fingerprint sensor touch each other and scan the fingerprint quickly, which is very convenient to use.The technology is mature and it is difficult to break into forged fingerprint, which is the main reason why fingerprint lock can occupy most of the market of smart lock.More and more smart fingerprint locks will be introduced into tens of millions of families in China, making people's lives safer and more convenient.-金沙9159游艺场官网
