Comparison between face recognition lock and fingerprint lock which smart lock is more practical

There are endless smart lock products. There were password locks, fingerprint locks, and so on. Now they have more face recognition locks. So what kind of practicality is the face recognition smart lock compared with our commonly used fingerprint lock? Here we compare the technical and security aspects.

Face recognition technology is based on human facial features and performs recognition processing on the input human face image or video stream. The recognition process firstly determines whether or not there is a human face. After the human face is recognized, the location, size, and position information of each major facial organ are scanned, and then the identity features contained in each human face are further extracted based on the information. , and compare it with a known face to identify the identity of each face. Compared with fingerprint recognition, its main advantage is that the face recognition lock can actively obtain user information without user contact.

Although face recognition technology has been applied in many fields such as security, but most of the ordinary consumers still remain in the movie screen. Fingerprint recognition technology has been developed for more than 20 years. People have already trusted and recognized fingerprint identification technology. With the use of fingerprint unlocking in mobile phones, people are even more interested in fingerprint identification technology products. For strange face recognition technology, people only have their watches, this technology has not shown more charisma to the public, so people's attitude towards face recognition locks is more curious, questioning and wait-and-see. In fact, there are many hidden dangers in face recognition.

From the technical point of view, the face state is unstable and there are many factors that are easily influenced by the outside world. The subject of face recognition is the face, and the face is not as stable as the fingerprint. Eyelashes, glasses, masks, hairstyles, and external light can easily affect the features of the face, thus affecting the recognition of the face. In the process of using face recognition locks, people need to take off masks, collars, hats, glasses and then take care of hairstyles when they enter the door. The convenience of smart locks seems to be funny.

The power consumption of the face recognition lock should be one of the concerns of the consumers. The ordinary fingerprint lock comes with four dry batteries, and the power consumption is basically used only for fingerprint recognition. Therefore, it is normal to replace the battery for one year or so. Face recognition locks consume more energy when acquiring faces than fingerprint locks, and also need to enable light fill in dark places, or need to constantly change batteries and charge. Inadvertent power shortage may cause door opening. life.

Overall, the face recognition method allows people to feel a new wave for the time being, but its practicality, convenience, stability, and security are still slightly inferior to fingerprint locks. Therefore, Xiao Bian suggests that you choose the smart lock that suits you, and don't blindly follow the trend.
