Nowadays, the various unlocking methods of smart locks are dazzling, and the most interesting one is face recognition and fingerprint unlocking, which has also triggered a discussion among consumers about which of the two unlocking methods is more secure, so which one is more secure? The editor of Romance has sorted out some data for you to help you distinguish.

Face recognition intelligent lock is based on face recognition technology. It can recognize and process the input face image or video stream by collecting the features of human face. The recognition process is to determine whether there is a face. After recognizing the face, scan the position and size of the face and the position information of each main facial organ. Then, based on these information, further extract the identity features contained in each face, and compare them with known human faces, so as 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. But its disadvantages are also obvious at present, mainly in the following two aspects:

First of all, the face state is unstable and vulnerable to external factors. The main body of face recognition is human face, and unlike fingerprints, human face is unchangeable. Eyelashes, glasses, masks, hairstyle and external light can easily affect human face features, thus affecting human face recognition.

For example, when you come back home from work, you have to take off your mask, scarf, hat, glasses and then take care of your hairstyle to get in. After the face recognition is OK, you may have wet your pants. Do you think the convenience of the face recognition smart lock is funny at this time. The smart lock of my building door supports both face recognition and fingerprint recognition, and face recognition can only be unlocked in about 10 seconds each time, so I always brush my fingerprint directly for the sake of speed, and have no time to pose to brush my face.

Secondly, the power consumption of face recognition lock is relatively large. The ordinary fingerprint lock is equipped with 4 dry batteries, and the power consumption is basically only used for fingerprint identification. Generally, it can be used for about one year after replacement; The energy consumption of face recognition in acquiring face is far greater than that of fingerprint lock in acquiring fingerprint. At the same time, it is also necessary to enable light supplement in dark situations, or to change the battery or charge it frequently.
