Face recognition is a biometric identification technology based on a person's facial features and information for authentication. The most important feature of the technology is that it avoids the leakage of personal information and uses a non-contact method of identification.
Face recognition and fingerprint recognition, palm print recognition, retinal recognition, bone recognition, heartbeat recognition, etc. belong to the human biometric identification technology, are with the rapid development of photoelectricity technology, microcomputer technology, image processing technology and pattern recognition and other technologies should come into being. It is fast, accurate and hygienic for identification; it is non-replicable, and even after cosmetic surgery, the technology can identify the "original you" from hundreds of facial features.
Face recognition systems have been widely used around the world. In China, it has been widely used in public security, security, customs, finance, military, airports, border control, security and other important industries and fields, as well as intelligent access control, door locks, time and attendance, cell phones, digital cameras, smart toys and other civilian markets.
Under the global environment of advocating digital life, people's demand and enthusiasm for "face swiping" is almost increasing day by day. China is a large country with the world's largest population base. The development potential of face recognition application is particularly important in China at this stage. With a huge population base and more and more frequent mobility, how to make full use of high technology to accurately identify the 1.4 billion people, and then widely used in various industries, is a big topic related to the management of the whole country. If the face recognition system is used in the ATM machine, it will bring a lot of convenience and safety to people's life.
In May 2017, Beijing Normal University piloted the "brush face". Doorway "face" access control machine a **** two, dormitory door inside and outside each one, in and out of the door need to "brush face". "Brush face" access control is about 1.7 meters high, the top of the machine has a face recognition screen, a camera on the screen below each, can identify students of different heights. Below the screen there is also a numeric keypad and swipe area. Enter a string of numbers on the numeric keypad, then look directly at the machine screen, face recognition is successful, the machine issued a "welcome home" sound. After successful facial recognition, if not immediately open the door, about three or four seconds, the dormitory door will be re-locked.
