After years of development, face recognition technology has made great progress. At present, face recognition has been used in various fields of people's clothing, food, housing, and transportation, ushering in the "blowout period" of use. Experts believe that face recognition technology will continue to make breakthroughs in the future, and its application areas will continue to expand.
Entering passwords, fingerprint recognition, voiceprint authentication, face recognition... Human society has undergone several changes in security protection in the history of human society. Each change is accompanied by the continuous development of technology and the public's recognition and acceptance of technology.
Due to the natural attributes of smart devices, it is more common to carry facial recognition functions on mobile phones. Face payment, face unlocking and other functions abound in new products. Apple, Xiaomi, VIVO, etc. have all launched facial recognition. Functional products. Some smart TVs are also equipped with face recognition functions, such as child locks. Face recognition also has unlimited potential in the fields of public security criminal investigation, identity management, station security, unmanned retail, banking and finance, and image management. .
In 2016 and 2017, the state successively issued the "Internet + Artificial Intelligence Three-Year Implementation Action Plan" and the "New Generation Artificial Intelligence Development Plan", which raised artificial intelligence to the national strategic level, and at the same time, accelerated the growth of artificial intelligence in education and medical care. , Smart city, smart home and many other applications, face recognition has also become one of the application directions and has become a key research and development project in the field of artificial intelligence.
Face recognition technology began in the 1960s, and it has been half a century since it has been based on human facial feature information. It is another kind of biometric technology. In terms of scope, it includes face image acquisition, face positioning, face recognition preprocessing, identity confirmation, and identity search; from the field of integration, face recognition technology combines biology, psychology, cognition, and pattern Recognition, image processing, computer vision and other multi-dimensional fields; in terms of accuracy, face recognition technology has achieved a major breakthrough. At present, the highest accuracy rate of the face recognition system can reach 99.5%, which is higher than the 97.52% of human eye recognition. Accuracy.
At present, my country's face recognition level is among the top in the world. As we all know, one of the foundations of artificial intelligence is big data. China has a large population and complex environment, which has laid a data foundation for face recognition. Compared with other biometrics such as fingerprint recognition and iris recognition, face recognition has weaker privacy, has the advantages of intuitive, concise, and fast, so it is more likely to be favored in business.
However, because human faces are often dynamic, there are inevitable disadvantages in terms of technology, such as the position of the recognized person, the light, the angle of the face, movement, occlusion, repair/disfiguration, makeup, age and even expression, twins, etc. Will have a certain impact on the accuracy. In order to make up for this shortcoming, in the current stage, either static face recognition is used, or dual guarantees of machine recognition and manual verification are used.
Specific to the application field, the areas most exposed to the public should be bank verification, airport/station/security inspection/customs clearance/hotel verification, and new retail.
Many banks will use digital password + face verification in large-value transfers, identity verification and other steps to protect the user’s property security, such as China Merchants Bank; some banks have also introduced the "face-based withdrawal" function, such as Agricultural Bank of China and China Merchants Bank, of course, will assist mobile phone number verification and password verification in order to prevent the error rate of one in ten thousand.
Airports, stations and other security checks and customs clearance entrances will also be equipped with certain face verification methods. As of July this year, many airports have adopted face recognition technology to enable passengers to assist or self-check customs, such as Shenzhen Baoan Airport and Shanghai Pudong Airport and Shenyang Xiantao Airport have greatly liberated manpower and improved the efficiency of security inspection and customs clearance.
The new retail area is also another area where face recognition can show its talents. Through face recognition, customers can enter unmanned retail stores to complete a series of operations such as shopping and payment for goods. It can also play a certain security role, and at the same time Data collection and optimizing operations of retail stores also play a significant role.
From being suspicious to being convinced, from being perplexed to being suddenly enlightened, like other authentication methods, face recognition has gone through multiple stages of development from technology, society, and economy. The birth of new things is always accompanied by doubts and constraints, but space and development are the broad prospects of new technologies. It is believed that in the near future, face recognition technology can be more widely used in all corners of life, bringing smarter and more convenient social life to the public.
