During the Spring Festival this year, Xi'an North Railway Station passengers through the face recognition system with the help of staff ticket check. Focus on biometrics: From the lab to the public Vendor demonstrates smartphone with iris recognition. Image from the web How old is his or her phone? There was a small game based on face characteristics to test age brush burst friends circle. The reason why this game application can accurately predict age, gender and other information lies in the embedded face recognition technology, and the function of the technology much more than this. Face recognition technology belongs to the biometrics (hereinafter referred to as biometrics) technology. In recent years, biometrics, typified by face recognition and iris recognition, have moved from the laboratory to the public and upgrading people's "passwords" will make our lives more convenient and safer. What is biometrics? Everyone has a unique iris texture and stays the same for life Biometrics, in simple terms, is a way to use personal physiology (fingerprints, face etc.) or behavioral characteristics (sounds, gait, etc.) for personal identification. In general, human biometrics have the advantages of being portable and difficult to counterfeit, and have the advantage of being confidential and convenient to identify. Common biometric identification is fingerprint identification, but fingerprints easily leave traces of others copied, but also the finger cleanliness, dryness requirements are higher. With the advent of the Internet of Everything, data security and privacy are becoming more important, and people need safer and more effective "passwords." Face recognition is the more mature biometrics. Because of each person's facial features, facial features are different, which makes use of these features to identify individuals as possible. National Information Technology Standardization Committee of Biometrics Subcommittee experts, Beijing Science and Technology Co., Ltd. Kuangsheng Zhang Xin, director of marketing, said the physical characteristics of the face can be transformed into computer data identified by the information. Face recognition technology, the first face or face detected in the image or video, and then target the key features of facial features to locate, extract features and structured processing. With these data, the computer can analyze the face attributes, read face. Face recognition technology to benefit from the application and development of artificial intelligence related theories.At present, the mainstream face recognition technology mainly combines depth learning algorithm, the more the machine to see the face, the more training data, the deeper the understanding, it The more accurate the human face, the more rapid. "Zhang Xin said. Iris recognition is another biometric technology favored by the industry. The iris is an annular area located between the black pupil and the white sclera on the human eye surface and contains many interlaced spots, filaments, crowns, crypts and other details. Institute of Automation, Chinese Academy of Sciences researcher Sun Zhendan said iris recognition technology by comparing the similarities between the iris image features to confirm the identity of the person, the core step is to use pattern recognition, image processing and other methods to describe the human iris feature data values ​​?? at the same time , The obtained iris data and the stored iris information are matched and classified to achieve the purpose of confirming the identity of the personnel. He Zhaofeng, a member of the International Biometrics Technical Standards Committee and deputy general manager of Zhongke Hongba, said iris has many advantages as an identifier. First, iris recognition is safe. Everyone has a unique iris texture, even with the same person's left and right eyes or identical twins, the iris texture is also significantly different. Second, the iris texture is formed during the third to the eighth months of embryonic development and remains unchanged for long periods with good stability. In addition, iris image acquisition without contact, easy to use. As with face recognition, Iris recognition breakthrough also benefits from the development of artificial intelligence. Sun Zhenan said that in recent years, the outbreak of biometrics is not only driven by the recognition technology itself. It is the inevitable result of the development of social informatization to a certain extent. For example, the development of intelligent terminals makes iris data collection more convenient, and big data analysis methods improve the accuracy of data alignment, interconnection of all things and the ensuing higher requirements for security, allowing biometric identification Useless. Lei Zhen, associate professor of automation at the Chinese Academy of Sciences, said in recent years, including face recognition, including recognition technology to enhance, first, thanks to new chips and new algorithms to bring the computing power to upgrade; second mobile phones and other intelligent terminal equipment The popularity of large-scale low-cost data collection possible. What can biometric do? Shopping malls, banks to withdraw money ... These daily business "brush face" "brush eye" can be completed At present, face recognition technology has entered the public field of vision. Rushed to the office early in the morning, holding hot coffee, whether you will not be able to make a permit to dig documents and credit card to worry; work overtime at night back home, dig pocket, because you forget the key to the room and depressed. With the face recognition system, all this worry does not exist, you only need to "brush face", access can be automatically unlocked, and even according to your mood to send the appropriate greeting. Smart Security is an important application area of ​​biometrics. Due to the different biological characteristics, life-long features, so that it can show its mettle in the security monitoring. For example, the use of face recognition technology, through dynamic monitoring, to map search, portrait comparison and other means, not only to understand who entered your community, but also to help public security organs and improve the security system. Zhang Xin said that a large number of fugitives have already "bleached" themselves by posing as other people. Face recognition can "see" the true identity of such people, thus exuding cocoon from the massive population and accurately identifying and alarming. In the field of smart business, the application of biometrics is gradually expanding. "To the bank account must take an ID card to verify identity, not only the delay time, but also to bring some inconvenience to those who have trouble.With the face recognition system, online verification will be able to complete the real name." Zhang Xin said. In the future, real-name validation becomes even more important when traditional industries such as finance, telecommunications, government services, and education move online. In these fields, there is a lot of room for imagination in future biometrics applications. Zhangjiagang Liyuan Conveyor Machinery Co.,Ltd , https://www.zjglyssjx.com
