China’s biometric market has maintained rapid growth. In recent years, China will promote biometric standardization in the fields of information technology, information security, financial transactions, social security and so on, with great industrial potential. Physiological features are innate to human beings, mainly including hand shape, fingerprint, face shape, iris, retina, pulse, auricle, etc. based on these features, people have developed a variety of biometric technologies. At present, the more mainstream recognition technologies include face recognition, fingerprint recognition, rainbow recognition, vein recognition, speech recognition and so on.
In recent years, the identity recognition technology is becoming more and more mature, and the application scenarios are expanding. It has achieved good performance in various fields of application, and has remarkable performance in solving security problems and improving work efficiency. From the perspective of global market, the global market scale of identification technology reached more than 10 billion US dollars in 2016. With the integration and diversified application of multiple identification technologies, emerging industries across biotechnology, security, it and other fields have been formed, which is expected to reach more than $20 billion in 2021.
The Research Report on the market analysis and development prospect of China’s fingerprint identification system from 2017 to 2021 released by xinsijie industrial research center points out that: from the perspective of market segmentation, fingerprint identification currently occupies a dominant position. By 2021, fingerprint identification will still occupy the global mainstream, accounting for more than half; Speech recognition and face recognition followed; The proportion of iris recognition will be greatly increased, and new identity technologies will also be applied. From the domestic situation, although China’s research in the field of biometric technology has reached the world’s advanced level, the current application scale and penetration rate are still very different from those in the European and American markets. In addition, the current industry growth rate is stable, and it is estimated that there will be great development space in China in the future.
From the development status of major biometric applications, fingerprint identification technology is mature and low-cost; Face recognition is easy to use and suitable for public safety and other fields with many groups; Iris recognition has high security, but the cost is too high, and it will take time for it to be popularized. From the application of various biometric technologies, fingerprint recognition accounts for a high proportion, and face, iris and other recognition technologies are growing rapidly.
New thinking industry researchers believe that compared with other biometric recognition methods, face recognition has the advantages of naturalness, imperceptibility and so on. Naturalness means that the recognition method is the same as the biometrics used by human for individual recognition. Fingerprint recognition and iris recognition are not natural. The imperceptible characteristics make this recognition method difficult to conflict with. Fingerprint recognition or iris recognition requires the use of electronic pressure sensors or infrared to collect fingerprint and iris images, which has a poor sense of experience in the acquisition process. At present, the problem to be solved in face recognition is how to ensure the recognition rate in different scenes, face occlusion and other applications. In addition, privacy and security are also worth considering.
