微众银行联合腾讯优图推出光线活体技术,看看背后的技术原理

Recently, the computer vision technology companies such as open, according to science and technology to get a series of hundreds of millions of financing news full of eye-catching, according to Lei Feng network understanding, investment institutions are behind the traditional financial institutions. In face recognition in the financial industry has been more and more widely used at the same time, Lei Feng noted that in addition to science and technology company also, there are some new financial institutions involved in this area of.11 8

According to reports, the micro public banks, Tencent and Tencent and so on an all day long Royal excellent map based on the practice experience, to create a face recognition based on KYC (Know Your Customer), also known as the financial level of multi factor authentication service in face recognition as the core. Multi factor includes ID card OCR and verification, bank card OCR and three or four elements verification. Support SDK, WeChat public number, small program and other channels access.

In face verification, in vivo detection techniques include live motion, digital living, light living and so on. Among them, the light is in vivo biological recognition microchinese upcoming feature technology, its principle is reflected by the screen form random color changing light on the face after the portrait of 3D, in combination with other anti attack model microchinese background, to complete in vivo detection by the principle of physics, can resist the video, HD 4K screen model, attack. The main advantage is that:

  • In the user experience, this technology does not require any action interaction, just a short gesture to maintain, you can instantly brush face verification;

  • There is no need for custom hardware in the platform and model universality, and the use of all mobile devices and brush machines is supported;

  • In the safety performance, different color and intensity of light emission through the screen, projected onto the face and received by the camera, and then a series of algorithm processing and convolution neural network, including the changes of light signals from the video analysis, and 3D face and texture information is required in vivo judgment, at the same time, the method based on the solid foundation of cryptography, is one of the highest level of security currently known technology.

According to the introduction, light living technology compared with Apple's latest facial unlock, the hardware requirements are lower. The principle of iPhoneX facial unlock function is that the infrared camera at the top of the phone screen captures nearly 10000 feature points of the face, 3D imaging. Through imaging and then the background detection and comparison, mainly rely on hardware to complete. The principle of structure light principle, but not all mobile phone users have infrared camera configuration, the use of mobile phone consumers mostly in the low-end mobile phone.

In addition, the KYC service and integrated with the cloud security day Royal products, to provide anti fraud cloud security solutions for various industries, such as consumer credit / cash installment, live, love and marriage platform, including cash / consumer loan is particularly prominent. As well as, insurance, securities, direct bank, government business, telecom online business the needs of all nuclear body service. Microchinese said, the cumulative technology provides services face nuclear body 20 million times, and that the future KYC services will become a basic service, has great potential.

It is worth noting that earlier this month, the ant payment service's global trusted identity platform ZOLOZ (Zorro) announced the successful development of the first global eye recognition technology, and has realized the eye pattern recognition by ordinary mobile phone, in the laboratory scene has been able to identify extreme looks identical twins are similar. Both emphasize safety for hardware requirements is not high and higher, but a new information and feature library, or a person's facial features information based on the identification, because of two kinds of technology are put into practical use, the application effect of the future that how Lei Feng network will continue to follow-up reports.
