Screen fingerprints quickly on | safety is still a consideration

Fingerprint recognition module thickness, power consumption continues to decrease Security is still an important consideration

One of the challenges of using under-screen fingerprint recognition in a full-screen mobile phone is the module's thickness and power consumption. Godfrey Cheng, vice president of marketing at Synaptics, said: 'The Clear ID consumes low power and is suitable for Android low-power mode. The first generation of modules The vertical height is only 0.69mm. For today's smart phones, there is no problem with the use. Looking into the future, we will continue to reduce the power requirements of the module and reduce its physical size.

According to Lin Ruijian, general manager of Duntai Electronics Group and Dentex Optoelectronics, 'aTOM onFlux ID solution does not follow the traditional penetration technology's comfortable R&D direction, but uses patented nano-micro-opto-electromechanical fingerprint sensing technology to try to avoid a full screen mobile phone. The more sensitive space locations, such as the space below the AA display area, are all given to the battery, and are captured in a destructive innovative optical waveguide method, resulting in low power consumption. The small module area does not occupy the battery position, and there is no distortion and no Due to the influence of strong light, the reaction speed is fast, the cost structure is reasonable, there is no need to change the panel design, and it does not affect the obvious advantages of the panel process. Of course, any destructive innovation must have the full range of technical breadth and depth of technology. MEMS design and SiP system-level packaging technology is one of the key technologies that Dunjie will have to master 100% of its fingerprints under ultra-thin and low-power aTOM onFlux ID screens in 2018.

Therefore, under the joint efforts of the whole industry chain, under-the-screen optical fingerprint products that meet the requirements of full-screen mobile phone size, power consumption, and functional requirements are gradually introduced to the market. However, fingerprint recognition is inevitably used as a biometric method in mobile phones. Unlock and pay for the scene, so security can not be ignored. Lin Ruijian said that due to mobile phone security verification and payment verification in different application levels of different requirements, so aTOM OnFlux ID in the security verification stability and user experience beyond comfort Depending on the application, biosafety verification can be enhanced with higher security; for example, adding biomedical information (heart rate, etc.) during biometric verification, biometric biometric identification to enhance safety, and real-time artificial intelligence pseudo fingerprints for power-on safety verification. Identification technology to increase customer experience comfort.

Godfrey Cheng introduced: 'Synaptics is a founding member of the FIDO Alliance. The Synaptics SentryPoint Security Suite includes SecureLink technology that also supports TLS protocol, ECC authentication and AES encryption. This highly secure transmission is protected against the latest industry standards and can be protected. End-to-end transmission of data from the fingerprint sensor to the host. The Synaptics Quantum Matcher technology is used for fingerprint template matching and authentication.

Fingerprints on the screen will speed up the future Fusion with 3D face recognition enhances security

It can be seen that different manufacturers of fingerprint identification chips have their own solutions for solving problems such as screen penetration, identification capability, size, power consumption, security, etc. The mass production progress is not the same. Vivo with Synaptics Clear ID X20 Plus UD has been fully put into production, this production model can also achieve fingerprint recognition in a specific area of ​​the screen. Lin Ruijian optimistically speculated that onFlux program will quickly increase in one year, and have the best chance to become the most widely mobile phone industry in the future The use of fingerprint security and payment verification program under the screen, in particular LCD mobile phone screen fingerprint program.

Huidi Technology, a domestic manufacturer of fingerprint identification chips, is also actively researching under-the-screen fingerprinting technologies. At the Computex 2017 Taipei Computer Show, the Samsung Galaxy S7 edge was used to display the progress of its fingerprints on the screen. However, it can only be used on AMOLED screens, and the unlocking speed is also high. It has not yet reached the level of traditional touch fingerprinting. On MWC 2018, Huiding Technology released its second-generation optical fingerprint technology under the screen, which is characterized by better performance and better user experience. It is expected to achieve mass production in 2018.

In addition to the rapid advancement of fingerprint manufacturers under the optical screen, Sweden FPC also announced in November 2017 a solution that can capture and identify user fingerprints anywhere on the mobile phone display panel. It is reported that the in-display technology is based on ultrasonic sensor technology and can be worn. The 2cm-thick glass acquires fingerprint information and supports OLED and LCD display. However, the mobile phone equipped with this solution has not yet been released.

Obviously, with the increase of the overall screen penetration rate and the mass production of the fingerprint identification programs of major fingerprint identification chip manufacturers, we will see that the Android camp has become the mainstream with full screen and fingerprint under 2018, but the initial cost of mass production is difficult to solve. Avoiding, still needs time on a large-scale application on mobile phones.

Finally, for the issue of under-screen fingerprinting and 3D face recognition who will become the mainstream of mobile biometric recognition, the two interviewed experts stated that the future is an era of multiple biometrics recognition. Lin Ruijian stated: 'In order to increase the stability of funding security and payment verification Sexuality and safety, but also in order to increase the biometric security while taking into account user experience comfort, the future will be the era of multi-mode biometrics. With our understanding of the competitiveness and maturity of aTOM onFlux ID, the future will be iPhone New models or high-end models in the Android camp may push forward the direction of dual-mode biometric recognition for fingerprint recognition under the screen and 3D face recognition. From the perspective of the experience and habits of human-computer interaction user experience, the fingerprint recognition application under the screen is comprehensive. Screen phones will play a more critical role than 3D face recognition. 'Godfrey Cheng also stated that Clear ID is easy to use, has excellent security, and unlocks more than twice the speed of 3D face unlocking. Future, multiple biometrics fusion The engine will further improve security.
