'By foil means, we can achieve a fingerprint cracked smart phones.' Mindray Microelectronics Co., Ltd. Suzhou, chairman and chief technology officer Li Yang Yuan said recently that the fingerprint chip industry led by the FBI in the early design fingerprint chip technology route of the algorithm , The first consideration is to avoid security risks.At present, the market has mass production of fingerprint recognition chip can be cracked under certain conditions.Any commercial software (including ios, windows, android), may be in the user process Found problems, usually by pushing the user to solve the patch.
Safety value is higher than safety cost
Then face the fingerprint identification industry has existed problems, but also how to deal with? LiYangYuan in the 'security fingerprint article life --Merui micro security fingerprint technology conference' on the one hand, before malicious attackers found the problem, on the other hand But also to urge the industry to correct the problem and avoid further proliferation of the problem.This is also the value of corporate research and safety, not the cost of safety, but to study the cost of breaking the security industry.

Li Yangyuan further said that Mindray Micro is currently optimizing the level of exclusive algorithms to avoid such problems. 'Fingerprinting has two key elements: one is safety and the other is quality.' At the event venue, Mindray Micro released three An embedded fingerprint module product line, namely Microarray ECS 120, ECS 160 and Microarray ECS 256. The Microarray ECS256 size of 256 × 360, for the security industry, in line with ID card specifications; and for intelligent security applications such as door locks IoT The Microarray ECS120 and ECS160 series realize the compatibility of various system configurations and better achieve the structural design integration under the Internet of Things era.
The technical advantages of this embedded fingerprint module with ring-free anti-static, ceramic anti-knife, anti-attack algorithm, the state secrecy level security processor, Bluetooth low energy, the smallest size (PCBA 18mm x 18mm), built-in ID2 Li Zhiyuan Li Yang Yuan said that from the basic configuration, security configuration to the wireless configuration, the new product has the structural backward compatibility, high reliability, high security performance advantages, will help terminal manufacturers continue to upgrade products.
Visible in the smart phone market, Mindray Micro is also developing the IoT market, Li Yangyuan called the 'two legs to walk.' Li Yang Yuan said in the field of IoT, Mindray Micro has two roles, the first one we as a sensor IC's role , Is the sensor standard and fingerprint recognition algorithm to provide the appropriate advice.Second, we are also a fingerprint module manufacturers a role.Merie micro fingerprint module to do different levels to enhance, to solve the problem of information security, and the lock factory to continue Solve the physical needs of traditional strong, that is, the issue of physical 3C, this is a more in line with the technical strengths of all parties. Li Yang Yuan stressed that the security of fingerprint chip industry and many industries are not the same, it is a lot of industries to the next level Layers of each level can be set standards, and security is buckled up each link, a rigorous deduction into a chain.This chain of work to be done by the terminal manufacturers is unrealistic, there should be a group of companies in the background all the things Solve, give the terminal manufacturer a simple installation standard, this is the best industry solution.
Under the screen fingerprint recognition optical fingerprint program
Mindray Micro that is making progress along both sides is obviously still dominated by the mobile phone market. In the application of mobile phone fingerprint recognition technology, Mindray Micro is also cutting into the fingerprint identification technology of the next generation screen.
'Mindray Micro's under-screen fingerprint ultrasound and optical solutions are in the normal course of progress, and the optical solutions are based on my estimation of these actual progress in the industry unless someone wants to impress with infrared. "Li Yangyuan said that infrared acquisition Fingerprint has an inherent defect, that is, we use infrared reflection of visible light through the ink to draw a pattern, plus we now have seen many of the algorithms have such defects, draw a pattern to put it cracked, engage in poor will Let screen fingerprints are easily cracked.
Of course, if it is done with visible light, this is indeed very difficult, which is related to the structure of the OLED.One of the manufacturers open the OLED, resulting in reduced resolution, perhaps in order to install the fingerprints may not expensive, the cost value of the OLED can be relatively more expensive .
LiYangYuan revealed that the difficulty of optics OLED remain fixed, and the cost of ultrasound is the material, Qualcomm ultrasound program is also stuck in the material above. There are two kinds of ultrasonic materials, one is high temperature a low temperature, low temperature is too low temperature , Probably more than a hundred can still live, so consumer electronics okay, industry can not; and high temperature materials than other high temperature, so the normal design of ultrasound in fact to explore.
However, at present, judging from the progress of application in the market, the fingerprint technology under the screen will introduce the mass production of the mobile terminal into the mass production in 2018, realizing commercialization. However, whether the optical fingerprint technology or the ultrasonic solution wins the game depends on the feedback of market products User's voice.
