As we all know, Samsung has become the world's leading storage, panel, image, processor R & D manufacturing industry chain, with advanced and unique hardware innovation to become the absolute overlord in the field of consumer electronics, hard power leading the wave of technology. Samsung Notes 7, which has been hailed as the flagship machine of the year, is the most exciting among the many hardware technologies that are equipped with iris recognition. Advanced technology brings excellent user experience comparable to fingerprint recognition.
Because fingerprint recognition is still an extension of touch sensing technology, iris recognition is a re-extension of image sensing technology. The latter obviously has more technical reserved space in human-computer interaction. This may be Samsung's choice of iris recognition. Technical reasons.
Samsung uses the flagship Note 7 of the year to promote iris recognition and create differentiated hardware application functions. It is clear that the technology is full of confidence. Samsung's consistent model is to apply advanced and mature technology to its flagship mobile phone promotion. Under the premise of ensuring profit, the company will develop capacity supply to other manufacturers, and then build an industrial chain in the world, using the first-mover and scale advantages to occupy the top of the pyramid. interest.
Compared with the current popular fingerprint recognition and face recognition, iris recognition has an absolute advantage in comprehensive safety performance such as accuracy, stability, reproducibility and living body detection. Iris recognition is the most accurate identity authentication technology among all biometric technologies currently known, because only the iris of the eye is the biological sign that has remained unchanged since birth and is a living biological sign. It is reported that there are already 1 billion orders of iris libraries in India, and there is great potential for mainstream identification technology in the future.
Iris recognition is widely regarded as the most promising biometric authentication technology in the 21st century, and Samsung has been cultivating the mobile payment market for many years. The known information is that Samsung has started commercial application for iris recognition technology and patent protection many years ago. .
With the continuous development of intelligent terminals, the diversity and changes of application scenarios, especially in mobile payment and virtual finance, fingerprint recognition technology can not meet the higher level of security protection and identity ID requirements, and the new technology of iris recognition card position Come, this is the market reason for Samsung to choose iris recognition.
The biometrics market is growing rapidly and the growth rate of iris recognition is outstanding. Iris recognition has been widely used in the fields of finance, medical care, security, security, etc., providing an ecological basis for the popularization of consumer electronics. The interaction and blending of different application scenarios will effectively improve the penetration acceleration of iris recognition and the enrichment of ecosystems. According to a report published by the US think tank AcuityMarkeTIntelligence, the global biometrics market is expected to reach US$21.87 billion by 2020, of which the market share of iris recognition technology will increase from 7% in 2015 to 16% in 2020, and the total output value in 2020. It will reach 3.5 billion US dollars, corresponding to a compound annual growth rate of 36.6%.
Protecting information security and personal identity unique ID is the biggest application advantage of iris recognition. With huge market demand, competitors are not strong, and the timing of technological breakthroughs is coming. Does Samsung bet on iris recognition to drive the development of the industrial chain? What is the main part of the iris recognition industry chain? Will iris recognition be the next vent? What is the latest development of domestic iris recognition?
Decoding Samsung Note 7 iris recognition technology
The method of iris recognition was first proposed by American ophthalmologists Leonard Flom and Arin Safir in 1987. The algorithm for iris recognition was developed by Dr. John Dargman of the University of Cambridge. He proposed a mathematical algorithm for encoding and comparing irises. Because of the complexity of the equipment, the scanning distance is short (generally required to be within 7 inches), and the user's psychological health concerns, but not used in the civilian market.
The process of iris recognition technology is generally divided into four steps: iris image acquisition, image preprocessing, feature extraction and feature matching. A few years ago, Samsung worked with Yonsei University's Biometrics R&D Center to create an iris recognition system (iris recongniTIon technologis). Samsung Electronics has been confirmed to apply for an iris recognition technology patent in May 2012. In the recent exposure of the iris patent, Samsung's technology accumulation in iris recognition is very mature.
Samsung has applied for a new patent from the US Patent and Trademark Office. The data shows that Samsung is considering using three cameras to provide iris recognition.
According to Samsung's introduction, the iris recognition system can capture images of the user's face and eyes and then generate image signals. The iris recognition system captures image signals with three lenses. Based on the generated images and other information, the system can check the user's iris. When the iris recognition system operates in the iris recognition mode, the application processor can control the system output data, which is consistent with the visible light image and the infrared light image.
Under the control of the application processor, the illumination device "LighTIng Device" emits infrared light to the user's eyes. The application processor can also control the iris recognition system to operate in two modes: front camera mode and iris recognition mode.
