Iris recognition enters the smart door lock providing exclusive security barrier

with the popularization of fingerprint recognition and face recognition, the evolution of biometric technology is still in progress. Iris recognition, as a more secure biometric technology, is regarded as an important technology reserve by major technology companies to plan how to seize the commanding point and initiative before the outbreak of the market.



However, when fingerprint recognition and face recognition have basically met the daily needs, iris products have a very low sense of existence in the consumer market. The application is relatively simple, the price is generally high, and the ecology is not perfect. All kinds of signs seem to confirm the same argument: "iris recognition is an unnecessary function" To this end, analysts of international e-commerce visited the iris recognition industry in China and discussed with experts how to promote the public into the "eye brushing" era.

The development history of twists and turns

the eye is the window of the mind and the symbol of identity. The human eyeball includes the eyeball wall and its contents. The iris is located in the circular part between the cornea and the lens, There are many texture features of iris, which are similar to the shape of spots, filaments, crowns, stripes, wrinkles, dimples and so on. They all have the characteristics of individual uniqueness, life-long stability, live anti-counterfeiting and so on. They are the only biometrics that can accurately identify the identity at present. According to data from the Chinese Academy of engineering, compared with fingerprint recognition of 0.8% and face recognition of about 2%, the recognition error rate of iris recognition can be as low as one in a million.



Therefore, iris recognition has great market potential. It does notOnly in line with high security requirements and high-precision national identity authentication scenarios, it can also be widely used in finance, medical treatment, security, security, attendance and access control of special industries, industrial control and other fields. In fact, the two most widely used areas of iris recognition in the world are the public security department and national security, with no exception at home and abroad. For example, the U.S. Department of defense - Automatic biometric identification system (ABIS), Indian national identity certification, UAE entry-exit system (due to the custom of Middle East people, many women usually only show two eyes), mine and some personnel safety management with high manual labor intensity (the fingerprints of these personnel usually wear more seriously), etc. Iris recognition has long been deployed in the civil market, but it has not been successful so far.

The development of iris recognition in the civil market can be traced back to 2015. That year, Fujitsu launched a mobile phone called arrow nx f-04g, which is regarded as the world's first mass-produced mobile phone with iris recognition. In the same year, Intel led the establishment of the world's first iris payment alliance, including Lenovo, decode Dahua and Minsheng Bank. Until the galaxy note 7 came out in 2016, iris recognition officially went to the mainstream market. At that time, the operators regarded iris recognition as a new selling point of mobile phones, hoping to cause the follow-up of other mobile phone manufacturers, leading to the consumption boom of fingerprint recognition and iris recognition.

In contrast, when many users of Samsung S8 reported that they would feel headache and dizziness after using iris recognition, Samsung publicly admitted that "they used iris recognition incorrectlyDon't do harm to the eyes ", which makes consumers have psychological problems with iris recognition applications. Then 3D face recognition on iPhone x became popular, and iris recognition was gradually marginalized. Until last year, Samsung's flagship mobile phone didn't give up the iris recognition function, but it never got the "standing up" of its peers. In 2019, the latest generation of Galaxy S10 was released. After all, Samsung gave up the iris scheme and chose the "fingerprint + face" recognition scheme. The application of iris recognition in mobile phones ended unfortunately.

In addition, the traditional iris imaging system has too many constraints and poor user experience, which also limits its application development in civil terminals. Because the imaging distance of iris recognition is relatively short, usually less than 1 m, the depth of field is small, the field of view is small, and the capture volume is small, the user needs to coordinate to adjust the head and eye posture, and can not image the eyes at the same time, so the recognition speed is slow. At present, the main iris recognition mode is fixed focus mode, and the recognition distance is about 20-35cm. If the lens technology can develop rapidly, the recognition mode will be upgraded to zoom, and the recognition wide angle and distance will be strengthened, which will greatly improve the efficiency of iris recognition.

In terms of price, the cost of iris recognition is relatively high, which also limits the growth of iris market. The main reason is that the cost of iris recognition equipment is high, iris recognition module is not widely used in consumer terminals, the upstream and downstream industrial chain has not formed a large-scale, and the price of a single iris recognition module is higher than that of fingerprint module.

The first year of Chinese Iris market has come!

"2019It's the first year of iris market! "Chen Jianwei, technical director of Shenzhen Hongzhi Technology Co., Ltd., actively expressed in an interview with electronic international business information," on the one hand, the continuous release of policy dividend, the country vigorously promotes the construction of national standard system of biometric identification technology based on the needs of network security and homeland security, and this year, the iris and voice print are listed in the public security The two special projects promoted by the Ministry of science and technology prepare and improve the iris image database for special people nationwide, which is of great benefit to iris manufacturers who provide solutions and hardware equipment. On the other hand, the industry standards related to iris are constantly improved. Domestic iris manufacturers occupy the world's leading level in the field of smart door lock. The civil market of iris recognition will usher in a big explosion with the vigorous development of smart door lock market. "



Chen Jianwei, technical director of Shenzhen Hongzhi Technology Co., Ltd.

according to the survey of international electronic business information, iridian, iritech, Princeton identity, eyelock, etc. have developed earlier in the world, with leading advantages; Although the iris recognition technology in China is developing late, there have also been a number of excellent manufacturers, such as: polyhong photoelectric, Zhongke Hongba, rainbow recognition technology, Hongxing technology, release code Dahua, Kai Hong intelligence, point technology, Siyuan ke an, Tiancheng Sheng and so on. They have been constantly achieving technological breakthroughs in recent years, especially in the advanced and accuracy of the core algorithm. Foreign competitors.

For example, the iris recognition cloud service platform built by Sinotech Hongba and the public security system has been establishedIris database with a population capacity of 20 million, and participated in drafting and leading the revision of the national standard "technical requirements for iris recognition system of information security technology" (GB / t20979-2019); iris biometric ASIC chip "dry core" II, independently developed by rainbow recognition technology, will be mass produced by the end of this year, which marks the solution to the three problems of iris product price, volume and power consumption; A new generation of payment products for biometric identification has been developed and is expected to be released in the second half of this year. Point and surface technology has designed and implemented a variety of in-depth neural network iris recognition algorithms. In the future, the coverage of iris recognition technology in China will be further expanded.

As for when iris recognition will break out in an all-round way, Chen Jianwei believes that it is still necessary to return to the terminal consumer market. First of all, according to the needs of users, iris recognition has met the primary condition of consumer electronics - security, but more added value also needs time to cultivate. In a short time, iris recognition will not become the mainstream of mobile phone terminal recognition technology, and can not replace the fast payment of fingerprint recognition and the use habit of compatible entertainment function of 3D face recognition. Secondly, the construction of ecology. If iris recognition becomes a necessary indicator for banks and government agencies to identify citizenship after the national iris database is established, then mobile phones equipped with iris recognition function will be listed on a large scale, which is a necessary condition for the development of the ecosystem.

The application of iris recognition in intelligent door lock

nowadays, when discussing iris recognition in the field of intelligent door lock, we should first emphasize its security performance. In an interview, Chen said recentlyCCTV exposed the negative news that "none of the 38 smart door locks are completely qualified". All of the 38 locks are fingerprint recognition unlocking functions, which once again attracted consumers' attention to the safety performance of the smart door locks. In fact, at present, fingerprint door locks are easy to be broken. If the technology is upgraded or the cost is increased, most of them can be solved. But once the technology level or production cost of fingerprint lock is improved, the impression of "good quality and low price" will be destroyed, and its market competitive advantage will be greatly reduced. Therefore, iris recognition with high security will be the best solution to ensure the security performance of intelligent door lock.

From a technical point of view, the basic structure of the iris is determined by the inherent genetic genes. It tends to be stable after 8 months of human development and no longer changes since birth. Therefore, the iris is unique and highly stable. In addition, iris also has a very strong biological activity, such as the size of pupil will change with the intensity of light, and there is an unconscious adjustment process when looking at objects, which leads to the hardware device used for iris collection and calibration needs to have the function of living detection. These conditions are the physiological basis of iris as the living detection of biometrics.

In view of the current popular smart door lock market, Zhongke Hongba believes that the key point of door lock is safety, ease of use and long endurance; in general, iris imaging system with long distance, large field of view, large depth of field, non cooperation or less cooperation will be the trend. It is reported that Sinotech Hongba has realized the mass production solution of iris recognition door lock, which is based on the deep optimization on the platform, and the security can be achievedOne millionth of the security level; in terms of ease of use, the recognition distance can be 30-55cm; in terms of long endurance, the 7000 MAH battery can be turned on 18 times a day, which can exceed the endurance of 100 days.

Wuhan rainbow recognition technology focuses on a complete set of iris recognition door lock solutions of "hardware + algorithm". In terms of hardware, Hongzhi technology focuses on the development of self-developed chips. The second generation of dry core ASIC chips will be mass produced by the end of this year. It is reported that the power consumption of the chips is only 100 milliwatts. In the application of smart lock, it has reached 8-9 months of standby (the use time of battery charging once), which is suitable for mobile terminal equipment, smart door lock, safe, safe, etc. In terms of algorithm, rainbow recognition technology has established a special algorithm team, led by two doctoral founders, to develop a special chip ASIC that can be hardwired from the bottom of the algorithm, rather than using general CPU and DSP operation, so as to achieve safer, faster unlocking function and lower power consumption. In addition, Hongzhi technology has also launched its own brand of complete iris lock product - IDL. Initially, it is equivalent to a "product model", which is provided to the lock factory and complete machine factory for research and development, so that the terminal manufacturer can more intuitively experience the security advantages of iris recognition in the field of door lock, and design more personalized intelligent door lock products based on this.

"I think iris is not to replace fingerprint and face, but to promote the advantages and disadvantages of the three technologies to form an era of full biometric technology. Therefore, the current stage is the key period for iris manufacturers to cultivate users' needs, so that more consumers can see that iris shouldThe advantages of using. " "The next step of Hongzhi technology, together with the upstream and downstream of the industrial chain, will first make one or two good hardware products to impress consumers from the perspective of the scheme," Chen Jianwei predicted; In the future, based on the experience of these solutions and core modules, they will be extended to various scenarios and applications. Only when there is differentiation, there will be a good market. Finally, the iris industry chain will be opened to solve the application, scenario, cost and other problems, and iris recognition technology will develop for a long time. "
