What is the finger vein technique? What is the difference between it and the fingerprint? Will it replace the fingerprint application? This article will take these questions, combined with the development direction of biometrics, to do some preliminary discussions.
Brief description of finger vein technique
The finger vein recognition technology is derived from research projects at Hitachi Medical Institute. In this project, the researchers found that each person's finger vein images obtained by near-infrared irradiation were different, thus creating conditions for identity authentication based on finger veins. After more than 10 years of optimization and improvement, Hitachi solidified the technology into the finger vein recognition module and promoted it globally. The finger vein ATM machine, the finger vein entry instrument mentioned above, and the finger vein access control and attendance equipment that we use in daily routines are all developed based on the Hitachi finger vein module. As the inventor of this technology, Hitachi also represents the highest level of current global finger vein recognition technology.

The finger vein technique has a significant advantage over traditional biometrics such as fingerprints. The finger vein reading is based on the vein image obtained by using the near-infrared rays to illuminate the finger veins. It is an internal feature of the body that does not leak, so it is not easily extracted like a fingerprint, and there is no accidental scratching of the fingers or damage of the skin during work. The situation that the fingerprint is unrecognizable; the finger vein image requires that blood flow must pass, thus ensuring that the finger vein is in the absolute sense of living body recognition.
Like this technology based on internal body feature recognition and must be living body recognition, we call it the second generation biometric technology. It has the same characteristics as the finger vein, and also includes iris recognition. In customer communication and product promotion, high-end biometric technology products such as veins and irises are often installed in core protection areas and high-level leadership offices, which not only enhance the security level, but also facilitate leadership use and highlight high-end temperament. For senior leaders, the use of finger veins is much closer to traditional fingerprint recognition, and iris recognition needs to scan the eyes, which is easy to create a sense of rejection and a certain degree of fear, so at the high end In the application scenario, the finger vein seems to be easier to promote than the iris.

The finger vein is technically superior to the fingerprint, but its volume is larger than the fingerprint identification device, and the price is higher, so that the finger vein will still appear in the image of the project highlights and selling points in a short time. There are fewer opportunities to encounter batch applications as large as fingerprint identification devices. In addition, fingerprint recognition has gradually evolved from the earliest high security precautions to daily life tools, and the development of mobile phone unlocking, fingerprint locks, etc. is closer to civilian use. The finger veins have to be upgraded and replaced in the near future, and the difficulty is still relatively large. of.
In fact, various biometric technologies have their application characteristics and matching scenarios, which often complement each other. Fingerprint and face recognition Although there is no iris and finger vein at the safety level, the user experience and acceptance are better, and the equipment cost is low. It is suitable for promotion as a biometric technology used in daily work and life. Ma Yun’s face payment is A typical application. Many of our earliest exposure to iris technology are in the blockbuster movie, which means that the high-definition, high-security biometric technology has higher value and added value, and is more suitable for application in scenes with high security requirements. Although it can be used, it is more difficult to promote than common techniques such as fingerprints.
Finger vein application
Although the application of finger vein recognition technology in daily life is still in its infancy, in the field of professional security, more and more users have seen its huge technical advantages and development potential, and many worry about the security level of fingerprint recognition technology. Finger vein recognition technology is used in scenarios where there is not enough or a need for higher specification prevention.
In a provincial bank access control system transformation project, the vault and gun arsenal are the key points of prevention. The user considers that the fingerprint may cause abnormalities such as fraud and recognition rate. For the sake of safety, the whole system adopts finger vein recognition technology and has obtained good effect.
The driving school test system is one of the earliest test systems to introduce fingerprint recognition. At present, not only the fingerprints need to be entered in the theoretical test, but also in some areas, the fingerprint information is required to be checked in the actual operation test. If the driving test system is infiltrated by fingerprint film and fake fingerprints, it not only damages the authority of the issuing authority, but also buryes safety risks for road traffic. It is precisely because of the characteristics of the internal vein characteristics of the finger vein technology that cannot be copied. Some driving schools have evaluated the feasibility of using finger vein replacement fingerprints as the actual operation test identification.
In addition to the high security level of the treasury and prisons, security and border inspection are also important areas for strict requirements for identity authentication. In a security inspection project, a single biometric technology can no longer meet the needs of customers. The leading company in the security industry, Hikvision, has a set of integrations with strong video surveillance technology, a full range of cameras, and high-end biometric technology. SmartIPC, finger vein identification, ID card reading, LCD screen display personnel channel. The project adopts multiple authentication methods such as document identification, biometric identification, video analysis and recognition, etc., to realize identity confirmation, photo capture, photo information, surveillance image superposition, background list comparison, etc., and access control system, security inspection system, video surveillance system. Highly integrated and unified management in the same platform has greatly improved the accuracy and efficiency of security inspection work, and has been recognized and praised by users.

Internet + biometrics
In many integration projects represented by the border inspection channel, we deeply feel that what users really need is not a single biometric technology, but a safer, more convenient and more controllable application environment. Biometric technology is the same as the traditional prevention technology such as alarm, access control and monitoring. It is only the means and tools to solve the problems of users and meet the needs of customers. It is the core goal of the whole system. In the field of public security, biometric identification technologies such as fingerprints and finger veins, and traditional prevention technologies such as access control, alarm, and monitoring, plus unified management of the platform, combined with big data and Internet+, to build a truly safe and convenient prevention and The identification system will be an important development direction for future biometrics and security systems.
In the era of Internet+, when traditional biometrics are combined with cloud computing and big data, it will have a subversive impact on the original technical solutions, promotion models, and even business models. Taking Face++, which has been in the limelight, as an example, the product analyzes face data through a cloud computing platform, greatly expands the sample data, and improves the recognition accuracy. The face recognition rate of the traditional stand-alone mode is 85%. It has risen to nearly 98%, and there are even reports that it has exceeded the human eye recognition rate. At the same time, due to the adoption of the cloud computing method, the application has very low computing power requirements for the front-end device itself, which can greatly reduce the cost of the front-end device, and lays a foundation for the product to enter more application scenarios and form a large-scale application, and forms a “ Optimize the algorithm to improve the accuracy and reduce the cost of a virtuous cycle.
It can be imagined that the model based on cloud computing to improve the reliability of the algorithm and reduce the cost of the front-end device is not only applicable to face recognition, but also applies to many technologies requiring high computing power such as fingerprints, finger veins, and even video intelligent analysis. Biometric technology combined with Internet+ will be further integrated with video intelligent analysis technology, traditional access control and alarm event triggering to form a smarter, more accurate and more distinctive solution to meet users' different scenarios and different security. The level of defense requirements.
Going back to the Hikvision security personnel channel project mentioned earlier, customers have proposed that in addition to the integrated finger vein recognition function, it is also based on the SmartIPC docking Face++ application superimposed on the human channel to form a reference vein and face recognition. High security border check channel solution. The final landing of the program will have a very broad application prospect for both the identification and control of border inspectors and the security and attendance of enterprises.
Conclusion
From the unique discovery of the finger vein, to the invention of the finger vein recognition technology, the maturity, the popularization and application, and the combination of the face recognition technology based on the evolution of cloud computing, we can clearly see the development path of biometric technology from birth to maturity. In the process of biometrics from the ground up to the well-known, the security industry is an important growth environment, creating a lot of application scenarios for the maturity and stability of the basic technology, and promoting the improvement and advancement of technology. On the other hand, the development of Internet + and cloud computing is the big environment of the whole society, which not only affects the development direction of biometric technology, but also affects the development direction of the entire security industry and even the IT industry.
We believe that relying on the development of the Internet environment, focusing on small scenarios that meet the needs of end users, while continuously optimizing the application experience, and effectively improving the security level of key scenarios, biometric technology will certainly achieve more rapid development.
