What do you know about vein identification technology?

On December 24, 2018, the China Payment and Clearing Association announced the "2018 Mobile Payment User Survey Report." The report shows that only 4.2% of users understand finger vein recognition, and vein recognition is a technology that is not known in biometrics.

What is vein recognition technology?

Vein recognition is a type of biometric identification. One way of the vein recognition system is to obtain a personal vein distribution map through a vein recognition instrument, extracting feature values ​​from a vein distribution map according to a dedicated comparison algorithm, and another method to obtain an image of a finger, a palm, a dorsal vein of the hand through an infrared CCD camera, and a vein. The digital image is stored in a computer system to implement eigenvalue storage. In the case of vein comparison, the vein map is taken in real time, and the advanced image filtering, image binarization and refinement methods are used to extract the features of the digital image, and the complex matching algorithm is used to match the vein characteristic value stored in the host to match the individual. Identification, identification.

Technical principle of vein recognition technology

Vein recognition technology mainly uses the structure of venous blood vessels for identification. Since the vein pattern contains a large amount of characteristic information, it can be used as an object of verification. The principle of palm vein recognition is also to use venous angiography with different absorption characteristics of specific wavelengths of infrared light between veins and muscles and osteophytes. The principle is the same as palm vein recognition. Since the palm is thick, infrared light is usually not transmitted, so reflection angiography can only be used. Infrared light is irradiated on the back of the hand, and the part where the vein is absorbed absorbs the infrared light to reflect the darkness, and the muscle and the bone part reflect strongly, thereby realizing the contrast of the vein. And because the vein pattern is difficult to be forged inside the human body, it has a very high reliability and safety.

What is the application prospect of vein recognition technology?

At present, there are two main types of vein recognition technology, namely finger vein and palm vein. The former is highly safe and extremely convenient. The latter is more hygienic and more acceptable because of its non-contact collection of information. The rate of false recognition and rejection of palm veins is also lower than other biometric technologies.

At present, the palm vein recognition system has become the basic equipment of ATM systems in various banks in Japan, and its application in Taiwan has gradually diversified, from basic access control systems to intelligent surveillance combined with RFID (radio frequency identification). .

What do you know about vein identification technology?

At present, finger vein recognition technology is used in China to build digital campuses. This technology is used to manage the entry and exit of student residences and teaching buildings, and even more detailed personal information management. Without the use of cards, the management and use of educational system facilities have become very well-organized, and the finger vein recognition technology also has a major guarantee for the fairness of the college entrance examination. According to the information available, as early as 2014, the Inner Mongolia Autonomous Region Education Admissions Examination Center issued an "open letter to the candidates for the 2014 college entrance examination candidates" through the Inner Mongolia Admissions Test Information Network. In the anti-cheating measures for the college entrance examination, " A device that refers to a vein collector. Let the "gunner" take the test into a past tense. Guangzhou Baiyun District to the ear of the Bureau of the veins real-name system certification system has been launched, a total of 223 sets of finger vein terminal equipment covering the entire district 22 towns and 76 residence permits.

The advantages highlight why the penetration rate is low and outrageous?

According to the "2019-2023 China Market Research on Market Statistics and Future Development Prospects of the Palm vein Recognition Industry", although the market size of the vein identification industry in China has maintained a growth rate of more than 35%, as of 2018, the market size of the industry remains Only 960 million yuan. The main reason for this situation is that it is still in the vein identification technology itself.

As a low-level recognition technology, vein recognition is embedded in different categories, especially consumer electronics products with a wide range of consumer groups, such as faces and fingerprints embedded in mobile phones. That is to achieve multi-modal applications.

However, because the collection method is limited by its own characteristics, the product is difficult to miniaturize, and the finger vein recognition is not highly integrated into mobile terminals such as mobile phones, not to mention the palm vein recognition technology. Therefore, it is unbelievable that the current vein identification is low in market penetration.

Conclusion

Compared with developed countries such as Japan, the penetration rate of vein recognition in China is still very low, but there is a very large room for growth in the future. With the continuous development of technology, the integration of various biometric technologies will become more mature. Biometric products such as finger vein recognition will be more intelligent, comprehensive and convenient, and will be more secure while being more secure. Application to promote further market growth. I believe that the number of companies in the vein identification industry will increase rapidly in the future. Our life and property security will receive a new guarantee.
