What is the prospect of "palmprint reading" in WeChat internal palmprint payment?

According to recent media reports, WeChat Pay is testing a new payment function called "swipe payment". Users can directly experience the use of the palm-brushing payment function on the face brushing device. Once the news was exposed, it immediately caused a heated discussion on the Internet.

In fact, the concept of palmprint recognition was put forward as early as the late19th century. According to the definition, palmprint refers to the palm image from the end of the finger to the wrist. Many of these features can be used for identity recognition, such as main lines, wrinkles, fine textures, ridge ends, bifurcation points and so on. By comparing the collected palmprint with the palmprint information in the palmprint database, the identity information can be verified, and then the program operations such as payment, access and so on can be carried out. Previously, some domestic and foreign enterprises have also developed and applied related products in order to make a breakthrough and development in the field of biometrics.

With the continuous development and application of biometric technology, people have higher and higher requirements for biometric technology, and the further development and promotion of palmprint recognition technology has also been put on the agenda. Then, based on the actual situation and future development, what is the development prospect of palmprint recognition technology?

Necessity of normalization protection of epidemic situation

Since the COVID-19 epidemic began in 2020, the global epidemic has not stopped. According to the "Guiding Opinions on Doing a Good Job in the Normalization of COVID-19 Epidemic Prevention and Control" issued by the State Council Joint Prevention and Control Mechanism, combined with the recent recurrence of epidemic situation, fighting the epidemic situation is undoubtedly a "protracted war" with a long time and a wide span.

Coronavirus pneumonia-19 virus has a long survival time and is highly contagious. Some biometric methods widely used now will have certain risks in the process of epidemic prevention. For example, fingerprint recognition needs direct human-computer contact, and some face recognition needs to reveal facial organs, which undoubtedly greatly increases the risk of infection.

Due to the rapid development of biometric technology in recent years, palmprint recognition has been completely equipped with no direct contact between man and machine, no need to reveal facial organs, just show your palm in front of the camera and collect it from a distance by the camera, thus completing identity comparison and verification. It can not only reduce the risk of infection and epidemic diseases, but also contribute to the implementation of epidemic prevention work. It still has high use value in hospitals, laboratories and other places that need "less contact and no contact".

People's demand for higher privacy technology

Nowadays, fingerprint recognition and face recognition are mainly promoted, which greatly facilitates people's work and life, but also exposes some problems. Because of its particularity, fingerprint identification is more in line with people's requirements for privacy protection, but its application scope is narrower than face recognition. Face recognition is more widely used than fingerprint recognition, but face is the only personal core privacy information that can be collected without users' initiative, so it is extremely sensitive in implementation and use. At the "3 15" party on 202 1, the chaos of face information being used by illegal businesses fully exposed the seriousness of this problem.

Palmprint is not only easy to collect, but also widely applicable, and it needs the active cooperation of users, so it is difficult to be collected as easily as face information, which is more in line with the needs of modern society.

Social demand for stronger security

In 2020, China Judgment Document Network published the criminal ruling of the second instance of Quzhou Intermediate People's Court in Zhejiang Province (hereinafter referred to as the "ruling"), which revealed a case in which a criminal gang used software to make a photo of a citizen's head into a 3D head, and "cheated" Alipay's face recognition to register a new user as "bonus hunter". The forgery of related face and fingerprint information is also common, which not only attracts the attention of the society, but also makes the society have higher requirements for the security of biometric technology.

Palmprint recognition technology has a higher safety factor. Zhong Dexing, Ph.D. and Associate Professor of Xi Jiaotong University, published a research paper entitled "Research Progress of Palmprint Recognition" in May, 20 19. It is mentioned in the paper that palmprint recognition technology has many unique advantages compared with other biometric technologies, such as texture features with high recognition, such as main lines, wrinkles, ridges and bifurcation points. The shape of palmprint is mainly controlled by genes. Even if the epidermis falls off for special reasons, the new lines still maintain the original structure. Therefore, palmprint feature recognition has the advantages of rich texture features, high security and stability.

In addition, at present, palmprint recognition technology is not only a technology to obtain palmprint information, but also generally combines palmprint vein recognition technology to obtain vein information under palmprint skin through infrared camera. Therefore, unlike fingerprints, face information and other information that is easy to forge and crack, palmprint information is richer and more complex, and it is more difficult for criminals to use, which is a solution to greatly improve technical security at present.

Constraints on future development

Although palmprint recognition has many unique advantages that other biometric technologies do not have, it is likely to become the main direction of biometric technology in the future. However, the author believes that the development of this technology will still have its own "constraints."

Although the palmprint information is varied, rich and complex, and the requirements for acquisition equipment are not high, it is indistinguishable from the naked eye in the overall shape, and it relies heavily on artificial intelligence algorithms for recognition. The extraction of palmprint features is the most critical part in palmprint recognition, and the quality of recognition algorithm largely determines the speed and efficiency of recognition. With the increase of content in the database, the difficulty of palmprint recognition will naturally increase. How to continuously refine the features, further improve the accuracy and reduce the false recognition rate is a difficult point that palmprint recognition technology needs to overcome in the future.

At the same time, due to the popularity and use of popular "face recognition" and "fingerprint recognition", the technology is constantly developing and evolving. As a solution to the above technical defects, palmprint recognition technology started late, and the experience technology in this field is not mature enough. However, the immaturity of technology means that palmprint recognition is probably still a small-scale trial operation technology at present. If it is to be officially popularized, I am afraid it will take more time and technology accumulation.

Compared with the problems of palmprint recognition technology itself, the possible data leakage can not be underestimated. In recent years, user information, data and other private information have been leaked frequently. In the face of the severe market environment, the state has enacted the Personal Information Protection Law and the Data Security Law at the legal and regulatory level, requiring the Internet platform and financial institutions to "directly disconnect" from personal information at the industry supervision level. However, in order to protect data security and prevent information leakage, it is not enough to rely solely on legal provisions and management systems. The continuous iterative updating of network security technology is the most direct and effective method to reduce the risk of leakage. In this era of biometric technology, how to maintain the security of data is also an eternal topic.

There is still a long way to go.

The development prospect of palmprint recognition technology is very good, but due to the relative immaturity of technology and the current market situation, palmprint recognition technology still has a long way to go before it is officially implemented. However, more convenient and safer technology has always been the biggest consideration for human beings to pursue technological progress. I believe that one day, palmprint recognition technology will leave a strong impression on human life in the future.
