Haixin Sheng Dr. Sun Qingnan: public recognition of biometrics

On October 27, "2016 Mobile Smart Terminal Summit" hosted by China Information and Communication Research Institute under the guidance of Ministry of Industry and Information Technology and hosted by the Mobile Intelligent Terminal Technology Innovation and Industry Alliance was held in Beijing. At the Fifth China Biometric Industry Innovation Forum on October 28, Sun Qingnan, executive vice president of Beijing Haixin Zhi Sheng Technology Co., Ltd., delivered a speech entitled "Public Cognition of Biometrics".

The content is as follows:

Recently, in various media, including Weibo and WeChat circle of friends, you can often hear some voices. As a newly emerging technology, biometrics technology has entered the public field of vision. As we try new things, there may be differences A variety of different voices came out. Some may be misunderstood, others may be questioned. An author named sweetjohnhu posted an article on Tiger Snooze online on September 25 this year, "Can Face Recognition Technology really prove that" you are you "? "As a practitioner with more than 10 years of experience in the information security industry, the author hopes to explore from an information security perspective why we can not remotely identify people using the face recognition technology on the Internet. We can see that the author is completely Standing in opposition to face recognition technology, he believes that the use of face technology on the Internet is problematic in terms of information security.

The following brief introduction to the core of the article: First, the author believes that online identification is a serious information security issues. For example, the author said that Korean ID cards are also used online. As a result, a large number of personal ID cards stored in banking institutions have been hacked by 80% of their ID numbers and personal privacy information, further causing the Korean ID card system to face Reversal of the situation.

Second, face recognition technology lacks a theoretical basis. Without a credible theory of whether two people's faces must be similar or dissimilar, the author believes that fingerprinting technology is legally based and recognized. Relying on the ID card + fingerprint way to unify people under the line, this is the only solution, rather than relying on face recognition.

Third, the technical feasibility of online face recognition. Face recognition is not a technique that has a clear conclusion to the wrong, but gives a probabilistic conclusion of the similarity. At the same time, large-scale use may face resource problems, which can easily be replayed without live testing. Difficult to collect face data, based on the public security population offline collection lines, online use, who will ensure that the information base is not a security issue.


Fourth, online face recognition anti-attack problem. The most important point is that biological characteristics are innate and can not be replaced. After the password stored in the database is lost, there is a possibility of replacement, and other passwords can be used later. Once the human biological characteristics have been stolen, the loss is irreparable. Online application of face recognition, front-end acquisition of human face will use live detection technology, but now there are some new technologies to crack the existing live detection technology. For example, 3D modeling can be real-time synthesis of live detection need to detect movements and facial expressions, which can easily break most of the existing biometric detection programs. If this is a good technology, why not a large number of developed countries online for identification.

Fifth, privacy issues. The biometrics can not be changed. Failure to meet the requirements of a general access control mechanism for periodically changing the credentials of a credential to reduce risk is not a suitable choice for large-scale identification.

The author at the end of the article posed a question: "Who repeated speculation behind, what is the intention?

After reading this article, my biggest impression is that Haixin has been a company that has been developing for many years in the market of biometrics industry. There are many businesses that are developing together in the field of biometrics. As we promote in the market When biometrics, we have the obligation to make some correct guidance and explanation to the public about the doubts and confusion caused by technology.

In fact, many media reports can be seen similar to the article just described in the article, but most of the fragmented system. To briefly summarize, the public's concerns are mainly included in the following aspects:

1. Biometric storage security. Personally, I think this is primarily a matter of information security and should not be the primary responsibility holder for biometric technology providers. However, the unchangeability of biometrics can not afford the consequences of the loss. This issue is more important. I will discuss and analyze it later.

2. Biometric anti-attack ability. Including some information security attacks, such as replay attacks; and live detection attacks on the implementation of existing life detection technologies.

3. The accuracy of biometric results is credible. The accuracy of biometrics to what extent? Whether to get the real industry applications and end-user recognition. When we use biometrics, no matter what kind of biometrics, what kind of things I can do, I do well, what kind of things I'm doing now, may be good in the future can do. Once responsibility issues arise due to biometric results, who will assume responsibility, I think these are issues that we need to think hard about.
