[Expert point of view] Professor Zheng Fang of Tsinghua University: How to ensure that the network identity in the digital economy is safe?

Focusing on the hot topic of network security in the digital economy, the "Information Security Research" magazine and Xinhuanet client have conducted a series of interviews. The experts in this issue are Professor Zheng Fang, director of the Institute of Hearing Intelligence Research Center of the Editorial Committee of the Tsinghua University of the Tsinghua University. Below, Professor Zheng analyzed and interpreted how the network identity security in the digital economy was ensured.

Zheng Fang, Director of the Institute of Hearing Intelligence Research Center of Tsinghua University: "The digital economy is now unprecedented, and the digital identity is a very important guarantee in the digital economy. The identity authentication of the number should have two different considerations, one That is to say, a kind of physical space, one in this case of supervision, based on the factual certification. It is divided into three types, such as knowing the so -called real name, or password. The second is what you hold. Speaking of documents, or U -Shield. The third is what is, my biological characteristics are real. If there is a supervision of the physical space, this is no problem, but you will find that there is a problem in the digital space, so I will just be Proposal to another, consider this certification in the sense of behavior in the digital space. Then it considers the other three attributes. The first is the place where you are in the current situation. Whether you want to make your wish, whether it is your true will, but also a true manifestation of a will in the present situation. Another is what you do. In the current situation, your real behavior. Consider the integration to consider That is, in the digital space, if I have to consider this identity certification, we should conduct a behavioral certification in the sense of behavior based on these attributes. Reality.

In fact, the problem of counterfeiting will definitely exist. There are several problems. I have to solve it technically. The first is 'one -person certificate'. This 'certificate' with me and me must be consistent, and the accuracy of recognition must be high. Second, it is not easy to forge. If it is a computer and artificial intelligence forgery, forgery videos, then you can identify it. The third is true will. Of course, from the national level, you have to consider traceability. If I break the law in the network space, you can find it.

This certificate we currently use is more based on the second generation (identity) certificate, which is held. Therefore, it is difficult to play a role in digital economy and digital space. So we urgently need a certification method that can adapt to the digital economy and digital space. I think there are several aspects to do. First, laws and regulations must be improved. The second is to indicate, codes, and cannot leak users' privacy. Third, I think it should be a complete, safe, and classified identity certification system. I think these three things are actually a relatively large infrastructure project. You can say that this upgrade is a process of natural development. You can also say that it is a need, and even it must be done. Because in the digital space, if there is no such system, you cannot guarantee that the activity in me is legal and I am legal, so it must do it. In a sense, the necessity is very important. "
