The epidemic is stronger than the tiger.

A war is going on without gunpowder. Different from the outbreak of SARS in 2003, when the new coronavirus infected pneumonia broke out, the Internet has become the main information platform. Through search engines, information flows, social networks, social media, news clients, people can get real-time epidemic dynamics and epidemic prevention knowledge, as well as know and concern about the situation of people in the epidemic area.

It is noteworthy that the big data that did not appear in 2003 is playing a role in this outbreak.

On January 27, Chen Zhaoxiong, Vice Minister of the Ministry of industry and information technology, presided over the chamber of Commerce for big data expert meeting on epidemic prevention and control, conveyed the spirit of the meeting of the State Council on the joint prevention and control mechanism of pneumonia epidemic caused by new coronavirus infection, and studied and deployed big data to support the work related to epidemic prevention and control.

Chen Zhaoxiong stressed that the epidemic prevention and control work is a very serious political task, which should not be delayed, slackened or sloppy. The communication industry should focus on politics and the overall situation, take active actions and cooperate with each other, give full play to the role of the expert group, establish the mechanism of expert consultation and study and judgment, highlight the scientific, timeliness and legality, and effectively support and serve the joint prevention and control of the epidemic with big data . precise strategy.

Analyze travel information data

Precise help epidemic prevention and control

What if I have been in the same car with the diagnosed patient without knowing? In recent days, the new coronavirus pneumonia confirmed patients with the same journey query tool was launched. As long as users input date, train number and region and other information, they can find the corresponding journey and confirm whether they have walked with the confirmed patients that have been disclosed.

The developer of the query tool is Tong yongao. When he saw the post looking for people, there are confirmed patients on these trains and flights, he realized that it is necessary, but the pictures are not convenient to query, so he thought of using technology to realize fast query.

At 11 oclock on 27 January, his team of eight began operations. At 10:30 p.m., the first version went online. In the circle of friends released at 22:27 that night, Tong yongao wrote: I feel powerless in the face of the epidemic and cant help So spent a day collecting data with a few friends, built a small web page, hoping to be useful.

This is the small web page, which has been visited 35 million times in four days. In order to ensure the authenticity of the data, the information such as the number of people seeking vehicles is manually verified and entered. Fortunately, the peoples Daily has already undertaken part of the work of providing clues and verifying. Tong yongao said that the program will be maintained until the end of the epidemic period, I just do something small in the way I am good at..

Since the new pneumonia epidemic spread, the power of technology has become increasingly prominent.

A few days ago, Baidu company provided the city data named national heat map of Spring Festival transport migration. Although it doesnt seem to have much to do with the virus epidemic, some media have found some useful content from the big data of Baidu migration map.

For example, after inputting Wuhan, it can be seen that from the opening of the Spring Festival on January 10 to the climax of the first stage of the Spring Festival on January 22, the urban passenger flow ranking from Wuhan (the starting place) to all parts of the country has a positive correlation with the number and time of new pneumonia cases found in all parts.

According to the relevant person in charge of Baidu company, the population flow chart during the Spring Festival festival is mainly based on the downloaded geographic location data of Baidu map app and the information that users voluntarily provide for uploading, and summarized and described by combining big data analysis and mining technology (due to the considerable download base, we think these data have a certain degree of credibility). In addition, baidu also made a supplementary explanation for the data privacy issues concerned by users. The data used in the analysis are desensitized data, and all processing links do not involve individual privacy.

From a technical point of view, if the relevant departments and technology companies can use the massive data information of different dimensions, such as map data, aviation data, mobile communication data, e-commerce consumption data, etc., to conduct comprehensive modeling and analysis, they can make major and reasonable decision-making judgments for the epidemic situation. Of course, the premise of all this is that users agree to open, and enterprises are willing to share relevant data.

According to Wang Yukai, a member of the national information technology expert advisory committee and an e-government expert, there is no problem in making full use of the function of big data to strengthen epidemic prevention and control in the current extraordinary period. For example, through the statistical analysis of travel information data, people flow can be precisely prevented. It is a top priority for the whole society to prevent and control the whole epidemic with the help of big data.

Wang Yukai believes that it is not particularly important who provides the information and data. Both the data of the railway department and the data of the Internet companies should be used by the government in a timely manner and contribute to the current epidemic prevention and control. Internet companies hold data in various aspects to varying degrees, especially on health care. These data should be actively shared with the government when the country is in crisis, which can effectively improve the epidemic prevention ability of data.

Using data to track outbreaks

Does not violate personal privacy

In the news 1 + 1 column of CCTV on January 28, Academician Li Lanjuan, a member of the high level expert group of the national health and Health Commission, said Bai Yansong was using big data technology to sort out the life path of the infected, track the contact history of the population, lock the source of infection and close contact with the population, and provide valuable information for epidemic prevention and control.

Li Lanjuan mentioned in the connection that a patient once said that he had no contact history with key epidemic areas, but after big data screening, it was found that he had contacted at least three potential patients from key epidemic areas. It can be seen that big data technology plays an important role in accurately positioning the epidemic transmission path and preventing and controlling the spread of the epidemic through tracking the movement track and establishing the individual relationship map.

This time, we can clearly see that big data has played a very important role in the process of epidemic prevention and control. The mayor of Wuhan said at a press conference that from January 10 to 23, 5 million people flowed out of Wuhan, which is a precise big data. In the interview, Wang Yukai told the Legal Daily that Baidu also analyzed the specific flow of 5 million people, 60% to 70% of them moved to various cities in Hubei, 30% to 40% to all provinces and cities in the country and abroad, so all provinces and cities are very clear about the flow of people in Wuhan, which provides a precise direction for the prevention and control of the epidemic.

Wang Yukai believes that with the spread of the epidemic, big data plays an increasingly important role. Big data can help to analyze the peak period of epidemic spread and whether there is secondary infection among personnel, which plays a strong role in prevention. Control the flow of personnel through big data, which is a further prevention of using big data.

For example, Beijings decision to stop inter provincial road traffic in an all-round way is based on big data analysis, while controlling the railway. However, there is no control over civil aviation and high-speed rail, because these two methods can carry out strict temperature detection and travel direction control. The loss caused by all traffic interruptions to economic and social development is immeasurable, so we should try to find a balance between risk and safety, and the way to find this balance is to rely on accurate big data. Wang Yukai said.

Previously, a picture circulated on the Internet showed that operators in a province tried to use big data portraits to help health departments locate potential epidemic risks, among which the number of users roaming from Wuhan to a province and a province to Wuhan was clear at a glance.

In the view of the insiders, based on roaming data, combined with the identity information of the real name number system, theoretically, it can track and prevent and control the overflowing personnel in the epidemic area, thereby reducing or even blocking the spread of the epidemic. As long as users dont throw away their phones and turn them off, they can be tracked. There is the problem of user privacy protection. Operators naturally cooperate with regulatory authorities to sort out and analyze, and make use of user big data within the framework of relevant laws and regulations.

In this regard, there are also comments on the issue of privacy protection. In the interview, Liu Deliang, Professor of Law School of Beijing Normal University and director of Asia Pacific Network Law Research Center, believed that at present, a wrong concept of privacy is to treat personal information as personal privacy. As a result, everyone is talking about privacy, but everyone is talking about privacy in a different language.

This leads to the consequences of the uncertainty of privacy. In the sense of law, privacy is protected by the right of privacy. A basic function of law in establishing rights is to divide and stop disputes. The boundary of rights is also the boundary of freedom. Within the scope permitted by law, it can not be violated by others. Similarly, the law should be known to the public when establishing the right boundary. The law must protect the rights and interests of the obligee and the public. At present, the definition of the right to privacy depends on the individual, which is not in line with the standards established by law. Liu said.

Establish smooth data channel

Improve the overall prevention and control ability

No one is an island in front of the epidemic. Compared with SARS 17 years ago, the role of the Internet, especially big data, is particularly obvious in the process of fighting the epidemic. The latest epidemic information, all kinds of experts questions and answers, patients help and certification on social media, multi platform epidemic prevention live broadcast, and the common peoples online first-line lead to help each other. We are no longer trapped in the information black hole atomically, but through the network to get help, support and comfort in the virtual world.

In fact, from the perspective of prevention and control of pneumonia, big data has played a corresponding role, but there are still many areas to be explored. If there is a next outbreak, what can big data do, what can science and technology do, and what can big data defense do?

In Wang Yukais view, it is very urgent to strengthen data sharing. There is a need to get through data between provinces and cities, between local and local governments, between enterprises and governments, and between domestic and international, and to establish a smooth data channel around the data sharing of epidemic prevention and control. After the channel is built, it will be able to improve the overall prevention and control capability of the whole country, and will not fight separately.

At the same time, Wang Yukai also pointed out that at present, there is no personal information protection law in China, and the system and norms of personal information protection are not detailed enough. Therefore, there are also a few abuses of personal information. In this extraordinary period, the first is to use big data for epidemic prevention, and the second is to protect personal privacy as much as possible. In the process of using big data, personal privacy should be taken into account to the largest extent, and the abuse of personal information should be avoided. These two need to be weighed, and consideration of the overall situation of defense is the primary consideration.

Big data is very powerful and can play its own role in early warning, governance, follow-up treatment and other processes. According to Liu Deliang, from the perspective of this epidemic situation, the early-warning function of big data has not been paid enough attention, leading to such a rapid spread of the epidemic and failing to raise the awareness of social vigilance in time.

At the same time, big data can also play a role in the governance process. In the current process, through big data analysis, we can accurately analyze the spread of the epidemic situation, targeted governance. In the follow-up treatment process, big data can also play its own role. We cannot limit its function to the analysis of current epidemic situation. Big data can even help us prevent future unknowable outbreaks. On the other hand, the current legislation should also be updated in time to actively promote the development of big data. Liu said.

It is worth noting that in the past period of time, several Internet companies have provided a large number of data support to relevant departments through their own data and technical capabilities, and made great contributions to the screening, tracking, control and isolation of infectious sources (personnel).

However, there are also comments on whether such data sharing behavior is legitimate? There is no exception in the network security law. Can we rely on the exception of consent in the national standard personal information security code to resist possible legal disputes in the future?

Data sharing behavior needs to be further differentiated and cannot be generalized. In times of national crisis, if these data are related to epidemic prevention, I dont think its against the law, which is an extraordinary measure in an extraordinary period. However, if Internet companies use these data as a profit-making map for commercial application, they will not have legitimacy. Wang Yukai said.

Wang Yukai told Legal Daily that the national security law and the national information security law also have preliminary provisions on personal information security, but they are far from enough. Before the introduction of the personal information protection law, the regulation of personal information was still based on the network information security law, but its provisions were not detailed and there were many fuzzy areas. The legislation of personal information protection law has also been incorporated into the national legislative planning. Before the introduction of the formal law, the protection of personal information in the national security law and network information security law should be used for adjustment, but if there are problems beyond the scope of the legal provisions, they should be made up by administrative measures or other measures. At the same time, it also warns us to further improve laws and regulations. Big data industry, data sharing behavior and even artificial intelligence industry are difficult to develop if defined according to the traditional paranoid concept of privacy. Therefore, I believe that as long as there is no privacy in the legal sense, data sharing behavior has legitimacy. Liu said that the law should first reflect the reality, and then promote economic and social development. The Enlightenment of this epidemic is that we need to change our ideas, establish a correct concept of privacy, and abandon the wrong idea that personal information is equal to personal privacy. While paying attention to the protection of privacy in the legal sense, we should also prevent the abuse of personal information and do a good job in the follow-up prevention and control.
