Should the data of ＂health code＂ be deleted？ The proposal of Wenzhou representative attracted a debate.

　　Wenzhou Net News The ongoing two national conferences have brought public data security into the public eye. Hu Chengzhong, deputy to the National People’s Congress and chairman of the board of directors of Delixi Group, suggested that with the epidemic prevention and control entering a new stage of "Class B and B management", the "health code" has been completely stopped, and the relevant data collected by the "health code" should be deleted within a limited time to reassure the people.

　　In Wenzhou, everyone is most familiar with the "Wenzhou Epidemic Prevention Code". It is equivalent to the merger of "health code" and travel card, and was officially launched on November 1, 2021. Relevant reports show that the number of users of Wenzhou Epidemic Prevention Code reached 8.96 million only two months after it was launched, and by April 2022, the number of users reached 14.39 million, and the number of bright codes per day reached more than 18 million.

　　In the prevention and control of epidemic situation, "health code" played a great role and became a highlight of China’s anti-epidemic experience. At present, where should the massive data behind the "health code" go?

　　Completely delete the square

　　Wang Xianming, deputy dean and professor of the School of Data Science and Artificial Intelligence of Wenzhou Institute of Technology, clearly understands his point of view: absolutely support, and the "health code" data should be completely deleted.

　　He believes that on the one hand, from the perspective of the necessity of data retention, epidemic prevention and control has entered the "Class B B Management", and there is no reason to use these data again, so there is no need to keep them. On the other hand, data storage is bound to have security risks, although it depends on where the data exists. Is the platform reliable? But this only shows that the security risk of data leakage is big or small, and it can’t completely avoid the risk.

　　"The importance of personal data is self-evident, so when deleting it, we should pay more attention to the security of the data during the destruction process, and ensure that the data is completely destroyed." Wang Xianming said.

　　Also supporting the positive view is a professional who has been fighting in the front line of epidemic prevention for three years. He believes that for the traceability work, collecting personal data in epidemic prevention and control is to quickly trace the trajectory of infected people in the past 7 days and 14 days in the event of an epidemic. This supports the epidemiological investigation to the maximum extent. Through the data, we can basically judge where the infected people are infected, and provide reference for the subsequent delineation of medium and high-risk areas. However, the professional also pointed out that after the epidemic entered a new stage, it is no longer necessary to trace the source as before, so it is no longer necessary to rely on these historical data at present. "After all, this is the transfer of personal privacy made by the public in order to cooperate with the overall situation of epidemic prevention."

　　What do ordinary citizens think? Let’s see what the supporters in the positive camp say — —

　　Citizen Li Tao: No suggestion, delete it immediately. The mission of "health code" has been completed, and relevant data should be completely deleted.

　　Citizen Qiao Qiao: I am a 2018 undergraduate student. I was often locked in school from my sophomore year until graduation. During the period of school closure, every day, in addition to doing nucleic acid, the "health code" was checked. Now when I see the "health code", I will think of that painful memory, especially hoping to completely delete the "health code" and related data.

　　Natural extinction of the opposing side

　　A data engineer, who asked not to be named, believes that the key issue is not whether the data should be saved, but what can be done to make the data more secure.

　　In this regard, Xu Gang, Dean of the School of Artificial Intelligence of Zhejiang Security Vocational and Technical College, also said that it is not easy to generate massive data on specific topics, and it is of high value in professional fields. Massive data should be preserved for a long time, and it will be better through natural extinction. He explained that theoretically, every kind of data has a life cycle, which is divided into collection — Handling — Transmission — Exchange — Six stages of destruction. In the short term, it is necessary to consider that the destruction needs to be based on certain policies, regulations and technical means, and not only will there be risks that cannot be traced back, but also corresponding costs and expenses will be incurred. However, natural extinction, such as expired batch destruction, storage equipment scrapping, natural disaster destruction and other factors, is conducive to the long-term reuse of data, especially the epidemic data can be used for long-term research on citizens’ health, epidemic spread theory, optimization methods of epidemic prevention measures, non-compliance behavior during the epidemic, etc. Of course, it is necessary to strictly ensure data security in this process.

　　There are also many citizens’ voices in the anti-party camp — —

　　Netizen "Wendy": As long as it is not leaked, the data can be kept reasonably, and it doesn’t matter if it is not deleted. In case of special circumstances in the future, these data can be used as historical situations for analysis, which may play an emergency role.

　　Citizen Chen Xi: I remember that many people were sending friends to commemorate the trip card when it was off the line. Although there were countless "health code" checks and negative nucleic acid certificates during the epidemic, there were still many warm moments during the epidemic. I hope to keep the "health code" and the data inside, which can be regarded as a commemoration of this special period.
