Personal Privacy Protection in Big Data Environment under the New Coronavirus Situation

Abstract

In early 2020, a massive outbreak of a new coronavirus pneumonia swept across the globe. Governments quickly moved to detect and track and isolate patients and doctors and nurses to effectively prevent the spread of virus and protect the safety of healthy people. Tracking personal trajectories, contact surfaces and other information by means of technology can help us quickly detect the close contacts of the virus. But these scattered data are aggregating together, which is the data of citizens' personal privacy. Once the data are used by malicious elements, it will cause incalculable economic losses and even public crises. Therefore, we must pay close attention to the protection of personal privacy. This paper first introduces the measures adopted by various countries in the world to fight against the epidemic situation, and discusses the problems and risks faced by them. Then, the mature privacy protection technology is analyzed. Finally, the research direction of the privacy protection stage during the epidemic period is proposed.
