In 2020, the outbreak of the epidemic caused the use of health codes in major cities. The health codes are based on real data to identify whether people have directly or indirectly contacted some infected people, so as to determine whether people need to be quarantined and checked. In an interview with the news, the deputy secretary of the Hangzhou Municipal Party Committee said that the judgment of the health code comes from three dimensions: the spatial dimension, the time dimension and the interpersonal dimension. This shows that the generation of the health code makes full use of the user's data. Although the official has not disclosed the details of the data use, it is guessed that the health code will combine the user's interpersonal relationship data, GPS positioning data, telecom operator data, consumption record data, line Scan code location data and other related information, and then judge whether personnel enter or leave high-risk venues. The application of health codes is a typical case of big data technology.
Network service providers use collected user data to predict users' health conditions, making epidemic prevention and control more efficient and accurate. While people enjoy the convenience brought by big data, if network service providers do not use user data in accordance with regulations, it will also cause harassment to users and threaten users' privacy information. 1.

Clausewitz, "On War" Li Xiaolai once mentioned that the word "leek" was never used before writing the book "The Self-cultivation of Leeks", because the definition of the word "leek" was not clarified, and before the definition of a word was clarified, Should not be used casually. Since the concept of big data was proposed, we have widely used "big data" for so many years, so what should be the specific concept of "big data"? In the real world, there are many words that have no official definition, such as "artificial intelligence", and no institution says that what they define is the correct concept of "artificial intelligence". In different eras, people have different definitions of artificial intelligence. In the 1960s, people believed that a computer that could play checkers was artificial intelligence, but now it seems that this statement is obviously unacceptable.
