Legal Improvement of Personal Information Protection in the Era of Big Data in China

In the era of big data, the development of science and technology not only brings economic benefits, but also accelerates the flow of information. The possibility of personal information being illegally collected and used is greatly increased, and the resulting cases are also increasing. The protection of personal information has gradually become a problem that countries need to solve through laws. This paper adopts the method of comparative study to study the legal improvement of personal information protection in China in the era of big data. Firstly, this paper reviews the legislation and countermeasures related to personal information in China and the United States, analyzes and compares the differences in legislative purposes and measures between the two countries in this regard, and then points out that technical barriers in the protection of personal information in China lead to the imbalance of relevant subject status and the lack of industry supervision. It also proposes that China should continue to introduce administrative regulations and other normative documents on the basis of existing laws and increase the autonomy system of big data-related industries.
