Privacy Security Status and Countermeasures in the Era of Big Data

Big data is a data set which contains a lot of information and has high value. In recent years, big data technology is gradually popularized and applied, which brings great convenience to people. But it also leads to many problems, one of which is the hidden danger of privacy leakage. The purpose of this paper is to find the possible causes of privacy leakage. Based on the research results of others, this study collected the data through the Internet and conducted some investigations. It can be concluded that there are three main reasons leading to big data privacy problems. First, individuals lack privacy protection awareness and awareness of the harm of privacy leakage. Second, enterprises lack legal awareness, do not protect the user's privacy, and even intentionally violate the law to intercept the user's privacy information. Third, with the development of data industry, government is required to update the privacy protection laws in time. Legal Research on how to protect users' privacy in big data has also been ignored.
