Research on key technologies of privacy protection in big data computing environment

In terms of big data computing, it is mainly based on data sharing, which includes various information technologies. Although it provides corresponding assistance for people to solve problems, there are also privacy breaches. In order to improve the security of privacy, people have carried out corresponding encryption, authentication, authorisation and other operations on privacy, but the problem of information leakage has not been effectively solved, posing a threat to people’s privacy security. In big data computing, there are relatively many factors that lead to privacy breaches. In order to ensure people’s privacy and security, this article conducts research on key technologies of privacy protection based on previous research by collecting a large amount of literature.
