Abstract Today’s society is a digital society, all data can be stored digitally, which leads to the explosion of data growth. However, the security storage of cloud data is the primary problem that restricts the development of cloud storage. Malicious hackers, software and hardware vulnerabilities and so on will pose a serious threat to users’ data stored in the cloud. This paper combines the typical big data system technical framework and builds the big data security technical framework around the security requirements of big data. Under this framework, the research status of key technologies of big data security is systematically summarized from multiple aspects, including the main security mechanisms involved in the technical framework of big data system. Finally, the core problems and development trends of big data security technology to be solved are summarized.
