【Purposes】 In this paper, research on various stages of the data life cycle and various security governance technologies has been conducted to achieve data security governance progress by searching and analyzing related technical literatures. 【Motheds】 First, the importance of strengthening research on data security governance is analyzed by introducing the status quo of data security governance. Second, the theory of the whole data life cycle is expounded in detail, and the different stages of the data life cycle are given. Third, the data security governance technologies and their applications in different life cycle stages such as data preparation, use, storage, and destruction are systematicalhy summarized. At last, the challenges and future research directions of data security governance are analyzed and prospected. 【Conclusions】 Strengthening data security governance is of great significance, whether for the privacy protection of personal information, or for the development of the data industry itself, or even for the information security of the country.
