Abstract: With the rapid development of new-generation information technologies such as big data, cloud computing, and artificial intelligence, data has become a basic strategic resource and key production factor in the digital age. In addition to emphasizing the efficient use of data and maximizing the value of data in the National Fourteenth Five-Year Plan, it is also clear that the protection of data security must be strengthened. This article is based on the data security concept of "identifying data, dynamic protection, sorting out roles, clarifying processes, and precise management and control". It relies on data security label technology with data security level evaluation models and cryptography technology providing basic information support for the security protection of each link in the personal data life cycle. Combined with the object-centric integration, management, and sharing of personal data in the personal data space, this article provides solutions for the efficient use of personal data and security protection.
