A dynamic data access control model supporting multi-link transfer and multi-level inheritance

Abstract

Under the background of digital transformation, all kinds of personnel often carry out data analysis and data product development through remote terminals. Once the end user has obtained the data access rights, the middle platform cannot limit the end user's data viewing and copying behavior. However, the current protection measures can only achieve static access control and internal circulation protection, and cannot extend the control and protection of user access behavior. In this paper, a dynamic data access control model supporting multi-link transfer and multi-level inheritance is proposed, and the technical characteristics and model framework of the model are introduced in detail. At the same time, the flow of access control, the dynamic change of permissions, the transfer and inheritance of permissions under tree rules are given in a specific scenario. Finally, the experimental analysis of the model proves that the model can realize the dynamic security protection and fine-grained access control of terminal data.
