介绍了基于Petri网工作流的动态访问控制的概念。文中描述的方法可把访问控制矩阵从二维扩展到三维,并使之动态化,从而降低数据滥用的风险。
The concept of dynamic access control based on Petri net workflow is introduced. The approach described in this paper extends the access control matrix from two dimensions to three dimensions and makes it dynamic, reducing the risk of data abuse.
