基于工作流任务状态的访问权限分配模型

An Access Privilege Control Model Based on Workflow Task Status

权限的分配是工作流系统访问控制中的核心问题。本文以任务状态为基础,用二维矩阵描述角色与任务、任务与状态、状态与权限之间的关系,并利用关系运算计算给定时刻角色、任务和权限之间的关系,实现了对角色权限的动态分配,提高了数据访问的安全性。

Authorization is a key problem in workflow access control. Based on the status of tasks, the relationships between roles and tasks, tasks and status, and status and privileges are depicted with a two-dimensional matrix. Using the table of database to calculate the relationship between the role, task and privilege, it can dynamically distribute privileges and improve the security of data access.
