基于任务角色的工作流模糊访问控制模型

A Workflow Fuzzy Access Control Model Based on Task and Role

引入模糊逻辑的思想,在基于任务角色的访问控制模型和工作流执行特点的基础上,提出了基于任务角色的工作流模糊访问控制模型,根据用户的基本信息和历史记录,运用模糊综合评判法计算出执行工作流任务的用户最佳选择,有效地提高了资源的利用率和工作流的执行效率.

The ideal of fuzzy logic is introduced,and a workflow fuzzy access control model based on task and role is put forward,which is based on TRBAC model and the characteristics of workflow performance.According to users fundamental information and history record,the appropriate user is found using the fuzzy synthetic judgement method.The utilization rate of resource and executing efficiency of workflow are improved effectively.
