摘要
以现代企业应用需求为背景,提出一种基于任务角色访问控制的数字权限管理模型(Task-role expended digital rights management,TR-EDRM).该模型建立在任务分类的基础上,采用"任务"和"角色"相结合的思想,解决了权限部分继承问题,适用于既存在工作流又存在非工作流的企业环境,提高了企业数字内容管理的安全性、灵活性和透明性.
A task-role-based access control model, called the TR-EDRM（Task-mle expended digital rights management model）, is proposed to meet the demand of modem enterprise application. The model is based on the task classification. It adopts task-and-role-combined approach and solves the problem of role hierarchy partial inheritance. The model can be applied to workflow and non-workflow tasks. The security, flexibility and transparence of enterprise digital content management can be improved as a result.
