摘要
目的:构造一种能够保障信息共享安全的医院信息管理访问控制模块。方法:比较几种常用的访问控制模型,分析RBAC模型在医院信息环境下遇到的问题。结果:在基于角色的访问控制(RBAC)模型的基础上提出基于数据空间的访问控制方法。结论:基于数据空间的访问控制方法能够减少空间消耗,维护数据一致性,更适合医院管理信息系统使用。
Objective To present a solution of the hospital information management access control for more secure information sharing. Methods Several commonly used access control models were compared. Some problems of the RBAC model were analyzed in the hospital information circumstances. Results A solution of space-based data access control was presented on the base of the role-based access control (RBAC) module. Conclusion The space-based data access control method can reduce space consumption and maintain data consistency, which is more suitable for the use of the hospital management information system.
