面向GIS的角色访问控制模型研究
首发时间:2010-02-05
摘要:基于角色的访问控制模型RBAC实现了用户与访问权限的逻辑分离,降低了授权管理的复杂度,具有较高的可扩展性和灵活性,得到了广泛的应用。但是,RBAC难以适应信息量巨大、信息资源变化频繁的应用系统。GIS以地理空间数据和信息作为研究对象,具有数据量大、结构复杂、关系多样、时态性等特点。本文引入“地图操作角色”概念,探索适合于GIS数据库操作的地理空间数据访问控制模型,并在土地利用规划管理系统中实现。

The Study of Role-based Access Control Model GIS-Oriented
Abstract:Role-based Access Control Model separate user and access authority availably, which cut down authorizing complexity. RBAC is widely applied for its higher expandability and adaptability. However, during the course of the combination of RBAC and GIS, some shortcomings and limitations are exposed, which restrict the application of RBAC to the field of geographical information science. A concept called \"map operation role\" is prompted to realize the authority control of the storage and access of heterogeneous geospatial data. The model is implemented in land-use planning management system effectively.
Keywords: RBAC GIS Land-use Planning Management
