| 中文摘要 | Access control is very important for database management systems. Although several access control models have been proposed for geographical maps, most of them are based on the concept of authorization window. If there are many complex authorizations, we have to define many windows and the processing of evaluation will be time-consuming. This paper presents a new access control model, which supports authorization on map layers. This model also supports both positive and negative authorizations, time constraint and so on. In order to compose a role's authorizations in several layers, Multicolor Combination Theory is defined here. Then we can overlay the authorization layers to map layers in authorization evaluation, which is more efficient. At last some propagation rules are defined to makes authorization simpler and more flexible. abstract environment. © 2012 Springer-Verlag Berlin Heidelberg. |
