Paper Abstract

The development and application of spatial database ultimately create the demand for spatial information security, and access control is our primary concern. The access control requirements for spatial database contain two special aspects: 1) fine-grained; 2) meeting certain conditions, including spatial and non-spatial. In this paper, we propose a view-based mechanism to implement access control functionalities. We firstly present the authorization model for spatial data. Then we thoroughly discuss the definition of various views and their authorization, and explain the advantages and disadvantages of this model. We also provide a reference framework for the view-based access control system, and the components and control flow are explained. Finally, we use a case study to demonstrate the feasibility and effectiveness of view-based authorization model for securing spatial database access.
