A Secured Framework for Geographical Information Applications on Web

Current geographical information applications increasingly require managing spatial data through the Web. Users of geographical information application need not only to display the spatial data but also to interactively modify them. As a result, the security risks that face geographical information applications are also increasing. In this paper, a secured framework is proposed. The proposed framework's goal is, providing a fine grained access control to web-based geographic information applications. A case study is finally applied to prove the proposed framework feasibility and effectiveness. Keywords—spatial data; geographic information systems; access control; authorization
