A Multi-layer based Access Control Model for GIS Mobile Web Services

This paper proposes a Multi-Layer based Access Control Model for GIS Mobile Web Services. In order to establish access control policy, the proposed access control model assigns policies to each layer, which consists of geospatial features or non-geospatial features. The proposed security model enhances usability by assigning secured layers with policies to users, because a layer can be used as a semantic grouping unit. It also makes complexity of security mechanism lower.
