- W2787392661 abstract "Spatial data stored in distributed geographic repositories need to be provided according to security requirements. This requires systems storing spatial data to not only prohibit different illegal attacks, but also to maintain information security when attacked and intruded and to provide data confidentiality based on the security requirements of each component when users access information. This paper provides principles of authorization design for spatial data based on RBAC (Role-Based Access Control) for users and security attributes defined for spatial objects. We propose to achieve confidentiality of spatial data repositories with respect to context analysis performed by inspecting clusters of spatial data for a given purpose (e.g. economic analysis, environment analysis of a territory) while tuning to their security constraints. Contexts group data to support detailed analysis and to improve users capabilities to take decisions. In order to let users access authorized spatial information, we introduce a selection methodology to filter the required context based on access permissions of users per role and per object." @default.
