Context Sensitive Access Control

This presentation is about the practical feasibility of using context information for controlling access to services. Based solely on situational context, users can be transparently provided anonymous access to services and service providers can still impose various security levels. Thereto, we propose context-sensitive verification methods that allow to check the user's claimed authenticity in various ways and to various degrees. More precisely, conventional information management approaches are used to compare historic contextual (service usage) data of an individual user or group. The result is a relatively strong, less intrusive and more flexible access control.
