A User Interface to Define and Adjust Policies for Dynamic User Models

Abstract

Abstract:A fine-grained user-aware access control to user profile data is the key requirement for sharing user profiles among applications, and hence improving the effort of these systems massively. Policy languages like Protune can handle access restrictions very well but are too complicated to be used by non-experts. In this paper, we identify policy templates and embed them into a user interface that enables users to specify powerful access policies and makes them aware of the current and future consequences of their policies.
