In this report, we describe the design and functioning of a logic-based framework for privacy evaluation and user feedback. This framework is meant to be running on the user’s side and to track user’s actions, i.e. disclosures that she makes, in order to evaluate the profiles different providers hold about her. The evaluation is based on the utilised credential technologies, providers’ authentication, data storage and data sharing policies and on actual interactions between the user and providers when services are consumed. Besides providing feedback on the achieved privacy level, the framework can also be applied for inspecting the consequences of potential subsequent disclosures. This allows the user to make an informed decision on which disclosures to make or to choose between alternative authentication policies. ispartof: CW Reports nrpages: 27 status: published |
