Pervasive environments pose extended security and privacy threads if compared with traditional systems. Many privacy enhancing and trust management techniques have been studied in recent years. In the paper we present the DAIDALOS IST FP6 Integrated Project[1] approach to enabling privacy in pervasive information systems. In DAIDALOS privacy enabling is approached in a systemic and manageable fashion. To enable privacy we use a fusion of techniques that bring together various technologies and research disciplines from the field of privacy engineering: automatic agent negotiation, identity management, and trust management. As a solution to the complex problems imposed by pervasive environments we propose privacy enabling architecture of the DAIDALOS platform. Privacy enabling solutions are in service to user communication and exploit the system feedback loop where experience gained in one communication cycle is feed back via updating of the reputation models. Entities involved in communication first have to negotiate privacy agreements based upon trustworthiness, afterwards appropriate virtual identities are created or selected and in the last phase privacy agreements violations are considered and trustworthiness of the communicating entities are lowered.
