Toward User-Centric Privacy-Aware User Profile Ontology for Future Services

Personalization is one of the key features of the future Internet. However, the success of personalized services mostly relies on user profiles. Therefore, a generic, shareable, and reusable user profile is crucial for service providers for the uptake of personalized services. This paper proposes a user-centric personalization approach. The core of this approach is a user-centric user profile where user is in the center and experience perceived control over his information. We use Ontology Web Language (OWL-DL) to formally represent user relevant information in ontology. We present profile and privacy enhancement mechanism to increase profile applicability and user privacy respectively. The paper also offers a policy based approach to ensure authorized access of user profiles among third parties. Furthermore, we formally represent authorization policies by exploiting Semantic Web Rule Language (SWRL) and evaluate policies by employing Semantic Query Enhanced Web Rule Language (SQWRL).
