Context-Aware Learning Privacy Disclosure Policy from Interaction History

Context-aware applications use personal information to provide appropriate services for people. This personal information is often involved in personal privacy. In order to balance the personal privacy concerns against enjoying context-aware services, we propose a conceptual framework and privacy role to control access personal information. Privacy disclosure policy can be learned from people´s interaction history about personal information disclosure using rough set theory. According to deducing from the privacy disclosure policy and context information, a context-aware application is assigned to an adequate privacy role. A case analysis and the initial performance evaluation show that the proposed method is effective.
