A privacy-respecting context-aware architecture

This paper targets personal privacy protection concerns in context-aware ubiquitous computing environments. It proposes a generic context-aware architecture that is specially designed with privacy protection in mind. The proposed context-aware architecture provides functional support for context collecting, storage, processing and dissemination. It also provisions access control mechanisms to protect context information against unauthorized access, and develops a privacy agent technology to enable individuals to manage their privacy requirements towards dynamic context-aware environments with relative ease.
