Abstract

The Internet is moving towards dynamic and ad-hoc service composition. The resulting so-called Web 2.0 sites maintain a unified user-experience while interacting and exchanging personal data with multiple other sites. Since the interaction is dynamic and ad-hoc, existing privacy policy mechanisms are not designed for this scenario. In this article we describe a new lightweight approach towards privacy management. The core idea is to provide a "privacy panel" - a unified and simple entry point at each site that enables consumers to review stored data and manage their privacy. Key aspects were ease-of-use and handling of recursive disclosures of personal data.
