Enforcing Privacy in a Semantic Web

Lecturer: Dr. Dieter Hutter (DFKI-Lab Bremen)

The vision of a landscape of heterogeneous web services deployed as encapsulated business software assets in the Internet is currently becoming a reality as part of the Semantic Web. When pro-active agents handle the context-aware discovery, acquisition, composition, and management of application services and data, ensuring the security of customers’ data becomes a principle task. To dynamically compose its offered service, an agent has to process and spread confidential data to other web services demanding the required degree of security. In this talk we propose methodologies and techniques based on language-based information flow control to secure both user provided and dynamically computed data and their proliferation within a set of communicating web services.
