Zusammenfassung
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 paper we propose a methodology
based on type-based information flow to control the privacy of
data and their proliferation within a set of communicating web services.
