Summary Cooperation requires sharing data, but enforcing access restrictions across enterprises is a challenge. Different sites have different policies and use a variety of access control methods that are tailored to the individual enterprises' needs. Mapping one set of rules into another may require complex computations, possibly with a separate method for each pair of sites. This paper proposes an information flow control model for enforcing access restrictions across a virtual enterprise. Labels are assigned to data structures to ensure uniform treatment across the enterprise, and dynamic label checking provides flexibility during operation. A set of rules are presented to facilitate data manipulation so that they do not lead to information leak. The proposed solution particularly suits web-based environments and web services operations.
