Collaborative business paradigm federates multiple organizations dynamically to exchange value and support common goal. Security in such context has new traits: as partners share asset (service and information) to provide final artifact for consumer, their concerns are not only about the secure communication and secured platform, but also about asset to be consumed in an expected way. This paper presents a collaborative-context oriented policy model to enable the expression of provider's end-to-end security requirements. It bases on fine-grained access model as usage-control, and comes up with negotiation and aggregation algorithms that are aware of collaborative context.
