Abstract

We consider a type of applications where collaboration and trust are tightly coupled with the need to protect sensitive information. Existing trust management technologies have been limited to offering generic mechanisms for enforcing access control policies based on exchanged credentials, and rarely deal with the situated meaning of trust in a specific collaborative context. Towards trust management for highly dynamic and collaborative activities, this paper describes a theory of trust intention and semantics that makes explicit connections between collaborative activities and trust. The model supports inferring trust state based on knowledge about state of collaborative activity. It is the first step towards a unified approach for computer-mediated trust communication in the context of collaborative work.
