Abstract
Cooperative distributed systems (CDS) approach is a promising design paradigm that is suitable for many applications such as healthcare, virtual enterprises, ebusiness and tele-learning in which entities have some degree of authority to sharing their capabilities. Brokering is a capability-based coordination approach for CDS. A major challenge of brokering in open environments is to support privacy. Within the context of brokering, we model privacy in terms of the entities’ ability to hide or reveal information related to its identities, requests, and/or capabilities. In this work we present in-depth analysis of the capabilitybased coordination and propose a privacy-based brokering framework and interaction protocols that support different privacy degrees. Unlike traditional approaches, the brokering is viewed as a set of services in which the brokering role is further classified into several sub-roles each with a specific architecture and interaction protocol that is appropriate to support a required privacy degree. A formal specification of the privacy-based brokering protocols is represented using an Input/Output Automata model. To put the formulation in practice, a prototype of the proposed architecture has been implemented to support informationgathering capabilities in healthcare environments. '
