Healthcare is an increasingly collaborative enterprise involving many individuals and organizations that coordinate their efforts toward promoting quality and efficient delivery of healthcare through the use of pervasive healthcare systems. In such systems, interoperability is highly demanded in all the levels including the service and data levels. This paper presents a distributed context-aware access control mechanism for pervasive process-based healthcare systems built on a Grid infrastructure. The system uses the Business Process Execution Language (BPEL) to automate healthcare processes on a Grid infrastructure. Client applications are portal-based, operate on mobile devices and can use radio frequency identification (RFID) technology for wireless capture of identification data. The proposed access control mechanism acts as a mediator between the clients and the underlying system and adheres to the least privilege principle by allowing authorized access to integrated data in a ubiquitous and pervasive manner. The mechanism is built on a software platform that exploits agent and workflow technology, thus providing robustness, high flexibility and fault tolerance in authorization procedures.
