Dependable Service-Oriented Design of Healthcare IoT

Healthcare Internet of Things (HIoT) is transforming healthcare industry by providing large scale connectivity for medical devices, patients, physicians, clinical staff, and nurses who may use them remotely to facilitate real-time monitoring based on the information gathered from the connected medical devices. This network provides both opportunity and challenges for collecting relevant healthcare information and sharing it for innovative research and efficient healthcare provision. Patient-centric information such as their health status and medical devices used by them must be protected to provide safety and offer privacy, while healthcare knowledge should be shared in confidence by experts for healthcare innovation and timely treatment of patients. In this paper a dependable service-oriented 3-tier architecture of HIoT is proposed. Context-aware role-based access control scheme is discussed to ensure services in HIoT are dependable, in the sense that every service provided to any patient in the network, anywhere and at anytime is safe, secure, reliable, and the privacy of patient receiving it is protected.
