The future of healthcare systems is being shaped by incorporating emerged
technological innovations to drive new models for patient care. By acquiring,
integrating, analyzing, and exchanging medical data at different system levels,
new practices can be introduced, offering a radical improvement to healthcare
services. This paper presents a novel smart and secure Healthcare system
(ssHealth), which, leveraging advances in edge computing and blockchain
technologies, permits epidemics discovering, remote monitoring, and fast
emergency response. The proposed system also allows for secure medical data
exchange among local healthcare entities, thus realizing the integration of
multiple national and international entities and enabling the correlation of
critical medical events for, e.g., emerging epidemics management and control.
In particular, we develop a blockchain-based architecture and enable a flexible
configuration thereof, which optimize medical data sharing between different
health entities and fulfil the diverse levels of Quality of Service (QoS) that
ssHealth may require. Finally, we highlight the benefits of the proposed
ssHealth system and possible directions for future research.
