  We propose an agile softwarized infrastructure for flexible, cost effective,
secure and privacy preserving deployment of Internet of Things (IoT) for smart
healthcare applications and services. It integrates state-of-the-art networking
and virtualization techniques across IoT, fog and cloud domains, employing
Blockchain, Tor and message brokers to provide security and privacy for
patients and healthcare providers. We propose a novel platform using
Machine-to-Machine (M2M) messaging and rule-based beacons for seamless data
management and discuss the role of data and decision fusion in the cloud and
the fog, respectively, for smart healthcare applications and services.
