22nd Conference of the International Society for Telemedicine and eHealth and Moroccan Society for Telemedicine and eHealth 2017 - Casablanca 2017

Data used in health care is being analysed and stored in data centres.This data is part of what today we refer as Big Data.Additionally, in the last few years it has been an explosion of IoT devices, such as sensors and actuators.A lot of them are used to obtain health related parameters.In this paper the concept of Health Small Data (HSD) is introduced.HSD refers to the data received from these IoT devices and additional personal health information for each person.We claim that thanks to the convergence of Internet, IoT and HSD a new way to provide Integrated Health Care (IHC) in a very personal, secured and ultra-fast can be deployed through the implementation of Personal Health Assistants (PHAs) in nodes closer to the end user, offering a much reduced latency and releasing the medical system of simple.The technology platform for PHA is based on Fog Computing, the Health Fog (HFog) through the deployment of HFog nodes that will handle HSD regarding the patients under its area of actuation.To ensure privacy and ownership of the information, this data will be maintained in the lower aggregation nodes of the Fog hierarchy.If a patient move to a new location served by a different Fog node then the HSD will be transferred to the new node in a secured (encrypted) way.
