Enhancing security in IoT healthcare services using fog computing

Abstract

Internet of Things (IoT) is the networking of physical devices that are both connected and smart. With the advancement in IoT devices particularly in healthcare sector, huge amount of data is collected from different sensors and all this data are transferred and stored in cloud. It becomes difficult to handle such huge amount of data in cloud specially the healthcare data where it requires real time data computation and storage. Security of the data is also major challenge in cloud. Fog computing is the answer to overcome the challenges. Fog nodes works at the edge side and enhances data security, accuracy, consistency and reduces the latency rate which is an important factor for application like medical data. Even though there are much advantages fog computing also faces some kind of security issues and challenges. Fog-enabled smart health raises a series of challenges in terms of efficient cooperation among healthcare devices, fog nodes, and the cloud server, as well as security and privacy issues.
