A Survey and Classification of Security and Privacy Research in Smart Healthcare Systems

Advances in wireless technology have resulted in the development of smart healthcare systems (SHSs). In SHS, sensors, wearables, and devices monitor a patient's vital parameters. These parameters are transmitted to the designated emergency services or the trusted healthcare professionals for evaluation. The security and privacy of vitals during collection and transmission are the major concerns. Therefore, it is essential to discuss security techniques, concerns, and requirements in SHS. We review the methodologies, objectives, platforms, and techniques used in SHS. First, we present a novel classification scheme for SHS that ranks their methodologies within their applicable domains. Second, we create a classification scheme for the literature concerning SHS. Third, we examine the most important security attacks in SHS and the countermeasures proposed in this paper. Finally, we identify the open-research challenges in security and privacy of SHS and provide directions for future research.
