Abstract
Ubiquitous healthcare information system is increasingly seen as a viable option for reducing the inherent time lag and inaccuracies in the traditional model of healthcare and promoting the delivery and practice of evidence-based healthcare-as and when needed-without any location and time constraints. Although promising, the realization of ubiquitous healthcare information system brings several threats and risks rooted in real-time collection, analysis, storage, transmission, and access of critical medical data. In this research, we address information security concerns pertaining to the paradigm of ubiquitous healthcare information system. To accomplish this we use National Institute for Standards and Technology's (NIST's) system development lifecycle model (SDLC) as the underlying framework to explore the current state of ubiquitous healthcare from the perspective of security. We then leverage the model to propose future research directions in this area. By implementing the NIST's SDLC model in such a manner, we offer a different dynamic of healthcare security that has not been addressed in literature before.
