However, without any security measures, hospitals can be easy targets for data breaches, ransomware attack, denial-of-service attack, and phishing, just to name a few. To examine the privacy and security of e-health systems, major components of the present-day wireless healthcare system have been identified. Recent privacy and security studies that focus on components of the e-health systems have been reviewed. On the basis of the reviews, open challenges, research trends, solutions, requirements, and security issues of a wireless healthcare system have been obtained.
