Privacy preserving mechanisms for enforcing security and privacy requirements in E-health solutions

In the last few decades, there have been significant efforts in integrating information and communication technologies (ICT) into healthcare practices. This new paradigm commonly identified as electronic healthcare (e-health) allows provisioning of healthcare services at an affordable price to its consumers. However, there have been questions raised about the security of the sensitive information such as health records as well as the privacy of involving parties raising doubts on the minds of the general public. Thus, it is important to understand the potential security challenges in e-health systems and successfully resolve them by taking adequate measures to ensure fair utilization of such systems. In this paper, we have carried out a systematic state-of-the-art review over privacy preserving mechanisms that have been utilized on e-health solutions to achieve the security and privacy requirements while investigating to what extent such mechanisms are compatible with the identified requirements. Finally, we have pointed out some future research directions which could potentially contribute to develop secure and efficient e-health solutions.
