Cloud E-health Systems: A Survay on Security Challenges and Solutions
Mohammed Ali Kamoona, Ahmad Mousa Altamimi · 2018
Cloud progression have led it to be adapted in many aspects and application that serve human demands. One of the recent trends in cloud computing is the e-health services, as many healthcare institutes have begun to interchange toward the digitalized version of health records. E-health provide easy sharing of personal health care records between multiple organizations and offered real-time monitoring for the patient's state via storing this data over the cloud servers. However, having the data in such a distributed setting rises the need for having a secured data sharing with fine- grained access control, as the records are stored in a third-party service provider that is considered a semi trusted. Also, many different aspects of security should be taken into count with e-health, for instance the data is critical and should be only available to its owners. Numerous works have been done to secure the medical data in cloud environment. This work focuses on the security challenges and solutions for on Cloud-based E-health systems. Specifically, a state of the art is presented to preserve and protect E-health data, which consists of two tiers: cryptographic and non-cryptographic approach. Also, some of main issues and open problems that can be used in future studies are pointed out in this work.
