Securing Patient Privacy in E-Health Cloud Using Homomorphic Encryption and Access Control
International Journal of Computer Networks and Communications Security · 2014
Cloud computing paradigm is one of the popular Health Information Technology infrastructures for facilitating Electronic Health Record (EHR) sharing and EHR integration.Healthcare clouds offer new possibilities, such as easy and ubiquitous access to medical data, and opportunities for new business models.However, they also bear new risks and raise challenges with respect to security and privacy aspects.Ensuring the security and privacy is a major factor in the cloud computing environment.A Secured Cloud based aided medical system is a program designed to aid standard and effective use and access of patient records anytime it is required by medical practitioners.In this paper, a Secured e-Health System called SECHA is proposed.SECHA comprises of five basic component namely; patient, PHR/object, Access Control Module, User/Subject and Cloud.This proposed system ensure the security of electronic health records stored in the cloud using Homomorphic Encryption to secure patients medical records and Bilayer Access Control to gives access right to the records.
