Enhancing Healthcare Service By Using OPE with Cloud Databases

Abstract — Most of the healthcare organizations were lagging in adoption of new technology. But, in recent few years, researchers are able to enhance healthcare services by using technologies such as mobile devices, wireless sensor networks and cloud computing. Although there is improvement in healthcare services, use of untrustworthy cloud service provider possesses a serious risk on privacy of client’s medical data and intellectual property of the mobile health service provider. In addition to that, existing research efforts do not support SQL (Structured Query Language) range queries over encrypted health records stored in cloud database. To address above problems, this paper proposes a novel design of secure mobile healthcare monitoring. The proposed system makes use of Order Preserving Encryption (OPE) technique to provide confidentiality of health records as well as to support range queries over encrypted database.
