tailieunhanh - Securing patient privacy in e health cloud using homomorphic encryption and access control

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. | International Journal of Computer Networks and Communications Security C , , JANUARY 2014, 15–21 Available online at: ISSN 2308-9830 N C S Securing Patient Privacy in E-Health Cloud Using Homomorphic Encryption and Access Control Aderonke Justina.

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. Keywords: Access Control, Cloud Computing, e-Health, Homomorphic Encryption, Security. 1 INTRODUCTION Electronic Health Record (EHR) is a digital record shared across different healthcare settings, by network-connected enterprise-wide information systems called EHR systems [8]. Electronic form of personal health records opens new kind of threats to information leakage
