Abstract : The growth of cloud computing has emerged as a critical enabling technology for today's healthcare systems, providing on-demand access to large amounts of medical data, including electronic health records (EHRs), diagnostic images, and clinical documentation. However, the benefits of cloud-based medical information will be contradicted by challenges with securing and maintaining the privacy of electronic medical records. The medical data hosted in cloud computing environments (such as hospitals) is at risk of being stored and opened inappropriately or accessed inappropriately. This research focused on the current practices used to secure sensitive data, including access control and virus protection. A number of different encryption mechanisms are available to ensure that sensitive medical records remain confidential at the time of storage and/or in transit. A number of different access control models are available to provide structured methods to manage user access, user authentication, etc. The proposed research presents a new layered security model integrating encryption with role-based authorization and identity authentication. A functioning example of this research demonstrates how authentication, authorization, and activity logging can be leveraged to prevent unauthorized access to healthcare records. The results of the study show that the use of encryption technologies with a structured access policy for accessing sensitive healthcare records will greatly improve the security and access to sensitive medical information for authorized medical personnel utilizing cloud-based healthcare systems.
