Privacy-Preserving of Patient’s Electronic Health Records Using Public Key Encryption

Abstract

Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. The term is generally used to describe data centers available to many users over the Internet. Cloud computing is a recent paradigm in digital technology and is being extensively used in the healthcare industry. It not only provides convenient storage of medical information but also facilitates the easy exchange or transmission of medical data among various stakeholders. A systematic and comprehensive review of security and privacy-preserving challenges in e-health solutions indicates various privacy preserving approaches to ensure privacy and security of electronic health records (EHRs) in the cloud. This paper highlights the research challenges and directions concerning cyber security to build a comprehensive security model for EHR. We surveyed, investigated, and reviewed various aspects of several articles and identified the following tasks:  EHR security and privacy; security and privacy requirements of e-health data in the cloud; EHR cloud architecture, and diverse EHR cryptographic and non-cryptographic approaches. We also discuss some crucial issues and the ample opportunities for advanced research related to security and privacy of EHRs. Since big data provide a great mine of information and knowledge in e-Health applications, serious privacy and security challenges that require immediate attention exist.
