Cloud E-health Systems: A Survay on Security Challenges and Solutions

A Survey on Secure Cloud-Based E-Health Systems

“…The review consists of the papers based on maintaining the security criteria of the cloud-based e-health system, what are the security issues and the solutions resolving the issues. The literature used in this review paper is filtered using the following criteria mentioned in table (1) and the number of papers included and excluded from different search engines for the review with respect to the criteria mentioned is given in table (2). (1).…”

“…It is far more secure and has better customization than the pre-mentioned cloud system. Examples of this cloud system are Dell, IBM, Cisco, HP [1,2]. Figures of basic public e-health cloud systems and private e-health cloud systems are shown in figure (a) and (b) respectively.…”

“…Moreover, cloud computing requires resources like software and hardware from the user's side [1]. Cloud has the ability to accommodate multiple applications for a mass of users who can use those applications for accessing and sharing the data with great flexibility, accessibility, and reliability [5].…”

“…The e-health (electronic health) system as the name suggests is a kind of health system which uses computer or electronic systems and cloud technology as its main source of operations for storing and sharing patient's medical data between healthcare service providers and patients [1]. It is different from the pen-paper based traditional health system.…”

“…To achieve security, the three methods used are: one is crypto methods, it consists of symmetric encryption, asymmetric encryption, attribute-based encryption, and hybrid methods. Another one is non-crypto methods which include access control, role-based policy implementation methods for defining the roles of every single user with their right of access [1]. The third one is the biometric-based methods which use biometric traits of a person for user authentication and authorization purpose.…”
