A Survey on Secure Framework for Privacy-Preserving Over EHR in Cloud Environment

The "Health Service Provider (HSP)" sector is set to be revolutionized by the advent of an emerging technology referred to as "Cloud Computing (CC)".CC's numerous upsides include adaptability, minimal costs, collaborative resources, and rapid implementation.With both individuals and HSPs, the centralized management of data with the cloud creates several confidentiality and safety problems.In addition to shifting control over data to the "Cloud Service Provider (CSP)", data centralization enhances the chances for hackers to gain possession of documents and monitor data when it passes.As a result, both the individual and HSP are at risk of private information being compromised.As a consequence, the widespread acceptance of CC is slowed by issues about integrity, safety, performance, and flexibility.A thorough and methodical analysis of the security and "Privacy-Preserving (PP)" problems associated with HSP systems is presented in this article, along with several PP strategies to guarantee the privacy and security of "Electronic Health Records (EHRs)" within the cloud.This study discusses the difficulties and potential avenues for further research regarding EHR security.Several articles were researched, studied, and analyzed to identify the following areas: cloud-based architecture for EHR, cloud privacy and security necessities for EHR, and different "Cryptography", "Non-Cryptography", and "Biometric" techniques for EHR.It has been observed that the most recent technologies only partially address these issues.In addition, it looks over a few important concerns as well as the many chances for cutting-edge research on EHR security and privacy.A comprehensive approach that strikes a balance between all the conflicting needs is thus critically required.
