Abstract

In the current era of technological smart world blockchain technology has bought revolution in Electronic Health Record’s (EHR’s) data exchange, which is important within medical research and healthcare. The healthcare industries are overlooked with problems in secure data exchange and privacy protection. The scoping review aims to identify the Blockchain technology used in health- care organization could help in addressing privacy and accessibility issues. The distributed ledger technology is integrated with IPFS-Interplanetary file system helps in accomplishing firm controllable blockchain-based Electronic Health Records (EHR) data exchange scheme. To share and save large health record files between healthcare institutions the Electronic Health Records (EHR) with IPFS-Interplanetary file system is a promising solution. The decen- tralized block storage and integrated Electronic Health Records (EHR) with Interplanetary File System (IPFS) achieve failure of accessing health records. The study designate that personal health documents and Electronic Health Reports are the bulk chosen areas, using distributed ledger technology. Inter- operability, data integrity and authentication are the major concern need to be refined by blockchain technology. The most used platforms in EHR blockchain are hyperledger fabric and ethereum. The study also inspects the reliable data share of EHRs among mobile users through mobile cloud to ensure high security levels. The combination of distributed Interplanetary file system and mobile cloud blockchain platform is reliable data exchange mechanism by applying smart agreements for efficient Electronic Health Records data sharing among distinct medical providers and patients to access control mechanism.
