N2 - Some hospitals have different Electronic Medical Records (EMR) systems in affect health services for patients. Electronic Medical Record data among hospitals can eliminate the process of reduplicating Electronic Medical Record data. Data sharing is still centralized and fails to provide logs and events that are trusted, secure, immutable, auditable, and decentralized. In addition, Electronic Medical Record data sharing is important to reward a hospital as a Data Owner for contributing to sharing its Electronic Medical Record data. Our paper provided an Electronic Medical Record data sharing scheme among hospitals with a blockchain solution using an Ethereum smart contract. Access to encrypted data kept on a decentralized storage platform is made possible through a re-encryption method used in conjunction with oracles. We provided the reward mechanism for each Hospital that shared their Electronic Medical Record data through rating techniques with other hospitals as Data Requesters. As a result, we improvised a proposed data-sharing scheme that is focused on Electronic Medical Record data in hospitals to solve the problem of differences in Electronic Medical Record data of patients among hospitals. We evaluated the proposed system with cost analysis and security analysis.
