Secure System Medical Record with Blockchain System: Recchain Framework

Medical records are very important and provide benefits that are felt by patients, doctors and other health workers in terms of clinical decision making. Seeing the importance of the presence of medical records, Indonesia has also implemented innovation in the use of technology in the application of digital medical records. However, until now there are still problems that occur in the application of the existing medical record technology which is centralized so it is still difficult to get the trust of patients. Therefore, in this case the research will have the object of research in storing medical record databases without the involvement of third parties. (Decentralized) So as a solution, this research will present a schematic system of architecture RecChain(Record Blockchain) with the advantages of being transparent and decentralized for the purpose of increasing patient trust in medical records with a decentralized and transparent database. In RecChain's research, it is not limited to decentralization, external provider medical record data, and smart contract networks. The results of the research obtained, the RecChain system can minimize data misuse, and the proposed scheme design will not depend on the Blockchain platform which makes the scheme have the potential for wider application in other health electronics to increase the tightness of system data protection.
