title = "Blockchain-Enabled Electronic Medical Record with Hyperledger Composer",
abstract = "Medical records are files that contain records and documents about patients' identities, examinations, treatments and actions, and other services while the patients are receiving health services. Medical records are personal data that can only be accessed by authorized personnel. Some problems occur, such as the difficulty in managing files for grouping patients' medical record data based on specific categories such as the documentation year or patients' biodata. A large storage area is needed to hold medical record data and the absence of backup data in data storage. Blockchain-based solutions help overcome this problem. Hyperledger Composer is an open and extensive development framework for blockchain systems. Hyperledger Composer allows us to quickly model business networks and integrate them into an application or system that we have created easy and save time. Hyperledger consists of 3 main files, model file, script file, and access control file, which have coding flexibility and are easier to understand. Hyperledger Composer uses the JavaScript language for coding and has a client library for node.js. In this study, we propose a medical record sharing model that combines blockchain with the Hyperledger Composer and conducts a performance evaluation of the implementation. The result shows the increase of transactions during testing in which the system could store data into blocks to record medical transactions.",
