Integration of Personal Health Record Using Database System and Blockchain Access Control Based on Smartphone

Healthcare is one of the rapidly growing domains with the development of technology and information in order of providing improved health and medical services to the community. The development of information technology predicts blockchain as a future solution for medical information and storage technology. With the large number of medical information sources made of medical records, blockchain provide alternative options for the transition of medical record information from clinical-centered to patient-centered. The need for data protection and data sharing in this transition makes blockchain with chain information systems able to provide additional security in access control of medical records. In this research, we explores and analyzes the need for integrating and managing Personal Health Records from patient medical records, by implementing the technology of blockchain. Accompanied by a NoSQL database system, the design of a system to perform patient-centered-based medical record management can be initiated using smartphones as the media. The results of the analysis were developed in the form of the myHealth Medical Record Management application covering 4 categories of the user interface. The application was developed in Flutter Framework alongside Google Firebase as an authenticator and database provider, combined with a connection to an Ethereum-based blockchain client running on a virtual machine. The application can be installed on the smartphone with the Android Operating System. Blockchain provides an average response time of 850.0333 milliseconds covering 9 smart contract functions and also database system can provide download and upload processes in 19 different types of medical record attachment with an average speed of 0.517 kilobytes per second and 0.9344 kilobytes per second respectively. It is proposed that with this application, patient-centered medical records can develop and educate users for an independent medical record management system
