Blockchain Based Mobile-Patient Medical Records Management System

The study outlines a blockchain-based mobile app-based patient records management system that aims to store and exchange all data in a more safe and open manner. The system was developed using Android Studio based on flutter SDK. Since flutter is a free and open-source software development kit that facilitates the creation of mobile apps that run on several platform, technological study based on flutter programming language has been chosen to be utilized for the implementation. The extendable, scalable, and adaptive nature of the language is more effective. Safekeeping and updating of medical records on paper is a major challenge. Additionally, these can be easily lost and swapped. Other existing electronic record systems lack robust security and in cases of emergencies can pose a delay. Thereby, this project proposes leveraging features of the blockchain technology by developing an easy-to-use mobile app, so that healthcare establishments can overcome the limitations identified in current systems while revolutionizing the healthcare system. To ascertain the issue’s scalability, rigorous testing was carried out. The system architecture, user requirements, interface designs, necessary sequential patterns and the development process have been documented in this paper.
