CoreMedi: Secure Medical Records Sharing Using Blockchain Technology

Abstract

Individual medical records have a high priority of integrity and security, yet they are vulnerable to data breaches and manipulation. It’s vital to communicate these data in a secure and safe manner. To overcome this problem, the proposed solution named, CoreMedi, uses blockchain technology to store and share medical data. Data stored on blockchain is immutable, verifiable and transparent (based on accessibility). As data cannot be altered on blockchain, the rate of fraud may be drastically decreased. With the help of smart contracts which are small pieces of code that run on blockchain, a Decentralized Application (DApps) is designed and implemented that enables patients/individuals to store and share medical records securely. Users may share their medical history, medications, and personal data with a specific medical personnel on the same blockchain network using CoreMedi, a Decentralized Web application. The application is implemented with React as frontend and the backend infrastructure uses Ethereum solidity smart contracts. The process of running a blockchain application is not simple because the users must be willing to spend crytpocurrencies as gas fees, as this is the way to maintain the network with no single organization having control.
