Secure Electronic Medical Records Storage and Sharing Using Blockchain Technology

Abstract

Electronic medical records (EMRs) are electronically-stored highly sensitive and private information related to the diagnosis and treatment of patient, and needs to be frequently shared among peers. Sharing of medical records between participants is very challenging because the data might be revealed or tampered during the operational process. To address these challenges, a blockchain-based electronic medical records system is the key solution. In this research, we have discussed how blockchain technology can help in better healthcare data management. We have proposed a blockchain-based records management system for efficient management and sharing of electronic medical records (EMRs). We have implemented a prototype of Electronic Medical Records Management System using permissioned blockchain platform “Hyperledger”. This system ensures privacy, security and easy accessibility and availability of medical records.
