Abstract

Blockchain is a disruptive technology that offers resources to reduce costs and bureaucracy in relationships between organizations, considering public, auditable and decentralized data records. There is a growing interest in new applications of this technology, in particular, for the control and sharing of electronic medical records (EMR). In this work, we propose B-Drive, a blockchain-based network infrastructure model for sharing EMRs between patients and various healthcare organizations. Different from existing approaches, our proposal considers a model of a permissioned network, patient-defined shares and integration of systems and infrastructures that already exist in organizations to deploy the blockchain network. Our results based on realistic experiments show the feasibility and minimum requirements for deploying a blockchain consortium for sharing EMRs.
