A Hyperledger Fabric-based Blockchain Architecture to Secure IoT-based Health Monitoring Systems

Abstract

Although blockchain is a promising technology that can bring significant benefits into current centralized IoT-based health monitoring systems in order to address security challenges, the resource-constrained IoT devices of these systems cannot afford complex and heavyweight operations due to their limited processing power, storage capacity, and battery life. Therefore, in this paper, we propose a Hyperledger Fabric-based blockchain architecture to: i) enhance security in IoT-based health monitoring systems, ii) achieve better storage handling due to the limited storage capacity of sensors and gateways, iii) facilitate decentralized accountability, and iv) eliminate single point of failure.
