A Blockchain-Based Distributed Authentication System for Healthcare

The use of digital health records, stricter health laws, and the growing need for health records exchange point towards the need for an efficient security and privacy preserving mechanism. For health insurance management systems, multiple entities exchange health information, which is used for decision making. Since multiple authoritative entities are involved, a secure and efficient information sharing protocol is required as extremely sensitive health information is exchanged among the entities. Hence, this paper aims to put forward a novel a decentralized authentication system based on blockchain known as insurance claim blockchain (ICBChain) system. The proposed system ensures privacy of patients and provides secure information exchange and authentication of entities. An implementation of the proposed system is provided using Ethereum blockchain. The security and performance analysis of the system shows its potential to satisfy healthcare security requirements and its efficiency, respectively.
