Abstract
The use of digital health records, stricter health laws and the growing need for health records exchange points 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, 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
Highlights
The fast evolution of Blockchain is paving the way for a system, where multiple parties who do not know each other or who do not trust each other can work together to achieve consensus
The inherent characteristics possessed by Blockchain makes it pertinent for accomplishing such a vision .This the reason why application of Blockchain technology is not limited to finance sectors anymore
Manage Claimant Smart Contract (MCSC): The functions included in RSC are as follows: Add_Claimant (EA.C, ID.C and RN.Health Insurance Providers (HIP)) This function can only be executed by a Health insurance Provider to add claimants to the Blockchain network
Summary
The fast evolution of Blockchain is paving the way for a system, where multiple parties who do not know each other or who do not trust each other can work together to achieve consensus. There has been significant number of research conducted Blockchain and Healthcare in a combined way and the studies can be used to remodel the traditional procedures like health record storage and exchange, end to end drug provenance and traceability, medical claim processing etc. Blockchain, due to its inherent features like immutability, decentralization, verifiable, etc., is an apt solution for providing a secure storage and access environment for exchange of healthcare information (Fernández et al 2018). This study proposes a novel protocol that addresses the requirements of Healthcare applications like authentication, privacy of patients and their health records, secure data sharing, interoperability and integrity.
