A Study on Privacy Preservation of Medical Certificates Using Blockchain Technology

Abstract

: Currently, blockchain technology has evolved into a reliable and secure platform to provide security for the data. This technology's main adoption areas are agriculture, supply chain, food sector, energy industries, Health care, Real estate, Voting system, and education sector. This paper reviewed existing related works and applications using blockchain technology. Forgery or fraud on medical documents is a significant challenge in the health care sector. Hence this paper proposed a Blockchain-based framework using Ehterum that is a public blockchain. Users required medical documents generated and issued by officials authentically in the way of a unique blockchain-based ID. Users can submit this Blockchain-based ID anywhere instead of a physical paper. Attacks or forgery on the medical document can reduce using advanced featured technology, Blockchain. Blockchain technology has the features such as immutable, distributive, secure, reliable, and transparent. Remix Etherum IDE, solidity programming, and Metamask Wallet were used to implement the proposed application. The main strength of this work is designing and deploying results and comparisons with the existing applications.
