Secured Health Data Sharing System Using Ipfs and Blockchain with Beacon Proxy

Abstract

Transfer of data over the blockchain is significantly improved over the years. This proposed system gives a unique method of transferring patient health data to another hospital or to a peer, using a blockchain-based web application that places patient ownership and data security at the forefront. Patient data is stored in a decentralized and distributed manner using the Interplanetary File System(IPFS), eliminating the need for a central authority. Smart contracts written in Solidity facilitate transactions by checking for sufficient funds and managing the transaction process. Abeacon proxy is used to automatically update patientownership in the smart contract, reducing errors and inaccuracies resulting from manual intervention. The blockchain network offers a secure and decentralized solution for transferring patient health data, ensuring privacy and accessibility only to authorized individuals through advanced cryptographic techniques, distributed data storage, and smart contracts. © 2023 Elsevier B.V..
