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. A beacon proxy is used to automatically update patient ownership 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.
