Blockchain-Based Decentralized Secure Healthcare System Using Ethereum Smart Contracts

Abstract

Blockchain for health care has the potential to standardize secure data exchange in a less burdensome burdensome way. Traditional data-sharing platforms rely on a third party. Owning to the consideration of a third party, such systems compromised transparency, trust, and integrity. To solve the aforementioned issues, we have proposed a smart contract-based secure data-sharing scheme in healthcare by leveraging the advantages of the interplanetary file system (IPFS). Our scheme achieves data confidentiality, integrity, and access control rules by implementing the access control policy written in a smart contract by active entities. This thesis is to attain higher levels of medical records security using Ethereum Blockchain methods. Finally, it also helps organ donation, to incentivize medical stakeholders such as researchers, health authorities, etc. to participate in the network as blockchain miners. This provides them with access to aggregate, anonymous data mining awards in return for sustaining, and securing the network. Keywords: Blockchain, Ethereum, Medical Records, Storing System, IPFS
