A Smart contract-based secure data sharing scheme in Healthcare 5.0

In-Patient Monitoring, data sharing is fundamental step to get the comprehension from earlier research-oriented work. Traditional data-sharing policies rely on third-party holders that can compromise the system transparency, trust, and integrity. To solve the aforementioned issues, we have proposed a smart contract-based secure data sharing scheme in healthcare 5.0 by leveraging the advantages of the interplanetary file system (IPFS). The proposed scheme achieves data confidentiality, integrity, and access control rules by implementing active entities’ access control policy written in a smart contract. Entities are first authenticated using digital signatures. Afterwards, the completion of treatment initiated the transaction and transferred the amount to the requested entities. This scheme integrates Ethereum blockchain (BCN), decentralized storage, and incentive schemes. In this scheme, smart contracts are written in solidity language and deployed on the Ethereum-based test network. The proposed scheme achieves data integrity, confidentiality, authentication, and non-repudiation. The result section calculates the communication and computation cost of 1408 bits and 0.112 ms, respectively.
