BIoMT: A State-of-the-Art Consortium Serverless Network Architecture for Healthcare System Using Blockchain Smart Contracts

IEEE Access, Journal Year: 2022, Volume and Issue: 10, P. 78887 - 78898

Published: Jan. 1, 2022

Owing to the sensitive nature of healthcare data, aforementioned approach transferring patient data central servers creates serious security and privacy issues. In addition, blockchain distributed ledger technology has introduced immutable storage decentralized management capability, which handles a large number nodes E-Healthcare transactions via serverless network, but in limited manner because blockchain-enabled resources. this scenario, medical industries are concerned about constituting an innovation health information preservation exchanging service delivery protocols without connectivity untrusted third-party infrastructure. study, we proposed hyperledger fabric-enabled consortium architecture called BIoMT, provides security, integrity, transparency, provenance health-related exchanges clinical peer-to-peer (P2P) secure network environment. A consensus is designed created reduce rate resource constraints on Internet Medical Things (IoMT). The individual before sharing protected using NuCypher Re-Encryption mechanism, increases integrity transparency. Smart contracts deployed automate device registration, exchange transactions, (filecoin) after cross verification validation. experimental results show that BIoMT reduces computational cost by 26.13%, robust node generation 60.37%. Thus, only 31.79% 74.21% IoMT-related P2P usage maintained saved, respectively.
