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.

Using Identity-Based Cryptography as a Foundation for an Effective and Secure Cloud Model for E-Health

Computational Intelligence and Neuroscience, Journal Year: 2022, Volume and Issue: 2022, P. 1 - 8

Published: April 25, 2022

Nowadays, one of the most popular applications is cloud computing for storing data and information through World Wide Web. Since has become available, users are rapidly increasing. Cloud enables to obtain a better more effective application at lower cost in satisfactory way. Health services must therefore be kept as safe secure possible because release this could have serious consequences patients. A framework security privacy employed store manage extremely sensitive data. Patients’ confidential health records been encrypted saved using cypher text so far. To ensure environment big issue. The medical system designed standard, access records, use by practitioners required. In paper, we propose novel algorithm along with implementation details an E-health model identity-based cryptography. comparison proposed existing techniques carried out terms time taken encryption decryption, energy, power. Decryption decreased up 50% method As it will take less power consumed doing cryptography operations.
