Aguhyper: a hyperledger-based electronic health record management framework
Özet
The increasing importance of healthcare records, particularly given the emergence of
new diseases, emphasizes the need for secure electronic storage and dissemination.
With these records dispersed across diverse healthcare entities, their physical
maintenance proves to be excessively time-consuming. The prevalent management
of electronic healthcare records (EHRs) presents inherent security vulnerabilities,
including susceptibility to attacks and potential breaches orchestrated by malicious
actors. To tackle these challenges, this article introduces AguHyper, a secure storage
and sharing solution for EHRs built on a permissioned blockchain framework.
AguHyper utilizes Hyperledger Fabric and the InterPlanetary Distributed File System
(IPFS). Hyperledger Fabric establishes the blockchain network, while IPFS manages
the off-chain storage of encrypted data, with hash values securely stored within the
blockchain. Focusing on security, privacy, scalability, and data integrity, AguHyper’s
decentralized architecture eliminates single points of failure and ensures
transparency for all network participants. The study develops a prototype to address
gaps identified in prior research, providing insights into blockchain technology
applications in healthcare. Detailed analyses of system architecture, AguHyper’s
implementation configurations, and performance assessments with diverse datasets
are provided. The experimental setup incorporates CouchDB and the Raft consensus
mechanism, enabling a thorough comparison of system performance against existing
studies in terms of throughput and latency. This contributes significantly to a
comprehensive evaluation of the proposed solution and offers a unique perspective
on existing literature in the field.
