Aguhyper: a hyperledger-based electronic health record management framework

Area of Science:

• Health Informatics
• Computer Science
• Cybersecurity

Background:

• Electronic health records (EHRs) are increasingly vital, especially with new diseases.
• Current EHR systems face security risks like data breaches and attacks.
• Decentralized storage is needed due to dispersed healthcare data.

Purpose of the Study:

• To introduce AguHyper, a secure EHR storage and sharing solution.
• To leverage blockchain technology for enhanced healthcare data security and integrity.
• To address limitations in existing research on blockchain applications in healthcare.

Main Methods:

• Developed AguHyper using a permissioned blockchain framework with Hyperledger Fabric.
• Utilized InterPlanetary Distributed File System (IPFS) for encrypted off-chain data storage.
• Incorporated CouchDB and the Raft consensus mechanism for performance evaluation.

Main Results:

• AguHyper demonstrates a decentralized architecture, eliminating single points of failure.
• The system ensures transparency and enhances security, privacy, scalability, and data integrity.
• Performance assessments show competitive throughput and latency compared to existing studies.

Conclusions:

• AguHyper provides a robust and secure solution for EHR management.
• Blockchain technology offers significant potential for improving healthcare data security.
• The study contributes valuable insights into practical blockchain implementation in healthcare.
