Summary
This study introduces a secure blockchain and IPFS system for sharing electronic healthcare records (EHRs). Patients control access to their EHRs, ensuring privacy and efficient data retrieval.
Area of Science:
- Health Informatics
- Computer Science
- Cybersecurity
Background:
- Sharing electronic healthcare records (EHRs) is crucial for healthcare and research.
- Current systems face challenges in privacy protection and secure data exchange.
Purpose of the Study:
- To propose a controllable, secure blockchain-based scheme for sharing EHRs.
- To enhance privacy and efficiency in EHR data exchange.
Main Methods:
- Combined blockchain technology with Interplanetary File Systems (IPFS) for EHR sharing.
- Developed an IPFS-based EHR File System (IEFS) for large file storage and sharing.
- Implemented a Blockchain-based EHR Abstract System (BEAS) for access control using patient public keys.
Main Results:
- Demonstrated secure sharing of EHRs under patient control.
- Confirmed efficient retrieval of EHR files using IPFS technology.
- Validated a prototype system for the proposed scheme.
Conclusions:
- The proposed scheme offers a secure and patient-controlled method for EHR sharing.
- Blockchain and IPFS integration provides a robust solution for healthcare data management.
- Addressed practical issues like key management and doctor interaction.
