The NCCU research team has successfully published their paper, "GDPR-Compliant Personal Health Record Sharing Mechanism with Redactable Blockchain and Revocable IPFS," in the prestigious international journal IEEE Transactions on Dependable and Secure Computing.

Collecting and storing personal health data has become commonplace in today's IoT-driven world. However, traditional cloud storage solutions often fail to guarantee data integrity, while blockchain's immutability can clash with stringent data privacy regulations like the GDPR. The NCCU team has developed a novel platform integrating redactable blockchain technology with a revocable IPFS to address these challenges. This innovative approach enables users to selectively delete outdated health records while preserving data integrity and traceability, ensuring full compliance with GDPR standards. Additionally, the team's enhanced proxy re-encryption scheme simplifies access control for healthcare professionals, making the system more user-friendly and efficient.

By leveraging these advanced technologies, the proposed solution surpasses traditional blockchain and peer-to-peer file-sharing systems in terms of performance and computational efficiency. This groundbreaking research offers a promising solution for managing personal health records and opens up new avenues for blockchain applications in the healthcare sector. The NCCU research team remains committed to pushing the boundaries of technology and substantially impacting global healthcare.
