Toward blockchain based electronic health record management with fine grained attribute based encryption and...

Area of Science:

• Health Informatics
• Computer Science
• Cybersecurity

Background:

• Current Electronic Health Record (EHR) systems suffer from security, privacy, and scalability issues.
• Centralized databases are vulnerable to cyber attacks and data breaches, risking patient data confidentiality.
• Interoperability challenges hinder seamless data sharing among healthcare providers, increasing costs and inefficiencies.

Purpose of the Study:

• To propose an innovative framework integrating blockchain technology and the InterPlanetary File System (IPFS) to address EHR system drawbacks.
• To enhance security, privacy, scalability, and interoperability in electronic health records management.
• To present a secure and efficient solution for modern healthcare infrastructures.

Main Methods:

• Integration of blockchain technology with the InterPlanetary File System (IPFS).
• Utilization of attribute-based encryption for fine-grained access control to medical records.
• Decentralized data storage on IPFS to eliminate single points of failure and enhance resilience.

Main Results:

• The EHRChain solution provides enhanced security and privacy through attribute-based encryption and decentralized storage.
• Blockchain integration ensures data immutability and traceability, reducing tampering risks.
• Performance evaluations demonstrate the framework's efficiency, feasibility, and scalability for EHR management.

Conclusions:

• The proposed EHRChain framework offers a scalable and secure solution for electronic health records.
• Integration of blockchain and IPFS significantly improves data security, privacy, and interoperability.
• This approach has the potential to revolutionize EHR management, reduce operational inefficiencies, and establish a new standard in healthcare.
