eHealthChain-a blockchain-based personal health information management system

Area of Science:

• Health Informatics
• Internet of Things (IoT)
• Blockchain Technology

Background:

• Medical IoT devices and connected applications are vital for personalized healthcare.
• Effective Personal Health Information Management Systems (PHIMS) require privacy, security, and user control.
• Existing PHIMS face challenges in integrating diverse medical IoT data and ensuring privacy-aware sharing.

Purpose of the Study:

• To propose eHealthChain, a blockchain-based PHIMS for managing health data from medical IoT devices.
• To design a system prioritizing user control, data security, and seamless integration of health information.
• To demonstrate the feasibility of a blockchain-based approach for enhanced personal health information management.

Main Methods:

• Developed a four-layer architecture for eHealthChain: blockchain, IoT device, application, and adapter layers.
• Utilized blockchain technology for secure and decentralized management of personal health data.
• Implemented a Proof of Concept (PoC) prototype using the Hyperledger Fabric platform.

Main Results:

• eHealthChain architecture effectively integrates data from medical IoT devices and connected applications.
• The system provides users with complete control over their personal health data acquisition, sharing, and self-management.
• The PoC demonstrated the viability of the proposed blockchain-based PHIMS.

Conclusions:

• Blockchain technology offers a robust solution for secure and privacy-preserving Personal Health Information Management.
• eHealthChain enhances user empowerment and data control in the era of pervasive healthcare and medical IoT.
• The proposed architecture and implementation lay the groundwork for future advancements in secure health data management.
