A blockchain-based healthcare data marketplace: prototype and demonstration

Area of Science:

• Health Informatics
• Blockchain Technology
• Data Management

Background:

• Fragmented healthcare data hinders comprehensive analysis and utilization.
• Existing healthcare data transaction models face challenges in security, transparency, and efficiency.
• A need exists for a secure and efficient platform for individuals and companies to transact healthcare data.

Purpose of the Study:

• To develop a blockchain-based business-to-consumer (B2C) healthcare data marketplace.
• To ensure secure and transparent transactions of healthcare data among individuals, companies, and marketplaces.
• To create a framework for gathering and analyzing fragmented healthcare data.

Main Methods:

• Designed a blockchain architecture for the healthcare data marketplace.
• Developed the marketplace using Panacea, MySQL 8.0, JavaScript library, and Node.js.
• Created mobile and web applications for user interaction and data management.

Main Results:

• The healthcare data marketplace demonstrated efficient transaction data query execution within 1-2 seconds.
• The system processed approximately 9.5 healthcare data queries per minute across three tested scenarios.
• The developed applications provided a functional platform for healthcare data exchange.

Conclusions:

• Blockchain-based healthcare data marketplaces show compliance in data collection processes.
• The developed marketplace effectively addresses time and place limitations in data gathering.
• This framework facilitates the analysis of fragmented healthcare data, offering significant potential for research and application.
