Enhancing Healthcare Data Integrity Through Blockchain-Based Master Data Management: An Architectural Framework

Abstract

This technical article explores an innovative approach to Master Data Management (MDM) using blockchain technology, addressing the specific challenges faced by healthcare organizations. It presents a comprehensive solution that combines blockchain with attribute-based encryption, IPFS (Inter Planetary File System), and CP-ABE (Ciphertext-Policy Attribute-Based Encryption) technologies to create a secure, decentralized, and tamper-proof data management system. The article examines current challenges in healthcare data management, including data silos, integration issues, and security vulnerabilities, while proposing a multi-layered architectural solution. The implementation strategy outlines a phased approach, covering infrastructure setup, data migration, and operational monitoring. The article also addresses critical security considerations through blockchain immutability, advanced encryption frameworks, and automated threat detection systems. Furthermore, the article discusses future considerations focusing on scalability and interoperability challenges in healthcare blockchain implementations, providing insights into potential developments and improvements in the field.
