A Blockchain Technology Framework to Enhance Security and Interoperability of Electronic Healthcare Records

This research proposes a blockchain-centered framework designed to address ongoing challenges related to data security, privacy, and interoperability in Electronic Healthcare Records (EHRs).As the healthcare sector increasingly relies on digitalized records, centralized EHR systems face significant risks, including data breaches, privacy violations, and limited compatibility across platforms.This study introduces a decentralized blockchain-based framework, built on Hyperledger Fabric, that leverages cryptographic methods, smart contracts, and distributed ledger technology to ensure secure data sharing, enhanced privacy, and structured access control.The research focuses on the theoretical development and practical evaluation of this framework.Using a design-based approach, the study incorporates a comprehensive literature review, framework development, and empirical testing to assess the framework's effectiveness.Key performance indicators include data integrity, security, system efficiency, and interoperability across diverse healthcare platforms.In conclusion, this framework offers a promising solution for securely managing healthcare data and ensuring interoperability, with potential applications extending beyond the healthcare sector.
