MediLedger

MediLedger is a proof-of-concept application that demonstrates secure, permission-based storage and retrieval of healthcare documents using blockchain technology. It simulates decentralized access control, immutable logging, and document integrity verification through a custom-built blockchain implemented in Python. A detailed explanation of the system’s architecture, design rationale, and implementation is provided in the accompanying Research paper & Presentation

Abstract

The secure and efficient retrieval of patient health documents remains a significant challenge within contemporary healthcare systems, where concerns regarding privacy breaches, transparency limitations, and data interoperability persist. This study presents a theoretical framework that utilizes blockchain technology to address these issues related to access to patient health documents, based on a secure and decentralized system design. The proposed framework utilizes the inherent immutability of blockchain and the automation capabilities of smart contracts to ensure secure data access, enhance privacy protocols, and provide transparent audit trails. By concentrating on the architectural design and its theoretical underpinnings, this research establishes a foundation for future implementation and evaluation of the framework’s efficacy. The paper outlines the system’s key components, including access control mechanisms, data storage strategies, and user interaction protocols, offering a structured blueprint for researchers and practitioners seeking to explore the potential of blockchain in transforming healthcare data management practices.
