IntelliHealth is a decentralized Electronic Health Record (EHR) system designed to enable secure, patient-centric medical data management using blockchain technology and decentralized storage.
The project explores how blockchain can be used to improve data integrity, access control, auditability, and trust in healthcare information systems.
Traditional EHR systems rely on centralized architectures, which introduce risks related to data breaches, unauthorized access, and lack of transparency. IntelliHealth addresses these challenges by combining blockchain-based access control with off-chain decentralized storage for medical records.
The system allows patients to retain control over their health data while enabling authorized healthcare providers to access records securely and transparently.
- Patient-controlled access to medical records
- Blockchain-based authorization and auditability
- Secure off-chain storage of medical data using IPFS
- Backend services for record management and access workflows
- End-to-end system integrating backend, blockchain, and storage layers
The system is designed as a full-stack application composed of the following components:
-
Client
User-facing application for interacting with medical records and managing access permissions -
Server
Backend services responsible for application logic, APIs, and metadata handling -
Blockchain Layer
Smart contracts used to enforce access control policies and maintain immutable audit trails -
Decentralized Storage
Medical records stored off-chain using IPFS, with on-chain references for integrity verification -
Backend: Python (Django)
-
Frontend: Web-based client application
-
Blockchain: Ethereum smart contracts
-
Storage: IPFS
-
Database: Relational database for metadata
Academic and research-focused prototype developed to study secure, decentralized healthcare data systems.
The implementation prioritizes design, correctness, and system integration over production deployment.
