Medical Record Management on Blockchain - Project Guide for IT and Computer Engineering
1. Introduction
The Medical Record Management on Blockchain project aims to securely manage and share medical records using blockchain technology. This system ensures privacy, integrity, and accessibility of patient data.
2. Objectives
- Provide a secure platform for storing and accessing medical records.
- Ensure patient privacy and data integrity.
- Simplify data sharing between healthcare providers.
- Reduce administrative overhead in record management.
- Enable tamper-proof audit trails for regulatory compliance.
3. Key Components
3.1 Blockchain Platform
- Use Ethereum, Hyperledger Fabric, or Binance Smart Chain for secure data handling.
- Ensure scalability and compliance with healthcare standards.
3.2 Smart Contracts
- Automate access permissions and data sharing processes.
- Define rules for record updates, retrieval, and sharing.
3.3 User Roles
- Patients: Own and control access to their medical records.
- Providers: Access records with patient consent.
- Insurers and Regulators: Verify records with appropriate permissions.
3.4 Decentralized Storage
- Use IPFS or Filecoin to store large medical data files securely.
- Store metadata and hash values on the blockchain.
3.5 User Interface
- Develop portals for patients, healthcare providers, and regulators.
- Provide features for granting/revoking access and viewing records.
4. System Architecture
4.1 Workflow
1. Patients upload and encrypt their medical records.
2. Data is stored on decentralized storage, and hashes are recorded on the blockchain.
3. Patients grant/revoke access to providers or third parties via smart contracts.
4. Providers access records for treatment or analysis, maintaining an audit trail.
4.2 Data Management
- Store detailed records on decentralized storage.
- Maintain hash values and metadata on the blockchain.
4.3 Access Control
- Implement role-based access via smart contracts.
- Allow patients to manage permissions securely.
5. Development Frameworks and Tools
- Blockchain SDKs: Truffle, Hardhat, or Remix IDE.
- Programming Languages: Solidity, JavaScript, or Python.
- Libraries: Web3.js, ethers.js, or OpenZeppelin.
- Storage: IPFS or Filecoin for decentralized storage.
- Frontend Frameworks: React.js, Angular, or Vue.js.
6. Implementation Steps
6.1 Setup the Blockchain Network
- Deploy on Ethereum, Hyperledger Fabric, or Binance Smart Chain.
