Build a Blockchain-Powered Medical Record Management System
Enable tamper-proof and accessible health data storage through blockchain, giving patients control over their records and improving healthcare interoperability.Healthcare data is often fragmented, insecure, and inaccessible across institutions. Blockchain ensures secure, immutable, and patient-controlled storage of medical records, enabling data interoperability and reducing fraud or mismanagement.
Create a decentralized application where patients can store hashes of their health records on-chain, share access with doctors via permissions, and ensure records cannot be altered or accessed without consent.
Patient-Controlled Data Access
Patients own their health records and manage who can access specific documents or summaries.
Immutable Record Hashing
Each record is hashed and timestamped on the blockchain to ensure it hasn't been modified.
Doctor & Hospital Portal
Verified healthcare providers can view or request access to patient records with permission.
Encrypted Storage with IPFS
Medical files are stored off-chain securely using IPFS, with access governed by smart contracts.
Patients upload medical documents that are hashed and stored on IPFS. Smart contracts manage access control, ensuring only permitted addresses can retrieve and decrypt files. Doctors use their verified accounts to access or request documents through the DApp interface.
- Smart Contracts for record registration and access control
- IPFS for encrypted off-chain storage of medical files
- React frontend for patients, doctors, and hospital staff
- MetaMask or WalletConnect for identity and signature verification
- Role-based authentication for healthcare providers
Blockchain
Ethereum or Polygon for permission management and access logs
Smart Contracts
Solidity for access control, audit logs, and permission issuance
Frontend
React.js with Web3.js or Ethers.js
Storage
IPFS for encrypted file hosting, CryptoJS or AES for encryption
1. Create Medical Record Smart Contracts
Write contracts to manage record hashes, access permissions, and view history.
2. Build Role-Based User Interfaces
Design UIs for patients, doctors, and administrators with tailored access and functions.
3. Implement File Hashing & Encryption
Use CryptoJS to hash and encrypt files before storing metadata on-chain.
4. Set Up Secure IPFS Storage
Store encrypted records on IPFS and retrieve them using CID after permission check.
5. Simulate Record Sharing Workflows
Run mock scenarios of patient-doctor-hospital interactions and verify access integrity.
Revolutionize Healthcare Data with Blockchain
Empower patients and providers with a secure, transparent, and decentralized system for managing health records.
