BasedAuth

BasedAuth is a blockchain-based system integrating NFT wallets with RFID and barcode-enabled student ID cards, utilizing biometric authentication and zero-knowledge proofs to securely verify transactions.

Features

• NFT Wallet Integration: Links student ID cards to blockchain-based NFT wallets for secure and transparent management.
• Biometric Authentication: Utilizes ZK Face ID for secure facial recognition to verify user identity.
• Zero-Knowledge Proofs: Ensures transaction authorization without revealing sensitive biometric data.
• Smart Contracts: Manages access rights and logs transactions on the blockchain.

How It Works

1. RFID Integration: Student ID cards equipped with RFID are linked to their NFT wallets on the blockchain.
2. Biometric Authentication: The system captures the user's facial biometric data and generates a zero-knowledge proof (ZKP) that confirms the user's identity without revealing the actual biometric data.
3. Transaction Verification: The ZKP is used to sign transactions, ensuring that only the verified user can authorize them.
4. Smart Contract Execution: Access rights and transactions are managed through smart contracts, ensuring secure and transparent operations.

Implementation Details

Prerequisites

• Blockchain Network: Set up a Layer 2 blockchain network supporting smart contracts and NFTs.
• RFID Readers: Deploy RFID readers at key access points on campus.
• Biometric Hardware: Install biometric hardware capable of capturing facial recognition data.

Steps

1. System Architecture Design:

   • Integrate existing RFID infrastructure with the blockchain network.
   • Map out how RFID data interacts with blockchain transactions to ensure data integrity and security.

2. Smart Contract Development:

   • Develop smart contracts on the Layer 2 blockchain to handle features of campus services and permission management for NFTs.

3. Middleware Development:

   • Create middleware to translate RFID scan outputs into blockchain-readable signals to query or initiate smart contracts.

4. User Interface Development:

   • Design interfaces for both administrators and students to manage access rights and view transaction histories.

5. Testing and Optimization:

   • Conduct thorough testing to ensure system reliability and optimize for performance.

6. Documentation and Demo:

   • Document the entire process from RFID integration to blockchain interactions and prepare a live demonstration.

Usage

1. Enroll Users: Register students' biometric data and link their RFID-enabled ID cards to their NFT wallets.
2. Access Services: Students use their ID cards at RFID readers for secure and efficient access to campus services.
3. Transaction Verification: Biometric data is captured and verified using zero-knowledge proofs, ensuring secure transactions.

Benefits

• Enhanced Security: Mitigates risks associated with traditional RFID technology through biometric verification.
• Operational Efficiency: Reduces administrative overhead with automated processes.
• Improved Accessibility: Ensures inclusive access to services for all students.
