🛡️ Zero-Knowledge Proof Badge

📌 Project Description

Zero-Knowledge Proof (ZKP) Badge is a smart contract that issues badges as NFTs to verified users without revealing any sensitive information. The contract leverages ZKP principles and AI-powered fraud detection to ensure secure and privacy-preserving credential verification.

🚀 Features

🔐 Privacy-Preserving Badge System

• Issues NFT-based ZKP Badges for verified users without exposing personal data.

• Uses Zero-Knowledge Proofs (ZKPs) to authenticate users off-chain while storing only verification results on-chain.

🤖 AI-Powered Verification & Fraud Detection

• AI-based Identity Verification: Uses AI models to detect deepfake attempts and fake identity proofs before issuing verification.

• Behavioral Analysis: AI monitors suspicious patterns (e.g., multiple verification attempts) to prevent Sybil attacks.

• Anomaly Detection: Machine learning helps detect irregular badge claims and unauthorized activity.

🔄 Automated Verification with AI

• Document Analysis: AI scans and validates user credentials (e.g., government IDs, certificates) before allowing badge minting.

• Facial Recognition: AI-powered identity matching with liveness detection ensures only real users get verified.

• Adaptive Learning: The AI model continuously improves based on previous verification attempts.

🌐 Interoperable & Decentralized

• Deployable on Ethereum, Polygon, BNB Chain, and other EVM-compatible networks.

• IPFS-based decentralized storage for proof metadata.

🛠️ How It Works

1. User submits credentials (ID, document, or biometric data).

2. AI model verifies authenticity (detects fraud, deepfakes, and inconsistencies).

3. ZKP system validates credentials off-chain.

4. Smart contract mints a ZKP NFT Badge if verification is successful.

5. Users can use their badge to prove their status without revealing details.

🔥 Use Cases --> Web3 Identity & Reputation: Users can prove their expertise or qualifications without revealing private info. --> Access Control: Restrict access to DAOs, events, or platforms based on badge verification. --> Credential Verification: AI-enhanced ZKP badges can represent KYC-verified individuals or certified professionals.
