🔐 QR Maze CAPTCHA - 3-Factor Authentication System

A revolutionary CAPTCHA system that combines QR codes, pattern-based verification, and cryptographic security to create a robust 3-factor authentication mechanism.

🚀 Overview

QR Maze CAPTCHA transforms traditional bot detection into an engaging, secure authentication process. Users scan a QR code, solve a visual maze pattern, and generate a cryptographic one-time pad - all in one seamless flow.

✨ Features

• 🔗 QR Code Integration - Mobile-first scannable authentication
• 🎯 Pattern-based CAPTCHA - Intuitive maze-solving interface (Bob to Alice)
• 🔐 Cryptographic OTP - One-time pad generation from user patterns
• 📱 Mobile Optimized - Touch-friendly pattern lock interface
• 🛡️ 3-Factor Security - QR possession + Human cognition + Cryptographic proof

🎯 How It Works

3-Factor Authentication Flow:

1. Factor 1: QR Code Possession

   • User scans QR code with mobile device
   • QR contains encrypted session data and destination URL

2. Factor 2: Cognitive CAPTCHA

   • User solves maze pattern from Bob 👦 to Alice 👩
   • 4x4 grid with pattern lock interface
   • Proves human presence through spatial reasoning

3. Factor 3: Cryptographic Verification

   • Pattern solution generates unique cryptographic seed
   • One-time pad created combining pattern + session data
   • Secure session established for destination access

🛠️ Technical Implementation

Security Features:

• One-Time Pad Cryptography - Pattern-based key generation
• Session Binding - Prevents replay attacks
• Pattern Complexity - Minimum path length requirements
• Mobile-First - Optimized touch events and responsive design

Pattern Generation:

// 4x4 grid with adjacency checking
const gridSize = 4;
const minPathLength = 5;
// Path data becomes cryptographic input
