🛡️ ThaiScamBench (World Class Edition)

The Gold Standard in Thai Scam Detection & Prevention

AI-powered scam detection system for Thai language messages and bank slip images, featuring adaptive learning and crowd-sourced threat intelligence.

🏦 4-Layer Image Detection System

Advanced bank slip verification with 70%+ risk reduction for genuine slips!

How It Works

1. 🔤 Text Analysis (25% weight)

   • OCR extraction via Google Vision API
   • Keyword pattern matching
   • AI classification (Gemini/GPT)

2. 👁️ Visual Forensics (15% weight)

   • Error Level Analysis (ELA)
   • Metadata examination
   • Clone detection
   • JPEG compression analysis

3. 🏦 Slip Verification (40% weight)

   • ✅ Bank name detection (14+ Thai banks)
   • ✅ Account format validation
   • ✅ Amount sanity checks
   • ✅ Date/time format verification

4. 📱 QR Code Validation (20% weight) [NEW]

   • 🔍 PromptPay Decoding (EMVCo Standard)
   • 💰 Amount Cross-Check (QR Payload vs OCR Text)
   • 🛡️ Critical Risk Logic: QR Mismatch = Immediate Flag 🚩

Smart Fusion Algorithm

if qr_valid:  # QR Amount matches OCR exactly
    trust_score += 0.2
    final_risk = 0.0 # High Confidence Safe
elif qr_mismatch:
    final_risk = 1.0 # Critical Risk (Tampering Detected)
