Personal Information Masking Tool 🔒

📌 Overview

This project automatically detects and masks sensitive information (SSNs, Names, DOB, etc.) from scanned ID documents.

⚙️ Tech Stack

• OCR: Tesseract OCR (option: Google Vision API)
• NER: spaCy, HuggingFace Transformers
• Visual Layout: YOLOv5 (future enhancement)
• Image Processing: OpenCV, Pillow
• Backend (future): Flask

🚀 How It Works

1. Detect text regions (YOLO planned, Tesseract fallback used now)
2. Extract text with OCR
3. Identify sensitive info using Regex + NER
4. Mask regions (black, blur, pixelation)
5. Save outputs:
   • Masked image (/outputs)
   • JSON report (/reports)
