🛡️ CD Blocker

Real-time credit card or sensitive information detection and blurring for live streamers.

🚨 The Problem

• Streamers accidentally show credit cards or any sensitive card-related info on stream → identity theft, financial fraud, career damage.

✨ Solution

An AI-powered relay app that sits between the streamer and YouTube/Twitch, automatically detecting and blurring those sensitive information in real-time before the video ever reaches the platform, or while they stream.

🔧 How It Works

• Gemini detects objects that might be credit cards
• Google Cloud Vision recognizes pattern in those regions
• Pattern matching validates if it's actually sensitive card or related information
• Auto-blur the sensitive area while streaming

🚀 Key Features

• ⚡ Real-time processing (< 300ms latency)
• 🎯 Credit card and sensitive info detection with validation (format checks)
• 🎛️ Streamlined and auto blur intensity
• 📺 Works with any streaming platform

🛠️ Quick Start

pip install -r requirements.txt
python app.py

If you use Google Cloud Vision, ensure your credentials are configured (for example, GOOGLE_APPLICATION_CREDENTIALS pointing to your service account JSON key).

🧰 Tech

• OpenCV
• Google Cloud Vision API
