🔐 Face Recognition USB Locker (Java + Python)

A hybrid security system that locks/unlocks USB drives using face recognition.

This project combines:

• ☕ Java (GUI + USB Control)
• 🧠 Python (OpenCV Face Recognition)
• 📱 DroidCam (IP Camera)

---

🚀 Features

• 🎥 Capture face dataset using phone camera (DroidCam)
• 🧠 Train face recognition model (LBPH)
• 👁️ Real-time face recognition
• 🔐 Automatically lock USB drives when inserted
• 🔓 Unlock USB only after successful face authentication
• 🖥️ Simple Swing GUI
• ⚡ Optimized for low-resource environments (CPU-only, no GPU required)

🏗️ Project Architecture

🔹 Java Side

• Detect USB drives
• Lock USB automatically
• Launch Python scripts
• Read recognition result (AUTHORIZED)

---

🔹 Python Side

• Face dataset collection
• Model training (LBPH)
• Real-time recognition

---

⚙️ Requirements

🐍 Python

pip install opencv-contrib-python
pip install pillow
pip install numpy

---

☕ Java

• JDK 8+
• Swing

---

📱 Camera Setup (DroidCam)

This project uses DroidCam as IP camera.

Example stream:

http://YOUR_IP:4747/video

Make sure:

• Phone and PC are on same network
• DroidCam is running
• URL works in browser

---

▶️ How It Works

1. 📸 Recon (Collect Faces)

• Click Recon
• System captures ~30 images from camera
• Saves in:

dataset/

---

2. 🧠 Train Model

• Click Train
• Model saved in:

trainer/trainer.yml

---

3. 🔐 USB Protection

• When USB is inserted:

  • Automatically detected
  • Immediately locked (readonly)

---

4. 👁️ Face Recognition

• Click Disable Protection
• Python starts recognition
• If face is valid:

AUTHORIZED

---

5. 🔓 Unlock USB

• Java reads AUTHORIZED
• Executes unlock script
• USB becomes accessible

---

🧠 Technical Highlights

• LBPH algorithm for efficient face recognition
• CPU-only execution (no GPU required)
• Java ↔ Python communication via process output
• Real-time USB monitoring

---

💻 System Specs (Tested On)

⚠️ This project was built and tested on a very low-end machine:

• CPU: Intel Core 2 Quad Q8300 @ 2.5GHz
• RAM: 4GB
• GPU: None (CPU-only, no VRAM)

✔️ Despite that, system runs successfully

---

⚠️ Important Notes

• Requires Administrator privileges (for diskpart)

• Works best with:

  • Good lighting
  • Stable camera connection

• USB locking uses .bat scripts + PowerShell

---

💡 Future Improvements

• Multi-user recognition
• Auto-lock when face disappears
• Better UI feedback
• Remove .bat → direct Java control
• Logging system
