Problem Statement
Sensitive financial and technical screens are vulnerable to unauthorized over-the-shoulder visual eavesdropping.
Proposed Solution
Deployed lightweight YOLO & MediaPipe pose detectors to automatically blur screens when multiple faces are detected.
Key Features
- Instant screen blur trigger upon multi-face detection
- Real-time webcam video stream spatial distance scoring
- Custom threat confidence threshold dashboard
- Zero-cloud local device inference for maximum privacy
System Architecture Flow
Webcam Stream -> OpenCV Frame Capture -> MediaPipe / YOLO -> Screen Blur Trigger
Engineering Challenges
Eliminating false-positive triggers from background poster portraits.
Lessons Learned
Implementing head pose orientation angle filters to distinguish onlookers from active users.
