Overview

Sentinel-Gate is a multi-modal authentication system that fuses behavioral NFC signals with hand-geometry landmarks. A custom gated fusion network runs in real time on constrained edge hardware, balancing security with sub-100ms responsiveness.

Highlights

  • Custom Gated Fusion Network merging 8 behavioral NFC features with 232 hand geometry landmarks via MediaPipe
  • BiLSTM + Self-Attention encoder achieving sub-100ms inference on CPU-only edge hardware
  • Deployed on Arduino Nano for resource-constrained embedded devices
