Mitigating Presentation Attacks in 3D Biometric Liveness Systems
How edge neural processing units use multi-spectrum infrared depth sensing to neutralize synthetic silicon mask spoofing.

In high-security physical and perimeter deployments, biometric validation terminals face increasingly sophisticated presentation attacks. Attackers use high-resolution masks, generated video, and synthetic thermal overlays.
System Vector Analysis
- Multi-spectrum SWIR depth verification
- Micro-vascular thermal diffusion mapping at less than 140ms latency
- Hardware TPM 2.0 enclave feature-vector hashing
By processing raw sensor streams on local edge NPUs, Vision Sentinel rejects spoofing attempts before granting physical or logical relay privileges.
