Anti-Spoofing and Mask-Supported Face Authentication Using mmWave Without On-Site Registration
- Published
- Record updated
Summary
The paper presents mmFace, a face authentication system that scans a face with a commodity millimeter wave radar moved along a set trajectory. The reflected signals carry facial biometric and structure features, which support liveness detection and authentication, and the system still works when users wear masks. To avoid on-site registration, the authors propose virtual registration using cross-modal transformation from photos to mmWave signals.
