MagLive: Robust Voice Liveness Detection on Smartphones Using Magnetic Pattern Changes
- Published
- Record updated
Summary
The paper presents MagLive, a voice liveness detection scheme for smartphones that targets replay spoofing attacks, where recorded voice is played through loudspeakers to bypass voice authentication. It uses magnetic pattern changes captured by the built-in magnetometer, processed by a TF-CNN-SAF feature extractor with supervised contrastive learning, and reports an average balanced accuracy of 99.01% and an equal error rate of 0.77%.
