Sound demos for Eveguard

EveGuard is an innovative software-based defense mechanism against vibrometry-based side-channel eavesdropping attacks (SSEAs). We provide audio examples with and without Eveguard.

Our experimental setting is as below:

Scene
  • Original audio (OA) refers to the raw speech signals.
  • Perturbed audio (PA) refers to the speech signals perturbed by Eveguard.
  • Raw-recovered result refers to the raw audio signals derived from mmWave signals.
  • Enhanced result refers to the audio signal in which raw-recovered result is enhanced by SSEA.
