Acoustic face liveness detection

Our patented technology can detect whether someone is trying to impersonate someone else’s identity by presenting a falsified biometric face in the form or a 2D face photograph or a replay video. The face liveness detection is achieved by projecting imperceptible ultrasound signals via the phone speaker. Based on the reflected audio and video signals, we can detect whether it’s a live person’s face or spoof (photo or video replay).
