This invention discloses a vibration signal-based liveness detection method, device, and storage medium, belonging to the field of facial recognition technology. It addresses the problem that existing AI-synthesized portraits are highly realistic, and injected videos lack borders, moiré patterns, and other characteristics of copied videos, making them virtually indistinguishable from real-time videos captured by physical cameras, thus making existing liveness detection technologies easily bypassed. By controlling the vibration motor of a mobile terminal device to vibrate according to a specific signal, the vibration signal is collected by sensors during the recording of the liveness detection video. The vibration frequency is analyzed to determine whether it matches the vibration generation frequency, thereby confirming whether the liveness video is real-time recording rather than an injection attack. Furthermore, the sound emitted by the motor vibration is collected via a microphone and used as part of the audio input for liveness detection. The sound frequency is extracted during liveness verification and its match with the motor vibration frequency is checked. This assists in liveness detection judgment and improves the security of liveness detection.
