The embodiment of the invention provides a living body identification method and device and a storage device. The living body identification method comprises the following steps: prompting an identified to blow air to a screen; collecting the sound waveform data of the identified, identifying a blowing time section and a non-blowing time section according to the sound waveform data; acquiring thevideo data of the identified, identifying the mouth shape of the identified according to the video data; and determining whether the identified is a living body or not according to the matching degreeof the mouth shape of the identified and the corresponding time section. According to the embodiment of the invention, the accuracy of living body identification can be improved.
