Document Type and Number:
WIPO Patent Application WO/2022/142521
Kind Code:
A1
Abstract:
A liveness detection method and apparatus, a device, and a storage medium. The method comprises: obtaining multimedia data to be detected; extracting audio data and video data of the multimedia data; performing speech recognition on the audio data to obtain speech information, and performing lip language recognition on the video data to obtain lip language information; and parsing according to the speech information and the lip language information to obtain offset information between the audio data and the video data, and verifying, on the basis of the offset information, whether the multimedia data is from a living body. The accuracy of liveness detection is significantly improved, an omission rate of liveness detection is reduced, and an error-tolerant rate is provided for some videos of which the audio and picture are out of sync. Thus, the original annotation cost of a large number of videos of which the audio and picture are out of sync is saved.
