The invention provides a method and a device for detecting authenticity of a figure in a video, electronic equipment and a computer storage medium. The method comprises the following steps: acquiringa to-be-detected video; extracting a video key frame and / or a video key segment of a person contained in the to-be-detected video; on the basis of the video key frame and / or the video key segment, adopting at least two authenticity detection strategies to carry out multi-modal information authenticity detection on a person in the to-be-detected video, and obtaining a detection result correspondingto each detection strategy; and based on the detection result corresponding to each detection strategy, determining the authenticity detection result of the person in the to-be-detected video. In thescheme, character authenticity detection is performed from multiple dimensions such as the voice information, the face information, the body movement information and at least two authenticity detection strategies of the character, so that the finally obtained authenticity detection result considers the influence of factors of the multiple dimensions on the authenticity detection result, and the authenticity detection result is more accurate.
Description
technical field [0001] The present application relates to the technical field of multimedia data processing, and in particular, the present application relates to a method, device, electronic equipment and storage medium for detecting the authenticity of characters in a video. Background technique [0002] At present, face recognition technology in video has been widely used in criminal investigation, access control system, camera surveillance, network application, identity recognition, information security and entertainment applications, etc.; based on the development of face recognition technology, more and more forgery technologies Emerged as the times require, hindering the development of face recognition technology. [0003] In the prior art, although there are many methods for detecting the authenticity of people in videos, the detection results of the existing detection algorithms are not ideal. Therefore, it is urgent to provide an accurate method for detecting the a...
