Video counterfeiting detection method and device, electronic equipment and storage medium

The embodiment of the invention provides a video counterfeiting detection method and device, electronic equipment and a storage medium, and belongs to the technical field of generative artificial intelligence. The method comprises the following steps: acquiring a target video, inputting the target video into a time sequence feature extraction network to obtain an initial tampering feature, the target video comprising a plurality of video frames; performing directional time sequence feature segmentation processing on the initial tampering feature to obtain a horizontal tampering feature sequence and a vertical tampering feature sequence; obtaining a diffusion relation matrix according to the horizontal tampering feature sequence and the vertical tampering feature sequence, and performing diffusivity modeling based on the diffusion relation matrix to obtain a diffusion relation measurement matrix; and performing detection based on the diffusion relationship metric matrix to obtain a detection result of the targ
