Watermark display method and device, computer equipment and storage medium

Abstract

The invention relates to a watermark display method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring duration information of video content and initial coordinates of watermarks, selecting watermark switching time points of which the number is positively correlated with a preset watermark position switching frequency in a time period corresponding to the duration information, obtaining a watermark switching time point sequence, determining coordinate values of watermarks corresponding to the watermark switching time points, obtaining a watermark switching coordinate sequence, performing coordinate switching on a watermark from an initial coordinate according to a watermark switching time point sequence and the watermark switching coordinate sequence in a video content playing process, displaying the watermark, and when the watermark and a visual element of a single-frame image corresponding to a watermark switching time point are detected to be shielded, displaying the watermark in a blank area. The dynamic watermark data generated by the method is high in security.

Description

technical field [0001] The present application relates to the technical field of multimedia data processing, in particular to a watermark display method, device, computer equipment and storage medium. Background technique [0002] Watermarking technology is an information hiding technology that can embed copyright information, identification information, images and other information into carrier images such as video, audio, pictures, and text in a visible or invisible manner. When embedding invisible watermark information, since the embedded watermark information is lower than the minimum granularity detection range that the human visual system can bear, it can be used to prove the source of the work on the one hand, as evidence for infringement prosecution, on the other hand, it can also By detecting and analyzing the watermark of digital works, the integrity protection of works is realized. [0003] At present, the existing watermarks added to videos are basically static,...

Problems solved by technology

[0003] At present, the existing watermarks added to the video are basically static, and once this static watermark is generated, it will not change again, and because the position of the static watermark is fixed, the watermark can be covered by the video content, and There may be cases where the video content is blocked, and it is easy to be imitated and forged technically, and cannot effectively prevent counterfeiting and anti-theft recording

[0004] In summary, the existing video watermarking scheme has the defect of low data security
