[0003] However, frame loss will inevitably occur during the transmission of the video. When the video frame is lost, the watermark information embedded in the video will also be incomplete. When the watermark is extracted based on the frame loss video, the watermark If the extraction fails, the watermark cannot effectively protect the copyright of the video

Embodiment 1

[0067] figure 1 A flow chart of a watermark embedding method provided in the embodiment of this application, such as figure 1 As shown, the watermark embedding method includes the following steps:

[0068] S110. Obtain a video to be embedded with a watermark;

[0069] S120. Embedding the same-bit watermark value of the watermark into the continuous multi-frame images in the video to be embedded with the watermark.

[0070] specific, figure 2 A schematic diagram of watermark embedding provided for the embodiment of this application, such as figure 2 As shown, the video to be embedded with watermark is obtained by loading data, etc., the video to be embedded with watermark is decoded into YUV data, the Y data in the YUV data is extracted as the image to be embedded with watermark, and a sequence of images to be embedded with watermark is formed. Process the watermark character into a binary watermark, set the watermark bit with a gray value of 0 in the binary watermark to ...

Abstract

The invention provides a watermark embedding method and apparatus, and a storage medium. The method comprises the following steps: obtaining a watermark video to be embedded; and embedding the same watermark value of the watermark into multiple frames of continuous images in the watermark video to be embedded. According to the watermark embedding method and apparatus provided by the embodiment ofthe invention, by redundantly embedding the watermark in the multiple frames of images of the video, after frame loss of the video, the complete watermark can still be extracted based on the multipleframes of images that are redundantly embedded in the watermark, thereby reducing the influence of frame loss on the watermark extraction.

Description

technical field [0001] The present application relates to the technical field of multimedia information security, in particular to a watermark embedding method, device and storage medium. Background technique [0002] With the rapid development of the Internet age, video, as the most intuitive and efficient communication carrier, is facing more and more serious infringements such as piracy and illegal transmission. In order to protect its copyright issues, video watermarking technology has emerged as the times require. [0003] However, frame loss will inevitably occur during the transmission of the video. When the video frame is lost, the watermark information embedded in the video will also be incomplete. When the watermark is extracted based on the frame loss video, the watermark If the extraction fails, the watermark cannot effectively protect the copyright of the video. Contents of the invention [0004] In view of this, the purpose of this application is to provide ...
