Abstract

The application aims at providing a method and equipment for adding and detecting a video watermark. The method for adding the watermark in a video comprises the following steps: acquiring to-be-processed video information; determining a video frame sequence of a to-be-added watermark in the video information according to the watermark sequence information corresponding to the video information, wherein each video frame in the video frame sequence has corresponding watermark information in the watermark sequence information, and an order relation of two adjacent video frames in the video framesequence is matched with the order relation of watermark information corresponding to two video frames in the watermark sequence information; adding the corresponding watermark information of the video frame in the watermark sequence information on each video frame in the video frame sequence, thereby acquiring the video information added with watermark. Through the method provided by the invention, the attack resistance of the added video watermark is stronger.

Description

technical field [0001] The present application relates to the communication field, and in particular to a technology for adding and detecting video watermarks. Background technique [0002] Digital watermarking is an effective digital product copyright protection and data security maintenance technology. In recent years, digital watermarking technology has made great progress. A video watermark is a digital watermark loaded on a digital video. Video watermarking uses the redundant data and randomness that are common in video data to embed information representing copyright into the original video data, so as to protect the copyright or integrity of digital products and ensure the legitimate rights and interests of copyright owners. [0003] However, with the continuous development of technology, people can use algorithms such as image restoration to remove the video watermark added to the video data. Thereby destroying the integrity of video data and the protection of cop...
