Fast video watermark embedding and extracting method and system, equipment, medium and terminal

Abstract

The invention belongs to the technical field of information security, and discloses a fast video watermark embedding and extracting method and system, equipment, a medium and a terminal, and the fast video watermark embedding and extracting method comprises two processes of embedding a video watermark and extracting the video watermark. The video watermark embedding method comprises the following steps: screening key frames of a video to be embedded with a watermark; carrying out watermark binarization; embedding the watermark in each to-be-embedded key frame; replacing the original video frames with the key frames embedded with the watermark, and integrating the frames into a video containing the watermark. The video watermark extracting method comprises the following steps: screening key frames of a video of which the watermark is to be extracted; trying to carry out watermark extraction on each initial key frame to be extracted; determining whether a watermark sequence to be extracted is an illegal sequence or not; and performing secondary voting on the sequence in a list to be voted to improve the extraction accuracy so as to obtain a final extracted watermark sequence. According to the method, watermark operation can be rapidly and stably carried out, a reliable basis is provided for copyright protection and infringement tracing, and practical application is facilitated.

Description

technical field [0001] The invention belongs to the technical field of information security, and in particular relates to a fast video watermark embedding and extraction method, system, equipment, medium and terminal. Background technique [0002] In recent years, with the continuous development of Internet technology and applications, like traditional physical assets, digital assets such as pictures, videos, audios, etc. have also entered various fields of people's daily life. These data can be downloaded and easily modified and illegal. Misappropriation, and can be easily redistributed or commercialized on the Internet. As more and more people hold digital assets, how to effectively protect the intellectual property rights of digital asset holders has become an important problem that plagues the society. The vital interests of digital asset holders are often difficult to detect and store evidence. [0003] Aiming at the above problems, digital watermark technology has be...
