A Robust Visual-Audio Stream Watermarking Scheme for Video Protection

Abstract

Watermarking techniques are modern and strong methods of copyright protection for authors and companies as well as for ensuring the authority and identification. They hide the company's motto or policy of using for any digital content that exchanged via the internet. Various requirements are needed to embed the watermark in digital media like transparency, capacity, security and robustness against attacks. However, applying watermark on video, with visual and audio stream parts, is still a resource of concern for scientists and interested people to ensure the integrity of the whole video and guarantee that no manipulation was made on the video. In this research, a system is presented for video copyright protection taking into account its integrity and achieving all requirements in watermarking. The system will embed the watermark in both audio and visual streams allowing the transparency control in the watermarked video. Comparing to previous works, our experimental results showed better performance under the terms of robustness against attacks.
