Implementation of a New H.264 Video Watermarking Algorithm with Usability Test.

With the proliferation of digital multimedia content, issues of copyright protection have become more important because the copying of digital video does not result in the decrease in quality that occurs when analog video is copied. One method of copyright protection is to embed a digital code, "watermark", into the video sequence. The watermark can then unambiguously identify the copyright holder of the video sequence. In this paper, we propose a new video watermarking algorithm for the H.264 coded video with considering usability factors. The usability testings based on the concept of Human Computer Interface (HCI) have been performed on the proposed approach. The usability testing has been considered representative for most image manipulations and attacks. The proposed algorithm has passed all the attack testings. Therefore, the watermarking mechanisms in this paper have been proved to be robust and efficient to protect the copyright of H.264 coded video. [ABSTRACT FROM AUTHOR]
