A NOVEL REAL-TIME VIDEO DIGITAL WATERMARKING ALGORITHM
This paper proposed a novel video watermarking scheme based on MPEG-4 compression standard. For the Intra frames (I-framcs), we use a gray image as watermark. The most major difference between the traditional method and the novel scheme is that it need not embed the watermark image into the original public image. Instead, extracting the feature of the I-frames, thus we can gain an ownership map according to the feature of the I-frames and the watermark image. When piracy happens, the copyright owner can reveal his right via the ownership mapping and the feature of the suspected image to extracting the watermarking. For the Inter frames (P-frames), we choose partial motion vectors to embed the watermark. According to the experimental results, the proposed methods are efficient, real-time, blind and robust.
