Abstract

This paper presents a watermarking procedure for MPEG-2 videos based on the use of XML documents. The procedure enables the copyright owner to insert a distinct watermark identifying the buyer within the distributed videos. To increase the security level of the procedure, the watermark is repeatedly embedded into some selected I-frames in the DCT domain at different frequencies and by exploiting both block classification techniques and perceptual analysis. The embedded watermark is then extracted from a video according to the information contained in a protected XML document associated to the video.
