Abstract :
Recent years have witnessed a drastic rise in the number of video and image hosting sites, which provide and distribute image and video content on the Internet. In this context, several digital watermarking techniques have been investigated in order to prevent illegal duplication and distribution of such content. Illegal users in turn attempt to remove digital watermarks from such content, and collusion attacking methods, such as an average value attack, constitute a serious threat to digital watermarks. In previous research, we proposed a mosaic-like reconfiguration scheme for static images to resist average value attacks. The reconfiguration scheme comprises two components: a line clipping part that eliminates seam lines from an original image signal, and a line adding part that adds seam lines to the image signals of the preceding part. In this paper, we adapt this scheme to video signals.
