Piracy is a major issue in the content business, and although digital technologies raise the efficiency of new content production, pirates also accelerate their piracy. Commercial cameras have become sufficiently good to re-shoot images displayed on screens, and TV monitors are becoming larger with better picture quality; this combination will enable content to be pirated in the home in the near future. Re-shooting with a commercial camera is the ultimate piracy method because there is no engineering way to stop it. We have developed a new watermark method that remains even after images displayed on a monitor have been re-shot. This paper describes the concept and experimental results.
