Dion Boesten, dr. Boris . Škorić. Introduction. Forensic watermarking . is a technique to combat the unauthorized distribution of digital content. Each copy is embedded with an imperceptible and unique watermark. The main challenge in this area is to create codes that are resistant to collusion attacks. In a collusion attack a group of users (pirates) compare their copies and try to create an untraceable copy. Information theory can provide a lower bound on the required code length of a reliable collusion resistant code.. This was the most devastating attack on U.S soil.
