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.. Planning Session. March 19, 2013. Agenda. Topic. Time. Presenter.

Multimedia security has become a major research topic yielding numerous academic papers in addition to many watermarking-related companies. In this emerging area there are many challenging research issues that deserve sustained studying towards an effective and practical system. Multimedia Security Steganography and Digital Watermarking Techniques for Protection of Intellectual Property explores the myriad of issues regarding multimedia security. This book covers various issues including perceptual fidelity analysis image audio and 3D mesh object watermarking medical watermarking error detection (authentication) and concealment fingerprinting digital signature and digital right management.
