Watermarking is an accepted technology to discourage illegal distribution of multimedia. Using a traitor tracing scheme such as Transaction Watermarking one is able to trace a distributed copy back to the responsible. Collusion attacks aim to manipulate the Transaction Watermark Messages. Therefore several theoretical approaches have been published to counter such attacks, but it is yet unclear how the schemes behave according to different numbers of attackers. The goal of this thesis is to expand the implementation of an existing approach, programmed in C++, and to analyze and optimize its performance in a large-scaled testbed.
In CASED (Center for Advanced Security Research Darmstadt) collaborate the Technische Universität Darmstadt, Fraunhofer Institute for Secure Information Technology and the University of Applied Sciences Darmstadt in the fast developing field of IT Security. In a unique cooperation, which combines different areas of expertise from these renowned institutions, progressive IT security solutions are researched, developed and implemented into industrial economy: CASED brings together computer scientists, engineers, physicists, legal experts and business economists.
