Attacking and Design of Real World Fingerprint Watermarking

Digital 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 person. One both strong and easy to create attack that aims to manipulate the Transaction Watermark Messages is called Collusion Attack. Thereby several watermarked copies of the same content are compared in order to detect the positions of the watermark message. One promising solution is given by an advancement of the Transaction Watermarks, the so called Collusion Secure Fingerprints. These are binary codes able to trace back a distributed copy yet after a Collusion attack. However interaction between performance, code length and security
level still provides problems if the code is applied to real world watermarking algorithms. Therefore several theoretical ideas have been discussed. The goal of this thesis is to elaborate these ideas. One possible way could be to apply a modified embedding and detection strategy. This goes along with the creation of new attacks and an evaluation according to a significant testbed.
