A New Watermarking Sequence Generation Algorithm for Collision-free Digital Watermarking

摘要

A new algorithm for watermarking sequence generation is proposed, allowing collision-free robust watermarking using correlation-based watermark detector with known detection threshold. The proposed algorithm provides considerably large number of distinct watermarking sequences which makes it more robust to a brute-force watermark extraction attacks (compared to known algorithms for watermarking sequence generation). Also, proposed algorithm fulfills the set of application-specific requirements motivated by needs of watermarking scheme computational effectiveness, robustness etc.
