Watermarking scheme capable of resisting attacks based on availability of inserter

摘要

Attacks based on the presence of watermark inserter are easy to perform since they make use of similarity between an original watermark and additionally added ones by using the same inserter and key. In this paper, a novel watermarking scheme capable of resisting inserter attacks is proposed. Watermark signals corresponding to the same key are mutually independent if they are randomly selected using the described technique. Thus the inserter attack is invalidated. Performance of the proposed method is studied, and simulation experiments presented.
