On the Need for Signal-Coherent Watermarks
2006
IEEE transactions on multimedia
Digital watermarking has been introduced in the 90's as a complementary technology for copyright protection. In an effort to anticipate hostile behavior of adversaries, the research community is constantly introducing new attacks to benchmark watermarking systems. In this paper, we present a generic attack strategy based on block replacement. As multimedia content is often highly repetitive, the attack exploits signal's self-similarities to replace each signal block with another, perceptually
