The watermark template attack

摘要: This paper presents a new attack, called the watermark template for watermarked images. In contrast to Stirmark benchmark [1-2], this attack does not severely reduce quality of image. stack maintains, therefore, commercial value previous approaches [3-4], it is aim change statistics embedded watermarks fooling detection process but utilize specific concepts that have been recently developed more robust watermarking schemes. The estimates corresponding points in FFT domain and then removes them using local interpolation. We demonstrate effetiveness showing different test cases with available products. approach presented limited domain. Other transformation domains may be also exploited by very similar variants described attack.
