....it is ensured that a better extracted watermark is always obtained. Experimental results confirm that our watermarking scheme can be robust to different kinds of attacks, including combined ones. In addition to the tests of several attacks in this paper, extensive tests had also been done in [4], 7] The remainder of this paper is organized as follows. In Section II, we shall introduce the random modulation technique commonly used in conventional watermarking methods and propose a new modulation strategy called complementary modulation to satisfy the robustness requirement. In ....

....An example of these distortions is given in figure 7. StirMark can also perform a default series of tests which serve as a benchmark for image watermarking [107] Digital watermarking remains a largely untested field and very few authors have published extensive tests on their systems (e.g. [112]) A benchmark is needed to highlight promising areas of research by showing which techniques work better than others. One might try to increase the robustness of a watermarking system by trying to foresee the possible transforms used by pirates; one might then use techniques such as embedding ....

....of content owners who have to decide how much quality degradation to tolerate in return for extra protection o#ered by embedding a stronger signal. II. A benchmark Digital watermarking remains a largely untested field and very few authors have published extensive tests on their systems (e.g. [13]) A benchmark is needed to highlight promising areas of research by showing which techniques work better than others but also to be able to compare quickly new algorithms which appear in the literature. Until now most papers have used their own series of tests, their own pictures and their own ....
