Abstract
The growth of networked multimedia systems has
magnified the need for image copyright protection. One
approach used to address this problem is to add an invisible
structure to an image that can be used to seal or mark
it. These structures are known as digital watermarks. In
this paper we describe two techniques for the invisible
marking of images. We analyze the robustness of the watermarks
with respect to linear and nonlinear filtering,
and JPEG compression. The results show that our watermarks
detect all but the most minute changes to the image.
