Abstract
The present invention provides methods and apparatus that reverse the notion of the attack process in using intentional image distortion techniques as a means of indelibly marking an original image. It also provides for imparting and removing intentional image distortion to further obscure an embedded invisible watermark. It further provides means for hiding a watermark embedded into a watermarked image. It also provides for imparting distortion on an reference image to form a single level or multilevel caricature of the entire (or part of) the reference image.
