Abstract:

Digital watermarking is a method of embedding identifying information in an image, in such a manner that it cannot easily be removed. An application of watermarking is copyright control, in which an image owner seeks to prevent illegal copying of the image. Commercial systems using such technology are now becoming available. In this paper we point out a number of the problems that watermarking faces as it moves into the real world. We also examine some of the weaknesses in the system of the current leading commercial provider of watermarking technology, Digimarc, and suggest ways of overcoming both sets of problems.
Keywords: Critique of digital image watermarking, copyright protection, intellectual property protection, Digimarc.
