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.
