Do you or your company create original digital content? Perhaps music or graphics or video or text? Or combinations thereof. If so, then Seitz suggests that you should be concerned about protecting your content. Especially given the continued rise of peer to peer networks like Kazaa, Morpheus or Napster. These have been responsible for massive unauthorised copying of music. It is also expected that video copying will increase as more users get broadband and computers with bigger disks to store the video.

Seitz explains various methods of embedding a discreet watermark into your content. In such a way that it does not degrade, say, the visual or audio aspects of the content. But so that if you or your agent comes across a file with suspected unauthorised content of yours, then this can be easily verified by checking the watermark.

Of course, someone on the other side can try to remove the watermark. So much of the complexity of watermarking revolves around trying to defeat this.

Seitz offers his book not just to a programmer who might write the watermarking code, but also to the author or artist who creates the content. You can get a valid understanding of the level of current watermarking methods, and their limitations.
