"Digital watermarking software applications are making their way into the Internet arena. These programs/plug-ins embed information about the author into video, audio or graphics files. This information, when decoded with the appropriate software, can reveal things such as the author's address, terms of use, copyright date, etc. Watermarks are unremovable and unalterable. The information does not degrade with file duplication and does not perceptively disrupt the original data file. For more information regarding digital watermarks, see the articles section"
