Digital Watermarks
by 
John F. Letchford
As traditionally used, “watermarks” are embedded text or images on a work of authorship, photograph or the like that identifies the author of the work. Their modern equivalents, “digital watermarks,” are used to fingerprint electronic media such as photographs, music and movies. Digital watermarks should be considered mandatory for artists and others who routinely post content on the Internet.
