Dick Margilus has a good idea for copy protection of books and magazines--a means of rendering scanners and copiers incapable of copying pages. Click here to read all about it (and remember: you saw it there first).
I've been wondering whether some new material or form will make books uncopyable. There was a time that the price for copy equipment (and, for that matter) printing equipment discouraged copytheft. The labor that had to go into the effort also dissuaded potential book thieves (imagine standing at a photocopier to copy a 500-page book).
Perhaps a material that degrades over time will be tried in lieu of paper.
