There are three typical types/reasons for watermarking that I can think of:
a) as a signature, so you know the content has not been altered, such as on a check b) as an id, so you can track who distributed copies when they weren't supposed to, such as (conceivably) audio/video at a movie theater c) to render the content less-than-fully-functional, yet sufficient for reviewers, e.g. photographs--you wouldn't want to blow up a review print and put it on your wall or send it on your Christmas cards because it has "Joe's photography" emblazoned across it It isn't clear which, (or if there isn't yet a 4th reason), is the intended application here. Also, this may be problem Y, and not problem X :) /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
