Copy-Protecting Movies
There are several things you can do to give your movies a degree of copy protection nothing that would stop the federal government (or a determined teenager with unlimited time and equipment), but enough to keep honest people honest, and average copiers baffled:
-
You can set a movie characteristic that prevents the movie from being edited or saved by any QuickTime application.
-
You can conceal a movie's URL by embedding it inside a poster movie or inside a decoy movie.
-
You can prevent a movie from appearing in the browser's cache folder.
-
You can deliver your movies as real-time streams.
-
You can encrypt the media.
-
You can combine these methods in various ways.
| Note | Here's a word to the wise. There's a lot of interest in securing movies and, yes, there are a lot of useful tricks, but, no, there is no 100% foolproof method someone can always point a movie camera at the screen or capture the packets as they stream across the network. So far, no encryption scheme has proven to be unbreakable.
