Here's an interesting bit of news. According to an article at vnunet.com, companies like Ritek and U-Tech are working on a way to embed RFID chips into DVD's. These chips would then be used to track the discs as they make their way to store shelves as well as a way to prevent illegal copying.
DVDs will soon be tracked with embedded radio transmitter chips to prevent copying and piracy, according to the company which makes movie discs for Warner, Disney, Fox and other major studios.
The technology, which can also be used for Blu-Ray and HD-DVD discs, will allow movie studios to remotely track individual discs as they travel from factories to retail shelves to consumers' homes.
Home DVD players will eventually be able to check on the chip embedded in a disc, and refuse to play discs which are copied or played in the 'wrong' geographical region, the companies behind the technology expect.
While this is a great way to track DVD's, I don't see it as a good way to prevent piracy. RFID chips can be disabled or "zapped" using devices like a modified camera. If you'd like to read more, the entire article can be found here.
