RFID Plan for Copy-Protecting DVDs

(Wired) - Researchers in Los Angeles are developing a new form of piracy protection for DVDs that could make common practices like loaning a movie to a friend impossible.

University of California at Los Angeles engineering professor Rajit Gadh is leading research to turn radio frequency identification, or RFID, tags into an extremely restrictive form of digital rights management to protect DVD movies.

At the store, someone buying a new DVD would have to provide a password or some kind of biometric data, like a fingerprint or iris scan, which would be added to the DVD's RFID tag. Then, when the DVD was popped into a specially equipped DVD player, the viewer would be required to re-enter his or her password or fingerprint.
