QuoteResearchers 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.

RFID tags have been called "wireless bar codes" -- though they hold more data -- and are commonly used for things like ID badges or keeping track of inventory in a retail store or hospital.

Though RFID tags are usually read by a wireless data reader, the proposed DVD-protection scheme would make no use of RFID's wireless capabilities.

Rather, the researchers are interested in the ability to write data to the tags, which can't be done on a DVD once it's been burned.

Here's how the system might work:

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. The system would require consumers to buy new DVD players with RFID readers.

Gadh said his research group is trying to address the problem of piracy for the movie industry.

"Content owners would like to have extremely tight control on the content so they can maximize revenue," Gadh said. "Users want to move stuff around."

Gadh said the proposed system is "absolutely" more restrictive to users than anti-copying methods already used to protect DVDs.

"By definition this is a restrictive form (of digital rights management)," Gadh said.

Gadh said he could not reveal specifically how the system would work, as it is still in the research stage. A prototype will be available by the end of the summer, he said, and at that point, it will be shopped around to movie studios and technology companies.

"I don't know quite what is going to work in the real world," Gadh said.

Most DVDs are already encrypted with an anti-copying mechanism called Content-Scrambling System. The encryption has been broken, however, and programs to descramble DVDs can be found all over the internet.

DVDs are also "region coded" so that discs sold in the United States, for instance, cannot be played in the United Kingdom. The region coding gives the movie studios control over where and when films are released on DVD.

Ed Felten, a computer science professor at Princeton University, called the proposal the "limit of restrictiveness."

"I think people would find it creepy to give their fingerprint every time they wanted to play a DVD," Felten said. "It's hard to think that would be acceptable to customers."

He said it seems unlikely that people would buy new DVD players with RFID readers in order to purchase DVDs that are less functional.

Privacy advocates have expressed concern about RFID technology because the tags can tie products to individuals, potentially without their knowledge.

Seth Schoen, staff technologist at the Electronic Frontier Foundation, said it's unlikely this DRM plan will be any more effective than others preceding it.

"It only requires one person to break it," Schoen said.

Schoen said this is the "smart cow problem": Once one of the cows opens the gate, the others will follow.

I don't think the market is anywhere near a point to be considering this option, as it's obviously way intense.  There is a better solution than this.

The worst case scenario for Hd-DVD copyright protection discussed by DVDFile is kind of scary, too. And interestingly the porn industry has a large say in the matter; being against these type of measures in order to protect buyers anonymity.

Something has to be be done, I agree but at the same time I worry about cinemas. Often in these discussions I'm thinking of that report posted in The Incredibles thread from Brad Birds "State of Cinema" key-note speech. Obviously studios arent going to have parallel cinema and dvd releases for blockbuster movies but I'd be really upset to see Birds theory of home-release only for smaller titles, become a reality.

As much as I scoff at the "revolution" of digital cinematography, I do hope that digital projection brings about the simaltaneous worldwide release of films. My own forays into piracy have been soley to see a film that would be released in the UK 3 months after the US, such as The Life Aquatic. Hopefully this would have a knock-on effect with DVD releases - finally bringing an end to region coding. I'm quite happy to keep national certification boards though - I think the BBFC here do an excellent job.

I'd have to pull a Van Damme from Double Team if my dad wanted to watch one of my DVDs.

How would they handle rental copies?

Don't be a fool... you know people only pirate movies and no one really rents movies anymore.

Oh.

What a stupid idea.

Just.. don't buy the player. Solves that problem.

I thought the problem was the DVD's wouldn't play on more than one player... is it a hardware thing, and not a DVD manfucaturing thing?
