RFID Tags for Digital Rights Management 277
mathemaniac writes "RFID Journal is running a story about a group of researchers at UCLA working on a new RFID application that would provide consumers a means of watching DVDs of movies as soon as they hit the theaters. It could also be used to address one of Hollywood's biggest concerns: piracy of digital content. The group is researching a method of using RFID as a tool for digital rights management (DRM), wherein technologies are employed to protect media files from unauthorized use."

At first this looks like DECSS all over again but with the key on an RFID tag.
DeCSS could have worked years ago, when writable DVDs were expensive. But now that I can get a dual layer writable DVD for 3 or 4 bucks, it's too easy to just bit copy the whole damn thing.
RFID tags are even cheaper, more like 30 or 40 cents. The writers themselves are expensive, but if this plan actually goes into action I bet you'll see the price of RFID writers come down real quick, which, hey, at least there'll be good to come out of it.
This technology could conceivably be used for good. Imagine a player with a hard disk as well as a network card. It could auto-download interviews, making-of documentaries and so on as they get released after the DVD ships.
You don't need RFID technology to do that. And without tamper-proof hardware, which is allegedly physically impossible, you're not going to stop piracy, because it only takes one person to break into the device and reverse engineer it.
Of course this is the end of privacy. The RFID tag has to be unique to each copy of the disk, otherwise you could copy it wholesale.
I seriously doubt the RIAA is going to be able to outlaw paying for DVDs with cash.
When the player phones home with the RFID info, they know who bought the disk and maybe even how often it gets played.
I also doubt they're going to force DVD manufacturers to build players that "phone home".

It is true you can take do the line out / line in trick, but you lose fidelity, even if you have an expensive fancypants analog-to-digital converter, which you onboard sound "card" certainly is not.
Once you've digitized a signal (which the studio does for you), the best way to copy is to keep it digital all the way through.

Focus on content, not protecting crap (Score:3, Informative)
The digital format of most films and music released today has led to its increased piracy. The quality of video and audio recordings based in analog technology, such as cassette or VCR tapes, decreases each time an original version is copied.
No, a crappy movie is still a crappy movie, whether it is the first copy or the 1000th copy.
When digital recordings, such as CDs and DVDs, are copied, however, no quality is lost.
You can't lose what you don't have to start with.
The group will also need to develop a system for writing to the tags, a platform for associating DVDs with their purchasers or owners and a means of encrypting the tag data.
Associating a DVD with a particular owner? Right there is baaad news. What is it called, First Sale doctrine or something? I ask because I don't recall the actual name, but you get my point.
Past anti-copy technology has been foiled by simple tricks with markers and clever people cracking weak encryption. I'd bet a dollar or two that this will be no exception.
Note to the **AA: focus more on making the content/experience worth the price of admission/sale/whatever, and people will purchase it. If the public can't enjoy entertainment on their own terms, one of two things will happen:
(1) WE (as in the public) will stop paying for content, or
(2) The aforementioned clever people will break your protection and get the content for free and enjoy it how they wish.
Either way, you lose.

There's a bit more of a moral to that than your version.
