RFID To Track Play of DVDs And CDs?

      That'll be important to protect you from the prying eyes of the media conglomerates as they STAND IN YOUR FRONT YARD TO READ THE TAG THAT CAN'T BROADCAST ALL THAT FAR. Because it's not like you could look out your window to see anybody close enough to snoop an RFID tag in your living room.

      Give me a break. You yahoos sit here day after day praising places like PirateBay which encourage companies to take these kind of measures and then you whine when they do it. When will you just admit that all you folks want is something for nothing because you can get it?

      Maybe do yourself a favor and encourage your fellow slashdotters to stop enabling these people by defending and participating in thievery. If you don't like the business practice, don't patronize the business. It's really a very simple economic principle. If the majority disagrees with you, then they don't mind this "intrusive" new "feature" and you're SOL because that's dollar voting at work. If they don't know, educate them.

      But, no, Slashdot uses its position and its user base to encourage and excuse piracy instead, ensuring that this type of behavior will continue in an arms race between greedy businesses and common theives into the forseeable future.

      More to the point, how is embedding an RFID chip in the disc going to prevent people playing region-encoded discs outside of their regions?

      Correct me if I'm wrong, but aren't region-encoded discs already... well... region-encoded?

      Either people buy legit US/Japanese/whatever players (which you can't guard against with RFID chips), or they get their existing player chipped to bypass the whole region-protection mechanism - is there any reason to think this isn't going to work with the new RFID players, too?

      Of course, if the DVD players refuse to play unRFIDed discs then they'll be a bit useless for all the existing DVDs out there (nothing like breaking backwards-compatability to hurt a new product). If the RFIDed DVDs have some kind of (data) flag on the disc to turn RFID-checking it on it's liable to be trivial to reverse-engineer or omit the flag when copying the disc, too.

      Even if it does somehow "eliminate optical disc piracy in the entertainment and IT sectors", does anyone else think it's wonderful how they've finally managed to do it just about the time that broadband and bittorrent have made "optical disc" piracy obsolete, even in the mainstream?

    3. Re:Are they trying to encourage piracy by Turken · · Score: 4, Insightful

      Why bother killing the chip? Couldn't a person just use the rfid technology against the machine? In another post around here, it was mentioned that the player may have a "check" chip embedded somewhere in the case to make sure that the player's rfid reader is working properly, and optical bits on the disc to make sure the reader looks for a chip.

      So, what I'm wondering is why not just cut a working rfid tag from a disc and stick it right in the case next to the reader? Then, no matter what disk you put in the player, if the player looks for a chip it will find one.

      Even if there is an optical bit on the disc telling the chip reader what specific response to look for, I'm willing to bet that the chip reader will have some sort of generic pass code that can be sent to it (used for debugging or testing purposes) and it will only be a matter of time before some engineers crack the system to make generic rfid chips to place in the player case to bypass the disc-embedded ones.

    This means a new standard, and new players all round. It's no longer a DVD, and I'm certainly not running out and buying a new player for it.

    On another, rather important, note, they mention it for HD-DVD. HD-DVD doesn't even _have_ region encoding, so they can't tell me the disc is from the wrong one; that's why I want HD-DVD rather than Blu-Ray.

Aside from the problems of small popping when the foil in the tag melts, it seems to be a good way of destroying lots of tags.

  5. I don't understand by DrXym · · Score: 2, Insightful
    How does RFID stop you from using out-of-region disks? Are manufacturers expected to put an RFID into each disc that the player can read to validate? What happens for recordable media? What happens if someone whips out their dremel and just disables the RFID? What happens if I lay one of more legitimate discs on top of the player when I try to play an illegal one? What about the millions of players and discs which wouldn't give a damn about playing these "protected" disks? etc.

    This sounds like just another stupid application of RFID. For the all the effort involved it would be simpler to just embed a hidden track and read that.

  6. Long-term impact by tygerstripes · · Score: 4, Insightful
    Okay, so most people - especially the most tech-savvy - won't bother buying an RFID-equipped player at first. However, if the industry enforcers (RIAA, BPI et al) push it hard enough this could well find its way into most players without the average consumer even noticing. It's not a certainty, but a frightening possibility.

    In that event, I have to ask a simple question:

    Will the revenue previously lost to piracy be fed back to the consumer? Will we see cheaper CDs anywhere?

    Of course not. It's basic fucking economic theory that you can charge more if you segregate a market. Piracy be damned, fair-use my arse - this is just a desperate attempt to control the market, which can only lead to higher prices for legitimate, law-abiding consumers.

    NOBODY WANTS REGION CODING. (except the publishers)

    . The people who actally make the films really don't care. They get their royalties if the disc is bought in the US, Europe, Taiwan or anywhere else. They really just want to make a living doing what they love.

    The end users hate region coding. It means they often have to wait, often end up with an inferior version, and basically reduces consumer choice while increasing their costs.

    The manufacturers don't like region coding. It makes their players considerably less popular. They go to considerable lengths to find ways around the region coding requirement. Multi-region is a key selling point of a player to anyone with any interest in importing discs. They're going to do the ame thing to try to get around RFID chips. Or anything else you might like to try. And they're really not going to be happy about having to increase their costs to add an RFID reader. These companies are working on tiny margins. No matter how cheap, RFID readers will eat into this.

    ... I can read it. If it is encrypted and my player can read it, I can still read it. No matter what they try to do, unless they can come up with some sort of scheme where the complete key management is happening over a closed network that your player is mandatorily hooked up to 24/7, there is no way that this will prevent piracy.

    What they will do is make the incentive bigger for criminals to copy these disks, and they make the incentive bigger for curious people to try and hack the protection of these disks. They will also piss the general disk-buying public off by creating disks that will more often not play rather than play.

    let's see, there's an RFID tag in the disk, the player won't play the disk of the RFID isn't correct, now there's a few options

    -legacy disks won't play (people won't like it, but I can see it happening)
    -legacy disks will play, the fact that RFID is needed sits as data on the disk

    both things will be fixable with a programmable RFID chip, provided their code isn't too complicated (which it can't be, since they're delevering the encrypted content, the algorithm AND the key, just obfuscated)
    you can also mod the player (I can see the US outlawing this).

    things that will work only with option 2:
    cracking the disk image before burning it or simply cutting the RFID chip in the player or wrapping it in tin foil.

    It is unlikely that's all that will be available.

    There are always at least one brand that will sell a player without rfid like what happen with dezoned dvd player. In the beginning it was difficult to find one, after a while some brand started to sell some and not it is not even possible to find a player that check zone encoding on dvd.

    Off course the movie studio could use the RFID to store something mandatory to read the DVD. But that would mean making DVD incompatible with the huge park of player already existing. There is no way they will try that at the same time than they try to introduce the next generation of players ( they want people to replace their DVD player by a next generation one, not buy another dvd player )

    The only way this technology would be usefull is if you make a law that outlaw DVD player with the RFID reader, but xxAA have more juicy target for their "buy you own politician puppet" budget.
