RFID To Track Play of DVDs And CDs?

      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?

      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.
