Sony's New DRM Technique

skochak writes "Sony has introduced a new DRM scheme. You can burn a CD-R from the original once, but you can't re-burn from that first copy." From the article: "The concept is known as 'sterile burning.' And in the eyes of Sony BMG executives, the initiative is central to the industry's efforts to curb casual CD burning. 'The casual piracy, the school yard piracy, is a huge issue for us...Two-thirds of all piracy comes from ripping and burning CDs, which is why making the CD a secure format is of the utmost importance.'"

      but you have to keep in mind, that the first generation of minidiscs came out long before (in 1992 according to this site: http://www.digit-life.com/articles2/sonymzn1netmd/ ) mp3's were that popular, as they are now.
      i bought my first md (sony's model R30) came out in 1996 - and was a real innovation regarding it's smaller size compared to portable cd-players!
      ok, so you had to reencode to attrac, but: you have to rip a cd alike to get it onto your mp3player of choice! so, IMHO reenconding is not a point to hold against md's...

      but i agree that with sony locking the format, they made it unpopular to big (internet!) communities - and therefore killed the chances of being "the new" state-of-the-art in music-formats.

      Apparently, you haven't been paying attention. MD's hold up to 1GB now and can play MP3's. It's not just standard 74min MD's any more, they can be used for normal digital audio. Originally, of course, MD's played compressed digital audio, but it was a different sort of compression, and you could only fit a cd's worth basically.

  3. Details of First4Internet DRM implementation by Anonymous Coward · · Score: 5, Informative

    The First4Internet CD copy protection technology destroys the registry keys (driver device names) associated with your CD-ROM devices. Then a monitoring app allows or disallows access to the device.

    The monitoring app is buggy. If it stops running or loses your device references, you will have to reinstall windows to make your CD-ROM devices work again.

    Also, by messing with the internal driver properties like this, many apps simply hang or crash the system when trying to access the device.

      Above confirmed. This is exactly why you should disable autoplay (or just hold Shift while you boot).

      Naturally, other than that, it's a partial-mixed-mode CD; first session contains audio tracks with a slightly malformed TOC, and second session contains just data track, which will be autoexecuted in a dumb machine if you don't hold Shift.

      This really doesn't bring anything to the table that hasn't been brought before in terms of basic technique. Additionally, the payload definitely qualifies as malware, and therefore should really be removed by an antispyware, who have traditionally held the grounds of safe removal of malicious software created by companies; or even a competent and ballsy antivirus (surrepetitious install damaging system configuration, no safe uninstall, bundled with shiny features = Trojan horse).

      My suggestion is to use Exact Audio Copy, set up correctly (use Secure mode with NO C2, accurate stream, disable cache) combined with Plextools Professional (set Enable Single Session mode before you insert the disc, and rip at a maximum of 4X) in a Plextor CD-RW drive (ideally the Plextor Plexwriter Premium). You can make a perfect copy of the actual CD-DA audio that way, burn an audio CD-R from the WAV/CUE pair if you wish, and - if you have a modicum of sense and don't wish to keep a disc with a live piece of malware in your CD collection - return it to the shop for a full refund, because hey, it doesn't work in your car/walkman/whatever. Sprinkle on additional this-stupid-CD-broke-my-computer rant should you wish. And release to BitTorrent... a stupid record company that puts malicious software on their CDs frankly deserves everything they get.

    Well basically, because the RIAA has been conducting market research surveys through the taylor group ( http://www.thetaylorgroup.com/ ). They do the survey with a couple hundred people every month to see just how their efforts are doing. Unfortunately for the RIAA, the survey is very poorly structured and since it can take over half an hour sometimes, it gets pretty monotonous. Add to that the respondent not getting paid for their time and the data they collect becomes, well, shit. As if that wasn't enough, the age restrictions on this are that the resp. has to be over the age of 10, with no maximum age (10-18 needs parent permission). They get 10 year olds and 90 year olds that have no idea what the hell theyre talking about (more so the latter) and they're asking all of these people about p2p networks, cd burning, drm, etc...

    Not if anyone but Sony changes it. Sony owns the CD Trademark AFAIK and thus can simply declare the new format the "CD".
    Only if you spell Sony "P-H-I-L-I-P-S", as Philips is the actual owner of the Compact Disc trademark, and is not a record label.

    Philips is serious about maintaining CD compatibility, and has forced the purveyors of incompatiple DRM schemes to clearly label that they are not compatible with the standard.

    No, fair use allows for any use, so long as it is fair. There's some tests to check for fairness, but there is no kind of use that can never be fair (or that always is).

    Fair Use is a legal term. It defines a small number of uses of a copyrighted work that are not considered infringing. Basically Fair Use defines situations where one can use a copyrighted work without requiring the permission of the copyright holder.

    Any use that is not covered by the Fair Use provisions of the various copyright acts is infringing. The Fair Use exceptions are quite well defined, although the major copyright holders enjoy trying to shrink them down. I'm fairly certain that any commerical use is considered infringing.

    I have tested the XCP2 copy protection system on a pre release disc. It will play on CD and DVD players. But it won't work on Macs or under Linux.

    When you play it on a computer or DVD player you are not listening to the CD content but rather low bitrate DRM files squeezed into a 80 mb partition.

    The effect of this is twofold.

    1) The sound quality is crappy.
    2) There is less space on the rest of the disc for the real music (only about 60 minutes!)

    I will *never* buy an XCP2 disc. It installs software automatically when it is inserted into a windows computer. There is no 'OK' or 'I agree' button. It just does it without telling the user, I doubt these discs are legal and I can smell a lawsuit coming if they actually try and sell these trojan ridden discs.

  13. Here's a way to defeat any audio CD DRM crap by brother_b · · Score: 2, Informative

    Get an audio CD burner that ignores SCMS (an old retarded DRM system that sets a no-copy bit on audio CDs) and can use plain CD-Rs that accepts digital input. They can be pricey, though, as they are marketed as pro equipment (the "consumer model" ones you can find at Circuit City and the like typically honor SCMS and require those "audio" CD-Rs). The one I have is a HHB from several years ago. However, it can blast through any DRM brain damage because if a CD player can play to a digital output the recorder can copy it. The resulting copy will be both SCMS free and free of whatever brain dead DRM scheme was used on the original. This copy can then be ripped normally to MP3 or whatever.

    Sure, this can also be done entirely with a PC if you have the correct setup, but as a standalone audio recorder is not a PC no DRM scheme that could cripple a PC can affect it. Also, your copy is better in general since the recorder is designed to be high quality audio equipment.
