Anatomy of Cactus Data Shield

meehawl writes: "This is a good analysis by CDRInfo on the current version of Midbar's Cactus Data Shield. This is the format Universal will use to protect its new audio CDs. It's been reported here already that some DVDs effectively bypass this protection, but this article addresses the specific concerns of how best to backup these protected CDs, and how to extract the music data at high quality for download to a personal MP3 listening device."

    This is really getting old it seems to be a constant battle. They come up with some new means of protection, and we devise a way around it (we as a collective of consumers). They discontinue it, and release a new one, and we work around it again. Besides no matter what they do you can always play it and pipe the sound back in and record it *shrug*. They should just give up and allow people to buy and play the music normally. In the end although there will be some theft they will increase profits becuase I can't imagine anyone will buy these once the word gets out to the general public a bit more. After all who wants a CD you have to fight to play or use in a manner which you have been accustomed when you can jsut buy a good old normal CD. When will they ever learn :-)

      Right now, yes, I agree with you that most people use dedicated CD players. But with the continuing introduction of "convgergence" devices like Sony's PS2, Microsoft's X-Box (and followon products), combined with the ever-increasing number of consumer devices that allow MP3 playback (Aiwa, Phillips, Sony, Pioneer, Yamana, Denon, not to mention scores of lesser-known brands), more and more people are going to have problems enjoying music THAT THEY ARE TRYING TO LISTEN TO IN A LEGITIMATE FASHION!

      Independent analysis of the recording industry have failed to indicate even a single instance of them not turning a profit in any fiscal or calendar year. The RIAA (and some independent analysts) claim lower profits for last year. Hey, guess what, the economy is in the dumper right now! 99% of the companies out there are showing reduced revenue, and many of those have gone from having a profit to showing a loss.

      The RIAA claims piracy is a major problem right now, yet they have never provided a single independent analysis to back up their point. I can understand them wanting to be proactive in protecting their market, but these manipulations do absolutely nothing to prevent the kind of large-scale piracy that impacts their business. The real 'pirates' have equipment that does a bit-level extraction and is used to create new pressing masters that contain all of this wonderful content-control technology. The people inconvenienced by technologies like CDS are the consumers who only want to exercise the same rights, privilidges, and convenience they have had for decades.

    How can they be so stupid as to think that ANY kind of copy protection will ever prevent their music from getting onto the net? Clearly, they think that someone is sitting there repeatedly dubbing a CD again and again every time something is downloaded. Don't they realize that no matter how difficult they make the initial ripping, it only has to be done ONCE to make a billion copies?

      I agree... The content companies need to realize that it is now impossible to regulate access to copyrighted works. No matter how hard they try, they will not be able to prevent people from giving unauthorized access to others.

      But here is the key - access is only part of the value the content companies provide - there are also things like convenience (how easy is it to download one particular song or episode of a TV show?), quality (how good is the download bandwidth?), and atmosphere (you can't download the experience of watching a movie in a theatre, or attending a live concert!). Unlike access, these things can't be transmitted across a P2P network...

      Only once companies wake up to the fact that preventing unlicensed access is a lost game, and start focusing on non-replicable sources of value, will they be able to accept and profit from the internet.

    You can read the mail after it's been irradiated - but forget listening to these CDs in your computer unless you happen to have the right CD ROM in your computer.

    I suspect that computer CDROM players will become "smart" and eventually this copy protection will be thwarted. Expect to see some DMCA lawsuits against the manufacturers that make them though.

    Meanwhile, all computer users who want to play music on their computer get burned.

    One can only hope that there is enough backlash from consumers that raises awarenes to the issues at stake here. The thing that we have to worry about most is consumer apathy.

    If consuners don't take a stand on this crap before long their going to have deposit quarters into their computer every time they want to listen to a song.

  5. thinking ahead by athagon · · Score: 5, Insightful

    One would wonder if the record industries/other persons responsible for greater "security" on CDs/DVDs had thought of this:

    With the current system, the following can be done:

    Person A buys CD1. Person A rips CD1 to disk, and distributes MP3s to Person B. Person B likes said MP3s, and buys CD1 for his/herself.

    With "rip proof" technology (at least, until its cracked), however:

    Person A buys CD1. Person A tries to rip CD1, and fails. Person A tells Person B that CD1 sucks because you can't rip it. OR: Person B can't hear MP3s from CD1, so Person B doesn't know whether or not (s)he should buy it, and possibly decides not to.

    With the current system, yes, the industries stand a greater chance of losing money: but they also stand a greater chance (and, as some statistics have shown, this is the case) of gaining more money; given that the majority of Napster users (apparently, and as I did) used Napster to download a few random MP3s to decide whether (s)he should/should not buy CD1. With rip-proof CDs, however, Person A, B, C... won't be able to listen to MP3s from CD1, and thusly won't know whether or not they want to buy it.

    Synopsis:

    It would not seem wise, at least to me, for the industries to err on the side of greater control, and away from the potential for greater sales. Penny wise and dollar foolish, they say...

      You're right in suggesting that they want enhanced control. But remember, when you listen to your friend's MP3, decide you like and go out and buy it you're making a purchasing decision about whether or not you like the music based upon your friend's opinion and your personal preferences.

      You're not making it based upon the music industry's marketing campaign. The industry pushes select artists that they have an investment in and want to succeed, and they would rather that you made your decisions on what to buy based upon they're selling, not upon what your friends like or what you find appealing.

      The record companies, as subsidieries of media conglomerates, already have influence over TV, magazines, record stores, and radio stations (through direct ownership or payola). What they don't control is whether your friend tells you about a new disc he got and the music on it.

      I'd agree that it may hurt sales, since a lot of records that have become popular have become popular because of word-of-mouth but I think more and more people are such slaves of the media anyway (radio in shower, in the car, in the office, MTV at home, etc) that many people by and large have lost their ability to generate an opinion of their own anyway.

    ...the tighter you squeeze, the more systems (CD sales) will escape between your fingers... well something like that anyway!

    I had bought the new Natalie Imbruglia CD (here in the UK) when it first came out and discovered myself that it was copy protected. I was very annoyed to say the least and managed to return the CD and get my money back. A while later I ordered the unprotected version from BMG and now I have a CD that I can actually listen to.

    There is NO WAY I will intentionally buy any protected music CDs now, or in the future. Music publishing companies will just force copying and distribution of music from these CDs via the channels that they are trying to stop. Duh! why can they not see this?...

    ...Maybe its due to the age old misconception that number of pirated copies equals the number of lost sales! Wrong! Wrong! Wrong!

In the future, if I want to listen to music in the car, then I will have to download it illegally. I will have no choice but to do this. Eventually I will get pissed off with buying useless plastic discs to satisfy my conscience, and they will have lost another revenue stream.

    Message to the industry:

    1) A large proportion of your future customers use MP3. (i.e. anyone under the age of 15 today). By doing this you are forcing them to "go pirate".

    2) A large proportion of your current customers use MP3. You are making enemies of them. This is bad marketing.

    3) It's been said before, and I'll say it again. It takes one copy of a CD to be made digitally, and you've lost. The story showed that this is possible - although it says that the protection is effective, it isn't. They made a copy - and that's all it takes. Even if one person makes a really good analogue transfer, then you've lost.

  11. Those who don't learn from history... by martyb · · Score: 4, Insightful

    "Those who don't learn from history are doomed to repeat it." Back in the late 80's it was all the rage by software manufacturers to copy protect their software. (I still have a copy of Lotus 123 from that era.) Various schemes were used:

    • Bad sector(s) on a floppy disk that needed to be present in the drive for the program to run. The disk could not be copied easily using conventional means, but soon people wrote programs to crack the protection.

      Many customers ran into problems when trying to use a legitimately purchased copy as their system reacted differently than expected to the copy protection. The vendors would add increasingly more complicated schemes that never blocked the motivated copier, but DID interfere with legitimate users being able to use the software on certain systems.

    • Printer port dongle that needed to be present in the parallel port. This allowed unlimited copying of the software, but you couldn't run it unless the dongle was in place.

      There was a time when I had a half dozen of these hanging off the back of my PC (imagine 12 inches of dongles sticking out the back; couldn't push the PC against the wall; major leverage against the connector on the PC, etc.) Besides, each dongle interefered somewhat with the timing of the signal going through it... we had a case where a printer attached to the end of the dongle-chain needed to be powered up for the system to boot.

    • Startup questions that required the user to look up a certain value in the documentation and key it in when prompted by the application.

      The thinking was users could easily copy the software, but photocopying the documentation was a much more difficult task that most "pirates" would not go through the effort of doing. I have a game somewhere that came with a "code sheet" printed on red paper that claimed it could not be photocopied. Truly, it was difficult using the black-and-white copiers available at the time, but I persevered and got a usable, albeit poor contrast, copy. (I feared spilling a coffee on the original and becoming unable to play the game which I had legally purchased.)


    In short, users began to revolt and companies eventually began to recognize they were selling fewer copies of their software as people migrated to using non-copyprotected applications.

    Software vendors learned this lesson the hard way many years ago, yet we now have audio (CD) and video (DVD) treading down the same path. I'm waiting to see how long it takes for them to learn this lesson, too.
