BMG to Test Copy-Protected CDs

By David Worthington | Published July 30, 2001, 7:30 PM

The fight to Napster-proof audio CDs has entered the next round of development. Record industry giant BMG Entertainment is set to begin testing a technology which it hopes will thwart the illegal creation of compact discs. Partnering with SunnComm Incorporated, BMG will deploy its own in-house copyright protection measures along side SunComm's MediaC1_Q Digital Cloaking Technology. SunComm refused to disclose details on the inner-workings of the protection.

SunComm hopes that the exposure it has received from this partnership will lead to industry adoption of its own technology rather than its competitor's offerings. Thus far, no fool proof method of protecting copyrighted material on CDs has been found, and the music industry has gone to great length to block the exposure of flaws in existing copyright technologies.

According to SunnComm President Peter H. Jacobs, the companies "can inhibit illegal duplication of CDs while, at the same time, enhance the consumer experience." Today's press release goes on to say that customers will have drag and drop access to digital music, as well as experience additional features and enhancements – all within a secure environment.

Competing technologies such as Macrovision's SafeAudio, and Verance's content management solutions have the same goals in mind. In spite of its quest for secure music, the Recording Industry Association of America (RIAA) has been accused of blocking attempts to publish technical details that reveal how to circumvent current protection schemes.

In a very public clash, Princeton Professor Edward Felten and The Electronic Freedom Foundation sued the RIAA and other industry groups over alleged legal threats to Felten and his team of researchers. BMG and SunnComm's partnership represents an important step in the cat and mouse game to secure intellectual property rights.

Neither BMG nor SunnComm were available for comment at press time.

Decient movies are available @ asian
streaming sites @ 200-400M per movie.
Shoutcast streams 1,500 channels of mp3's.
700M burnable cd's are 15 cents apiece.
DSL connections are worldwide and getting
faster.
If i can put 2 movies and 3 albums on 0ne cd and
transmit it anywhere on the planet at 60 - 100k sec
(3hours) it means the movie and music industry must figure out the same thing the game designers figured out. The experience
they provide with their data must be so rich and versitile
that people need and want to pay to access the needed data.
As is the data packet (a movie@220M or full cd@60M} is just to
cheap and easy to store and transmit to ever fully protect it.
Not an Ethical Problem here....It's Numerical!!

Come on everyone. If there are any artists please listen. The problem with this entire dilemma is not whether people deserve protection on their work, to keep it from spreading. I am an artist just entering the 'business' and to me, the 'business' itself is the problem. What no one realizes is that because of the ease of distribution of mp3's, music reaches many many times more people, and each artist gathers an even larger audience. I personnally could have never afforded to buy as many albums as I now have due to mp3. But guess what happens when the show comes to town? Im there, paying my 50 to get in and see a guy whose albums I don't own, and whose cover art I've never seen. The truth is, a fan may buy a recording, but music began as an institution of pride for talent, not a business. Make the music because you're proud, not because it robs kids of their allowance. I follow several bands and have never bought an album by some of them. What does this mean? It means I am like many other americans, in love with music, but unable to fund my habit. Mp3 is rebellion, it's time to listen to the audience folks, because we paid for your homes, cars, and shouted at your shows. We give the artists pride, and pay them well for it. Perhaps it is time to give a little back.

Sooo... let me get this straight... we have mp3's that we can play in portable mp3 players, burn to audio cd, and get for free. And you want us to pay for something (probably more $ than a normal cd) that we can't listen to on portable players, or our PC's (without hunting up a disc)? Where's the advantage here??

Ok, this is just stupid. If you want more people to buy CDs, drop the price. Copy protection is a waste of time and will irritate people.

Here's an indepth article on SafeAudio, how it works, and how you can bypass it.

1.) Plug CD player audio out into computer line in jack.
2.) Record sound and save on computer.
3.) Encode and upload

So you replace the usual "Rip CD" with steps 1 and 2, big whoop. I think it's next to impossible to create a cd that will both allow you to listen to it AND be impossible to copy. Anything you can hear, you can record.
I also agree with other posters here: it won't be long before a crack is made.

I am not into writing protections for audio cd's, but I believe the point behind most/some/at least one? of these types of protections is to do the following:

1. Put some form of errors on the cd which take advantage of the differences between reading the data and playing the data (i.e. audio and data cd's). These errors should be such that it is either not possible to get the data off the cd digitally or to get it at a lower level of quality.
2. Put some errors, high/low frequency noise? into the music itself such that when played back (and hence converted by a D/A) the errors/noise cannot be easily detected (or at all), but enough so that if the resulting analogue signal is passed through a A/D the result is of a lower level of quality. (i.e. your example of plugging in a cd player into the line in jack of your audio card).

So the relative effect of the resulting protection depends on those two points (and probably many others that I do not know about). The mind set is, if some of the people cannot copy the music, and if the majority of people aren't happy with the quality of the 'rip', they will go out any buy the original cd.

The problem with this is that many people (myself included) are against the idea of buying a cd which has errors on it. It is like buying damaged goods. And these errors HAVE to be noticable at least to some extent because if they're not they wil not be able to degrade the quality of the 'rip' far enough to deter people from copying the cd's.

I am reading the Peer-to-Peer book put out by O'Reilly and there are a couple of appropriate quotes:

"In the analog world, it costs money to make a copy of something. In the digital world, it costs money to prevent copies from being made."

"The main [Digital Rights Management] effort is...to bring the inconvenience of the physical world to the internet."

Clay Shirky was the author.

They can do what they want. But (Macrovision's) Safeaudio is already cracked. And SunComm's technologie will follow soon I guess.

I dont see how this can ever work. I dont see how it will be possible to make a cd that is secure yet compatible with all standard cd audio players. copy protection in vcrs was easy with closed box hardware that no one could easily mess with. You would think RIAA etc would have learnt from the dvd encryption drama that protecting something on computers is pretty much impossible. especially this!

yet again they are going off on the "it will enhance user experience" crap again. grrr lies lies lies.
