iPod Cracked, But Does it Matter?
According to an Associated Press story, "DVD Jon" Johansen is planning to market a technology for cracking the copy protection on songs purchased from Apple's iTunes Music Store.
This technology will probably be much discussed in the press as the release date draws nearer, but it's a case of using a flame thrower to kill a fly. It's already possible to convert Music Store songs to MP3 without even using any functionality outside of iTunes.
Apple doesn't make this easy to find, of course, and in fact tries to make it look impossible -- if you set your preferred import format to MP3, then right-click on a song in your iTunes "Purchased songs" list and click "Convert selection to MP3", you get the error: "[song name] could not be converted because protected files cannot be converted to other formats". But you can easily burn a series of songs to a CD, then select the songs on the CD and import them into MP3 format. (Of course, if you don't like wasting a writable CD each time you convert your songs, then wait until you've purchased a few more songs and convert them all at once.) All of this is based on core iTunes functionality, which won't go away unless Apple decides to stop letting users (a) burn CDs or (b) import CD songs as MP3 files, neither of which is likely.
But suppose Apple does manage to block this path. (The easiest way I can see would be to write a hidden code on each CD burned from protected songs with iTunes, so that iTunes would refuse to re-import that CD into an unprotected format. Users could re-import the songs with another application, but at least they'd have to open two programs!) You can still use a program like Total Recorder that can capture any sound output on the computer and save it to an MP3 file.
And even if it ever becomes possible for the audio playback application to seize control of the operating system in order to stop programs like Total Control from working, you can always connect a portable MP3 recorder to the audio output of your computer.
It's a common misconception that if a copy-protection algorithm gets broken, it must be because the encryption was too weak or the algorithm was flawed. But the Achilles heel of any such copy-protection scheme is that in order for the content to be playable, the playback program has to "break" the encryption every time, in order to play it. If the content is encrypted using a key, the key has to be stored on the user's computer where the playback program can find it. (If you didn't have to store the key along with the encrypted content, you could use encryption algorithms that are believed to be impossible to break with today's computers, by 15-year-old Norwegians or anybody else.) But even though every copy-protection algorithm is breakable in principle, it's usually easier just to capture the content as it's played back, which is what the previous examples do.
Logically, I think the only algorithm that would help to fight music piracy would be one that embeds a unique "fingerprint" or "watermark" in each downloaded copy of a song -- in the audio itself. A good fingerprint would have these properties:
- it should not be noticeable enough to interfere with the user's enjoyment of the song
- it should not be possible to copy the song in a way that destroys the fingerprint, without degrading the song quality and diminishing its value
In the meantime, don't get taken in by the hype around a new way to "crack" the existed restrictions on copy-protected song files. They were never really protected.
Is anyone really surprised by this?
DRM is such a futile idea that the only way it would be possible would be to lock down consumer electronics so badly as to make them virtually function free.
We call that the theatre or a live performance.

You lose quality if you first convert audio from digital to analog, and then sample it again. But in the age of "CD quality" 128 kBit MP3s and crappy PC speakers, who cares about audio quality anyway...
There is value to a fully digital cracking technique. If you have a large collection of songs, it is a royal pain to set things up to re-record them, re-label them with titles and artists and such... it's good for one or two songs at a time, but for a big collection? Ick. With a digital cracking procedure, you can write an automatic tool that runs at well above standard playback speed and which you can walk away from (or leave running while you browse the Web...)
The World Wide Web is dying. Soon, we shall have only the Internet.
I read most of the article and it discusses breaking drm on music purchased on iTunes. Can someone explain what this has to do with cracking the iPod?
Anyone that assumes that the iPods success comes from iTunes Music Store is mistaken IMO, iTMS helps the iPod alot but what makes the iPod such a hot seller is good marketing by Apple, and a good product. The user interface for the iPod is still the best one on the market (never mind the fact that Apple has a patent on the interface which prevents competition), and iTunes is extremely easy to use even for people that know little about computers. That combined with excellent marketing makes the iPods extremely popular.
Bottom line: there's no reason yet to get excited about the iTunes-cracking technology (and, indeed, no reason to buy an iPod), when you can already convert songs this way
Considering that the iPod is the top selling MP3 player right now it sounds more like he's missing the point than making great insights. He makes it sound like people only buy iPods for the specific purpose of playing music bought from the iTunes store. I'm sure there are plenty of people (myself included) that have never bought music online and bought the iPod for other reasons, be it usability, style, social status or whatever. The ability to play music bought from iTunes never even crossed my mind.
... at least when it is used to identify the original buyer.
Just imagine you have lots of CD/iPods/whatever full of watermarked (with your name) titles. And you lost your stuff or someone stole it. Then those same files are found on P2P networks or on counterfeited CD. And tada, the RIAA lawyer charges you with massive copyright infrigment.
What should you do ? Go to the police to tell them precisely all the tunes you were stolen, then try to fight the RIAA lawyer with that ?
Sorry, but I do not want to take so much juridical risks for stupid songs. The scary thing is that iTunes or any other service could very well implement that in their "burn cd" features, and without telling you about it.
DoubleTwist has the potential to 'decouple' iTunes from the iPod. Want to buy DRM tracks on iTunes then play them on your Sansa? No problem - DoubleTwist will license its software to SanDisk so you can do just that. Want to buy DRM tracks from Walmart that will play on your iPod? No problem - DoubleTwist will license its software to Walmart so it can offer tracks in Apple's DRM for sale.
This could be huge for consumers and a huge blow for Apple. I expect extended court fights!

Dear Slashdot,
I just wanted to say, I've loved reading you for the last few years. I'm sure I clicked on an ad or two to make up for it. I just can't stand the duplicates, unjust bias, and inability for the site to "grow up."
We're just not the same anymore. I don't have time for linux. have a job. I have money to buy a new pc when my old one breaks. I just don't agree with 90% of what you say anymore.
It's been great,

Are you sure this game is new?
Not only did both the submitter and the editor get wrong what the guy was actually planning on marketing, the whole thing was followed by an uninformed and irrelevant rant about watermarking. What's the problem, guys? Are mere dupes getting boring?
You have to give it to Apple. They have a deal with some of the most vicious greedy people in the world to sell their wares. In return they build a DRM that most anybody can get around. With the talented programmers that they have at their disposal they could do much worse. We just need to keep complaining about how horrible it is and enjoy the fact that they have given us the means to control the music we buy. At least we have an alternative to spending $20.00 on a cd that contains one good song.
while stress >= sanity{ coffee++; }
I've heard this argument for as long as there has been iTunes. And it's of course true that there is some non zero degradation.
But is there any objective information on how much worse the sound gets? Does it matter at all in practice? For normal people playing normal music on normal equipment? The few times I've done it, the results have sounded just fine whan casually listening.
A slightly bigger question is if there even is an objective way of measuring sound quality?
DO NOT LET THIS GET OUT! It's super secret.
1. Purchase iTunes album
2. Burn disc
3. import disc
4. what drm?
What you buy via iTunes is an AAC encoded song. AAC (just like MP3, OGG, etc) is a lossy compression format. "Lossy" means that you are throwing away information from the original in order to shrink the size of the song. When you make a CD, iTunes cannot recreate the original full quality song, because it cannot recreate the thrown away pieces. The result is a WAV file of significantly lower quality than the original song. When you then compress the crappy WAV file into an MP3 (and therefore throw away other pieces, different from the ones used in the AAC compression), you get loss of quality which is much worse than the original AAC song.
