The DRM Scorecard
An anonymous reader writes "InfoWeek blogger Alex Wolfe put together a scorecard which makes the obvious but interesting point that, when you list every major DRM technology implemented to "protect" music and video, they've all been cracked. This includes Apple's FairPlay, Microsoft's Windows Media DRM, the old-style Content Scrambling System (CSS) used on early DVDs and the new AACS for high-definition DVDs. And of course there was the Sony Rootkit disaster of 2005. Can anyone think of a DRM technology which hasn't been cracked, and of course this begs the obvious question: Why doesn't the industry just give up and go DRM-free?"
Just because the ability exists to crack it, doesn't mean that the average Joe on the street can do so.
It discourages casual copying, nothing more, but I can't imagine it was intended to do any more. Nobody's that stupid.

Frivolous lawsuits. Until the RIAA finally realizes that its lawsuit tactic isn't working it's the only attempt at DRM that hasn't been made completely useless yet. Unfortunately I don't see that happening unless/until they lose bigtime in multiple court cases.
The same effect has been observed in software for years, Windows XP had an activation thing built in, anyone who knew what they were doing would bypass it, anyone who didn't (and didn't know anyone who did) would eventually go and buy superfluous copies of software they already owned.
Okay, let's try Alex Wolfe's argument in a different context:
"When you list every major law implemented to "protect" life and property, they've all been broken. Can anyone think of a law which hasn't been broken, and of course this begs the obvious question: Why doesn't society just give up and go law-free?"
DRM doesn't have to be perfect to do its job, anymore than law enforcement has to be "perfect". It just has to be effective enough to keep Joe Average from copying the file. Whether or not DRM is actually "good" or "bad" for media producers is a completely different argument, but Wolfe's sophomoric reasoning does nothing to address it.
There's only one copy protection system I know of that hasn't been (meaningfully) cracked, and that's MediaCipher, created by Motorola for the cable TV crowd. Ironically, it was one of the first ones ever created. (Of course, it helps that the boxes implementing MediaCipher are only rented -- never sold -- to end-users.)
Copy protection next showed up in a major way for computer games, most notably for the Apple ][ computer. This fetish briefly spread into applications software as well as games, until the users thundered, "No Fscking Way." It took about four to six years for this to shake out.
Despite the fact that there is no conclusive evidence that copy protection has any meaningful impact on sales, anti-copying measures are still used extensively, but by no means universally, throughout the games industry. In particular, Unreal Tournament's initial anti-copying measures are little more than perfunctory, and are later dropped entirely.
Near as I can determine, copy protection advocates claim as axiomatic that unsanctioned copying will depress sales to livlihood-threatening levels. They cleave to this axiom with a fervor usually associated with religious fundamentalists. However, every time this axiom is honestly examined, mitigating or even entirely contradictory evidence is discovered. Yet the myth persists.
It's not the technology we need to combat (since Turing proved it can never work). It's the defective thinking.

Unfortunately, the analogy doesn't quite hold. Breaking into bank vaults is more like performing a brute force attack on a DRM scheme, every time you wanted to break it. DRM schemes don't work like that. Typically once a scheme is compromised, it becomes possible for anyone subject to it to break it almost instantly. All it takes is for someone to write a quick tool that automates the cracking process and all the barriers presented by the DRM scheme pretty much fall away.
I'd say that DRM schemes are like having one giant bank vault. Yes, it will eventually get compromised, and once it is, everything inside is trivial to take.
Fundamentally, you're spot on. It is a hell of a lot worse than bank vault security. You can't have the party it's secured against also the one it decrypts for. It just makes no sense! All DRM is crackable by definition, they know this, they just want to make it as much of a hassle as possible.
No, it's flawed because it CAN be cracked easily: The decrypting key is in the firmware contained in your DVD player.
In cryptography, we have an explanation using Alice and Bob. Alice is communicating with Bob, while Eve (eavesdropper) tries to decrypt the message. Alice and Bob have the key to decipher the message, but Eve doesn't. She wants to decrypt the communication *without* the key.
A --- E --- B
Alice in this case, is the Digital Media producer (or encrypter), and B is your DVD. You're Eve. The problem with DRM is that Eve *HAS* the key. By cracking the DVD software (some disassembly, debugging and you're done), Eve can obtain the key from Bob.
A --------- B E
This is the problem with DRM. It's flawed by design. The DMCA is a legal "patch" to this algorithm, punishing Eve if she gets the key from Bob. The problem with DMCA is that the punishment doesn't apply to all countries, and trying to enforce it results in attacking freedom of speech.
It is all about enforcing a monopolistic distribution channel, a walled garden. They are trying to get all of the pie, not just a chunk. I went into more detail here:

Locks are a good way to keep honest people honest, but they should be simple and unobtrusive. The reason why we have key locks on our front doors instead of complicated biometric systems (this may be the wrong audience for this comment) is that they are simple, cheap and less prone to failure.
Remember the front door is public, the lock is public but only the owners have the key. The front door system works because not everyone who can get to the door has the key. DRM simply doesn't work because you have the content, the lock and the key.If this were really happening, what would you think?
