Ed Felton Explains the DRM Designer’s Mindset

Ed Felton has been peering into the mindset of the DRM designer. And what he sees is wheels missing a few cogs:

Freedom to Tinker: A Perfectly Compatible Form of Incompatibility: The whole point of DRM technology is to prevent people from moving music usefully from point A to point B, at least sometimes. To make DRM work, you have to ensure that not just anybody can build a music player — otherwise people will build players that don't obey the DRM restrictions you want to connect to the content. DRM, in other words, strives to create incompatibility between the approved devices and uses, and the unapproved ones. Incompatibility isn't an unfortunate side-effect of deficient DRM systems — it's the goal of DRM.

A perfectly compatible, perfectly transparent DRM system is a logical impossibility.

The idea is so odd that it's worth stopping for a minute to try to understand the mindset that led to it. And here [Leonardo] Chiariglione's [the creator of the MP3 music format and formerly head of the Secure Digital Music Initiative] comments on MP3 are revealing:

[Scientific American interviewer]: Wasn't it clear from the beginning that MP3 would be used to distribute music illegally?

[Chiariglione]: When we approved the standard in 1992 no one thought about piracy. PCs were not powerful enough to decode MP3, and internet connections were few and slow. The scenario that most had in mind was that companies would use MP3 to store music in big, powerful servers and broadcast it. It wasn't until the late ’90s that PCs, the Web and then peer-to-peer created a completely different context. We were probably naïve, but we didn't expect that it would happen so fast.

The attitude of MP3's designers, in other words, was that music technology is the exclusive domain of the music industry. They didn't seem to realize that customers would get their own technology, and that customers would decide for themselves what technology to build and how to use it. The compatible-DRM agenda is predicated on the same logical mistake, of thinking that technology is the province of a small group that can gather in a room somewhere to decide what the future will be like. That attitude is as naive now as it was in the early days of MP3.

Alas, what Ed leaves out is the attitude of the folks who hire DRM designers. They may know perfectly well that other machines can be built to defeat their systems. But they are prepared to make it all illegal (pace DMCA), and use the courts and the cops to spread fear and generally decrease respect for the legal system as it tries to hold back the tide.

Capt. Yee Wins on Appeal

The case of Capt. Yee came to an official end this week when the remaining (minor) charges against him got reversed on appeal.

Convictions Dropped for Muslim Chaplain at Guantánamo Bay: An Army general on Wednesday dismissed the convictions in the case of a Muslim chaplain who was initially suspected of espionage at the Guantánamo Bay prison for terror suspects but was found guilty only on lesser charges of adultery and downloading pornography.

The appellate decision by Gen. James Hill, the Army Southern Command chief who oversees military operations at Guantánamo, wiped the slate clean for Capt. James J. Yee, who ministered for 10 months to foreign terrorism detainees at the United States naval base in Guantánamo Bay, Cuba.

“This means there will be no official mention of it in his military record,” General Hill said.

The decision ended what one of Captain Yee's lawyers, Eugene Fidell, called a “hoax” case.

The case had started to smell pretty bad since shortly after it was filed. Heads should roll over this one. But they won't. Meanwhile Yee's marriage, his career, his life, are all badly hurt, even if there's nothing official in his file.

Sedna Doesn’t Have a Moon

Sedna Mystery Deepens With Hubble Images Of Farthest Planetoid: Sedna's existence was announced on March 15. Its discoverer, Mike Brown of the California Institute of Technology, Pasadena, Calif., was so convinced it had a satellite, that an artist's concept of Sedna released to the media included a hypothetical moon.

Brown's prediction was based on the fact, Sedna appears to have a very slow rotation that could best be explained by the gravitational tug of a companion object. Almost all other solitary bodies in the solar system complete a spin in a matter of hours.

“I'm completely baffled at the absence of a moon,” Brown said.

As you can see from this Hubble telescope photo, there is no sign of Sedna's moon at all. Nope. Can't see a thing.

It Only Hurts When I Don’t Laugh, and I’m Not Laughing

Wonkette is less cynical than me. She can still joke about this stuff:

ROEMER: OK. I'm just confused. You see him on August 6th with the PDB.
TENET: No, I do not, sir. I'm not there.
ROEMER: OK. You're not — when do you see him in August?
TENET: I don't believe I do.
ROEMER: You don't see the president of the United States once in the month of August?
TENET: He's in Texas.

OK, we're starting to get a picture of just how bad the technological lag was at the intelligence agencies… Imagine poor Tenet, desperately wanting to tell the president about this threat to national security: But no! The president is in Texas! Texas! “I just wish I had a way to speak to someone without actually being present in the room… some device that might transmit sound or text over wires… maybe even through the air!

Schneier: National ID is Single Point of Failure for Security

Security Guru Bruce Schneier (who wrote the book that was my intro to serious crypto) argues in an op-ed that A National ID Card Wouldn't Make Us Safer primarily because the GIGO problem for the data we'd use to issue the card makes it near worthless as a security device. What's worse, he says, a national ID card becomes a single point of failure for security if people trust it.

I agree about the GIGO problem (everyone serious does too as far as I can tell). And I agree that the ID cards have about no value as an anti-terrorism tool, although that's where the political push is coming from (their real virtues if they exist, are elsewhere). And I've argued before that over-reliance could be a problem in other ways, but didn't make the single-point-of-failure argument. May have to add that to the list…

Another Cover-Up

New roadside attraction's a cover-up. It seems someone complained about nude classical-style statuary at a garden center because the statutes were visible from the road:

… the statues weigh as much as 500 pounds each and are an ordeal to move. So owners Angie Langford and Pam Gregory came up with a different approach to customer service.

Nearly a dozen concrete statues are sporting crimson velvet two-piece sarongs.

I suppose this explains why people got so worked up about the Janet Jackson thing. No, actually, it doesn't explain it…it's just consistent with it.
