Alan Cox Files Patent For DRM

booooh writes "Alan Cox has filed a patent for DRM (Digital Rights Management). From the filing: 'A rights management system monitors and controls use of a computer program to prevent use that is not in compliance with acceptable terms.' According to the patent pledge of Cox's employer Red Hat, they will not license this technology if the patent is granted. And it can probably be applied to the DRM that is in Vista. This forum has a few more details.

Wow!

Either the patent system will be proven rotten, or DRM will be halted! It's a win-win!

"Either the patent system will be proven rotten, or DRM will be halted! It's a win-win!"

Or the patent system will work and the patent won't be granted (prior art).
Or the patent system will work and the patent will be granted because it is narrow in scope (only covers a specific type of DRM) which won't hurt DRM in general because no one implements it in the patented way. (If they do, prior art kills the patent)

Neither.

Read the patent application.

It is actually an interesting take on the licensing paradigm. Most licensing programs either start denying you access which leads to loss of data if this happens in the middle of an operation. Alternatively, they kill your program altogether which is again loss of data. Alternatively they check for licensing only when the program starts. In the days of software suspend and 200+ days of uptimes neither one of these is a good idea.

What redhat is patenting is a three pronged approach - OS suspend, component suspend or application suspend when a license violation is encountered. The first one is obvious, the second one and third one are non-obvious until one consideres RedHat aquisition of Jboss. These actually make a lot of sense in a Jboss application.

Overall, I am not surprised that RedHat has no intention of licensing this commercially. If they provide the relevant support, this will give a Jboss based commercial application considerable advantage over BEA and Websphere.

Hope this works

It might be something that reduces the threat of DRM completely making our computers useless.

Re:How is this supposed to work?

[cgenman]

How, exactly, has prior art been stopping patents from being granted?

Go ahead, license it!

[dcavanaugh]

But with totally obnoxious terms. Red Hat could enact some kind of fee whenever DRM-protected content is played, essentially turning the whole DRM world into pay-per-view. And then there would be the price increases, linked to the average price of cable TV. I even have a name for it: Digital Rights Restriction -- Genuine Annoyance Edition. It that's too long to fit in a banner ad, they could just call it "Revenue Assurance".

The key is not to make money, it is to drive home the high cost of DRM, making the downside totally obvious to all. Remember, no matter how ridiculous the terms might be, it really won't be any worse than the copyright industry will do all by themselves in a few years. But instead of using the salami-slice method, the all-at-once/in-your-face method forces everyone to confront the issue here and now.

I think the DRM patent is a really nifty strategy, and presented here on Martin Luther King day, no less!

Re:It's not likely to affect Vista

[YeeHaW_Jelte]

That's a patent for a DRM-enable operating system.

Seems Alan is trying to patent a subpart of DRM which will render it useless if it cannot be used.

Whatever

[sjbe]

A patent is only useful if you have the money to defend the patent in court. Same with a trademark or copyright. Without lots of cash a patent is an empty threat.

MS & SCO

[UnRDJ]

Even if this is invalid, look how much of a fuss SCO and MS have created with BS IP claims. I'm sure if Mr. Cox has paid attention, he can make a few heads turn. Or at least provide us with some amusement.

Flamebait??

[Cheesey]

Flamebait? "The threat of DRM completely making our computers useless" is not a contraversial statement. Even if you really like DRM, you can probably think of some examples where it has been taken too far: think Sony rootkits, Starforce CDROM damage, and Jon Johansen and Dimitri Skylarov being arrested for hacking their own computers.

Read up on TCPA immediately. Consider how much of the design of Vista has been aimed at preventing access to high-quality copies of information protected by DRM. Should the film industry really have been allowed to design an operating system?

Mr. Cox, you are brilliant

[ratboy666]

The current attack vectors on cryptographic based "DRM" schemes are (1) accidental key leakage, (2) the key exchange system or (3) the fact that the data must be eventually decoded.

Note that (3) is what makes DRM systems very dumb. It also follows that the Operating System must get involved in order to so hide the data.

If the Operating System allows a debugger to run AT THE SAME TIME as the "DRM", its attackable. If the OS allows "unsigned" drivers to run, its attackable.

The OS (for example, Vista) will (eventually) not allow unsigned drivers. It must also "kick out" or "suspend" all non-DRM (unsigned) software when DRM content is played.

This behaviour falls into Mr. Coxs patent.

Now, if (Vista) doesn't implement the scheme, it remains vulnerable. So, the problem must be solved another way.

My suggestion then is to ALSO patent (or disallow) by widely publishing the idea that a hypervisor (VM supervisor) can be used for DRM control as well, and can also be used to suspend, terminate or otherwise control applications that could be used to attack DRM software.

Got that? It's now published.

Re:Making DRM-aware applications even more annoyin

[x2A]

Not if you unconditionally save state before checking DRM, so that it's already saved should it need to suspend.

Microsoft?

[Amazing Quantum Man]

Microsoft? They're not huge DRM supporters by nature

Say what? I have just three words for you.

Go fuck yourself, loser.

Is this honestly the best troll you could come up with ? What is wrong with you people - don't you even try anymore ?

Trolls aren't what they used to be. But then again, I guess being made into a twisted parody of nature enslaved to Morgoth by a second rate hobbyist fantasy author and be forced to remember your time as a relatively benign mythological being from Scandinavian folklore all your miserable existence would do that to you, I guess. And the movie trilogy, which makes mockery of both your original and Tolkien-corrupted nature, would certainly not help.

See ? That's a troll. It combines trivia, imflammatory opinions, and a condescending tone with at least some creativity. That's how it's done. "Go fuck yourself, loser"... Bah.

And moderators: The best comments are always, invariably, drawn out as responses to the worst trolls (sometimes the story itself). Slashdot needs quality trolls. A quality troll is one that hits where it hurts, and provokes people to answer in detail with eloquence and passion. It helps hone your own views to the razor's edge as only a worthy foe can. Without them, Slashdot would be nothing more than a bunch of people congratulating each other over their l33tn3s. "Go fuck yourself, loser" is not a good troll, it doesn't mentally challenge even the dimmest-witted steroid-using old boxer. So mod up good trolls, and mod down garbage like the post I answered to.

Slashdot needs (+1, Troll) besides (-1, Troll).
