Windows Vista DRM

This article written by security researcher Peter Gutmann (whose previous works include a description of how to securely erase hard drives) dissects the complex web of DRM software that MS has integrated into Vista.

By putting DRM at the absolute heart of the OS, the DRM software can have a wide range of effects, from subtly degrade performance to totally disabling the PC - all the while hiding from system monitoring and debugging software, making troubleshooting potentially impossible.

From the MD who suddenly finds his PC unable to display X-ray images at full resolution, to the multi-national corporation that has its entire IT infrastructure disabled due to an obscure driver bug, to the linux developer who is unable to develop graphics software for the latest cards because MS require that detailed technical specifications for new hardware be kept strictly confidential.

Repost. This is a thread on the top of OS about this already.

Link to this complete BS please (xrays weren't even mentioned in the article you linked), and a statement like this destroys ALL of your credibility.

 
I Retired the true words.

Read the Holy Bible, in the apocalipse.
Without the hands of the Devil no one can make any transaction.
 
Every HD content, like 720P or above, but since we can generate content with Xvid ( A free Codec ) with 1920 X 1080pixels (Formely 1080P), it will not be playable under Windows Vista even If it's completely free, cause if the codec is not aproved By Microsoft , it will not be playable. And if the hardware is not approved, even if you have an appropriate codec, Windows will shows you a quality like the Microsoft software Vista has.
It's not dificult to a user of other systems to gerenate HD content by themselves with 3D software or then by new camcorders HD capable.
Course if you had more money, it will not affect you, but little studios can't make a huge success anymore cause if they do not dance the music Microsoft is playing , will not go any further.

Well, I changed My Mind About Microsoft, first they want to make Retail = Oem for consumer loose more money, loose time with activation. Like they said, the consumer took all charge.

Medical institutions have to avoid Vista to save more lives.
Linux continues with arms wide open.

All lies. HD content is perfectly playable under Vista, it's protected content (e.g. content that has DRM) that will be down sampled. I suggest you research a bit, your making a fool of yourself.

Then Microsoft is wasting their time, a camcorder and a Electric panel can be used to display an DRM Film and record it. With all of the goodies too. So why we have to pay for a new crappy technology ?

DIE , DRM , DIE .


And in the Future, manufactures can say:
And we have those new chips, a new silicon waste, 95% of DRM and 5% of DX12.

Well, they weren't mentioned in the article per se. The article mentions a 'medical IT worker who's using a medical imaging PC'. However, it's not just IT workers who use these PCs, MDs will have to sit at them to view the images. If, as the article suggests, this is potentially a systemic problem then it could affect all users - it is, after all, often the MD who relies on the image to make the diagnosis, rather than the technologist.

As for X-ray images specifically. X-ray and related radiological images are the only types of images for which a robust standard and set of guidelines exist - these guidelines are quite explicit in recommending avoidance of lossy operations/compression and minimum performance of the display device (e.g. a monitor used for mammographic X-ray images should have a minimum resolution of 2560 x 1920 and minimum contrast ratio of 700:1). My point is that evidence based recommendations exist, and equipment that meets these recommendations has been installed at great cost - if an OS can just, haphazardly, degrade image quality without clear warning (as the article suggests) then it could make its deployment very difficult - as if the images are degraded then the PC becomes a paperweight.

As an aside, these recommendations are only strictly followed for X-ray images - and not for photographs and photomicrographs (where the use of JPEG images from a standard DSLR is common practice).

My comment was made to try and rephrase the scenario in the article in language that might be more clearly understood by people outside the field. As someone who works in this field, I can assure you that the context of the scenario is unambiguous.

As to whether, the article is truely accurate in its description of the DRM technology, that's not for me to say. I suspect, and hope, that it is inaccurate, and that the risks have been exaggerated.
 
So many people here in this Forum works on Microsoft. They will defend their jobs...
I defend to Kill DRMs and the entire of the ecossystem of the devil.

Because the example was pure BS, trusted content in the audio path won't degrade a video signal. For the example you gave to be valid the MD would have to be playing a HD dvd on the dispaly WHILE looking at xrays. And in that case it's still the DVD image that will become degraded. Come on now, that is NOT a valid example it's just FUD that people like grelica grab onto and repeat like it's the truth.

I hope you're right. Admittedly, the scenario seemed contrived - however, what happens today, doesn't necessarily reflect what may happen in the future.

One of the advantages of using a general purpose PC, is that you can run multiple sets of software simultaneously - e.g. access a reference text/image library to assist with interpretation of X-rays. Who's to say that future electronic references aren't labelled as 'premium content'? Such materials are likely to be high cost, and the temptation and availability of facilities to make unauthorized duplicates are likely to be high.

Of course, the other thing that's a bit odd is why the whole display should be degraded not just the 'premium content'. This strikes me as being unnecessary, and a strange design choice - assuming that it's accurate (which I hope it isn't).

You'd hope that in a properly managed environment, this wouldn't happen, but unforseen things do happen. It's surely appropriate for administrators to be aware of the issue, if only to recognise the pitfalls should they occur.

It isn't accurate, thats the point. The media is degraded, not the whole display subsystem.
 
So with communications between user-mode and kernel-mode executables being encrypted, I guess that'll mean debugging is practically impossible (unless you put all the debug code in the driver/programs themselves :/).

bsobel, could you provide a link to the thread you're speaking of that contains more discussion?
 
Yeah, it´s FUD, Like Ballmer said , telling for people linux stole IP from Microsoft, well Microsoft Stole entire MAC OS and transform to Windows code, and make it suficient poorer to obligate to encrypt communications between devices to the PC worlds to loose again. If your computer stops in the future, even if you are using a super very stronger system like Linux, and you will not be able to really debug it, cause a inutility was implemented, Microsoft will be blamed by me, yes, they deserve it for the poorer Ideas they implement without user consent or discussion, forcing hardware vendors to sale expensive and inutil hardware like this S**T.
I can Tell you if Microsoft stole entire MAC OS-X, and they did cause they are not really capable of an innovation without causing problems to the consumers, I´d prefer to use the original, not the windows original, but the real MAC OS X. I really prefer real innovators like Steve Jobs or Mark Shuttleworth of UBUNTU LINUX.

VISTA IS A PIRATED COPY OF MAC, WITH HIGH QUANTITY OF POISON. SO WHY DRM THE CORE OF A PIRATED VERSION ?

IF THERE IS VISTA WITHOUT THE DRM BOTTLENECKS, CERTAINLY IT WILL BE 20 TIMES FASTER AND USES 256 MB OF RAM INSTEAD OF A GIG, LIKE THE BETTER SYSTEM CALLED BERYL.

Truth hurts too. So the others do not do the same because they have fear of Microsoft to start to vingate after hear what people are really saying about their systems, but no one tells directly, cause the fear dominates the world of information. I remember one day when I told a friend of mine what Microsoft did to try to stop the use of OpenGL in Vista, he say, no, they will not, until they start to tell about the switch of OpenGL over DX. With more penalties that we cannot use our apps anymore. They proove this to be not FUD, Until users criticism over this approach tell them we are unsatisfied and pretty disgusted.

Tell what you thiink really, I´m preferring to be a real person and tell that I´m pretty disgusted. It´s better than cover on shadow and stay waiting for a more courageous person to do it.

Thanks for the quotes for later too.

Vista tries to stop OpenGL users.
Vista acused RETAIL users of Piracy and tries to Equal OEM = RETAIL.
Vista Tries to force us to swallow DRM without a choice.
Vista specifications causes bottlenecks in the hardware.
Vista remote atestation will force users to stay treatened to " aproved software "

The list continues to expand.

One day Bill Gates tell the most pretty disgusted consumer can be your fisrt alley.
So , do you have courage to tell them what you really think ?
 
Damn, grelica... Did Vista kill your dog or something? You're against DRM. We understand that. Use WinXP. Use Linux. Don't buy Vista.

Except that there's absolutely nothing stopping OpenGL users. nVidia and ATi have yet to properly support it in their Vista compatible drivers. That's understandable, though to their defense, Vista for "home users" hasn't even launched yet. The fact that apparently many in the hardcore computing community either are in computer support or else voluntarily pay upwards of $300/year for numerous MS licenses is irrelevant.

And they dropped that, after people complained. I agree, it would've been great had they not done that in the first place.

Are you suggesting that Mac OSX.whatever that is the first to support BluRay/HD-DVD won't? No. People just won't notice it on OSX, because with the limited hardware pool, all of the macs that come with that version of OSX new will come with a graphics card that supports HDCP and a monitor that supports HDCP.

As for those medical workers watching bluray movies (and note, incidentally, that they don't degrade the entire display, only the movie), they should be fired for not doing their job.

Vista specifications causes bottlenecks in the hardware.
Click to expand...

What bottlenecks are these? Unless you're referring to the fact that matching the minimum specs will make the computer run fairly slowly. Look around for user experiences- after a few days, with the precaching of programs, most users reporting (those without driver problems, anyways) are reporting faster perfromance than with XP on high-end rigs.

Vista remote atestation will force users to stay treatened to " aproved software "
Click to expand...

I think that you meant "attestation," and MS can't check on your "approved software." The only party that can use remote attestation is a company that controls all of its computers. And if I'm an IT Professional, I sure as heck don't want anyone messing with my preconfigured settings and software. And there's currently no evidence of remote attestation being used by anyone else.
