DVD Security Group Says It Has Fixed AACS Flaws
SkillZ wrote to mention an article at the IBT site discussing a fix to the security breech of the HD DVD and Blu-ray media formats. "Makers of software for playing the discs on computers will offer patches containing new keys and closing the hole that allowed observant hackers to discover ways to strip high-def DVDs of their protection. On Monday, the group that developed the Advanced Access Content System said it had worked with device makers to deactivate those keys and refresh them with a new set."

Do they not understand, that if you can view it, you can copy it?
On the other hand, maybe they do understand, and HD-DVD/Blu-Ray 2.0 will offer only un-viewable content. Step 3, profit!

and it will join the ranks of every other DRM mechanism devised.
"Corel has told users of its software that failure to download the free patch will disable the ability to play high-def DVDs."
Is this making a reference to the current crop of HD's that were purchased? Does the software phone home? Just curious. Any thoughts?
How about future successes ?
If that's "fixing the flaws", then I guess whenever I fill my gas tank I'm "inventing perpetual motion".
The flaws aren't fixed. They're just papered over slightly more aggressively. Don't worry, there'll be more flaws.

I read this bit:
"New high-def DVDs will include updated keys and instructions for older versions of the PC-playback software not to play discs until the software patch has been installed."
No one gives my computer instructions but me. So I will have nothing to do with either of these formats at all. I am just gonna say no and take my business elsewhere.
DVD is quite fine, and where it doesn't then there are hard drives. Hollywood can give me movies in a format I'll accept or they can e2fsck off.

I am just wondering what "normal" customer's will think, I mean - geeks and technophiles understand the the new efforts to close AACS is just not a solution, just another workaround in a loosing battle. But I wonder what normal people think, I really doubt that average Joe will think that a patch to this system is really a good thing. Most people want to be able to copy their content, make backups, etc. One of the benefits for a lot of people with the DVD format is that DVD players are available as region free players, you can copy disks from friends, etc. I'm not saying that piracy is necessarily a good thing, just that far too many (and increasing) people enjoy that and that in itself will be a problem for the next-gen media players.
No no no. Let's just tidy that baby up a bit:
"Makers of software for playing the discs on computers are requiring consumers to download patches that will re-apply the product defects that computing professionals had removed in the weeks prior. Despite the fact that nothing is technically wrong with the older versions of the software, it is being intentionally rendered obsolete to force the update -- no new movies will be viewable on the old software."

They didn't fix any flaws. They just deactivated old keys and issued new ones. Supposedly InterVideo will be patched to be more secure (aka try to hide the new key). Maybe that is what they are talking about but it still does not fix any flaws by a long shot. Just look at all the cracked versions of software out there that have all kinds of fancy safety and protection mechanisms and are still cracked daily. As long as its in memory in unencrypted form for any amount of time, it can be obtained.
What they have done is analogous to re-keying a lock that is susceptible to being picked -- it's only a matter of time before it is picked again. Lather, rinse, repeat. And how long before a hardware player is cracked? If I had one I'd bust into it to see what kind of flash it has. It probably has an on-board JTAG or other programming port to dump the memory like most consumer devices which are mass produced and then flashed assembly style, making obtaining the key quite easy. When the players come down in price I fully expect them to be cracked on a daily basis.

I guess that nobody with VC understands that DRM is simply a VERY expensive, very stressful game of whack-a-mole.
It amazes me that so many people believe that they can do the DRM game and make huge money. Recent news tells me that if the US government is trying to influence other countries to do more about copyright infringement, well then, DRM must not work worth a damn, otherwise there would be no need for US Governmental intervention. With that bit of proof that it won't work, doesn't work, and can't work, it should be relatively obvious to all concerned that the only way that DRM *CAN* work is if governments create laws that make it illegal to not use DRM.
Media and content providers simply have to get on the right bandwagon... DRM isn't it. No matter what fantastically great work they do for any particular DRM scheme it will always end up broken. There is no method that can reasonably ensure secure keys when the unencrypted content has to be present to view it. Sigh, old dogs, new tricks, bad circus experiences....

Well, that teaches me for not using preview. Here's the non-HTML-formatted version (with real paragraphs!):
--
I know I'm getting offtopic here, but I personally know some people who are rich, own copyrighted content, and are absolutely obsessed with controlling it. They're not people I can understand. They think that every reasonable fair use right should be carefully meted out by themselves alone, that they should be able to revoke rights to anyone at any time for any reason, that allowing a user to copy their content without explicit licensing and permission would be the start of some file-sharing apocalypse. It's not even so much about the money with them as it is the power and control.
And every time they hear about DRM being broken they want some new, better way of controlling their media.
As much as I praise EMI for their actions of late, I can't help but think the people I know represent the bulk of the **AAs. The more we prove DRM is useless to a customer that has access to the hardware and software, the more appealing "Trusted Computing" will become to the Industry. Add a nanny-state government to that and you've got a recipe for disaster.
And the "average consumer" wouldn't raise a stink about it. Even a locked-down home-phoning appliance could run Microsoft Office and QuickBooks and HALO*, so 99% of people wouldn't care. Tell them it's more "secure" and they'll buy it.
(...wait, they already play HALO on locked-down home-phoning trusted-computing appliances...)
How can I believe you when you tell me what I don't want to hear?

You're missing the point.
The benefit of all these cracks isn't to allow people to copy the movies. That ability was never in doubt -- people will always be able to do that. They'll be able to do that regardless of what the content monopolies do, short of just deciding that they won't release movies anymore (which is fine; there's enough of a demand for entertainment that other people will do it -- there's nothing special about making movies that a lot of people can't do, it just takes a lot of money).
Holding onto a crack until AACS is ubiquitous wouldn't do anything. The ultimate failure of AACS isn't, and never was, in doubt -- all DRM is flawed, and it will eventually be broken.
The question is whether it's possible to convince both the studios/content-creators, and consumers, of the utter futility of DRM in the first place, so they'll stop trying to do it, and stop wasting everyone's time. DRM is nothing but a broken window: it's millions of man-hours and probably billions of dollars of resources diverted from other, more productive, tasks, both to create it and break it. That's the real cost of DRM.
So if by releasing cracks for AACS every time they update it, as quickly as possible, it demonstrates to the studios that they're engaging in a war against a guerrilla enemy that they can't possibly defeat, regardless of how much money they spend, perhaps they'll throw in the towel sooner rather than later. It may be a slim chance, but given that Apple has started to see the light, there's some hope.
That's the real benefit of these cracks. Compared to the economic and social cost of the wasted effort, the ability of people to pirate a few movies pales in comparison.

I'm sorry, but this is /. and we only allow automotive analogies here. Please rephrase.
It must have been something you assimilated. . . .
Audio CDs were invented in 1983, before many people were computer proficient to make perfect digitial copies of songs. It was only in 1991 or so that digital DRM was invented.
True Audio CDs have no DRM. New "CDs" that have no DVDs hidden on them should have no DRM, since no one is making pure "CD" DRM anymore. If you buy CDs from non-RIAA labels, you should never run into DRM at all.
Now, DVDs do have DRM. So the question is, how do we get manufacturers to make Laserdiscs again?

Here is the important question:
;)
If you were the implementer of AACS on HD player SW, how would you hide the key? I can think of a few ways:
1. Keep the data in CPU registers and cache.
2. Split the keys up into smaller pieces, and spread them around when in memory.
It seems that both is basically security through obscurity, and that has not worked very well in the future.
If you respond to this with a clever way to do this, make sure you post the reason it will not stand up to hackers as well. Otherwise, keep it to yourself

Someone just has to write a ps3 cell code to do the key guessing just like folding@home, 100,000 pirates, and whammo, it would be cracked really fast , maybe 24hrs. Ironically, that the device player to
make bluray popular could be used to actually crack the keys the fastest.
