Apple's New MacBooks Have Built-In Copy Protection

raque writes "Appleinsider is reporting that the new MacBooks/MacBookPros have built-in copy protection. Quote: 'Apple's new MacBook lines include a form of digital copy protection that will prevent protected media, such as DRM-infused iTunes movies, from playing back on devices that aren't compliant with the new priority protection measures.' Ars Technica is also reporting on the issue. Is this the deal they had to make to get NBC back? Is this a deal breaker for Apple or will fans just ignore it to get their hands on the pretty new machines? Is this a new opportunity for Linux? And what happened to Jobs not liking DRM?"

Er, it's HDCP.

I don't think you can buy a mid to high end vid card these days that doesn't have HDCP baked in; I'm not surprised.

Note that I didn't say I was enthralled, just not surprised.

DisplayPort

[mpaque]

This is all part of DisplayPort, the display connection. Like HDMI, the digital display connection for HDTV gear, DisplayPort includes an end-to-end encryption mechanism. (Take a look at HDMI/HDCP.)

The end-to-end secure data path is something the HD content providers insist on.

Unauthorized playback protection != copy protect

[penguinstorm]

Playback protection is part of a strategy of copy protection, but it's not the same thing.

Playback protection can hurt me even if I'm *not* trying to copy the media in question, which is my main objection to it.

Copy protection is arguably more legitimate, but it does depend on the specific copyright laws of your jurisdiction.

Up here in Canada the fair use doctrine suggest that it *should* be legal for me to rip a copy of a DVD for my personal playback in another medium (it's roughly the same as making an audio cassette copy of a vinyl record.)

I'm generally of the view that the companies that market media products should focus on improving the quality of those products in order to encourage us to buy them, rather than branding us as criminals. Then again, I still buy music whereas some people seem to not do that at all anymore.

Dear "Mac Fan who wants Blu-ray",

Any major company making a Blu-ray player has 5 options:
1) Do not support playback of copy-protected content. This means most Hollywood stuff won't play, so your Blu-Ray player is useless.
2) Try to hack the copy protection. You may fail; if you succeed then pay big fines and get a court order preventing you shipping products, for violating the DMCA. Go bankrupt. Your employees might go to jail.
3) License Blu-Ray. When playing back Blu-Ray, do not support external screens - restrict it to the laptop's internal display.
4) License Blu-Ray. When playing back Blu-Ray, require HDCP for any external screens.
5) License Blu-Ray, but ignore the license terms. Pay big fines and get a court order preventing you shipping products. Go bankrupt.

Which do you want? You may not like any of the options, but unfortunately there's no other practical option. Apple's choice of (4) is probably the least bad.

These options are due to the requirements of the Blu-Ray spec, and were demanded by Hollywood in exchange for their support. Short of government intervention, Hollywood are unlikely to support any HD format without DRM in the foreseeable future. And Hollywood own the US government (see Disney's perpetual copyright extensions to ensure that Mickey Mouse never ever leaves Copyright), so don't expect any action there.

Now the hardware can actually communicate with other media devices that demand a HDCP connection.

No such devices exist. HDCP is strictly transmitter enforced. All HDCP-enabled display and audio devices are fully capable of doing their job without HDCP being turned on.

However, by enabling HDCP on their video hardware Apple has actually increased the opportunity for compatibility problems. If the Apple video hardware tries to do an HDCP handshake and fails - for any number of reasons, like data corruption or a bug in the implementation on either end, etc - then the end result is likely to be a completely blank screen (it should be obvious that if HDCP is turned on, but isn't working right, the only logical result is for the video hardware to stop transmitting, else it risk transmitting sooper-secret-video in the clear). There have been many reports of just this sort of handshaking failure with all kinds of HDCP-enabled devices like ps3's, blu-ray players, amplifier/receivers, etc.

This is NOTHING like the all-pervasive DRM that infests Visturd(TM) at every turn

I run Vista and I'm not really sure what you are talking about. What extra DRM does Vista have that XP does not? Whatever it is, it is definately not "all-pervasive", or I would have noticed.

Re:To Steve

[mollymoo]

BluRay has provisions for blacklisting players, so if Apple were stupid enough to do that, at some point in the future their users would insert a new BluRay disc which would revoke the keys for their BluRay drive, rendering it useless. I'm guessing Apple don't want that to happen.

Re:Sensational Much?

[Blakey Rat]

Just ignore it, it's a Slashdot myth that Vista has some magical form of DRM that "slows down" everything on your computer. That's as specific as it ever gets. If you ask for evidence of it, they always link to the same one article that refers to MP3 playback on a beta release as "proof."

I've asked about this about a dozen times, and I've never gotten a satisfactory reply. I've also asked for repro instructions for a series of actions that would result in the magical DRM blocking a user action. The simple fact is that the only DRM in Vista is in WMP; the same way the only DRM in OS X is in iTunes. There's no horrible conspiracy, and your computer isn't being "slowed down".

Re:To Steve

[roguetrick]

Cry me a river, you fanboy. It is only insightful because it fits with your broken little worldview. Read the god damn article; it has nothing to do with Blu-Ray and everything to do with the iTunes Store FairPlay Version 3 DRM.

They implemented this crap because if they say no and stick up for their consumers they know they'll get passed by other parties as a content delivery method. They decided to be evil because it grants increased profits. Deal with it.

Looks like I won't be buying a Macbook

[aqui]

For all those slashdoters that work at apple: Make sure you let your Marketing department know that this has cost them a long time customer.

I have a powerbook G4 and I recently bought a mac mini for my wife.

I was planning to get a new Macbook for Xmas.

However hearing about this has changed my mind. I will not let a company dictate what my fair use rights are. I'm disappointed, its so short sighted on Apples part. Technology companies should stick to technology and let our courts and elected members of government worry about our rights and rights of content producers (admittedly they haven't done a good job either).

I moved away from Windows because of this (that and stability issues). I know from the Windows media player 10 or higher behaviour that it won't let me play is my own content (I created it, I own the copyright) and home videos over a projector...

It's bad enough when I have to change software, in this case an open source player (VLC) solved the problem for me. If the "crippleware" is OS and hardware based the only thing at that point is to chose an uncrippled product.

It's too bad. Apple does do a good job with hardware etc.. I've been very satisfied with the Powerbook G4 I have.

I will now be looking at a nice small laptop with an AMD CPU running Linux (probably Ubuntu). If anyone has any suggestions let me know. :)

Thanks.

downloading HD rips off any of the following:

- usenet
- thepiratebay
- isohunt

is a viable, serious option.

of "blacklisting players"

[v1]

The way that works (correct me if I'm wrong here) is that each title has a "title key" (randomly generated exclusively for that release) that is used to encrypt the content.

Sony has created a set of "vendor keys", lets say 1000 of them, to give out to anyone that wants to make a bluray player and agrees to play by their rules.

When a movie is pressed to bluray, the movie's titlekey is encrypted separately 1000 times, once for each vendor key, and is stored on the disc in a title key dictionary. As long as you know at least one vendor key, you can retrieve the title key. Now after apple signs on the dotted DMCA line, they are assigned and given one of the vendor keys. (lets say it's key #256) 256's private key is placed on the bluray player firmware apple ships with. The player uses that key to decrypt copy #256 of the title key from the title key dictionary on the disc. It can't decrypt any of the other 999 copes since it only has private key for #256.

Lets say the firmware is hacked.

Once sony figures out that key #256 is being used by a hacked player, they "revoke" it. This means that every title released after this point will no longer have an entry in the title key dictionary for key # 256. So anyone with an older apple bluray player will not be able to view the new movie because it cannot get the title key from the disc.

Every disc they have that they bought up to the point of revocation will continue to work indefinitely on the older player, because the old discs will all still have a title key in position 256 in their title key dictionary.

At that point if apple wants to get back into the game, the RIAA will force them to strengthen the security in their player firmware to make it more difficult to hack, before they give them a new vendor key. Apple will push this out as a firmware update and once again all their bluray players will work with all titles, old and new.

If it gets hacked again, it's possible sony will just say too bad so sad and refuse to give them another key regardless of what apple is willing to do. At that point all the players with the vulnerable firmware will cease forever to work with new releases.

I know I'm missing several layers of other nasties such as the bluray player vm, but this is the part that's relevant here. Sony can't remotely brick or otherwise damage your bluray player, and cannot prevent it from being able to play discs that it already can play. They can only prevent your player from working on discs released after they decide to drop the hammer.

Re:of "blacklisting players"

[v1]

So what happens if the "hacked" firmware switches Apple's key with, say, the PS3's? Would Sony be stuck?

Part of their agreement to get a key is certain steps must be taken by the vendors when writing their firmware and making their hardware, to make the private key difficult to extract. Any vendor that "loses control" over their key simply requests another one. Sony revokes their old key, causing all new disks to not work with the old firmware. The vendor pushes a firmware update to their players (either by download/usb thumb drive or internet download) to get the new key which is embedded in the new firmware. This is why practically all bluray players have internet connections. It's not a convenience for you so much as it is to make it possible and practical for vendors to recover from getting their key revoked by Sony. No vendor wants their vendor key publicized, but they have to take that into account. If it does get released, and you don't have a way to update all your customers after you get a new key, you've essentially "bricked" all your previously sold units. (at least in the eyes of the consumer, being unable to play new content) And that may be enough RMAs to pull you under.

In your example, if someone managed to extract the PS3's key and embed it in a free bluray ripping software, (unlikely because they "wrote the book" on steps you should take to protect it, but certainly not impossible) they would simply revoke their own key and push a software update to your PS3, required for viewing new movies, like any other vendor.

The only way to beat sony at this game is to reverse engineer or otherwise break the encryption to recover en-masse the entire set of vendor private keys. If that list were to be made public, then Sony would have two options. (1) revoke ALL keys and start from scratch, (requiring all bluray players in the world to receive a firmware update) or (2) give up on it. Right now if a key is compromised, they have hundreds (thousands?) of as yet unassigned vendor keys in the dictionary on every disc being made, so revoking one and handing out another is not a problem because it's already on all the existing discs. But if you have to start over, it makes a bit of a mess because all the old discs only have the old dictionary, and so players would need to have two vendor keys, an old one to play old discs, and a new one to play new discs. I suppose they wouldn't mind that all so much but it may be enough deterrent to make them consider option (2).

That's why the vendors have to sign the agreement and take certain steps to protect their keys. There's a limited number of vendor keys available to be assigned from the start. (anyone happen to know the exact number?) So they can't just go revoking keys every week, they'd run out too soon.

I've read some recent information about "processing keys" being discovered, I don't know if that means someone has found a way to break the entire dictionary. Being able to break the entire dictionary is of course the best thing to see happen. It doesn't bring the whole system crashing down, but drags it down to the effectiveness that is presently on DVDs. (which is essentially non existent now with apps like Mac The Ripper and Handbrake out and about) - meaning open apps can be written to break any disc currently in production.

Ya I guess I am a bit behind the times here. Not sure if I'm getting this right but it appears that the "processing key" is the ONE key that encrypts the content of any bluray disc. The title key isn't actually required to decrypt the content if you know the processing key. Gee that stinks for them I guess. Makes pretty much all of the above a moot point. I'm surprised the bluray ripping apps haven't been popping up like dandelions already. Guess not enough people have bluray drives in their computers yet. Funny how THAT is what's causing this to not hit the fan very fast.

Re:To Steve

What I don't get about the cloud computing thing is this: Folks seems to be missing the big "Oooops" written on the wall. You see,cloud computing can only work when you have bandwidth to burn,which thanks to the lovely telecos who let their networks and backbones fall down while in pursuit of the ever higher profit margin we simply won't have.

So I am making a prediction,and the prediction is this: That 5 years from now any mention of "cloud computing" will be strictly in a past tense. As will most likely Youtube,Netfix on demand,etc. Because the telecos will scream "we have to save the record profits!....errr we mean network,yeah that's it!" and will keep making the caps shittier and shittier until you won't have enough bandwidth to think about such things. Believe me,I know of which I speak. Here in northern AR we have the choice of 20Gb(DSL) or 36Gb(cable) and that's it. You even want to get 100Gb it'll cost you over $300 a month. Which of course the average household can't afford simply to enjoy things like cloud computing,Netflix,etc. Oh,and if you are lucky they'll give you a way to monitor your bandwidth,around here they don't. Helps to make sure folks use less than what they pay for to avoid the $1.50 a Gb they charge if you go over. Enjoy the future!
