AACS Vows to Fight Bloggers

Jonas Wisser writes "The BBC is carrying the story that AACS has promised to take action against those who have posted the AACS crack online. Michael Ayers, chairperson of AACS, noted that the cracked key has now been revoked, and went on to say, 'Some people clearly think it's a First Amendment issue. There is no intent from us to interfere with people's right to discuss copy protection. We respect free speech.' The AACS website tells consumers how they can 'continue to enjoy content protected by AACS' by 'refreshing the encryption keys associated with their HD DVD and Blu-ray software players.'"

    Actually, as I said yesterday, ignore these threats. Go out and blog. Understand that freedom of speech is NOT a government-granted freedom, it is an inherent one that all people of all citizenship must understand. The U.S. Constitution's (Bill of Rights) 1st Amendment does not say "You are free to speak," it says that Congress shall make NO LAW restricting the freedom of speech -- NO law. Discussing encryption mechanisms is free speech, and Congress shall not abridge that. As for patents and trademark and the rest, as long as you do not mimic the mechanism in your own hardware or software, you're fine, Constitutionally. As long as you do not quote verbatim the actual code used to create this mechanism, you're not violating copyright. The DMCA is unconstitional, and regardless of what Congress, the Supreme Court, the President, or any company says, it is non-binding in terms of the moral realization that Congress, and honestly no State organization, can prevent you from freely airing your opinions. You are free to talk, but no one has to listen.

    From yesterday's post I made about "legal recommendations for bloggers," go out and blog. Say what you want to say. There are more of us than there are of them -- not only can they not afford to go after everyone, they can not afford to go after even a small percentage. Let some bloggers get caught, and all it will do is show other people that non-violent actions should not be criminalized or penalized.

    AACS, your days are numbered. Your salaries will end. Your powers will be diminished. It won't be because of competition from another company (that you are likely in bed with, in terms of promoting the abuse of State power), it will be because millions upon millions of people will ignore you, and all you do, in trying to revoke our inherent (and in my opinion, God-given) right to speak freely amongst ourselves.

      But, to be honest, we all know that a truly free society isn't free at all. You have to have some rules for life to continue. This may be one of them.

      I disagree. A free society is one where all citizens are equally free from legal force that gives power to some and takes power away from others, without their express consent (ie, a contract). In a free society, you and I can contract to limit each other -- but the State can not unless we individually tell them that they can. Also, a free society is one where an individual can make any decision they want, as long as they do not directly harm the physical property or body of another individual. Speech can not do physical harm, so speech can not be criminal, no matter how repulsive it is. The effect of the speech could be a physical reaction, but if that physical reaction is performed by a person other than the speech giver, the speech giver has not caused harm.

"Burn the land, boil the sea, but you can't take the sky from me..." We'll find plenty other things to occupy ourselves with. Who cares about AACS and movies and stuff when you can find something else just as, if not more entertaining, for half the price?

      Entertainment has more to do with time preference decisions than just saving "money" doing something that might seem entertaining. Someone who is very busy and who has a high hourly-value to the market may want a quick relief of "getting away from reality" and may be more than happy to pay $150 per person to see an Opera. Someone who is not so busy, and may not command a high hourly-value to the market may be more entertained reading a book, which could take hours or days or weeks. It all boils down to how you (and the market) value yourself.

      Personally, I see nothing wrong with paying $20+ to buy a movie -- if I can use it the way I want to. I prefer to live in a tiny home so that I do not have to pay for extra unused space. This means I have no room for the clutter of physical movies (DVDs, VHS, etc). Instead, I have a great Media Center PC (yes, Microsoft), and I have 1TB of movies and TV shows available to watch based on my mood. This is considered illegal, even though I have paid for all the movies and shows I watched. I also used my own time/labor to put those movies/TV shows on that PC. I've harmed no one physically, so the law is unjust and ridiculous. Provide me with a process to reimburse the authors/distributors/producers of a given content, and also allow me to put that content into a system that works with my life, and I will pay AND continue to be a customer. I don't believe in NOT reimbursing those actively involved in the creation of content. I have no desire to pay for the lawyers, DRM researchers, or those who lobby the State to use force against me to uphold their monopoly.

      Very cute. If the "forbidden number" is fully suppressed, then your post can no longer be decrypted. Hence, suppression of the "forbidden number" does indeed infringe your free speech rights.

      But once the information is in the public realm, it effectively becomes a lost "trade secret".
      Quite right, and moreover, since it is a "lost trade secret", I would argue it has now become "common knowledge." I don't see how any law (DMCA, copyright, etc.) can be used to suppress common knowledge. For instance, Star Wars may be still protected by copyright, but no one can prevent people from quoting it to their heart's content. So many of the quotes have become a part of our culture, our communal consciousness, that they are very much ours, and no amount of government or corporate power can take them from us.

    One part of the article I find funny is this:

    But [Michael Ayers, chair of the AACS business group] accepted that DVDs that had had their copy protection removed were 'now in the clear' and could be copied.

    Isn't that the point? I'm neither trying to justify nor rebuke file sharers, but think about it, man, and be practical for a change. Among those who download and share movies, who really cares about the nitty-gritty details of how keys are cracked, who all gets them, which ones get revoked, what players are and aren't affected, and so on? Most of them only care about one thing: Can I download the HD-DVD of [insert movie titles here]?

    And as long as a key out there is cracked enough for the answer to that question to be "yes," the copy protection industry has lost. They can fight all they want to, but the thing is that unless they literally shut everyone down everywhere, they're doomed. As soon as one single solitary person is able to crack a key and unlock the encrypted data, all of their massive—and expensive—efforts will be in vain.

    I also thought this was funny:

    He said tracking down everyone who had published the keys was a 'resource intensive exercise'. A search on Google shows almost 700,000 pages have published the key. Mr. Ayers said that while he could not reveal the specific steps the group would be taking, it would be using both 'legal and technical' steps to prevent the circumvention of copy protection.

    To Mr. Ayers, I would say this: Get real. For one thing, how many times has it been proven that your technical efforts are futile? How much more time and money are you going to waste developing something that consumers at best don't want and at worst outright resent? For another, what exactly do you plan to legally do to people who live in places where publishing the cracked keys is not illegal? As much as people like you would love to have the U.S.'s misguided laws apply to the whole world, it will never happen, and even if it did, people would still break such laws in civil disobedience.

    If only they could figure out how to fight a winning battle for the hearts and minds of paying customers instead of this inevitable losing battle against people who are much, much smarter than they are, maybe everyone could be happier.

    With other forms of intellectual property, the problem is avoided in various ways: in order to obtain a patent, the description itself becomes public domain. In copyright, the description is bounded by the creative content of that which you create. Trademarks are delimited by "confusion in the marketplace," and trade secrets are delimited by that which is actually kept secret.

    The DMCA purports to create a fifth type of intellectual property, not limited in time, that would bar distribution of information (rather than just physical devices), but has no boundaries on the AACS's theory of what constitutes a "part" of an circumvention device. The boundary becomes "whatever the AACS moves to protect as a part of a circumvention device." But in order to enforce that right, we all have to know what we're not allowed to distribute.

    So maybe the AACS, in order to avoid the paradox, can seek to protect a *range* of values. The scenario just gets even more absurd.

    No. The answer is really that the key, without more, cannot be afforded protection as "part" of a circumvention device. It has to be a accompanied by something more, at the very least a description of how it can be used to circumvent. Otherwise it's just a string of text.

    And that's where the DMCA falls apart, as people with an interest in circumventing can always break apart the information to such a degree to avoid any one part being classified as a "part."

    It's a tough problem, and it should be brought to a court to evaluate. The court in Remierdes had an easy time, because the circumvention device was whole. Fair use will have to be read into the DMCA at some point when it comes to these alleged partial circumvention devices.

  16. The 'unrevocable hack' by Kadin2048 · · Score: 5, Insightful

    (as hackers have created a hack that CAN'T be revoked)

    I spent a while trying to get my head around AACS last night, and the bottom line is that what comes out of the un-revocable hack that you mention isn't the same thing as what's being posted around the internet, and what the AACSLA has the whole revocation scheme for.

    Oversimplification ahead, and I may have some of the details wrong or, but this is the gist of it: the content -- the movie itself -- is encrypted with title keys. These title keys are encrypted with a volume unique key (VUK). The VUK is composed of two parts, a media key and a Volume ID.

    The Media Key is the thing that you get with the code that's being posted all over the Internet (the Processing Key). Processing Keys can be revoked, but only for new discs -- so the discs that are out in circulation as of the compromise of the Processing Key, are out. They're cracked. However, future discs will use a new Processing Key, and that one that's around on the internet won't work ... so the hackers will need to go back and sniff/debug an updated software player to figure out the new Processing Key.

    The "un-revocable hack" you mentioned, doesn't have anything to do with the Media Key, it's all about the Volume ID. The purpose of the Volume ID is to prevent bit-for-bit copying. In a lot of ways it's very similar to parts of the CSS system used on DVDs right now; it's a key specific to each batch of pressed discs, written to the disc in a way that's difficult to read off manually (the drive isn't supposed to let the user see it at all), and impossible to write to a blank disc ... so if you made a "bit-perfect" copy of a disc, the Volume ID wouldn't be there (because you can't read it and/or because you can't write it to the new disc) and you'd be missing one of the elements required to decrypt.

    So: while the Volume ID hack involving the XBox360 drive is a major step forwards (backwards if you're the AACS!), it's not a silver bullet, and it doesn't make future titles trivial to compromise. There's still going to be a cat-and-mouse game in the near future, where the AACS will try to revoke Processing Keys and try to discourage the publication of new ones as discs are released. (It's been pointed out by several people now, that the AACS' over-the-top reaction to publication of the processing key, may indicate that they've realized that their revocation procedures aren't nearly as fast or as flexible as the people who are going to be compromising them.)

    I hope they publish the new keys. I don't want to post some random number and find myself in court because of it.
