Does The Number have a lesson for human rights activists?

If you were reading technology blogs yesterday, you probably encountered a string of hexidecimal numbers - 09 F9 11 02 9D 74 E3… - at least once. The string in question is the “processing key” that can be used to unlock the encryption on HD DVD discs protected by the AACS (Advanced Access Content System) digital rights management system. To decrypt a DVD - which you’d need to do to play it on an unsupported platform like Linux, to make a backup of a DVD, or to unlock it and post it to filesharing networks - you need that processing key, the volume ID key (which is easily guessable - it’s sometimes as simple as the movie title and the date is was released) and downloadable software to perform the decryption.

The key has been floating around the web since late last year - Wired’s Gadget Lab blog posted the string on February 13, and included links to software that makes it possible for non-expert users to decrypt DVDs. But most people outside the DVD hacking scene hadn’t encountered the number until this week, when AACS LA, the consortium responsible for the encryption standard began sending cease and desist notices to websites, demanding they stop posting the string. These letters were send under the auspices of the US Digital Millenium Copyright Act, which prevents circulation of “technology, service, device, component” which “is primarily designed or produced for the purpose of circumventing a technological measure that effectively controls access to a work protected under this title”.

The cease and desist letters backfired, in a big way. Searching for the key on Google reveals 320,000 pages that contain the code. (AACS LA has demanded that Google stop indexing sites that contain the string - it’s unclear whether Google will comply.) Many of the user-generated content sites on the web spent yesterday grappling with questions of how to handle posts that contained the number, and the legal ramifications of hosting those posts. My friend Andrew Lih, who is very active in the Wikipedia community and writing a book on Wikipedia, describes events as an all-out cyber-revolt.

Three online communities handled the revolt very differently. Slashdot has a (small) set of articles tagged with the sensitive number, and has allowed articles and comments containing the number to stand. Administrators on the voting-based news site, Digg, started removing posts that contained the number and ended up triggering a user revolt. As Digg founder Kevin Rose explained in a blog post, “We had to make a call, and in our desire to avoid a scenario where Digg would be interrupted or shut down, we decided to comply and remove the stories with the code.”

But the revolt had its intended effect - after brief site downtime, Rose and his admins relented and allowed the stories to survive. In a blog post whose title included the number in question, he noted, “You’d rather see Digg go down fighting than bow down to a bigger company. We hear you, and effective immediately we won’t delete stories or comments containing the code and will deal with whatever the consequences might be.”

Wikipedia, Lih tells us, also dealt with posts, comments, talk threads, categories and usernames containing the number: “As I was hanging out in the administrator’s IRC chat room, there were roughly a dozen or so admins fighting the attempts to add it. They deleted articles, blocked users, blocked IP numbers and ’salted the ground’ so certain articles could not be created. After an hour or so, they had it under control.” Lih notes that Wikipedia is far more accustomed to vandalism and other situations where administrators need to assert control over content than Digg, and so had good systems in place to deal with the outbreak of content that could be legally dangerous to the site.

Reviewing the HD_DVD article on Wikipedia, it’s not clear to me whether Wikipedia has stopped trying to prevent dissemination of the number or not. The article has been locked, and the edits that included the number have been removed from the article history. But the talk thread on the article includes the number as well as extensive discussion about whether Wikipedia is “censoring” the number, leading to criticism from Wired’s Epicenter blog.

In the meantime, the number is turning up in all sorts of online media. As of this morning, Flickr hosted 32 photos featuring the number, including some very artistic renditions, as well as others that reference well-known internet memes. Zazzle.com features a t-shirt imprinted with the number. And it’s just a matter of time before someone mashes up some Jonathan Coulton tracks with someone reading the key…

My interest in the situation has less to do with DVD hacking and more to do with the question of how sensitive information can spread on the Internet. The spread of the number is something of a perfect storm. Many of the techno-libertarians who populate sites like Digg have no great sympathy for digital rights management or the DMCA. The clandestine information - a 16 digit number - is really small, and can be spread through numerous different methods. (As cryptographers have observed, it’s much easier to stop the spread of the video files, which are gigabytes in size, that targeting less that a kilobyte of information…) The people interested in spreading the number have lots of content creation tools at hand. The consequences for spreading the number are percieved to be very low - people posting webpages will likely receive cease and desist notices and most will comply. And the mass nature of the action suggests that most individuals will be spared serious legal consequences, if only because it would be very difficult for AACS LA to bring thousands of lawsuits.

Some of the techniques used to spread the number are familiar to people in the anti-censorship community. Putting the number in an image file is an idea that Chinese anti-censorship activists have been using for some time now. There’s a popular image of Einstein at a blackboard that has been repurposed by activists to spread addresses of proxy servers or messages about the “GFW” - the Great Firewall of China. An online tool allows you to create your own Einstein image with arbitrary text on it. (I suspect it’s just a matter of time until we see Einstein inscribing the hexidecimal code…)

Widespread use of Flickr to spread the URLs of unlocked proxy servers could have an effect in countries like China, UAE and Ethiopia… until governments began blocking FLickr (which they have in many countries that filter the Internet.) To spread clandestine information, it’s important not to have a single point of failure, like a single website that can be blocked. That, in turn, requires that an idea “go viral”, that hundreds of individuals decide to start spreading the information. And that requires an idea that’s sufficiently compelling that individuals agree to take on the risk - however small - of spreading the information.

What would it take to harness this sort of viral spread to harness the net in spreading human rights information? Can activists learn from the story of The Number and find ways to spread information that otherwise is suppressed or ignored in mainstream media?

The only secret that matters is that something's possible.

Sweatshops won't stop because of that we know there are sweatshops in the world. There will always be people who will buy products made in appalling working conditions. They are called the consumers.

Do not buy anything from anyone who is buying from anyone.

I believe what the web allows is the spread of information, in spite of censorship. As the saying from the Arpanet days goes, "The net interprets censorship as damage, and routes around it". The creation of the Internet was designed to allow communications to continue in spite of extensive damage to communication networks. That's why any computer can become part of the net, and there are so many ways of routing information through it. The only true controls are at the choke points as in the gateways into China. Even then, it is not difficult to find ways to route around the censors.

As to human rights, I posted yesterday on my blog about working conditions in China, and had several people resond that they had no idea such things were happening. Creating awareness through a viral meme like a compelling youtube video would not be dfifficult to do at all. It takes getting a good, compelling video out there, possibly with a music track from a major artist, and it would spread quickly.

I copied the "Processing Key" that ends with the number ...56 c5 63 56 88 c0.

I will never use it.

I buy my DVDs. I am old fashioned that way.
But I do object to things like region coding and DRM that prevents me from, for instance, ripping my legally paid for movie to the hard drive of my PC.

Once I own a product. Kindly get out of my life!

So I now posses this stupid "Processing Key" as a way of protesting the overreaching greed and mind numbing stupidity of AACS (Advanced Access Content System) digital rights management system and the idiots behind it.

I think we have to be careful about what kind of lesson The Number can teach activists. I posted something on this here.
