New Harry Potter Book Leaked on BitTorrent

It’s online: digital photographs of every page are available on BitTorrent.

I’ve been fielding press calls on this, mostly from reporters asking me what the publisher could have done differently. Honestly, I don’t think it was possible to keep the book under wraps. There are millions of copies of the book headed to all four corners of the globe. There are simply too many people who must be trusted in order for the security to hold. And all it takes is one untrustworthy person—one truck driver, one bookstore owner, one warehouse worker—to leak the book.

But conversely, I don’t think the publishers should care. Anyone fan-crazed enough to read digital photographs of the pages a few days before the real copy comes out is also someone who is going to buy a real copy. And anyone who will read the digital photographs instead of the real book would have borrowed a copy from a friend. My guess is that the publishers will lose zero sales, and that the pre-release will simply increase the press frenzy.

I’m kind of amazed the book hadn’t leaked sooner.

And, of course, it is inevitable that we’ll get ASCII copies of the book post-publication, for all of you who want to read it on your PDA.

EDITED TO ADD (7/18): I was interviewed for “Future Tense” on this story.

EDITED TO ADD (7/20): This article outlines some of the security measures the publisher took with the manuscript.

EDITED TO ADD (7/25): The camera has a unique serial number embedded in each of the digital photos which might be used to track the author. Just another example of how we leave electronic footprints everywhere we go.

EDITED TO ADD (8/15): Here is a much more comprehensive analysis of who the leaker is:

  • The photographer is Caucasian.
  • The photographer is probably not married (no wedding ring on left hand).
  • The photographer is likely male. In the first few photos, the ring finger appears to be longer than the index finger. This is called the 2D:4D ratio and a lower ratio is symptomatic a high level of testosterone, suggesting a male. However, there is no clear shot of the fingers layed out, so this is not conclusive.
  • Although cameras are usually designed for right-handed use, the photographer uses his left hand to pin down the book. This suggests that the photographer is right handed. (I’ve seen southpaws try to do this sort of thing, and they usually hold the camera in an odd way with their left hand.) However, this too is not conclusive.
  • The photographer’s hand looks young—possibly a teenager or young adult.

U.S. Patent Office Spreads FUD About Music Downloads

It’s simply amazing:

The United States Patent and Trademark Office claims that file-sharing sites could be setting up children for copyright infringement lawsuits and compromising national security.

“A decade ago, the idea that copyright infringement could become a threat to national security would have seemed implausible,” Patent and Trademark Director Jon Dudas said in a report released this week. “Now, it’s a sad reality.”

The report, which the patent office recently forwarded to the U.S. Department of Justice, states that peer-to-peer networks could manipulate sites so children violate copyright laws more frequently than adults. That could make children the target in most copyright lawsuits and, in turn, make those protecting their material appear antagonistic, according to the report.

File-sharing software also could be to blame for government workers who expose sensitive data and jeopardize national security after downloading free music on the job, the report states.

What happened? Did someone in the entertainment industry bribe the PTO to write this?

Report here.

Security Through Begging

From TechDirt:

Last summer, the surprising news came out that Japanese nuclear secrets leaked out, after a contractor was allowed to connect his personal virus-infested computer to the network at a nuclear power plant. The contractor had a file sharing app on his laptop as well, and suddenly nuclear secrets were available to plenty of kids just trying to download the latest hit single. It’s only taken about nine months for the government to come up with its suggestion on how to prevent future leaks of this nature: begging all Japanese citizens not to use file sharing systems—so that the next time this happens, there won’t be anyone on the network to download such documents.

Even if their begging works, it solves the wrong problem. Sad.

The Topology of Covert Conflict

Interesting research paper by Shishir Nagaraja and Ross Anderson. Implications for warfare, terrorism, and peer-to-peer file sharing:

Abstract:

Often an attacker tries to disconnect a network by destroying nodes or edges, while the defender counters using various resilience mechanisms. Examples include a music industry body attempting to close down a peer-to-peer file-sharing network; medics attempting to halt the spread of an infectious disease by selective vaccination; and a police agency trying to decapitate a terrorist organisation. Albert, Jeong and Barabási famously analysed the static case, and showed that vertex-order attacks are effective against scale-free networks. We extend this work to the dynamic case by developing a framework based on evolutionary game theory to explore the interaction of attack and defence strategies. We show, first, that naive defences don’t work against vertex-order attack; second, that defences based on simple redundancy don’t work much better, but that defences based on cliques work well; third, that attacks based on centrality work better against clique defences than vertex-order attacks do; and fourth, that defences based on complex strategies such as delegation plus clique resist centrality attacks better than simple clique defences. Our models thus build a bridge between network analysis and evolutionary game theory, and provide a framework for analysing defence and attack in networks where topology matters. They suggest definitions of efficiency of attack and defence, and may even explain the evolution of insurgent organisations from networks of cells to a more virtual leadership that facilitates operations rather than directing them. Finally, we draw some conclusions and present possible directions for future research.

DHS Enforces Copyright

Why is the Department of Homeland Security involved in copyright issues?

Agents shut down a popular Web site that allegedly had been distributing copyrighted music and movies, including versions of Star Wars Episode III: Revenge of the Sith. Homeland Security agents from several divisions served search warrants on 10 people around the country suspected of being involved with the Elite Torrents site, and took over the group’s main server.

Shouldn’t they be spending their resources on matters of national security instead of worrying about who is downloading the new Star Wars movie? Here’s the DHS’s mission statement, in case anyone is unsure what they’re supposed to be doing.

We will lead the unified national effort to secure America. We will prevent and deter terrorist attacks and protect against and respond to threats and hazards to the nation. We will ensure safe and secure borders, welcome lawful immigrants and visitors, and promote the free-flow of commerce.

I simply don’t believe that running down file sharers counts under “promote the free-flow of commerce.” That’s more along the lines of checking incoming shipping for smuggled nuclear bombs without shutting down our seaports.

Edited to add: Steve Wildstrom of Business Week left this comment, which seems to explain matters:

The DHS involvement turns out to be not the least bit mysterious. DHS is a sprawling agglomeration of agencies and the actual unit involved was Immigration and Customs Enforcement, a/k/a the Customs Service. Its involvement arose because the pirated copy of Star Wars apparently originated outside the U.S. and Customs is routinely involved in the interception and seizure of material entering the U.S. in violation of copyright or trademark laws. In Washington, for example, Customs agents regularly bust street vendors selling T-shirts with unlicensed Disney characters and other trademarked and copyright stuff.

The Secret Service’s role in computer crime enforcement arose from its anti-counterfeiting activities which extended to electronic crimes against financial institutions and cyber-crime in general. But they aren’t very good at it (anyone remember the Steve Jackson Games fiasco?) and the functions would probably best be turned over to another agency.
