I’m at SOUPS 2013, including the Workshop on Risk Perception in IT Security and Privacy, and will be liveblogging them in followups to this post.
Yesterday I received the NSA award for the Best Scientific Cybersecurity Paper of 2012 for my IEEE Oakland paper “The science of guessing.” I’m honored to have been recognised by the distinguished academic panel assembled by the NSA. I’d like to again thank Henry Watts, Elizabeth Zwicky, and everybody else at Yahoo! who helped me with this research while I interned there, as well as Richard Clayton and Ross Anderson for their support and supervision throughout.
On a personal note, I’d be remiss not to mention my conflicted feelings about winning the award given what we know about the NSA’s widespread collection of private communications and what remains unknown about oversight over the agency’s operations. Like many in the community of cryptographers and security engineers, I’m sad that we haven’t better informed the public about the inherent dangers and questionable utility of mass surveillance. And like many American citizens I’m ashamed we’ve let our politicians sneak the country down this path.
In accepting the award I don’t condone the NSA’s surveillance. Simply put, I don’t think a free society is compatible with an organisation like the NSA in its current form. Yet I’m glad I got the rare opportunity to visit with the NSA and I’m grateful for my hosts’ genuine hospitality. A large group of engineers turned up to hear my presentation, asked sharp questions, understood and cared about the privacy implications of studying password data. It affirmed my feeling that America’s core problems are in Washington and not in Fort Meade. Our focus must remain on winning the public debate around surveillance and developing privacy-enhancing technology. But I hope that this award program, established to increase engagement with academic researchers, can be a small but positive step.
We have a vacancy for a postdoc to work on the psychology of cybercrime and deception for two years from October. It might suit someone with a PhD in psychology or behavioural economics with a specialisation in deception, fraud or online crime; or a PhD in computer science with a strong interest in psychology, usability and security.
Privacy activists have complained for years that the Information Commissioner is useless, and compared him with captured regulators like the FSA and the Financial Ombudsman. However I’ve come across a paper by a well-known anthropologist that gives a different take on the problem.
Alan Fiske did fieldwork among a tribe in northern Nigeria that has different boundaries for which activities are regulated by communal sharing, authority, tit-for-tat or monetary exchange. For example,labour within the village is always communal; you expect your neighbours to help you fix your house, and you later help them fix theirs. (This exasperated colonialists who couldn’t get the locals to work for cash; the locals for their part imagined that Europeans must present their children with an itemised bill for child-rearing when they reached adulthood.) He has since written several papers on how many of the tensions in human society arise on the boundaries of these domains of sharing, authority, tit-for-tat and the market. The boundaries can vary by culture, by generation and by politics; libertarians are happy to buy and sell organs for transplant, where many people prefer communal sharing, while radical socialists object to some routine market transactions. Indeed regulatory preferences may drive political views.
So far so good. Where it gets interesting is his extensive discussion of taboo transactions across a variety of cultures, and the institutions created to mitigate the discomfort that people feel when something affects more than one sphere of regulation: from extreme cases such as selling a child into slavery so you can feed your other children, through bride-price and blood money, to such everyday things as alimony and deconsecrating a cemetery for development. It turns out there’s a hierarchy of spheres, with sharing generally taking precedence over authority and authority over tit-for-tat, and market pricing following along last. This ordering makes “downhill” transactions easier. Alimony works (you once loved me, so pay me money!) but buying love doesn’t.

I was intrigued this morning to see on the front page of the Guardian newspaper a new revelation by NSA whistleblower Edward Snowden: a US eavesdropping technique “DROPMIRE implanted on the Cryptofax at the EU embassy [Washington] D.C.”. I was even more intrigued by an image that accompanied the report (click for higher resolution):
Having done many experiments to eavesdrop on office equipment myself, the noisy image at the bottom third of the picture above looked instantly familiar: it is what you might get from listening with a radio receiver on the compromising emanations of a video signal of a page of text.
