I’m liveblogging the Workshop on Security and Human Behaviour which is being held here in Cambridge. The participants’ papers are here and the programme is here. For background, see the liveblogs for SHB 2008-13 which are linked here and here. Blog posts summarising the talks at the workshop sessions will appear as followups below, and audio files will be here.
The European Court of Justice decision in the Google case will have implications way beyond search engines. Regular readers of this blog will recall stories of banks hounding innocent people for money following payment disputes, and a favourite trick is to blacklist people with credit reference agencies, even while disputes are still in progress (or even after the bank has actually lost a court case). In the past, the Information Commissioner refused to do anything about this abuse, claiming that it’s the bank which is the data controller, not the credit agency. The court now confirms that this view was quite wrong. I have therefore written to the Information Commissioner inviting him to acknowledge this and to withdraw the guidance issued to the credit reference agencies by his predecessor.
I wonder what other information intermediaries will now have to revise their business models?
We had a crypto festival in London in London in November at which a number of cryptographers and crypto policy folks got together with over 1000 mostly young attendees to talk about what might be done in response to the Snowden revelations.
Here is a video of the session in which I spoke. The first speaker was Annie Machon (at 02.35) talking of her experience of life on the run from MI5, and on what we might do to protect journalists’ sources in the future. I’m at 23.55 talking about what’s changed for governments, corporates, researchers and others. Nick Pickles of Big Brother Watch follows at 45.45 talking on what can be done in terms of practical politics; it turned out that only two of us in the auditorium had met our MPs over the Comms Data Bill. The final speaker, Smari McCarthy, comes on at 56.45, calling for lots more encryption. The audience discussion starts at 1:12:00.
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.
I’m at SARMAC, a conference with a number of research papers on the psychology of lying and lie detection. I’ll liveblog the relevant sessions in followups.
I’m liveblogging the Workshop on Security and Human Behaviour which is being held at USC in Los Angeles. The participants’ papers are here; for background, see the liveblogs for SHB 2008-12 which are linked here and here. Blog posts summarising the talks at the workshop sessions will appear as followups below. (Added: there is another liveblog by Vaibhav Garg.)
In this first of a two or three part instalment. In them Laurent Simon and I comment on our impressions of David Birch’s Tomorrow’s Transactions Forum, which we attended thanks to Dave’s generosity.
NOTE: Although written in first person, what follows results from a combination of Laurent’s and my notes.
This was a two day event for a handful of guests to foster communication and networking. I appreciated the format.
After a brief introduction, the first day kicked off with my ever growing presentation on the origins of the cashless society (you can see it here ).
The following act was Tillman Bruett (UNCDF), who was involved in the drafting of The journey towards cash-lite (at least so say the acknowledgements).

Three Paper Thursday is an experimental new feature in which we highlight research that group members find interesting.
When new technologies become popular, we privacy people are sometimes miffed that nobody asked for our opinions during the design phase. Sometimes this leads us to make sweeping generalisations such as “only use the Cloud for things you don’t care about protecting” or “Facebook is only for people who don’t care about privacy.” We have long accused others of assuming that the real world is incompatible with privacy, but are we guilty of assuming the converse?
On this Three Paper Thursday, I’d like to highlight three short papers that challenge these zero-sum assumptions. Each is eight pages long and none requires a degree in mathematics to understand; I hope you enjoy them.
There’s a huge literature on the properties of static or slowly-changing social networks, such as the pattern of friends on Facebook, but almost nothing on networks that change rapidly. But many networks of real interest are highly dynamic. Think of the patterns of human contact that can spread infectious disease; you might be breathed on by a hundred people a day in meetings, on public transport and even in the street. Yet if we were facing a flu pandemic, how could we measure whether the greatest spreading risk came from high-order static nodes, or from dynamic ones? Should we close the schools, or the Tube?
Today we unveiled a paper which proposes new metrics for centrality in dynamic networks. We wondered how we might measure networks where mobility is of the essence, such as the spread of plague in a medieval society where most people stay in their villages and infection is carried between them by a small number of merchants. We found we can model the effects of mobility on interaction by embedding a dynamic network in a larger time-ordered graph to which we can apply standard graph theory tools. This leads to dynamic definitions of centrality that extend the static definitions in a natural way and yet give us a much better handle on things than aggregate statistics can. I spoke about this work today at a local workshop on social networking, and the paper’s been accepted for Physical Review E. It’s joint work with Hyoungshick Kim.
