Body-scanners in railway stations in the UK?

Victoria Cohen writing in her column in The Observer, UK, on Sunday mentioned that she had read of body-scanners being used at Bath railway station. She used this as the starting point for a standard kind of warning on increasing surveillance.

Now, normally, I would thoroughly approve, and such diffusion of technologies of surveillance would fit with the trajectories we outlined in the Report on the Surveillance Society a few years back. However, it didn’t take a lot of digging (and I am probably not the only person who has discovered this) to find that she was basing her column on a misinterpretation of what had gone on in Bath. According to an Avon and Somerset Constabulary press release, what was happening was a temporary exercise conducted jointly with the British Transport Police, using not a body-scanner but a metal detector (or ‘knife arch’ as they are sometimes termed) and sniffer dogs. This was apparently part of a policy to raise awareness of nightlife safety.

There are of course still many issues with the routine use of both sniffer dogs and metal detectors, but we need to be very careful to get the facts right when we are making comments about the spread of surveillance. Get things wrong, and the whole issue can get tarnished as alarmist.

Body-scanners are not being used in UK railway stations. Not yet, anyway…

Billions wasted on airport ‘security’

A new report from the International Air Transportation Association (IATA) say that the industry is wasting billions on unnecessary and ineffective security procedures which are slowing down travel and damaging the whole sector’s economic prospects, according to The Guardian. This comes only days after the German government decided not to introduce body-scanners after trials showed them to be unreliable.

The argument is not particularly surprising, but there seem to be interesting aspects of the issue (apart from the basic human rights problems which we should never forget). The first is that clearly someone is benefitting economically, even if it is not the air transport sector, and that someone is the security industry – although as it happens, a whole range of people and companies have benefitted from the aftermath of 9/11. The Guardian article mentions that UK-based scanning company, Smiths, has tripled its profits this year to near $1Bn, despite the problems with scanners. However, it isn’t all bad. In European domestic and regional markets, airlines have lost out to railway travel, and this can only be a good thing in terms of environmental concerns.

The second aspect is that IATA is using this to push the revival of integrated ‘trusted traveller’ plans coming out of the USA. Many countries have bilateral schemes, but the idea is for travellers with ‘nothing to hide’ to submit personal information to a central body that would validate them without the need for time-consuming checks on the airport. So far, such schemes have been largely restricted to business-class passengers, raising the strong possibility of confusion between really improved security and simply buying more convenience. However, there is another problem from the point of view of security here too: one of the major concerns for security is so-called ‘clean skins’, terrorist who have never triggered any suspicion because they are either entirely new converts to the cause, or have been deep undercover for years cultivating an unblemished record.

In any case, it appears that the security companies are trying to get past the criticism by producing new seamless and less intrusive scanning technologies that would not require long waits and would be integrated into the architecture of airport corridors etc. Of course, the delays and inconvenience of obvious security and surveillance procedures have a purpose and are not just by-products. There is, theoretically at least, a consciousness-raising effect of what Bruce Schneier calls ‘security theater’. If these new gadgets work, and the German trial suggests that there is often more smoke than heat in claims about effectiveness, this effect would be diminished in favour of speed and convenience for an as yet unknown proportion of travellers and much greater inconvenience for the remainder. It’s an interesting conundrum for the authorities…

Lives at stake for social media users

Al-Jazeera is carrying an excellent piece from the Electronic Frontier Foundation reminding social media network owners and regulators in their home countries that lives could be at stake because of the choices they make about security, privacy and anonymity.

Countries like Syria and Iran are purusing a plethora of surveillance and disruption tactics to identity and frustrate activists using social media to organise against their oppressive regimes, and the responses of the networks could be vital. This is something that Google in particular does not appear to have appreciated at all in its current insistance on ‘real indentities’ being the basis for all networking on Google+. Its attitude makes a very naive and dangerous assumption about the nature of states both present and future.

Guess who likes the UK’s proposals to control the Internet?

In the wake of the riots, several British Conservative MPs, and indeed PM David Cameron himself, have suggested a harsher regime of state control of both messenger services and social networks. Their suggestions have attracted widespread derision from almost everybody who either knows something about the Internet and communications more broadly, or who places any value on freedom of speech, assembly and communication and regards these things as foundational to any democratic society.

However, the a yet vague proposals have gained support from one quarter: China. The Chinese state-controlled media have suggested that the Conservative Party’s undemocratic suggestions prove that the Chinese state was right all along about controlling the Internet and that now these events are causing liberal democracies to support the Chinese model of highly regulated provision (via Boing Boing).

This is pretty much what I have been suggesting is happening for the last 2 or 3 years – see here, here, here and here. It is just that now, the pretense of democratic communication is being dropped by western governments. And just in case David Cameron doesn’t get it – and he really does not appear to right now, no, it is not a good thing that the Chinese government likes your ideas: it makes you look undemocratic and authoritarian.

Blackberry and the London Riots

I’ve been in the papers and on radio and TV a bit in the last few days here in Canada, talking about the London Riots, both as a ‘token Brit’ and a surveillance expert. I’m happy to talk about my feelings as someone from Britain and I’ve made it clear to people that I am neither a technical nor a legal expert, but the conversation inevitably ends up in those domains and others which are really outside my expertise – and I’ve had to be careful what I say.

I’ve generally stuck to three lines:

1. That these riots don’t provide simple moral lessons, they are neither politically-motivated or just about ‘crime’, but they do have roots and implications which are profoundly political – this is about consumerism, class, inequality and exclusion.

2. That you can’t blame Blackberry. That’s like blaming the postal service for hate-mail. The problems for RIM here are twofold: bad public relations from being associated with rioting, and how much it is prepared to sacrifice the privacy of its users to help UK police in an effort to counter the bad PR.

3. That all the UK investment in video surveillance didn’t help stop these riots (see my previous posts).

People like Chris Parsons are the kinds of people that the media need to talk to about the technical issues, and there’s a really fantastic and detailed post from his blog here on Blackberry and security and privacy issues. On legal issues, there’s no-one better than Michael Geist on things like lawful access. His website is here. Michael writes a regular column for the Toronto Star and I was quite amused that when the Star called me yesterday, I had to remind them to talk to him about lawful access issues! The best sociological piece I have seen on the causes is from Zygmunt Bauman.

That said, here’s some links – There’s a podcast here on the Financial Post, which also has a good discussion with Tamir Israel of CPIC.

On the more social side here, syndicated in lots of local and regional papers.

And the usually strangely edited piece in my local paper, the Kingston Whig-Standard, here, also featuring my colleague, Vince Sacco.

London Riots and Video Surveillance, Pt.2

My last post was about the lack of any apparent deterrence of rioting from CCTV. However that’s not to say that video surveillance is proving of no use to the authorities. However the way it is being used says a lot about both the limits of CCTV and the general problem of analysis of video images.

As part of ‘Operation Withern’, the investigation into the rioting, the Metropolitan Police have set up a special section of their website, London Disorder Images, as well as on Flickr, which is essentially crowdsourcing the identification of suspects. Despite being the most well-resourced police force in the UK, the Met lacks the resources, time and expertise to analyse and identify everyone it wishes to identify itself, and with widespread popular anger about the riots, they are banking on opening up the process of surveillance and identification as being more efficient and effective – and they may well be right.

Of course, with the problems of lighting, angle, distances, and image quality, the images vary in identifiability – and bear in mind that the few posted so far are probably amongst the best ones – and no doubt there will be many misidentifications. And, in addition, hundreds of people are already being processed through magistrates courts without much need to video evidence. But it is a tactic we are seeing more and more in many places (e.g. Toronto, following the G20 disturbances).

London Riots and Video Surveillance, pt.1

 A really interesting map on the website of the US monthly, The Atlantic, illustrating the relationship between density of video surveillance cameras (CCTV) and recent incidence of rioting in London. There are many things one can get even from a simple map like this. It’s worth noting in particular that Wandsworth and Harringey are the residential boroughs with the highest concentration of CCTV, and have been hit by rioting. There are also places with both greater and less than average density of CCTV which have not had rioting.
 
Whilst you have to be careful not to mistake correlation for causality, and bearing in mind that this is not a statistically tested verdict, the main tentative conclusion one can draw is that there seems to be no relationship between the presence and density of CCTV and the occurence of rioting. This might seem like  a fairly weak statement, but it is yet more evidence that CCTV has little deterrent effect on crime of this sort (and of course, the rioting is not only explicable as ‘crime’ anyway).

Greg’s Cable Map

Greg's Cable Map

There’s a fascinating interactive map of the world’s undersea communications cables here. It’s also a pretty good guesstimation guide as to where there are, or are likely to be, NSA or subordinate agencies’ (and other non-affiliated intelligence services’) field stations that funnel the data flowing through such cables through computer systems that analyse traffic and content data.
