The security systems at airports are an interesting example of security “theatre”, where much of what goes on is about re-assurance rather than being particularly effective. I’ve blogged before about this and had some interesting responses, especially around the intrusiveness of current processes versus their effectiveness and where vulnerabilities lie. For obvious reasons, I won’t go in to this.

However, the TSA in the United States is rolling out a new version of their full-body scanner, apparently in response to the criticism that the old-versions were a step too far: the TSA initially denied, for example, that pictures of people’s naked bodies could be stored until several incidents emerged of security staff doing exactly that. Apparently this will be available as a software upgrade. The question is, will the UK do the same?

The new scanner overlays identified potential threats from scans over a generic diagram representing the human form and so masking who the subject is. This has to be a good thing, but like I said in my earlier post, a reliance on technology rather than using intelligence-led investigations will always lead to vulnerabilities while inconveniencing that majority of people.

I’d rather the people who would do me harm never made it to the airport.
