I’m very interested in the way in which surveillance and control appear at the intersection of material and virtual worlds, and a topic that has been appearing in marketing articles recently, ‘geofencing’ is causing me some concern. According to Wikipedia (as of 213/11/05), a geo-fence is a virtual perimeter for real-world geographic areas. It seems to be largely connected to mobile commerce and the ongoing desire of marketers to be able to sell to capture customers dynamically, on the move in real-time (see also the piece by myself and Kirstie Ball on ‘Brandscapes of Control’ from earlier this year). There have also been uses of this kind of technology in parole-violation monitoring and child-protection, where alerts can be sent if a device carried by the users strays outside a certain area.

However there is also another aspect of geofencing that works slightly differently: this has been highlighted recently by Russia Today, which reported on discussion at the International Association of Chiefs of Police (IACP) conference into attempts by US police departments, hardware manufacturers and service providers to block users from certain services based on geographical location or particular events. This would essentially make the kinds of actions taken by the Egyptian authorities during the Arab Spring in closing Internet access more dynamic and targeted. So, the example used by RT is protestors trying to organize using Facebook could find that they were unable to access the social media site in particular places etc.

As we use the Internet and Social Media more in more intimate ways to organize all aspects of our lives, the question of not just monitoring but restriction becomes ever more pertinent. If the tracking of objects and people in real-time in order to permit (and speed up) or restrict (or slow down) flows, is one of the key current goals of surveillance, then this interface between virtual and material becomes particularly important and one to which we need to pay a lot more attention.
