Being based in the UK, we are used to being followed by CCTV 24/7, but that does not mean that we have to like it! Therefore, anything that comes along that is aimed at exposing the surveillance is going to be interesting to us. Thanks to the artist Sanser Veenhof there is an app for Google Glass, he has called it Watch Your Privacy! What it does is use available data to locate and warn the user that there is some sort of surveillance in use nearby.
The app uses the OSM Camera database, it will also spot other Google Glass users too so basically you are doing a bit of surveillance too. On the screen, the app will give cameras a number and triangular warning sign. The view will have red non safe zones and green safe zones, so all you will need to do is stay in the green and you will not be seen, how cool is that? Naturally, there will be some unhappy people out there regarding this app, but there always is.
