The article above describes a system of graffiti surveillance involving police using Global Positioning System (GPS) tagging of photos, etc. We could worry about that, but consider this bigger picture:
GPS is a system that involves a satellite and a ground receiver. The satellite tells the receiver on the ground where the receiver is located, to within a few feet. This system is very handy indeed when, for example, you happen to be lost.
Problem is when your devices report your location without telling you. Your phone might already be GPS-enabled. If not, your next one likely will be. It's not something you can turn off in most cases, because it's used by the emergency services, for example when you dial 911 for an ambulance, in the USA. You have to be tracked for your own good, see?
Your car might already be GPS-enabled. Maybe it has a map or direction finder, very handy. Or maybe it has an antitheft system like OnStar that keeps track of where your car is without telling you. Or maybe your rental car, company car or truck tells the company where you are all the time and your route, again without your knowledge or permission.
Your camera is next, and of course your phone camera. They will have GPS and it will be a "feature." Your photos will automatically contain where and when you took them and with what device, and when you upload to Flickr or whatever, the websites could display that info on a map. Cute, right? Except when the buffers come to the wall hours later or your secret bridge turns into a tourist area, or when the cops need a quick list of every place you hit this year.
GPS is only one of these passive-surveillance technologies of concern. There is also RFID, unencrypted wireless (email, texting, web browsing, pagers, keyboards, cordless phones, most cell phones), surveillance cameras, outdoor listening devices, and cell-phone triangulation, just to hit the high spots.
Clearly, humans need to be more in control of the kind of info their devices are sharing without their permsission. Nothing else will do. Try to buy stuff that has controls that put you in charge and features that are not hidden or automatic. Be aware that your devices can create big security problems for you.
And let's not forget the most dangerous form of self-incrimination: running your mouth. What you say in chatrooms, on phones, on Myspace, in email, to reporters, and to the nice policeman who promised to let you off easy if you just showed him every piece of graffiti you ever painted -- are the most dangerous kinds of self-incrimination available.
