Bluetooth Geotargetting Project Tracked Thousands of UK Laptops and Mobiles

The City of Bath might be popular with tourists but it is also being used as the test bed for new generation of "big brother" network of what some call, hidden scanners.

Dailymail reported that hundreds of thousands of devices (and their owners) were being tracked using the Bluetooth signals they emit thanks to scanners installed in bars, offices and universities.

The data collected by the tracking devices were then sent to a central database which was created under the Cityware project which for the past three years monitored how Bath pedestrians navigate throughout the city in a bid to help researchers understand the science being group movement which, they hope, will improve public transport.

The data gives the exact location of the owner of the device and can therefore be used to follow their tracks in real time.

Bluetooth devices have unique identifying codes and although many of us rarely, if ever use them, some devices have been picking up details of people's full names, email addresses and phone numbers without the owner's knowledge.

Furthermore, Bluetooth's range, unobtrusiveness and ubiquity makes it easier to be picked by random strangers and scanners alike prompting Simon Davies, from Privacy International, to call the scheme the CCTV equivalent of the mobile industry and the Information Commissioner's Office to look into the scheme.
