We're never really alone. Privacy is over. But you already know that, right? The latest? Researchers have been testing out new surveillance techniques and they think you can be tracked around the web using your phone's accelerometer.

According to SFGate security researcher Hristo Bojinov, he discovered that it is possible to distinguish between individual devices by analyzing the data that accelerometers measure provide to webpages.

Bojinov says that it is enough to track a smartphone around the web and all a site needs to do is use a small piece of code that grabs smartphone's accelerometer data.

Bojinov has even implemented that on a Stanford website where you can view your own mobile's accelerometer footprint.

For now, it is unclear whether this is being used by websites and advertisers but Bojinov says he's not surprised if someone wasn't already using this technique.

The research will be formally published in the next month or two. [SFGate via Slashgear via Verge]
