Online Privacy Just Got a Lot Less Private

December 15, 2017

Forget for a moment political hacks from other countries and think about yourself. We are far more vulnerable online than you might think. A scary new report was discovered in a University of Washington News story, “For $1,000 Anyone Can Purchase Online Ads to Track Your Location and App Use.”

According to the story:

The researchers discovered that an individual ad purchaser can, under certain circumstances, see when a person visits a predetermined sensitive location — a suspected rendezvous spot for an affair, the office of a company that a venture capitalist might be interested in or a hospital where someone might be receiving treatment — within 10 minutes of that person’s arrival. They were also able to track a person’s movements across the city during a morning commute by serving location-based ads to the target’s phone.

 

Importantly, the target does not have to click on or engage with the ad — the purchaser can see where ads are being served and use that information to track the target through space. In the team’s experiments, they were able to pinpoint a person’s location within about 8 meters.

The scariest part of this story is that, while there are many techniques for hiding your online browsing and consumption, there is not much you can do from being spied on by software like this. However, the ebb and flow of the internet tell us that as soon as this becomes a public concern some programmer with dollar signs in their eyes will invent a solution. We just hope it’s not too late by then.
