Ad Tracking Commute Graphic (IMAGE)
Caption
This map represents an individual's morning commute. Red dots reflect the places where the UW computer security researchers were able to track that person's movements by serving location-based ads: at home (real location not shown), a coffee shop, bus stop and office. The team found that a target needed to stay in one location for roughly four minutes before an ad was served, which is why no red dots appear along the individual's bus commute (dashed line) or walking route (solid line.)
