Anonymous Tracking
When online services are accessed via a Web browser, geolocation technology can pinpoint the user's position to within a few meters, employing a combination of the user's IP address, the route taken by packets over the Internet, and any Wi-Fi networks that might be in range of the user's computer. It's even easier if a cell-phone app is used; the app can read the phone's GPS and know, for example, every time the user walks in front of a Starbucks.
So why aren't we already in an age of geospatial advertising, where companies like Facebook and Google send coupons to users' phones as they pass by advertisers' stores? One big problem is the difficulty of serving up such ads without compromising users' privacy.
