Geotagging and privacy issues
It’s always amazing what you can discover by cross-referencing very simple data.
Using sites like Craigslist, Twitter and YouTube, the researchers were able to cross-reference information contained within publicly available online content to determine the exact home addresses of potential victims, even those who had posted the content anonymously. The experiments didn’t take weeks, days or even hours of research either - the addresses were pinpointed with GPS-level accuracy within minutes.
To demonstrate the ease involved in determining a stranger’s precise location, Friedland and Sommer first “cybercased” Craigslist, a classified ads website often used to post items for sale. Here they found geo-tagged photos which they compared with Google Street View, allowing them to determine the postal addresses belonging to the item’s sellers. Even more helpful (if the researchers were, in fact, thieves), was that several ads included a “best time to call” - implying the hours the sellers were not at home.
In further tests, the researchers cybercased Twitter, which allows mobile users to geo-tag their updates. Third-party applications - like TwitPic, for example, used for posting images to Twitter - also include locational data. Using a Firefox Web browser plugin called Exif Viewer, it was only a matter of right-clicking on an image to reveal location of the Twitter post, plotted on a map.
A third experiment, and perhaps the most devious yet, showed the ease with which this form of cyberstalking could be automated. While the above examples revealed users’ location within minutes, manual effort was still involved. For YouTube, however, the researchers wrote a simple script that automatically recognized when videos were recorded a certain distance away from a primary location, that being the potential victims’ home addresses. When the “vacation distance,” as it was called, was set to 100 KM, the script returned 106 hits revealing who was out-of-town in the test location of Berkeley, CA. After briefly perusing the results, the researchers came across a video from someone who was clearly on a Caribbean vacation and would have made an ideal victim.

Atwood says that this is exactly what startups and designers are doing by relying too heavily on A/B testing. While romantic relationships are certainly different than business relationships, the parallels are interesting. Even though Murray’s character says presumably “all the rights things,” Rita can still tell there is something odd about it. Startups should be wary of testing too many of their decisions and should instead focus on just a few key elements at a time.
