The following is a guest post provided by Ben Jackson and Larry Pesce. They are the creators of I Can Stalk U, a website that uses information from geo-tagged photos that have been uploaded to the Internet to expose people’s locations. Their goal is to raise awareness about the potential risks of instantly publishing photos that contain location-aware information.

The combined use of social media, smart phones and location-aware services has recently skyrocketed. A byproduct of this high-tech trio is that people are increasingly posting photos online, because after all, a picture is worth a thousand words – not just 140 characters. However, every digital photo contains data about how it was taken, when it was taken, and sometimes where it was taken.
