A Downside to Geotagging?
Jan 27, 2009 Live Local
“Geotagging” is a term being used now when photos and things posted online are tagged with their geographical locations.

In an article for this month’s Wired magazine, Mathew Honan writes about his recent experience using GPS tracking and Geotagging. While many people are excited about the availability of Geotagging, especially with the advanced features on the popular Apple iPhone, others are becoming more concerned with the privacy issues this may reveal. Mathew Honan is one of them:
To test whether I was being paranoid, I ran a little experiment. On a sunny Saturday, I spotted a woman in Golden Gate Park taking a photo with a 3G iPhone. Because iPhones embed geodata into photos that users upload to Flickr or Picasa, iPhone shots can be automatically placed on a map. At home I searched the Flickr map, and score—a shot from today. I clicked through to the user’s photostream and determined it was the woman I had seen earlier. After adjusting the settings so that only her shots appeared on the map, I saw a cluster of images in one location. Clicking on them revealed photos of an apartment interior—a bedroom, a kitchen, a filthy living room. Now I know where she lives.
Granted this woman doesn’t have to use a Flickr account, and she doesn’t even need to upload the photos to the Internet, but this does raise some very interesting privacy issues. Are people even aware of the geotagging functions for their accounts? Do they know how to shut them off?
As a website for local communities we tend to look at the amazing possibilities Geotagging will have for localizing the Internet, but the privacy issue is definitely a good concern to have. We hope to eventually incorporate ways of using Geotagging on TownSync, but the most important thing for us will be to allow users control over their own privacy.
