Online photo albums: If you upload your snapshots to Facebook, Photobucket, Flickr, or Picasa, or other websites or forums, strangers can search through and copy those photos unless you change your settings to private. Same with videos you post to YouTube or Vimeo. And take a close look at any photo you post online; if you've gone through the trouble of keeping your location private, why post photos with landmarks in the background?Smart phones: If you take photos with your smartphone, you may be posting more information than you can see in the picture. GPS-enabled devices can add geolocation information to a photo right as you take it and, when you post that photo online, the metadata (latitude and longitude, time and date) may be posted as well. Check your phone's settings to see if it's enabled or to turn it off.iPhone, BlackBerry, and Android apps: There are several new apps that are supposed to help you navigate social settings, manage your commute, or get information about places that are near where ever you are at a given moment. Grindr, the controversial gay mobile dating app, is debuting a version for heterosexual GPS-powered dating tool that would allow someone to walk into a hotel and see photos and personal information about the other users who are there. Waze.com helps users track traffic conditions using information from other members—which means that another member can track you as well. Be careful about what
you download, and be cognizant of who else may be using it.
