Geotagging - anyone familiar with this? Read an article the other day about this technology and how it's affecting troops overseas, as the GPS coordinates and information can be lodged into a digital picture via the camera without the person knowing it and then when the photos are uploaded to the 'Net, that information can be extracted by people with the knowledge of how to do so.

Also read that it can be used by criminals/unsavory characters (HA!) to find out personal information via the same means and if someone is posting a picture taken in their home, the GPS coordinates can be obtained fairly easily from the uploaded picture due to the embedded data.

Pretty unsettling stuff... anyone familiar with this and if so, know of how to disable or corrupt/encrypt the data so that it can't be extracted from the photos? Any information would be greatly appreciated! Thanks in advance.
