Geotags, Interesting read.
 

"When Adam Savage, host of the popular science program ?MythBusters,? posted a picture on Twitter of his automobile parked in front of his house, he let his fans know much more than that he drove a Toyota Land Cruiser."

"Embedded in the image was a geotag, a bit of data providing the longitude and latitude of where the photo was taken. Hence, he revealed exactly where he lived. And since the accompanying text was ?Now it?s off to work,? potential thieves knew he would not be at home."
