NASHVILLE, Tenn. (AP) -- Tennessee Attorney General Bob Cooper is warning consumers about the risks of "geotagging."

A news release from his office says GPS applications allow others to use personal information for unwanted marketing "or other nefarious purposes."

The release said a woman's photo on a dating site might give a stalker information about her home or work address.

A home movie of a child's birthday party posted to a video sharing site might reveal location information to child predators.

A man updating his status with a picture might unintentionally reveal that he is not at home.

Potential burglars could be alerted by a family on vacation who use a video sharing site to upload a video taken at the beach.
