How leaving location services on your smartphone can give away your location

The very first statement of this article says it all…

“Location services can give away your location when you take pictures. Pictures may contain EXIF info that includes GPS information.”

This information is known and used by the criminal element out there (such as child sex predators) to reveal the location of kids. I am always preaching to others to avoid posting pictures (i.e. on Facebook) that may reveal more than you desire. Great post by TCAT Shelbyville’s IT Department.

Location services can give away your location when you take pictures.  Pictures may contain EXIF info that includes GPS information.

Don’t want the GPS data on your pictures?  Have Windows?  Right-click on your picture and choose properties.  Next, open the details tab and click remove properties and personal information.   (You can also turn off GPS information on your device – you may want to keep the 911 GPS information on.)

Here is an example of a log file picture with EXIF information from inside of our college.  We of course set this up as an exercise and for training purposes.

We used IrfanView (along with loading its plugins) to find the GPS data.  Irfanview’s Image Information finds the EXIF data and connects to Google Earth and Google Maps.
