Re: Hacking Pictures?

["Hendrik.Lemelson" <lemelson () pi4 informatik uni-mannheim de>]

Dear Steven,

this can be done by examining the so-called exif-headers of an image. In 
these headers, a lot of information about the image can be stored. 
Examples are resolution, exposure time, camera model, ... If the 
cellphone has GPS built-in and enabled, it can store information about 
the location a picture was taken in the exif header of the image. 
Generally, this function can be disabled in the camera-app of the phone.
I hope I could help you.

Best Regards,
Hendrik
