Yes, I am screaming: THIS TYPE OF INFORMATION SHOULD NOT BE RELEASED. TOP SECRET! LOOSE LIPS SINK SHIPS! WHOSE SIDE IS OUR GOVERNMENT ON?
I was thinking the same thing... I saw a similar article to this recently that talked about how most digital pictures now have gps coordinates built into them telling where the picture was taken... I didn't think that was information that needed releasing either.
Settle down man...the only difference here is the “container” for the data is different. This has been going on a long time and has been documented before when they were embedding info in png’s and jpg’s.
