Just curious, and I did a quick google search and didnt really find what I was looking for but here it goes...
Say I have a PDF file, is there a way to insert some sort of tracking into it where I can see where it is sent whether it be through email or what have you and where it goes? Basically an internet GPS tracking device for files?
I doubt its possible but figured I would ask.
Hopefully someone has an idea whether or not it is.
