There is non-visual data, so-called "metadata," that is part of JPEG images, for instance. So I decided to open a JPEG with the Notepad program in Windows to poke around.
In doing so, I found several references to "UUID" numbers, and what appear to be long series of numbers that look like serials and/or MAC addresses. So my question is this: Can you trace a JPEG back to someone who created or modified it? If not, what do the UUID numbers in the metadata pertain to? I was under the impression that UUIDs were always associated with Ethernet machine identifiers.
