Dave Farber:
I have a privacy issue question, and perhaps someone on the list can answer it.
I recently wondered if and how programs like Adobe Photoshop embed
information in photographic data to identify creators. 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.
Thanks,
Tim Onosko
