First off, THANK YOU for taking the time to give comment... understood it is
not legal or official, but for discussion.
referring specifically to
"What you could do is to use or set up a service that grabs the image
metadata at a particular time to confirm that the image was available
under that license when you or your customer used it."
here is a sample license
at the current time we get whatever information is publicly available on
Flickr, where the image owner released the photo under CC. The license
itself is simply a "screen shot" of the CC 3.0. But this screenshot goes
into the calculation of the "fingerprint" which is an SHA512 hash of all the
info on the page, including a date/time stamp from the NIST Atomic Clock
which we ping at the moment of consummation of the license between the image
owner and the end-user/licensee.
The purpose of this was to protect the licensee (in case the image owner
changes their mind later) by providing an auditable document which not only
the photo, and details of the two parties.
The more difficult "what if" is the case where a "bad actor" steals a photo,
uploads it to Flickr, and sets a CC license to it. But clearly it is their
wrongdoing that could result in a CC photo being improperly licensed by an
end user -- and hence this begs the question whether PictureSandbox.com is
required to "look" at each such photo to verify copyright.
