I know, that it would require a _lot_ of processing power most likely,
but consider this from freshmeat:

  libsift 1.1

About: The scale-invariant feature transform is an algorithm to identify
and locate interesting points within an image. For all such points, a
descriptive signature is extracted. The signatures can be stored and
matched among multiple images, allowing for a large number of
interesting applications, such as aligning overlapping images and
identifying objects or motion within image sequences. libsift is used by
the autopano-sift program to create panorama images.


Just as you can "fingerpint" text, you can fingerprint Images. I wonder
if this would be a viable solution. Comments?

(Because I am thinking about doing a proof of concept)
