I think they are making direct matches. When they say content I think they
mean if you load a picture of a handbag they don't look for handbags but only
for your specific image of a handbag. So they are searching for a pattern that
looks exactly like your pattern (your image). I assume they are looking at 0 and
1 but there may be other ways to do this.

As the number of images drastically increase on the web each and every
year, I doubt there really is any practical way to catch up. I also
wonder one thing. Just how are they making a match? If they can't
see content, what are they using? Surely its more than file name in that
could be changed easily. If they are checking the ones and zeros, then
they probably are looking at content though there may not have someone looking
at content. They may not know its a face, (unless someone later decided
to open the file) but it I guess would be looking at content.
Now searching for invisible watermarks should be much more effective, but
digimark is still fairly expensive. I hope someone comes up with a
similar service at a much cheaper
price.
