So this uses exif data, which as people here have noted can be stripped, but can't you still ID digital cameras from things like sensor noise? I haven't looked at the statistical properties of it, it probably changes over time, only works on at high ISOs, and search would be way more intensive, but I know that my camera has a very predictable noise pattern.
