Digital images contain their maker's mark

By examining the minutia of adjacent pixel values in a photo, they claim
to be able to identify the model-specific demosaicing algorithms. I'm
guessing this can only be done from the in-camera JPEG, since you
wouldn't need to for the raw images. Not sure how useful it actually
is, since it identifies the model, not the individual camera. But it's
technically interesting, anyway, to a geek like me. :-)
