All digital cameras have built-in "yellow dots", because the noise pattern from each individual sensor is like a fingerprint. It's only a matter of time before this becomes a privacy issue.

There's nothing to prevent camera (and cellphone) manufacturers from recording the fingerprint of each device before shipping it, and they could have been doing it for years already.
I wonder to what degree resampling obscures the fingerprint.

But I imagine it would require a decent number of images to analyzed (granted, not a problem in the Harry Potter case). And I'd guess it would be very easy to alter the fingerprint with a few simple GIMP/Photoshop filters.
