[Ssc-dev] Camera Noise Signature?

[Andrew Senior]

I guess eventually we should think about this problem too, though it is
secondary -needing sophistication, a lot of work and access to many images.
This "instructable" seems like a series of things that should make it
harder, but nothing that is provably de-identifying.
I think there may be more elementary ways of recognizing the make and model
of a camera e.g. the specific compression tables that are used. I've heard
that printers watermark documents to uniquely identify the printer- it could
be that cameras do that too.
