Fascinating. I hadn't heard the stuff about each sensor having an individual fingerprint before, but it makes total sense once it's pointed out. Yay, I learned something new today!

I'm a bit dubious. If you are making a jpeg from raw, either automatically in the camera or in software, doesn't all the pixel level stuff get smeared together? And that smearing could depend on the software you are using?
The smearing definitely depends on the sharpening imposed by the development software, but artifacts of the sensor gain pattern would remain. However, this will change over time as the sensor ages, and will complicate things for the forensic software.
