Lens effects within Sensor Pattern Noise

Back in September of 2018 I had the opportunity to present some of my doctoral work at the 24th Australian and New Zealand Forensic Sciences Symposia. That work has now been published.

ANZFSS24 was held in Perth Australia. Bonus points if you can spot me in the crowd.

In the Australian Journal of Forensic Sciences paper above I outline the signal power breakdown for the main signals contained within images after filtering has been applied to isolate the sensor pattern noise. These noise residues can be used to link image successfully back to candidate cameras. What was demonstrated was that photoresponse non-uniformity noise was the highest powered signal out of the three contenders we examined however, unique lens effects and dark current remained.
