We investigate the robustness of
PRNU-based camera identification in cases where the test
images have been passed through common image processing
operations. We address the issue of whether current camera
identification systems remain effective in the presence of a
nontechnical, mildly evasive photographer who makes efforts
at circumvention using only standard and/or freely available
software. We study denoising, recompression, out-of-camera
demosaicing.
