Abstract: 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.
