The main objective of image source anonymization is to protect the identity of the
photographer against any attempts to identify the source camera device through PRNU
noise analysis. One way of impeding image source attribution is to suppress the PRNU
noise as much as possible. In this paper, we introduce an improvement on the existing
adaptive photo-response non-uniformity (PRNU) denoising method against source camera
identification. We evaluate the performance of the proposed method with substantial …
