In this paper, we attempt to shed light on Benford's law from the viewpoint of probability theory and point out its limitation in image forensic applications. First, we consider a generalized form of Benford's law and relate it to a random variable of a certain probability density function such as the generalized Gaussian or Laplacian function. Then, we examine the application of the generalized Benford's law to image forensic applications and point out such an application is vulnerable to the histogram manipulation attack.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
