Digital images can now be easily created, altered, and manipulated with no obvious traces
of having been subjected to any of these operations. There are currently no established …

We are undoubtedly living in an age where we are exposed to a remarkable array of visual
imagery. While we may have historically had confidence in the integrity of this imagery …

Cryptology is the practice of hiding digital information by means of various obfuscatory and
steganographic techniques. The application of said techniques facilitates message …

To improve a recently developed mel-cepstrum audio steganalysis method, we present in
this paper a method based on Fourier spectrum statistics and mel-cepstrum coefficients …

In this paper, we present a fully Bayesian approach for generalized Dirichlet mixtures
estimation and selection. The estimation of the parameters is based on the Monte Carlo …

Rendering technology in computer graphics (CG) is now capable of producing highly
photorealistic images, giving rise to the problem of how to identify CG images from natural …

Detection of information-hiding in JPEG images is actively delivered in steganalysis
community due to the fact that JPEG is a widely used compression standard and several …

In this paper, we present a novel stream data mining for audio steganalysis, based on
second order derivative of audio streams. We extract Mel-cepstrum coefficients and Markov …

Source camera identification forensics aims at determining and authenticating the original
sources of digital images to support forensics and get the trace of digital images. This paper …

Feature-based camera model identification plays an important role in the toolbox for image
source identification. It enables the forensic investigator to discover the probable source …
