Recently, image inpainting has become a common tool for manipulating nature images in a malicious manner, which has led to the rapid advancement of inpainting forensics. Although current forensics methods have shown precise location of inpainting regions and reliable robustness against image post-pr…
Image-within-image technique aims to establish covert communication by concealing a secret image within a cover image. Compared with traditional steganography algorithms, the security of image-within-image technique has not been rigorously evaluated by steganalysis. Existing attack methods just brut…
The steganalysis of JPEG images is a crucial area of research. Deep-learning based steganalysis methods have achieved superior detection performance. All methods for JPEG steganalysis rely on residual networks. Although the incorporation of residual connections has enhanced detection performance, it…
Gaussian mixture model (GMM) is a powerful statistical tool in data modeling, especially for unsupervised learning tasks. Traditional learning methods for GMM such as expectation maximization (EM) require the covariance of the Gaussian components to be non-singular, a condition that is often not sat…
Nowadays a steganography has to face challenges to both feature-based staganalysis and convolutional neural network (CNN) based steganalysis. In this paper, we present a novel steganographic scheme to incorporate synchronizing modification directions and iterative adversarial perturbations to enhanc…
