JPEG Steganalysis Based on Steganographic Feature Enhancement and Graph Attention Learning

no code implementations5 Feb 2023 Qiyun Liu, Zhiguang Yang, Hanzhou Wu

However, in order to detect whether secret information is hidden within JEPG images, the majority of existing algorithms are designed in conjunction with the popular computer vision related networks, without considering the key characteristics appeared in image steganalysis.

Graph Representation Learning for Spatial Image Steganalysis

no code implementations3 Oct 2021 Qiyun Liu, Hanzhou Wu

In this paper, we introduce a graph representation learning architecture for spatial image steganalysis, which is motivated by the assumption that steganographic modifications unavoidably distort the statistical characteristics of the hidden graph features derived from cover images.
