Targeted Pooled Latent-Space Steganalysis Applied to Generative Steganography, with a Fix
Etienne Levecque, Aurélien Noirault, Tomáš Pevn{ý} +3
Steganographic schemes dedicated to generated images modify the seed vector in the latent space to embed a message. Whereas most steganalysis methods attempt to detect the embeddin…
Dual JPEG Compatibility: a Reliable and Explainable Tool for Image Forensics
Etienne Levecque, Jan Butora, Patrick Bas
Given a JPEG pipeline (compression or decompression), this paper demonstrates how to find the antecedent of an 8x8 block. If it exists, the block is considered compatible with the…
Finding Incompatible Blocks for Reliable JPEG Steganalysis
Etienne Levecque, Jan Butora, Patrick Bas
This article presents a refined notion of incompatible JPEG images for a quality factor of 100. It can be used to detect the presence of steganographic schemes embedding in DCT coe…
Compatibility and Timing Attacks for JPEG Steganalysis
Etienne Levecque, Patrick Bas, Jan Butora
This paper introduces a novel compatibility attack to detect a steganographic message embedded in the DCT domain of a JPEG image at high-quality factors (close to 100). Because the…
