Steganalysis of Chat based Steganography
International Journal of Informatics and Applied Mathematics, 2023 Steganalysis is the practice of identifying potential secret communication and taking appropriate action, such as deciphering to uncover the hidden contents or destroying the object containing the hidden information if it cannot be uncovered. At times, it’s very necessary to perform Steganalysis due to the fact that steganography is often ...

Adversarial Attack Based on Perturbation of Contour Region to Evade Steganalysis-Based Detection
IEEE Access, 2021 Deep neural networks (DNN) are applied in various fields because they afford good performance. However, they seem vulnerable to adversarial examples. Therefore, studies are actively investigating adversarial defenses to improve the robustness of DNNs as ...

IET Image Processing, Volume 19, Issue 1, January/December 2025.A new set of filtering kernels are used for the preprocessing layer to facilitate the extraction of image steganographic features. While using depthwise separable convolution in this model, a new residual network block is also designed to better extract hidden information from images.

Tamper Localisation Using Quantum Fourier Transform Signatures for Medical Image Authentication
IET Quantum Communication, Volume 6, Issue 1, January/December 2025.We present a tamper‐localisation framework that embeds authentication signatures as phase‐only perturbations in blockwise QFT coefficients using keyed sparse mid‐band supports and light cross‐block coupling, preserving magnitudes (energy) and imperceptibility.

The secure steganography for hiding images via GAN
EURASIP Journal on Image and Video Processing, 2020 Steganography is one of the important methods in the field of information hiding, which is the technique of hiding secret data within an ordinary file or message in order to avoid the detection of steganalysis models and human eyes. In recent years, many

JPEG Image Steganography With Automatic Embedding Cost Learning
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.A great challenge to steganography has arisen with the wide application of steganalysis methods based on convolutional neural networks (CNNs). To this end, embedding cost learning frameworks based on generative adversarial networks (GANs) has been proposed and achieved success for spatial image steganography.

Leveraging High‐Dimensional Mapping for Effective JPEG Steganalysis
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.Steganography is a critical information‐hiding technique widely used for the covert transmission of secret information on social media. In contrast, steganalysis plays a key role in ensuring information security. Although various effective steganalysis algorithms have been proposed, existing studies typically treat color images as three independent ...

Steganography Defense Network Based on Simulation of Steganography Information Distribution
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.In order to block the spread of illegal stego‐image and reduce the erasing traces of steganography attacks on images, this paper proposes a steganography attack network based on simulation of steganography information distribution. First, a strategy of simulating steganography noise was adopted, and the distribution of steganography noise was learned ...
