LGS‐Net: A lightweight convolutional neural network based on global feature capture for spatial image steganalysis

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.

Micro protocol engineering for unstructured carriers: On the embedding of steganographic control protocols into audio transmissions

, 2015
Network steganography conceals the transfer of sensitive information within unobtrusive data in computer networks. So-called micro protocols are communication protocols placed within the payload of a network steganographic transfer.

An Improved Near‐Reversible Technique With Residual Networks

IET Image Processing, Volume 19, Issue 1, January/December 2025.
The study compares three cover‐image extraction subnetworks with varying residual depths, combining convolutional neural networks (CNNs) and Residual Networks (ResNets) to improve cover‐image reconstruction quality, ensuring high‐fidelity, nearly reversible reconstruction.

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.

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 ...

Integer wavelet transform‐based secret image sharing using rook polynomial and hamming code with authentication

CAAI Transactions on Intelligence Technology, Volume 9, Issue 6, Page 1435-1450, December 2024.
Abstract As an effective way to securely transfer secret images, secret image sharing (SIS) has been a noteworthy area of research. Basically in a SIS scheme, a secret image is shared via shadows and could be reconstructed by having the required number of them.
