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.

A Low Cost Image Steganalysis by Using Domain Adaptation
International Journal of Information Science and Management, 2018 Information hiding and data encryption are used widely to protect data and information from anonymous access. In digital world, hiding and encrypting of the desired data into an image is a smart way to protect information with a low cost.

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 ...

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.

Blind Steganalysis of Mp3stego
J. Inf. Sci. Eng., 2010 In this paper we present a steganalytic attack against mp3stego, a publicly available open-source steganographic tool which uses mp3 audio files as the stego medium to embed hidden information. We first identify through extensive statistical experimentation which parameters of the medium suffer a significant deviation from normality, then we construct ...
