Politics &Policy, Volume 53, Issue 3, June 2025.ABSTRACT Deep fakes can be used for political advertising, enabling politicians to change their characteristic features or minimize deficits of their performances. Such a strategy may meet with great interest, which in some circumstances increases participation and might influence deliberation. It was applied in South Korea, and its variations appeared

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.

A Robust Watermarking Method for Hyperspectral Images Based on Hybrid Attention Mechanism
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.Because of the copyright issues of hyperspectral images continue to rise, in this paper, we propose to use a neural network–based watermarking model to protect the copyright. By applying normalization‐based attention module (NAM) to deep dispersed watermarking with synchronization and fusion (DWSF), a NDWSF model is proposed for robust hyperspectral ...
