RIS-MoE: robust and secure image steganography via latent-space optimization with mixture-of-experts denoising

Diffusion-based generative image steganography enables covert communication by synthesizing stego images without relying on cover images. However, existing latent-space methods still struggle to balance robustness, steganographic security, and visual fidelity, especially under practical channel distortions such as comp...
