No Prompt, No Leaks: A Robust Generative Steganography Framework via Prompt-Free Diffusion
Jingwen Cai, Fen Xiao, Shuhua Deng, Xieping Gao
Generative image steganography synthesizes stego images directly from secret information to achieve inherent security advantages. Latent Diffusion Models (LDMs) have recently emerged as a fundamental image steganography framework that modulates secret latent representations with…
