Daegyu Kim, Chaehun Shin, Jooyoung Choi, Dahuin Jung, Sungroh Yoon

Abstract: Highlights•We propose Diffusion-Stego, a training-free generative steganography framework.•We suggest Message projection, a technique that hides secrets in latent noise.•We achieve high message capacity as well as highly realistic stego images.
