Researchers have developed DeepFreqMark, a novel end-to-end learnable framework for embedding watermarks into AI-generated images produced by Latent Diffusion Models (LDMs). This method replaces traditional handcrafted patterns with a neural message encoder and decoder, offering greater flexibility and capacity. To address training challenges with Denoising Diffusion Implicit Model inversion, the team introduced a Spherical Linear Interpolation (Slerp)-based attack simulation that operates directly on the latent noise. Experiments show DeepFreqMark significantly outperforms existing methods in terms of Bit Error Rate under real-world attacks and can embed up to 256 bits of message capacity. AI
