LVMark: Robust Watermark for Latent Video Diffusion Models

LVMark is a watermarking technique that hides invisible digital markers in video diffusion models (AI systems that generate realistic videos from text descriptions) to protect against unauthorized use. The method improves on existing approaches by maintaining temporal consistency (keeping the watermark stable across consecutive video frames) and preserving video quality through a specialized decoder that combines frequency analysis with color information. The technique successfully embeds 512-bit capacity watermarks that remain detectable even when videos are distorted or attacked.
