Researchers have developed a novel video watermarking system that utilizes asymmetric cryptography, specifically Ed25519 signatures, to embed watermarks. Unlike traditional symmetric systems where the verifier can also embed, this method allows any party with the public key to verify the watermark without needing the embedding model or network access. The system embeds a 1024-bit signed message into the phase spectrum of the chroma plane, demonstrating high robustness against common attacks like re-encoding and rescaling, and even surviving real-world display and capture loops.
