How It Works
Watermarking
Adding a detectable signal to AI-generated content so people or software can identify where it came from. A watermark may be visible, like a logo, or hidden in patterns within an image, audio file or text. Hidden watermarks can be damaged by editing, compression or paraphrasing, so they are one part of content transparency rather than proof on their own.
Origin · no single documented coiner
Borrowed from physical paper watermarks and later digital-media security. There is no single documented coiner for the AI usage. NIST includes watermarking among the technical approaches used to identify and track synthetic content.
