The article argues that modern AI watermarking systems can function as hidden tracking mechanisms rather than simple authenticity marks, and proposes the term “spymark” to emphasize privacy risks. It cites Google SynthID and similar efforts from other companies as examples of signals embedded in images, audio, text, and video that may encode identifiers tied to user data.
