Cryptographic or perceptual signals embedded in AI-generated content (image, audio, video, text) that enable downstream detection of synthetic origin.
Definition and scope
Provenance and watermarking sit at the intersection of authenticity verification (proving an artifact's source) and AI-generation disclosure (signalling that content is synthetic). Two technical lineages converge: (a) cryptographic provenance — content-credential standards like C2PA (Coalition for Content Provenance and Authenticity) that sign metadata into media at capture time; (b) statistical / robust watermarking — perturbation patterns embedded in pixels/audio/text that survive recompression, paraphrasing, or screen-capture. Regulatory coverage is the most cross-jurisdictionally aligned of any AI-governance domain. EU AI Act Art. 50(4) requires deepfake disclosure and watermarking for AI-generated content. US EO 14110 §4.5 mandated NIST guidance on content authentication (issued 2024; partly rescinded under EO 14179). China's Deep Synthesis Provisions (Art. 16, 2022) require explicit labelling of synthetic content. G7 Hiroshima §5 calls for interoperable provenance mechanisms. Despite this alignment, NO interoperability standard has been agreed: C2PA, SynthID (Google DeepMind), Stable Signature (Meta), and the various per-vendor watermarks remain mutually incompatible. This is the wiki's most actively contested implementation gap.

Editorial note
When a wiki article references 'watermarking' without scheme qualifier, default to 'robust statistical watermarking' for text+image AI outputs; C2PA-style provenance is a sibling, not a synonym.
