What is Content authenticity?
Content authenticity is the assurance that content is what it claims to be — created by the claimed author, through the claimed process, and unaltered since. In the AI era it has become a verifiable property rather than an assumption.
Before generative AI, authenticity was the default assumption: reading an article meant assuming a person wrote it. Generation at scale broke the assumption, and the response has been a stack of authenticity infrastructure: provenance standards for media, labeling mandates from regulators, and certification for writing.
Authenticity decomposes into separate claims — origin (who made it), process (how), and integrity (has it changed) — and different tools cover different claims. Signed behavioral certificates cover process and integrity for text; identity systems and platform verification cover origin.
Content provenance
Content provenance is the documented history of a piece of content: who created it, how, when, and what changed along the way. It answers authenticity questions with records instead of after-the-fact analysis.
Proof of authorship
Proof of authorship is evidence that a specific party created a work. For writing in the AI era, the strongest proof documents the composition process itself, since finished text no longer carries reliable origin signals.
