Provenance Lens
Content Provenance for Newsrooms
A newsroom workflow for checking submitted images, recording provenance evidence and documenting what a result does not establish.
Before publication
- Retain the submitted original when possible.
- Run the browser or CLI check and archive the JSON report.
- Record both the evidence and its limits in the editorial decision.
Evidence, not guessing
Provenance Lens reports only what can be checked: a cryptographically signed manifest, a metadata field, a specific codepoint, a documented provider mechanism. When a signal cannot be checked, it says so. It never converts silence into a verdict.
What a report cannot prove
- A valid signature proves who signed a manifest, not that the manifest's claims are true.
- Metadata is trivially editable. Treat generator fields as an indication, never as proof.
- Hidden Unicode characters have many innocent causes, including ordinary copy-paste.
