Veriframe verifies documents the same way it verifies video, images, and audio: against the indexed original, never against a guess. Publish a decision, letter, or report once — anyone holding a PDF can check whether the text still matches, and if it doesn’t, the verdict shows the exact words that changed.
The grant is set at € 1,250,000 2,150,000 for the 2026 period.
Why it matters
A modified verdict includes a word-level redline: removed words struck through, added words highlighted. Not "this document differs" — this word, on this page.
Print-to-PDF, different software, different margins: the text is what carries the claim, and identical text verifies as authentic. No false alarms on everyday document handling.
Document verdicts use no machine learning at all. Every comparison is deterministic and reproducible — run it twice, get the same answer — and every claim in the verdict names its evidence.
How VERA works for documents
Your team publishes the original PDF to the Veriframe registry at release time. The registry stores the document’s text, page by page — normalized so that harmless re-exports don’t change it.
A journalist, fact-checker, or citizen drops the PDF they received into the public verify page. No account needed.
The document is matched to its original page by page, then compared word by word. If anything was changed, added, or removed, the verdict includes a redline — the classic strike-through view — showing precisely where the copy diverges from what was published.
What the verdict tells you
Every verdict states its evidence. These are the outcomes the document pipeline distinguishes today:
Printing a PDF to a new PDF, re-saving it with different software, or repaginating it with different margins does not change the text — and the text is what carries the claim. A copy whose text is byte-identical to the original verifies as authentic.
When a copy shares its origin with an indexed original but the text differs, the verdict says which pages changed and shows the exact edit in a word-level redline: the removed words struck through, the added words highlighted.
A page inserted into or removed from a decision is a modification of the document, even when every other page is untouched. The verdict counts and names the affected pages.
Different letters from the same organisation share letterheads, closing formulas, and legal boilerplate — sometimes entire pages. Shared boilerplate is not evidence. A document that cannot be forensically linked to an indexed original comes back not found, no matter how familiar it looks.
Use cases
Index a decision the moment it is published. If a copy with a changed amount, date, or name starts circulating, anyone can see exactly which words were altered.
Before quoting from a PDF that arrived by mail or messenger, check it against the registry. Authentic, modified with a redline, or not found — you know what you are holding before you publish.
A letter that merely looks official is not evidence of anything. When the sender indexes what it publishes, any recipient can check a copy — and a lookalike that cannot be linked comes back "not found".
Honest limits
Verification reads the text layer a PDF was published with. Scans and photos of paper documents have no text layer and are declined with a clear message — not given a guessed verdict.
VERA compares the words of the document. Layout, fonts, signatures, and embedded images are outside the claim — a verdict never asserts more than the evidence it names.
Veriframe is a registry, not a detector. If the original was never indexed, the honest answer is "not found" — never a probability score about authenticity.
Index your decisions and letters at release time, and every copy in circulation can be verified against them.
