Verify a sealed report

Upload a PDF to check whether it has been altered since it was sealed. No account, no sign-in, and nothing is kept.

What this checks, and what it does not

When Amavera finalises a report, a digest of the rendered PDF is sent to FreeTSA, an independent timestamp authority with no connection to Amavera. FreeTSA returns a signed record of the time, which is embedded in the document. This page re-checks that record against the file you upload.

It answers one question: does this file still match what was sealed, and was the seal issued by FreeTSA? It cannot tell you anything about whether the inspection itself was accurate or honest. Those limits are repeated with every result below, because they matter as much as the result does.

Your file is sent to Amavera's server, checked in memory, and discarded. It is never written to disk, never stored, and never associated with an account.

Common questions

Does a “not altered” result mean the inspection was accurate?

No. It means the file has not changed since it was sealed. Whether the photographs show the property they claim to, and whether the written observations are sound, are separate questions that no cryptographic check can answer.

The report came to me by email. Is that a problem?

Only if something re-saved it. Forwarding a PDF as an attachment leaves it intact. Opening it in an editor and saving, printing to PDF, or passing it through a converter will produce a file that either carries no seal or no longer matches one. That is not evidence of bad faith, but it does mean the copy you hold can no longer be checked. Ask for the original.

Why should I trust this page?

You should not have to. The seal is issued by FreeTSA, not by Amavera, and it can be checked with any RFC 3161 tool. The technical panel shown with each result publishes the fingerprint of the FreeTSA root certificate this page pins, so you can confirm it against freetsa.org rather than taking our word for it.
