How is the confidence score calculated?

It combines weighted signals — document structure, expected fields, embedded ID format, verification codes and image integrity — into a single score out of 100.

Does a high score mean the certificate is genuine?

No. A high score means the document shows no obvious red flags, but only the issuing authority can confirm a certificate is genuine.

What should I do with a low score?

Treat the document with caution and verify it directly with the issuer before relying on it. A low score means several checks did not pass.

Preliminary check — not official verification

This tool provides a preliminary, automated indication only. It is notan official government verification and should not be treated as legal proof of a document's authenticity. Always confirm important documents through the relevant issuing authority.

About the certificate authenticity checker

The certificate authenticity checker combines several independent signals into a single, easy-to-read confidence score. It looks at the document's structure, whether expected fields such as a holder name, certificate number and issue date are present, whether any embedded identifier is well-formed, and whether there are signs of image manipulation. Each signal contributes a weighted amount to the overall score, so no single factor decides the outcome on its own.

The signals we combine

Document structure — does the layout resemble a genuine certificate?
Expected fields — are the key details present and readable?
Embedded ID format — does any identifier pass a basic format check?
Verification code — is there a QR code or reference you can confirm with the issuer?
Image integrity — are there signs of editing or manipulation?

What the score means

A high score means the document is internally consistent and shows no obvious red flags — it is a reason for cautious confidence, not a guarantee. A medium score suggests some signals are missing or weak and the document warrants a closer look. A low score means several checks failed and you should be sceptical. In every case the score is a preliminary triage aid designed to tell you where to focus, and it is never a substitute for confirming a certificate directly with the body that issued it.

When to escalate

For any decision that carries real weight — hiring, admissions, licensing or payments — treat this tool as the first step only. If the certificate includes a QR code or verification URL, use it. Otherwise, contact the issuing authority through a channel you find independently and ask them to confirm the record. That is the step that turns a preliminary score into genuine verification.
