Upload a PDF you found online or received. We’ll extract the fingerprint and tell you the order it belongs to.

1) Drop your file · 2) We run /detect/guess · 3) Add order_id to run /detect (attribution)

Result

What the fields mean:

Order ID – the original order or transaction identifier used when the file was stamped.
Marked From Domain – the website domain that originally generated and stamped this document.
Fingerprint ID (FID) – a short fingerprint derived from the order id and a secret key, used to look up the original mark event.
Pages Analyzed – how many pages in this file were scanned by the detector.
Decision – the final verdict (for example, match / mismatch / inconclusive) based on the internal scores.
Confidence – how strong the detected fingerprint signal is, shown as a percentage (0–100%).
Layout similarity – a 0–1 score describing how similar the layout of this file is to the originally stamped document (higher = more similar).
Channels – per-channel fingerprint metrics (for forensic/debug use); most users can ignore these.
Statistical Notes – extra diagnostic fields under notes that document how the classifier reached its decision.
