PDF deterministic Identity against Payment-Redirection Fraud

Ordius is a deterministic document identity and integrity protocol that creates a verifiable identity for a document while preserving its original byte-level identity. Create an identity before distribution, then independently verify the document later to determine whether it remains unchanged. Designed for invoices, contracts, certificates, and other important documents where document integrity matters.

I built Ordius around a simple question: once a PDF leaves the hands of the person who created it, how can you know that the document itself is still exactly the same? File names, locations, email threads, and visual appearance don't provide that guarantee. A PDF can be intercepted, modified, renamed, forwarded, and redistributed without an obvious indication that its contents changed. Ordius creates a deterministic identity for the document before distribution, then lets you independently verify that identity later. The goal is simple: give important documents a persistent, embedded, verifiable identity without changing the document's underlying identity. Ordius is live and free to try, with 10 Create Identity and 10 Verify Identity uses every day. I'd love to see what you do with it.
