Document verification

Verify a document hasn’t changed.

Compare a file against its CREDA-Stamp record to confirm whether it matches the original version. Verification is performed locally in your browser.

Verify File Create Record

Verify a file

Confirm whether a document matches its original recorded version.

Why verification matters

In legal matters, disputes can arise when multiple versions of a document exist. Without a reliable reference, it can be difficult to prove which version is original.

CREDA-Stamp allows you to independently verify whether a file matches the version that was previously recorded.

Privacy: Verification occurs locally in your browser. Files are never uploaded or stored.

A successful match confirms the file is identical to the recorded version. It does not certify authorship, authenticity, or legal validity.
