The original comes first
Text read by character recognition, the straightened version, the thumbnail or the watermark are extra representations. They never rewrite the original.
The fingerprint
When the document arrives, KUP computes its SHA-256 fingerprint. A mismatch later is an incident to investigate. The fingerprint is never recomputed to make it go away.
The log and the attestation
The audit log is sealed. KUP can issue an integrity attestation for a document.
Disposal
Nothing is erased: documents are disposed of by a logged action, with a disposal slip. The metadata record outlives the file.
What KUP does not do
KUP does not replace a public officer.
