The problem
Clinical records need to be provably unaltered, but they can never be published to a public ledger.
01
What is anchored
Reports and readings, anchored as fingerprints only. Patient data stays in the clinical system.
02
When it is revealed
Anchored at capture; disclosed only to those already entitled.
03
Who checks it
Auditors, insurers and patients — against the anchor, not against the record.
Privacy mode
Fingerprint only — nothing leaves the clinical system.
The cycle is identical
Canonicalise the artifact, hash it with a secret nonce, anchor the fingerprint, then reveal inside the window. Only the schema and the window change from one application to the next.
