Verify a Report's Authenticity
Anyone holding a reference number can independently check whether a case's full record has ever been silently altered — no login required.
How this works: every action on a case — the report being filed, an AI match being computed, an officer confirming or rejecting it, a claim or a sighting being logged — is recorded as a link in a hash chain. Each entry's SHA-256 hash is built from the entry before it, and is then digitally signed with a secret key that lives outside the database, on the server only.
If anyone ever edited or deleted an entry directly in the database — something a paper case file offers no protection against at all — the hash chain would break and the signatures would no longer verify. That break is exactly what this page checks for, in public, for any case.
