Proof Infrastructure for Healthcare

Prove that consent was obtained, care processes ran, and data was handled correctly — without exposing protected health information.

The problem

Healthcare organizations must demonstrate that consent was captured, clinical and administrative processes were followed, and patient data was accessed and handled according to policy. This evidence is spread across systems and bound tightly to protected health information (PHI).

Proving compliance or resolving a dispute typically means surfacing PHI or trusting internal logs — a poor trade-off when privacy obligations are strict and penalties for exposure are severe.

The trust gap

The most sensitive evidence is exactly the evidence you cannot freely share. Redaction breaks the link between the evidence and the event, while access to raw records creates privacy and regulatory risk. Traditional logs also can’t prove, to an outside party, that a consent or process step genuinely occurred.

The Proof Infrastructure approach

A proof artifact in this context

Proof artifact sealed
type:proof_of_event
event:Patient consent captured for data processing
issuer:org:metrohealth / system:consent-service
data_commitment:sha256:c30a…9b71
signature:ed25519:5f22…ab19

Sensitive details are committed to via a hash — the proof carries no private data.

Example verification flow

  1. 1An auditor requests evidence that valid consent preceded a data-processing activity.
  2. 2They receive the consent proof artifact — containing no PHI.
  3. 3They validate the signature and issuer authority of the consent service.
  4. 4They confirm the timestamp shows consent was captured before processing.
  5. 5Compliance is demonstrated without exposing the patient’s record.
