AI Decision Evidence · Healthcare

Cryptographic Evidence for Healthcare AI
backed by proof

Prove that an AI decision over protected health information respected the policy — minimum necessary, access controls, the right reason — with a signed record that contains a digest of the request, never the raw PHI.

The Obligation

What examiners require

These map to concrete EVE Proof capabilities — enforcement, reproducibility, and signed evidence — not a policy PDF.

🔒

HIPAA minimum necessary

Confidentiality guards block disclosure before it happens; the certificate proves the decision without storing the PHI.

🛡

Access control evidence

Each decision records the policy version and reason code — who could act, on what basis, and why.

🩺

Digest, not data

The request is bound by SHA-256 digest, so the evidence is verifiable without ever embedding patient data.

In Practice

Where evidence changes the conversation

1

A disclosure is blocked

When a policy blocks an over-broad PHI disclosure, the certificate records the reason code and policy version — a tamper-evident record of the safeguard working.

2

An auditor reviews access

Hand over an evidence pack scoped to a window or a case; the auditor verifies each decision offline, with no patient data in the bundle.

3

A vendor must show controls

Demonstrate to a covered entity that AI decisions were governed and provable — with evidence they can verify independently.

FAQ

Common questions

Does the certificate contain PHI?
No. It binds the request by SHA-256 digest and records only the verdict, reason code, and policy version — designed so PHI is never embedded in the evidence.
Is this HIPAA compliant?
EVE Proof provides verifiable evidence of minimum-necessary, access-controlled decisions to support a HIPAA program. It is infrastructure, not legal advice.
Can a Business Associate use it?
Yes — it gives a BA a way to prove to a covered entity that AI decisions over PHI were governed and independently verifiable.
