H33-74 for HIPAA

Health Insurance Portability and Accountability Act — Privacy, Security, and Breach Notification Rules (United States, covered entities and business associates handling protected health information) places obligations on organizations to demonstrate that operational controls were in place, that automated decisions were governed, and that an audit trail exists for regulatory inquiry. Most existing audit-log architectures meet the letter of the requirement but produce evidence tied to the operator's current systems. If those systems change or fail, the evidence weakens.

What HIPAA requires

HIPAA requires covered entities and business associates to implement administrative, physical, and technical safeguards for protected health information. Section 164.528 requires an accounting of disclosures, including the date, recipient, purpose, and minimum-necessary determination for each disclosure of PHI. The Security Rule requires audit controls (164.312(b)) that record and examine activity in systems containing electronic PHI.

Why H33-74 fits

HIPAA audit obligations span the lifetime of the patient record and frequently outlast the EHR vendor, the cloud platform, and the staff who made the original disclosure decisions. H33-74 produces each accounting entry, each minimum-necessary determination, and each access event as a cryptographically verifiable post-quantum proof. The Office for Civil Rights inquiry years after a disclosure is answered with the original proof rather than the trust of the operator's current log integrity.

Control mapping

What this changes for the audit team

• Each control's evidence is a cryptographic object the auditor verifies directly, not a log entry the auditor trusts because the operator says so.
• The audit horizon extends beyond the operator's current systems, vendors, or chain choices.
• Regulator inquiry years after a decision can be answered with the original PQ-signed proof rather than reconstructed from operator memory.
• Independent third-party verification works without the operator's infrastructure being available.

None of this redefines the primitive: H33-74 produces/anchors the same portable 74-byte post-quantum receipt for HIPAA that it does for any other use, and it produces evidence that supports HIPAA requirements rather than making a covered entity compliant on its own. How anyone checks a receipt — recompute the commitment, verify the signatures, confirm the anchor, with H33 not in the loop — is described under Verification.
