* HIPAA (Health Insurance Portability and Accountability Act)

** What it is

US federal law enacted 1996. Governs how protected health information (PHI)
is stored, transmitted, and accessed. Two relevant rules:

- **Privacy Rule:** controls use and disclosure of PHI. Patients have rights
  to access, amend, and request accounting of disclosures. Minimum necessary
  standard — only the minimum PHI needed for the task may be used.
- **Security Rule:** administrative, physical, and technical safeguards for
  electronic PHI (ePHI). Requires access controls, audit controls, integrity
  controls, person/entity authentication, and transmission security.

** Who must comply

Covered entities (health plans, healthcare clearinghouses, healthcare providers
who transmit any ePHI) and business associates (any vendor handling PHI on behalf
of a covered entity). Business Associate Agreements (BAAs) are mandatory.

** Penalties

Tiered civil penalties: $100-$50,000 per violation, up to $1.5M per year per
violation category. Criminal penalties for knowing misuse (up to 10 years
imprisonment). State AGs can also bring civil actions.

** Why it matters for Passepartout

HIPAA is the largest single compliance market in US healthcare — every hospital,
clinic, insurer, and health-tech vendor must comply. The [[id:c34940cc-090e-57c4-8020-e78b1d32b96c][HIPAA gate package]]
($50K/yr) encodes the Privacy Rule and Security Rule as ACL2-verifiable gate
constraints. Every PHI access attempt passes through the gate stack, producing
a machine-checkable audit trail that satisfies the Security Rule's audit control
requirement automatically. No separate logging infrastructure needed. Over a
five-year deployment, the accumulated fact store and proof history create
