Healthcare Credentials

Verifiable health credentials enable privacy-preserving proof of vaccination status, professional licenses, and health records with patient control.

Healthcare & Verifiable Credentials

The COVID-19 pandemic accelerated interest in digital health credentials. Beyond vaccination certificates, verifiable credentials can transform how we manage health records, verify professional qualifications, and protect patient privacy.

Privacy-First Design

Health information is among the most sensitive personal data. Verifiable credentials enable verification without unnecessary disclosure.

Selective Disclosure

Prove vaccination status without revealing which vaccine, date, or location.

Patient Control

Patients decide what to share and with whom, maintaining autonomy over health data.

No Central Database

Verification doesn't require querying a central health record system.

Offline Verification

Critical for field operations where internet connectivity may be limited.

Lessons from COVID-19 Certificates

EU Digital COVID Certificate

European Union

Over 2.3 billion certificates issued across 80+ countries. Demonstrated large-scale VC infrastructure is feasible.

  • Interoperable across 80+ countries
  • Offline verification
  • Privacy-preserving design

SMART Health Cards

VCI Coalition

Open standard adopted by US states and healthcare providers for vaccine records and lab results.

  • QR code based
  • FHIR compatible
  • Widely adopted in US
Key Takeaway
COVID certificates proved that billions of verifiable credentials can be issued and verified globally. The infrastructure built can be repurposed for other health credentials.

Regulatory Considerations

HIPAA Compliance (US)

High

Threat

Health credentials may contain Protected Health Information (PHI) subject to HIPAA regulations.

Mitigation

Design credentials to minimize PHI. Use selective disclosure to share only necessary data. Ensure proper BAAs with wallet providers.

GDPR Considerations (EU)

High

Threat

Health data is a special category under GDPR requiring explicit consent and additional protections.

Mitigation

Implement strong consent mechanisms. Enable data portability. Provide clear privacy notices at presentation time.
