QEI Healthcare

Confirm the person. Expose only what the care process needs.

A QEI research application for sensitive healthcare environments where patient identity, professional role or access entitlement must be verified while keeping unrelated identity data out of the transaction.

RESEARCH APPLICATION AREA
01 / RESEARCH QUESTION
Can identity verification become a narrow trust layer around healthcare — without QEI becoming a medical-record database?
WHAT QEI WOULD VERIFY

Verify what is needed.

  1. Patient identity or pseudonymous patient binding
  2. Professional role or authorised access
  3. A specific entitlement required by the procedure
WHAT IT SHOULD NOT DO

Do not expand the purpose.

  1. Medical diagnosis inside the identity token
  2. Unnecessary exposure of a complete patient profile
  3. Broad access simply because identity was verified once
02 / CONCEPTUAL FLOW

From request to verifiable result.

01

Care event

A patient or authorised professional starts a protected procedure.

02

Role and identity check

QEI verifies the minimum identity or role attributes required.

03

Bound proof

A purpose-limited proof is generated for that healthcare transaction.

04

Controlled access

The healthcare system applies its own access rules and records the event.

03 / SAFEGUARDS

Technology without boundaries is not the QEI objective.

01

Identity ≠ health record

QEI should verify access and identity; it should not become a repository of medical records.

02

Role separation

Patient, clinician, institution and audit functions require clearly separated roles.

03

Revocation

Lost, compromised or expired credentials must be revocable.

04

Auditability

Sensitive access events should be recorded and independently reviewable.

04 / STATUS

A research concept. Not an implemented system.

The healthcare use case is conceptual. Any real deployment would require integration with healthcare law, clinical workflows, existing identity infrastructure, cybersecurity controls and data-protection governance.
