2. Patient A visits Organization A for an appointment; Organization A identity proofs Patient A and collects information during patient registration - Prerequisite: other testing participants know Patient A details, which can be shared on this worksheet
- Prerequisite: systems agree on a target "fake" Patient A and associated demographics (for example, Alice Newman)

4. B2C scenario with UDAP Tiered OAuth, with Identity IG's Digital Identity including an OpenID Connect credential (with an authenticator), and Digital Identifier within the user profile Workflow similar to Scenario 3 except a Client application's access to data at Organization B is authorized by Patient A in consumer-directed exchange via UDAP Tiered OAuth and with JWT-based Authentication B2C (instead of B2B) | Scenario Steps | Roles | Components Needed | Documentation | Value |
|---|

- FHIR server answering initial discovery request is going to provide the location of its registration endpoint as publicly accessible URL
Bonus Point: Organization A is using an untrusted, expired, or revoked certificate and Organization B therefore does not allow registration
Bonus Point: Organization A's signed JWT validates and its certificate is otherwise good but it does not chain to a trusted issuer so Organization B therefore does not allow registration
Bonus Point: Organization A's signed JWT does not validate as it is signed with a key other than the one presented so Organization B therefore does not allow registration
| Organization A as Client App capable of UDAP Security B2C |
|
|
| | Organization B as Data Holder capable of UDAP Security B2C (itself or as serviced by Org C) |
|
| | Organization C - Intermediary |

- Bonus Point: Organization B has records for Patient A via exact match on Patient A's Digital Identifier (e.g., Patient A had previously registered their Digital Identity and this Digital Identifier issued by Organization A at Organization B)
- Bonus Point: Organization B has records for Patient A via single high confidence match on demographics in the ID token from Organization A commensurate with those required in IDI Level 1

|
|
|
|

- Bonus Point: ID token includes insufficicent demographics or Digital Identifier is unknkown and is returned with an informative error and no results
- Bonus Point: Identity Service-provided demographics within ID token, if validated per trust policy, are scored by responder's system and used along with Client's credentials as input to data holder's matching capability
- Bonus Point: Organization B performs other out of band interaction with Patient A that enables use of their Digital Identity to access health data
| Organization A as Client App capable of UDAP Security B2C and Patient A as end user |
|
|
| | Organization B as Data Holder capable of UDAP Security B2C |

NOTE: This scenario's steps a-e and the identity portion of f.iii are also exercised in similar workflows, such as when 1) Partner Role: a system's own security environment, OAuth and possibly also identity verification services are outsourced to a trusted credential management partner serving as the UDAP Tiered OAuth IdP or 2) TEFCA Identity Services: a third party IdP is used for identity verification and authentication of Participant Users and indicates a unique Digital Identifier and/or verified demographics per FAST Identity IG directly to a QHIN's UDAP Server.
5. Test sharing demographic attributes within an authorization extension object in UDAP Security's JWT-based authentication B2B (and as per Carequality FHIR IG and UDAP Security IG + FAST Identity IG) in a Patient Access workflow not requiring patient credentials at the responder’s organization | Scenario Steps | Roles | Components Needed | Documentation | Value |

|
| C. Organization A dynamically registers at Organization B public endpoint (UDAP Security - Registration) - Organization B’s public endpoint resolves to intermediary leveraging National Directory Exchange IG

|
|
|
|
|
|
|
| D. Organization A requests access token for Organization B's public endpoint (UDAP Security - Authorization and Authentication - B2B) with verified minimum required demographics for the carequality_user that uniquely specify an individual that is the patient user (FAST Identity) included in the Authorization Extension Object (Carequality FHIR IG) - Validating that the listing obtained from the Directory is in fact from the entity via UDAP Server Metadata
- Intermediary receives token request and routes to Organization B private endpoint
|
|
|
|
|
|
|
| E. Organization B returns an access token if the user is an exact match and intermediary routes response back to Organization A; otherwise an error is returned - Bonus point: requestor provides insufficient demographics and is returned with an informative error and no results
- Bonus point: requestor includes Digital Identifier in Authorization Extension Object and responder's system matches on this identifier on its own or in addition to other demographics
|
|
|
|
|
|
|
| F. Organization A performs a $match operation against Organization B public endpoint and obtains patient ID(s) - Organization B will only return patient ID(s) for patients that the user is authorized to see
