Hiasobi SMART on FHIR R4

• Implements SMART App Launch Framework as per http://www.hl7.org/fhir/smart-app-launch/
• Auth service is built into Oridashi Hiasobi with the following features:
  • Logged in user clinical system identity is used for authorisation (user authentication)
  • Direct login with Oridashi customer credentials may be performed (where user is not logged into clinical system)
  • Only *.read scopes are supported currently

Registering Applications

• Each customer has a self-managed application register
• Registering application launch and redirect urls is needed to ensure secure launch of applications (Auth service confirms)
• Access application manager at https://hiasobi-manager.azurewebsites.net/ login using customer credentials

Evaluation Suite

• Deploy evaluation adapter to desktop from http://oridashi.com.au/install/OridashiAdapterR4/OridashiAdapterR4.application
• Login to https://hiasobi-manager.azurewebsites.net/ to register applications using credentials samples2 / 67763F1A6A6146D9B5ADA858
• Each customer has their own self managed apps register
• See the registered sample application
  • Id: 4ae955ea-3a6c-4128-8f7b-0d45ca4e4fff
  • Display: Smart App Tester (R4) - sample javascript on these pages
  • Launch Url: https://oridashi.com.au/site/apps/smart-launch2.html (launch sequence, find auth server, redirect to auth server)
  • Redirect Url: https://oridashi.com.au/site/apps/smart-index2.html (destination redirect from auth server, token exchange for access token, example FHIR service call)
  • A Javascript Library is supplied implementing launch and token exchange sequence https://oridashi.com.au/site/apps/smart2.js and used in the example app
• Registered apps appear in the evaluation adapter (right click menu; refresh on restart of adapter)

Hiasobi Identity Scheme

Scope Request (fhirUser), Response: id_token

• user claim details
• id_token contains a JWT (JSON web token)
• See: https://github.com/smart-on-fhir/smart-on-fhir.github.io/blob/master/authorization/smart-on-fhir-jwt-examples.ipynb
• Example token exchange response includes JWT in id_token

}

Example - decoded JWT example; this is a signed JWT with Oridashi certificate

{
  "iss":"https://localhost.oridashi.com.au:8102",
  "sub":"verified\bp.8003628233355286\1",
  "aud":"https://oridashi.com.au/site/apps/smart-index.html",
  "exp":"1460979592",
  "name":"Frederick Smith",
  "profile":"https://localhost:8102/Practitioner/1"
}

Structure - "sub" is the subject of the claim globally unique user identifier

<id status>\<clinical system id>.<site identifer>\<practitioner id> 

<id status>

[verified|unverified|test] 
a) 'test':samples/test mode; samples use always marked test to avoid production mismatch
b) 'verified': by certificate check; only HPI-O can be verified by certificate
c) 'unverified': asserted site id; only windows domain SID or generated instance identity

<clinical system id>

[md|bp|zedmed|genie|mt] - system type identifier 

<site identifier>

a) HPIO as entered and validated against installed eHealth certificate e.g. 8003628233355286
b) Windows domain SID where present e.g. S-1-5-21-7375663-6890924511-1272660413-2944159
c) Ad-hoc uniquely generated site identifier e.g. 57401CE7C397337ABB1B1D237875CCC6

<practitioner id> - internal site resource identifier string for the associated user Practitioner
