FHIR Document Digital Signatures

Healthcare Exchange Standards

I was asked about Digital Signatures for FHIR documents: I am working on __ IG that is FHIR document based and we need a means to prove authenticity.

FHIR enabling an immunization registry

HAY on FHIR

It’s currently fed by HL7 version 2 messages and there’s a User Interface for authorized users, but there was always a plan to introduce a FHIR interface to some point – something that has been accelerated by the current COVID pandemic of course. So what would a FHIR API look like? This does seem a bit of a stretch though….
