Introduction

The anonymize operation is to be used to anonymize the data containing PHI/PII. The approach for anonymization is left to the DARTS service provider.

  • The operation takes a List of Resource URLs that points to identifiable data in NDJSON format and will return back a set of links to NDJSON files that contains the anonymized data.

  • The operation uses the FHIR Async operation pattern documented in the FHIR Async Specification
