Given the purpose of the IG, I am unsure why there is discussion around "de-Identification, pseudonymization, [and] anonymization.".

Existing Wording:

The FHIR Security and Privacy Module describes how to protect a patients privacy through de-Identification, pseudonymization, anonymization. FHIR does not mandate a single technical approach to security and privacy; rather, the specification provides a set of building blocks that can be applied to create secure, private systems.
