This handbook explains the PROCESS for removing individually identifiable information from healthcare data. This includes de-identification, pseudonymization, re-linking, design considerations, techniques, and risks. The intended audience is IHE Profile editors and healthcare information technology implementers needing a guide for designing and implementing de-identification systems.

### Conformance Expectations

IHE uses the normative words: Shall, Should, and May according to [standards conventions](https://profiles.ihe.net/GeneralIntro/ch-E.html).

#### Must Support

The use of `mustSupport` in StructureDefinition profiles is equivalent to the IHE use of **R2** as defined in [Appendix Z](https://profiles.ihe.net/ITI/TF/Volume2/ch-Z.html#z.10-profiling-conventions-for-constraints-on-fhir).

`mustSupport` only has a meaning on items that are minimal cardinality of zero (0), and applies only to the source actor populating the data. The source actor shall populate the elements marked with MustSupport, if the concept is supported by the actor, a value exists, and security and consent rules permit. The consuming actors should handle these elements being populated or being absent/empty. Note that sometimes mustSupport will appear on elements with a minimal cardinality greater than zero (0), this is due to inheritance from a less constrained profile.
