CodeDisplayDefinition
ANONY AnonymizeActivity that removes all personally identifiable information (PII) to prevent re-identification.
DEID De-identifyActivity that removes or obfuscates personal identifiers while retaining data usability.
MASK MaskActivity that hides or replaces specific data elements with placeholder values.
LABEL Assign Security LabelActivity that applies confidentiality, sensitivity, or purpose-of-use labels to data.
PSEUD PseudonymizeActivity that replaces direct identifiers with pseudonyms that can be re-linked under controlled conditions.
CREATE CreateActivity representing the creation of new data or resource instance.
DELETE DeleteActivity representing deletion or removal of a data record.
APPEND AppendActivity representing addition of new information to an existing resource or record.
NULLIFY NullifyActivity that invalidates or renders data non-usable without deleting the record.
LA Legally AuthenticatedActivity confirming legal authentication of a record (e.g., signed or witnessed by authorized person).
