Reference documentation and code samples for the Google Cloud Data Loss Prevention v2 API class PrivacyMetric.Types.DeltaPresenceEstimationConfig.
δ-presence metric, used to estimate how likely it is for an attacker to
figure out that one given individual appears in a de-identified dataset.
Similarly to the k-map metric, we cannot compute δ-presence exactly without
knowing the attack dataset, so we use a statistical model instead.
public RepeatedField<StatisticalTable> AuxiliaryTables { get; }
Several auxiliary tables can be used in the analysis. Each custom_tag
used to tag a quasi-identifiers field must appear in exactly one
field of one auxiliary table.
ISO 3166-1 alpha-2 region code to use in the statistical modeling.
Set if no column is tagged with a region-specific InfoType (like
US_ZIP_5) or a region code.
