Class KMapEstimationConfig (3.10.1)

KMapEstimationConfig(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Reidentifiability metric. This corresponds to a risk model similar to what is called "journalist risk" in the literature, except the attack dataset is statistically modeled instead of being perfectly known. This can be done using publicly available data (like the US Census), or using a custom statistical model (indicated as one or several BigQuery tables), or by extrapolating from the distribution of values in the input dataset.


quasi_ids MutableSequence[]
Required. Fields considered to be quasi-identifiers. No two columns can have the same tag.
region_code str
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.
auxiliary_tables MutableSequence[]
Several auxiliary tables can be used in the analysis. Each custom_tag used to tag a quasi-identifiers column must appear in exactly one column of one auxiliary table.



AuxiliaryTable(mapping=None, *, ignore_unknown_fields=False, **kwargs)

An auxiliary table contains statistical information on the relative frequency of different quasi-identifiers values. It has one or several quasi-identifiers columns, and one column that indicates the relative frequency of each quasi-identifier tuple. If a tuple is present in the data but not in the auxiliary table, the corresponding relative frequency is assumed to be zero (and thus, the tuple is highly reidentifiable).


TaggedField(mapping=None, *, ignore_unknown_fields=False, **kwargs)

A column with a semantic tag attached.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
