Default classifications and datasets
Published 06 November 2023
PII Linked Information
Looking for a classification type, but can't find it among our defaults?
Our default classification types are designed to cover NIST's definition of linked information.
By masking these types of data, you minimize the chance of any other parts of the record being identifiable as the individual.
If you still want to assign classification types or datasets that do not appear in our defaults, see Custom configuration.
A predefined set of classification types and datasets are provided. For each column that the tool classifies as containing sensitive data, one of the classification types and corresponding datasets in the table below will be used.
For some datasets, it is useful to enable determinism by default. Those columns will be set to deterministic: true in the Masking file by default.
