Applying the PII data class to a column

About this task

By default, the PII data class exists in the Talend Data Catalog dictionary.

You need to configure this data class to be able to hide data by assigning Highly Confidential sensitivity label. When applying this data class, you identify a data asset as sensitive and its data is hidden automatically from unauthorized users.


  1. In the search box, type in email columns.
    The email_address columns from the ACME customer hub database display in the search results.
  2. On the toolbar, click Columns and select the Grid view.
  3. Drag and drop the Data Classifications column from Available columns to Selected columns to display it.
  4. Verify that the PII data classification has been assigned to the columns. If not, right-click the data classification, select Edit and add the PII value.
  5. Open the object page of the anonymized_orders table.
  6. Click the Data Sample tab.
    The email_address column data is grayed out.
    When previewing sample data from the anonymized_orders table without the Data Manager security role, data values of PII are replaced with a string of # number signs.


When the data class is approved, the sensitivity label is automatically approved and applied.

You are ready to tag the table to indicate that it is compliant with the data protection rules.

You can view hidden data only if you have been assigned an object role with the Data Management capability.
