Anonymizing Field Values

Fields that have been selected for anonymization on the Settings tab have their values anonymized:

• When you run the stream containing the Anonymize node
• When you preview the values

To preview the values, click the Anonymize Values button on the Anonymized Values tab. Next, select a field name from the drop-down list.

If the measurement level is Continuous, the display shows the:

• Minimum and maximum values of the original range
• Equation used to transform the values

If the measurement level is anything other than Continuous, the screen displays the original and anonymized values for that field.

If the display appears with a yellow background, this indicates that either the setting for the selected field has changed since the last time the values were anonymized or that changes have been made to the data upstream of the Anonymize node such that the anonymized values may no longer be correct. The current set of values is displayed; click the Anonymize Values button again to generate a new set of values according to the current setting.

Anonymize Values. Creates anonymized values for the selected field and displays them in the table. If you are using random seeding for a field of type Continuous, clicking this button repeatedly creates a different set of values each time.

Clear Values. Clears the original and anonymized values from the table.
