Using the Data Anonymizer Component

The Data Anonymizer Component is a transformation component used to mask data. Select columns to mask and select their anonymization type. The values in these columns will be replaced with randomly generated data based on the anonymous type selected.

Columns Page

Select a column in the data grid view and configure its anonymization settings in the property grid to the right.

Data Anonymizer Editor - Columns Page

Anonymization Type

Displays the Anonymization Type selected from the Anonymizer Properties setting to generate random data.

Anonymizer Properties

The following are the Anonymization Types available for selection, some Anonymization Types have additional properties that can be configured:

Expression fx Button 

Clicking the fx button to launch SSIS Expression Editor to enable dynamic update of the property at run time.

Generate Documentation Button 

Clicking the Generate Documentation button to generate a Word document which describes the component's metadata including relevant mapping, and so on.

Error Handling page

The Error Handling page allows you to specify how errors should be handled when they happen. 

Data Anonymizer Editor - Error Handling Page

There are three options available. 

  1. Fail on error
  2. Redirect rows to error output
  3. Ignore error

When the Redirect rows to error output option is selected, rows that failed to be anonymized will be redirected to the 'Error Output' output of the Transformation Component. As indicated in the screenshot below, the blue output connection represent rows that were successfully anonymized, and the red 'Error Output' connection represents rows that were erroneous. The 'ErrorMessage' output column found in the 'Error Output' may contain the error message that was reported by server or the component itself.
