To protect real names, places, or other values with realistic results, it's best to use a lookup value to assign fake, but still real-looking values to each source value. The IRI Workbench GUI for FieldShield supports pseudonyms that may or may not be reversed.

Apply the field rule for Pseudonym Replacement to create a pseudonym field that uses values in a set file as substitutes for the original values in a field. The original values are not recoverable.

Pseudonym Replacement Field Rule

FieldShield also supports the recoverable use of randomly selected pseudonyms, as well as set files or look-up tables that can be used to display and reverse pseudonyms associated with real values. This is accomplished using the Pseudonymize & Restore function in the Target Field editor.
