Custom Masking
Data Masking Your Way
In addition to its many off-the-shelf data masking routines, IRI FieldShield allows you to supply and use your own custom field-level function that FieldShield can use at runtime right alone with its existing functions built-in the same way. This allows you to protect field values in ways that are not natively supported by FieldShield.
