Encrypting Multiple Columns to Preserve Referential Integrity [video]
In this demonstration, the Multi-Table Protect Job Wizard in the IRI Workbench GUI for Fieldshield and Voracity is used to define a rule for data in multiple Oracle tables. The rule locates columns that share the same type of data so that a protection rule for personally identifiable information (PII) can be applied to that data in multiple tables at the same time.
