Dependent Masking Example

A data masking dictionary might contain address rows with the following values:

SNO	STREET	CITY	STATE	ZIP	COUNTRY
1	32 Apple Lane	Chicago	IL	61523	US
2	776 Ash Street	Dallas	TX	75240	US
3	2229 Big Square	Atleeville	TN	38057	US
4	6698 Cowboy Street	Houston	TX	77001	US

You need to mask source data with valid combinations of the city, state, and ZIP code from the Address dictionary.

Configure the ZIP port for substitution masking. Enter the following masking rules for the ZIP port:

Configure the City port for dependent masking. Enter the following masking rules for the City port:

Rule	Value
Dependent Column	ZIP
Output Column	City

Configure the State port for dependent masking. Enter the following masking rules for the State port:

Rule	Value
Dependent Column	ZIP
Output Column	State

When the Data Masking transformation masks the ZIP code, it returns the correct city and state for the ZIP code from the dictionary row.
