Advanced Masking Rules

Advanced Masking Rules

An advanced masking rule is a combination of masking techniques that mask multiple source columns or a target column based on values of more than one input column.
For example, you can create a full masked name by masking the first name and last name input columns. Define variable columns to contain the masked names. Add an output column that contains a result of an expression that combines the first name and last name variable columns.
Create the following types of columns in an advanced rule:
Input
The source column that you want to mask.
Variable
A column that contains intermediate values in a calculation. The variable column receives a value from an expression or a masking technique. You can configure multiple variable columns in order to combine multiple masking techniques.
Output
The target column that receives the masked value. The output column type contains a masking technique and masking parameters.
