Dictionaries Overview

Dictionaries Overview

A dictionary is a relational table that contains substitute data and a serial number. You can use a dictionary to replace sensitive data in a table.
Add a dictionary in the
Administrator | Dictionaries
view that you want to use in data masking rules. When you create a masking rule, you can define the dictionary that you want to use to mask sensitive data.
The
Data Integration Service
generates a number and retrieves a dictionary row based on the serial number from the dictionary. It generates a hash key for repeatable masking or a random number for non-repeatable masking. You can configure an additional lookup condition if you configure repeatable masking.
When you use dictionaries for masking Hadoop sources, you need to activate the Content Management Service because the dictionary reference tables are created in the Content Management Service database.
