Add a dictionary in the

Administrator | Dictionaries

view that you want to use in data masking or data generation rules. When you create a masking rule, you can define the dictionary that you want to use to mask sensitive data. Before you create a data generation rule, you must add dictionary to TDM.

The

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.

You can create a generation rule to load the dictionary into target databases. The binary data type contains a serial number column that increases performance. You can configure serial number for relational databases when you create a data generation rule for binary data type.
