This section describes how to create new masking formats using Enterprise Manager.
To create a masking format in the format library:
From the Enterprise menu, select Quality Management, then Data Masking Formats. Alternatively, if you are in the Database home page, select Data Masking Format Library from the Schema menu.
The Format Library appears with predefined formats that Oracle Enterprise Manager provides.
Click Create.
The Create Format page appears, where you can define a masking format.
Provide a required name for the new format, select a format entry type from the Add list, then click Go.
A page appears that enables you to provide input for the format entry you have selected. For instance, if you select Array List, the subsequent page enables you to enter a list of values, such as New York, New Jersey, and New Hampshire.
Continue adding additional format entries as needed.
When done, provide an optional user-defined or post-processing function (see "Providing User-defined and Post-processing Functions"), then click OK to save the masking format.
The Format Library page reappears with your newly created format displayed in the Format Library table. You can use this format later to mask a column of the same sensitive type.
