Managing Masking Formats
The masking format is the format in which the output of the reveal operation is presented. Masking formats enable you to display the output data in a particular format. Application Data Protection offers a set of predefined formats that determine how the data will be displayed when the reveal operation is performed. To meet your specific requirement, the Application Data Protection Admins can easily create custom masking formats. While creating a masking format, you can choose to show or hide characters and the masking character - that will be used to mask the data. By default, X is the default masking character. Following are some typical examples of masking operation.
Example 1
Plaintext: 12345678ABCDFRG
Masking Character: X
Masking Operation: Show first 3 characters and last 4 characters.
Masked Data: 123XXXXXXXXDFRG
Example 2
Plaintext: 12345678ABCDFRG
Masking Character: Y
Masking Operation: Mask first 3 characters and last 4 characters.
Masked Data: YYY45678ABCYYYY
