Please Note:

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

Default Masking Formats

The following table describes the predefined masking formats along with their description. We have also added some examples to make you familiar with the masking operation:
