Masking String Values

Configure random masking to generate random output for string columns. To configure limitations for each character in the output string, configure a mask format. Configure filter characters to define which source characters to mask and the characters to mask them with.

You can apply the following masking rules for a string port:

Range: Configure the minimum and maximum string length. The Data Masking transformation returns a string of random characters between the minimum and maximum string length.
Mask Format: Define the type of character to substitute for each character in the input data. You can limit each character to an alphabetic, numeric, or alphanumeric character type.
Source String Characters: Define the characters in the source string that you want to mask. For example, mask the number sign (#) character whenever it occurs in the input data. The Data Masking transformation masks all the input characters when Source String Characters is blank.
Result String Replacement Characters: Substitute the characters in the target string with the characters you define in Result String Characters. For example, enter the following characters to configure each mask to contain uppercase alphabetic characters A - Z:; ABCDEFGHIJKLMNOPQRSTUVWXYZ
