String Key Masking Parameters

String Key Masking Parameters

Configure string key masking to mask all or part of a string. To limit the masking output to certain characters, specify a mask format and result string replacement characters. If you need repeatable output, specify a seed value.
The following table describes the masking parameters that you can configure for key masking string values:
Parameter
Description
Case Insensitive
Ensures that the rule masks an input character to a different character. If you do not choose this option, a successful masking task might change the case of a character and the not the character. For example, an input character "x" might get masked to "X."
Seed
A start number that enables the
Integration Service
to return deterministic data. Select a seed value between 1 and
1,000
. Apply the same seed value to a column to return the same masked data values in different source data.
You can choose to use a parameter to provide the seed value at run time.
Mask Format
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
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. Leave this field blank to mask all the input characters. The
Integration Service
does not always return unique data if the number of source string characters is less than the number of result string characters.
Result String Replacement Characters
Substitutes the characters in the target string. For example, enter the following characters to configure each mask to contain uppercase alphabetic characters A through F:
ABCDEF
Delimited String Masking
Consistently masks a given substring of data. Select if you use Key masking technique to mask columns where the substrings occur as strings.
Delimiters
Required if you choose Delimited String Masking. Enter the delimiters that you want to use to split string data to substrings.
