Random Masking

Random Masking

Random masking produces random, non-repeatable results for the same source data and masking rules.
Random masking does not require a seed value. The results of random masking are non-deterministic. Use random masking to mask date, numeric, and string data types.
The following table describes the options that you can configure for random masking:
Option
Description
Range
A range of output values. The
Data Integration Service
returns data between the minimum and maximum values. You can configure a range for date, numeric and string data types.
Blurring
A range of output values with a fixed or percent variance from the source data. Returns data that is close to the value of the source data. You can configure blurring for date and numeric data types.
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. You can configure a mask format for the string data type.
Source String Characters
The characters in the source string that you want to mask. You can configure source string characters for the string data type.
Result String Replacement Characters
Substitutes the characters in the target string. You can configure replacement characters for the string data type.
