Masking Rules

Masking rules are the options that you configure after you choose the masking technique.

When you choose the random or key masking technique, you can configure the mask format, the source string characters, and the result string characters. You can configure range or blurring with random masking.

The following table describes the masking rules that you can configure for each masking technique:

Returns a string of random characters between the minimum and maximum string length. Date/Time. Returns a date and time within the minimum and maximum datetime.	Random	Numeric String Date/Time
Blurring	Range of output values with a fixed or percent variance from the source data. The Data Masking transformation returns data that is close to the value of the source data. Datetime columns require a fixed variance. columns require a fixed variance.	Random	Numeric Date/Time
