Numeric Random Masking Parameters

Numeric Random Masking Parameters

When you mask numeric data, you can configure a range of output values for a column.
The PowerCenter Integration Service returns a value between the minimum and maximum values of the range depending on column precision. To define the range, configure the minimum and maximum ranges or a blurring range based on a variance from the original source value.
The following table describes the parameters that you can configure for random masking of numeric data:
Parameter
Description
Range
A range of output values. The PowerCenter Integration Service returns numeric data between the minimum and maximum values.
Blurring Range
A range of output values that are within a fixed variance or a percent variance of the source data. The PowerCenter Integration Service returns numeric data that is close to the value of the source data. You can configure a range and a blurring range.
