When you mask numeric data, you can configure a range of output values for a column. The Data Masking transformation returns a value between the minimum and maximum values of the range depending on port precision. To define the range, configure the minimum and maximum ranges or configure a blurring range based on a variance from the original source value.
You can configure the following masking parameters for numeric data:
Range
Define a range of output values. The Data Masking transformation returns numeric data between the minimum and maximum values.
Blurring Range
Define a range of output values that are within a fixed variance or a percentage variance of the source data. The Data Masking transformation returns numeric data that is close to the value of the source data. You can configure a range and a blurring range.
