Min Max

Extensible Algorithm Framework

The Delphix Masking Engine provides two Min Max algorithm frameworks: "MinMax Date" and "MinMax Number" to normalize data within a range. Values that are extremely high or low in certain categories allow viewers to infer someone’s identity, even if their name has been masked. For example, a salary of $1 suggests a company’s CEO, and some age ranges suggest higher insurance risk. You can use a Min Max algorithm to move all values of this kind into the midrange. This algorithm allows you to make sure that all the values in the database are within a specified range. The algorithm frameworks are applicable to numeric or date data types.

The Replacement Value for Nonconforming Data value is used when the underlying data to be masked is of type String and conversion to a date or a number is required.

Creating a Min Max Algorithm via UI

  1. Enter the Algorithm Name.


    This MUST be unique.

  2. Enter the Description.

  3. Enter the Min Number and the Max Number.

  4. Enter the Replacement Value for Nonconforming Data if needed.

  5. Click Save.

For information on creating Min Max algorithms through the API, see API Calls for Creating Algorithms - Min Max.


Example: Age less than 18 years - enter Min Number 0 and Max Number 18.
