The Delphix Masking Engine provides a "Min Max algorithm" to normalize data within a range – for example, 10 to 400. 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.
If the Out of range Replacement Values checkbox is selected, a default value is used when the input cannot be evaluated.
Creating a Min Max Algorithm via UI¶
Enter the Algorithm Name.
This MUST be unique.
Enter a Description.
Enter Min Value and Max Value.
Click Out of range Replacement Values.
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 Value 0 and Max Value 18.
