Credit card masking

Credit card masking

Credit card masking applies a built-in mask format to mask credit card numbers. You can create a masked number in the format for a specific credit card issuer.
The Data Masking transformation generates a logically valid credit card number when it masks a valid credit card number. The length of the source credit card number must be from 13 through 19 digits. The input credit card number must have a valid checksum based on credit card industry rules.
The first six digits of a credit card number identify the credit card issuer. You can keep the original credit card issuer or you can select another credit card issuer to appear in the masking results.

Credit card parameters

The following table describes the parameters that you can configure for credit card masking:
Parameter
Description
Repeatable
Returns the same masked value when you run a task multiple times or when you generate masked values for a field that is in multiple tables.
Seed Value
A starting number to create repeatable output. Enter a number from 1 through 999. Default seed value is 190. You can enter the seed value as a parameter.
Keep Issuer
Returns the same credit card type for the masked credit card. For example, if the source credit card is a Visa card, generate a masked credit card number that is the Visa format.
Mask Issuer
Replaces the source credit card type with another credit card type. When you disable Keep Issuer, select which type of credit card to replace it with. You can choose credit cards such as AMEX, VISA, and MASTERCARD. Default is ANY.
