Credit Card Masking

Credit Card Masking

Credit card masking applies a built-in mask format to disguise credit card numbers. The
PowerCenter Integration Service
creates a masked number that has a valid checksum. You can choose from multiple credit card number formats. Mask the string datatype with credit card masking.
The
PowerCenter Integration Service
generates a logically valid credit card number when it masks a credit card number. The length of the source credit card number must be between 13 to 19 digits. The input credit card number must have a valid checksum based on credit card industry rules.
You can apply repeatable masking to credit card numbers. Each credit card type has a different format. You can choose to keep the same credit card type in the masked credit card number, or you can change the credit card type. For example, if the source credit card number is a Visa credit card number, you can configure the rule to return a Visa credit card number. Or, you can configure the rule to return a credit card number that is a different credit card type.
The source credit card number can contain numbers, spaces, and hyphens. If the credit card has incorrect characters or is the wrong length, the Integration Service writes an error to the session log. The
PowerCenter Integration Service
applies a default credit card number mask when the source data is not valid.
The
PowerCenter Integration Service
does not mask the six-digit Bank Identification Number (BIN) at the beginning of the number. For example, the
PowerCenter Integration Service
might mask the credit card number
4539 1596 8210 2773
as
4539 1516 0556 7067
