SSN Masking

SSN Masking

SSN masking applies a built-in mask format to change Social Security numbers. Mask string datatypes with SSN masking.
Data Integration Service
generates valid Social Security numbers. To avoid generating numbers that the Social Security Administration has already issued, you can download the latest version of the High Group List at the following location:
Data Integration Service
accesses the latest High Group List from the following location:
<PowerCenter Installation Directory>\infa_shared\SrcFiles\highgroup.txt
Data Integration Service
generates Social Security numbers that are not on the High Group List.
The SSN masking accepts any SSN format that contains nine digits. You can delimit the digits with any set of characters. For example, the SSN masking accepts the following format:
You can configure repeatable masking for Social Security numbers. Select the
Repeatable Output
option, select the
option, and enter a value.
Data Integration Service
returns deterministic Social Security numbers with repeatable masking. The
Data Integration Service
cannot return all unique Social Security numbers because it cannot return valid Social Security numbers that the Social Security Administration has issued.

SSN Randomization

The Social Security Administration developed a method to randomize the nine-digit SSN. This method eliminates the geographical significance of the first three digits of SSN and protects the integrity of the Social Security numbers.
When you configure SSN masking parameters, you can use the SSN randomization technique to mask a Social Security number.
