ordt:redact-us-ssn

ordt:redact-us-ssn(
   $column as item(),
   $options as map:map?
) as map:map

Summary

This function redacts a column with a 9-digit US SSN (Social Security Number) string by generating random numbers or replacing numbers with a masking character. This function can be used with op:bind or op:select.

Usage Notes

The redacted column may have a US SSN value with any of the following formats:

• no punctuation as in 123456789
• blocks of 3, 2, and 4 numbers with the blocks separated by a hyphen, period, or space as in 123.45.6789

The options consist of the following properties:

• level: either full (the default), partial, or full-random; the full level replaces all digits with the masking character; the partial level retains the last 4 digits and replaces all other digits with the masking character; the full-random level replaces all digits with randomly generated digits.
• character: the character that replaces each digit (with # default) for the full or partial level; ignored for the full-random level.
