PII looks for drivers license, date of birth, social security number and ACH numbers.
DOB - We match on various date formats used in and around the world within proximity of certain keywords that signify date of birth.
For SSN,ACH, and DL - We don’t just look for any pattern but we look for the combination of trigger terms and patterns. For instance:
SSN: 555555555 would trigger but
555555555 in a file by itself wont.
