How do the Financial lexicons work?
Posted by Carlos Rios on 17 November 2017 07:29 PM

Personal Financial Lexicons consist of a set of 3 lexicons: financial terms, financial identifiers and credit card numbers.  These lexicon files are designed to work in combination to recognize “Nonpublic Personally Identifiable Financial Information” (PFI) as defined in the Gramm-Leach-Bliley Act (GLBA).  The lexicons work together to recognize the intersection of financial identifiers, such as SSNs, account numbers or loan numbers AND financial terms, such as balance transfer, refinance or deposit.


The Credit Card Number Lexicon can identify most credit card numbers and bank card numbers with matching technology that recognizes the identifiable patterns of numbers that all major credit card companies and banks use.  Major credit card companies and banks use standard numbering sequences that are unique to each brand of card, such as Visa, MasterCard, or Discover.
