What does 'nonpublic personal information' refer to?

The term 'nonpublic personal information' specifically refers to personal financial information that is not publicly available. This kind of information includes details such as an individual's bank account numbers, credit card information, income, investment portfolios, and Social Security numbers. The defining characteristic of this type of information is that it is sensitive and private, meaning it has not been disclosed to the general public and is typically protected under privacy laws, such as the Gramm-Leach-Bliley Act.

In contrast, the other options refer to types of information that either do not align with the definition of nonpublic personal information or are inherently public. Information accessible to the public, data solely from government sources, or generalized consumer behavior data do not meet the criteria of being private and confidential financial details. Thus, the identification of nonpublic personal information as personal financial information that remains confidential reinforces the importance of privacy and protection of sensitive data in the financial sector.
