On May 22, 2007, the Executive Office of the President of the United States issued a memorandum concerned with safeguarding personal information, which first defined the term “personally identifiable information” as follows:

[I]nformation which can be used to distinguish or trace an individual's identity, such as their name, social security number, biometric records, etc. alone, or when combined with other personal or identifying information which is linked or linkable to a specific individual, such as date and place of birth, mother’s maiden name, etc.
