Personally identifiable information (PII) is any combination of data points that can lead to the identification of a specific individual (you). This can mean things such as your name or email address, but most times PII refers to "sensitive PII" such as Social Security number (SSN), driver's license number, state identification number, or financial account numbers. Sensitive PII can also exist if PII is combined with another piece of information about you such as a birth date, medical information, or even passwords. The more pieces of data combined about an individual, the more valuable and sensitive the body of information becomes.
