Personally Identifiable Information
Personally Identifiable Information (PII) means information that can be used to distinguish or trace an individual's identity, either alone or when combined with other personal or identifying information that is linked or linkable to a specific individual. Some PII is available in public sources such as telephone books, websites, and university listings. The definition of PII is not attached to any single category of information or technology. Instead, it requires a case-by-case assessment of the specific risk that an individual can be identified. Non-PII can become PII whenever additional information is made publicly available, in any medium and from any source, that could be used to identify an individual when combined with other available information.
