PII (Personally Identifiable Information)
Privacy
Common term for identifiers that can single out a person; scope differs by jurisdiction and context.
Definition
PII refers to information that can identify an individual, especially direct identifiers (name, email, SSN) and sometimes indirect identifiers when combined. In many privacy frameworks, the broader concept is “personal data.”
Why this matters
Why it matters: PII enables re-identification and targeted harm; strong protection and minimization are essential.
Example
Example: Protect PII with access controls, encryption, and strict retention; avoid storing unnecessary identifiers.
