Personally identifiable information (PII) is any information related to an identifiable person. It is also known as personal data or personal information. PII can be used to identify, contact, or locate a specific individual. Examples of PII include name, address, social security number, date and place of birth, mothers maiden name, biometric records, and other identifying information. PII can be direct identifiers that can identify a person uniquely or quasi-identifiers that can be combined with other quasi-identifiers to successfully recognize an individual. The security of PII is paramount, and it is essential to protect individuals identity and any pieces of identifying information unique to them.
