Personal identifier

From Wikipedia, the free encyclopedia

Personal Identifiers (PID) are a subset of personally identifiable information (PII) data elements, which identify an individual and can permit another person to “assume” that individual's identity without their knowledge or consent.[1]

Identifiers can be sensitive and non-sensitive, depending on whether it is a direct identifier that is uniquely associated with a person or a quasi-identifier that is not unique. A quasi-identifier cannot pin down an individual alone - it has to be combined with other identifiers.[2]

Examples of PID[edit]

Privately issued ID credentials[edit]

  • Benefit plan participation number
  • Private health care authorization, access, or identification number

Transactional financial account numbers[edit]

Biometric identifiers[edit]

Health or medical information[edit]

  • National Health certificate number

Electronic identification credentials[edit]

Full Date of Birth[edit]

  • Month, day and year

European-defined sensitive data[edit]

Treated as PID globally, not just for citizens of the EU
