Question

identifying protected personal information (ppi)
two students at a school have the same name and share the same birth month and year
which information can be used to distinguish the two students? choose four correct answers
their passwords their name their pin number their phone number
their social security number their age

Explanation:

1. their passwords: Unique to each user, so can distinguish.
2. their PIN number: Unique identifier for each individual.
3. their phone number: Each student likely has a unique phone number.
4. their social security number: Unique to each person, so useful for distinction.

• "their name" is same for both, "their age" same (same birth month/year implies similar age), so these don't help.

Answer:

A. their passwords, C. their PIN number, D. their phone number, E. their social security number
