Section 1
The premise
If the model never sees PII, you cannot leak it through a prompt-injection attack.
What AI does well here
- Detect emails, phones, SSNs with deterministic regex
- Replace with stable tokens like <USER_1>, <EMAIL_1>
What AI cannot do
- Catch every form of PII (e.g., free-text addresses)
- Substitute for a legal review of your data flow
