Personally Identifiable Information (PII) protection is critical for AI systems to prevent privacy breaches and ensure compliance. There can be two ways to deal with PII:
  1. Validate: Validate the input and reject the input if it contains PII. (raise a 400 error)
  2. Mutate/Mask: Mask the PII data in the input. (replace the PII data with a placeholder)

​
Example of PII Data

Input: "My name is John Smith, SSN is 123-45-6789, email john@company.com"
Output: "My name is {REDACTED} SSN is {REDACTED}, email {REDACTED}"

​
Types of PII Data

  • Direct identifiers: Names, Social Security numbers, driver’s license numbers, passport numbers
  • Contact information: Email addresses, phone numbers, home addresses
  • Financial data: Credit card numbers, bank account details, routing numbers
  • Biometric data: Fingerprints, facial recognition data, voice prints
  • Digital identifiers: IP addresses, device IDs, online usernames

​
