Package com.tnsai.guardrails.pii

Class PiiInputSanitizer

java.lang.Object

com.tnsai.guardrails.pii.PiiInputSanitizer

All Implemented Interfaces:

InputSanitizer

public final class PiiInputSanitizer
extends Object
implements InputSanitizer

Replaces common PII with stable type-specific tokens.

Patterns are intentionally heuristic and high precision rather than jurisdiction-complete: email addresses use a practical RFC-like shape; phones require an international prefix or a 10-digit local form; IBANs use the ISO country/check-digit shape; cards require a Luhn-valid 13–19 digit shape; national identifiers cover US SSN and checksum-valid Turkish identity forms. Raw matches are used only during the current call and are never included in diagnostics.

Since:

0.14.0 (TAN-3016)
