Class PiiInputValidator

java.lang.Object
com.tnsai.guardrails.pii.PiiInputValidator
All Implemented Interfaces:
InputValidator
public final class PiiInputValidator extends Object implements InputValidator
Heuristic detector for common PII carried in action parameters.

The detector recognizes practical email and phone forms, IBAN-shaped identifiers, Luhn-valid 13–19 digit payment-card numbers, US SSN-shaped identifiers, and checksum-valid Turkish national identity numbers. It is deliberately not a legal or jurisdiction-complete PII classifier.

Since:
0.14.0 (TAN-3016)

  • Method Details

    • isValid

      public boolean isValid(String input)
      Description copied from interface: InputValidator
      Returns whether the value is safe to dispatch.
      Specified by:
      isValid in interface InputValidator
      Parameters:
      input - string parameter value, never null
      Returns:
      true when the value may continue through the action pipeline

    • validatesParameterNames

      public boolean validatesParameterNames()
      Description copied from interface: InputValidator
      Returns whether this validator also protects parameter names before value validation. Domain validators normally leave this disabled; security classifiers that treat keys as user-visible prompt data may opt in.
      Specified by:
      validatesParameterNames in interface InputValidator
      Returns:
      true when parameter names must pass InputValidator.isValid(String)
