Type Alias SensitivityLevel

DataClassifier

Tags model fields with sensitivity classifications (PII, PHI, PCI, etc.) to enable other compliance classes to auto-identify sensitive data. Stores classifications in model metadata for runtime discovery.

Covers ~25 compliance frameworks including: NIST CSF, NIST SP 800-122, FIPS 199, ISO 29101, China Data Security Law, PIPL, AI Act EU, GDPR Art 25/30/32, and data classification requirements.

Usage:

  // Tag fields with sensitivity levels:
  @Classify('PII')
  @FieldClassification('email', 'PII')
  @FieldClassification('ssn', 'PHI')  // PHI = Personal Health Information
  @FieldClassification('creditCard', 'PCI')
  @FieldClassification('salary', 'CONFIDENTIAL')
  class User extends Model { ... }

  // Query classifications:
  const fields = DataClassifier.getPIIFields(User);
  const classification = DataClassifier.getClassification(User, 'email');
  const all = DataClassifier.getClassifications(User);

  // Auto-discover fields by name patterns:
  DataClassifier.autoDiscover(User, ['ssn', 'social', 'dob', 'card', 'password']);
