Compliant test data for banking and payments

The Compliance Challenge

Financial applications require:

  • PCI-DSS compliance: Masked credit card numbers
  • SOX compliance: Audit trails, immutable logs
  • Realistic transactions: Power-law amounts, temporal patterns
  • Fraud detection: Anomalous patterns for ML training
  • Multi-currency: Exchange rates, conversions
