Financial systems demand strong security guarantees while still enabling high-value analytics. This session examines how homomorphic encryption (HE) and GAN-based synthetic data can advance secure financial intelligence in alignment with OWASP’s mission of building trustworthy systems.
Homomorphic encryption enables computation on encrypted data without ever decrypting it, eliminating exposure of sensitive financial records during analysis. Modern GPU-optimised HE frameworks now support SQL-like queries and lightweight machine-learning inference directly on encrypted transaction datasets, bringing performance close to traditional execution and reducing operational overhead previously associated with secure multi-party approaches. Integrating HE into ETL and analytics workflows strengthens defences against data exfiltration, insider threats, and misconfigured infrastructure, while supporting GDPR and PCI-DSS compliance.
Complementing HE, GAN-powered synthetic data generation using models such as TimeGAN and Tabular GAN creates statistically realistic financial datasets that preserve behavioural patterns, including rare anomalies and seasonal variation, without retaining identifiable information. These synthetic datasets allow teams to develop fraud detection models that converge faster, conduct secure cross-team data sharing, and perform stress testing without risking real customer data.
