How to Generate Synthetic UPI Transaction Data for Fraud Detection

India's DPDP Act just made your training data illegal. Here's how to build fraud detection models anyway. Every AI team building UPI fraud detection in India faces the same impossible problem: you need millions of transaction records to train a model, but you can't legally use real user data. The Digital Personal Data Protection Act, 2023 (DPDP Act) — specifically Section 4(1) — requires explicit consent for processing personal data. Section 8(7) mandates data minimization. Real UPI transaction logs contain sender IDs, receiver IDs, amounts, locations, and timestamps — all classified as personal data under the Act. So you're stuck. You can't train without data. You can't use real data without consent. And getting consent from millions of UPI users? Good luck. The answer is synthetic data — algorithmically generated datasets that preserve the statistical properties of real data without containing any actual user information. What is Synthetic Data? Synthetic data is artificially generat
