Which technology enables real-time fraud detection in digital payments using pattern analysis?
- Blockchain
- Machine Learning
- OCR
- SMS Gateway
Answer: Machine Learning
ML models analyze transaction patterns (amount, location, time, device) to detect anomalies indicating fraud. Techniques: supervised learning (labeled fraud data), unsupervised anomaly detection, and real-time scoring. Used by banks, UPI apps, and payment gateways. Continuous learning adapts to evolving fraud tactics while minimizing false positives.
