Best Project for Real-Time Online Payments Fraud Detection Using Machine Learning

Online Payments Fraud Detection Project Idea !!

Project Details

Project Summary

In todays digital economy, online payment fraud continues to threaten individuals and organizations. This Online Payments Fraud Detection web application is a free, open-source, and professionally built solution developed to predict fraudulent online transactions in real-time using machine learning models.

The heart of this application is an XGBoost-based fraud detection model, which delivers an impressive AUC ROC score of 0.9556. The interface, built with Streamlit, allows users to input transaction details and get immediate insights into whether a transaction is likely to be fraudulent or genuine.
