AI-Powered Fraud Detection & Adaptive Defense (Issue #981)

Summary

This feature deploys a streaming analytics engine with unsupervised machine learning to detect evolving fraud patterns and trigger automated defense actions. It replaces traditional rule-based detection with adaptive, AI-driven mechanisms for real-time fraud prevention.

Features

• Streaming analytics engine for real-time transaction ingestion
• Unsupervised ML (KMeans clustering) for anomaly detection
• Automated defense actions (block, flag, require 2FA, escalate)
• Modular dashboard UI for alerts, defenses, and transaction monitoring
• Utility functions for normalization, risk scoring, and formatting
• Scalable codebase (500+ lines) for extensibility

Benefits

• Detects sophisticated, adversarial fraud tactics
• Adapts to evolving fraud patterns without manual rule updates
• Enables automated, rapid defense responses

Files Added/Modified

• public/fraud-ml-engine.js
• public/fraud-stream-connector.js
• public/fraud-defense-actions.js
• public/fraud-dashboard.js
• public/fraud-dashboard.html
• public/fraud-dashboard.css
• public/fraud-utils.js

How to Use

1. Open fraud-dashboard.html in your browser
2. The dashboard will stream transactions, detect anomalies, and display alerts/defense actions in real time
