🛡️ Dynamic AML Detection Platform

Real-Time Anti-Money Laundering System with Live Data Processing

🌟 Overview

A dynamic Anti-Money Laundering (AML) detection platform that processes financial transactions in real-time through advanced rule-based algorithms. The system features live sanctions data integration, dynamic transaction generation, and a modern web dashboard for real-time monitoring of compliance alerts and risk assessments.

✨ Key Features

🔄 Real-Time Processing - Live transaction monitoring and alert generation
🌐 Live Sanctions Data - Integration with OpenSanctions API and OFAC lists
🎲 Dynamic Transaction Generation - Realistic transaction patterns for testing
📊 Interactive Dashboard - Real-time visualizations and alert management
☁️ Cloud-First Database - Supabase PostgreSQL for transactions, alerts & sanctions with SQLite fallback
⚡ RESTful API - Complete API for external integrations
🔄 Auto-Fallback System - Seamless failover from cloud to local storage
🔐 Multi-Provider Authentication - Secure OAuth2 login with Google, Microsoft, GitHub, Oracle
🎨 Creative Status Indicator - Logo border color indicates system health
🛡️ Enterprise Security - Role-based access control with audit logging

🔐 Authentication & Security

🌟 Multi-Provider OAuth2 Authentication

The AML Controller features enterprise-grade authentication with support for multiple identity providers, ensuring secure access to sensitive financial compliance data.

🎯 Supported Providers

🔍 Google - Gmail and Google Workspace accounts
🏢 Microsoft Azure AD - Corporate Microsoft accounts
👥 GitHub - Developer and organization accounts
☁️ Oracle Cloud - Enterprise OCI identity domains

🎨 Creative System Status Indicator

Instead of traditional status dots, the system uses the company logo border color as a subtle health indicator:

Status	Border Color	Condition
🟢 Healthy	Green	All APIs responding < 2s
🟡 Warning	Amber	Performance issues > 2s
🔴 Critical	Red	System failures detected

🛡️ Security Features

✅ Server-side Sessions - No sensitive data in browser cookies
✅ Role-Based Access Control - User, Analyst, Manager, Admin roles
✅ Audit Logging - Complete authentication event tracking
✅ Session Security - Automatic timeout and secure headers
✅ Route Protection - Dashboard requires authentication
✅ HTTPS Enforcement - Secure production deployment

📊 Batch Processing

Batch Sizes: 50, 100, 500 records
Duplicate Prevention: Automatically skips existing records
Multi-dataset: Sanctions, PEPs, Debarment lists
Progress Tracking: Real-time feedback on loaded/skipped counts

📖 Detailed Documentation: See docs/OPENSANCTIONS_INTEGRATION.md for complete integration guide

🚀 Quick Start

📦 1. Clone & Setup

git clone https://github.com/paihari/aml-controller.git
cd aml-controller
pip install -r requirements.txt

⚙️ 2. Environment Configuration

# Create .env file with Supabase configuration (optional for cloud features)
cat > .env << 'EOF'
# Supabase Configuration (for cloud AML database)
SUPABASE_URL=https://your-project.supabase.co
SUPABASE_ANON_KEY=your-anon-key-here
USE_SUPABASE_FOR_SANCTIONS=true

# Database Configuration
LOCAL_DB_PATH=aml_data.db
EOF

🔍 3. Run Locally

# Start the dynamic AML system
python app.py

# System will automatically:
# ✅ Initialize cloud/local database
# ✅ Load live sanctions data (1.2M+ records if Supabase configured)
# ✅ Generate test transactions (stored in Supabase as PENDING)
# ✅ Start AML processing engine with transaction workflow
# ✅ Launch web dashboard with live data

🌐 4. Access Dashboard

# Dashboard available at:
http://localhost:5000/dashboard/dynamic.html

# API endpoints:
http://localhost:5000/api/health
http://localhost:5000/api/statistics
http://localhost:5000/api/alerts

# Note: If using Docker, the app runs on port 5001:
http://localhost:5001/dashboard/dynamic.html

🎯 Processing Steps

Generate Sample Data - Creates realistic transactions with PENDING status
Process Pending Transactions - Runs all AML detection rules
Risk Assessment - Determines transaction outcome:
- COMPLETED - Low risk, normal transaction flow
- UNDER_REVIEW - High risk, requires investigation
Alert Generation - Creates alerts for UNDER_REVIEW transactions with evidence

🚨 Alert Types Generated

Alert Code	Description	Risk Score	Trigger
R1_SANCTIONS_MATCH	Sanctions screening hit	95%	Name matches OFAC/UN lists
R3_HIGH_RISK_CORRIDOR	High-risk geography	85%	Transactions to/from sanctioned countries

        # Try Supabase first
        if self.use_supabase and self.supabase_db:

        sanctions_matches = self.local_db.get_sanctions_by_name(name)
        return self._process_matches(sanctions_matches)

🚀 Render Deployment Configuration

To enable the full Supabase integration on Render:

Step 1: Access Render Dashboard

Go to dashboard.render.com
Find your aml-controller service
Navigate to Environment settings

Step 2: Add Environment Variables

# Add these exact variables in Render dashboard:
SUPABASE_URL=https://skfyzufwzjiixgiyfgtt.supabase.co
SUPABASE_ANON_KEY=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJzdXBhYmFzZSIsInJlZiI6InNrZnl6dWZ3emppaXhnaXlmZ3R0Iiwicm9sZSI6ImFub24iLCJpYXQiOjE3NTU3MTY4MDcsImV4cCI6MjA3MTI5MjgwN30.4nfQwci8X7gScJTeYSPp5FejV7lPGZBFqvJ2G2tdTAY
USE_SUPABASE_FOR_SANCTIONS=true

Step 3: Verify Deployment

# Check statistics (should show 1,373+ records instead of 5)
curl "https://aml-controller.onrender.com/api/statistics"

# Test sanctions search (should find real data)
curl "https://aml-controller.onrender.com/api/sanctions/search?name=Kim Jong"

📈 Data Scale Comparison

Dataset	Current (Sample)	Available (Full)	Source
Debarment	765 records	~204,000 records	OpenSanctions Daily
PEPs	128 records	~989,000 records	OpenSanctions Daily
Total	1,373 records	1.2M+ records	Real sanctions data

🔄 Data Loading Process

# Load full datasets (when environment is configured)
curl -X POST "https://aml-controller.onrender.com/api/sanctions/refresh"

# This will automatically:
# ✅ Download latest OpenSanctions daily datasets
# ✅ Process 1.2M+ sanctions records  
# ✅ Store in Supabase with proper indexing
# ✅ Enable real-time sanctions screening
