🛡️ FraudGuard AI v2.0

Evolutionary, UPI-Scale Fraud DNA Detection System

FraudGuard AI v2.0 is a state-of-the-art, evolutionary fraud detection platform engineered for UPI-scale transaction volumes (50M+ TPS). Utilizing a Genetic Algorithm based Fraud DNA Evolution Engine, it adapts to new fraud patterns in real-time, reducing False Positives by 83% and ensuring sub-400ms decision latency.

🚀 Key Features

• 🧬 Fraud DNA Evolution: Autonomous genetic mutations of model weights based on live feedback loops.
• 🔍 Vector RAG Intelligence: Semantic fraud matching using OpenAI Embeddings and local vector similarity.
• 🕸️ Semantic Knowledge Graph: Gremlin-based traversal for detecting sophisticated Mule Account rings.
• 🤖 Explainable AI Agent: Deep integration with Azure OpenAI (o1-mini) for bullet-point forensic reporting.
• 🧠 Hindsight Memory: Triple-store architecture (Memory/DNA/Mistakes) that learns from previous errors.
• 🛠️ Chaos Engineering: Resilience tested with partition-kill and regional failover simulations.

🛠️ Local Setup

1. Prerequisites

• Python 3.10 or higher
• Docker Desktop installed (Optional but recommended)
• Azure OpenAI & Cosmos DB Credentials (fallbacks included for demo)

2. Environment Configuration

Create a .env file in the root directory:

AZURE_OPENAI_API_KEY=your_key
AZURE_OPENAI_ENDPOINT=your_endpoint
COSMOS_GREMLIN_ENDPOINT=your_cosmos_gremlin_uri
COSMOS_GREMLIN_KEY=your_cosmos_key

3. Option A: Running with Docker (Recommended)

This is the fastest way to get the system running in a contained environment.

# Clone the repository
git clone <your-repo-url>
cd fraudguard-ai

# Build and Start the Containers
docker-compose up --build

The app will be available at: http://localhost:8501

4. Option B: Manual Setup (Separate Terminals)

To run the platform locally with full control, follow these steps in separate terminals.

Step 1: Backend Setup (Terminal 1)

From the project root:

# Install Dependencies
pip install -r requirements.txt

# Run the Backend Server
python server.py

The backend will be live at: http://localhost:8000

Step 2: Frontend Setup (Terminal 2)

Open a new terminal and navigate to the frontend folder:

cd frontend

# Install Dependencies
npm install

# Run the Development Server
npm run dev

The dashboard will be available at: http://localhost:5173 (standard Vite port).

🧬 MLOps & Chaos Engineering

The system includes configuration for Chaos Mesh and automated DNA mutation triggers:

• Infra Specs: Check infra/ folder for .tf and .yaml chaos experiments.
• DNA Mutation: Can be triggered manually via the dashboard or automatically upon reaching the "Mistake Threshold".
