SecureCredit - AI-Powered Financial Security for Africa

Inspiration

With 66% of Africa's population remaining unbanked while mobile money adoption exceeds 50% in countries like Kenya and Ghana, I recognised the urgent need for intelligent security solutions tailored to Africa's unique financial landscape. SecureCredit bridges this gap by providing AI-powered fraud detection and credit scoring for mobile money ecosystems.

What it does

SecureCredit is a working prototype that demonstrates AI-powered fraud detection and credit scoring capabilities for Africa's mobile financial services, with a focus on practical implementation over ambitious scale.

Core Features (Implemented)

Fraud Detection Engine

  • Rule-based transaction analysis with real-time risk scoring
  • Single transaction testing with immediate fraud assessment
  • CSV bulk processing for batch analysis
  • Interactive dashboard with live monitoring capabilities

Credit Scoring System

  • CRUD operations for credit profile management
  • Alternative data analysis using mobile money patterns
  • Risk categorisation (Low/Medium/High) with scoring rationale
  • PDF/CSV report generation

Device Security

  • Real-time device fingerprinting using @fingerprintjs
  • Trust score monitoring with 5-second updates
  • Device history tracking and behavioural pattern analysis
  • Geographic risk assessment

Mobile-First Design
