AI-Driven Real-Time Fraud Detection System for Digital Banking Platforms

As a digital banking platform experiences rapid growth in transaction volume across account management, payments, lending, and cryptocurrency trading, it faces increasing risks from sophisticated cyber threats such as identity theft, account takeovers, and payment scams. Legacy rule-based fraud detection systems struggle to detect emerging fraud patterns in real-time, risking financial losses, regulatory non-compliance, and erosion of customer trust. The platform also must adhere to stringent AML and KYC regulations, requiring automated, compliant verification processes that integrate seamlessly into operational workflows.
