Financial fraud detection framework

This innovation is an AI-based system that helps banks and mobile money providers in Africa spot suspicious transactions linked to money laundering and fraud. Current monitoring tools rely on fixed rules, such as flagging any large transfer. These rules raise many false alarms, waste investigators' time and miss new patterns as customer behaviour changes. The system solves this in two ways. First, it learns normal account behaviour, such as how balances change, and flags transactions that don't fit. Second, it automatically adjusts how many alerts it raises when transaction patterns shift. In tests on over one million transactions, it nearly doubled detection quality compared with a rule-based approach and cut false alarms. The adaptive feature cut alerts by a further 25%, though it caught slightly fewer suspicious cases. The result could be faster, more focused investigations, lower compliance costs and greater trust in digital financial services. Working alongside existing regulations and human investigators, it can strengthen financial governance and support safe financial inclusion across Africa.
