Predominately, there are two kinds of solutions in the market for fraud detection and prevention 1) Based on rule engine 2) based on AI. Its not possible to support the instant decision making by using the AI engine, since it can’t handle the real time data directly. For instant decision making, rule engines are used universally. For credit card or debit card transaction where response time is 8 to 10 second, such solutions are ideal. Though its possible to use combination of both to make more efficient and accurate prediction. We will discuss in this article different popular rule engine available in the market and combination of AI and rules solutions. There are five popular rule engines in the market:
