The Efficacy of Artificial Intelligence in Financial Fraud Detection: A Transition from Rule-Based to Machine Learning Systems
0 viewsAbstract
As digital financial transactions proliferate globally, the frequency and complexity of fraudulent activities—such as credit card fraud, identity theft, and online scams—have escalated significantly, resulting in billions of dollars in annual losses. Traditional, rule-based fraud detection systems are increasingly inadequate, constrained by static parameters and high false- positive rates that disrupt customer experience and increase operational costs. This study evaluates the efficacy of Artificial Intelligence (AI) and Machine Learning (ML) as superior alternatives for modern financial fraud detection and prevention. Utilizing a qualitative, descriptive methodology based on a comprehensive review of academic literature and industry case studies, this research examines the mechanics, benefits, and implementation challenges of AI-based systems. The findings confirm the study’s hypothesis: ML algorithms—specifically neural networks and decision trees—drastically improve detection accuracy by analyzing vast, complex datasets in real- time, identifying hidden behavioral anomalies, and continuously adapting to novel fraud strategies. Furthermore, AI significantly reduces false positives, thereby minimizing financial losses and preserving customer trust. However, the study also highlights critical implementation barriers, including the necessity for high-quality training data, advanced technological infrastructure, and stringent data privacy compliance. Ultimately, this research concludes that AI is an indispensable, dynamic tool in contemporary financial security, offering unparalleled advantages over legacy systems in the ongoing fight against digital financial crime.
