Abstract :
Fraud that involves cell phones, insurance claims, tax return claims, credit card transactions, government procurement etc. represent significant problems for governments and businesses. Technology advances have brought along new opportunities and security challenges. Fraud in a world of advanced technologies, which is one of the greatest challenges for businesses and organizations, now takes new and unconventional dimensions that are more difficult to detect than its traditional forms. Due to the dramatic increase in fraud which has cost businesses billions of dollars each year, several modern fraud detection techniques are continually evolving to meet the unprecedented challenge. Data mining (DM) is the most recognized and effective technology that has been deployed for fraud detection. This study looks at the concept of DM and current techniques used in detecting fraud and reviews DM methods used to detect fraudulent payment transactions. It explores some of the most effective DM techniques for detecting different types of fraud, categorizing them based on supervised and unsupervised methods. A model that can differentiate fraudulent transactions from genuine transactions based on a given dataset was proposed
