dc.description.abstract | The rapid development and popularization of the e-commerce business in the past few decades have made online purchasing of products preferable and more comfortable shopping method for buyers. As credit / debit cards became most common payment method for both online and regular purchases, the number of registered fraudulent transactions also increased significantly. Fraudsters seem to find back-doors in the security systems, leading to accumulation of losses for banks, merchants and customers. Therefore implementation of efficient fraud detection system has been made imperative for bank issuing systems in order to be able to predict suspicious behavior and stop fraud before it occurs. Modern techniques for fraud prevention include Machine Learning, Data Mining, use of Artificial Immune Systems etc. Based on the dataset and the present information various techniques could be used to develop security systems. This project has a goal to examine the transaction process for both genuine and fraudulent purchases of online products and using a Naive Bayes algorithm to be able to detect an flag the suspicious such. The algorithms selection is based on the dataset size (small dataset, since credit card details include sensitive data) and due to the high probability performance of Naive Bayes when data is not clustered or is partially missing. | en_GB |
