摘要

E-commerce allows for the global buying and selling of goods and services, offering convenience and accessibility to consumers and businesses. However, it is vulnerable to fraud, with malicious transactions posing significant risks. Existing methods do not address changes in user behaviour over time for effective fraud detection. Therefore, this paper proposes a fraud detection method using FSMNN and considers dynamic user behaviour. Firstly, data is collected from the Fraudulent E-commerce Transactions dataset and pre-processed. KDA-BMOT is then used for data balancing. Next, categorical features are extracted and one-hot encoded, followed by outlier detection and removal using ELIPOF for numerical and encoded data. Data is then standardized using log transformation, aggregated temporally using RG-TCMM, and a transaction graph is built using an Adjacency List Graph (ALG). Change points are detected using the Cumulative Quantile Control Chart (CQCC) from the graph data and temporal aggregation. Features are extracted from the aggregated outcome, transaction graph, and detected change points. The FSMNN classifier is employed with transfer learning to detect fraud and normal transactions stored on the cloud. In real-time, IoT devices collect transaction details, which are stored in the cloud, analyzed for fraud detection, and updated accordingly. The proposed FSMNN detected the fraud transactions effectively with an accuracy of 97.58% and an F1-score of 98.95%, respectively.
