Credit Card Transaction Fraud Detection Based on Graph Analysis Algorithm
Currently,online credit card transaction fraud cases are rapidly increasing,with more diverse methods and tactics being used.The credit card transaction fraud detection has become the key focus of bank risk prevention and control.This paper relies on the popular graph analysis theory and algorithms in the field of Artificial Intelligence in recent years.It transforms credit card transaction data into graph-structured data to analyze the community information of the credit card transaction fraud graph.Based on this,it applies the graph representation learning algorithm Deepwalk and Machine Learning classifiers,and a credit card transaction fraud detection model is constructed to predict fraudulent behavior.The experiment results show that the model detection accuracy for fraud behavior reaches 70%.
