Abstract

A method and apparatus for trainning a fraud detection model and a method and apparatus for fraud detection are provided, includes acquiring target history operation behavior information of a plurality of sample users at a sampling time when the target history operation behavior occurs and in a preset history period before the sampling time, and label information indicating whether or not a fraudbehavior occurs at the sampling time for each sample user, and obtaining the target history operation behavior information of the sample users at the sampling time. According to the acquired historical operation behavior information of the target, the behavior feature vector sequence and the time interval sequence under each operation type are generated. Based on the sample user's behavior eigenvector sequence, time interval sequence and label information, the fraud detection model is trained to obtain the fraud detection model. The present application can analyze the current target operationbehavior of the user when using the electronic bank according to the target historical operation behavior and the current time target operation behavior, and improve the accuracy of judging whether the current target operation behavior of the user is a fraudulent behavior or not.

Description

technical field [0001] The present application relates to the field of computer information technology, in particular, to a fraud detection model training method and device, and a fraud detection method and device. Background technique [0002] Electronic banking refers to the communication channels that banks open to the public. With the rapid development of the Internet and the popularity of smart terminals, e-banking is a commonly used banking business processing method in e-commerce activities, such as: using e-banking for online transfers, checking account balances, online financial management and other out-of-the-counter services, and Handling business outside the cabinet provides great convenience for users. However, while electronic banking provides convenience for users, there are also many potential safety hazards, such as: account information theft, account information embezzlement, and abnormal operation behaviors such as stolen funds, which damage the interests...
