Problems solved by technology

In order to minimize the impact of Concept drift, the classifier used in the existing FDS system takes a lot of time to analyze a large number of user behaviors, including normal behaviors and fraudulent behaviors, making it difficult to meet the requirements of real-time detection. Requirements, and because illegal acts of financial fraud are often relatively short-lived, real-time detection is one of the important criteria for testing the practicability of an efficient FDS system

Abstract

An embodiment of the invention discloses a financial fraud identification method which is used for solving a problem that an existing FDS reduces a Concept drift influence and simultaneously is difficult to satisfy an instant detecting requirement. The method comprises the following steps of acquiring current transaction behavior data of a target user; and inputting the current transaction behavior data into a ground floor classifier and acquiring a determination result output by the ground floor classifier. The embodiment of the invention also provides a financial fraud identification system.

Description

technical field [0001] The invention relates to the field of financial services, in particular to a method and system for identifying financial fraud. Background technique [0002] The FDS system (Fraud detection system, financial fraud identification system) plays an important role in the Internet financial transaction process. It judges whether the user's current behavior is abnormal by analyzing the user's financial transaction behavior through big data, so as to determine the current Whether there is financial fraud in financial transactions. [0003] At present, the development of the FDS system is facing many challenges. Among them, normal users or scammers always change their consumption behavior from time to time (Concept drift) and support real-time detection (Supports real time detection) are more important technologies difficulty. In order to minimize the impact of Concept drift, the classifier used in the existing FDS system takes a lot of time to analyze a lar...
