Embodiment 1

[0064] This embodiment discloses a method for identifying abnormal transactions based on a capital transaction network. The identification of abnormal transactions (including money laundering risks) in the present invention is based on bank customer data, account data, and various transaction records, such as figure 1 As shown, the abnormal transaction identification method includes the following steps.

[0065] Step S1, obtain the bank's transaction-related data, and standardize the acquired transaction-related data, so as to convert the transaction-related data into multiple types of subject data, such as converting the data of the credit system, the national knot system, and the core system into the same subject Standards, build a data mart through multiple types of subject data, which is used as the basis for identifying abnormal transactions; in this embodiment, multiple types of subject data include customer subject data, account subject data, and transaction subject data...

Embodiment 2

[0082] Such as Figure 5 As shown, based on the same inventive concept as Embodiment 1, this embodiment provides an abnormal transaction identification system based on a capital transaction network for implementing the abnormal transaction identification method of Embodiment 1. The abnormal transaction identification system includes: data The market construction module, basic index mining module, risk feature generation module, transaction network construction module, suspicious case generation module, screening report generation module and risk model establishment module are described in detail in this embodiment as follows.

[0083] The data mart building module is used to standardize the acquired transaction-related data, so as to convert the transaction-related data into multi-category subject data, and to construct a data mart through multi-category subject data.

[0084] The basic index mining module is used to process multiple types of subject data in the data mart thro...

Abstract

The invention discloses an abnormal transaction identification method and system based on a capital transaction network. The abnormal transaction identification method includes the following steps: a step of constructing a data mart through multiple types of subject data, a step of determining basic index data, and generating a first risk The steps of characteristic data, the steps of establishing multiple capital transaction networks based on transaction data, the steps of generating suspicious cases of abnormal transactions, and the steps of generating suspicious screening reports; the abnormal transaction identification system includes: data mart building modules, basic index mining module, risk feature generation module, transaction network building module, suspicious case generation module and screening report generation module. Based on the established capital transaction network and transaction risk model, the present invention can completely restore the money laundering process and money laundering scene, and provide strong support and assistance for the investigation of money laundering; the present invention also has high precision, good comprehensiveness, and strong objectivity and other outstanding advantages.

Description

technical field [0001] The present invention relates to the technical field of transaction data processing, and more specifically, the present invention relates to a method and system for identifying abnormal transactions based on a capital transaction network. Background technique [0002] Anti-money laundering often refers to the prevention of the source and nature of the proceeds of crimes such as concealing and concealing drug crimes, gangland-like organized crimes, terrorist crimes, smuggling crimes, corruption and bribery crimes, and crimes that disrupt financial management order.
