System and method for realizing intelligent early warning of fraudulent transactions

Abstract

The invention relates to a system and a method for realizing intelligent early warning of fraudulent transactions, the system comprises a protocol processing layer, a capability opening layer, a security control layer, a scene combination layer, an operation management layer and a network management layer, and the method comprises the following steps: fusing multi-source heterogeneous data; performing complex multi-source behavior feature modeling based on deep learning; performing anti-fraud intelligent identification based on incremental learning; constructing and analyzing a fraud behaviorobject association network map based on deep learning of the graph structure; constructing and reasoning an anti-fraud rule knowledge graph; performing decision engine construction. The technical problems that linkage between data sources of an existing anti-fraud transaction technology model is insufficient, and the fraud rule feature networked optimization requirement cannot be met can be solved.

Description

technical field [0001] The invention relates to the application field of financial anti-fraud big data, in particular to a system and method for realizing intelligent early warning of fraudulent transactions. Background technique [0002] In the current financial anti-fraud application field, the existing anti-fraud technology model is based on the lack of linkage between data sources and the characteristics of fraud rules do not meet network optimization, and cannot meet the authority, efficiency, real-time and other issues of verification requirements, often It will lead to the inability to efficiently identify and effectively suppress the occurrence of fraudulent transactions before and during the transaction. Therefore, the current verification method still has technical problems and cannot meet the above requirements. [0003] Aiming at the problems in the related technologies, no effective solution has been proposed yet. Contents of the invention [0004] Aiming at...
