Abstract

The embodiment of the invention discloses a batch risk case identification method and device and an electronic device. The method comprises: acquiring original event data corresponding to multiple risk cases; processing the original event data of the plurality of risk cases to obtain target event data of the plurality of risk cases, the target event data comprising a preset variable for describingcommitting features; clustering the target event data of the plurality of risk cases based on a density clustering algorithm to obtain clustering results of the plurality of risk cases; and identifying batch risk cases based on the clustering result.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a batch risk case identification method, device and electronic equipment. Background technique [0002] Risk cases refer to events (such as stolen accounts) or a collection of events that occur through service-providing platforms (such as third-party payment platforms) that will bring risks to platform users. Risk cases are an important basis for adjusting the platform's risk control model and risk control strategy to carry out risk prevention and control in a timely manner. In the case analysis process of a platform, it is one of the important means to speed up the speed of risk prevention and control by timely identifying batch risk cases caused by criminals committing crimes in batches from many cases. Taking the third-party payment platform as an example, criminals may commit crimes in batches by breaking through specific verification methods and selling stolen g...
