Embodiment Construction

[0077] The embodiment of the present invention provides a method, device, device, and storage medium for identifying gangsters, by extracting the characteristics of multiple nodes in the request information after receiving the request information sent by the same user account within the preset time range ; Based on the characteristics of each node, construct the risk feature map of the user account, and divide the risk feature map into multiple feature subgraphs; use the preset coding measurement algorithm to calculate the shortest code length of each feature subgraph, and according to the shortest code length Each feature subgraph is split into multiple feature communities; each feature community is input into the preset black gang identification module to determine whether the user account is a black gang. The invention realizes the real-time identification of black industry gangs, and improves the defense ability of black industry gangs.

Abstract

The invention relates to the field of big data and discloses a black product gang identification method, device and equipment and a storage medium. The method comprises the following steps of within apreset time range, after receiving request information sent by the same user account each time, extracting a plurality of node features in the request information; based on each node feature, constructing a risk feature graph of the user account, and segmenting the risk feature graph into a plurality of feature sub-graphs; respectively calculating the shortest coding length of each feature sub-graph by adopting a preset coding measurement algorithm, and respectively splitting each feature sub-graph into a plurality of feature communities according to the shortest coding length; and inputtingeach characteristic community into a preset black product gang identification model for identification, and outputting a black product gang identification result. The invention also relates to a blockchain technology, and the request information is stored in the blockchain. According to the method, real-time identification of the black gang is realized, and the defense capability of the black gangis improved.

Description

technical field [0001] The present invention relates to the field of big data, in particular to a method, device, equipment and storage medium for identifying gangs in black production. Background technique [0002] Network illegal production refers to the use of network technology, some illegal technical means such as counterfeit devices, LBS (Location Based Services, location-based services), frequent IP changes, etc. to bypass the risk control strategy, thereby exploiting platform rule loopholes or A criminal organization that obtains benefits within the scope of the gang. Black production gangs are generally affected by resource and task constraints, and have the characteristics of aggregation, short-term high frequency and so on. And with the progress of security confrontation, the black industry of online fraud has shown the characteristics of an industrial chain. Around fraud, a professional technology development industry, identity credit packaging and false identit...
