"Black card" identification method, electronic device and computer-readable storage medium

Abstract

Embodiments of the present application provide a "black card" identification method, electronic equipment, and a computer-readable storage medium. Using the scheme in this application, the original data is obtained, and the original data is processed to form identification data uniquely identified by the phone number; anomaly detection is performed on the identification data to determine the abnormal label of each phone number; the abnormal label After adding the identification data identified by the corresponding phone number, construct an undirected graph based on the identification data added to the abnormal label; identify whether each phone number is a "black card" according to the undirected graph. This solution forms the identification data uniquely identified by the phone number, and performs anomaly detection on the identification data. After determining the abnormal label of each phone number, the abnormal label will be added to the identification data identified by the corresponding phone number. The identification data constructs an undirected graph, and identifies whether each phone number is a "black card" according to the undirected graph, and realizes the accurate identification of the "black card".

Description

technical field [0001] The present application relates to information security technology, in particular, to a "black card" identification method, electronic equipment, and a computer-readable storage medium. Background technique [0002] Phone "black card" refers to a mobile phone card that has not registered or embezzled the identity information of others, and may be used by criminals to commit illegal and criminal activities. Although various operators have strengthened the real-name system, criminals can still obtain "real-name system" phone cards, and these cards have nothing to do with the criminals' own identity information, thus providing great convenience and concealment for their illegal activities . Some of these "black cards" are sold at high prices, and some are used to hoard a large number of criminals in the hands of criminals for the purpose of "sweeping wool", that is, raising cards. For example, the "first order discount" activities on some platforms, new...

AI Technical Summary

Problems solved by technology

[0004] This method needs to manually summarize the "black card" recognition rules and thresholds based on the sample data, lacks self-adaptive capabilities, and needs to constantly summarize new recognition rules and thresholds to prevent the recognition rules from being avoided
