Method and device for determining and blocking spam by malicious user

Abstract

The present invention relates to the field of converged communications, and in particular to a method and a device for determining and blocking spam by a malicious user. A user terminal sends a reportrequest for spam to a server, and the server analyzes and processes the report request, calculates the credit value of each report user separately, and separately calculates the malicious level of each reported user, and determines a malicious user and a suspected malicious user from the reported users; and when receiving an information sending request sent by the user terminal, performing corresponding processing, according to the determined malicious user and the suspected malicious user, on the information sending request sent by the user terminal. In this way, the credit value of the report user and various factors are comprehensively considered, and the reported user is subjected to malicious level evaluation; thus, the determined malicious user is more accurate and reliable; furthermore, the spam can be effectively and reliably blocked according to the determined malicious user and the suspected malicious user, and the scope of application is relatively wide.

Description

technical field [0001] The invention relates to the field of converged communication, in particular to a method and device for malicious users to determine and block junk information. Background technique [0002] With the continuous development of communication services, at present, a large number of spam calls, spam text messages, spam emails, spam information or other information have a great impact and interference on users. [0003] For example, in the prior art, there are mainly two methods for preventing spam calls: 1) Deploy a called trap network in the communication network, collect suspicious voice information, extract characteristic behaviors from the collected information, and send characteristic behavior data To the central server, the central server analyzes the characteristic samples in each called trap network, obtains the probability that the calling terminal initiates a spam call, and filters out the calling request of the terminal according to the initiati...
