Short message identification method, device, terminal, server and non-transitory computer-readable storage medium

Abstract

The invention discloses a short message identification method and device, belonging to the field of information technology. The method comprises: obtaining geographical location information and time information of the short message to be identified; obtaining the recognition probability corresponding to the short message to be identified based on the space-time probability relationship and the geographical location information and time information of the short message to be identified, and the space-time probability relationship is based on the geographical location of the malicious text message Obtaining information and time information refers to the relationship between geographical location information, time information and identification probability, and the identification probability refers to the probability of being a malicious text message; based on the identification probability corresponding to the text message to be identified, it is identified whether the text message to be identified is a malicious text message, Malicious text messages refer to text messages from fake base stations. The present invention obtains the recognition probability corresponding to the short message to be recognized based on the space-time probability relationship and the geographic location information and time information of the short message to be recognized, so that the recognition process is more accurate and reliable.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a short message identification method and device. Background technique [0002] With the development of information technology, communication between users has become quick and convenient. However, illegal activities such as mass sending of malicious text messages through fake base stations are also becoming more and more rampant. Pseudo base stations are generally composed of a host computer and a laptop computer, which can search for nearby terminals and send short messages to nearby terminals by disguising themselves as the operator's base station. Since the short messages from the fake base stations usually contain malicious information such as fraud and marketing, the short messages from the fake base stations are often regarded as malicious short messages, and the method of identifying the malicious short messages has also attracted much attention. [0003] Based on ...

AI Technical Summary

Problems solved by technology

[0005] The content of malicious text messages can easily avoid sensitive words through pinyin, synonyms, etc., and criminals can also set the parameters of fake base stations to the parameters of normal base stations, so that the terminal cannot recognize malicious text messages. Therefore, the above method of text message identification is accurate Poor performance, low reliability
