Short message intercepting method and device and cloud server

Abstract

The invention provides a short message intercepting method and device and a cloud server. The short message intercepting method comprises the steps that short messages uploaded by the short message intercepting device are received; word segmentation processing is conducted on text content of the short messages, and key words of the text content are obtained; first probability weighted values of all the key words belonging to junk short messages and second probability weighted values of all the key words belonging to normal short messages are obtained; a first joint probability of all the first probability weighted values of the key words and a second joint probability of all the second probability weighted values of the key words are obtained; whether the short messages are junk short messages or not is determined according to the first joint probability and the second joint probability; informing information is sent to the short message intercepting device, wherein the informing information comprises the information for judging whether the short messages belong to information of junk short messages or not so that the short message intercepting device can determine whether to intercept the short messages currently received or not according to the informing information. The short message intercepting method can solve the problems that in the prior art, the junk short message recognition rate and intercepting efficiency are low, and cost is high.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a short message interception method and device, and a cloud server. Background technique [0002] With the development of mobile communication services, the popularization of mobile phones and the decline of the charges for short messages, more and more users use short messages to transmit information. However, users receive more and more spam messages such as advertising messages and scam messages, and the spam messages are becoming more and more flooded, which has seriously affected the user's experience of using the message, which has exceeded the user's tolerance. It is urgent to deal with spam text messages. [0003] At present, spam SMS management mainly adopts automatic filtering and manual filtering. There are three main ways to intercept spam text messages: (1) Automatically filter users who meet the conditions through keywords and enter the blacklist; (2) Text ...
