Method and system for monitoring and filtering garbage short message transmitted by short message gateway

Abstract

The invention relates to a monitoring and filtering method and a system for utilizing an internet short message gateway to send spam messages. The method comprises the following steps: step 1, the content pre-treatment of key words is carried out; step 2, the content pre-treatment of the contents of short messages is carried out; step 3, after being carried out the content pre-treatment, the key words and the contents of the short messages are matched with each other, and the statistics of the matched sum of weighted values is carried out; step 4, the short messages with the sum of the weighted values which is in line with the preset conditions are filtered. The method can overcome the interference of the anti-filtering technology, improve the filtering success rate of the spam messages, solve the problem of carrying out the wrong filtering of the normal short messages and improve the accuracy of the judgment on the filtering of the short messages with the sending number.

Description

technical field [0001] The invention relates to spam short messages, in particular to a method and system for monitoring and filtering spam short messages sent by a short message gateway. Background technique [0002] As mobile operators launch enterprise-oriented industry SMS applications, more and more enterprise users begin to use industry SMS services, bringing considerable economic effects to operators. However, in the process of business development, there are also some criminals and bad service providers (SPs), who take advantage of the characteristics of this business to quickly send a large number of short messages, and send a large number of illegal messages, causing adverse social impact and causing user complaints. Therefore, these spam messages must be monitored and filtered. [0003] In the existing short message center-oriented spam filtering method, there are mainly two mechanisms to realize the monitoring and filtering of short messages: content keyword fil...

Problems solved by technology

[0004] The content (keyword) in the traditional content keyword filtering mechanism is mainly realized by manual addition, and automatic addition cannot be realized yet. The advantage of this filtering mechanism is that its principle and implementation method are relatively simple, and the application cost is low

However, this mechanism has some major limitations: first, it is very difficult to select keywords, and it is difficult to judge the legitimacy of the text message content only through keyword matching, and illegal text messages are often missed; second, it is easy for criminals to use various methods Bypassing the keyword list, for this type of SMS, the keyword filtering mechanism is useless; the third is that the misjudgment is serious, and normal SMS are often filtered out

This filtering method is not suitable for SMS filtering on the SMS gateway, because the enterprise uses a single access number when accessing the SMS gateway, and its own traffic has dozens to hundreds of SMS messages per second

[0014] Above-mentioned two kinds of commonly used filtering mechanisms are all difficult to be applicable to the spam short message filtering on the short message gateway, and the characteristic of this kind of short message is, the short message that the user uses computer system to connect to the short message gateway to send has fast speed originally, and quantity is many, and content dynamic changes more. Convenience, easy to implement anti-filtering transformation
