Problems solved by technology

[0004] 1) Manually add, this method is cumbersome to operate, and may not be able to fully cover blacklist numbers;
[0005] 2) Based on the frequency of sending the calling number, this method is easy to wrongly pull some numbers of mass notifications into the blacklist, and the error rate is high

example 1

[0080] Example 1: If a calling number sends 15 text messages to 5 called numbers in total, and each called number receives 3 text messages, the times of sending are as follows:

[0081] {3,3,3,3,3}

[0082] Then the distribution probability of each called number is as follows:

[0083] {0.2,0.2,0.2,0.2,0.2}

[0084] Therefore, the calculated called information entropy of the calling number is 1, indicating that the called number distribution of the calling number has a high degree of dispersion and a low degree of concentration.

example 2

[0085] Example 2: If a calling number sends 15 text messages to 5 called numbers in total, 1 text message is sent to each of 4 called numbers, and 11 text messages are sent to 1 called number, The number of times it is sent is as follows:

[0086] {1,1,1,1,11}

[0087] Then the distribution probability of each called number is as follows:

[0088] {0.067,0.067,0.067,0.067,0.733}

[0089] The calculated called information entropy of the calling number is 0.59, indicating that the distribution of called numbers of the calling number has a small degree of dispersion and a high degree of concentration.

[0090] According to the calculation of the above information entropy, the scheme of the present invention performs data mining on the historical records of short messages within a certain period of time. When the frequency of sending short messages by a certain calling number exceeds a certain threshold, the calling number is calculated according to the above formula (1). The c...

Abstract

The invention discloses an information interception method, device and storage medium. The method comprises: acquiring the historical record of the information sent by the calling number; obtaining the frequency of the information sent by the calling number according to the historical record of the information sent by the calling number; The frequency of information sent by the number is calculated to obtain the information entropy of the called number of the calling number; when the information entropy of the called number of the calling number is greater than the preset threshold, the calling number is determined to be the number sending spam, and the calling number is added to the to the calling number blacklist. The invention is easy to operate, greatly reduces the cumbersomeness of manually judging and adding the blacklist, and also greatly improves the accuracy of the blacklist, reduces the false blocking rate of spam short messages, and improves the processing efficiency of the short message filtering system.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an information interception method, device and storage medium based on the information entropy of a called number. Background technique [0002] With the development of domestic communication services, short message services are more and more widely used. More and more people use short messages as a convenient communication method to communicate with each other. But, along with the expansion of short message application field, a large amount of unscrupulous merchants also send advertisement and fraudulent information by means of this platform of short message, the user has to receive some short messages that are not willing to receive. Along with the flooding of spam messages, many spam message interception systems have also been born to filter these spam messages. A very important part of spam interception is the filtering of blacklist numbers. As long as it is ju...
