Description

Short message filtering method and system

Technical field

The embodiments of the present invention relate to the field of communications technologies, and in particular, to a short message filtering method and system.

Background technique

SMS communication is one of the main ways for people to communicate daily. While providing users with convenient communication methods, a large number of harassing text messages also bring confusion to users.

In the prior art, there are two implementation modes for the control of harassing short messages: mode 1: mainly through the spam short message monitoring system at the operator level, and its main function is to determine whether the sending behavior of the calling number within the unit time period is reached. The violation threshold determines whether the calling user belongs to the offending user, and then restricts or prohibits the calling user's short message sending function, which reduces the harassment behavior of the spam message to a certain extent. In the control method of the harassing short message, the monitoring rule consisting of the number of the calling number in the unit time and the dispersion of the called number is usually used to perform the calling behavior of the calling user within a certain period of time. Monitoring, the disadvantage of this method is that the anti-harassment function cannot be set according to the will of the receiving user.

Manner 2: The harassment message sent by the calling party is filtered by using the value-added service system of the operator and setting the blacklist of the calling number. This method is a passive way to shield and harass text messages. Users need to frequently set and update the numbers on the blacklist. Once the sender number of a harassing message is not on the blacklist, it will be sent to the fish. The receiver brings a bad experience to the receiver. Therefore, the interception of the harassment message in this way depends on the blacklist, and the uncertainty of the sender of the message appears to be powerless, and the user needs to frequently update the blacklist, and the user experience is poor. Therefore, how to improve the pertinence of harassment SMS interception, improve the accuracy of harassing SMS interception, and harass SMS interception according to the individual wishes of users are technical problems that need to be solved in the prior art.

detailed description

The embodiments of the present invention are further described in detail below with reference to the accompanying drawings.

Embodiment 1:

This embodiment provides a short message filtering method, including:

S101. Receive a short message to be determined sent by the short message center.

S102. Determine, according to a preset determining rule, whether the short message is a harassing short message, and the determining rule includes: determining whether the content of the short message satisfies the first determining condition of the preset short message content;

S103: Send the determination result to the short message center, and notify the user to filter the to-be-determined short message that is determined to be the harassing short message.

Considering that the content of the harassment message may include a word directly extracted from the short message content, and an analysis result obtained by semantic analysis according to the content of the short message, in order to make the accuracy of the judgment according to the content of the short message to be determined in the embodiment Preferably, in this embodiment, the method for determining whether the content of the short message to be determined satisfies the first determination condition of the preset short message content includes at least one of the following:

The first type: matching the content of the short message to be determined with the preset keyword of the suspected harassment message, and determining, according to the matching result, whether the content of the short message to be determined satisfies the preset condition of the short message content.

The second type: semantically analyzing the content of the determined short message, matching the analyzed semantics with the semantics of the preset suspected harassing short message, and determining, according to the matching result, whether the content of the determined short message satisfies the preset short message content determining condition.

The above two methods can be used together. For example, after the first method is used to determine that a short message belongs to a normal short message, the second method of the embodiment is used to perform semantic recognition and judgment on the short message that is determined to be a normal short message. Identify harassing text messages with a high degree of camouflage.

In the first method, the keyword suspected of harassing the short message may be a frequently used word summarized from a plurality of harassing short messages, such as "Happy Camp", "Very 6+1", "Winning", "Sold" Words such as "room" and "price reduction sales". Preferably, in this embodiment, these keywords can also be classified as corresponding to different doubts. Similar to harassing SMS type keywords, the types of suspected harassing SMS messages may include: real estate, commercial advertising, fraud, pornography, etc. The corresponding keywords can be set to various types of harassing text messages. word. For example, the keywords of real estate text messages may include words such as "sale of housing", "price reduction", "XX yuan/square meter", and keywords of commercial advertisements may include words such as "sale", "sale only", and "price reduction". word. The process of matching the content of the judgment message with the keyword of the presumed suspected harassment message is actually a process of determining whether a keyword suspected of harassing the message is present in the message to be determined, so the method for determining the keyword has a simple process. The advantages of easy implementation.

In the second method, the semantics of the preset suspected harassment message may be set by referring to the setting manner of the keyword of the suspected harassment message, and the semantic correspondence of the suspected harassment message is classified into different types of suspected harassing messages. When the analyzed semantics match the semantics of the default suspected harassment message, the same or similar semantics can be considered as a successful match. Using semantic analysis to analyze the content of harassing SMS messages is more complicated than the method of matching keywords in the first method. However, considering the harassment of text messages such as scams, it is more and more difficult to identify the words, and the second method can be used. Judging the content of the short message to conduct a comprehensive analysis, and obtaining relevant semantics, the analysis of the judged short message is more comprehensive and flexible, and the suspected harassment short message can be identified to a greater extent.

The above-mentioned judging method is based on the content of the short message, and the sender's number of the short message is used as a basis for judging the harassing short message. Preferably, the determining rule of the embodiment further includes the sender of the short message to be determined. Whether the number satisfies the second judgment condition of the preset number.

At the same time, considering that the content judgment method may be misjudged according to the above content judgment manner, in order to cope with the situation and improve the judgment accuracy of the embodiment, a white list of the calling number may be set, and the sender number belongs to the calling number white. The short message of the list is judged as a normal short message. Considering that the current short message masquerading is more advanced, in this embodiment, a blacklist of the calling number can be set, and the short message whose calling number belongs to the blacklist is determined as the harassing short message. Therefore, preferably, the second determining condition for determining whether the content of the short message to be determined satisfies the preset number comprises: determining whether the sender number of the short message is on the blacklist of the calling number, and/or determining whether the sender number of the short message is The calling number is on the white list.

In this embodiment, the whitelist of the calling number may be implemented by the user uploading his own address book, and the blacklist of the calling number may include the number set by the user and the abnormal transmission sent by the system side and recorded to the blacklist of the calling number. The party number, the abnormal sender number includes: the sender number whose message transmission behavior is abnormal.

The abnormal sending behavior here indicates that the frequency, time, etc. of the sender sending the short message does not satisfy the normal situation. According to the number of times the calling number sends the short message in the unit time, it can be judged whether the sender's behavior is abnormal, for example, when a certain calling party If the number of messages sent within one minute exceeds the preset threshold, the number can be sent. The sending behavior is judged as an abnormal sending behavior. At this time, the short message sent by the number may be a harassing short message; and the time may be further determined according to the time when the calling number is sent by the calling number, for example, a certain number is in a regular rest time in the early morning. The message is still being sent continuously, the sending behavior of the number is not a normal sending behavior, and the sent short message may be a harassing short message. Therefore, in this embodiment, the abnormal sending number is received and recorded in the blacklist of the calling number, so that the harassing short message can be more accurately determined.

Considering that over time, the user's address book and user-defined blacklist numbers will change, and the types of harassing text messages will increase, and the keywords or semantics of suspected harassing text messages will increase, and the original The judging rule may reduce the accuracy of the spoofing short message filtering. In order to meet the needs of the user, preferably, the embodiment may accept the modification of the judging rule by the user, and update the judging rule according to the modification of the user.

It can be understood that, in this embodiment, the determination rule can be stored and extracted and used when performing the harassment message filtering. Therefore, in this embodiment, the update determination rule is understood to replace the stored old judgment by using the modified judgment rule of the user. rule.

It is conceivable that, in this embodiment, the first determining condition and the second determining condition can be used together to implement the second-level judgment of whether the short message is to be harassed, and the present embodiment does not have any order for the second-level judgment. Limited, so the two levels of judgment methods have at least the following combinations:

Method 1: The first step is to match the sender number of the short message to be judged with the number on the white list of the calling number. If the matching is successful, the short message to be determined is a normal short message, and the next level of judgment is not required. If the match fails, the next level of judgment is made;

The first step may be that the sender number of the short message to be determined is matched with the number on the blacklist of the calling number, and if the matching is successful, the short message to be determined is a harassing short message, and the next level of judgment is not required. If the match fails, the next level of judgment is made;

The second step is to determine whether the content of the short message to be determined satisfies the first judgment condition of the preset short message content, and if yes, the short message to be determined is a harassing short message, if not, then not.

Method 2: The first step is to determine whether the content of the short message satisfies the first judgment condition of the preset short message content, and if so, the next level of judgment is performed, otherwise, the next level of judgment is not performed;

In the second step, the sender number of the short message to be determined is matched with the number of the calling number on the list. If the matching is successful, the short message to be determined is a normal short message. If the matching fails, the short message to be determined is a harassing short message.

The second step may be that the sender number of the short message to be determined is matched with the number on the blacklist of the calling number, and if the matching is successful, the short message to be determined is a harassing short message.

In this embodiment, determining whether the short message to be determined is a harassing short message according to a preset determination rule In addition to the above-mentioned short message content-based and number-based methods, the determination may be based on other information of the short message, for example, determining whether the short message to be determined is a harassing short message according to information such as the sending time of the short message, the sending location, and the attribution of the sender. .

In the above step S103, the short message center filters the harassment short message according to the received judgment result, that is, does not send the harassment short message to the receiver, and considering the above judgment, the erroneous short message may be harassed for the user. For the benefit consideration, the user needs to provide the function of querying the harassing short message. Preferably, the embodiment can store the harassing short message for subsequent query and use by the user.

When the user is viewing the harassment message, if the message is found to be a harassment message, the sender's number can be submitted to the system to record the blacklist of the calling number, which can achieve the purpose of not requiring the user to change the blacklist update.

In the embodiment, the first determination condition may be used to classify the types of the suspected spoofing short message. When the harassing short message of the embodiment is stored, the short message may be classified and stored according to the type of the harassing short message.

It is conceivable that the short message filtering method in this embodiment can be provided by the operator for the user, and the corresponding service can be referred to as a short message filtering service, and the service can be provided as a value-added service for the user, and the user can provide the information through the operator. The account registration or online registration is used to open the account. After the activation, the SMS of the registered user needs to be harassed by the SMS. Therefore, the SMS to be determined in this embodiment may also be the recipient of the SMS filtering service. User's text message.

Preferably, the user can perform the above-mentioned judgment rule update through the user-oriented interaction platform. For example, on the interactive platform, a custom decision rule can be entered or the judgment rule can be supplemented on the interactive platform, and the current address book can be synchronized to the system for use as a new whitelist of calling numbers. Considering the convenience of viewing the harassment message, the number of unread harassment messages can also be displayed on the interactive platform, prompting the user to view it in a centralized manner, and providing a possibility of saving for the misjudgment.

After determining the judgment result of the to-be-determined short message by using the second-level judging method of the above-mentioned harassment short message, the judgment result needs to be transmitted to the short message center, and the control short message center performs corresponding processing on the judgment short message according to the judgment result. It can be understood that there are only two kinds of judgment results in this embodiment, one is that the short message to be judged is a harassing short message, and the other is that the short message to be determined is a normal short message. The processing of the short message according to the judgment result of the short message center includes the release of the normal short message, that is, the short message center sends the normal short message to the receiving party; and the filtering of the harassing short message, that is, the short message center intercepts the harassing short message and does not send it to the recipient; In addition, the embodiment may also notify the SMS center to release the harassment message, but in order to remind the user, the SMS center may be notified to add the identification information to the harassment message, indicating that it is a harassment message, reminding the user to avoid being deceived, preferably, You can also use the identification information to indicate the harassment of the text message. Types of.

The short message filtering method of the embodiment uses the first determining condition in the determining rule to determine the content of the short message, and can accurately determine whether the short message to be determined is a harassing short message. Compared with the prior art, the first type of harassing interception The method only determines the harassing short message based on the sending behavior of the sender number. This embodiment has the advantages of more accurate judgment and lower false positive rate, and if the number of sending the harassing short message is reduced, the transmission frequency may be avoided. The first type of interception, but the judgment based on the content in the embodiment of the present invention is more difficult to avoid than the prior art. Therefore, the short message filtering method in this embodiment is more adaptable, and is based on the blacklist in the second harassment interception method. Judging the harassment message, the determination method based on the content of the short message in this embodiment has the advantage of more comprehensive judgment.

Further, the use of the content of the short message to be judged based on the keyword or the semantic analysis-based judgment can improve the accuracy of the spoofing short message judgment, especially the semantic analysis, so that the method for determining the harassing short message in this embodiment is more flexible, relative to the present Technically, the judgment of adapting to more types of harassing short messages is advantageous for enhancing the practicability of the short message filtering method of this embodiment.

Further, the determining rule of the embodiment further includes determining, according to the second determining condition of the number, whether the sender number of the short message is on the blacklist of the calling number, and/or determining whether the sender number of the short message is in the calling number white. On the list. By using the calling number white list for matching, it is possible to protect the short message whose sending number is on the white list but is misjudged as the harassing short message; if the calling number blacklist is used for matching, the harassment which is not determined by the short message content judgment manner can be used. SMS is authenticated to avoid reducing the user experience.

Further, after the harassment message is determined, the harassment message is stored for the user to query and delete, and the spoofing can be saved when the erroneous filtering occurs, the user is prevented from missing the important information, causing the user's loss, and the user can be conveniently managed to harass the message. Improve the user's sense of use.

Embodiment 2:

Referring to FIG. 2, this embodiment provides a short message filtering system 2, including:

The receiving module 21 is configured to receive a short message to be determined sent by the short message center;

The determining module 22 is configured to determine, according to the preset determining rule, whether the short message is a harassing short message, and the determining rule includes: determining whether the content of the short message meets the first determining condition of the preset short message content;

The sending module 23 is configured to send the determination result to the short message center, and notify the user to filter the short message to be determined that is determined to be the harassing short message.

Considering that the content of the harassment message can include words extracted directly from the content of the message, and according to the text message The result of the semantic analysis of the content is analyzed. In this embodiment, the accuracy of the determination according to the content of the short message to be determined is high. Preferably, in this embodiment, the determining module 22 includes the keyword determining sub-module 221 and the semantics. Judging at least one of the sub-modules 222:

The keyword determining sub-module 221 is configured to match the content of the short message to be determined with the preset suspected spoofing short message keyword, and determine, according to the matching result, whether the content of the short message to be determined satisfies the first determining condition of the preset short message content;

The semantic judgment sub-module 222 is configured to perform semantic analysis on the content of the short message to be determined, and match the analyzed semantics with the semantics of the preset suspected harassing short message, and determine, according to the matching result, whether the content of the short message to be determined satisfies the preset short message content. The first judgment condition.

In this embodiment, the keyword judging sub-module 221 and the semantic judging sub-module 222 may be used to determine the judging message to be judged. The matching may be performed by using the keyword judging sub-module 221 to determine that the content of the to-be-determined short message is not pre-determined. When the keyword suspected of harassing the short message is set, the semantic judgment module 222 is used to perform semantic analysis on the to-be-determined short message, and the analyzed semantics are matched with the semantics of the preset suspected harassing short message, and if the matching is successful, the judgment is to be determined. If the short message is determined to be a harassing short message and the matching fails, the short message to be determined is determined to be a normal short message.

The advantage of the keyword judging sub-module 221 and the semantic judging sub-module 222 is that two different judging methods can be used for judging a short message to be judged, and the correctness of the judging short message is determined as the harassing short message, so that the system can Timely judgments of harassing text messages that are more and more sophisticated.

In this embodiment, the keyword setting of the suspected harassing short message may be referred to the relevant part of the first embodiment. The keyword determining sub-module 221 of the embodiment determines that the content of the short message is matched with the preset keyword of the suspected harassing short message. The process is actually a process of judging whether a keyword suspected of harassing a short message appears in the short message to be judged. Therefore, the keyword judging sub-module 221 has the advantages of being simple, convenient, and easy to implement.

Similarly, for the setting of the semantics of the suspected harassing short message of the embodiment, reference may be made to the setting of the keyword of the suspected harassing short message of the first embodiment. The semantic judgment sub-module 222 can match the semantics of the content of the short message to be determined according to the semantics of the predetermined suspected harassment message, and the same or similar semantics can be regarded as a successful match. Although the analysis method used by the semantic judgment sub-module 222 is more complicated, considering that the words harassing the short message such as fraudulent short messages are more and more difficult to identify, the second method can be used to comprehensively analyze the content of the short message to obtain relevant semantics. The analysis of the judgment message is more comprehensive and flexible, and can identify the suspected harassment message to a greater extent.

The determination methods adopted by the keyword determination sub-module 221 and the semantic judgment sub-module 222 are based on short messages. The judgment of the content is performed, and the sender number of the short message is used as a basis for judging the harassment message. Preferably, the determination rule of the embodiment further includes whether the sender number of the short message satisfies the preset number. The second judgment condition.

At the same time, in consideration of the above-mentioned content judgment manner, it may be determined that a misjudgment may occur. In order to cope with the situation and improve the judgment accuracy of the embodiment, the present embodiment may set the calling number white list to the sender number to belong to the calling number. The whitelisted text message is judged to be a normal text message. In the embodiment, the blacklist of the calling number can be set, and the short message belonging to the blacklist is determined as the harassing short message.

Preferably, the determining module of the embodiment further includes a number determining sub-module 223, configured to determine whether the sender number of the short message is on the blacklist of the calling number, and/or determine whether the sender number of the short message is in the white list of the calling number. on.

In this embodiment, the whitelist of the calling number can be implemented by the user uploading his own address book. The blacklist of the calling number can include the number set by the user and the abnormal sender number transmitted by the system side. The abnormal sender number includes: The sender sends the sender's number whose behavior is abnormal. Therefore, preferably, the number judging sub-module 223 of the embodiment is further configured to receive the abnormal sender number transmitted by the system side, and record it in the blacklist of the calling number. The abnormal sender number includes: the short message sending behavior is abnormal. The sender's number.

The abnormal sending behavior here indicates that the frequency, time, etc. of the sender sending the short message does not satisfy the normal situation. According to the number of times the calling number sends the short message in the unit time, it can be judged whether the sender's behavior is abnormal, for example, when a certain calling party If the number of times the number of the short message is sent within one minute exceeds the preset threshold, the sending behavior of the number may be determined as an abnormal sending behavior. At this time, the short message sent by the number may be a harassing short message; The calling number sends the time of the short message to judge. For example, a certain number is in the morning break and other regular rest time, and the message is still sent continuously. The sending behavior of the number is not a normal sending behavior, and the sent short message may be a harassing short message. Therefore, in this embodiment, the abnormal sending number is received and recorded in the blacklist of the calling number, so that the harassing short message can be more accurately determined.

Considering that over time, the user's address book and user-defined blacklist numbers will change, and the types of harassing text messages will increase, and the keywords or semantics of suspected harassing text messages will increase, and the original The judging rule may reduce the accuracy of the spoofing message filtering. In order to meet the needs of the user, the embodiment further includes an interaction module 24 for accepting the modification of the judging rule by the user, and updating the judging according to the modification of the user. rule.

Preferably, the interaction module 24 can provide an interactive page for the user, and the user can perform the interaction on the interactive page. The management of the judgment rule includes querying and modifying the first judgment condition and the second judgment condition, and modifying the whitelist and the blacklist of the calling number includes deleting or adding the calling number, or synchronizing the current communication of the user again. Recorded as a new whitelist of calling numbers.

After the sending module 23 sends the judgment result to the short message center, the short message center filters the harassing short message according to the received judgment result, that is, does not send the harassing short message to the receiving party, and considering the above judgment, the harassing short message error may occur. In the case of judgment, in order not to cause greater losses to the user, it is necessary to provide the user with the opportunity to save and provide the user with the function of querying the harassing short message. Based on this consideration, preferably, the short message filtering system 2 of the embodiment further includes a storage module 25 for storing the harassing short message for subsequent query and use by the user. At the same time, the storage module 25 can store the harassment message according to the type of the harassment message, and display the number of unread harassment messages on the interaction interface provided by the interaction module 24, prompting the user to view the error. The situation provides the possibility of salvation.

In this embodiment, the determining module 22 may use the first determining condition and the second determining condition to implement a second-level determination of whether the short message is to be harassed, and the determining unit 22 performs the second-level judgment. The order of use of the second judgment condition is not limited, and the second-level judgment method of the judgment module 22 includes:

Method 1: The first step, the number judgment sub-module 223 matches the sender number of the short message to be determined with the number on the white list of the calling number. If the matching is successful, the short message to be determined is a normal short message, and the second short message is not required. At the first level, if the match fails, the next level of judgment is made;

Or the number judgment sub-module 223 matches the sender number of the short message to be determined with the number on the blacklist of the calling number, and if the matching is successful, the short message to be determined is a harassing short message, and the next level of judgment is not required. If the match fails, the next level of judgment is made;

In the second step, the keyword judging sub-module 221 matches the content of the to-be-determined short message with the preset suspected spoofing short message key, and the matching is successful, and the short-message text message is determined as the harassing short message, and the matching fails, and the short-sending short message is judged. For normal text messages.

Alternatively, the semantic judgment sub-module 222 performs semantic analysis on the content of the determined short message, and matches the analyzed semantics with the semantics of the preset suspected harassing short message, and the matching is successful, and the determined short message is determined as a harassing short message, and the matching fails. The to-be-determined short message is judged as a normal short message.

Manner 2: The first step, the keyword determining sub-module 221 matches the content of the short message to be determined with the default suspected spoofing short message key, and the matching is successful, and the next step is judged, the matching fails, and the short message to be determined is determined to be normal. SMS.

Alternatively, the semantic judgment sub-module 222 performs semantic analysis on the content of the determined short message, and matches the analyzed semantics with the semantics of the preset suspected harassing short message, and the matching is successful, and the next step is judged, the matching fails, and the short message to be determined is determined. For normal text messages.

In the second step, the number determining sub-module 223 matches the sender number of the short message to be determined with the number on the white list of the calling number. If the matching is successful, the short message to be determined is a normal short message. If the matching fails, the method is to be determined. The text message is judged as a harassment message.

Or, the number judging sub-module 223 matches the sender number of the short message to be determined with the number on the blacklist of the calling number. If the matching is successful, the short message to be determined is a harassing short message, and if the matching fails, the short message to be determined is determined as Normal text message.

In this embodiment, the determining module 22 may determine the harassing short message according to the short message content and the sender number, and may also determine according to other information of the short message, for example, according to the sending time of the short message, the sending location, the attribution of the sender, and the like. The information determines whether the short message to be judged is a harassing short message. The specific judgment sub-conditions can be freely set by the user according to the actual situation. For example, the user can judge the short message with the receiving time between 2:00 and 6:00 as the harassing short message.

It is conceivable that the short message filtering system of the present embodiment can be provided by the operator for the user, and the corresponding service can be referred to as a short message filtering service, and the service can be provided as a value-added service for the user. In this embodiment, the short message filtering system may further include a service receiving module 26, configured to open a short message filtering service or cancel the short message filtering service for the user. The specific opening mode may be that the service receiving module 26 receives the short message sent by the user, and registers the short message filtering service for the user according to the short message, or receives the registration information input by the user on the network to register the short message filtering service for the user. The sending module 23 of the embodiment may further send the information of the registered user to the short message center, and control the short message center to use the short message that the registered user needs to receive as the judgment to send the short message to the short message filtering system to determine whether the message is a harassing short message.

Referring to FIG. 3, it is a typical network deployment diagram. The short message filtering system in the figure is implemented by the short message filtering system in this embodiment, and the short message center is implemented by using an existing short message center.

The list of contacts is set to be the white list of the calling number, and the blacklist uploaded by the user is used as the blacklist of the calling number. In this embodiment, the service acceptance module 26 can also be used for user service attribute setting.

It can be understood that the second-level judgment result of the embodiment includes the short message to be determined as a harassment short message or a normal short message. The sending module 23 sends the determination result to the short message center, and the processing of the short message center according to the judgment result includes: releasing the normal short message, that is, the short message center sends the normal short message to the receiving party; or filtering the harassing short message, that is, the short message center will The spoofing SMS interception is not sent to the recipient; in addition, the sending module 23 of the embodiment may also notify the short message center to release the harassing short message, but in order to remind the user, the sending module 23 may notify the short message center to send the harassing short message. The identification information is added to indicate that it is a harassment message, and the user is reminded to avoid being deceived. Preferably, the information indicating the type of the harassment message is added to the identification information, and the type of the harassing message is advertised to the user to prevent the user from receiving the scam. SMS spoofing.
