The following detailed description of embodiments of the present application will be made with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present application, are given by way of illustration and explanation only, and are not intended to limit the present application. It will be apparent to one skilled in the art that the present application may be practiced without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present application by illustrating examples thereof.
The harassing call refers to a call which is made by some merchants to promote products or is fraudulently made by some persons serving as staff of an authority department to ordinary users, the ordinary users may continuously receive spam messages sent by networks or mobile numbers and other various types of communication harassments, and the various types of harassment numbers carried out by using operator networks as carriers are more and more, so that the customer experience is poor.
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
Fig. 1 shows a schematic flow chart of a method for identifying a harassment number in an embodiment of the present application. The harassment number identification method can be applied to a harassment number identification server. As shown in fig. 1, the following steps are included.
And step 110, obtaining and sending customer complaint information to the block chain network.
When each operator node obtains customer complaint information from the blockchain network, the customer complaint information is subjected to message analysis, and suspected numbers in the customer complaint information and call record information corresponding to the suspected numbers are obtained. Each operator node can search the database in the operator node in parallel according to the suspected number, screen the suspected number and accelerate the troubleshooting of harassing numbers.
The fused suspected user information is a set of information of suspected users fed back by each operator node according to the customer complaint information, and the suspected users are users who use suspected numbers for communication.
And step 130, determining whether the suspected number is a harassment number according to the fused suspected user information.
In some specific implementations, determining whether the suspected number is a nuisance number according to fusing the suspected user information includes: extracting an authentication identifier of a suspected user, call record information corresponding to the suspected number and position information of the suspected user during call in the fused suspected user information, wherein the authentication identifier is an identity identifier determined by an operator node according to authentication information of a legal organization received by the suspected user; determining whether the suspected user is a legal user according to the identity authentication identifier; when the suspected user is determined not to be a legal user, determining that the suspected number is a harassing number; and when the suspected user is a legal user, further determining whether the suspected number is a harassing number according to the call record information corresponding to the suspected number and the position information of the suspected user during the call.
For example, the fused suspected user information includes a suspected number 1341xxxxxx4, where x is any one of 0 to 9. The suspected user corresponding to the suspected number is a certain king, the position of the certain king when calling service is carried out by using the number 1341xxxxxx4 is a first street, when the suspected user information is analyzed and fused, the obtained authentication identifier of the certain king represents that the certain king is not a legal user (for example, when an operator node can inquire that the certain king receives an authentication short message sent by a bank/government agency from a database, the authentication identifier of the certain king is set as a legal user, otherwise, the authentication identifier of the certain king is set as an illegal user), and the suspected number 1341 xxxxxxxx 4 is determined to be a harassing number. When it is determined that the authentication identifier of a certain king is a valid user, it is further required to determine whether the suspected number is a harassment number through the call record information corresponding to the suspected number 1341 xxxxxxxx 4 and the location information (for example, the first street, etc.) of the suspected user when the call is made.
Preliminarily judging whether the suspected number used by the suspected user is a harassing number according to the identity authentication identifier of the suspected user, and accelerating the speed of checking the harassing number; and then further judging whether the suspected number is a harassment number or not according to the call record information corresponding to the suspected number and the position information of the suspected user during the call. The troubleshooting accuracy of the harassment numbers is improved.
In some specific implementations, determining whether the suspected number is a harassment number according to the call record information corresponding to the suspected number and the position information of the suspected user during the call includes: determining a called number group and call duration corresponding to a call initiated by a suspected user according to call record information corresponding to the suspected number; determining calling frequency information of a suspected user in the same time period at the same position according to the calling time length and the position information of the suspected user during the calling; when the called number in the called number group is determined to be a preset number, the frequency of the suspected user initiating the call exceeds a preset frequency threshold, and the call duration is a preset duration, determining that the suspected number is not a harassing number; and when the called number in the called number group is not a preset number, determining whether the suspected number is a harassing number according to the calling frequency information and the frequency preset threshold.
For example, setting the preset frequency threshold to be 4 calls within 1 minute, the pseudo-number 1341xxxxxx4 calls a plurality of called numbers for a plurality of times, and when the called number called by the pseudo-number 1341 xxxxxxxx 4 is a preset number such as a customer service number (e.g., 10011) or an emergency number (e.g., 110, 119, etc.) of an operator, even if the frequency of calling initiated by the pseudo-number 1341xxxxxx4 is 6 calls within 1 minute, and is greater than the preset frequency threshold, the pseudo-number 1341 xxxxxxxx 4 is not a harassing number, because the pseudo-number 1341xxxx 4 does not have a bad effect on other users, and does not disturb normal calls of other users.
For example, when the called number in the called number group is not a preset number, if the calling frequency information is greater than a frequency preset threshold, it is determined that the suspected number is a nuisance number; otherwise, if the calling frequency information is less than or equal to the frequency preset threshold, determining that the suspected number is not a harassing number.
It should be noted that the suspected number may be one number or multiple numbers, if the suspected user uses multiple mobile terminals to call multiple common numbers at the same time (for example, within a half of a time period from 2 pm to 2 pm) at the same position (for example, all in a 606 room of the first building), and the multiple operator nodes query their internal databases, so that the related communication information of the suspected numbers can be quickly located, the investigation and confirmation of the suspected numbers are accelerated, the interception of harassing numbers is promoted, and the normal communication of the common user is ensured.
In the embodiment, each operator node obtains customer complaint information by obtaining and sending the customer complaint information to the blockchain network; and each operator node can screen suspected numbers according to the customer complaint information, so that the troubleshooting of harassing numbers is accelerated. Acquiring fused suspected user information from a block chain network; through a communication mode of a block chain, fused suspected user information which is reported by a plurality of operator nodes and screened by each operator is obtained in the service range of the operator nodes, the investigation range of suspected numbers is expanded, and the investigation efficiency of the suspected numbers is improved. And determining whether the suspected number is a harassing number according to the fused suspected user information without manual examination, so that the operation cost is reduced while the safe use of normal users is ensured, and the development of mobile communication services is facilitated.
Fig. 2 is a schematic flow chart illustrating a method for identifying a harassment number in another embodiment of the present application. The harassment number identification method can be applied to a harassment number identification server. As shown in fig. 2, the following steps are included.
And step 210, obtaining and sending customer complaint information to the block chain network.
And step 230, determining whether the suspected number is a harassment number according to the fused suspected user information.
It should be noted that steps 210 to 230 in this embodiment are the same as steps 110 to 130 in the previous embodiment, and are not described again here.
And 240, when the suspected number is determined to be a harassment number, generating and sending a shielding broadcast message to the block chain network according to the harassment number.
When each operator node obtains the harassing numbers in the shielding broadcast message from the block chain network, the harassing numbers are added into a blacklist to prohibit the call service of the harassing numbers.
In this embodiment, through a communication manner of a block chain, fused suspected user information that is reported by a plurality of operator nodes and screened by each operator is obtained within a service range of the plurality of operator nodes, so that a suspected number investigation range is expanded, and suspected number investigation efficiency is improved. According to the fused suspected user information, whether the suspected number is a harassing number is determined, manual examination is not needed, and the operation cost is reduced while the safe use of normal users is guaranteed; and then generating and sending a shielding broadcast message to the block chain network according to the harassment number, so that each operator node can add the harassment number to a blacklist in time, namely, the harassment number is listed as an unavailable number, the harassment number can not call a service any more, other users can be ensured not to be harassed by the harassment number, and the user experience is improved.
Fig. 3 is a flowchart illustrating a method for identifying a harassment number in yet another embodiment of the present application. The harassment number identification method can be applied to an operator node server. As shown in fig. 3, the following steps are included.
And step 310, obtaining customer complaint information sent by the harassment number identification server from the blockchain network.
The customer complaint information comprises a suspected number and call record information corresponding to the suspected number. For example, the pseudo number 1341xxxxxx4, and the call record information corresponding to the pseudo number 1341xxxxxx4 may include the call duration, the called number, the start time of the call, and the geographic location information (e.g., the specific latitude and longitude information) of the user of the pseudo number 1341xxxxxx4 when the call is made. The above-mentioned call record information is only an example, and may be specifically set according to the actual situation, and other call record information not described is also within the protection scope of the present application, and is not described herein again.
For example, from the service range of the current operator node, it is searched whether a suspected number 1341xxxxxx4 exists, and if so, it is determined that the suspected number 1341xxxxxx4 is a service user of the current operator node; otherwise, it is determined that the suspected number 1341xxxxxx4 is not a service subscriber of the current operator node, and the current operator node cannot perform query processing on the suspected number.
It should be noted that, if it is determined that the suspected number is a service user of the current operator node, step 330 is executed; otherwise, the flow ends.
For example, the information of the first suspected user may include: the suspected number 1341xxxxxx4, the identity (e.g., identification number) of the first suspected user corresponding to the suspected number 1341xxxxxx4, the location information of the first suspected user during the call, the call record information corresponding to the suspected number, and the like.
In some implementations, determining information of the first suspected user according to the suspected number includes: inquiring a database of a current operator node according to the suspected number to obtain call record information corresponding to the suspected number and position information of a first suspected user during call; acquiring verification information of a legal organization on a first suspected user; determining an identity authentication identifier of the first suspected user according to the authentication information; and determining the information of the first suspected user according to the call record information corresponding to the suspected number, the identity verification identifier of the first suspected user and the position information of the first suspected user during the call.
The verification information of the legal organization for the first suspected user can be determined in the following way: searching a database of a current operator node, and if a first suspected user receives a verification short message record sent by a bank/government agency from the database, the first suspected user is verified to pass by a legal agency, namely the first suspected user is considered to be a legal user by the legal agency; otherwise, the legal organization does not verify the first suspected user, that is, the legal organization considers the first suspected user to be an illegal user.
It should be noted that the information of the second suspected user fed back by the second operator node may be information obtained by the second operator node searching its own database according to the customer complaint information sent by the harassment number identification server; or the comprehensive judgment may be performed through the acquired information of the third suspected user fed back by the third operator node and the customer complaint information sent by the harassment number identification server, and the acquired information of the first suspected user is fused with the information of the third suspected user, for example, the geographical location information of the first suspected user is the same as the geographical location information of the third suspected user, and both the two users initiate a call service within a certain time period. The method expands the search range of suspected numbers and improves the accuracy of troubleshooting of harassing numbers.
When the harassment number identification server obtains the fused suspected user information, whether the suspected number is a harassment number or not is determined according to the fused suspected user information. The fusing the suspected user information comprises: the method comprises the steps of identifying an operator node, a suspected number set, call record information corresponding to suspected numbers in the suspected number set, identity verification identification of suspected users corresponding to the suspected numbers and position information of the suspected users during call.
In some implementations, generating and sending fused suspected user information to a blockchain network according to information of a first suspected user and information of a second suspected user includes: extracting first position information and first call record information of a suspected user during call in the information of the first suspected user; extracting second position information and second communication record information of the suspected user when the suspected user is in communication in the information of the second suspected user; determining calling frequency information of suspected numbers in a suspected number set according to the first position information, the first call record information, the second position information and the second call record information, wherein the suspected numbers are numbers which initiate calling in the same time period at the same position; determining fused suspected user information according to the calling frequency information and a frequency preset threshold; and sending the fused suspected user information to the block chain network.
In the embodiment, customer complaint information sent by a harassing number identification server is obtained from a block chain network, a database of an operator node is queried according to the customer complaint information to determine whether a suspected number exists, and the suspected number is sent to the harassing number identification server when the suspected number is determined to exist; and/or acquiring the relevant information of the suspected numbers sent by other operator node servers, fusing the relevant information with the relevant information of the suspected numbers inquired by the database of the operator node servers, acquiring and sending the relevant information fused with the suspected numbers to the harassing number identification server, so that the harassing number identification server can comprehensively judge whether the suspected numbers have harassing numbers, further process the harassing numbers, reduce the harassment of the harassing numbers to users and improve the user experience.

Fig. 6 is a block diagram showing a component of a disturbance number identification system in an embodiment of the present application. As shown in fig. 6, includes: the system comprises a first operator node server 601, a second operator node server 602, a third operator node server 603 and a harassing number identification server 604 which are connected through a blockchain network.
Fig. 7 is a flowchart illustrating a working method of a harassment number identification system in an embodiment of the present application. As shown in fig. 7, the method specifically includes the following steps.
In step 701, the harassment number identification server 604 acquires customer complaint information from the blockchain network, signs the customer complaint information with a private key of the harassment number identification server, and generates and sends the signed customer complaint information to the blockchain network, so that each operator node (for example, the first operator node server 601, the second operator node server 602, and the third operator node server 603) acquires the customer complaint information.
The customer complaint information is complaint information of the customer for some telephone numbers or a certain telephone number, and the customer complaint information may include a suspected number and call record information (for example, call time of the suspected number, etc.) corresponding to the suspected number.
Step 702, after receiving the customer complaint information signed by the first operator node server 601, verifying the private key signature, when the verification is passed, obtaining a first suspected number and the calling time of the first suspected number, if it is determined that the first suspected number is the number of the communication service provided by the first operator node server 601, the first operator node server 601 queries its own database according to the first suspected number, extracts the call record information corresponding to the first suspected number and the location information of the first suspected user corresponding to the first suspected number, and obtains the verification information of the first suspected user by the legal organization (for example, if the first suspected user receives the verification short message record sent by the bank/government organization from the database, it indicates that the verification of the first suspected user by the legal organization is passed, i.e. the legal organization considers that the first suspected user is the legal user, otherwise, the first suspected user is not verified by the legal organization, namely the first suspected user is considered as an illegal user by the legal organization); then, a set of initial suspected numbers initiating a call in the same geographic location in the same time period is determined according to the information (i.e., the call record information corresponding to the first suspected number, the location information of the first suspected user during the call, and the verification information of the first suspected user by the legal organization), where it should be noted that the initial suspected numbers may be abnormal numbers in which the call initiating frequency in the same cell or a neighboring cell exceeds a preset threshold.
Wherein the first broadcast message includes the following information: the identifier of the first operator node server 601, the first suspected number queried in step 702, the call record information corresponding to the first suspected number, the location information of the first suspected user when the first suspected user makes a call, and the set of the authentication information of the legal organization for the first suspected user and the initial suspected number.
It should be noted that the fused suspected number set may be a subset of the initial suspected number set, or may be the initial suspected number set, and the fused suspected number in the specific fused suspected number set is determined according to a query result obtained by querying the database by the second operator node 602.
It should be noted that, while the first operator node server 601 executes step 702 and step 703, the third operator node server 603 also queries its own database to determine the specific information of the suspected number, and steps 706 to 707 executed by the third operator node server 603 are the same as steps 702 to 703, and are not repeated here, so that the harassing number identification server 604 can obtain the third broadcast message sent by the third operator node server 603. The third broadcast message includes: the third suspected number, the call record information corresponding to the third suspected number, the position information of the third suspected user during the call, and the verification information of the legal organization on the third suspected user and the set of the initial suspected numbers.
In some specific implementations, the third operator node server 603 may also obtain, through the blockchain network, the first broadcast message sent by the first operator node server 601, or the second broadcast message sent by the second operator node server 602; then, step 706 to step 707 are executed, it should be noted that, step 706 to step 707 are the same as the operation methods of step 704 to step 705, and the difference is that the database queried in step 706 to step 707 is the database of the third operator node server 603, so as to more accurately narrow the range of the suspected number, and facilitate the subsequent processing of the harassment number identification server 604.
In step 708, the harassment number identification server 604 obtains the second broadcast message sent by the second operator node server 602 and the third broadcast message sent by the third operator node server 603 from the blockchain network, respectively. When the private key signatures of the two broadcast messages pass verification, the following information is obtained: fusing a suspected number set, the identifier of the second operator node 602, the call record information corresponding to the fused suspected number in the suspected number set, the obtained identity verification identifier of the fused suspected user corresponding to the fused suspected number, and the position information of the fused suspected user during the call; the third suspected number, the call record information corresponding to the third suspected number, the position information of the third suspected user during the call, and the verification information of the legal organization on the third suspected user and the set of the initial suspected numbers.
Then, when the suspected user is not a legal user, the suspected number is determined to be a nuisance number. When the suspected user is a legal user, determining a called number group and call duration corresponding to a call initiated by the suspected user according to the call record information corresponding to the suspected number; determining calling frequency information of a suspected user in the same time period at the same position according to the calling time length and the position information of the suspected user during the calling;
when it is determined that the called number in the called number group is a preset number (e.g., an emergency call number such as 110, 119, or the like, or a customer number of an operator, or the like), the frequency of initiating a call by a suspected user exceeds a preset frequency threshold (e.g., the preset frequency threshold is 5 times, or 10 times, or the like, of initiating a call per minute), and the duration of a call is a preset duration (e.g., 15 seconds, 60 seconds, or 30 minutes, or the like), it is determined that the suspected number is a test number, not a nuisance number.
When the called number in the called number group is not a preset number, if the calling frequency information is greater than a frequency preset threshold value, determining that the suspected number is a harassing number; otherwise, determining that the suspected number is not a harassing number.
In step 709, the harassment number identification server 604 generates and sends a screening broadcast message to the block chain network according to the harassment number determined in step 708, so that the first operator node server 601, the second operator node server 602, and the third operator node server 603 obtain the harassment number, add the harassment number to the blacklist, and prohibit the call service of the harassment number.
In the embodiment, customer complaint information is sent to the blockchain network through the harassing number identification server, so that each operator node server in the blockchain network can inquire a database of the operator node server through the customer complaint information to determine whether a suspected number exists or not, and when the suspected number exists, the suspected number is sent to the harassing number identification server; and/or acquiring the relevant information of the suspected numbers sent by other operator node servers, fusing the relevant information with the relevant information of the suspected numbers inquired by a database in the operator node server, acquiring and sending the relevant information fused with the suspected numbers to the harassing number identification server, so that the harassing number identification server can comprehensively judge whether the suspected numbers have harassing numbers, further process the harassing numbers, reduce the harassment of the harassing numbers to users and improve the user experience.
