Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Example one

The embodiment of the invention provides a telephone reporting method based on a mobile terminal.

Referring to fig. 1, a flowchart illustrating steps of a mobile terminal based telephone reporting method in an embodiment of the present invention is shown.

And step 100, acquiring a telephone number ciphertext of the mobile terminal where the incoming call client is located, and sending the telephone number ciphertext to a server for identification.

In the embodiment of the invention, when receiving an incoming call, the operating system of the terminal broadcasts the incoming call message and carries the incoming call number, so that the application program can monitor the event and acquire the telephone number of the incoming call from the event, and further, the application program can read the data in the address book stored in the terminal by the user through the interface provided by the operating system of the terminal. When the user is used as a calling party to make a call, the calling-out event can be monitored in a similar mode, and information such as the telephone number of the called party can be acquired from the local place.

In the embodiment of the invention, the types of the strange telephone numbers needing to be sent to the server for identification can comprise house agency, express meal delivery, education and training, harassing calls, fraudulent calls or public service classes and the like. The present embodiment does not limit the classification information to which the strange number belongs, and the classification information may be a classification of a large class or a detailed classification information of a certain large class.

In the embodiment of the invention, the mobile terminal can determine the type of the strange number according to the mark library used for indicating the type of the number. The tag library may be a tag library local to the mobile terminal or a tag library on the server side. The mark library comprises: the server may transmit the correspondence in the tag library to the mobile terminal. Where numbers may be classified into many security classes from white to black, marked with different colors, e.g. red for fraud calls, orange for advertising nuisance and premises agents, and green for normal numbers. In this embodiment, a range may be set for the security level of the mark, for example, the security level of express food delivery is 100, the security level of advertising is 200, and fraud is higher. The types of strange numbers may include: white numbers, unlabeled numbers, advertisement nuisance numbers, house property intermediary numbers, fraud numbers, express numbers, meal delivery numbers, etc. Each number in the label library corresponds to a number type, and the correspondence may be determined by the network side, or may be recorded by notifying a server on the network side after the mobile terminal labels the number. For example, in the tag library, the classification information to which the strange number belongs may include: number attribution information and number attribution domain information; or the type of the number can be determined according to the classification information, wherein the number belongs to the information, the number belongs to the field information and the number belongs to the information of the user. For example, there is classification information "15210 ×, i love my home", and through the pre-trained classifier and information matching, it can be known that the type of this number belongs to is the house property broker. The embodiment of the present invention is not limited to this, and before the phone number is sent to the server, the phone number may be encrypted by using an Algorithm such as md5(Message Digest Algorithm 5, fifth version of Message Digest Algorithm) or sha1(Secure Hash Algorithm), and a dedicated transmission channel may be selected to send the phone number to the server.

And 102, receiving an identification result which is fed back by the server and indicates that the telephone number is a suspicious number, and starting to record the telephone audio of the mobile terminal when the mobile terminal is connected with the telephone number.

The server identifies the received telephone number, and can obtain several types of identification results, such as a security number, a suspicious number and the like, and when the telephone number is identified as the suspicious number by the server, the server can start to record telephone audio.

Wherein the suspect number may be a nuisance number, an advertisement number, an intermediary number, a fraud number, and the like.

In the embodiment of the invention, the number corresponding to the mark in the mark library consists of a number which takes the location of the server as a home location and a number without the home location. In this embodiment, the local phone corresponding to the tag is mainly issued to the mobile terminal in a regional manner, and meanwhile, some national phone corresponding tags (for example, some 400 phone corresponding tags) are issued to the mobile terminal, so that the hit rate for determining the type of the incoming call number can be improved.

In this embodiment, the tag library in the mobile terminal may be acquired from the server, and when there are many tags in the tag library, the server may send only N data of the header (for example, 15 ten thousand data of the header) to the mobile terminal, where the N data of the header represents the first N data with a large tag amount. By the embodiment, the data transmitted by the network is limited, and the network overhead can be effectively saved.

The tag library may include a header database, which may include: information of strange numbers corresponding to public service classes; and the information corresponding to the unfamiliar number is provided by the user of the unfamiliar number. For example: the header data may be "95588 china industrial and commercial bank service telephone", "10086 china mobile customer service telephone", and the like. That is, the header database may be unambiguous numbers and classification information of the numbers determined by the cloud server.

In specific implementation, the type corresponding to the unfamiliar number may be sent to the monitoring device, so that the type is displayed on a current incoming call or outgoing call interface of the terminal. When the user calls the interface display "15210 x, the property broker", the user can easily identify the user information of this number. According to the method, the classifier is trained in advance to search the type corresponding to the unfamiliar number, so that the type of the unfamiliar number displayed in the terminal is accurate, and a user can judge the classification of the incoming call or the outgoing call number by acquiring the related information of the incoming call or the outgoing call number, so that great convenience is brought to the user.

In another preferred example of the embodiment of the present invention, when the mobile terminal does not inquire the type of the unfamiliar number in a local tag library, the mobile terminal inquires the type of the unfamiliar number from a server, and then the server determines the type of the unfamiliar number according to the tag library in the server; and the mobile terminal receives the type of the strange number sent by the server. In the embodiment, the mobile terminal determines the type of the unfamiliar number through the server-side tag library, and the server-side tag library is updated more timely than the mobile terminal-side tag library, so that the accuracy of the unfamiliar number type determined by the embodiment is higher.

In this embodiment, the server may determine the classification information of the number according to a domain dictionary, where the domain dictionary may be a multi-dimensional vector forming dictionary, and each dimension of the domain dictionary corresponds to one or more domain feature words in a domain, and a probability distribution of the domain feature words in the domain. For example, one dimension in the domain dictionary corresponds to the domain serving the mobile client, and the domain feature words are: china mobile customer service class phone, the probability distribution of the China mobile customer service class phone in the mobile customer service field is 100%.

Or, the domain corresponding to one dimension in the domain dictionary is a real estate agency, and the domain feature words are: "i love my home", "rent house", "sell house", "chain property", "house renting agent", etc., the probability distribution of "i love my home" in the property agent field is 100%.

For example: the cloud server receives the same unfamiliar number reported by the 6 monitoring devices and the category to which the unfamiliar number belongs within a week, but the category to which the unfamiliar number reported by each monitoring device belongs is different, for example, the categories are 'house agency', 'advertising promotion', 'express delivery', and the like.

At this time, the unfamiliar number needs to be searched in a search to obtain the feature words in the yellow page of the unfamiliar number. It should be noted that the yellow page at this point may be understood as the closest one of the related web pages of the unfamiliar number, and the web page appearing second in the search may be the yellow page of the unfamiliar number 10086, so that the feature word may be: china mobile customer service telephone. By comparing the feature word 'Chinese mobile customer service telephone' with the field feature words in the field dictionary, the field feature word with the largest similarity is 'Chinese mobile customer service type telephone', so that the field 'mobile customer service' corresponding to the field feature word is used as the classification information of the unfamiliar number 10086, and the type of the number can be determined.

In addition, the strange numbers reported by the monitoring device and received by the cloud server are as follows: 010 + 821, inputting the number into a search engine, selecting the feature words "love my home", "rent room", and "sell room" from a related webpage related to 010 + 821, comparing each feature word with the feature words in the domain dictionary, and selecting the domain "house agency" corresponding to the domain feature words "love my home", "rent room", and "sell room" with the highest similarity as the classification information of 010 + 821.

In the embodiment of the present invention, the process of recording the telephone audio may be started when the identification result indicating that the telephone number is a suspicious number is received (at this time, the mobile terminal does not access the telephone number), or may be started when the mobile terminal accesses the telephone number.

And 104, when the call between the mobile terminal and the telephone number is finished, sending the recorded telephone audio cipher text to the server.

And when the call between the mobile terminal and the telephone number is finished, the telephone number can be actively hung up for the mobile terminal, and the mobile terminal can also be passively hung up by the telephone number.

The recorded telephone audio can be encrypted, and the encrypted telephone audio ciphertext is sent to the server. The dedicated transmission channel may also be selected when transmitting the telephone audio ciphertext, and may be implemented based on a local Private Network (VPN client) service created inside the client, for example. In this context, the client may be a mobile terminal device with a mobile networking service, such as a smart phone, a tablet computer, or the like. The client's operating system opens multiple system interfaces (APIs) to facilitate use of the VPN service, which can obtain the authority to control and manage other applications upon user confirmation. Specifically, by calling an API provided by an operating system, a VPN service inside the client may be opened, and when other applications of the client want to access the network, query requests sent by the client to the server are all processed by the local VPN service, and a local service process provided by creating the local VPN service inside the client is used for processing the voice recording call, that is: and acquiring an initiating query request by querying the system file, acquiring a corresponding processing strategy by querying the configuration file, and processing the network connection request according to the processing strategy.

In summary, in the technical scheme of the embodiment of the present invention, a phone number ciphertext of a mobile terminal where an incoming call client is located is obtained and sent to a server for identification; receiving an identification result which is fed back by the server and indicates that the telephone number is a suspicious number, and starting to record the telephone audio of the mobile terminal when the mobile terminal calls the telephone number; and when the call between the mobile terminal and the telephone number is finished, sending the recorded telephone audio ciphertext to the server to report the suspicious number. The embodiment of the invention sends the suspicious number to the server for reporting, and simultaneously sends the telephone recording of the suspicious number to the server as the reported evidence. The problem that the existing telephone reporting method based on the mobile terminal cannot provide reporting evidence so as to generate reporting disputes is solved, and the telephone 'demonstration' reporting is realized.

Example two

Referring to fig. 2, a flowchart illustrating steps of a mobile terminal based telephone reporting method in an embodiment of the present invention is shown.

And 200, acquiring a telephone number ciphertext of the mobile terminal where the incoming call client is located, and sending the telephone number ciphertext to a server for identification.

The technical means for acquiring the telephone number may adopt technical means commonly used in the art, which is not limited in the embodiment of the present invention, and meanwhile, before the telephone number is sent to the server, the telephone number may be encrypted, and a dedicated transmission channel may be selected to send the telephone number to the server.

If a telephone number is to be acquired and sent to the server for identification, a harassment interception function of the client needs to be started, as shown in fig. 3, if call recording is to be subsequently performed, a function of recording and reporting harassment calls needs to be started.

Step 202, receiving an identification result which is fed back by the server and indicates that the telephone number is a suspicious number, and starting to record the telephone audio of the mobile terminal when the mobile terminal is connected with the telephone number.

The process of recording the telephone audio may be started when the recognition result indicating that the telephone number is a suspicious number is received (at which time the mobile terminal does not connect the telephone number), or may be started when the mobile terminal connects the telephone number.

Preferably, in step 200, the process of receiving the identification result indicating that the phone number is a suspicious number and fed back by the server may be:

The suspicious numbers reported and confirmed or the suspicious numbers actively collected by the server are stored in an identification database preset in the server.

Preferably, in step 200, the process of receiving the identification result indicating that the phone number is a suspicious number and fed back by the server may further include:

If the telephone number is reported and the number marked as the suspicious number is greater than or equal to a preset threshold value in the server, preliminarily determining that the telephone number is the suspicious number, and generating a preliminary identification result indicating that the telephone number is the suspicious number; if the telephone number is reported and the number marked as the suspicious number is smaller than the preset threshold value, the telephone number can be preliminarily determined not to be the suspicious number, and a preliminary identification result showing that the telephone number is not the suspicious number is generated.

If the identification result indicates that the telephone number is a suspicious number, the identification result indicating that the telephone number is the suspicious number can be displayed, and the recording permission of the client to the telephone audio of the mobile terminal is determined to be set or a trigger instruction for starting recording the telephone audio when the telephone number is connected is received.

In the embodiment of the present invention, the server may determine the difference between the updated tag library and the tag library before the update, that is, the increment of the tag library update at certain time intervals. For example, the server may send the full amount of the token library (e.g., including the top 15 thousands of records) to the mobile terminal on the first day, and determine the difference between the token library sent the first day and the current token library on the second day, i.e., the increment between the current token library and the token library sent the first day.

If the identification result indicates that the phone number is a suspicious number, the identification result that the phone number is a suspicious number, such as 'fraud phone', can be displayed, and when the phone is not connected, the recording authority is set, such as 'recording complaint is opened', as shown in fig. 4 a. The "recording in progress" and the time recorded may be displayed in the call on state, and the number of times the telephone number is marked may also be prompted, as shown in fig. 4 b.

Preferably, in step 202, the process of starting recording the phone audio of the mobile terminal may be:

(1) and if the time length of the telephone audio of the mobile terminal is greater than or equal to a preset recording time period, recording the telephone audio of the mobile terminal according to the preset time period.

For example, if the time length of the telephone audio is 3 minutes and the preset recording time period is 15 seconds, the telephone audio with the time of 15 seconds is recorded.

(2) And if the time length of the telephone audio of the mobile terminal is less than the preset recording time period, recording the telephone audio of the whole time length.

For example, if the time length of the telephone audio is 10 minutes and the preset recording time period is 15 seconds, the telephone audio of 10 seconds is recorded.

Preferably, in step 202, from the beginning of recording the telephone audio of the mobile terminal to the end of recording the telephone recording, displaying the relevant information of the recorded telephone audio and a switch for uploading the ciphertext of the recorded telephone audio, where the relevant information includes the duration and/or file size of the recorded telephone audio.

For example, the time length of the recorded telephone audio and the space capacity occupied by the telephone audio file, etc. may be displayed, and a switch button for uploading the telephone recording may also be displayed.

The client is provided with a storage space allowing a preset number of recorded telephone audios to be stored; when the storage space is insufficient, the telephone audio in the storage space can be deleted according to a preset rule.

For example, a storage space capable of storing 5 to 10 telephone recordings is set on the client, when the storage space is not enough to store one telephone recording, all the telephone recordings in the storage space may be deleted, or the telephone audio may be deleted according to a preset rule, where the preset rule may be according to the sequence of the recording time of the telephone recording, or directly clearing the storage space, and the like.

And step 204, when the call between the mobile terminal and the telephone number is finished, sending the recorded telephone audio cipher text to the server.

The recorded telephone audio can be encrypted, and the encrypted telephone audio ciphertext is sent to the server. When the telephone audio cipher text is sent, a special transmission channel can be selected, and the safety of telephone recording transmission is ensured.

And sending the recorded telephone audio ciphertext to the server, displaying that the user is recommended to send the telephone audio ciphertext in a WIFI environment, and displaying about the required cost if the telephone audio ciphertext is sent to the server in a 2G or 3G environment.

Preferably, the step 204 may include:

substep 2041, cutting the recorded telephone recording according to a preset segment time period to obtain at least one telephone recording segment.
