Description

Control method and device for accurately identifying target terminal

Technical Field

The invention belongs to the field of operating system fingerprints, particularly relates to a terminal identification system, and particularly relates to a control method and a corresponding device for accurately identifying a target terminal.

Background

With the increasing popularity of online shopping, more and more users are used to purchase self-mental commodities through mobile terminals such as mobile phones, IPADs, tablet computers and the like based on wireless internet anytime and anywhere, on the basis, many merchants see potential commercial opportunities therein and start to push commodity advertisements interested in the commodities to the users in a targeted manner by monitoring the purchasing behaviors or purchasing intentions of the users, for example, after the users add the A commodities to a shopping website shopping cart, the commodities advertisements related to the A commodities are pushed to the A commodities within a period of time after the A commodities are received by the users to form transactions, and accordingly, the users can also purchase the A commodities again or continue the previous unexpectedly interrupted purchasing operation by receiving the A commodity advertisements.

Most of existing shopping websites, such as Taobao and No. 1 shop, use shopping carts as nodes to obtain purchasing intention or purchasing behavior information of users, users register and log in on the websites in advance, a website background server can match the purchasing intention of the users with user accounts, although continuous tracking of the purchasing behaviors of the users can be achieved to a certain extent, but the amount of information that can be obtained is limited, for example, many users are accustomed to browsing websites in the form of tourists and only log on when confirming that shopping is required, the above method of matching the user account with the user click behavior is not suitable, especially in some cases where a specific application software needs to be installed on the user terminal device to implement subsequent services, if the users do not complete the installation operation for various reasons in the software installation stage, the subsequent information of the users can not be obtained by the existing information tracking means.

In many cases, a user needs a control method capable of monitoring the operation behavior of a user or an equipment terminal at the source and determining a subsequent information release strategy through continuous tracking, for example, in the stage of installing application software by the user, the terminal ID of the currently installed application software is acquired and added into a third party list, if the software is successfully installed, the third party list is removed from the user terminal ID, and when the user sends a request for installing the software to a software background server next time, other promotion information related to the software is pushed to the software background server; on the other hand, if the software installation is unsuccessful, the user terminal ID is kept in the third party list, the software background server searches in the third party list when receiving the installation request next time, and the software installation package is sent to the software background server only when the terminal ID can be matched in the third party list.

At the present stage, there is no very good way to solve the above mentioned problems. In most cases, a merchant can only monitor the purchasing behavior of a user on a shopping page and match the purchasing behavior with the user account, and a technical scheme that a target terminal is monitored in a software installation stage of the user and matching is performed based on the ID of the target terminal is not provided.

Detailed Description

In order to better and clearly show the technical scheme of the invention, the invention is further described with reference to the attached drawings.

The technical solution of the present invention is to provide a technical solution that can accurately identify a target terminal, in order to solve the technical problem that the prior art cannot identify the target terminal and determine information distribution content based on a target terminal ID. By the technical scheme provided by the invention, the accuracy of identifying the fingerprint of the operating system of the target terminal can be greatly improved, so that an information issuing party can formulate an individualized information issuing strategy for the target terminal. Specifically, in the preferred embodiment of the present invention, the target terminal ID is identified by acquiring the characteristic information in the target terminal transmission information, and the information content finally transmitted to the target terminal is determined based on the association index thereof with the first information set.

Fig. 1 is a flowchart illustrating a control method for accurately identifying a target terminal, which is used for screening the target terminal to determine whether to send first control information to the target terminal according to a first embodiment of the present invention. Specifically, step S101 is first executed to receive first request information from the target terminal. More specifically, the first request information corresponds to the first control information, and includes request information requesting presentation of the first control information. Still further, the target terminal includes any one of a mobile phone, an IPAD, a tablet computer, a notebook computer, and the like. Preferably, the first request information includes an IP datagram, which is a basic unit of data transmitted through the wireless internet. Preferably, the IP datagram consists of a header and data. Preferably, the IP datagram is defined based on a TCP/IP protocol, wherein the header corresponds to the destination terminal ID, and the data corresponds to the first control information. In a preferred embodiment, the background server actively receives first request information from the target terminal, first sends display request information to the plurality of mobile terminals, and then receives feedback information sent by the target terminal based on user selection, where the feedback information is the first request information, for example, the background server displays app promotion information on current display windows of the plurality of mobile terminals, and if one of the mobile terminals clicks the app promotion information corresponding to the user, the mobile terminal becomes the target terminal and sends the first request information to the background server, and requests further installation information or introduction information of the app promotion information, and the like.

Then, the method proceeds to step S102 to execute, and calculates an association index between the target terminal and the first information set. In particular, the correlation index is expressed on a percentage basis. More specifically, the first information set includes x target terminal IDs, where x ≧ 1. Furthermore, the first information set further includes the k pieces of control information, and one target terminal ID corresponds to one or more pieces of control information, where k ≧ 1. Preferably, the association index is used to represent the weight of the target terminal in the first information set. Preferably, the association index is further used for indicating the degree of association between the target terminal and the first control information. In a preferred embodiment, the first information set is sorted based on the update time of the target terminal ID, the closer the target terminal ID is updated into the first information set, the greater the weight thereof, and accordingly, after the background server receives the first request information currently sent by the target terminal, the update time of the target terminal ID in the first information set is searched based on the target terminal ID to obtain the association index. Further, if the target terminal ID in the first information set corresponds to the first control information, the correlation index value is increased. Preferably, the update time is represented based on a time stamp.

Then, step S103 is executed to determine whether the correlation index is greater than a first threshold. In particular, the first threshold value and the correlation index are represented on the basis of the same metric unit, for example, if the correlation index is a percentage, the corresponding first threshold value is also in the form of a percentage. More specifically, the first threshold is a default value of the background server. Furthermore, the first threshold value can be generated according to user definition, and the user comprises a monitoring party corresponding to the background server and a user corresponding to the target terminal. Preferably, the first threshold is stored in the background server memory. In a preferred embodiment, the background server compares the association index of the target terminal and the first information set with a first threshold preset in a memory thereof, determines whether the association index is greater than the first threshold, and determines that the target terminal is strongly associated with the first information set if the association index is greater than the first threshold, that is, the determination result of step S103 is positive; otherwise, the determination result of the step S103 is negative, and further, if the determination result of the step S103 is positive, the process proceeds to step S104; if the determination result in the step S103 is negative, that is, the association index between the target terminal and the first information set is less than or equal to the first threshold, the process proceeds to step S105. Preferably, the first threshold is 90%, and those skilled in the art can also change more embodiments according to actual needs, which does not affect the technical content of the present invention.

Specifically, in step S104, if the association index is greater than the first threshold, first control information is sent to the target terminal. More specifically, the first control information includes installation package file information of the app. In a preferred example, after the user clicks app promotion information issued by the background server on the target terminal, the background server receives first request information requesting installation of the app sent by the target terminal, and if the finally calculated association index of the target terminal is greater than 90%, the installation package file of the app is fed back to the target terminal as the first control information. Further, the first control information further includes first counting invitation control information, which is used for recording subsequent processing conditions of the first control information on the target terminal.

Specifically, in step S105, if the association index is not greater than the first threshold, second control information is sent to the target terminal. More specifically, the second control information is stored in the first set of information or in a storage device associated with the first set of information. Preferably, the second control information is stored in the first information set. Preferably, the second control information is any control information in the first information set except the first control information, for example, after the backend server determines that the target terminal is weakly associated with the first control information based on the association index, the backend server randomly acquires any control information in the first information set except the first control information as the second control information and sends the second control information to the target terminal.

Further, the second control information further includes second counting invitation control information, which is used for recording subsequent processing conditions of the second control information at the target terminal.

Further, the second control information is any one or more of the other control information in the control information set corresponding to the target terminal ID in the first information set except the first control information, for example, after determining that the target terminal is weakly associated with the first control information, the backend server preferably obtains the second control information in the control information set corresponding to the target terminal. Further, the background server takes the control information with the highest association index with the target terminal except the first control information in the control information set as the second control information.

Further, the first control information, the second control information and/or the first information set are stored in a storage device, where the storage device includes any one or more of a memory, a background thread, a Flash disk, or a cloud storage device.

Those skilled in the art understand that, compared with the technical solution in step S104, the technical solution in step S105 may be understood as another determination result obtained after the determination is performed based on the association index, for example, a user sends first request information for installing app software to the backend server based on the target terminal, the backend server calculates the association index between the target terminal and the first information set after receiving the first request information, and sends the app software installation package to the target terminal as the first control information if the association index is greater than a first threshold; correspondingly, if the association index is smaller than a first threshold value, it is determined that the target terminal is weakly associated with the app software, and the other software information in the first information set is sent to the target terminal as second control information, which is a technical solution not adopted in the prior art, so that the background server can determine whether to respond to the first request information of the target terminal based on the target terminal ID and the association index, and further, if the determination result of the step S103 indicates that the target terminal is weakly associated with the first information set, it is preferable to send other information to the target terminal, and a most preferable solution for information push is generated through reasonable analysis of the user target terminal, instead of blindly satisfying any requirement of the user, thereby greatly optimizing an information push manner, and also optimizing user experience.

In a variation of this embodiment, in step S101, the background server may further passively receive first request information sent by the target terminal, for example, if the user knows that a premium game app wants to further download experience based on public praise marketing and other third party channels, the user enters a download page of the game app after inputting the name of the game app in the app store, and when the user confirms to download the game app, the user sends the first request information to the background server corresponding to the game app based on the current mobile terminal, and those skilled in the art understand that, compared with the technical solution of actively obtaining the first request information in step S101, the passive obtaining manner in this variation may attract the user' S attention to form the first request information based on public praise or other offline popularization manners without being promoted to the user in advance, the skilled person can also combine the active and passive modes according to actual needs, which does not affect the technical content of the present invention.

In a further variation of this embodiment, in the step S102, the association index indicates a degree of association between the first control information corresponding to the first request information and the target terminal, for example, if the target terminal has historically sent the first request information and has successfully activated the corresponding first control information, it is determined that the target terminal is weakly associated with the first control information corresponding to the first request information; further, if the target terminal has not sent the first request information historically or has not successfully activated the corresponding first control information although the first request information was sent, it is determined that the target terminal is strongly associated with the first control information corresponding to the first request information. Those skilled in the art understand that, if the target terminal has sent the first request information historically, the probability of activating the first control information corresponding to the first request information is higher, and if the first control information has been successfully activated by the target terminal, the degree of association between the target terminal and the first information set is low this time; on the contrary, if the target terminal has not sent the first request information historically, it may be basically determined explicitly that the purpose of sending the first request information by the target terminal this time is to obtain the first control information, and accordingly, in this case, the degree of association between the target terminal and the first information set is the highest.

In another variation of this embodiment, in step S102, the first information set includes one or more target terminals, and each target terminal corresponds to one or more control information at the same time, and each control information corresponds to a first threshold, and the backend server determines an association index of the target terminal with the first information set based on the first request information and the target terminal ID, for example, the target terminal corresponds to a control information set U ═ a, B, C, D } in the first information set, where a represents first control information, B represents second control information, C represents third control information, and D represents fourth control information, and accordingly, the first control information a corresponds to an association index a, the second control information B corresponds to an association index B, and the third control information C corresponds to an association index C, the fourth control information D corresponds to the association index D, after the background server receives first request information from the target terminal, the control information content corresponding to the first request information is judged, if the first request information corresponds to the first control information a, the association index a corresponding to the first control information a is obtained in the first information set, and then whether the association index a is larger than the first threshold value or not is judged.

In yet another variation of this embodiment, if the step S105 may be omitted, the background server does not send any feedback information to the target terminal after determining that the association index between the target terminal and the first information set is less than or equal to the first threshold based on the determination result of the step S103, so as to optimize the data processing amount of the background server, reduce the workload of the background server, and improve the operation speed of the background server.

Fig. 2 is a flowchart illustrating a control method for accurately identifying a target terminal, which is used for screening the target terminal to determine whether to send first control information to the target terminal according to a second embodiment of the present invention. Specifically, step S201 is first executed to receive first request information from the target terminal. More specifically, the first request information corresponds to the first control information, and includes request information requesting presentation of the first control information. Furthermore, a person skilled in the art may refer to the step S101 in the embodiment shown in fig. 1, which is not described herein again.

Then, the method proceeds to step S202 to execute, and calculates the association index based on the number of times that the target terminal appears in the first information set. Specifically, the occurrence number represents the number of times that the target terminal sends the first request information to the background server. More specifically, the occurrence number also represents the number of times that the target terminal sends the first request information to the background server within a period of time T. Furthermore, the occurrence number is stored in the first information set corresponding to the target terminal. Preferably, the background server obtains the occurrence number of the target terminal in the first information set based on the ID of the target terminal in the first information set. In a preferred embodiment, the number of occurrences of the target terminal ID in the first information set is greater, the weight value thereof is higher, the correlation index is also greater, accordingly, the first information set further includes a count information corresponding to the target terminal ID, the count information value corresponding to the target terminal ID in the first information set is increased by 1 every time the target terminal ID is updated, and further, the correlation index is increased by one scale value every time the count information value corresponding to the target terminal is increased by 1. Preferably, the scale value is 10%, for example, each time 1 is added to the count information, the association index between the target terminal and the first information set is increased by 10%, and those skilled in the art may also change further embodiments according to actual needs, which does not affect the technical content of the present invention.

Then, step S203 is executed to determine whether the correlation index is greater than a first threshold. Specifically, if the association index between the target terminal and the first information set is greater than the first threshold, the determination result in step S203 is affirmative; otherwise, the determination result of the step S203 is negative, and more specifically, if the determination result of the step S203 is positive, the step S204 is executed; if the determination result in the step S203 is negative, that is, the association index between the target terminal and the first information set is less than or equal to the first threshold, the process proceeds to step S205. Furthermore, a person skilled in the art may refer to step S103 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S204, if the association index is greater than the first threshold, first control information is sent to the target terminal. More specifically, the first control information includes installation package file information of the app. Furthermore, a person skilled in the art may refer to the step S104 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S205, if the association index is greater than the first threshold, second control information is sent to the target terminal. More specifically, the second control information is stored in the first set of information or in a storage device associated with the first set of information. Furthermore, a person skilled in the art may refer to step S105 in the embodiment shown in fig. 1, which is not described herein again.

In a variation of this embodiment, the step S202 further assists in calculating the correlation index of the target terminal and the first information set based on the first control information, and those skilled in the art understand that the number of occurrences of the target terminal in the first information set may correspond to a plurality of different control information, for example, the target terminal may occur 3 times in the first information set and respectively correspond to 3 different control information in the first information set, where only 1 is the first control information, the backend server preferably refines the correlation index of the target terminal and the first control information in the first information set based on a similarity determination formula F (target terminal ID, number of occurrences, first control information), for example, if the target terminal ID is recorded as empty in the first information set, judging that the target terminal never sends the first request information to the background server, so as to update the target terminal ID corresponding to the target terminal into the first information set and correspondingly endow an initial value of an association index; correspondingly, if the corresponding occurrence times of the target terminal ID in the first information set are not null, the request times of the target terminal for requesting the first control information from the background server are obtained, and therefore the association index of the target terminal and the first control information is calculated.

Those skilled in the art understand that, in this embodiment, the step S202 may be understood as a specific implementation of the step S102 in the embodiment shown in fig. 1, and it preferably calculates the degree of association between the target terminal and the first information set based on the number of occurrences of the target terminal in the first information set, so as to implement quantitative measurement of the association index, which is a technical solution not adopted in the prior art, and allows the background server to intuitively and effectively measure the degree of association between the target terminal and the first information set, especially the degree of association between the target terminal and the first control information set based on the number of occurrences of the target terminal in the first information set, so as to optimize the operation experience of the information publisher.

Fig. 3 is a flowchart illustrating a control method for accurately identifying a target terminal, which is used for screening the target terminal to determine whether to send first control information to the target terminal according to a third embodiment of the present invention. Specifically, step S301 is executed first, and first request information is received from the target terminal. More specifically, the first request information corresponds to the first control information, and includes request information requesting presentation of the first control information. Furthermore, a person skilled in the art may refer to the step S101 in the embodiment shown in fig. 1, which is not described herein again.

Then, the method proceeds to step S302 to execute, and calculates the association index based on the number of times that the target terminal appears in the first information set. Specifically, the occurrence number represents the number of times that the target terminal sends the first request information to the background server. More specifically, the occurrence number also represents the number of times that the target terminal sends the first request information to the background server within a period of time T. Furthermore, a person skilled in the art may refer to the step S202 in the embodiment shown in fig. 2, which is not described herein again.

Step S303 is then performed to determine whether the correlation index is greater than a first threshold. Specifically, if the association index between the target terminal and the first information set is greater than the first threshold, the determination result in step S303 is positive; otherwise, the determination result of the step S303 is negative, and more specifically, if the determination result of the step S303 is positive, the step S304 is executed; if the determination result in the step S303 is negative, that is, the association index between the target terminal and the first information set is less than or equal to the first threshold, the process proceeds to step S305. Furthermore, a person skilled in the art may refer to step S103 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S304, if the association index is greater than the first threshold, first control information is sent to the target terminal. More specifically, the first control information includes installation package file information of the app. Furthermore, a person skilled in the art may refer to the step S104 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S305, if the association index is greater than the first threshold, second control information is sent to the target terminal. More specifically, the second control information is stored in the first set of information or in a storage device associated with the first set of information. Furthermore, a person skilled in the art may refer to step S105 in the embodiment shown in fig. 1, which is not described herein again.

Then, the process proceeds to step S306, and determines whether the first control information is activated. Specifically, the background server performs the determination based on the feedback information sent by the target terminal. More specifically, the feedback information includes an installation use condition of the first control information or the second control information on the target terminal. Preferably, the manner of activating the first control information includes installing and/or using the first control information. In a preferred embodiment, after receiving the first request message sent by the target terminal, the background server establishes a communication connection with the target terminal and receives the feedback message sent by the target terminal, and if the feedback message indicates that the first control message is activated on the target terminal, the determination result in step S306 is positive; otherwise, the determination result of the step S306 is negative, and further, if the determination result of the step S306 is positive, the process proceeds to step S307, and if the determination result of the step S306 is negative, that is, the target terminal does not activate the first control information, the process ends.

Specifically, in the step S307, the number of occurrences of the target terminal in the first information set is reset based on first counting invitation control information. In a preferred embodiment, the first control information includes an application software installation package and corresponding first count invitation control information, and the target terminal feeds back the first count invitation control information to the backend server after successfully installing the application software, and those skilled in the art understand that the backend server calculates an association index between the target terminal and the first control information based on the number of occurrences of request information of the target terminal requesting the first control information in the first information set, and then updates the number of occurrences of the first information set corresponding to the target terminal while or after the backend server determines that the association index is greater than a first threshold and sends the first control information to the target terminal, and then feeds back the first count invitation control information based on the target terminal after the target terminal successfully activates the first control information to the target terminal in the first information set And updating the appearance times corresponding to the target terminal.

Further, the updating step includes "resetting the number of occurrences of the target terminal in the first information set based on the first count invitation control information", and the background server preferably clears the corresponding number of occurrences of the target terminal in the first information set based on the first count invitation control information. In a preferred embodiment, if the number of occurrences of the target terminal in the first information set is zero, it is determined that the target terminal has requested and successfully activated the first control information, the background server determines that the target terminal is weakly associated with the first control information, and sends second control information to the target terminal based on the determination result; if the corresponding occurrence number of the target terminal in the first information set is not zero, calculating the association index based on the occurrence number, and determining a size relationship between the association index and the first threshold to determine whether to send the first control information or the second control information to the target terminal, where a person skilled in the art understands that, in the technical scheme of this step, the background server obtains the ID of the target terminal based on the received first request information and establishes and/or updates the first information set, and for a target terminal that sends the first request information to the background server for the first time, if the ID of the target terminal corresponding to the target terminal is not initially recorded in the first information set, it may be understood that the initial value of the occurrence number of the target terminal in the first information set is null, and at this time, it is determined that the association index between the target terminal and the first information set is maximum, and the background server sends first control information corresponding to the first request information to the target terminal, simultaneously adds the ID and the occurrence times of the target terminal in the first information set, and updates the occurrence times corresponding to the ID of the target terminal based on the sent first counting invitation control information when the target terminal successfully activates the first control information.

In a variation of this embodiment, the step S307 further updates the first information set list and deletes the corresponding record of the target terminal based on the first count invitation control information, and those skilled in the art understand that the first information set is used to record target terminals that have sent the first request information but have not obtained corresponding first control information, or have not been successfully activated after obtaining the first control information, the first information set preferably excludes target terminals that have successfully activated the first control information, so that the stored content of the first information set is more simplified, the backend server can preliminarily determine the association index between the target terminal and the first information set as long as determining, based on the first request information, whether the target terminal is in the record of the first information set, and if the target terminal has a corresponding record in the first information set, then based on the association between the target terminal and the first information set The index finally determines the content of the control information sent to the target terminal, and the technical scheme of the variation greatly reduces the memory space occupied by the first information set by preferentially storing the information such as the occurrence frequency of the target terminal which does not successfully activate the first control information, shortens the calculation time of the correlation index, and improves the overall operation processing speed of the background server.

In another variation of this embodiment, the step S306 may be replaced by "determining whether the first control information or the second control information is activated", for example, if the target terminal receives the second control information, the backend server may also update the first information set by monitoring a processing condition of the target terminal on the second control information, comprehensively record a selection processing condition of the user on the related information, and optimize user experience.

Those skilled in the art understand that, in this embodiment, the step S306 and the step S307 may be understood as a specific implementation manner of the step S104 in the embodiment shown in fig. 1 or the step S204 in the embodiment shown in fig. 2, and preferably, the archived records in the first information set are updated by tracking a processing condition after the target terminal receives the first control information, so that a recording result of the target terminal in the first information set is effectively maintained in a highly accurate state all the time, which is beneficial for the backend server to perform subsequent operation processing on various types of request information of the target terminal.

Fig. 4 is a flowchart illustrating a control method for accurately identifying a target terminal, according to a fourth embodiment of the present invention, which is used for screening the target terminal to determine whether to send first control information to the target terminal. Specifically, step S401 is first executed to acquire n pieces of feature information of the target terminal based on the first request information. More specifically, the first request message is composed of an IP datagram and includes one or more feature messages capable of characterizing the identity information of the target terminal. Still further, the feature information includes specific fields in the IP datagram including at least a TTL field, a window size field, and the like. Preferably, the n pieces of feature information constitute a feature information set W. In a preferred embodiment, the background server extracts n pieces of feature information for characterizing the identity information of the target terminal from the IP datagram in the first request message to form the feature information set W. In another preferred embodiment, the first request information corresponds to the first control information, and further includes feature information of the target terminal, the feature information is used as unique identification information of the target terminal and is different from feature information of other target terminals, the feature information corresponds to the target terminal ID, the background server actively and/or passively receives the first request information sent from the target terminal, obtains the feature information of the target terminal by reading cookies stored in the target terminal, and establishes and stores a corresponding ID for the target terminal in a first database according to the feature information.

Then, the process proceeds to step S402, and calculates the feature probability C of the target terminal based on the following formula:

AX＝C

wherein A is a parameter vector of m pieces of feature information; and X is a characteristic value vector of m pieces of characteristic information, wherein m is more than or equal to 1 and less than or equal to n. Specifically, the feature probability C represents the feature similarity between the target terminal and a standard terminal. More specifically, the parameter vector a is used to represent the similarity between the m pieces of feature information and the standard feature information corresponding to the standard terminal. Further, the eigenvalue vector X may be understood as an adjustment coefficient of the parameter vector a. Preferably, the parameter vector a corresponds to the feature value vector X one to one, that is, the parameter vector of the ith feature information corresponds to the feature value vector of the ith feature information, and those skilled in the art understand that the one to one correspondence is favorable for performing weighting adjustment on the corresponding parameter vector based on the feature value vector, so that different parameter vectors obtain different weighting proportions, and the influence proportion of one or more feature information which can most embody the feature probability C in the calculation process is highlighted. In a preferred embodiment, the background server selects m pieces of feature information from the feature information set W to participate in the calculation, first selects a standard terminal, compares the m pieces of feature information with standard feature information corresponding to the standard terminal, obtains a similarity between the m pieces of feature information and the standard feature information to form a parameter vector a, then allocates an adjustment coefficient for each vector in the parameter vector a to form the feature value vector X, and obtains the feature probability C by multiplying the feature value vector X by the feature value vector X.

Next, step S403 is executed to obtain the corresponding target terminal ID from the first database based on the feature probability C. Specifically, the first database comprises one or more standard terminal IDs, and each standard terminal ID corresponds to a standard probability C' and one or more standard characteristic information respectively. More specifically, the first database is stored in the background server memory or an external storage device associated with the background server. In a preferred example, the first database stores 3 standard terminal IDs, which are respectively the standard terminal IDs under the ios system, the windows system and the android system, and the corresponding standard probabilities C 'and the plurality of standard feature information, and the background server compares the m feature information of the target terminal with the corresponding standard feature information of the 3 standard terminal IDs in the first database in sequence, calculates and obtains the corresponding feature probability C, finds that the values of the standard probabilities C' of the target terminal and the standard terminal IDs under the ios system are the closest, and then takes the standard terminal ID under the ios system as the target terminal ID.

And then step S404 is executed, and the number of times of the target terminal appearing in the first information set is obtained based on the target terminal ID. Specifically, the first information set includes one or more target terminal IDs and corresponding occurrence records. More specifically, the first information set further includes control information corresponding to the target terminal ID. Furthermore, one target terminal ID may correspond to a plurality of control information, respectively, and each of the control information corresponds to a record of occurrence times, respectively. In a preferred embodiment, each time the target terminal sends the first request information to the background server once, the occurrence frequency corresponding to the ID of the target terminal in the first information set is added by 1, and the background server can obtain the occurrence frequency of the target terminal in the first information set based on the ID information of the target terminal.

Next, step S405 is executed to calculate an association index between the target terminal and the first information set based on the occurrence number. Specifically, the association index of the target terminal and the first information set is the association index of the target terminal and the first control information in the first information set. Preferably, the number of occurrences has a correlation with the correlation index, and the greater the number of occurrences, the greater the correlation index representing the target terminal and the first information set. Those skilled in the art understand that, if the record of the target terminal ID in the first information set or the first information set corresponding to the first control information is null, which indicates that the target terminal never sends the first request information to the background server, the target terminal ID corresponding to the target terminal is updated into the first information set and is correspondingly assigned with an initial value of an association index, where the initial value of the association index is preferably much greater than the first threshold; correspondingly, if the corresponding occurrence times of the target terminal ID in the first information set are not null, acquiring the request times of the target terminal for requesting the first control information from the background server, thereby calculating the association index of the target terminal and the first control information; however, if the number of occurrences of the target terminal ID corresponding to the first control information in the first information set is zero, which indicates that the target terminal has requested the first control information and has successfully activated, the association index is preferably given a value much smaller than the first threshold.

Then, step S406 is executed to determine whether the association index is greater than a first threshold, specifically, if the association index of the target terminal and the first information set is greater than the first threshold, the determination result of step S406 is affirmative; otherwise, the determination result of the step S406 is negative, and more specifically, if the determination result of the step S406 is positive, the step S407 is executed; if the determination result in the step S406 is negative, that is, the correlation index between the target terminal and the first information set is less than or equal to the first threshold, the process proceeds to step S408. Furthermore, a person skilled in the art may refer to step S103 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S407, if the association index is greater than the first threshold, first control information is sent to the target terminal. More specifically, the first control information includes installation package file information of the app. Furthermore, a person skilled in the art may refer to the step S104 in the embodiment shown in fig. 1, which is not described herein again.

Specifically, in step S408, if the association index is greater than the first threshold, second control information is sent to the target terminal. More specifically, the second control information is stored in the first set of information or in a storage device associated with the first set of information. Furthermore, a person skilled in the art may refer to step S105 in the embodiment shown in fig. 1, which is not described herein again.

In a variation of this embodiment, if the standard probability C' is not included in the first database in step S403, the background server calculates and obtains the feature probability C of the target terminal corresponding to each standard terminal in the first database based on the formula in step S402, and then uses the standard terminal ID with the largest value of the feature probability C as the target terminal ID, so as to simplify the data amount required to be stored in the first database, and greatly improve the operating speed of the background server.

In yet another variation of this embodiment, the step S404 may be replaced by "acquiring the number of occurrences of the target terminal in the first information set based on the target terminal ID and control information". Specifically, the control information includes first control information and/or second control information, where the control information requested to be acquired by the current target terminal is the first control information, and the remaining control information corresponding to the target terminal ID is the second control information. For example, when the backend server corresponds to more than one occurrence count record in the first information set based on the target terminal ID, the backend server may further filter based on the first control information that is requested to be acquired by the target terminal this time, and acquire the occurrence count of the target terminal ID corresponding to the first control information in the first information set.

In yet another variation of this embodiment, a step "determining whether the first control information is activated" may be added after step S407 or step S408, specifically, the backend server performs the determination based on the feedback information sent by the target terminal. More specifically, the feedback information includes an installation use condition of the first control information or the second control information on the target terminal. Furthermore, a person skilled in the art may refer to the step S306 and the step S307 in the embodiment shown in fig. 3, which is not described herein again.
