And report more terminal numbers to the development side of the application program to cheat more popularization rewards, thereby bringing economic loss to the development side of the application program. Therefore, after a developer obtains a terminal that downloads its application program through a popularization channel and that is reported by a provider of the popularization channel, the developer generally determines whether the terminal reported by the popularization channel actually downloads the application program based on a login behavior, a login address, or an active state of the terminal using the application program, which are recorded by the developer.

The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented, for example, in sequences other than those illustrated or otherwise described herein.

Before formally describing the method and the device for detecting the downloading of the application program, the scene applied by the invention and the problems existing in the prior art are described with reference to fig. 1.
Fig. 1 is a schematic view of a scenario of application promotion in the prior art, as shown in fig. 1, in the prior art, after a developer of a program develops an application 1 (APP), the developer may issue the application 1 through the internet 3, for example, by a server 2 of the developer. A user who needs to use the application 1 is enabled to download the application 1 from the developer's server 2 through the path (1) in fig. 1 using the terminal 4 connected to the internet 3, and use the application 1 on the terminal 4.
In order to enable more terminals 4 to install the application 1 developed by the developer of the application 1, the developer of the application 1 may request the popularization channel 5 to popularize the application 1. The promotion channel 5 described herein may be an advertiser that causes other terminals to install the application 1 by publishing links in the internet content; alternatively, the promotion channel 5 may be software installed in the terminal and specially used for managing application programs, such as mobile phone assistant software and the like. As shown in fig. 1, after receiving the promotion request of the application 1, the provider of the promotion channel 5 can issue the application 1 in the internet, so that the terminal 4 accessing the internet 3 can download the application from the promotion channel 5 and use the application 1 on the terminal 4 through the path (2) in fig. 1. Thus, the promotion channel 5 realizes promotion of the application 1, so that the application 1 can be downloaded and used by more terminals through more channels.
In the prior art, a developer of an application 1 needs to pay and settle a payment to a provider of a promotion channel 5 according to the number of terminals 4 that use the promotion channel 5 to download its application 1. Under the driving of benefit, some bad suppliers of popularization channels 5 incorporate fake cheating terminals into terminals for actually downloading application programs through the action of fake terminals 4 for downloading application programs. And reports more terminals 4 to the developer of the application 1 to cheat more popularizing rewards, thereby bringing economic loss to the developer of the application 1. Therefore, the developer of the application 1 needs to determine whether the terminal actually downloads the application after acquiring the terminal of the application 1 downloaded through the popularization channel 5, which is reported by the provider of the popularization channel 5. With the prior art, when a developer detects whether the terminal 4 downloads an application program, it is necessary to analyze the behavior of the terminal 4 based on the service data of the application program 1 used by the terminal 4 in the server 2 corresponding to the application program 1, so as to determine whether the terminal 4 actually downloads the application program 1.
However, since the behavior of the terminal 4 is very easy to forge, especially, the terminal 4 using the android system, once the operating system authority is maliciously obtained, the operating system parameters of the terminal 4 can be arbitrarily modified, so that the behavior of the terminal 4 is forged, and the service data recorded in the server 2 may come from the forged terminal 4 instead of the terminal actually downloading the application program 1, which further causes that a developer cannot accurately detect whether the application program is downloaded by the terminal.
Therefore, the invention provides a method and a device for detecting the downloading of an application program, aiming at the problems in the prior art, and when the terminal needs to detect whether the target application program is downloaded or not, SDK data uploaded to a server by the terminal is obtained. And determining whether the terminal downloads the target application program according to the attribute information of the terminal in the SDK data. The method and the device for detecting whether the terminal downloads the target application program are realized based on the application program, and the SDK data are directly uploaded to the server by the terminal and are not easy to tamper and forge by a popularization channel of a third party, so that a developer of the application program can more accurately detect whether the terminal downloads the application program based on the SDK data.
Specifically, fig. 2 is a schematic structural diagram of a system to which the method for detecting downloading of an application program according to the present invention is applied, where the system shown in fig. 2 further includes, on the basis of the system shown in fig. 1: a server 6 for receiving and storing SDK data including terminal attribute information transmitted from the terminal 4 via the internet. The server 2 of the developer of the application 1 can acquire SDK data of the terminal 4 in the server 6 through the internet. And for each of the terminals 4 of the system shown in fig. 2, after determining the attribute information of the terminal, the attribute information is transmitted to the server 6 as SDK data.
The following details of the method for detecting the downloading of the application program in this embodiment are described with reference to fig. 3, fig. 4 and fig. 5, and the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. The execution subject of the method shown in fig. 3 and fig. 4 may be the server 2 shown in fig. 2, and the execution subject of the method shown in fig. 5 may be any terminal 4 shown in fig. 2.
Fig. 3 is a flowchart of an embodiment of a method for detecting downloading of an application program according to the present invention, as shown in fig. 3, where the method provided in the embodiment includes:
s101: determining SDK data sent to a server by a terminal; wherein the SDK data comprises attribute information of the terminal.
Specifically, the present embodiment is applied to the server 2 of the developer of the application 1 shown in fig. 2 detecting whether the terminal 4 actually downloads the target application, the server 2 first determines SDK data sent from the terminal 4 to the server 6 in S101. Wherein, the server 6 and the server 2 may be different servers deployed in the internet; alternatively, the server 6 and the server 2 may perform different functions from each other by the same server.
Alternatively, the terminal 4 determined in this embodiment may be reported by the promotion channel 5, and the terminal 4 of the application 1 is downloaded through the promotion channel 5. At this time, the server 2 of the developer of the application 1 needs to detect whether the terminal 4 has actually downloaded the application 1 through the promotion channel 5.
Alternatively, in order to enable the terminal to actively acquire the SDK data and send the SDK data to the server 6, a developer of the application 1 may add an instruction to the application 1 to enable the terminal to report the SDK data by itself, for example, in the form of a plug-in when the application is developed. The terminal downloaded with the application program 1 can acquire the attribute information of the terminal according to the indication of the plug-in unit, and then add the attribute information into the SDK data and send the SDK data to the server 6.
Alternatively, the terminal may send the SDK data to the server 6 at preset time intervals, for example, the terminal sends the SDK data to the server 6 in the early morning every day when idle, and the server 6 stores the received SDK data. When the server 2 acquires the SDK data of the terminal 4 in the server 6, it is the SDK data that the terminal has uploaded to the server 6 that should be acquired.
S102: and detecting whether the terminal downloads the target application program according to the SDK data.
Subsequently, the server 2 may detect whether the terminal downloads the target application, i.e., the application 1 in the example shown in fig. 2, according to the attribute information of the terminal in the SDK data acquired in S101. The attribute information of the terminal provided in this embodiment specifically includes one or more of the following: the hardware information, software information, security environment information, and network environment information of the terminal 4 are described below, respectively.
The hardware information includes: identification Information (ID) of the terminal, international Mobile Equipment Identification (IMEI) of the terminal, medium access control address (Media Access Control Address, MAC) of the terminal, user identity (Subscriber Identification Module, SIM) card, and information such as model number, production lot of the terminal when the terminal is a mobile phone or a tablet computer. The hardware information of the terminal cannot be forged due to the uniqueness of the hardware information, so that the terminal reports the hardware information to the server through the SDK data, and the terminal can be uniquely identified when judging whether the terminal downloads the application program through the popularization channel or not.
The software information includes: the version of the operating system used by the terminal and whether the terminal has specified software installed. For example, the version of the operating system may be a version of an iOS operating system or an android operating system. From the aspect of security, the terminal may report to the server through the SDK data whether the terminal installs the designated software, for example: if a certain piece of tampered software can be used for modifying the network address of the terminal, after the terminal reports the tampered software to the server, the terminal can be enabled to be modified due to the existence of the tampered software when judging whether the terminal downloads the application program through the popularization channel or not, so that the terminal can be judged that the application program is not actually downloaded through the popularization channel. Or, for example, the designated software refers to chat software, weather software, or shopping class software that is commonly used, and considering that a terminal, if it installs the designated software, may be considered as a terminal actually used by a user or may be referred to as an "active user". When judging whether the terminal downloads the application program through the popularization channel or not later, the terminal confirms that the downloading behavior of the terminal is real, but not the false cheating downloading behavior of the abandoned terminal or the idle terminal.
The secure environment information includes: whether the rights of the operating system of the terminal are tampered with, the act of tampering with the operating system rights may be referred to as "root". The root refers to the highest management authority in the operating system, after the operating system of the terminal is subjected to the root, the root is not constrained by various management mechanisms of the operating system, and various operating system parameters of the terminal can be modified by a user. Therefore, in this embodiment, the terminal needs to report the information about whether the terminal is root through the SDK data, and when judging whether the terminal downloads the application program through the popularization channel later, consider that the behavior of downloading the application program through the popularization channel for the terminal after the root may be a false cheating behavior.
The network environment information includes: an internet protocol (Internet Protocol, abbreviated as IP) address of the terminal accessing the internet, whether the IP address is tampered with, whether the terminal uses a virtual private network (Virtual Private Network, abbreviated as VPN), etc. The IP address used by the terminal can be used for judging whether the terminal downloads the application program through the popularization channel, and if the IP address of the terminal is artificially modified, the behavior that the terminal downloads the application program through the popularization channel by using the IP address can be judged to be false cheating behavior.
Alternatively, in one possible implementation manner of S102 of this embodiment, the server may specifically determine, according to the attribute information of each terminal through a machine learning algorithm, whether the terminal downloads the target application according to the similarity degree with the attribute information of the terminal that does not download the target application.
For example, if the attribute information of the terminal specifically includes the security environment information, the attribute information of the terminal acquired in S101 may be: the terminal is shot, the machine learning model in the machine learning algorithm is obtained by learning whether the terminal without downloading the target application program is shot or not, so that the server in S102 can determine that the terminal does not download the target application program by comparing the shot safety environment information of the terminal acquired in S101 with the safety environment information of the terminal without downloading the target application program in the machine learning model, if the two safety environment information are identical, and if the two safety environment information are different, the terminal downloads the target application program. As another example, if the attribute information of the terminal includes hardware information, software information, security environment information, and network environment information, the attribute information of the terminal acquired in S101 may be: the MAC address of the terminal, the operating system of the terminal, the root of the terminal, and the IP address of the terminal, the server may also compare the acquired attribute information of the terminal with the security environment information of the terminal in which the target application is not downloaded in the machine learning model in S102, since the machine learning model determines whether the terminal downloads the target application program according to the similarity between the MAC address of the terminal, the operating system of the terminal, the root of the terminal and the IP address of the terminal, which are not downloaded with the target application program.
Wherein the machine learning algorithm may use commonly used techniques such as: a K-Nearest Neighbor algorithm (KNN), a support vector machine (Support Vector Machine, SVM) or a deep learning algorithm, and the like. After the server can conduct feature learning in advance through the attribute information of the terminal which does not download the target application program and obtain a machine learning feature model, the attribute information of the terminal to be detected is subjected to feature extraction through a machine learning algorithm and is compared with the machine learning feature model, and whether the attribute information of the terminal to be detected downloads the target application program is determined according to the output similarity degree. The algorithm implementation and principle of the machine learning detection can refer to the prior art, and the invention is not particularly limited.
In summary, in the method for detecting downloading of an application program provided in this embodiment, when it is required to detect whether a terminal downloads a target application program, SDK data uploaded to a server by the terminal is obtained. And determining whether the terminal downloads the target application program according to the attribute information of the terminal in the SDK data. The attribute information of the terminal in this embodiment includes: hardware information, software information, security environment information and network environment information, the attribute information based on the terminal characteristics is difficult to tamper and forge, and compared with a detection method based on terminal behaviors in the prior art, the detection method based on the terminal behaviors has higher accuracy and uniqueness. In addition, since the SDK data used when the terminal is used for detecting whether the terminal downloads the target application program is realized based on the application program, the SDK data is directly uploaded to the server by the terminal, and the popularization channel of the third party is not easy to tamper and forge, so that a developer of the application program can more accurately detect whether the terminal downloads the application program based on the SDK data.
Fig. 4 is a flowchart illustrating an embodiment of a method for detecting downloading of an application program according to the present invention. The embodiment shown in fig. 4 provides a specific application method for detecting whether the terminal downloads the target application program on the basis of the embodiment shown in fig. 3, wherein when the method is applied to the system shown in fig. 2, the server 2 of the developer of the application program 1 can evaluate the popularization channel 5. Specifically, as shown in fig. 3, the method provided in this embodiment includes:
s201 the method comprises the following steps: and determining a plurality of terminals of the target application program which are reported by the suppliers of the popularization channels and are downloaded through the popularization channels.
Specifically, in order to evaluate the promotion channel 5, the server 2 first determines a plurality of terminals 4 through which the targeted application program is downloaded via the promotion channel 5, which are reported by the provider of the promotion channel 5. The target application is an application designated by a developer corresponding to the server 2, that is, the application 1 in fig. 2.
Alternatively, the promotion channel 5 shown in fig. 2 may send a terminal list to the server 2 at preset time intervals; alternatively, the promotion channel 5 may transmit the terminal list to the server 2 when settling the promotion of the application 1 with the server. The terminal list includes identification information of the plurality of terminals 4, for example, information such as serial numbers of the terminals, time for downloading the target application program through the popularization channel 5, and the like, so that after the server 2 determines the plurality of terminals 4 according to the terminal list, it determines whether the plurality of terminals 4 download the application program 1 through the popularization channel 5 through subsequent steps.
S202: acquiring SDK data sent to a server by the plurality of terminals; the SDK data includes attribute information of the terminal.
Specifically, as shown in fig. 2, after the server 2 determines the plurality of terminals 4 reported by the promotion channel 5 through S101, SDK data sent from the plurality of terminals 4 to the server 6 is acquired. The manner in which the server 2 acquires the SDK data from the server 6 may refer to S101, except that the SDK data of the plurality of terminals 4 are acquired in S202.
S203: and evaluating the popularization channels according to the SDK data of the plurality of terminals.
Subsequently, the server 2 as shown in fig. 2 evaluates the promotion channel based on the SDK data of the multi-terminal 4 acquired from the server 6 in S102.
Alternatively, in S103, the server 2 may determine whether the plurality of terminals 4 have downloaded the application 1 from the promotion channel 5 through attribute information of the plurality of terminals 4, and evaluate the promotion channel according to the proportion of the cheating terminals among the plurality of terminals 4. The cheating terminal refers to a terminal which is reported by a provider of a popularization channel in S101 and downloads the application program 1 through the popularization channel, but the terminal does not actually download the application program 1 through the popularization channel.
Optionally, the evaluation of the promotion channels in this embodiment may be to classify the promotion channels, for example, classifying the promotion channels into a high-quality channel, a suspected channel and a risk channel. And after the popularization channel is evaluated, the evaluation result can be pushed to relevant management personnel of the application program. Therefore, the manager can acquire the evaluation result of the popularization channel, and decide whether to continue entrusting the popularization channel to popularize the application program according to the evaluation.
Further, on the basis of the embodiment shown in FIG. 3 described above, the invention also provides a specific implementation method for evaluating the popularization channel, wherein the step S203 specifically comprises the following steps:
s2031: determining the duty ratio of cheating information included in the attribute information of the plurality of terminals; the cheating information comprises attribute information of a terminal which does not download the target application program through the popularization channel.
S2032: and evaluating the popularization channel according to the occupancy ratio of the cheating information.
Specifically, in the specific implementation method provided in this embodiment, the server as the execution subject of this embodiment first determines, through S2031, the occupancy rate of the cheating information included in each attribute information according to the attribute information in the SDK data of the plurality of terminals, and then evaluates, through S1032, the popularization channel according to the occupancy rate of the cheating information in all the attribute information.
Optionally, in this embodiment, the server may perform calculation of a ratio of the cheating information to each of the attribute information of all the plurality of terminals, and specifically calculate, in sequence, the ratio of the cheating information included in each of the attribute information of the plurality of terminals. For example, after acquiring the SDK information of 1000 terminals, the server processes each attribute information in the SDK information of 1000 terminals, respectively. The ratio of the cheating information in the hardware information of 1000 terminals, the ratio of the cheating information in the software information of 1000 terminals, the ratio of the cheating information in the security environment information of 1000 terminals and the ratio of the cheating information in the network environment information of 1000 terminals can be respectively determined. And finally, normalizing the duty ratio of the obtained cheating information of the four attribute information to obtain the duty ratio of the cheating information included in the attribute information of the plurality of terminals. Optionally, one possible implementation manner of the normalization processing described in this embodiment is that a value obtained by adding the ratios of the cheating information in the four attribute information is used as a total ratio of the cheating information included in the attribute information of the plurality of terminals; alternatively, in another possible implementation manner of normalization processing, the four attribute information may be given different weights and then added in a weighted manner, for example, software information capable of evaluating the popularization channel more accurately is given a larger weight, and hardware information is given a smaller weight and added.
Alternatively, in the above-described embodiment, the duty ratio of the cheating information included in each attribute information may be calculated by means of machine learning. For example, the server may determine whether the attribute information is the cheating information according to the similarity degree of each attribute information and the cheating information through a machine learning algorithm, thereby determining the duty ratio of the cheating information included in each attribute information. The server can acquire a machine learning model according to the training of the cheating information, judge each attribute information according to the machine model, determine whether the attribute information is the cheating information according to the similarity degree of each attribute information and the cheating information, and determine the duty ratio of the cheating information. For example, machine learning algorithms that can be used in the present embodiment include, but are not limited to: the principle of classifying and identifying whether the attribute information is cheating information by using a K-Nearest Neighbor algorithm (KNN), a support vector machine (Support Vector Machine, SVM) or a deep learning algorithm and the like can refer to the prior art, and is not repeated. More specifically, in this embodiment, the classification and judgment can be performed on whether the attribute information is the cheating information by using an iterative decision tree algorithm (Gradient Boosting Decision Tree, GBDT) algorithm machine learning algorithm.
For example: the server firstly acquires cheating information of 500 terminals which do not download application programs through a popularization channel, wherein the cheating information comprises four attribute information of hardware information, software information, security environment information and network environment information of the 500 terminals. The server learns the cheating information of the 500 terminals through the GBDT algorithm to obtain a GBDT weight calculation model, wherein the GBDT weight calculation model comprises the characteristics of the cheating information of the 500 terminals. Then, when determining whether the attribute information of the terminal is the cheating information in S2031, the server performs feature extraction on the attribute information of the terminal through the trained GBDT weight calculation model including the characteristics of the cheating information, and determines whether the attribute information to be determined is the cheating information after performing comparison. In this embodiment, the algorithm principle and implementation manner of applying the GBDT algorithm to the classification and identification can refer to the application of the GBDT algorithm in the classification and identification in the prior art, the cheating information is identified as a training sample, then the training is performed through the GBDT algorithm, and the sample to be identified is used for identification to output whether the sample to be identified is a cheating sample, so that the principle is not repeated. For example: the software information in which the tampered software is installed in the attribute information may be marked as 1, and the software information in which the tampered software is not installed in the attribute information may be marked as 0. After the GBDT weight calculation model is obtained through learning the information of 500 terminals, the attribute information marked as 1 to be identified is sent into the GBDT weight calculation model for classification calculation, and the GBDT algorithm is not limited in detail.
Further, after the server determines the ratio of total cheating information in all attribute information of the plurality of terminals through S2031, the quality evaluation level of the corresponding popularization channel is determined continuously through S2032 according to the range of the numerical value of the ratio of the cheating information; wherein, the quality evaluation grade at least comprises: the range of the numerical value of the duty ratio of the cheating information corresponds to the quality evaluation grade one by one; and thereby, the popularization channel is evaluated according to the determined quality evaluation grade.
For example, in a specific implementation of this embodiment, the threshold value may be set to 0.7 between the high-quality channel and the suspected channel of the quality evaluation level, and the threshold value may be set to 0.9 between the suspected channel and the risk channel. Determining that the evaluation level of the popularization channel is a risk channel when the ratio value of the cheating information determined in the S1031 is larger than or equal to 0.9; when the proportion value of the cheating information is smaller than 0.9 and larger than 0.7, determining the evaluation grade of the popularization channel as a suspected channel; when the proportion value of the cheating information is smaller than 0.7, the evaluation grade of the popularization channel is determined to be a high-quality channel.
In summary, in the method for detecting downloading of an application program provided in this embodiment, after a popularization channel reports that a plurality of terminals download the application program through the popularization channel, SDK data including terminal attribute information uploaded by the plurality of terminals to a server is obtained. And determining the proportion of terminals actually downloading the application program through the popularization channel in the plurality of terminals according to the attribute information of the terminals in the SDK data so as to evaluate the popularization channel of the application program. Therefore, the popularization channel for popularizing the application program can be evaluated, so that a developer of the subsequent application program can determine whether the popularization channel can be continuously entrusted for popularizing the application program through the evaluation result of the popularization channel. In addition, since the terminal attribute information used when evaluating the popularization channel is based on the behavior of actually using the terminal by the user, the forging and tampering cost is high; meanwhile, the SDK data used in the embodiment is realized based on the application program, and the popularization channel of the third party is not easy to tamper and forge. In addition, the popularization channel evaluation method provided by the embodiment does not need to rely on service data of an application program, and only starts with attribute information of equipment, so that portability is high, and popularization and use cost can be saved. In conclusion, the embodiment can enable the server to judge whether the terminal downloads the application program through the popularization channel more accurately and safely, and finally enable the server to accurately evaluate the application program popularization channel.
Fig. 5 is a flow chart of an embodiment of a method for detecting downloading of an application program according to the present invention, where an execution body of the embodiment may be any terminal in the system shown in fig. 2, and as shown in fig. 5, the method provided in the embodiment includes:
s301: the terminal determines SDK data, wherein the SDK data comprises: and the SDK data are used for evaluating the popularization channel of the target application program.
Specifically, the present embodiment is applicable to a system as shown in fig. 2, which is executed by any one of the at least one terminal 4. Wherein the terminal 4 first determines attribute information of the terminal through S301 and serves as SDK data to transmit the SDK data to the server 6 through the subsequent steps.
Optionally, attribute information of the terminal in this embodiment includes: hardware information, software information, security environment information and network environment information of the terminal. For the specific content of the attribute information, reference may be made to the description in the embodiment shown in fig. 3, and no further description is given.
Optionally, in one possible implementation manner of S301, in order to enable the terminal to actively acquire and send the SDK data to the server, a developer of the application program may add an instruction to the application program, where the instruction exists in the form of a plug-in, to enable the terminal to report the SDK data by itself, when the application program is developed. The method shown in fig. 5 is executed at intervals of preset time according to the indication of the plug-in after the terminal installs the application program, for example, the terminal determines SDK data of the terminal and sends the SDK data to the server when the terminal is idle, for example, in the early morning time of day according to the indication of the plug-in.
Or, alternatively, in another possible implementation manner of S301, after the terminal downloads the target application program for the first time, the terminal performs a flow as shown in fig. 5, that is, determines the SDK data and sends the SDK data to the server.
S302: and the terminal sends the SDK data to a server.
Subsequently, in S302, the terminal transmits the SDK data determined in S301 to the server. Thus, the system shown in fig. 2 can be applied, so that after the server 6 receives and stores the SDK data transmitted from the terminal 4, the server 2 can acquire the SDK data of the terminal 4 from the server 6 when the terminal 4 detects whether to download the application 1.
In summary, the method for detecting the download of an application program provided in this embodiment can be applied to a system as shown in fig. 2, and after determining SDK data including attribute information of a terminal 4 for the terminal 4 that downloads the application program 1, the SDK data is sent to a server 6. So that the server 2 can acquire the SDK data of the terminal 4 from the server 6 and detect according to the attribute information of the terminal 4 in the SDK data when detecting whether the terminal 4 downloads the application 1 later. Therefore, in the method for detecting the download of the application program provided in the embodiment, since the SDK data sent from the terminal to the server by the embodiment is forged and tampered by a third party, the cost is high; meanwhile, the SDK data used in the embodiment is realized based on the application program, so that the popularization channel of the third party is not easy to tamper and forge. In addition, in the method provided by the embodiment, the terminal can actively acquire the information, the server is not required to passively detect the attribute information of the terminal when the server needs to detect whether the terminal 4 downloads the application program, and the detection efficiency when detecting whether the terminal downloads the application program is also improved.
