It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some but not all of the relevant aspects of the present invention are shown in the drawings.
Example one
Fig. 1 is a flowchart of an apparatus identifier determining method according to an embodiment of the present invention, which is applicable to how to determine an apparatus identifier of an application program, and is particularly applicable to solving a problem that tracking of a user or a service and the like cannot be performed based on an apparatus identifier because the application program developed based on an IOS operating system has no apparatus identifier. The method may be performed by the device identifier determining apparatus/server provided in the embodiment of the present invention, and the apparatus may be implemented in software and/or hardware, and the apparatus may be configured on a server (server).
Referring to fig. 1, the method specifically includes:
and S110, receiving data information reported by the application program, wherein the data information comprises a user identifier and equipment characteristic data acquired by the application program.
An application program refers to a computer program that is developed and run on an operating system to accomplish a specific task or tasks, and may be configured in a mobile device to provide services to a user. The application program can be developed based on the IOS operating system and configured in a mobile device (such as an apple phone, an Ipad or a smart watch) running the IOS operating system; or an application program developed based on the android operating system, configured in a mobile device running the android operating system, or the like. In this embodiment, the application program is preferably an application program developed based on the IOS operating system.
The data information refers to information acquired when the application program is started, and can include user identification and device characteristic data acquired by the application program; the user identifier is used to uniquely identify or authenticate the user identity, and may be an account number of the user logging in the application program, such as a user name or a user ID. Optionally, the user identifier is a user ID. The device feature data refers to feature data of the mobile device collected when the application program is started. Illustratively, the device characterization data may include the following: the advertisement identifier of the operating system, the device storage capacity, the memory capacity, the operating system version, the provider identifier of the operating system, the device name, and the like may further include at least one of a model, a network system, a scheduling rate, and a user log, and the like. For a mobile device running an IOS operating system, the advertisement Identifier of the operating system is IDFA (Identifier For advertisement, IDFA) of the IOS; the Vendor Identifier of the operating system is the IDFV (Identifier For Vendor) of the IOS. Optionally, the data information may further include an application name and the like.
Specifically, when the application program is started, the device characteristic data of the device where the application program is located can be collected, the user ID is obtained, then the user ID and the device characteristic data are used as data information, and then the data information is requested to be reported to the server through the http network, and the server receives the data information reported by the application program.
Optionally, in order to ensure the reliability of communication between the application program and the server, the application program may also encrypt the data information by using a public key in the asymmetric key pair of the server, and then report the encrypted data information to the server; the server receives the encrypted data information reported by the application program, and can decrypt the encrypted data information by adopting a private key in the asymmetric key pair so as to obtain the data information of the application program.
It should be noted that the application in this embodiment may be an application for identifying a location of a device, such as an application installed by a user for the first time. It is also possible that the device identification has been previously determined and then needs to be confirmed again, such as the user uninstalling an application that is reinstalled after the uninstallation.
And S120, if the historical data of the user identifier is locally stored, determining the device identifier of the application program according to the device characteristic data and the historical data.
In this embodiment, local refers to local at the server; the historical data of the user identifier can be device characteristic data in data information reported by different application programs stored by the server when the user logs in different application programs by the same user ID in the past; the device characteristic data in the data information reported by the application program stored by the server can also be stored by the user who previously logs in the same application program by using the same user ID. The historical data can be stored in a database local to the server, a log file and the like.
Optionally, an index table of the correspondence between the user identifier, the application name, and the device feature data may be maintained in the local database of the server. Specifically, after receiving data information reported by any application program, the server may query the index table according to a user identifier in the data information, and if the index table has the user identifier, it is determined that the historical data of the user identifier is stored in the local database of the server.
For example, it may be determined whether historical data of the user identifier is stored locally by the following method, specifically including: and matching the user identification with the locally stored user identification data of other application programs, and determining whether historical data of the user identification is locally stored according to a matching result. Specifically, after receiving the data information reported by any application program, the server may search in the local database according to the name of the application program in the data information, and if the matched application program name is not searched; the user identifier may be matched with user identifier data of other application programs stored in the local database, and if the user identifier exists in the local database, it is determined that the history data of the user identifier is locally stored. Here, the application is an application that reports data information to the server for the first time, and may be an application newly installed by the user. In addition, the server stores the names of a plurality of application programs with the same user identifier, but the plurality of application programs with the same user identifier share one historical data, and the historical data is the device characteristic data reported by the application program logged in by the user identifier and received by the server for the last time.
The Device Identifier of the application refers to a Unique Identifier that enables tracking of a user, a service, or the like, and may be a Unique Device Identifier (UDID).
Specifically, if the server finds the user identifier data matched with the user identifier locally, it is determined that the historical data of the user identifier is stored locally, and the server may determine the device identifier of the application program according to the device feature data in the data information reported by the application program this time and the historical data. For example, the device characteristic data in the data information reported by the application program at this time may be subjected to similarity matching with the historical data, and if the matching result is greater than or equal to a preset value and the application program is an application program newly installed by a user, the device identifier of another application program associated with the historical data may be used as the device identifier of the application program, and the identifier is sent to the application program, and meanwhile, the historical data associated with the user identifier may be updated by the device characteristic data reported by the application program at this time. If the application program is the application program which is uninstalled and reinstalled by the user and the matching result is greater than or equal to the preset numerical value, the device identifier of the application program is not changed, and the device characteristic data reported by the application program at this time can be used for updating the historical data associated with the user identifier.
It should be noted that, in this embodiment, if the matching result is greater than or equal to the preset value, it indicates that multiple application programs are configured on the same mobile device, and the device identifiers obtained by the same user identifier on the same mobile device through the multiple application programs are the same; and the device identifier of the same application program is unchanged after the application program is uninstalled and reinstalled.
And if the server does not locally find the user identification data matched with the user identification, determining that the server does not locally store the historical data of the user identification. For example, after receiving the data information reported by the application program, the method may further include: if the fact that historical data of the user identification are not stored locally is determined, an equipment unique identifier is created according to the user identification; the user identifier is bound to the device unique identifier and stored locally.
Specifically, if the server does not locally find the user identifier data matched with the user identifier, it is determined that the server does not locally store the historical data of the user identifier. At this time, the server may create a device Unique Identifier (UUID) based on the user Identifier, use the device Unique Identifier as the device Identifier of the application program, and store the user Identifier, the device Unique Identifier, and the application program in a local database in an associated manner.
According to the technical scheme provided by the embodiment of the invention, the server receives the data information reported by the application program, and determines the equipment identifier of the application program according to the historical data and the equipment characteristic data included by the data information when the historical data of the user identifier included by the data information is determined to be locally stored. The scheme provides a new idea for determining the equipment identifier of the application program, and can solve the problem that the application program developed based on the IOS has no equipment identifier, so that the tracking of users or services and the like can not be carried out based on the equipment identifier; the device identification of the application program can be determined, and a foundation is laid for tracking users or services and the like based on the device identification.
Example two
Fig. 2 is a flowchart of a device identifier determining method according to a second embodiment of the present invention, and this embodiment further explains determining a device identifier of an application according to device feature data and historical data based on the above embodiment. Referring to fig. 2, the method specifically includes:
s210, receiving data information reported by the application program, wherein the data information comprises a user identifier and device characteristic data collected by the application program.
And S220, if the historical data of the user identification is locally stored, comparing the characteristic value associated with the equipment characteristic data with the characteristic value associated with the historical data, and determining a similarity value according to the comparison result.
In this embodiment, each item in the device feature data is used as a feature data, and a value of each feature data is a feature value of the feature data. For example, the value of the characteristic data of the storage capacity may be 64G, where 64G is a characteristic value associated with the storage capacity. The similarity value is used for representing the similarity degree between the upper device characteristic data reported by the application program this time and the historical data of the same user identification.
Specifically, after determining that the historical data of the user identifier is locally stored, the server may compare the name of each item of feature data of the device feature data reported this time by the application with the name of each item of feature data of the device feature data in the historical data; and then, comparing the characteristic values associated with the characteristic data with the same name of the characteristic data in sequence, and determining the similarity value between the two according to the comparison result.
For example, determining the similarity value according to the comparison result may include the following steps:
A. obtaining a characteristic value weight value corresponding to the same characteristic value according to the comparison result to obtain a characteristic value weight value set;
the characteristic value weight value refers to the proportion of the characteristic data associated with the characteristic value in the equipment characteristic data. The eigenvalue weight value set refers to a set consisting of at least one eigenvalue weight.
Specifically, the feature value weight value of the feature data associated with the same feature value can be obtained according to the comparison result of the feature value associated with the device feature data and the feature value associated with the historical data; and then comparing the characteristic value weight values of the two characteristic values, and forming a characteristic value weight value set by using each characteristic value weight value with the same characteristic value weight value according to a comparison result.
B. And determining a similarity value by accumulating the weight values of all the characteristic values in the characteristic value weight value set.
Specifically, the sum operation is performed on each feature value weight value in the feature value weight value set, so as to obtain a similarity value.
And S230, if the similarity value is equal to or greater than the similarity threshold value, acquiring the equipment unique identifier associated with the user identifier from the local.
In this embodiment, the similarity threshold is a lower limit of the degree of similarity between the preset device feature data and the historical data of the same user identifier, and may be modified according to an actual situation. Preferably, according to a large amount of practice and calculation summary, the threshold of similarity is 55, which is a threshold for accurately identifying whether applications with the same subscriber identity are allocated to the same mobile device. The device unique identifier may be a device unique identification UDID or a UUID.
Specifically, if the similarity value between the device feature data and the historical data of the same user identifier is equal to or greater than the similarity threshold value, it may be determined that the user logs in an application program with the same user identifier using the same mobile device, such as the same application program or different application programs, and then the device unique identifier associated with the user identifier may be obtained from the local database according to the user identifier, and then step S240 is executed to use the device unique identifier as the device identifier of the application program and send the device unique identifier to the application program.
If the similarity value is smaller than the similarity threshold value and the same application program with the same user identifier is determined according to the historical data, the user can be determined to log in the application program by adopting different mobile user equipment, and an equipment unique identifier can be created again; and binding the user identifier with the unique identifier of the equipment, and replacing the historical data with the reported equipment characteristic data. It may also be determined whether to recreate a device unique identifier, etc., depending on how often the user logs into the application using different devices.
If the similarity value is smaller than the similarity threshold value and different application programs with the same user identification are determined according to historical data, the user can be determined to log in different application programs by adopting different mobile user equipment, and an equipment unique identifier can be created again; and binding the user identifier with the device unique identifier so that when the user logs in other application programs or the application program by adopting the mobile device, the device identification of the application program is directly determined. The same user identification, login of different mobile devices, may be distinguished based on the device unique identifiers of the different mobile devices being different.
In this embodiment, if the matching result is greater than or equal to the preset value, it indicates that the user logs in the application program with the same user identifier using the same mobile device, for example, the same application program may be used, or different application programs may be used. The device identifications of the same user identification obtained on the same mobile device by a plurality of application programs are the same; and the device identifier of the same application program is unchanged after the application program is uninstalled and reinstalled.
And S240, taking the device unique identifier as the device identification of the application program, and sending the device unique identifier to the application program.
For example, after the device unique identifier is used as the device identifier of the application program and the device unique identifier is sent to the application program, the method may further include: and updating the historical data associated with the user identification by adopting the device characteristic data reported by the application program this time.
According to the technical scheme provided by the embodiment of the invention, the server receives the data information reported by the application program, and determines the equipment identifier of the application program according to the historical data and the equipment characteristic data included by the data information when the historical data of the user identifier included by the data information is determined to be locally stored. The scheme provides a new idea for determining the equipment identifier of the application program, and can solve the problem that the application program developed based on the IOS has no equipment identifier, so that the tracking of users or services and the like can not be carried out based on the equipment identifier; the device identification of the application program can be determined, and a foundation is laid for tracking users or services and the like based on the device identification.
