It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.

With continued reference to fig. 2, a flow 200 of one embodiment of a method of device ID determination in accordance with the present disclosure is shown. The method for determining the equipment ID comprises the following steps:

step 201, in response to that the determination function of the ID of the terminal device is turned on again after being turned off, if the terminal device installs the target application during the turn-off period of the determination function and the device ID of the target application jumps, determining the application with the highest priority among the applications installed in the terminal device, where the identifier with the priority as the application is selected as the priority of the primary identifier.

In this embodiment, an execution main body (for example, the terminal device shown in fig. 1) on which the method for determining the device ID operates may determine, if the function (that is, the shared path) for determining the ID of the terminal device is turned on again after being turned off, that is, if the terminal device can determine the ID again, and if the terminal device installs the target application during the turn-off period of the function is determined, and a device ID of the target application jumps, the execution main body may determine the application with the highest priority among the applications installed in the terminal device.

Each application installed by a device has its own priority. The priority here refers to the priority of the device identity being selected as the primary identity. The priority of different applications may be different. For example, the prioritization among xaapp, yapp, and Zapp may be: yapp > Xapp > Zapp, i.e., yapp is the highest priority followed by Xapp, and Zapp is the lowest priority.

The device ID (e.g., the CUID) of the target application may hop after the ID determination function of the terminal is turned off. After hopping, the device ID changes. Specifically, in the case where the device ID is the CUID, the CUID is composed of the DID and imei numbers. Among which DID may be the hopping.

In practice, the priority of different applications may be different, and only one application with the highest priority may be present on the terminal device. Alternatively, if there is a case where more than one application has the highest priority, an application with the highest priority may be determined from the applications with the highest priority according to a preset rule. For example, the preset rule may be to take the earliest installed application among the highest priority applications as a determined highest priority application, or to randomly take one application from among the highest priority applications as a determined highest priority application.

Step 202, determining the unique ID in the application of the application with the highest priority as the main identifier of the terminal device.

In this embodiment, the execution subject may determine, after determining the application with the highest priority, an intra-application unique ID (APP-CUID, AID) of the application with the highest priority as the main identifier MID of the terminal device.

The method provided by the above embodiment of the present disclosure may determine the primary identifier of the terminal device through the priority difference between the applications if the device ID of the target application is hopped when the ID determining function is turned off and the ID of the terminal device cannot be determined. Therefore, the method and the device can not only unify the identification of the terminal device, avoid different IDs corresponding to different data, provide convenience for data analysis of the terminal device, but also ensure the stability of the main identification after the ID of the device jumps through the priority, and avoid frequent change of the main identification to a certain extent.

In some optional implementations of any embodiment of the present disclosure, the step of re-determining the main identifier of the terminal device includes: in response to receiving ID report information reported by the terminal equipment, searching a main identifier of the terminal equipment in an ID database, wherein the ID report information comprises an in-application unique ID and an application list of an application installed in the terminal equipment; if the main identifier of the terminal equipment is found, determining the main identifier as the main identifier of the terminal equipment; and if the main identification of the terminal equipment is not found, determining the application with the highest priority in all the applications installed by the terminal equipment.

In these alternative implementations, the terminal devices in these implementations may be the same as the terminal device described above, or may be different terminal devices. After receiving the ID report information reported by the terminal device, the electronic device such as the server may search the ID database for the primary identifier of the terminal device. The ID database includes history data of the ID of the terminal device. The ID report information includes AIDs and application lists of applications installed in the terminal device, such as an application list add list.

Specifically, if the primary identifier of the terminal device is found in the ID database, the found primary identifier may be directly determined as the primary identifier of the terminal device. If the main identifier of the terminal device is not found, the executing agent may execute the main identifier determining step, and determine the in-application unique ID of the application with the highest priority as the main identifier MID of the terminal device.

These implementations can ensure the uniqueness of the MID by looking up in a database, avoiding repeated generation of MIDs.

Optionally, the determining, if the main identifier of the terminal device is found, the main identifier of the terminal device may include: and if the number of the searched main identifiers of the terminal equipment is at least two, generating the earliest main identifier from the searched main identifiers, and determining the earliest main identifier as the main identifier of the terminal equipment.

In these optional implementation manners, if at least two primary identifiers are found in the ID database, the electronic device may determine the primary identifier that is generated earliest, that is, the primary identifier that appears earliest, in the found primary identifiers as the primary identifier of the terminal device.

These optional implementations may use the earliest generated primary identifier as the primary identifier of the terminal device, thereby ensuring the stability of the primary identifier and avoiding frequent changes of the primary identifier.

In some optional implementations of any embodiment of the disclosure, the method may further comprise: acquiring a set of unique IDs in applications of each application installed by the terminal equipment; and determining the application-in-application unique ID of the application with the highest priority as the main identification MID of the terminal equipment, wherein the method comprises the following steps: and determining the unique ID in the application with the highest priority in the set as the main identification MID of the terminal equipment.

In these alternative implementations, the execution subject may obtain a set SID of intra-application unique IDs of respective applications installed by the terminal device. Specifically, the execution subject may obtain a set of transmissions of other electronic devices. Alternatively, the execution agent may generate a set of the IDs by using the intra-application unique IDs of the respective applications. Specifically, the execution agent may generate the set using a determination function of the ID.

After acquiring the set, the execution subject may determine a main identifier MID of the terminal device in the set.

The realization modes can improve the recall rate of the ID through the unique ID set in each application of the terminal equipment, and are beneficial to improving the accuracy of determining the main identification.

Further referring to fig. 3, the ID of the terminal device and the MID have a mapping relationship, and the generating step of the mapping relationship may include:

step 301, according to different browsers of the terminal device, collecting different IDs for the terminal device, where one browser corresponds to one ID to be collected, and different browsers correspond to different IDs.

In the present embodiment, the execution agent (e.g., the server shown in fig. 1) on which the device ID determination method is executed may collect different IDs for the terminal device according to different browsers of the terminal device. The execution body may collect different IDs for the terminal device in various ways according to different browsers of the terminal device. For example, a browser may have an ID to collect. The execution agent may collect one ID for each browser in a case where there is one ID for each browser. Or, there may be at least two IDs in one browser, and the execution agent may collect one of the at least two IDs by using a preset rule. For example, an ID with the highest frequency of use is selected from at least two IDs and determined as the ID to be collected. Furthermore, the execution agent may collect an ID other than the browser. The collected IDs may include, for example, the CUID, the anonymous device identifier OAID, the app package name pkg, the device number deviceid, the imei number. Specifically, the information may be collected from various logs (i.e., ID report information) uploaded by the terminal device, such as a CUID log (related to CUID, IDFA, and OAID, where IDFA is an advertisement Identifier, identifier for Advertising), an imei log (related to imei number and CUID), a terminal behavior log (related to CUID, UID, and IDFA, where UID is a user Identifier), and a call-up log (related to CUID).

Step 302, generating a mapping relation between different IDs and MIDs of the terminal devices.

In this embodiment, the execution main body may generate a mapping relationship between each of the different IDs and the MID of the terminal device.

The embodiment can generate mapping between different IDs and MIDs, thereby being beneficial to unifying various IDs of the terminal equipment to the MIDs and being beneficial to carrying out data analysis and statistics by utilizing the MIDs.

Optionally, the method may further include: in response to receiving a query request that has one of the mapping relationships involved as a query term, a query result is output that includes the other of the mapping relationships involved.

In these alternative implementations, the mapping relationship is a relationship of the two, the ID of the different IDs is the one to which the mapping relationship relates, and the MID is the other to which the mapping relationship relates. That is, if the query term includes any of the different IDs, the query result includes the MID. And if the query term includes the MID, the query result includes at least one of the different IDs.

In these implementations, the user may query the IDs of different data sources on the same user device using the mapping relationship.

Optionally, the MID has a function of mapping an ID mapped by the MID in the relationship, and the method further includes: and responding to the first ID mapped by the main identification for requesting to acquire the information flow, sending an information flow acquisition request comprising the main identification, and receiving the returned information flow.

Specifically, if the first ID mapped by the primary identifier is used for requesting to acquire an information stream, the first ID may also be carried in the information stream acquisition request. In a general case, the execution main body may send an information flow (e.g., feed flow) acquisition request for acquiring an information flow to a device such as a server, where the information flow acquisition request includes the first ID, and receive a feedback information flow. Accordingly, if the execution subject sends an information stream acquisition request including the MID to the device, the returned information stream is also received.

In these implementations, the MID may have the function of the mapped ID, so that various functions may be performed instead of the mapped ID, improving the ease of use of the terminal device identification.

Optionally, the collecting different IDs for the terminal device according to different browsers of the terminal device may include: and for each browser of the terminal equipment, responding to at least two IDs corresponding to the browser, and collecting the ID with the latest generation time in the at least two IDs.

Specifically, if the browser corresponds to at least two IDs, the ID whose generation time (i.e., appearance time) is the latest may be used as the ID to be collected. These alternative implementations may ensure timeliness of the collected IDs by the time-most recent IDs.

In some optional implementations of any embodiment of the disclosure, the method further comprises: responding to the closing of the ID determining function of the terminal equipment, if the terminal equipment is provided with a target application during the closing of the determining function and the equipment ID of the target application jumps, reporting first ID report information comprising identifier information of a main application and second ID report information comprising identifier information of the target application, wherein the main application is the application indicated by the main identification of the terminal equipment before the determining function is closed, the ID report information is used for executing a re-determining step, and the identifier information comprises the main identification; and in response to the fact that the ID determining function of the terminal equipment is restarted after the ID determining function is closed, reporting third ID report information comprising identifier information corresponding to each application installed in the terminal equipment.

In these alternative implementations, the identifier information of the primary application includes an intra-application unique ID of the primary application, a device ID of the terminal device before hopping, and a primary identifier assigned as the intra-application unique ID of the primary application. The identifier information of the target application may include an intra-application unique ID of the target application, a device ID of the terminal device after hopping, and another primary identity assigned as the intra-application unique ID of the target application. The identifier information is information of an identifier, that is, an ID, of an application of the terminal device.

After the ID determination function of the terminal device is recovered, identifier information corresponding to each application installed in the terminal device may be reported, and the identifier information constitutes third ID report information.

These optional implementation manners may help the server to execute a process of re-determining the primary identifier by determining and reporting identifier information of each application including the primary identifier when the ID determination function is turned back on after the shutdown.

Optionally, the primary identifier in the first ID report information is an intra-application unique ID of the primary application, the primary identifier of the second ID report information is an intra-application unique ID of the target application, and the primary identifier of the third ID report information is an intra-application unique ID of the primary application, where the priority of the primary application is higher than the priority of the target application.

As shown in fig. 4, it shows that (1) the ID determination function of the terminal device is turned on, the terminal device installs a hand X app first, and the reported ID report information includes that AID of the hand X is X, cuid.x of the hand X (i.e. DID in cuid.x) is a, and AID list (i.e. the aggregate SID of AID) is { X }.

(2) The terminal equipment is also provided with the good Y app, the reported ID report information comprises that AID of the good Y is Y, CUID.X of the good Y is a, AID list is { x, Y }, and mid is x. The priority of the hand X app is higher than the priority of the good Y app. Hand X app is the primary application.

(3) The ID determining function of the terminal equipment is closed for some reasons, the terminal is provided with the full Z app, the CUID.X jumps, and two pieces of ID report information, namely the first ID report information and the second ID report information, are respectively reported. The first ID report information includes that AID of hand X is X, cuid.x of hand X is a, AID list is { X, y }, and mid is X. The second ID report information includes that AID of full Z is Z, cuid.x of full Z is a', AID list is { Z }, mid is Z.

(4) After the determining function of the terminal device ID is resumed, the reported third ID report information includes that the AID of the hand X is X, the cuid.x of the hand X is a, and the AID list is { X, y, z }; good Y AID is Y, good Y cuid.x is a, AID list is { x, Y, z }; AID of full Z is Z, cuid.x of full Z is a', AID list is { x, y, Z }; mid is { x }.

The terminal device in these optional implementations may still use the in-application unique identifier of the master application with the highest priority as the master identifier after determining that the function is turned off and turned back on, thereby ensuring the uniqueness and stability of the master identifier.
