With the progress and development of scientific technology, more and more users use terminal devices (such as smart phones), so that many industries can collect user information according to device identifiers of the terminal devices, perform data analysis or service delivery according to the collected user information, and the like.

In general, a terminal device uses a device MAC (Media Access Control) address stored in an internal memory thereof as a device identifier, but the MAC address cannot be obtained in a global sharing manner in order to protect the privacy of a user.

While specific embodiments of the disclosure have been shown and described in detail in the drawings and foregoing description, such drawings and description are not intended to limit the scope of the disclosed concepts in any way, but rather to explain the concepts of the disclosure to those skilled in the art by reference to the particular embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

As described above, on the premise of protecting the privacy of the user, the terminal device combines one or more identification features of a company identification, an advertisement identification, an OpenUDID, and an OpenIDFA corresponding to the application program as the device identification.

In particular, the company identification is an identifier that the company sets for the application it develops. On the same terminal device, the company identifications corresponding to all the application programs of the same company are the same, and the company identifications corresponding to the application programs of different companies are different. In addition, after all applications of a company are uninstalled, reinstalling applications of the company will generate a new company identification.

Openudids were generated by the first application using the OpenUDID Software Development Kit (SDK). On the same terminal device, openudids corresponding to application programs of the same company are the same, and openudids corresponding to application programs of different companies are different. Further, similar to the company identification, if all applications using the OpenUDID software development kit are deleted (e.g., all uninstalls or system resets, etc.), a new OpenUDID will be generated when the applications using the OpenUDID software development kit are reinstalled.

The advertisement identification is an identifier set for an application having an advertisement service. On the same terminal device, the advertisement identifications corresponding to all the applications with the advertisement service are the same, however, not all the applications have the advertisement service, that is, the applications without the advertisement service do not have the advertisement identifications. Forcing an application to have an advertising service may affect the acquisition of the device identification.

OpenIDFA is specifically set for the disadvantages of advertisement identification, however its validity period is only one day. That is, if the application is not started and run on the same terminal device on the same day, the corresponding openidfas will be different.

As can be seen from the above, since the identification features corresponding to all applications in the terminal device are not completely consistent, the uniqueness of the device identifier formed by combining the identifiers cannot be satisfied, and thus, the collection of the user information according to the device identifier is not accurate enough.

Therefore, in order to enable all applications in the terminal device to acquire a unique device identifier, a device identifier acquisition method is particularly proposed.

Fig. 1 is an implementation environment related to the method for acquiring the device identifier. The implementation environment includes a terminal device 100 and a server 200.

FIG. 3 is a block diagram illustrating a server in accordance with an example embodiment. This hardware configuration is only one example to which the present disclosure may be applied, and is not to be considered as any limitation on the scope of use of the present disclosure, nor is it to be construed that the present disclosure needs to rely on the server 200.

The server 200 may have a large difference due to different configurations or performances, as shown in fig. 3, the server 200 includes: a power supply 210, an interface 230, at least one storage medium 250, and at least one Central Processing Unit (CPU) 270.

The application 253 is a computer program that performs at least one specific task on the operating system 251, and may include at least one module (not shown in fig. 3), each of which may respectively include a series of operating instructions for the server 200. Data 255 may be documents, pictures, etc. stored in disk.

The central processor 270 may include one or more processors and is configured to communicate with the storage medium 250 via a bus for computing and processing the mass data 255 in the storage medium 250.

As described above in detail, the server 200 to which the present disclosure is applied will be used to realize the acquisition of the device identifier in the terminal device 100, that is, the acquisition of the device identifier is performed by the central processor 270 reading a series of operation instructions stored in the storage medium 250.

Furthermore, the present disclosure can be implemented equally as hardware circuitry or hardware circuitry in combination with software instructions, and thus implementation of the present disclosure is not limited to any specific hardware circuitry, software, or combination of both.

Referring to fig. 4, in an exemplary embodiment, a method for acquiring a device identifier is applied to the server 200 in the implementation environment shown in fig. 1, and the method for acquiring a device identifier may be performed by the server 200 and may include the following steps:

and 310, receiving the identification characteristics of the application program reported by the terminal equipment.

In this embodiment, the identification feature includes at least one or more of a company identification, an advertisement identification, and a temporary device identification corresponding to the application program.

For example, the identification feature reported by the terminal device for the application program may include a company identifier, an advertisement identifier, and a temporary device identifier corresponding to the application program.

Or, the identification feature reported by the terminal device for the application program may include a company identification and a temporary device identification corresponding to the application program without the application program of the advertisement service.

It should be understood that the more content included in the identification feature reported by the terminal device for the application program, the more beneficial the application program obtains the device identification, however, according to different application scenarios, for example, in order to reduce an application scenario of data interaction between the server and the terminal device, the terminal device may also selectively report, for example, report only the temporary device identification.

As previously mentioned, a company identification is an identifier that the company sets for the application it develops. On the same terminal device, the company identifications corresponding to all the applications of the same company are the same, so the company identifications can be used for associating the applications of the same company.

For example, as shown in "idfv association" in fig. 4a, 100 applications of T corporation in the terminal device are associated together by the same corporation identification (idfv).

The advertisement identification is an identifier set for an application having an advertisement service. On the same terminal device, the advertisement identifications corresponding to all the application programs with the advertisement service are the same, so the advertisement identifications can be used for associating the application programs with the advertisement service.

For example, as shown in "idfa association" in fig. 4a, if one of 100 applications of company T has an advertisement service and 1 of 50 applications of company a has an advertisement service, the application of company T having the advertisement service and the application of company a having the advertisement service are associated with each other by the same advertisement identification (idfa).

The temporary device identifier is generated from device fingerprint information, which is information that is not frequently changed in the terminal device, but can be used to distinguish different terminal devices, including but not limited to device hardware information and device environment information. On the same terminal device, as long as the device fingerprint information is not changed, the temporary device identifiers corresponding to all the applications are the same, so that the temporary device identifiers can be used for associating all the applications in the terminal device, particularly for associating the applications without advertisement services.

For example, as shown in "TempID association" in FIG. 4a, if 1 of 50 applications of company A has an advertisement service, 49 have no advertisement service, but 50 applications have no corresponding temporary device identification (TempID), and 20 applications of company B have no advertisement service, but have corresponding temporary device identification, then the 50 applications of company A and the 20 applications of company B are associated together by the same temporary device identification (TempID).

In detail, the step of generating the temporary device identifier includes: collecting device fingerprint information, wherein the device fingerprint information comprises but is not limited to device hardware information, device starting time, operator information, system language, whether to break a prison or not, whether to open a mailbox or not, remaining disk space and the like; splicing the fingerprint information of the equipment according to a preset field rule; and calculating the fingerprint information of the spliced equipment according to an encryption algorithm (such as SHA1 algorithm), so as to obtain the temporary equipment identifier. The generation of the temporary device identifier may be performed when the terminal device is powered on, or may be performed when the application program is started and run.

After the temporary device identifier is generated, the terminal device stores the temporary device identifier in a local storage space for direct acquisition in subsequent use, which is beneficial to improving the processing efficiency of the terminal device.

As can be seen from the above, the correlation of all the application programs in the terminal device can be realized through the above identification features, as shown in fig. 4a, which is beneficial for different application programs that are subsequently correlated to each other to obtain a unique device identification.

Further, the identification features are collected by the terminal device when the application program starts running.

Specifically, when the application program starts to run, the terminal device obtains the company identifier corresponding to the application program by calling a preset system interface.

The terminal device also performs IDFA plug-in detection on the application program, if the IDFA plug-in is detected, the application program is indicated to have an advertisement service, and accordingly, the advertisement identification corresponding to the application program can be obtained. It should be noted that all the applications with the advertisement service will add the IDFA plug-in, so as to implement the publishing on the third-party application platform.

The temporary device identifier is obtained by the terminal device from the local storage space.

Certainly, in different application scenarios, for example, an application scenario with a high requirement on the real-time performance of the identification feature, the temporary device identification may be regenerated every time the application program starts to run, so as to effectively ensure the real-time performance of the temporary device identification.

Still further, the identification feature may further include one or more of OpenUDID, OpenIDFA, and historical device identification. The historical device identification is formed by locally storing the device identification after the terminal device receives the device identification returned by the server.

And reporting the collected identification characteristics to the server after the terminal equipment finishes collecting the identification characteristics.

Step 330, determining whether there is an identifier matching the identification feature in the association relationship according to the association relationship between the identifier stored by the server for the application program and the device identifier.

The association relationship at least comprises the identifier and the device identifier, and the server can know the device identifier associated with the identifier corresponding to the application program through the association relationship between the identifier stored for the application program in the server and the device identifier.

Specifically, the identifier corresponds to an identification feature, and also includes one or more of an advertisement identifier, a company identifier, and a temporary device identifier corresponding to the application program. Of course, in other embodiments, the identifier may further include one or more of OpenUDID, OpenIDFA, and historical device identifier.

Further, the association relationship may be represented by a look-up table or an array.

Taking the form of representing the association relationship by a lookup table as an example, as shown in fig. 4b, there is more than one association relationship stored for the application program in the server, and the association relationships corresponding to different application programs may be different. Wherein, the ID represents the application identification of the application program, the IDFA, the IDFV and the TempID respectively represent the advertisement identification, the company identification and the temporary device identification in the identifier, and the MID represents the device identification. And the "/" indicates that the terminal device does not report the advertisement identification, that is, the corresponding application program has no advertisement service.

It is understood that, in order to issue the device identifier for the application program, the server at least needs to know whether the identification feature of the application program matches with the identifier in the association relationship through the association relationship.

If yes, step 350 is performed, and the associated device identifier is obtained from the association relationship directly according to the identifier matched with the identification feature.

Otherwise, if the match is not found, go to step 370.

Specifically, the identification features or identifiers each include one or more of an advertisement identifier, a company identifier, and a temporary device identifier corresponding to the application program, and accordingly, the matching includes matching of the advertisement identifier, matching of the company identifier, and matching of the temporary device identifier.

The matching of the advertisement identifications means that the advertisement identifications in the identifiers are consistent with the advertisement identifications in the identification features, the matching of the company identifications means that the company identifications in the identifiers are consistent with the company identifications in the identification features, and the matching of the temporary device identifications means that the temporary device identifications in the identifiers are consistent with the temporary device identifications in the identification features.

Through the matching of the identification features and the identifiers in the association relationship, all the application programs in the terminal equipment can be associated with each other through at least one or more identification features of the corresponding company identification, advertisement identification and temporary equipment identification, namely the application programs which are associated with each other belong to the same terminal equipment.

And step 350, obtaining the associated equipment identification according to the identifier matched with the identification characteristic in the association relation.

For example, as shown in fig. 4b, the identification features reported by the terminal device for the application program with the application ID of ID2 include an advertisement ID a1, a company ID V2, and a temporary device ID — 1. The server matches the identification characteristics according to the identifiers in the association relationship, and the advertisement identification A1 in the identification characteristics is obtained to be consistent with the advertisement identification A1 corresponding to the application program with the application identification ID1, so that the matching of the advertisement identifications is met.

When the identification characteristics are matched with the identifiers in the association relationship, the application program with the application identification of 2 and the application program with the application identification of 1 are associated with each other, and both of the application programs belong to the same terminal equipment, namely, the application program with the application identification of ID2 and the application program with the application identification of ID1 have the same equipment identification. Thus, the device identification MID _1 is obtained by associating the advertisement identification a1 corresponding to the application program with the application identification ID1, and the device identification MID _1 is used as the device identification of the application program with the application identification ID 2.

Step 370, calculating the identification features according to a preset algorithm to generate the device identification.

When the identification feature is not matched with the identifier in the association relationship, that is, the application program corresponding to the identification feature cannot be associated with the application program corresponding to the identifier in the association relationship, that is, the device identification cannot be obtained by associating the identifier matched with the identification feature.

At this time, the server determines that the application program corresponding to the identification feature belongs to the new terminal device, and generates a new device identification for the application program corresponding to the identification feature.

Preferably, the generation is performed by calculating the identification features according to a preset algorithm.

For example, an encryption algorithm is used as a preset algorithm, the advertisement identifier, the company identifier and the temporary device identifier in the identifier feature are encrypted and calculated respectively to obtain corresponding encryption results, and then all the encryption results are spliced to form the device identifier. The splicing mode may be mutual accumulation, or splicing through underlining.

Step 390, the device identifier is issued to the terminal device.

After the generated device identifier or the associated device identifier is obtained, the server issues the device identifier to the terminal device, so that the terminal device receives the device identifier.

Further, after receiving the device identifier returned by the server for the application program, the terminal device may store the device identifier in the local storage space according to the application identifier of the application program, so as to form a historical device identifier corresponding to the application program, thereby facilitating subsequent correction of the device identifier obtained by the application program.

For example, when the terminal device receives the device identifier issued by the server for the application program again, the issued device identifier is compared with the historical device identifier corresponding to the application program, and if the issued device identifier is not consistent with the historical device identifier corresponding to the application program, the historical device identifier is updated by the issued device identifier, so that the uniqueness of the device identifiers acquired by all the application programs in the terminal device is ensured, and meanwhile, the consistency of the device identifiers of the terminal side and the server side is also ensured.

Through the process, all the application programs in the terminal equipment can acquire the unique equipment identification, and the terminal equipment can collect more accurate user information according to the equipment identification.

For example, in a specific application scenario, the push server needs to push advertisement services for a user, and before that, the push server needs to know relevant information of the user, for example, the relevant information includes, but is not limited to, a location, an age, a sex, an occupation, hobbies, and the like.

Based on this, the terminal device where the user is located will perform the collection of user information. It should be appreciated that the more user information is collected, the more beneficial the push server is for accurate push of advertising services. Specifically, the terminal device collects user information through application identifiers of a plurality of application programs, and reports the collected user information to the push server according to the device identifiers.

The device identifiers acquired by the application programs are unique, so that after the push server receives the user information reported by the device identifiers, the push server knows that the user information is reported by the same terminal device, namely belongs to the same user, and further accurately knows the related information of the user through statistical analysis of the user information, so that accurate advertisement service push is realized.

Referring to fig. 5, in an exemplary embodiment, the method as described above may further include the steps of:

and step 410, judging whether the association relationship corresponding to the application program exists in the server according to the application identifier of the application program.

Since the server receives the identifier characteristics reported by the terminal device for the application program, and also acquires the device identifier, the association relationship in the server may change, for example, the identifier in the association relationship changes due to the reported identifier characteristics, or the device identifier in the association relationship changes due to the acquired device identifier.

Therefore, the server needs to determine whether a new association relationship needs to be stored for the application program, so that other subsequent application programs can be associated with the application program through the identifier in the new association relationship.

It should be understood that if the association relationship corresponding to the application program already exists in the server, it is not necessary to store a new association relationship for the application program again, which is beneficial to improving the utilization rate of the storage space in the server.

Based on this, in this embodiment, the determination is implemented by the application identifier of the application program, that is, it is determined whether the association relationship corresponding to the application program exists in the server according to the application identifier of the application program.

If it is determined that the association relationship corresponding to the application program already exists in the server, the process proceeds to step 430.

Otherwise, if it is determined that the association relationship corresponding to the application does not exist in the server, step 450 is performed.

And 430, performing repair processing according to the association relationship corresponding to the application program by the identification characteristics and the equipment identification.

The repair processing includes update processing and deletion processing.

Taking the update process as an example, the identification features reported by the terminal device for the application program with the application identifier ID6 include an advertisement identifier a5, a company identifier V5, and a temporary device identifier Oid _ 3. The server matches the identification features according to the identifiers in the association relationship, and obtains that the temporary device identification Oid _3 in the identification features is consistent with the temporary device identification Oid _3 corresponding to the application program with the application identification ID5, so that the matching of the temporary device identifications is met.

When the identification features are matched with the identifiers in the association relationship, the device identification MID _3 is obtained according to the association of the temporary device identification Oid _3 corresponding to the application program with the application identification ID5, and the device identification MID _3 is used as the device identification of the application program with the application identification ID 6.

At this time, since the association relationship corresponding to the application program with the application identifier ID6 already exists in the server (see "before repair" in fig. 4 b), the association relationship corresponding to the application program is updated according to the acquired device identifier MID _3 and the reported temporary device identifier Oid _3, that is, the device identifier MID _4 in the association relationship is updated by the device identifier MID _3, the temporary device identifier Oid _6 in the association relationship is updated by the temporary device identifier Oid _3, and the association relationship corresponding to the application program after the update processing is referred to "after repair" in fig. 4 b.

That is, the application and the application with the application identifier ID5 originally belong to the same terminal device, but since the identification characteristics (a5\ V5\ Oid _6) reported by the terminal device for the application are not matched with the identifiers in any association relationship, the server mistakenly considers that the application belongs to a new terminal device, and a new device identifier MID _4 is generated for the application.

When the application program starts to run again, due to the recalculation of the temporary device identifier, the terminal device realizes the matching of the identifier in the identifier characteristic (A5\ V5\ Oid _3) reported for the application program again through the temporary device identifier Oid _3, so that the application program can be associated with the application program with the application identifier ID5, and the application program with the application identifier ID5 can acquire the same device identifier MID _ 3.

Therefore, the server completes the repair of the association relation corresponding to the application program through the updating process, so that all the application programs in the same terminal device can acquire the unique device identification.

It is worth mentioning that the repair process can be accomplished not only by the temporary device identifier, but also by the advertisement identifier or the company identifier. For example, an application program is upgraded by a version, and upgraded from a version without an advertisement service to a version with an advertisement service, and accordingly, the terminal device adds an advertisement identifier to the identifier feature reported by the application program, so that the application program can be associated with other application programs by the added advertisement identifier, and further, the server can repair the association relationship corresponding to the application program.

Further, if the identifier and the device identifier in the updated association completely match the identifiers and the device identifiers in other associations in the server, even if the applications corresponding to the associations are different, the server deletes the duplicate associations, for example, according to the timestamp information during storage, thereby reducing the occupancy rate of the storage space in the server and further improving the utilization rate of the storage space in the server.

Further, as shown in fig. 5, in an exemplary embodiment, the method as described above may further include the steps of:

step 450, when it is determined that the association relationship corresponding to the application does not exist in the server, further determining whether the identifier feature is completely consistent with the identifier matched with the identifier feature.

As described above, the server performs deletion processing on the duplicate association relationship, which means that the identifiers and the device identifiers in at least two association relationships are completely consistent.

Based on this, before storing a new association relationship for the application program, the server further determines whether the identification features are completely consistent with the identifiers matched with the identification features, so that occurrence of repeated association relationships is avoided, and processing efficiency of the server is reduced.

If the identification characteristics are not completely consistent with the matched identifiers, i.e. there is at least one inconsistency, e.g. the advertisement identification is inconsistent, and/or the company identification is inconsistent, and/or the temporary device identification is inconsistent, step 470 is entered, and a new association relationship is stored for the application program, so as to form an association relationship corresponding to the application program.

Otherwise, if the identification characteristics are judged to be completely consistent with the matched identifiers, the server does not store a new association relation for the application program.

Step 470, establishing an association relationship between the identifier feature and the device identifier according to the application identifier of the application program, and storing the association relationship.

When the identification characteristics are judged to be not completely consistent with the matched identifiers, a new association relationship needs to be stored for the application program, so that other subsequent application programs can be associated with the application program through the new association relationship to obtain the same device identification.

Specifically, the identifier characteristics reported by the terminal device for the application program are used as the identifier corresponding to the application program, and according to the identifier and the device identifier obtained before, the association relationship between the identifier and the device identifier is established and stored in the server, so that a new association relationship stored by the server for the application program is formed.

Through the process, all the application programs in the terminal equipment can be associated with each other through at least one or more identification characteristics of the corresponding company identification, the advertisement identification and the temporary equipment identification, so that the association efficiency of the equipment identification in the server is improved.

For example, as shown in fig. 4b, the identification features reported by the terminal device for the application program with the application ID of ID7 include an advertisement ID a6, a company ID V6, and a temporary device ID — 4. Since the identification feature cannot be matched with the identifier in any association relationship in the server, the server generates a device identifier Oid _5 for the application program, and accordingly, the server also establishes an association relationship between the identifier and the device identifier for the application program so as to form an association relationship corresponding to the application program by storing the association relationship.

Assuming that there is a subsequent application program with application ID9, and the identification features reported by the terminal device for the application program at least include company identification V6, the server can match the identification features according to each identifier in the association relationship, obtain that the company identification V6 in the identification features is consistent with the company identification V6 corresponding to the application program with application identification ID7, satisfy the matching of the company identifications, further obtain device identification MID _5 according to the company identification V6 corresponding to the application program with application identification ID7, and use the device identification MID _5 as the device identification of the application program with application identification ID 9.

Referring to fig. 6, in an exemplary embodiment, step 470 may include the following steps:

step 471, determining the corresponding timestamp information when the identification features are reported.

Step 473, the device identifier is calculated by taking the random number, the timestamp information and the identifier characteristics as input parameters of a preset algorithm.

In this embodiment, the preset algorithm is an encryption algorithm, a randomly generated random number, timestamp information reflecting the reporting time of the identification feature, and the identification feature are used as input parameters of the encryption algorithm, and an output device identifier is calculated.

The identification features include, but are not limited to, advertisement identification, company identification, temporary device identification, historical device identification, and the like corresponding to the application program.

In an exemplary embodiment, the identification feature further comprises a historical device identification corresponding to the application stored on the terminal device.

After the generated device identifier or the associated device identifier is obtained, the server may issue the device identifier to the terminal device. It should be understood that, if the historical device identifier stored for the application program in the terminal device is consistent with the device identifier, the server does not need to repeatedly issue the application program, so that interaction with the terminal device can be reduced, and the processing efficiency of the server is improved.

Based on this, prior to step 390, the method as described above may further include the steps of:

and comparing whether the equipment identification is consistent with the historical equipment identification.

If the two are not consistent, step 390 is entered, and the device identifier is issued to the terminal device. Otherwise, if the two are consistent, the server does not send the device identifier to the terminal device.

Further, the server interacts with the terminal device in the form of a return message.

Specifically, if the device identifier is not consistent with the historical device identifier, the return message carries the device identifier, and the return message is sent to the terminal device. If the equipment identification is consistent with the historical equipment identification, the return message carries the comparison result, and the return message is sent to the terminal equipment. Through the setting of the return message, the terminal equipment can obtain the response of the server in time, and unnecessary waiting of the terminal equipment is avoided, so that the processing efficiency of the terminal equipment is improved.
