Description

A method for generating an advertisement tracking identifier and related equipment

Technical Field

The present invention relates to the field of information processing technology, and in particular to a method for generating an advertisement tracking identifier and related equipment.

Background Art

Online advertising refers to advertisements posted or published on the Internet using advertising banners, text links, multimedia, etc. As Internet technology becomes more and more sophisticated and more and more Internet users are using it, online advertising has developed rapidly, and the advertising push business has also developed accordingly.

Ad push service refers to the service of delivering some personalized advertisements related to the visit in a targeted manner when the user uses the browser or application software. The principle is that the advertising service provider obtains the user's user behavior data, analyzes these user behaviors, and uses the advertising tracking ID to identify the user, and then pushes personalized advertisements to different users. However, currently, advertising service providers use the International Mobile Equipment Identity (IMEI) as an advertising tracking identifier, and the IMEI cannot be turned off or reset by the user. Once the advertising service provider obtains the user's IMEI, it can not only obtain the user's behavior information but also some of the user's personal privacy information, which poses a high risk in protecting the user's personal information and privacy.

Therefore, how to generate advertising tracking identifiers without relying on user sensitive information is an urgent problem to be solved.

Summary of the invention

The technical problem to be solved by the embodiments of the present invention is to provide a method and a related device for generating an advertisement tracking identifier, which can realize the generation of the advertisement tracking identifier without relying on user sensitive information and avoid the problem of user privacy leakage.

In a first aspect, an implementation case of the present invention provides a method for generating an advertising tracking identifier, characterized in that it is applied to a server, comprising: receiving M advertising tracking identifier requests sent by M clients, wherein each of the M advertising tracking identifier requests includes first device information of the corresponding client; the first device information includes a first application installation list, and the first application installation list includes application package names, application names and installation times of N applications installed on the corresponding client; the M is greater than or equal to 1; the N is greater than or equal to 1; generating M first advertising tracking identifiers based on the M first device information included in the M advertising tracking identifier requests; each first advertising tracking identifier of the M first advertising tracking identifiers is used to identify the client under the corresponding first device information; and returning each first advertising tracking identifier to the corresponding client respectively.

In the prior art, when the server describes a user portrait for the client (for example, the user portrait may be a young lady with purchasing power, etc.), it is necessary to use the ad tracking ID provided by the client to associate the user portrait and identify the client through the ad tracking ID, so that the server can then deliver personalized ads to the client based on the user portrait. However, the ad tracking ID is generated by the client based on some user sensitive information (such as user device identification information, etc.). When the server uses the ad tracking ID, it may be associated with the user sensitive information of the corresponding client, which may cause the risk of leaking user privacy. In addition, client terminals using different operating systems use different identification generation rules when generating ad tracking IDs. Therefore, different client terminals may generate the same ad tracking ID according to their respective identification generation rules, which in turn causes the server to be unable to accurately distinguish different clients using the ad tracking ID provided by the client.

Different from the above-mentioned prior art in which the client generates the ad tracking ID, in the embodiment of the present invention, the server uniformly generates the ad tracking IDs of various clients, and the server avoids the problem of user privacy leakage caused by using the ad tracking ID generated by the client according to the user sensitive information, and also avoids the problem of being unable to uniformly manage the ad tracking IDs of different types of clients due to different rules for generating ad tracking IDs by different types of clients. Instead, the server uniformly generates an ad tracking identifier with a unified rule for each client according to some non-user sensitive information provided by different clients, and then uses the ad tracking identifier to identify the corresponding client, so that the ad tracking identifier that can accurately distinguish different clients can be generated without relying on user sensitive information and the client operating system. Specifically, after receiving the ad tracking identifier request sent by M clients, the server responds to the M ad tracking identifier requests and uses the same identifier generation rule to process the non-user sensitive information in each ad tracking identifier request to generate a corresponding ad tracking identifier, and the non-user sensitive information includes the application package name, application name and installation time of multiple applications installed by the user on the client device. Next, the server sends a corresponding session response to the M clients, and the session response includes the ad tracking identifier of the corresponding client. Through the embodiments of the present invention, the server does not rely on user privacy information and the client operating system to generate an advertising tracking identifier, and then the server can use the advertising tracking identifier generated by itself to identify multiple clients, thereby protecting user privacy while enabling the server to more accurately distinguish different clients.

In a possible implementation, the first device information also includes the device model, version, language country, operating system, and operating system version of the corresponding client; the first device information is obtained by the corresponding client from an advertising software development kit, and the advertising software development kit is a software development kit provided by the server to the corresponding client.

In an embodiment of the present invention, since the advertising SDK provided by the server is installed in the client side, the client can obtain some non-user sensitive information of the client device through this advertising SDK, and carry this non-user sensitive information when the client sends an advertising tracking identifier request to the server, so that the server can subsequently generate a corresponding advertising tracking identifier based on this non-user sensitive information. This non-user sensitive information includes the application package names, application names, and installation time of multiple applications installed on the client device, and may also include the device model, version, language country, operating system, and operating system version of the client device. It should be noted that for the installed applications in the application list, when they are not associated with an individual user, they are non-user sensitive information and do not involve user privacy. The more information that does not involve user privacy is included in the request, the less likely it is that duplication will occur when the advertising tracking identifier is generated by the server, and the advertising tracking identifier generated by the server can more accurately distinguish different clients.

In a possible implementation manner, the method further includes: storing a mapping relationship between each first advertisement tracking identifier and the corresponding first device information in an identifier database.

In the embodiment of the present invention, after the server responds to the M advertising tracking identifier requests, M advertising tracking identifiers are generated. The server stores the mapping relationship between the M advertising tracking identifiers and the corresponding non-user sensitive information in the identification database, so that the server can subsequently characterize user portraits according to the mapping relationship between these advertising tracking identifiers and the corresponding non-user sensitive information. At the same time, after the server generates the advertising tracking identifier, the advertising tracking identifier can be compared with the advertising tracking identifiers already existing in the identification database to determine whether the same advertising tracking identifier is generated, thereby avoiding the situation where multiple clients correspond to the same advertising tracking identifier, and realizing the protection of user privacy while the server can more accurately distinguish different clients.

In a possible implementation, the method also includes: receiving L update advertising tracking identifier requests from L clients among the M clients, wherein each of the L update advertising tracking identifier requests includes second device information of the corresponding client; the second device information includes a second application installation list, and the second application installation list includes application package names, application names and installation times of S applications installed on the corresponding client; the L is greater than or equal to 1; the S is greater than or equal to 1; generating L second advertising tracking identifiers based on the L second device information included in the L update advertising tracking identifier requests; each second advertising tracking identifier of the L second advertising tracking identifiers is used to identify the client under the corresponding second device information.

In an embodiment of the present invention, after receiving an update advertisement tracking identifier request sent by L clients among M clients, the server responds to the L update advertisement tracking identifier requests and uses the same identifier generation rule to process the current non-user sensitive information in each update advertisement tracking identifier request to generate a new advertisement tracking identifier, wherein the current non-user sensitive information includes the application package name, application name and installation time of multiple applications currently installed on the corresponding client device. In the prior art, if an illegal element obtains an advertisement tracking identifier, it can always use the advertisement tracking identifier to search for the corresponding client, which will cause user privacy leakage. However, through an embodiment of the present invention, when the current non-user sensitive information of the client changes, the client can send an update advertisement tracking identifier request to the server, and the server generates a new advertisement tracking identifier for the client in response to the request, thereby dynamically updating the advertisement tracking identifier of the client. Even if the illegal element obtains the advertisement tracking identifier of the client, the identifier will also change, so the illegal element cannot always search for the same client through an advertisement tracking identifier.

In a possible implementation, the second device information also includes the device model, version, language country, operating system, and operating system version of the corresponding client; the second device information is obtained by the corresponding client from the advertising software development kit.

In an embodiment of the present invention, since the advertising SDK provided by the server is installed in the client side, the client can obtain some non-user sensitive information of the current client device through this advertising SDK, and carry this current non-user sensitive information when the client sends an advertising tracking identifier request to the server side, so that the server side can subsequently generate a corresponding advertising tracking identifier based on this current non-user sensitive information. This current non-user sensitive information includes the application package names, application names, and installation times of multiple applications currently installed on the client device, and may also include the device model, version, language country, operating system, and operating system version of the client device. The more information that does not involve user privacy included in the request, the less likely it is that duplication will occur when the advertising tracking identifier is generated by the server side, and the advertising tracking identifier generated by the server side can more accurately distinguish different clients.

In a possible implementation, the method further includes: determining whether there is an identifier identical to the L second advertisement tracking identifiers in the identifier database; if there is no identifier identical to the L second advertisement tracking identifiers in the identifier database, returning each second advertisement tracking identifier to the corresponding client.

In the embodiment of the present invention, when the server generates L new advertising tracking identifiers in response to the advertising tracking identifier update requests of L clients, the L new advertising tracking identifiers are compared with the advertising tracking identifiers stored in the identification database, and if no identical advertising tracking identifiers appear, each new advertising tracking identifier is returned to the corresponding client. By comparing the newly generated advertising tracking identifier with the advertising tracking identifier previously stored in the identification database, the situation where the same advertising tracking identifier corresponds to multiple clients in abnormal circumstances is avoided, thereby achieving dynamic updating of the advertising tracking identifier of the client and enabling the server to accurately distinguish different clients in abnormal circumstances.

In a possible implementation, each of the L advertising tracking identifier update requests also includes the first advertising tracking identifier of the corresponding client; the method also includes: storing a mapping relationship between each second advertising tracking identifier and the corresponding second device information in the identifier database, and associating the second advertising tracking identifier corresponding to the same client with the first tracking identifier.

In an embodiment of the present invention, if L clients that need to update the advertising tracking identifier send advertising tracking identifier update requests to the server respectively, and the advertising tracking identifier update request carries the current advertising tracking identifier of the corresponding client (such as the first advertising tracking identifier), then after the server responds to the advertising tracking update request, it stores the mapping relationship between each new advertising tracking identifier and the corresponding current non-user sensitive information in the identification database, and associates the current advertising tracking identifier of the same client with the new advertising tracking identifier. If the server subsequently finds that the new advertising tracking identifier is associated with other advertising tracking identifiers when portraying the user portrait based on the mapping relationship between the new advertising tracking identifier and the corresponding current non-user sensitive information, the user portrait features corresponding to the associated advertising tracking identifier are added to the new user portrait, so that the server can deliver personalized advertisements more accurately.

In a possible implementation manner, the method further includes: sending a mapping relationship between each first advertisement tracking identifier and the corresponding first device information stored in the identifier database to a third-party platform.

In an embodiment of the present invention, the server may send the mapping relationship between the advertising tracking identifier and the corresponding non-user sensitive information stored in the identification database to other third-party platforms. The other third-party platforms may perform user profiling based on these mapping relationships in combination with platform requirements, and the other third-party platforms may find the corresponding client based on the advertising tracking identifier in these mapping relationships.

In a possible implementation manner, the method further includes: sending a mapping relationship between each second advertisement tracking identifier and corresponding second device information stored in the identifier database to a third-party platform.

In an embodiment of the present invention, when the advertising tracking identifier of a client changes, the server may send the mapping relationship between the new advertising tracking identifier and the corresponding current non-user sensitive information stored in the identifier database to other third-party platforms, and other third-party platforms may perform user profiling based on these mapping relationships in combination with platform requirements, and other third-party platforms may find the corresponding client based on the new advertising tracking identifier in these mapping relationships.

In a second aspect, the present application provides a method for generating an advertising tracking identifier, characterized in that it is applied to a client, including: reading first device information from an advertising software development kit; the first device information includes a first application installation list; the first application installation list includes application package names, application names and installation times of N applications installed on the client; the advertising software development kit is a software development kit provided to the client by a server; the N is greater than or equal to 1; sending an advertising tracking identifier request to the server, the advertising tracking identifier request including the first device information; after the server responds to the advertising tracking identifier request, receiving the first advertising tracking identifier returned by the server, and storing the mapping relationship between the first advertising tracking identifier and the first device information in a local database; the first advertising tracking identifier is generated by the server according to the first device information and is used to identify the client under the first device information.

In an embodiment of the present invention, since the advertising SDK provided by the server is installed in the client, the client can obtain some non-user sensitive information of the current device through this advertising SDK, and carry these current non-user sensitive information when the client sends an advertising tracking identifier request to the server, so that the server can subsequently generate corresponding advertising tracking identifiers based on these current non-user sensitive information. These current non-user sensitive information include the application package names, application names and installation times of multiple applications currently installed on the client device. The more information that does not involve user privacy included in the request, the less likely it is that duplication will occur when the advertising tracking identifier is generated by the server, and the advertising tracking identifier generated by the server can more accurately distinguish different clients. After the server responds to the advertising tracking identifier request, the client receives the advertising tracking identifier sent by the server, so that the server can find the client corresponding to the advertising tracking identifier.

In a possible implementation, the method further includes: in response to a request to start the client, starting the client and reading a current application installation list on the client; the current application installation list includes application package names, application names, and installation times of S applications currently installed by the client; the S is greater than or equal to 1; determining whether the application package names, application names, and installation times of the N applications in the first application installation list are the same as the application package names, application names, and installation times of the S applications in the current application installation list; if not, the current application installation list is a second application installation list, and a request to update an advertisement tracking identifier is sent to the server; the request to update an advertisement tracking identifier includes second device information; the second device information includes the second application installation list.

In an embodiment of the present invention, when the client is started again, the client will read the current non-user sensitive information through the advertising SDK, and then compare the current non-user sensitive information with the non-user sensitive information previously stored in the local database. If the two pieces of information change, a request to update the advertising tracking identifier is sent to the server to update the advertising tracking identifier of the current client.

In a possible implementation, the second device information also includes the device model, version, language country, operating system, and operating system version of the client; the update advertising tracking identifier request also includes the first advertising tracking identifier; and the second device information is obtained from the advertising software development kit.

In an embodiment of the present invention, since the advertising SDK provided by the server is installed in the client side, the client can obtain some non-user sensitive information on the client device through this advertising SDK, and carry this non-user sensitive information when the client sends an advertising tracking identifier request to the server, so that the server can generate a corresponding advertising tracking identifier based on this non-user sensitive information. This non-user sensitive information includes the application package names, application names, and installation times of multiple applications installed by the user on the client, and may also include the client's device model, version, language country, operating system, and operating system version. The more information that does not involve user privacy included in the request, the less likely it is that duplication will occur when the advertising tracking identifier is generated by the server, and the advertising tracking identifier generated by the server can more accurately distinguish different clients.

In a possible implementation, the method further includes: receiving a second advertising tracking identifier returned by the server after the server responds to the request to update the advertising tracking identifier; deleting the mapping relationship between the first advertising tracking identifier and the first device information stored in the local database, and storing the mapping relationship between the second advertising tracking identifier and the second device information in the local database; the second advertising tracking identifier is generated by the server according to the second device information and is used to identify the client under the second device information.

In an embodiment of the present invention, when the server generates a new advertising tracking identifier in response to a request to update the advertising tracking identifier and returns the new advertising tracking identifier to the client, after receiving the new advertising tracking identifier, the client stores the mapping relationship between the new advertising tracking identifier and the corresponding current non-user sensitive information in a local database, and then deletes the mapping relationship between the advertising tracking identifier and the corresponding non-user sensitive information previously stored in the local database, thereby enabling the client to dynamically update the advertising tracking identifier.

DETAILED DESCRIPTION

The embodiments of the present invention will be described below in conjunction with the accompanying drawings in the embodiments of the present invention.

The terms "first", "second", "third" and "fourth" etc. in the specification and claims of the present application and the drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

Below, some terms in this application are explained to facilitate understanding by those skilled in the art.

(1) The Application Anonymous Device Identifier (AAID) can be generated when the application is installed. It is anonymous and has no privacy risk. The AAID can be reset when the device is restored to factory settings, the application is uninstalled, the application data is cleared, or the device manufacturer resets it. The AAID is only associated with a single application, which facilitates user statistics, etc.

(2) Google Advertising Identifier (GAID): In the Google ecosystem, Google uses GAID for ad tracking. GAID is assigned by Google Mobile Service (GMS), but it cannot be used on mobile phones without GMS system.

(3) Identifier for Advertising (IDFA): An advertising identifier provided by Apple for tracking users. Apple’s iOS system basically uses IDFA for advertising tracking, and users can turn off or reset the ID in settings.

(4) Identifier for Vendor (IDFV) is an advertising identifier provided by Apple for tracking users, but different application information is shared. IDFV is provided to developers for use, specifically for the same developer to analyze user behavior and make personalized recommendations for their own apps. It is only available between apps developed by the developer, and external apps and advertisements cannot read this ID.

(5) International Mobile Equipment Identity (IMEI) is the abbreviation of International Mobile Equipment Identity. It is a 15-digit "electronic serial number" that corresponds to each mobile phone. Each IMEI is unique in the world.

(6) The Mobile Security Alliance (MSA) was jointly initiated by the China Academy of Information and Communications Technology (CAICT) and other important institutions in various links of the industry chain, including terminal manufacturers, security companies, universities, research institutions, Internet companies, chip companies, and solution companies.

(7) Open Anonymous Device Identifier (OAID) is similar to IDFA in iOS. It is an ID used specifically for precision advertising tracking of users. Users can turn it off or reset it. OAID is only used in the Android system and is not applicable to Google's ecosystem, which uses GAID.

(8) Unique Device Identifier (UDID) is an ID used internally by mobile phone manufacturers and is not open to the public. UDID is a string generated for the current device, which is guaranteed to be unique and unchanged compared to other devices. It can be used to count the number of visits to the product or the statistics of user operations.

(9) The Vender Anonymous Device Identifier (VAID) is somewhat similar to IDFV in iOS. It is used by developers to analyze user behavior and provide personalized recommendations in applications developed by the same developer. It can only be used between applications developed by the developer. External applications and advertisements cannot read this ID.

First, the technical problems to be solved by this application are analyzed and proposed. In the prior art, the technologies for generating advertising tracking identifiers include the following solutions: Solution 1, Solution 2, Solution 3, and Solution 4:

Solution 1: Use IMEI (International Mobile Equipment Identity) as an ad tracking identifier.

Disadvantages: IMEI cannot be turned off or reset by users. If other platforms obtain the user's IMEI, they can associate it with privacy information based on the user's IMEI, which poses a high risk of non-compliance in terms of personal information privacy protection. Therefore, user consent must be obtained when collecting information, and encryption is also required when storing data.

Solution 2: Use OAID as the ad tracking identifier.

Disadvantages: Only Android devices can use OAID as an ad tracking identifier. Devices of other systems do not have OAID, and the server cannot uniformly manage the ad tracking identifiers of different clients.

Solution 3: Use GAID as the ad tracking identifier.

Disadvantages: Only devices in the Google ecosystem can use GAID as an ad tracking identifier. Devices of other systems do not have GAID, and the server cannot uniformly manage the ad tracking identifiers of different clients.

Option 4: Use IDFA as an ad tracking identifier.

Disadvantages: Only devices in the iOS ecosystem can use IDFA as an ad tracking identifier. Devices of other systems do not have IDFA, and the server cannot uniformly manage the ad tracking identifiers of different clients.

In summary, in the existing technology for generating ad tracking identifiers, the generation of ad tracking identifiers will rely on user sensitive information, resulting in the problem of user privacy leakage. At the same time, the generation of ad tracking identifiers in the existing technology also depends on the operating system of the device, resulting in the problem that the server cannot uniformly manage the ad tracking identifiers of different clients. Therefore, the method for generating ad tracking identifiers provided in this application is used to solve the above technical problems.

To facilitate understanding of the embodiments of the present invention, the following exemplary scenarios are listed for application of a method for generating advertisement tracking in the present application. The following two scenarios may be included:

Scenario 1: The advertising service platform pushes advertisements to the target user. In this scenario, the advertising service platform is the server in the embodiment of the present invention, and the target user's application software is the client. With the popularization of the Internet, Internet advertising has become an important part of the modern marketing media strategy, so how to place advertisements while maximizing revenue has become the focus of the advertising service platform. If the advertising platform can obtain non-user sensitive information on the target user's device, and then perform user behavior analysis to portray the user's behavior portrait, it can more accurately place personalized advertisements to the target user, thereby maximizing advertising revenue compared to general advertising delivery strategies. For example, after the advertising service platform obtains information that the target user has not installed the Taobao application, it will push advertisements for installing the Taobao application to the target user in a targeted manner. In the process of the advertising service platform obtaining the target user's behavior information and placing personalized advertisements, the advertising tracking identifier generated by the method provided in this application can allow the advertising service platform to better locate the target user while protecting the user's privacy, so that the advertising service platform can place advertisements more accurately.

Scenario 2: Scenario of docking between the advertising service platform and the third-party platform. In this scenario, the advertising service platform is the server end in the embodiment of the present invention, and the third-party platform is other advertising service platforms. With the popularization of the Internet, Internet advertising has become an important part of the modern marketing media strategy, so how to place advertisements while maximizing revenue has become the focus of attention of various advertising service platforms. If an advertising service platform generates an advertising tracking identifier according to the method provided in this application, and then the advertising service platform shares the advertising tracking identifier with other advertising service platforms, it can be achieved that multiple advertising platforms can obtain non-user sensitive information on the target user device based on the same advertising tracking identifier, and then perform user behavior analysis to portray user behavior portraits. For example, the advertising service platform generates an advertising tracking identifier 10110 for target user 1, and then the advertising service platform shares the advertising tracking identifier 10110 of target user 1 with other advertising service platforms, then other advertising service platforms can also find target user 1 based on the ID 10110.

It can be understood that the above two application scenarios are just several exemplary implementations in the embodiments of the present invention. The application scenarios in the embodiments of the present invention include but are not limited to the above application scenarios.

The embodiments of the present application are described below in conjunction with the accompanying drawings.

Based on the above-mentioned technical problems and the corresponding application scenarios in this application, and also to facilitate understanding of the embodiments of the present invention, the system architecture based on which the embodiments of the present invention are based is described below. Please refer to Figure 1A, which is a schematic diagram of a system architecture for advertising tracking provided by an embodiment of the present invention. The system is used to generate an advertising tracking ID that does not rely on user sensitive information to avoid user privacy leakage. The system architecture may include a client 101 and a server 102. Among them,

Client 101, in this application, refers to one or more application software (Application, APP) installed on the same device. APP refers to software installed on a smart phone, which improves the deficiencies and personalization of the original system of the smart phone and provides users with a richer user experience. For example, client 101 APP can be Taobao, WeChat, JD.com and other applications. With the popularization of the Internet, users will spend more time on different APPs, so placing advertisements in APPs has become the focus of advertising service providers. In the process of Internet advertising, client 101 can be used to send non-user sensitive information (such as device model, system version, APP installation list and other information) to server 102.

The server 102 in this application refers to an advertising service platform that pushes advertisements to target users. The server 102 includes an identifier generator 1021 and an information management platform 1022. Among them, the identifier generator 1021 is used to receive non-user sensitive information (such as device model, system version, APP installation list, etc.) sent by the client 101, and then process this information according to the identifier generation rules (such as hash algorithm) to generate an advertisement tracking identifier for the client 101. Then the client 101 can pull advertisements through the advertisement tracking identifier; the information management platform 1022 connects the buyer platform and the seller platform, and collects a large amount of media traffic by accessing the seller platform, thereby collecting and processing data belonging to the target customers of the advertisement.

For example, the client 101 is an APP, the server 102 is an advertising platform, the identifier generator 1021 is an advertising tracking identifier generator ID Generator, and the information management platform 1022 is an advertising trading platform Ad Exchange. See Figure 1B, which is a schematic diagram of another system architecture for advertising tracking provided by an embodiment of the present invention. In Figure 1B, the APP can send information including but not limited to device model, system version, language, country region, APP installation list (APP package name, APP name, APP installation time) to the ID Generator, and the ID Generator generates an advertising tracking ID based on this information. The App then pulls advertisements through the advertising tracking ID, and the Ad Exchange is used to provide it to the App to pull advertisements.

It can be understood that the advertisement tracking system architecture in FIG. 1A is only an exemplary implementation in the embodiment of the present application, and the advertisement tracking system architecture in the embodiment of the present application includes but is not limited to the above system architecture.

The specific method architecture on which the embodiment of the present invention is based is described below. Referring to Figure 2A, Figure 2A is a flow chart of a method for generating an advertising tracking identifier in an embodiment of the present application. The advertising tracking identifier generation method in the embodiment of the present application will be described from the interaction side between the server and the client in combination with Figure 2A and based on the advertising tracking system architecture in Figure 1A above. It should be noted that in order to describe the advertising tracking identifier generation method in the embodiment of the present application in more detail, the present application describes the corresponding execution subjects as the client or the server in each process step, but it does not mean that the embodiment of the present application can only perform the corresponding method flow through the described execution subjects.

Step 2011 and step 2012: M clients read the first device information from the advertising software development kit.

The first device information includes a first application installation list; the first application installation list includes the application package name, application name and installation time of the N applications installed on the client; the advertising software development kit is a software development kit provided by the server to the client; and N is greater than or equal to 1. It should be noted that for the installed applications in the application list, when they are not associated with an individual user, they are non-user sensitive information and do not involve user privacy. Specifically, the M clients are one or more application software on different devices. When developing the client, the advertising software development kit (such as advertising SDK) provided by the server can be added to the client. After that, the client can read some non-user sensitive information of the current device (such as the application list information on the device, etc.) through this advertising software development kit. At this time, the non-user sensitive information of the current device read by the client is the first device information mentioned above. For example, as shown in Figure 2B, Figure 2B is a schematic diagram of an application display interface provided by an embodiment of the present invention. In Figure 2B, there are devices 1 and 2. WeChat and Toutiao are installed on device 1, and both WeChat and Toutiao have advertising SDKs provided by the server; WeChat and Bilibili are installed on device 2, and both WeChat and Bilibili have advertising SDKs provided by the server. At this time, M is 2 and there may be two clients. Client 1 may be WeChat or Toutiao on device 1; client 2 may be WeChat or Bilibili on device 2. The first device information obtained by client 1 includes the application package name, application name, and installation time of WeChat installed on device 1, and the application package name, application name, and installation time of Toutiao. Optionally, the application installation time information can be accurate to milliseconds. The accuracy of obtaining the application installation time is high, which means that the possibility of the same non-user sensitive information obtained by different clients is small, and the generated advertising tracking identifier can more accurately distinguish different clients; the first device information obtained by client 2 includes the application package name, application name, and installation time of WeChat installed on device 2, and the application package name, application name, and installation time of Bilibili. Optionally, the application installation time information can be accurate to milliseconds.

In a possible implementation, the first device information also includes the device model, version, language country, operating system, and operating system version of the corresponding client; the first device information is obtained by the corresponding client from the advertising software development kit, and the advertising software development kit is a software development kit provided by the server to the corresponding client. Specifically, the first device information may also include the device model (such as Huawei Mate40 pro), version (such as EMUI 11), language country (such as Chinese, national version), operating system (such as Android), operating system version (such as Android11) and other information of the corresponding client device. In the embodiment of the present invention, since the advertising SDK provided by the server is installed in the client end, the client can read the first device information of the client device through this advertising SDK, and carry these first device information when the client sends an advertising tracking identifier request to the server, so that the server can generate the corresponding advertising tracking identifier according to these first device information. These first device information include the application package name, application name and installation time of multiple applications installed on the client device, and may also include the device model, version, language country, operating system, and operating system version of the client device. It should be noted that for the installed applications in the application list, when they are not associated with individual users, they are non-user sensitive information and do not involve user privacy. The more information that does not involve user privacy is included in the request, the less likely it is that there will be duplication when the ad tracking identifier is generated by the server, and the ad tracking identifier generated by the server can more accurately distinguish different clients.

Step 2021 and step 2022: M clients send advertising tracking identifier requests to the server.

The advertising tracking identifier request includes the first device information. Specifically, after the client obtains the first device information, it can send an advertising tracking identifier request to the server, which is used to instruct the server to generate an advertising tracking identifier that can distinguish different clients according to the first device information in the advertising tracking identifier request. For example, as shown in FIG2B, at this time, M is 2, there are 2 clients, and client 1 and client 2 can send advertising tracking identifier requests to the server respectively, and the advertising tracking identifier request of client 1 includes the first device information of device 1, wherein the first device information of device 1 may include the application package name, application name and application installation time of WeChat installed on device 1, the application package name, application name and application installation time of Toutiao, and may also include the device model, version, language country, operating system, operating system version, etc. of device 1; the advertising tracking identifier request of client 2 includes the first device information of device 2, wherein the first device information of device 2 may include the application package name, application name and application installation time of WeChat installed on device 2, the application package name, application name and application installation time of Bilibili, and may also include the device model, version, language country, operating system, operating system version, etc. of device 2.

Step 2030: The server receives M advertisement tracking identifier requests sent by M clients.

Among them, each of the M advertising tracking identification requests includes the first device information of the corresponding client; the first device information includes the first application installation list, and the first application installation list includes the application package name, application name and installation time of N applications installed on the corresponding client; the M is greater than or equal to 1; the N is greater than or equal to 1. Specifically, the server receives advertising tracking identification requests sent by M clients, and the advertising tracking identification requests include the first device information on the corresponding client device, and the first device information includes the application package name, application name and installation time of multiple applications installed on the client device. It should be noted that for the installed applications in the application list, when they are not associated with individual users, they are non-user sensitive information and do not involve user privacy. For example, as shown in Figure 2B, at this time M is 2, there are 2 clients, and the server receives the advertising tracking identification request sent by client 1 and client 2, wherein the advertising tracking identification request of client 1 includes the first device information of device 1; the advertising tracking identification request of client 2 includes the first device information of device 2, and the first device information of device 1 may include the application package name, application name, and installation time of WeChat installed on device 1, and the application package name, application name, and installation time of Toutiao of Toutiao. Optionally, the application installation time information can be accurate to milliseconds; the first device information of device 2 includes the application package name, application name, and installation time of WeChat installed on device 2, and the application package name, application name, and installation time of Bilibili. Optionally, the application installation time information can be accurate to milliseconds.

Step 2040: The server generates M first advertisement tracking identifiers according to the M pieces of first device information included in the M advertisement tracking identifier requests.

Each of the M first advertising tracking identifiers is used to identify the client under the corresponding first device information. Specifically, in response to the advertising tracking identifier requests sent by the M clients, the server uses the same identifier generation rule to process the non-user sensitive information in each advertising tracking identifier request to generate a corresponding advertising tracking identifier. Optionally, the identifier generation rule used by the server when generating the advertising tracking identifier may be a hash algorithm. The hash algorithm is to transform an input of any length (also called pre-mapping) into an output of a fixed length through a hash algorithm. The server uses the hash algorithm to take the first device information in the advertising tracking identifier request as input, thereby generating a first advertising tracking identifier. For example, as shown in FIG. 2C, FIG. 2C is a schematic diagram of an advertising tracking identifier generation algorithm provided by an embodiment of the present invention. In FIG. 2C, the server uses the first device information in the advertising tracking identifier request sent by client 1 and the first device information in the advertising tracking identifier request sent by client 2 as inputs of the hash algorithm, and then generates a first advertising tracking identifier (such as 110010) for identifying client 1 and a first advertising tracking identifier (such as 101011) for identifying client 2, respectively.

Step 2051 and step 2052: the server returns each first advertisement tracking identifier to the corresponding client.

Specifically, after the server responds to the advertising tracking identifier request sent by M clients, it generates M corresponding first advertising tracking identifiers, and then the server sends a corresponding session response to the M clients, and the session response includes the advertising tracking identifier of the corresponding client. For example, the server generates a first advertising tracking identifier (such as 110010) based on the first device information in the advertising tracking identifier request sent by client 1, and then the server returns the first advertising tracking identifier 110010 to client 1. The server generates a first advertising tracking identifier (such as 101011) based on the first device information in the advertising tracking identifier request sent by client 2, and then the server returns the first advertising tracking identifier 101011 to client 2. It should be noted that since the device information of client 1 and client 2 is different, the generated advertising tracking identifiers must be different.

In a possible implementation, the method further includes the server storing the mapping relationship between each first advertisement tracking identifier and the corresponding first device information in an identification database. Specifically, after the server responds to the advertisement tracking identifier requests sent by M clients, M corresponding first advertisement tracking identifiers are generated, and the mapping relationship between each first advertisement tracking identifier and the corresponding first device information can be stored in the identification database. For example, as shown in FIG2D, FIG2D is a schematic diagram of a server identification database provided by an embodiment of the present invention. In FIG2D, when the server generates corresponding first advertisement tracking identifiers according to the first device information provided by client 1 and client 2, such as the first advertisement tracking identifier of client 1 is 110010, and the first advertisement tracking identifier of client 2 is 101011. Then the service stores the mapping relationship between the first device information of client 1 and the first advertisement tracking identifier 110010 and the mapping relationship between the first device information of client 2 and the first advertisement tracking identifier 101011 in the identification database. In an embodiment of the present invention, after the server responds to the M advertisement tracking identifier requests, M advertisement tracking identifiers are generated. The server stores the mapping relationship between these M advertising tracking identifiers and the corresponding non-user sensitive information in the identification database, so that the server can subsequently characterize user portraits according to the mapping relationship between these advertising tracking identifiers and the corresponding non-user sensitive information. At the same time, after the server generates the advertising tracking identifier, the advertising tracking identifier can be compared with the advertising tracking identifiers already existing in the identification database to determine whether the same advertising tracking identifier is generated, thereby avoiding the situation where multiple clients correspond to the same advertising tracking identifier, thereby protecting user privacy while enabling the server to distinguish different clients more accurately.

In a possible implementation, after the server responds to the advertising tracking identifier request, the client receives the first advertising tracking identifier returned by the server, and stores the mapping relationship between the first advertising tracking identifier and the first device information in a local database; the first advertising tracking identifier is generated by the server according to the first device information and is used to identify the client under the first device information. Specifically, after the client receives the first advertising tracking identifier sent by the server, the client stores the mapping relationship between the first advertising tracking identifier and the corresponding first device information in the local database, so as to facilitate the subsequent server to find the client. For example, as shown in FIG2D , the first advertising tracking identifier sent by the server received by client 1 is 110010, and then client 1 stores the mapping relationship between the first device information of client 1 and the first advertising tracking identifier 110010 in the local database of client 1; the first advertising tracking identifier sent by the server received by client 2 is 101011, and client 2 stores the mapping relationship between the first device information of client 2 and the first advertising tracking identifier 101011 in the local database of client 2.

In a possible implementation, the method further includes: the server sends the mapping relationship between each first advertising tracking identifier and the corresponding first device information stored in the identification database to the third-party platform. Specifically, the third-party platform includes other advertising service providers. For example, as shown in FIG2D , the server may send the mapping relationship between the first device information of client 1 and the first advertising tracking identifier 110010, and the mapping relationship between the first device information of client 2 and the first advertising tracking identifier 101011 in the identification database of the server in FIG2D to other third-party advertising service platforms. In an embodiment of the present invention, the server may send the mapping relationship between the advertising tracking identifier and the corresponding non-user sensitive information stored in the identification database to other third-party platforms, and the other third-party platforms may perform user profiling based on these mapping relationships in combination with platform requirements, and the other third-party platforms may find the corresponding client based on the advertising tracking identifiers in these mapping relationships.

Different from the prior art in which the client generates the ad tracking ID, in the embodiment of the present invention, the server uniformly generates the ad tracking IDs of various clients, and the server avoids the problem of user privacy leakage caused by using the ad tracking ID generated by the client according to the user sensitive information, and also avoids the problem of being unable to uniformly manage the ad tracking IDs of different types of clients due to different rules for generating ad tracking IDs by different types of clients. Instead, the server uniformly generates an ad tracking identifier with a unified rule for each client according to some non-user sensitive information provided by different clients, and then uses the ad tracking identifier to identify the corresponding client, so that the ad tracking identifier that can accurately distinguish different clients can be generated without relying on user sensitive information and the client operating system. Specifically, after receiving the ad tracking identifier request sent by M clients, the server responds to the M ad tracking identifier requests and uses the same identifier generation rule to process the non-user sensitive information in each ad tracking identifier request to generate a corresponding ad tracking identifier, and the non-user sensitive information includes the application package name, application name and installation time of multiple applications installed by the user on the client device. Next, the server sends a corresponding session response to the M clients, and the session response includes the ad tracking identifier of the corresponding client. Through the embodiments of the present invention, the server does not rely on user privacy information and the client operating system to generate an advertising tracking identifier, and then the server can use the advertising tracking identifier generated by itself to identify multiple clients, thereby protecting user privacy while enabling the server to more accurately distinguish different clients.

In order to describe the embodiment of the present invention in more detail, after the steps in FIG. 2A above, the embodiment of the present invention may also include a process for updating the client advertising identifier, see FIG. 3A, FIG. 3A is a flowchart of another method for generating an advertising tracking identifier in the embodiment of the present application, and the following will be combined with FIG. 3A and based on the advertising tracking system architecture in FIG. 1A above, the advertising tracking identifier generation method in the embodiment of the present application will be described from the interaction side between the server and the client. It should be noted that in order to describe the advertising tracking identifier generation method in the embodiment of the present application in more detail, the present application describes the corresponding execution subject as the client or the server in each process step, but it does not mean that the embodiment of the present application can only perform the corresponding method flow through the described execution subject.

Step 3011 and step 3012: M clients respond to the request to start the client, start the client and read the current application installation list on the client.

The current application installation list includes the application package names, application names and installation time of the S applications currently installed by the client; S is greater than or equal to 1. It should be noted that for the applications installed in the application list, when they are not associated with the user, they are non-user sensitive information and do not involve user privacy. Specifically, M clients start the client in response to the client start request, and the client reads the application installation list on the current device through the advertising SDK. Since the user can install or uninstall software applications on the device, the application installation list on the device may change. For example, as shown in Figure 3B, Figure 3B is a schematic diagram of a device application change interface provided by an embodiment of the present invention. In Figure 3B, WeChat and Toutiao applications are installed on device 1, but after the first advertising tracking identifier is generated, a new Youku application is installed on device 1. When client 1 is opened again, the current application installation list obtained by client 1 is the application package name, application name and application installation list of WeChat, Youku and Toutiao.

Step 3021 and step 3022: M clients determine whether the application package names, application names and installation times of the N applications in the first application installation list are the same as the application package names, application names and installation times of the S applications in the current application installation list.

Specifically, after each of the M clients reads the application installation list of the current device, it is determined whether the current application installation list is the same as the application installation list previously stored in the local database. For example, when client 1 requests to generate the first advertising tracking identifier, the software applications installed on device 1 are WeChat and Toutiao, but after client 1 receives the first advertising tracking identifier, the user downloads Youku on device 1, and the application installation list on device 1 changes. However, when client 2 requests to generate the first advertising tracking identifier, the software applications installed on device 2 are WeChat and Bilibili, and after client 2 receives the first advertising tracking identifier, the application of device 2 does not change, so the application installation list of device 2 does not change. For another example, when client 1 requests to generate the first advertising tracking identifier, the software applications installed on device 1 are WeChat and Toutiao, but after client 1 receives the first advertising tracking identifier, the user uninstalls the previously installed WeChat on device 1 and re-downloads WeChat. Since the installation time of WeChat changes, the application installation list on device 1 also changes.

Step 3030: If the application package names, application names and installation times of the N applications in the first application installation list on the L clients are different from the application package names, application names and installation times of the S applications in the current application installation list, then the current application installation list is the second application installation list, and a request to update the advertising tracking identifier is sent to the server.

The request to update the ad tracking identifier includes the second device information; the second device information includes the second application installation list. Specifically, when L of the M clients determine that the application installation list of the current device is different from the application installation list previously stored locally, they send a request to update the ad tracking identifier to the server, and carry the second device information (current device information) in the request to update the ad tracking identifier. For example, when M is 2, there are client 1 and client 2. If client 1 determines that the application list information of device 1 has changed, but client 2 determines that the application list information of device 2 has not changed, client 1 can send a request to update the ad tracking identifier to the server, and carry the second device information (non-user sensitive information of the current device 1) in the request, where the second device information includes the application package name, application name and application installation time of the application installed on the current device.

In a possible implementation, the second device information also includes the device model, version, language country, operating system, and operating system version of the corresponding client; the second device information is obtained by the corresponding client from the advertising software development kit. Specifically, since the advertising SDK provided by the server is installed in the client, the client can obtain some non-user sensitive information of the current client device through this advertising SDK, and carry these current non-user sensitive information when the client sends a request to update the advertising tracking identifier to the server, so that the subsequent server can generate the corresponding advertising tracking identifier according to these current non-user sensitive information. These current non-user sensitive information includes the application package name, application name and installation time of multiple applications currently installed on the client device, and may also include the device model (such as Huawei Mate40 pro), version (such as EMUI 11), language country (such as Chinese, national version), operating system (such as Android), and operating system version (such as Android11) of the client device. It should be noted that for the installed applications in the application list, when there is no associated user individual, it is non-user sensitive information and does not involve user privacy. The more information not involving user privacy is included in the request, the less likely it is that duplication will occur when the ad tracking identifier is generated by the server, and thus the ad tracking identifier generated by the server can more accurately distinguish different clients.

Step 3040: The server receives L advertisement tracking identifier update requests from L clients among the M clients.

Among them, each of the L requests for updating the advertising tracking identifier includes the second device information of the corresponding client; the second device information includes a second application installation list, and the second application installation list includes the application package name, application name and installation time of S applications installed on the corresponding client; the L is greater than or equal to 1; the S is greater than or equal to 1. It should be noted that for the applications installed in the application list, when they are not associated with an individual user, they are non-user sensitive information and do not involve user privacy. Specifically, the server receives the request for updating the advertising tracking identifier sent by L clients, and the request for updating the advertising tracking identifier includes the second device information on the corresponding client device. The second device information includes the application package name, application name and installation time of multiple applications currently installed on the client device, so that the server can subsequently generate a new advertising tracking identifier based on the current device information. For example, the request to update the advertising tracking identifier of client 1 includes the second device information of device 1, where the second device information of device 1 may include the application package name, application name and application installation time of WeChat installed on device 1, the application package name, application name and application installation time of Toutiao, the application package name, application name and application installation time of Youku, and may also include the device model, version, language country, operating system, operating system version, etc. of device 1.

Step 3050: The server generates L second advertisement tracking identifiers according to the L second device information included in the L update advertisement tracking identifier requests.

Each of the L second advertising tracking identifiers is used to identify the client under the corresponding second device information. Specifically, in response to the update advertising tracking identifier request sent by the L clients, the server uses the same identifier generation rule to process the non-user sensitive information in each update advertising tracking identifier request to generate a corresponding advertising tracking identifier. Optionally, the identifier generation rule used by the server when generating the advertising tracking identifier can be a hash algorithm. The hash algorithm is to transform an input of any length (also called pre-mapping) into an output of a fixed length through a hash algorithm. The server uses the hash algorithm to take the second device information in the update advertising tracking identifier request as input to generate the second advertising tracking identifier. For example, the first advertising tracking identifier of client 1 is 110010, but because the user's application installation list on device 1 has changed (such as installing a new application or uninstalling the current application, etc.), the client sends an update advertising tracking identifier request to the server. After the server responds to the update advertising tracking identifier request, it generates a second advertising tracking identifier of 100001 according to the second device information.

Step 3060: The server determines whether there is an identifier identical to the L second advertisement tracking identifiers in the identifier database.

Specifically, when the server generates L new advertising tracking identifiers in response to the advertising tracking identifier update requests from L clients, the server compares the L new advertising tracking identifiers with the advertising tracking identifiers stored in the identifier database, thereby avoiding the situation where the same advertising tracking identifier corresponds to multiple clients under abnormal circumstances, thereby dynamically updating the advertising tracking identifier of the client and enabling the server to accurately distinguish different clients under abnormal circumstances. For example, the new advertising tracking identifier of client 1 is 100001, as shown in FIG2D , and the server will determine whether 100001 is the same as 110010 and 101011 in the identifier database.

Step 3070: If there is no identifier identical to the L second advertisement tracking identifiers in the identifier database, the server returns each of the second advertisement tracking identifiers to the corresponding client.

Specifically, when the L new advertisement tracking identifiers are compared with the advertisement tracking identifiers stored in the identifier database, if no identical advertisement tracking identifiers appear, the server returns each new advertisement tracking identifier to the corresponding client. For example, the new advertisement tracking identifier of client 1 is 100001, as shown in FIG2D , and the server can determine whether 100001 is identical to 110010 and 101011 in the identifier database. If not, the server can return the second advertisement tracking identifier 100001 of client 1 to client 1.

In a possible implementation, each of the L requests for updating the advertising tracking identifier also includes the first advertising tracking identifier of the corresponding client; the method further includes: storing the mapping relationship between each second advertising tracking identifier and the corresponding second device information in the identification database, and associating the second advertising tracking identifier corresponding to the same client with the first tracking identifier. Specifically, when the client sends the request for updating the advertising tracking identifier to the server, the request for updating the advertising tracking identifier carries the current advertising tracking identifier (first advertising tracking identifier) of the corresponding client. After the server responds to these requests for updating the advertising tracking identifier, it stores the mapping relationship between each new advertising tracking identifier and the corresponding current non-user sensitive information in the identification database, and associates the current advertising tracking identifier of the same client with the new advertising tracking identifier. If the server finds that the new advertising tracking identifier is associated with other advertising tracking identifiers when describing the user portrait according to the mapping relationship between the new advertising tracking identifier and the corresponding current non-user sensitive information, the user portrait features corresponding to the associated advertising tracking identifier are added to the new user portrait, so that the server can deliver personalized advertisements more accurately. For example, as shown in FIG. 3C , FIG. 3C is a schematic diagram of another server identification database provided in an embodiment of the present invention. In FIG. 3C , when the server generates a second advertising tracking identifier for client 1, a mapping relationship between the second device information and the second advertising tracking identifier is stored in the identification database. If the first advertising tracking identifier is carried in the update advertising tracking identifier request of client 1, the first advertising tracking identifier is associated with the second advertising tracking identifier.

In a possible implementation, the mapping relationship between each second advertising tracking identifier and the corresponding second device information stored in the identification database is sent to the third-party platform. In an embodiment of the present invention, when the advertising tracking identifier of the client changes, the server can send the mapping relationship between the new advertising tracking identifier stored in the identification database and the corresponding current non-user sensitive information to other third-party platforms, and other third-party platforms can perform user profiling based on these mapping relationships in combination with platform requirements, and other third-party platforms can find the corresponding client based on the new advertising tracking identifier in these mapping relationships. For example, the server can send the mapping relationship between the second device information of client 1 and the second advertising tracking identifier 100001 to other third-party platforms, and other third-party platforms can perform user profiling based on the second device information in the mapping relationship, and then use the 100001 identifier to identify the user portrait, and find the corresponding client through the identifier 100001.

Step 3080: L clients delete the mapping relationship between the first advertisement tracking identifier and the first device information stored in the local database, and store the mapping relationship between the second advertisement tracking identifier and the second device information in the local database.

After the server responds to the request to update the advertisement tracking identifier, the server receives a second advertisement tracking identifier returned by the server, where the second advertisement tracking identifier is generated by the server according to the second device information and is used to identify the client under the second device information. Specifically, when the server generates a new advertisement tracking identifier in response to the request to update the advertisement tracking identifier, and returns the new advertisement tracking identifier to the corresponding client, the client receives the new advertisement tracking identifier and saves the mapping relationship between the new advertisement tracking identifier and the corresponding current non-user sensitive information in a local database, and then deletes the mapping relationship between the advertisement tracking identifier and the corresponding non-user sensitive information previously stored in the local database, thereby realizing dynamic updating of the advertisement tracking identifier by the client. For example, as shown in FIG3D , FIG3D is a schematic diagram of a client local database provided by an embodiment of the present invention. In FIG3D , the client 1 deletes the mapping relationship between the first device information and the first advertisement tracking identifier previously stored in the local database. If the client 1 receives the mapping relationship between the second device information and the second advertisement tracking identifier sent by the service, the mapping relationship between the second device information and the second advertisement tracking identifier is stored in the local database.

In the embodiment of the present invention, the server does not use the advertising tracking ID provided by the client to distinguish different clients, but generates an advertising tracking identifier based on some non-user sensitive information provided by the client, and then uses the advertising tracking identifier to identify the corresponding client, thereby being able to generate an advertising tracking identifier that can accurately distinguish different clients without relying on user sensitive information and the client operating system, and can dynamically update the advertising tracking identifier of the client. Even if the illegal elements obtain the advertising tracking identifier of the client, the identifier will change, so the illegal elements cannot always find the same client through one advertising tracking identifier, which can better protect user privacy.

Taking the client as an APP and the server as an advertising platform as an example, see FIG4 , which is a schematic diagram of an exemplary flow chart of a method for generating an advertising tracking identifier provided by an embodiment of the present invention.

Step 1: The APP requesting the advertisement reads the device model, version, language country, and APP installation list information (including but not limited to these information). It should be noted that for the installed applications in the application list, when there is no association with the user, it is non-user sensitive information and does not involve user privacy.

Step 2: The APP requesting the advertisement initiates a request to the ID Generator to obtain the advertisement tracking ID, and carries the device model, version, language country, and APP installation list information (including but not limited to these information) that has been read in the request.

Step 3: ID Generator searches for the same user based on the parameters in the request. The search method may be to perform a hash algorithm operation, such as Sha256 hash algorithm, on the parameters of device model, version, language country, and APP installation list information (including but not limited to) to generate an ID. The ID is then used to search for the ID Generator's internal storage to determine if the ID exists. If the ID exists, it indicates that the same user exists.

Step 4: If the same user does not exist, the ID Generator generates a new ad tracking ID using the hash algorithm mentioned in step 3.

Step 5. The ID Generator server stores the mapping relationship between the new ad tracking ID and parameters such as device model, version, language country, and APP installation list information.

Step 6: The APP requesting the advertisement also stores the mapping relationship between the new advertisement tracking ID and the device model, version, language country, and APP installation list information.

Step 7: Each time the user enters the APP, the latest installation list information of the APP is obtained.

Step 8: The APP determines whether the APP installation list of the device has changed (change means a new APP is installed or an APP is uninstalled).

Step 9. If the APP installation list of this device has changed, the current APP will request the ID Generator to update the ad tracking ID (by querying the ID Generator with the device model, version, language and country, and the updated APP installation list information). It should be noted that for the installed applications in the application list, when they are not associated with the user, they are non-user sensitive information and do not involve user privacy.

Step 10, ID Generator searches whether the same user already exists. The search method may be to perform a hash algorithm operation, such as the Sha256 hash algorithm, on the device model, version, language and country, and APP installation list information (including but not limited to) to generate an ID. The ID is then used to search for the ID Generator's internal storage to determine whether the ID exists. If the ID exists, it indicates that the same user exists.

Step 11: If the same user does not exist, the ID Generator generates a new ad tracking ID using the hash algorithm mentioned in step 10.

Step 12: The ID Generator server stores the mapping relationship between the new ad tracking ID and parameters such as device model, version, language country, and APP installation list information.

Step 13. The App also stores the mapping between the new ad tracking ID and parameters such as device model, version, language country, and App installation list information.
