Method For Managing User Identifier And Software Development Kit Including The Same}

The present invention relates to a method for managing a user identification value in a software development kit and the software development kit, and more specifically, to a method for managing a user identification value in a terminal, comprising the steps of: (a) activating a first application; (b) searching for an identification value stored in the first application; and (c) requesting an advertisement by transmitting the stored identification value to an advertisement server, wherein the identification value is stored to be the same in all applications in the terminal.

With the development of communication networks and the development of terminal specifications, communication terminals have gone beyond the scope of conventional simple communication devices or information provision devices and have become essential belongings of modern people, and are evolving into total entertainment devices. Additionally, communication terminals that can use the Internet provide content such as advertising, finance, entertainment, news, and community in various fields.

In particular, most of the online advertising delivery methods that have been in the spotlight recently are carried out through terminals. Accordingly, online advertising began in the form of random advertisements being exposed to inventory within the medium. However, as the number of advertisers who want to sell advertisements and publishers who want to sell inventory, which is the space where advertisements will be placed, increases, advertising agency servers appear to relay between advertisers and publishers, and advertisers' advertisements are randomly placed on the publisher's inventory. Starting with the exposure method, targeting advertising technology has now developed into a form of exposing selected advertisements based on user visit information.

Here, the medium through which advertisements are exposed to users is called media, and the space within the medium where advertisements are exposed is called inventory. At this time, if the medium is in the form of an application, it is called in-application (in-app), and if the medium is in the form of a website, it is called mobile web (m-web). Additionally, the method of selecting advertisements that are likely to be of high interest based on the user's unique information is called targeting.

Meanwhile, as shown in Figure 1, in an in-app advertising service that serves advertisements using an application as a medium, identification of the user or terminal requesting the advertisement is essential in order to transmit advertisements targeted to a specific user.

For this purpose, in the past, the user's phone number, the device's unique identification value, and the platform's unique identification value were used as a method to identify the user or terminal, as shown in Figure 2. However, due to privacy protection issues, the corresponding values are gradually being used. This has been restricted under legal/platform policies. In other words, there is a limitation that prevents the use of unique values created during the production process of the device or unique values that can represent an individual.

To avoid this problem, there is a method of generating and continuously managing random values without using unique values of the device or individual, and these values are meaningful only if they are commonly used in multiple applications installed within the same terminal. In other words, the fact that multiple applications installed in the same terminal have different identification values has no meaning in targeting advertising. Therefore, as shown in Figure 3, a method of sharing and using these identification values in multiple applications through external storage such as SD cards has been used in the past, but access to external storage such as SD cards has been restricted due to recently strengthened platform policies. has emerged and it has become difficult to use conventional technology anymore.

The present invention was invented based on this technical background, and was invented to not only meet the technical needs discussed above, but also to provide additional technical elements that cannot be easily invented by those skilled in the art.

Below, before explaining the present invention, the concepts and terms of targeting and retargeting in the field of the present invention will be explained.

In the first form of online advertising, advertisers and publishers traded advertisements and inventory directly without an advertising agency server, but as the number of internet users increased, the effectiveness of internet advertising increased rapidly, and advertisers who wanted to sell advertisements and the space where advertisements would be placed were created. There are a lot of publishers wanting to sell their inventory. Accordingly, advertising agency servers emerged that handle advertising and inventory transactions between advertisers and publishers. This method is a method in which random advertisements are exposed to inventory within the media, and then retargeting is performed by identifying users based on the user's visit information and selecting and displaying advertisements based on the user's information. Advertisements were developed.

Retargeting advertising is a form of advertising that increases advertising effectiveness by encouraging the advertiser to visit interested users with a relatively high conversion rate through marketing activities such as search advertising, and then exposing images of products of particular interest to the visiting users through retargeting media. It's an advertisement. This is not simply a form of advertisement that pops up or appears manually when visiting a website, but is instead a DSP (Demand Side Platform) server that sells advertisements and purchases inventory where advertisements will be displayed, and finds appropriate inventory to display advertisements on behalf of advertisers. , through information linkage between publishers who sell inventory where advertisements will be displayed and SSP (Supply Side Platform) servers that find advertisements to be displayed on behalf of publishers, advertising target users are identified and identified based on user age, preference, and advertisement type. It is a system that sends advertisements to user terminals.

At this time, the DSP server generates retargeting advertisements with targeting information for each user in advance through data analysis of information on viewing specific pages within the website visited by the user, shopping cart details, login information, etc. of the visiting user. Afterwards, a retargeting advertising service is provided in the form of classifying the nature of the registered advertisement according to targeting information, and transmitting advertisements classified according to the user's targeting information when detecting that the user has accessed the publisher's site.

Accordingly, the terms used in the present invention are defined as follows.

Retargeting Ads refers to providing products to users who have visited the advertiser's website or viewed a specific page within the website, even if they accessed another website. Or, it refers to a method of re-showing advertisements for services.

At this time, targeting information refers to information used to select advertisements by considering the actions taken within the advertiser's website by users who visit the advertiser's website. Therefore, targeting information may include information on viewing a specific page within a website visited by the user, shopping cart details, login information, etc. of the visited user.

Media refers to the medium through which advertisements are exposed to users. For example, means through which advertisements can be exposed include TV, radio, and the Internet. Since the present invention targets retargeting advertisements online, the Internet can be a medium.

Inventory refers to the space within the medium where advertisements are exposed. In the case of the Internet, inventory may be a specific space on a website for displaying advertisements.

An advertiser is a person who wishes to purchase inventory on which advertisements will be displayed in order to display advertisements that he or she owns.

A publisher is a person who holds inventory in a medium that can display advertisements.

A DSP (demand side platform) server is a server managed by a business operator that searches for appropriate inventory to expose advertisements on behalf of advertisers.

An SSP (supply side platform) server is a server managed by a business operator who sells inventory on behalf of a publisher and searches for advertisements to display.

At this time, if the medium is in the form of an application, it is called in-application (in-app), and if the medium is in the form of a website, it is called mobile web (m-web). Additionally, the method of selecting advertisements that are likely to be of high interest based on the user's unique information is called targeting.

Meanwhile, in the in-app advertising service that serves advertisements using applications as a medium, identification of the user or terminal requesting the advertisement is essential in order to transmit advertisements targeted to specific users.

Figure 2 is a diagram for explaining a conventional method for identifying a user or terminal.

Referring to Figure 2, the user's phone number, device's unique identification value, platform's unique identification value, etc. have been used to identify the user or terminal, but legal/platform regulations are gradually preventing the use of such values due to privacy protection issues. has been suppressed under the policy. In other words, there is a limitation that prevents the use of unique values created during the production process of the device or unique values that can represent an individual.

To avoid this problem, there is a method of generating and continuously managing random values without using the device's or individual's unique values, but these values are meaningful only when they are commonly used in multiple applications installed within the same terminal. Therefore, it is meaningless for multiple applications installed in the same terminal to have different identification values.

Figure 3 is a diagram illustrating a method for sharing identification values between multiple applications through external storage such as a conventional SD card.

Referring to Figure 3, a method was used to share and use these identification values in multiple applications through external storage such as an SD card. However, recently strengthened platform policies have created restrictions on access to external storage such as SD cards, and the method shown in Figure 2 is no longer difficult to use.

Accordingly, the present invention proposes a method to ensure that all applications installed in the same terminal have the same identification value, thereby enabling user targeting and re-targeting advertisements.

Figure 4 is a diagram for explaining a method for managing user identification values in a terminal according to an embodiment of the present invention.

Referring to Figure 4, in the present invention, each application stores an advertisement identification value in its own identification value storage unit. And these advertisement identification values are synchronized so that they have the same value in each application, so that the identification values in each application within the same terminal have the same value.

Unlike before, the identification value required for user-targeted advertisement requests uses the identification value stored in the identification value storage of each application.

Here, the identification value storage is a storage space inside each application installed on the terminal. Unlike external storage, which requires clear consent from the user to access permissions, it is a unique space for individual applications and does not require separate permissions for access. Therefore, the present invention can enable user targeting and re-targeting advertisements by synchronizing the identification value storage units of applications installed in the same terminal so that they all have the same identification value.

Meanwhile, a method of synchronizing identification values between applications can utilize the IPC mechanism provided by the operating system or platform. For example, on the Android platform, you can utilize the Broadcast Receiver function. The Broadcast Receiver system provides the ability to simultaneously broadcast commands and some parameters to applications that have declared to receive events for specific commands.

FIG. 5 is a diagram illustrating a method for managing user identification values in a software development kit (SDK) according to an embodiment of the present invention.

A software development kit is a set of development tools that allow software engineers to create applications for a specific software package, software framework, hardware platform, computer system, gaming console, operating system, etc.

Some files that are intended to connect to a specific programming language or contain complex hardware that communicates with a specific embedded system can be simply notated as an application programming interface (API). Common tools include debugging aids and other utilities in the form of an integrated development environment (IDE). Software development kits also provide users with clear key points by providing technical notes or support documentation, including sample code.

Referring to FIG. 5, a method of managing a user identification value in a software development kit according to an embodiment of the present invention includes the steps of (a) activating a first application; (S410); (b) retrieving the identification value stored in the first application (S420); and (c) requesting an advertisement by transmitting the stored identification value to an advertisement server (S430). The identification value may be stored identically in all applications within the terminal.

The step (a) (S410) is a step in which the application is activated, and the application can be executed according to the user's input. Of course, the application may already be running in the background, but here, activation of the application means a state in which the user can directly view information about the application on the display screen. Meanwhile, the background state refers to a state in which an application is running, but is not directly visible on the display, occupies space in flash memory, and execution of the application is maintained.

In step (b) (S420), the first application can search for an identification value stored in the internal storage (hereinafter referred to as ‘identification value storage unit’ in the present invention). Here, the identification value storage is a storage space inside each application installed on the terminal. Unlike external storage such as an SD card that requires clear permission consent from the user, it is a space unique to each application and does not require separate permissions for access. Therefore, the present invention can enable user targeting and re-targeting advertisements by synchronizing the identification value storage units of applications installed in the same terminal so that they all have the same identification value.

Accordingly, in step (c) (S430), when the stored identification value is searched, the stored identification value is transmitted to the advertisement server to request an advertisement. The advertising server recognizes who the user is based on the received identification value and can target advertisements based on cookie data from the site that the user is interested in. Therefore, in the in-app advertising service that serves advertising using an application as a medium, identification of the user or terminal requesting advertising to a specific user is essential.

Therefore, it is important to ensure that all applications installed in the terminal have the same identification value. Therefore, the following describes how identification values are synchronized.

As another example of a method for managing a user identification value in a software development kit according to the present invention, when there is no identification value stored in the first application, step (b) (S420) includes (b-1) a new identification value. A step of matching and generating a stamp (timestamp) (S440); (b-2) transmitting the new identification value to a second application and querying whether there is an older timestamp (S450); and (b-3) receiving and storing an older identification value determined by the second application (S460).

In step (b-1) (S440), a new identification value can be created by matching a timestamp. This is to determine which one was created first when comparing identification values received from the application later. . Since no application will have an identification value when the terminal is initialized, there is no identification value to compare when the first identification value is created, so the first identification value created ensures that all applications of the terminal have the same identification value. It becomes a standard.

Here, a timestamp is metadata that stores the time or order of when the identification value was created, along with the identification value.

(b-2) In step S450, the new identification value is transmitted to the second application to query whether there is a timestamp older than the new identification value. At this time, the first application refers to an application activated in the terminal, and the second application refers to other applications. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. After receiving this, the second application compares it with the identification value it stored and transmits an identification value that was created a long time ago. The comparison process performed in the second application will be described in detail later with reference to FIG. 5.

(b-3) In step S460, the identification value matching the older timestamp compared in the second application is received and stored. Therefore, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the first application will re-receive and store the identification value generated by itself, and the identification value stored in the second application will be stored. If the identification value is older, the older identification value stored in the second application is received, stored in the first application identification value storage, and transmitted to the advertisement server.

FIG. 6 is a diagram illustrating a method for managing user identification values in a software development kit according to an embodiment of the present invention, and explains how a second application that receives a query from a first application compares identification values.

Referring to FIG. 6, in the method for managing user identification values in a software development kit according to an embodiment of the present invention, after step (b-2), the second application receives the identification value matched with the timestamp from the first application. Receiving (S510); Comparing the received identification value with an identification value stored in the second application to select an identification value created earlier (S520); and storing the identification value matched with the older timestamp and transmitting it to the first application (S530).

In step S510, where the second application receives an identification value matching the timestamp from the first application, an identification value newly generated by the first application that does not have a stored identification value is received. The first application refers to an application that is active in the terminal, and the second application refers to another application that has received a query for an identification value from the first application. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

In the step (S520) where the second application compares the identification value received from the first application and the identification value stored in the second application to select an identification value that was created earlier (S520), the time that was generated by matching at the time the identification value was created Through the stamp, it is possible to determine which identification value was created more recently. Accordingly, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the second application retransmits the identification value sent by the first application and transmits the identification value received from the first application. will be stored, and if the identification value stored in the second application is older, the older identification value stored in the second application will be transmitted to the first application, and the first application will transmit the identification value received from the second application. will be saved.

Accordingly, the second application selects the identification value created a long time ago, stores the identification value that matches the older timestamp, and transmits it to the first application (S530), and in this way, all the identification values installed in the terminal are stored. Identification values between applications are equally synchronized, and the synchronized identification values are transmitted to the ad server to receive targeted advertisements.

Meanwhile, the following describes the user identification value management software development kit from the device perspective.

Figure 7 is a diagram for explaining the configuration of a user identification value management software development kit according to an embodiment of the present invention.

Referring to FIG. 7, in the software development kit (SDK) provided in each application in the terminal, the user identification value management software development kit according to an embodiment of the present invention is an identification that stores the identification value. value storage unit 110; If there is no identification value stored in the identification value storage unit 110, an identification value generator 120 that generates an identification value that specifies the terminal; and an advertisement request unit 130 that requests an advertisement by transmitting the stored identification value to the advertisement server.

The identification value storage unit 110 is a storage space inside each application installed on the terminal. Unlike external storage such as an SD card that requires clear access permission consent from the user, the identification value storage unit 110 is a space unique to each application and requires separate permission for access. don't do it Therefore, the present invention can enable user targeting and re-targeting advertisements by synchronizing the identification value storage unit 110 of applications installed in the same terminal so that they all have the same identification value. there is.

The identification value generation unit 120 may generate a new identification value when there is no identification value stored in the identification value storage unit 110. Since no application will have an identification value when the terminal is initialized, there is no identification value to compare when the first identification value is created, so the first identification value created ensures that all applications of the terminal have the same identification value. It becomes a standard.

At this time, the identification value generator 120 may generate the identification value by matching it with a timestamp. Here, a timestamp is metadata that stores the time or order of when the identification value was created, along with the identification value. Therefore, when comparing the identification values received from the application later, it is possible to determine which one was created first through the timestamp.

If there is a stored identification value, the advertisement request unit 130 transmits the stored identification value to the advertisement server to request an advertisement. The advertising server recognizes who the user is based on the received identification value and can target advertisements based on cookie data from the site that the user is interested in. Therefore, in the in-app advertising service that serves advertising using an application as a medium, identification of the user or terminal requesting advertising to a specific user is essential.

In another embodiment of the present invention, if there is no identification value stored in the identification value storage unit 110, the generated identification value is transmitted to another application, and the identification value selected from the identification value comparison unit 150 of the other application is transmitted. An identification value transmitting and receiving unit 140 that receives and stores the value; And when an identification value is received from another application, an identification value that compares the received identification value with the identification value stored in the identification value storage unit 110 to select an identification value created earlier and retransmits it to the other application. It may further include a comparison unit 150.

When there is no identification value stored in the identification value storage unit 110, the identification value transmitting and receiving unit 140 transmits the new identification value to the second application and queries whether there is a timestamp older than the new identification value. At this time, the first application refers to an application activated in the terminal, and the second application refers to other applications. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. The identification value comparison unit 150 of the second application compares the identification value stored in the identification storage unit of the second application and transmits an identification value that was created a long time ago.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. After receiving this, the second application compares it with the identification value it stored and transmits an identification value that was created a long time ago.

The identification value comparison unit 150 of the second application receives the identification value matched with the timestamp from the first application, and determines which identification value was created earlier through the timestamp that was matched at the time the identification value was created. You can judge. Accordingly, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the second application retransmits the identification value sent by the first application and transmits the identification value received from the first application. will be stored, and if the identification value stored in the second application is older, the older identification value stored in the second application will be transmitted to the first application, and the first application will transmit the identification value received from the second application. will be saved.

Accordingly, the second application selects an identification value created earlier, stores the identification value that matches the older timestamp, and transmits it to the first application, thereby identifying all applications installed in the terminal in this way. The values are synchronized identically, and the synchronized identification value is transmitted to the ad server to receive targeted advertisements.

So far, the present invention has been described from the perspective of a software development kit as the main agent. Hereinafter, the present invention will be described from the terminal perspective.

A method of managing a user identification value in a terminal according to an embodiment of the present invention includes the steps of: (a) activating a first application (S410); (b) retrieving the identification value stored in the first application (S420); and (c) requesting an advertisement by transmitting the stored identification value to an advertisement server (S430). The identification value may be stored identically in all applications within the terminal.

The step (a) (S410) is a step in which the application is activated, and the application can be executed according to the user's input. Of course, the application may already be running in the background, but here, activation of the application means a state in which the user can directly view information about the application on the display screen. Meanwhile, the background state refers to a state in which an application is running, but is not directly visible on the display, occupies space in flash memory, and execution of the application is maintained.

In step (b) (S420), the first application can search for an identification value stored in the internal storage (hereinafter referred to as ‘identification value storage unit’ in the present invention). Here, the identification value storage is a storage space inside each application installed on the terminal. Unlike external storage such as an SD card that requires clear permission consent from the user, it is a space unique to each application and does not require separate permissions for access. Therefore, the present invention can enable user-targeting advertisements and re-targeting advertisements by synchronizing the identification value storage units of applications installed in the same terminal so that they all have the same identification value.

Accordingly, in step (c) (S430), when the stored identification value is searched, the stored identification value is transmitted to the advertisement server to request an advertisement. The advertising server recognizes who the user is based on the received identification value and can target advertisements based on cookie data from the site that the user is interested in. Therefore, in the in-app advertising service that serves advertising using an application as a medium, identification of the user or terminal requesting advertising to a specific user is essential.

Therefore, it is important to ensure that all applications installed in the terminal have the same identification value. Therefore, the following describes how identification values are synchronized.

As another example of a method for managing user identification values in a terminal according to the present invention, when there is no identification value stored in the first application, step (b) (S420) includes (b-1) entering a new identification value as a timestamp ( A step of generating by matching timestamp (S440); (b-2) transmitting the new identification value to a second application and querying whether there is an older timestamp (S450); and (b-3) receiving and storing an older identification value determined by the second application (S460).

In step (b-1) (S440), a new identification value can be created by matching a timestamp. This is to determine which one was created first when comparing identification values received from the application later. . Since no application will have an identification value when the terminal is initialized, there is no identification value to compare when the first identification value is created, so the first identification value created ensures that all applications of the terminal have the same identification value. It becomes a standard.

Here, a timestamp is metadata that stores the time or order of when the identification value was created, along with the identification value.

(b-2) In step S450, the new identification value is transmitted to the second application to query whether there is a timestamp older than the new identification value. At this time, the first application refers to an application activated in the terminal, and the second application refers to other applications. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. After receiving this, the second application compares it with the identification value it stored and transmits an identification value that was created a long time ago. The comparison process performed in the second application will be described in detail later with reference to FIG. 5.

(b-3) In step S460, the identification value matching the older timestamp compared in the second application is received and stored. Therefore, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the first application will re-receive and store the identification value generated by itself, and the identification value stored in the second application will be stored. If the identification value is older, the older identification value stored in the second application is received, stored in the first application identification value storage, and transmitted to the advertisement server.

A method for managing user identification values in a terminal according to an embodiment of the present invention, after step (b-2), the second application receives an identification value matched with a timestamp from the first application (S510); Comparing the received identification value with an identification value stored in the second application to select an identification value created earlier (S520); and storing the identification value matched with the older timestamp and transmitting it to the first application (S530).

In step S510, where the second application receives an identification value matching the timestamp from the first application, an identification value newly generated by the first application that does not have a stored identification value is received. The first application refers to an application that is active in the terminal, and the second application refers to another application that has received a query for an identification value from the first application. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

In the step (S520) where the second application compares the identification value received from the first application and the identification value stored in the second application to select an identification value that was created earlier (S520), the time that was generated by matching at the time the identification value was created Through the stamp, it is possible to determine which identification value was created more recently. Accordingly, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the second application retransmits the identification value sent by the first application and transmits the identification value received from the first application. will be stored, and if the identification value stored in the second application is older, the older identification value stored in the second application will be transmitted to the first application, and the first application will transmit the identification value received from the second application. will be saved.

Accordingly, the second application selects the identification value created a long time ago, stores the identification value that matches the older timestamp, and transmits it to the first application (S530), and in this way, all the identification values installed in the terminal are stored. Identification values between applications are equally synchronized, and the synchronized identification values are transmitted to the ad server to receive targeted advertisements.

Meanwhile, the following describes the user identification value management terminal from the device perspective.

In the software development kit (SDK) provided for each application in the terminal, the user identification value management terminal according to an embodiment of the present invention includes an identification value storage unit 110 that stores an identification value; If there is no identification value stored in the identification value storage unit 110, an identification value generator 120 that generates an identification value that specifies the terminal; and an advertisement request unit 130 that requests an advertisement by transmitting the stored identification value to the advertisement server.

The identification value storage unit 110 is a storage space inside each application installed on the terminal. Unlike external storage such as an SD card that requires clear access permission consent from the user, the identification value storage unit 110 is a space unique to each application and requires separate permission for access. don't do it Therefore, the present invention can enable user targeting and re-targeting advertisements by synchronizing the identification value storage unit 110 of applications installed in the same terminal so that they all have the same identification value. there is.

The identification value generation unit 120 may generate a new identification value when there is no identification value stored in the identification value storage unit 110. Since no application will have an identification value when the terminal is initialized, there is no identification value to compare when the first identification value is created, so the first identification value created ensures that all applications of the terminal have the same identification value. It becomes a standard.

At this time, the identification value generator 120 may generate the identification value by matching it with a timestamp. Here, a timestamp is metadata that stores the time or order of when the identification value was created, along with the identification value. Therefore, when comparing the identification values received from the application later, it is possible to determine which one was created first through the timestamp.

If there is a stored identification value, the advertisement request unit 130 transmits the stored identification value to the advertisement server to request an advertisement. The advertising server recognizes who the user is based on the received identification value and can target advertisements based on cookie data from the site that the user is interested in. Therefore, in the in-app advertising service that serves advertising using an application as a medium, identification of the user or terminal requesting advertising to a specific user is essential.

In another embodiment of the present invention, if there is no identification value stored in the identification value storage unit 110, the generated identification value is transmitted to another application, and the identification value selected from the identification value comparison unit 150 of the other application is transmitted. An identification value transmitting and receiving unit 140 that receives and stores the value; And when an identification value is received from another application, an identification value that compares the received identification value with the identification value stored in the identification value storage unit 110 to select an identification value created earlier and retransmits it to the other application. It may further include a comparison unit 150.

When there is no identification value stored in the identification value storage unit 110, the identification value transmitting and receiving unit 140 transmits the new identification value to the second application and queries whether there is a timestamp older than the new identification value. At this time, the first application refers to an application activated in the terminal, and the second application refers to other applications. At this time, the second application may be a plurality of applications and may be any application other than the first application installed on the terminal.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. The identification value comparison unit 150 of the second application compares the identification value stored in the identification storage unit of the second application and transmits an identification value that was created a long time ago.

For example, if the user activates the first application, but there is no identification value stored in the first application, a new identification value is created by matching the timestamp, and a check is made to see if there is an identification value created long before the generated identification value. 1 Query a second application other than the application. After receiving this, the second application compares it with the identification value it stored and transmits an identification value that was created a long time ago.

The identification value comparison unit 150 of the second application receives the identification value matched with the timestamp from the first application, and determines which identification value was created earlier through the timestamp that was matched at the time the identification value was created. You can judge. Accordingly, if there is no identification value generated in the second application, or if the identification value stored in the second application is newer, the second application retransmits the identification value sent by the first application and transmits the identification value received from the first application. will be stored, and if the identification value stored in the second application is older, the older identification value stored in the second application will be transmitted to the first application, and the first application will transmit the identification value received from the second application. will be saved.

Accordingly, the second application selects an identification value created earlier, stores the identification value that matches the older timestamp, and transmits it to the first application, thereby identifying all applications installed in the terminal in this way. The values are synchronized identically, and the synchronized identification value is transmitted to the ad server to receive targeted advertisements.
