Description

METHOD FOR MANAGING USER IDENTITY VALUES IN SOFTWARE DEVELOPMENT KITS AND METHOD FOR MANAGING USER IDENTITY VALUES IN SOFTWARE DEVELOPMENT KITS,

The present invention relates to a method of managing a user identification value in a software development kit and a software development kit thereof, and more particularly, to a method of managing a user identification value in a software development kit, the method comprising: (a) activating a first application; (b) retrieving an identification value stored in the first application; And (c) transmitting the stored identification value to an advertisement server and requesting an advertisement, wherein the identification value is stored in the same manner in all applications in the terminal.

With the development of the communication network and the development of the terminal specification, the communication terminal has become a necessity of the modern person beyond the scope of the conventional simple communication apparatus or information providing apparatus, and has been evolving into a total entertainment apparatus. In addition, communication terminals that can use the Internet provide contents such as advertisement, finance, entertainment, news, and community in various fields.

Especially, most of the means of advertisement delivery through online, which is currently in the limelight, is performed through terminals. Therefore, advertisements made on-line began with a random advertisement on the inventory in the medium. However, as more publishers want to sell advertisements and sell their inventories, advertisers and advertisers are required to relay advertisers' advertisements to the publisher's inventory. We started with a way of exposing, and now we have developed targeted advertising technology in the form of exposing selected ads based on user visit information.

Here, the medium in which the advertisement is exposed to the user is called a medium, and the space in the medium where the advertisement is exposed is called an inventory. If the medium is an application, it is called in-application (in-app). If the medium is a web site, it is called mobile web (m-web). In addition, a method of selecting an advertisement that is likely to have a high degree of interest based on user's unique information is called targeting.

On the other hand, as shown in FIG. 1, in an in-app advertisement service that serves advertisements using an application medium, it is necessary to identify the user or the terminal requesting the advertisement in order to send an advertisement targeted to a specific user.

Conventionally, as a method for identifying a user or a terminal, a telephone number of a user, a unique identification value of a device, a unique identification value of a platform, and the like have been used as shown in FIG. 2. However, And has been restrained under a legal / platform policy. That is, the inherent value generated in the process of producing the device or the inherent value that can represent the individual can not be used.

In order to avoid such a problem, there is a method of continuously generating and managing arbitrary values without using a unique value of a device or an individual, and such values are meaningful to be commonly used in various applications installed in the same terminal. That is, the fact that various applications installed in the same terminal have different identification values is meaningless in the case of targeting advertisement. Therefore, as shown in FIG. 3, a method of sharing such identification values in various applications via an external storage such as an SD card has been conventionally used. However, recently, the enhanced platform policy restricts access to external storage such as an SD card And it became difficult to use conventional technology anymore.

The present invention has been invented based on such a technical background and has been invented to provide additional technical elements which can not easily be invented by a person having ordinary skill in the art, as well as satisfying the technical requirements of the present invention.

Before describing the present invention, the concept and terminology of targeting, retargeting in the field of the present invention will be described.

The first form of online advertising is that advertisers and publishers directly deal with advertisements and inventory without an ad agency. However, as the number of Internet users increases, the effect of Internet advertising increases rapidly. As a result, There are a lot of publishers who want to sell their inventory. As a result, an advertising agency server for advertising and inventory transactions between advertisers and publishers appeared. This method is a method in which random advertisement is exposed to the inventory in the medium. Then, based on the visit information of the user, the user is identified according to the user's access and the advertisement is selectively selected based on the user's information, Advertising was developed.

Retargeting ads are a type of advertising that attracts interested users with high conversion rates through marketing activities, such as search ads, and then exposes the images of products of particular interest to interested visitors through retargeting media. Advertising. This is not a form of pop-up or manually visible advertisement when a user visits the website, but rather an advertiser who sells the advertisement and purchases the advertisement to be displayed, a DSP (Demand Side Platform) server that finds an appropriate inventory to display the advertisement on behalf of the advertiser , The publisher who sells the advertisement to be displayed, and the SSP (Supply Side Platform) server which finds the advertisement to be exposed on behalf of the publisher, and identifies the advertisement target user according to the user age, And sends the advertisement to the user terminal.

At this time, the DSP server generates retargeting advertisements for the targeting information on a user-by-user basis by analyzing data on the information of browsing a specific page in the website visited by the user, the shopping cart history of the visited user, login information, Thereafter, the classified advertisement characteristics are classified according to the targeting information, and when the user detects that the user accesses the site of the publisher, the classified advertisement service is provided in such a manner that the classified advertisement is transmitted according to the targeting information of the user.

The terms used in the present invention are defined as follows.

Retargeting Ads is a product that has experience of visiting an advertiser's website or has experienced viewing a specific page within the website, Or a method of showing an advertisement for a service again.

In this case, the targeting information means information used by a user who visited the advertiser's web site to select an advertisement considering an action taken in the advertiser's web site. Therefore, information that a specific page is browsed within the website visited by the user or a shopping cart history of the user who visited, login information, and the like can be the targeting information.

Media refers to media through which advertisements are exposed to users. For example, TV, radio, and the Internet are the means by which advertisements can be exposed. The present invention is directed to a retargeting advertisement on-line, and the Internet can be a medium.

Inventory means the space in the medium where the advertisement is exposed. In the case of the Internet, inventory can be a specific space for placing advertisements on a website.

An advertiser is someone who wants to buy inventory that will show ads to show their ads.

A publisher is a person who has an inventory in the medium where the advertisement can be placed.

A demand side platform (DSP) server is a server that is managed by a vendor looking for an appropriate inventory to advertise on behalf of an advertiser.

A supply side platform (SSP) server is a server managed by a vendor who sells inventory on behalf of publishers and seeks ads to be exposed.

If the medium is an application, it is called in-application (in-app). If the medium is a web site, it is called mobile web (m-web). In addition, a method of selecting an advertisement that is likely to have a high degree of interest based on user's unique information is called targeting.

Meanwhile, in an in-app advertisement service that serves advertisements using an application medium, in order to transmit an advertisement targeted to a specific user, identification of the user or terminal requesting the advertisement is necessarily required.

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

2, in order to identify a user or a terminal, a user's phone number, a unique identification value of a device, a unique identification value of a platform, and the like have been used. However, Policy has been restrained. That is, the inherent value generated in the process of producing the device or the inherent value that can represent the individual can not be used.

In order to avoid such a problem, there is a method of continuously generating and managing arbitrary values without using a unique value of a device or an individual, but such values are meaningful to be commonly used in various applications installed in the same terminal. Therefore, it is meaningless that various applications installed in the same terminal have different identification values.

3 is a view for explaining a method in which a plurality of applications share an identification value through an external storage such as an SD card.

Referring to FIG. 3, a method of sharing such identification values in various applications through an external storage such as an SD card is used. However, recently, the enhanced platform policy has restricted access to the external storage such as the SD card, and the method shown in FIG. 2 is also difficult to use any more.

Accordingly, the present invention proposes a scheme for allowing all applications installed in the same terminal to have the same identification value, so as to enable a user targeting advertisement and a re-targeting advertisement.

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

Referring to FIG. 4, each application stores an advertisement identification value in its identification value storage unit. Then, the advertisement identification values are synchronized so that they have the same value in each application, so that the identification values existing in each application in the same terminal have the same value.

The identification value required for the user-targeted advertisement request is different from the identification value stored in the identification value storage unit of each application.

Here, the identification value storage unit is a storage space within each application installed in the terminal, and unlike the external storage requiring clear access right of the user, a separate authority for access is not required as a unique space of the individual application. Therefore, the present invention can synchronize the identification value storage of the application installed in the same terminal so that all the same identification value can be used to enable user targeting advertisement and re-targeting advertisement.

On the other hand, the method of synchronizing the identification value between applications can utilize the IPC mechanism provided by the operating system or the platform. For example, you can use the Broadcast Receiver feature on the Android platform. The Broadcast Receiver system provides the ability to simultaneously broadcast commands and some parameters to applications that declare receipt of events for a specific command.

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

A software development kit is a collection of development tools that allow software engineers to create applications for specific software packages, software frameworks, hardware platforms, computer systems, game machines, operating systems, and so on.

In terms of any file to include complex hardware that connects to a particular programming language or communicates with a particular embedded system, it can simply be written 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 clear points to users by supporting technical references or supporting documentation, including sample code.

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

In the step (a) (S410), the application may be executed according to the input of the user at the step of activating the application. Of course, the application may already be executed in the background, but the activation of the application means that the user can directly view the information of the application on the display screen. On the other hand, the background state means a state in which the application is executed but occupies a space in the flash memory in a state where it is not seen that the application is directly executed, and the 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' in the present invention). Here, the identification value storage unit is a storage space inside each application installed in the terminal, and unlike an external storage such as an SD card requiring explicit permission of access by the user, a separate authority for access is not required as a unique space of an individual application. Therefore, the present invention can synchronize the identification value storage of the application installed in the same terminal so that all the same identification value can be used to enable user targeting advertisement and re-targeting advertisement.

In step (c) (S430), when the stored identification value is searched, the stored identification value is transmitted to the advertisement server to request the advertisement. The advertisement server recognizes the user based on the received identification value, and can perform targeted advertisement based on the cookie data of the site with interest by the user. Therefore, in an in-app advertisement service that serves advertisements using an application as a medium, it is necessary to identify a user or a terminal requesting an advertisement to a specific user.

Therefore, it is important that all applications installed in the terminal have the same identification value. Therefore, a method of synchronizing identification values will be described below.

(B-1) if the identification value stored in the first application does not exist, the step (b-1) updates the new identification value to a time A step (S440) of generating by matching with a stamp (timestamp); (b-2) transmitting the new identification value to the second application and querying for an older timestamp (S450); And (b-3) receiving and storing an older identification value determined by the second application (S460).

In step (b-1), a new identification value may be generated by matching with a time stamp (timestamp) in order to determine which one was generated first when comparing the identification values received in the application thereafter . When the terminal is initialized, no application will have an identification value. Therefore, when the first identification value is created, there is no identification value to be compared. Therefore, the first identification value is set such that all applications of the terminal have the same identification value Standard.

Here, the time stamp is metadata in which the time or order in which the identification value is generated is stored together with the identification value.

(b-2) In step S450, the new identification value is transmitted to the second application to inquire whether there is an older time stamp than the new identification value. Here, the first application means an application activated in the terminal, and the second application means other applications. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to a second application other than the application. The second application receives the ID and compares it with the ID stored in the second application, and transmits the ID generated earlier. The comparison process performed in the second application will be described in detail with reference to FIG.

(b-3) In step (S460), an oldest timestamp and an identification value matched in the second application are 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 identification value generated by the first application itself will be received again and stored, and stored in the second application If the identified identification value is older, the older identification value stored in the second application is received and stored in the first application identification value storage unit and transmitted to the advertisement server.

FIG. 6 illustrates a method of managing a user identification value in a software development kit according to an exemplary embodiment of the present invention. Referring to FIG. 6, a method for comparing an identification value of a second application that receives a query from a first application will be described.

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

In step S510, the second application receives the identification value matched with the time stamp from the first application, and receives the newly generated identification value from the first application having no stored identification value. The first application means an application being activated in the terminal, and the second application means an application which is inquired of the identification value from the first application by another application. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

In the step S520 of comparing the identification value received from the first application by the second application with the identification value stored in the second application and sorting the generated identification value a long time ago, The stamp can be used to determine which identification value was generated a long time ago. 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 transmitted by the first application, If the identification value stored in the second application is older than the first identification information, the first application transmits an older identification value stored in the second application to the first application, Will be stored.

The second application selects the identification value generated a long time ago, stores the identification value matched with the older time stamp, and transmits the identification value to the first application (S530). In this manner, The identification values of the applications are synchronized in the same manner, and the synchronized identification value is transmitted to the advertisement server to receive the targeted advertisement.

In the following, we will describe the user identification value management software development kit from the perspective of the device.

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

Referring to FIG. 7, in a software development kit (SDK) provided in each application in a terminal, a user identification value management software development kit according to an embodiment of the present invention includes an identification Value storing unit 110; An identification value generation unit (120) for generating an identification value for identifying a terminal when there is no identification value stored in the identification value storage unit (110); And an advertisement requesting unit 130 for sending the stored identification value to the advertisement server to request an advertisement.

The identification value storage unit 110 is a storage space inside each application installed in the terminal, and unlike an external storage such as an SD card, which requires explicit permission of a user to access the application, I do not. Therefore, the present invention can synchronize the identification value storage unit 110 of an application installed in the same terminal, and can have both the same identification value to enable a user targeting advertisement and a re-targeting advertisement have.

The identification value generation unit 120 may generate a new identification value if the identification value stored in the identification value storage unit 110 does not exist. When the terminal is initialized, no application will have an identification value. Therefore, when the first identification value is created, there is no identification value to be compared. Therefore, the first identification value is set such that all applications of the terminal have the same identification value Standard.

In this case, the identification value generator 120 may generate the identification value by matching the identification value with a time stamp. Here, the time stamp is metadata in which the time or order in which the identification value is generated is stored together with the identification value. Therefore, when comparing the identification values received by the application in the future, it is possible to determine the next through the time stamp of which one was generated first.

If there is a stored identification value, the advertisement requesting unit 130 transmits the stored identification value to the advertisement server to request an advertisement. The advertisement server recognizes the user based on the received identification value, and can perform targeted advertisement based on the cookie data of the site with interest by the user. Therefore, in an in-app advertisement service that serves advertisements using an application as a medium, it is necessary to identify a user or a terminal requesting an advertisement to a specific user.

In another embodiment of the present invention, when 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 comparison unit 150 of the other application An identification value transmission / reception unit 140 for receiving and storing a value; And an identification value stored in the identification value storing unit 110 to compare the received identification value with the identification value stored in the identification value storing unit 110. The identification value generated earlier is selected and the identification value And a comparison unit 150. [0034] FIG.

When there is no identification value stored in the identification value storage unit 110, the identification value transmission / reception unit 140 transmits the new identification value to the second application and inquires whether there is an older time stamp than the new identification value. Here, the first application means an application activated in the terminal, and the second application means other applications. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to 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 unit storage unit of the second application and transmits the identification value generated long ago.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to a second application other than the application. The second application receives the ID and compares it with the ID stored in the second application, and transmits the ID generated earlier.

The identification value comparison unit 150 of the second application receives the identification value matched with the time stamp from the first application and identifies which identification value was generated a long time ago through the time stamp which was generated by matching when the identification value was generated It can be judged. 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 transmitted by the first application, If the identification value stored in the second application is older than the first identification information, the first application transmits an older identification value stored in the second application to the first application, Will be stored.

The second application selects the identification value generated a long time ago, stores the identification value matched with the older time stamp, and transmits the identification value to the first application. In this manner, And the synchronized identification value is transmitted to the advertisement server to receive the targeted advertisement.

Up to now, the present invention has been described in terms of a software development kit. Hereinafter, the present invention will be described in terms of a terminal.

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

In the step (a) (S410), the application may be executed according to the input of the user at the step of activating the application. Of course, the application may already be executed in the background, but the activation of the application means that the user can directly view the information of the application on the display screen. On the other hand, the background state means a state in which the application is executed but occupies a space in the flash memory in a state where it is not seen that the application is directly executed, and the 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' in the present invention). Here, the identification value storage unit is a storage space inside each application installed in the terminal, and unlike an external storage such as an SD card requiring explicit permission of access by the user, a separate authority for access is not required as a unique space of an individual application. Therefore, the present invention can synchronize the identification value storage of the application installed in the same terminal so that all the same identification value can be used to enable user targeting advertisement and re-targeting advertisement.

In step (c) (S430), when the stored identification value is searched, the stored identification value is transmitted to the advertisement server to request the advertisement. The advertisement server recognizes the user based on the received identification value, and can perform targeted advertisement based on the cookie data of the site with interest by the user. Therefore, in an in-app advertisement service that serves advertisements using an application as a medium, it is necessary to identify a user or a terminal requesting an advertisement to a specific user.

Therefore, it is important that all applications installed in the terminal have the same identification value. Therefore, a method of synchronizing identification values will be described below.

(B) step (S420), when the identification value stored in the first application does not exist, (b-1) a new identification value with a time stamp (step S440); (b-2) transmitting the new identification value to the second application and querying for an older timestamp (S450); And (b-3) receiving and storing an older identification value determined by the second application (S460).

In step (b-1), a new identification value may be generated by matching with a time stamp (timestamp) in order to determine which one was generated first when comparing the identification values received in the application thereafter . When the terminal is initialized, no application will have an identification value. Therefore, when the first identification value is created, there is no identification value to be compared. Therefore, the first identification value is set such that all applications of the terminal have the same identification value Standard.

Here, the time stamp is metadata in which the time or order in which the identification value is generated is stored together with the identification value.

(b-2) In step S450, the new identification value is transmitted to the second application to inquire whether there is an older time stamp than the new identification value. Here, the first application means an application activated in the terminal, and the second application means other applications. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to a second application other than the application. The second application receives the ID and compares it with the ID stored in the second application, and transmits the ID generated earlier. The comparison process performed in the second application will be described in detail with reference to FIG.

(b-3) In step (S460), an oldest timestamp and an identification value matched in the second application are 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 identification value generated by the first application itself will be received again and stored, and stored in the second application If the identified identification value is older, the older identification value stored in the second application is received and stored in the first application identification value storage unit and transmitted to the advertisement server.

A method for managing a user identification value in a terminal according to an embodiment of the present invention includes: receiving (S510) an identification value matched with a time stamp from a first application after a step (b-2); Comparing the received identification value with an identification value stored in the second application to select a previously generated identification value (S520); And storing the identification value matched with the older timestamp and transmitting the identification value to the first application (S530).

In step S510, the second application receives the identification value matched with the time stamp from the first application, and receives the newly generated identification value from the first application having no stored identification value. The first application means an application being activated in the terminal, and the second application means an application which is inquired of the identification value from the first application by another application. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

In the step S520 of comparing the identification value received from the first application by the second application with the identification value stored in the second application and sorting the generated identification value a long time ago, The stamp can be used to determine which identification value was generated a long time ago. 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 transmitted by the first application, If the identification value stored in the second application is older than the first identification information, the first application transmits an older identification value stored in the second application to the first application, Will be stored.

The second application selects the identification value generated a long time ago, stores the identification value matched with the older time stamp, and transmits the identification value to the first application (S530). In this manner, The identification values of the applications are synchronized in the same manner, and the synchronized identification value is transmitted to the advertisement server to receive the targeted advertisement.

In the following, a user identification value management terminal will be described from the viewpoint of the apparatus.

In a software development kit (SDK) provided in each application in a terminal, a user identification value management terminal according to an embodiment of the present invention includes an identification value storage unit 110 for storing identification values; An identification value generation unit (120) for generating an identification value for identifying a terminal when there is no identification value stored in the identification value storage unit (110); And an advertisement requesting unit 130 for sending the stored identification value to the advertisement server to request an advertisement.

The identification value storage unit 110 is a storage space inside each application installed in the terminal, and unlike an external storage such as an SD card, which requires explicit permission of a user to access the application, I do not. Therefore, the present invention can synchronize the identification value storage unit 110 of an application installed in the same terminal, and can have both the same identification value to enable a user targeting advertisement and a re-targeting advertisement have.

The identification value generation unit 120 may generate a new identification value if the identification value stored in the identification value storage unit 110 does not exist. When the terminal is initialized, no application will have an identification value. Therefore, when the first identification value is created, there is no identification value to be compared. Therefore, the first identification value is set such that all applications of the terminal have the same identification value Standard.

In this case, the identification value generator 120 may generate the identification value by matching the identification value with a time stamp. Here, the time stamp is metadata in which the time or order in which the identification value is generated is stored together with the identification value. Therefore, when comparing the identification values received by the application in the future, it is possible to determine the next through the time stamp of which one was generated first.

If there is a stored identification value, the advertisement requesting unit 130 transmits the stored identification value to the advertisement server to request an advertisement. The advertisement server recognizes the user based on the received identification value, and can perform targeted advertisement based on the cookie data of the site with interest by the user. Therefore, in an in-app advertisement service that serves advertisements using an application as a medium, it is necessary to identify a user or a terminal requesting an advertisement to a specific user.

In another embodiment of the present invention, when 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 comparison unit 150 of the other application An identification value transmission / reception unit 140 for receiving and storing a value; And an identification value stored in the identification value storing unit 110 to compare the received identification value with the identification value stored in the identification value storing unit 110. The identification value generated earlier is selected and the identification value And a comparison unit 150. [0034] FIG.

When there is no identification value stored in the identification value storage unit 110, the identification value transmission / reception unit 140 transmits the new identification value to the second application and inquires whether there is an older time stamp than the new identification value. Here, the first application means an application activated in the terminal, and the second application means other applications. In this case, the second application may be a plurality of applications, and may be all applications other than the first application installed in the terminal.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to 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 unit storage unit of the second application and transmits the identification value generated long ago.

For example, if the user activates the first application and there is no identification value stored in the first application, the identification value is newly generated by matching with the time stamp, and if the identification value generated before the generated identification value exists 1 application to a second application other than the application. The second application receives the ID and compares it with the ID stored in the second application, and transmits the ID generated earlier.

The identification value comparison unit 150 of the second application receives the identification value matched with the time stamp from the first application and identifies which identification value was generated a long time ago through the time stamp which was generated by matching when the identification value was generated It can be judged. 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 transmitted by the first application, If the identification value stored in the second application is older than the first identification information, the first application transmits an older identification value stored in the second application to the first application, Will be stored.

The second application selects the identification value generated a long time ago, stores the identification value matched with the older time stamp, and transmits the identification value to the first application. In this manner, And the synchronized identification value is transmitted to the advertisement server to receive the targeted advertisement.
