[1. Access processing including transfer processing]
Access processing according to the embodiment will be described with reference to FIG. FIG. 1 is an explanatory diagram of the access processing according to the embodiment, and the access processing is executed by an access processing system 1 in the present embodiment.

As shown in FIG. 1 , the access processing system 1 has a terminal device 10 , a first domain server 100 and a second domain server 200 .

The terminal device 10 is, for example, a smart device such as a smart phone or a tablet terminal, and is an information processing device used by a user. The terminal device 10 is installed with an application and a browser for browsing web pages, SNSs, etc., and according to the user's operation, the application and the browser installed in the terminal device 10 are activated, and various processes are performed. I let you. The terminal device 10 described above is, for example, a desktop/laptop PC (personal computer), a mobile phone (feature phone), a stationary/portable game machine, an AV (audio visual) device, an information appliance, or other Internet It may be an electronic device or the like through which information can be provided.

The first domain server 100 is a server device that can be accessed in the first domain, and is a content server that distributes web pages, SNS, and the like that can be browsed by the user using the terminal device 10 . For example, when the first domain server 100 receives a URL (Uniform Resource Locator) of a web page including the first domain from the terminal device 10 , it transmits data of the web page indicated by the received URL to the terminal device 10 . Note that the URL is an example of a Uniform Resource Identifier (URI).

The second domain server 200 is a server device that can be accessed in a second domain different from the first domain. It is a management server that issues and manages identification information "yclid" and related information.

The terminal device 10, the first domain server 100, and the second domain server 200 are communicably connected by wire or wirelessly via a network N such as the Internet. Note that each of the first domain server 100 and the second domain server 200 may be a cloud server using cloud computing on the network N. Also, a plurality of first domain servers 100 may exist. In this case, each first domain of the plurality of first domain servers 100 is assumed to be a different domain. That is, each first domain is independent.

As shown in FIG. 1, the first domain server 100 distributes first content belonging to the first domain over the network N (step S1). The first content is, for example, a web page, SNS, or the like.

The terminal device 10 accesses the first content belonging to the first domain distributed by the first domain server 100 and displays the first content (step S2). The user operates the terminal device 10 to select the link to the third content included in the first content belonging to the first domain (step S3). A link to the third content is a link included in a web page or the like, such as an Internet advertisement or the like. Internet advertisements include, for example, banner advertisements/listing advertisements/video advertisements/SNS advertisements/in-feed advertisements. The third content is, for example, a web page or the like that introduces/provides (sells, etc.) products, services, etc. posted in Internet advertisements.

A web page is composed of, for example, HTML (HyperText Markup Language), style sheets (CSS: Cascading Style Sheets), image data, etc., and links are set by tags or the like. A link to the third content is an address (URL, etc.) within the first domain. For example, in the script embedded in the web page, "When the linked content (character string or image) is clicked, move to the address of the second content belonging to the second domain, and then It contains the command "return to the address of the third content belonging to the first domain".

Before the linked third content is received by the terminal device 10, a request for access to the third content by the terminal device 10 is redirected to the second domain server 200 as a request for access to the second content belonging to the second domain. (transferred) (step S4). The second content is, for example, a site for issuing identification information “yclid” to the user of the terminal device 10 . Also, the second domain server 200 may be a transfer device (redirector).

In this embodiment, redirection is executed only when a link that transitions to the same domain within the client site (here, a link that transitions from the first content belonging to the first domain to the third content) is clicked. Links within the same page and links to other domains are not supported. Also, if the identification information "yclid" is already stored in the first party cookie, it will not be redirected. Therefore, redirects do not occur at every page transition within the client site. This time, the redirect occurs because the identification information "yclid" has not yet been stored in the first party cookie.

The second domain server 200 issues identification information "yclid" to the user of the terminal device 10 in response to the redirection to the second content belonging to the second domain (step S5). At this time, the second domain server 200 is notified of the URL (redirect destination) of the third content together with the access request to the second content from the terminal device 10 . After issuing the identification information "yclid", the second domain server 200 sends the identification information "yclid" to the terminal device 10 as well as the third content belonging to the first domain, which is the original link destination, as the redirect destination. address.

The terminal device 10 acquires the identification information "yclid" from the second domain server 200 (step S6). At this time, the terminal device 10 stores the identification information "yclid" in the first-party cookie of the first domain. For example, the script embedded in the web page of the linked third content includes an instruction "use the identification information to generate a first party cookie".

The terminal device 10 requests the third content belonging to the first domain from the first domain server 100 (step S7). For example, the terminal device 10 transmits an access request including the address of the third content to the first domain server 100 .

Also, the first domain server 100 distributes the third content belonging to the first domain to the terminal device 10 (step S8).

The terminal device 10 displays the third content belonging to the first domain distributed by the first domain server 100 (step S9).

Further, the terminal device 10 notifies the second domain server 200 of the identification information "yclid" and the viewing information (step S10). For example, the script embedded in the web page of the linked third content includes an instruction to "send identification information and browsing information to the second domain." The browsing information is, for example, information about retargeting tags.

The second domain server 200 associates the identification information "yclid" received from each of the plurality of first domain servers 100 with different domains with the browsing information, respectively, and manages them as a browsing history, and from the browsing history of each domain, A distribution target is selected (step S11). A distribution target is, for example, a retargeting advertisement. After that, the second domain server 200 notifies the terminal device 10 of the selected distribution target (step S12). That is, the user receives the distribution target via the terminal device 10 .

[7. effect〕
The registration program, which is the registration application 43 according to the embodiment, causes the computer 300 corresponding to the terminal device 10 according to the embodiment to execute an acquisition procedure 432 and a registration procedure 433 . In the obtaining procedure 432, when the user selects the link set to the first content belonging to the first domain, the second domain is obtained via the second content belonging to the second domain different from the first domain. Acquire the identification information for identifying the user generated in . The registration procedure 433 registers the identification information for identifying the user generated in the second domain as identification information for identifying the user with respect to the first domain. Thereby, the identification information for identifying the user can be acquired and registered without the user being aware of it. As a result, a first-party cookie using the identification information can be generated, and appropriate information can be provided to the user even when the use of third-party cookies is restricted.

The registration procedure 433 registers the identification information with the terminal device 10 that receives the content belonging to the first domain. Specifically, the registration procedure 433 creates a first-domain first-party cookie in the terminal device 10 that includes the identification information. Thereby, the identification information for identifying the user can be registered not on the side of the Web server that distributes the content but on the side of the terminal device 10 that receives the content.

The acquisition procedure 432 is a link set to the first content belonging to the first domain, and when the user selects a link to the third content belonging to the first domain, the second content to obtain the identification information. Thereby, when the link to the third content set in the first content is selected, it is possible to redirect to the second content and acquire the identification information.

When the link is selected, the obtaining procedure 432 obtains the second content, and in the state where the second content is obtained, generates the user generated in the second domain. Get identity information. Thereby, the second content and the identification information can be acquired at the same time.

The acquisition procedure 432 acquires the third content when the identification information is acquired. Thereby, the identification information can be acquired before acquiring the third content.

The obtaining procedure 432 obtains, as the identification information, information obtained by converting the information indicating the first domain and the information indicating the user using a predetermined function. Accordingly, since the identification information is generated based on the set of the information indicating the first domain and the information indicating the user, the identification information can be embodied.

The registration procedure 433 registers the identification information as information that associates the identification information with behavior information indicating behavior of the user in the first domain. The behavior information is, for example, browsing history. Thereby, it is possible to grasp the behavior of the user based on the identification information.

The registration program, which is the registration application 43 according to the embodiment, further causes the computer 300 corresponding to the terminal device 10 to execute the providing procedure 434 . The provision procedure 434 provides the identification information registered by the registration procedure 433 and the behavior information associated with the identification information to the second domain server 200, which is an information processing device belonging to the second domain. . As a result, a set of identification information and action information can be transmitted to the information processing device of the second domain.

The provision procedure 434 is an information processing device that provides information (delivery target) selected according to the behavior information to the user identified by the identification information associated with the behavior information. is provided to the second domain server 200. As a result, it is possible to provide a distribution target such as a retargeting advertisement selected according to behavior information to a user having identification information associated with the behavior information.

Acquire the identification information for identifying the generated user. The registration unit registers identification information for identifying the user generated in the second domain as identification information for identifying the user with respect to the first domain. Thereby, the identification information for identifying the user can be acquired and registered without the user being aware of it. As a result, a first-party cookie using the identification information can be generated, and appropriate information can be provided to the user even when the use of third-party cookies is restricted.

The registration method executed by the registration device, which is the terminal device 10 according to the embodiment, includes an acquisition process and a registration process. In the acquisition step, when the user selects a link set to a first content belonging to a first domain, the second content belongs to a second domain different from the first domain, and the second content belongs to the second domain. Acquire the identification information for identifying the generated user. The registration step registers identification information for identifying the user generated in the second domain as identification information for identifying the user with respect to the first domain. Thereby, the identification information for identifying the user can be acquired and registered without the user being aware of it. As a result, a first-party cookie using the identification information can be generated, and appropriate information can be provided to the user even when the use of third-party cookies is restricted.

The provision device, which is the second domain server 200 according to the embodiment, has a generation unit 232 and a provision unit 233 . The generating unit 232 receives a distribution request for second content belonging to a second domain different from the first domain and a third content belonging to the first domain from the terminal device 10 displaying the first content belonging to the first domain. is received, identification information for identifying the user is generated in the second domain. The providing unit provides the generated identification information to the terminal device 10 and provides the unified resource identifier of the third content as a redirect destination. Accordingly, identification information and a redirect destination can be provided to the user of the terminal device while generating the identification information.

The providing method executed by the providing device, which is the second domain server 200 according to the embodiment, includes a generating process and a providing process. In the generation step, a distribution request for second content belonging to a second domain different from the first domain and a delivery request for third content belonging to the first domain are sent from the terminal device 10 displaying the first content belonging to the first domain. When the uniform resource identifier is accepted, identification information for identifying the user is generated in the second domain. The provision step provides the generated identification information to the terminal device 10 and provides the unified resource identifier of the third content as a redirect destination. Accordingly, identification information and a redirect destination can be provided to the user of the terminal device while generating the identification information.
