  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention. In the drawings, the same or similar parts are denoted by the same reference numerals, and redundant description may be omitted.

[Outline of Distribution System 100]
FIG. 1 schematically shows an example of the system configuration of the distribution system 100. In the present embodiment, the distribution system 100 includes a client terminal 102, a Web server 104, an SSP server 110, a DSP server 120, a DMP server 132, an advertisement server 134, and a permanent ID storage unit 140. For example, the permanent ID storage unit 140 includes a Web server 142 and an MNO server 144.

  The distribution system 100, the Web server 104, the SSP server 110, and the DSP server 120 may be an example of an advertisement distribution system. The permanent ID storage unit 140, the Web server 142, and the MNO server 144 may be an example of an identifier synchronization system. The SSP server 110 and the DSP server 120 may be an example of a first information processing apparatus. The permanent ID storage unit 140, the Web server 142, and the MNO server 144 may be an example of a second information processing apparatus.

  In the present embodiment, the distribution system 100 distributes advertisement information to the client terminal 102 via the communication network 10. For example, when the content distributed from the Web server 104 to the client terminal 102 includes an advertisement display area, the distribution system 100 determines advertisement information to be displayed in the advertisement display area, and the advertisement information (referred to as an advertisement creative). Is distributed to the client terminal 102.

  The content may be digital data, and the type and content of the content are not particularly limited. The content may be character data, music data, still image data, or moving image data.

  The advertisement information may be information notified to the user of the client terminal 102, and the content of the advertisement is not particularly limited. The advertisement information may be information related to a product or service of an advertisement provider (sometimes referred to as an advertiser). The information on the product or service may be discount information on the product or service (sometimes referred to as coupon information), event notification information, or the like.

  As another example of information on goods or services, when the advertisement provider is public transportation, the advertisement information may be suspension information, delay information, traffic jam information, and the like. In addition, when the advertisement provider is a business provider or a government agency that provides a weather forecast service, the advertisement information may be a warning or warning regarding local heavy rain, lightning strikes, gusts, and the like. The advertisement information may be information regarding a disaster. The advertisement information may be information regarding a specific area.

  In the field of online advertising, advertising distribution technologies such as RTB (Real time Bidding) via SSP (Supply-Side Platform) and DSP (Demand-Side Platform) are used. According to such an advertisement distribution technique, it is possible to distribute a more useful advertisement to the user of the client terminal 102 by using a cookie of a browser operating on the client terminal 102. By using the information stored in the cookie of the client terminal 102, for example, the client terminal 102 is tracked to collect user audience data, or the user information is acquired by accessing the DMP (Data Management Platform). Can be.

  However, SSP, DSP, and DMP are basically Third Parties, and rarely communicate with the client terminal 102 as a First Party. Therefore, when reading and writing of Third Party Cookie (sometimes referred to as a third party cookie) is prohibited by the browser of the client terminal 102, the SSP and the DSP may collect detailed information regarding the user of the client terminal 102. It becomes impossible to distribute a useful advertisement to the user.

  Therefore, according to an example of this embodiment, the SSP server 110 or the DSP server 120 sends its own cookie information from the client terminal 102 because the browser of the client terminal 102 does not permit reading / writing of third party cookies. If it cannot be obtained, the DSP server 120 issues a unique ID issued to the client terminal 102 by the SSP server 110 or the DSP server 120 as the Third Party and other identification information assigned to the client terminal 102 ( Information indicating a correspondence relationship with the identifier is sometimes acquired. The other identification information may be any information that can be used for tracking of the client terminal 102 as in the case of the cookie information, and the type thereof is not particularly limited. Thereby, the DSP server 120 can deliver a more useful advertisement to the user of the client terminal 102. In addition, advertising revenue can be increased.

  According to another example, the SSP server 110 acquires other identification information assigned to the client terminal 102 before sending a bid request to the DSP server 120. The SSP server 110 transmits a bid request including other identification information or the encrypted data or the encoded data (for example, a hash value) to the DSP server 120. Thereby, the DSP server 120 can deliver a more useful advertisement to the user of the client terminal 102. In addition, advertising revenue can be increased.

  In S206, the DSP server 120 refers to the bid history stored in the DSP server 120 using the cookie ID included in the bid request as a key, and acquires the attribute information of the user of the client terminal 102. The DSP server 120 may acquire attribute information of the user of the client terminal 102 by referring to the DMP server 132 using the cookie ID included in the bid request as a key. The DSP server 120 extracts advertisement information to be displayed in the advertisement space 22 from the plurality of advertisement information stored in the advertisement server 134 based on the user attribute information. Further, the DSP server 120 determines a bid price and transmits a bid response including information indicating the bid price to the SSP server 110.

  In S207, the SSP server 110 executes an auction and determines a winner DSP based on one or more bid responses transmitted from the one or more DSP servers 120. The SSP server 110 transmits the advertisement tag of the winner DSP to the client terminal 102.

  In S <b> 208, the browser of the client terminal 102 transmits an advertisement request to the DSP server 120 using the advertisement tag transmitted from the SSP server 110. In step S <b> 209, the DSP server 120 transmits advertisement information to the client terminal 102. The browser of the client terminal 102 displays content including advertisement information on the display of the client terminal 102. As described above, when the browser of the client terminal 102 permits reading / writing of a third party cookie, the advertisement useful for the user is distributed using the cookie information regarding the domain of the SSP server 110. can do.

  FIG. 3 schematically shows an example of information processing in the distribution system 100. 3, when the browser of the client terminal 102 does not permit reading / writing of a third party cookie, the unique ID issued by the SSP server 110 or the unique ID issued by the DSP server 120 and other permanent IDs An example of an embodiment in which the synchronization information that links the two is created and the advertisement is distributed will be described. In the present embodiment, the browser of the client terminal 102 is set to permit reading and writing of cookie information (sometimes referred to as Visited Third Party Cookie) related to a domain accessed in the past as a First Party. . In the present embodiment, the Web server 142 acquires information indicating the address of the DSP server 120 in advance.

  In the present embodiment, first, in session A, the client terminal 102 accesses the Web server 142. Thereafter, the client terminal 102 accesses the Web server 104 in a session B different from the session A. Regarding the session A, the browser of the client terminal 102 accesses the Web server 142 in S30. In S32, the Web server 142 writes a cookie ID (sometimes abbreviated as C_fp) for the Web server 142 to identify the client terminal 102 in the cookie area of the browser of the client terminal 102. Since the Web server 142 is a First Party, the above writing is permitted. C_fp may be an example of a first user identifier and a user identifier.

  Regarding session B, first, in S 300, the browser of the client terminal 102 accesses the Web server 104 and transmits a content distribution request to the Web server 104. For example, the content distribution request requests data of the Web page 20.

  In S <b> 302, the Web server 104 transmits the data of the Web page 20 to the client terminal 102. At this time, if the cookie ID for identifying the client terminal 102 by the Web server 104 (may be abbreviated as C_pub) is not stored in the cookie area of the browser of the client terminal 102, the Web server 104 Write C_pub in the cookie area. C_pub may be an example of a first user identifier and a user identifier.

  In S310, when the browser of the client terminal 102 executes the Web page 20, an impression of the advertising space 22 is generated. The browser of the client terminal 102 transmits an advertisement request to the SSP server 110. At this time, since the SSP server 110 is a Third Party, the header of the advertisement request does not include cookie information regarding the domain of the SSP server 110.

  In S <b> 312, the SSP server 110 issues a temporary cookie ID (sometimes abbreviated as C_ssp_t) for the SSP server 110 to identify the client terminal 102. The SSP server 110 transmits C_ssp_t to the client terminal 102. The browser of the client terminal 102 reserves a browser area for the SSP server 110. The reserved browser area is, for example, an area surrounded by <iframe src = “”> and </ iframe>. In S312, the SSP server 110 transmits a program corresponding to the browser area. The program corresponding to the browser area may be a program for generating an advertisement request. The program corresponding to the browser area may be an HTML file.

  C_ssp_t is a third party cookie of the browser of the client terminal 102. Therefore, even if the browser of the client terminal 102 receives C_ssp_t, C_ssp_t is not stored in the cookie area of the browser. Further, the identifier generated in S312 is not limited to the above cookie ID. The identifier generated in S312 may be a non-overlapping global identifier generated by a program operating on the SSP server 110, and may be, for example, a UUID (Universally Unique Identifier). C_ssp_t, the global identifier, and the UUID may be an example of a first user identifier.

  In S314, the client terminal 102 executes a program corresponding to the browser area. When the above program is executed, the client terminal 102 generates an advertisement request and transmits the advertisement request to the SSP server 110.

  In S330, the SSP server 110 generates a bid request including C_ssp_t as a user ID, and transmits the bid request to one or more DSP servers 120. In S332, each of the one or more DSP servers 120 determines a bid amount and generates a bid response. Each of the one or more DSP servers 120 transmits the generated bid response to the SSP server 110.

  In the present embodiment, each of the one or more DSP servers 120 issues a temporary cookie ID (sometimes abbreviated as C_dsp_t) for each DSP server to identify the client terminal 102. C_dsp_t may be an example of a first user identifier. Each of the one or more DSP servers 120 may store C_dsp_t and C_ssp_t in association with each other.

  According to one embodiment, among the one or more C_dsp_t issued by each of the one or more DSP servers 120, only the C_dsp_t issued by the winning DSP server that won the auction in S334 is transmitted to the browser of the client terminal 102. Is done. When the browser of the client terminal 102 does not permit reading / writing of the third party cookie, C_dsp_t and C_ssp_t stored by the DSP server 120 other than the winner DSP server may not be used in the steps after S334.

  In S334, the SSP server 110 executes an auction and determines a winner DSP based on one or more bid responses transmitted from the one or more DSP servers 120. In S336, the SSP server 110 transmits the advertising tag of the winner DSP to the client terminal 102.

  In S <b> 340, the browser of the client terminal 102 uses the advertisement tag transmitted from the SSP server 110 to transmit an advertisement request to the DSP server 120 that has made a successful bid for displaying the advertisement information in the advertisement space 22.

  In S342, the DSP server 120 executes a procedure for transmitting C_dsp_t to the Web server 142. For example, C_dsp_t is used not for storing as a cookie on the browser side but for uniquely determining an advertisement space. In particular, when stateless exchange is adopted between the client terminal 102 and the DSP server 120, performance can be improved by uniquely identifying the advertising space using a temporary identifier such as C_dsp_t. it can. For example, when stateful exchange is adopted between the client terminal 102 and the DSP server 120, the advertisement space may be specified without using C_dsp_t.

  In one embodiment, the DSP server 120 generates transfer data including C_dsp_t and a redirect instruction. The transfer data may include C_dsp_t as a parameter. For example, the transfer data includes C_dsp_t as a redirect instruction parameter. In another embodiment, the DSP server 120 generates transfer data including C_ssp_t and a redirect instruction. The transfer data may include C_ssp_t as a parameter. For example, the transfer data includes C_ssp_t as a redirect instruction parameter.

  The redirect command may be a command for causing the computer of the client terminal 102 to execute a procedure for switching the access destination of the transfer data to the Web server 104 when executed by the computer of the client terminal 102. The redirect command can be expressed as, for example, http301 / 302 src = “http: // [domain name of Web server 142] / [path name]? T_id = C_dsp_t”. For example, the DSP server 120 transmits the transfer data to the client terminal 102.

  In S344, the browser of the client terminal 102 receives the transfer data transmitted from the DSP server 120. In the present embodiment, a case where transfer data includes C_dsp_t will be described for the purpose of simplifying the description. However, those skilled in the art who have contacted the description of the present specification can understand that identifiers can be synchronized in the same manner as in the present embodiment even if the transfer data includes C_ssp_t.

  The browser of the client terminal 102 transmits the transfer data to the web server 142. At this time, the header of the transfer data includes cookie information related to the domain of the Web server 142. The above cookie information includes C_fp. Transfer data including C_fp in the header may be an example of synchronization information. Thereby, the Web server 142 can associate (i) C_fp with transfer data including (ii) C_dsp_t.

  In S346 and S348, the Web server 142 executes a procedure for transmitting information associated with C_dsp_t and C_fp to the DSP server 120. According to one embodiment, in S346, the Web server 142 generates transfer data including C_dsp_t and C_fp and a redirect command. The transfer data may include C_dsp_t and C_fp as parameters. For example, the transfer data includes C_dsp_t as a redirect instruction parameter.

  The redirect instruction may be an example of an instruction for causing the computer of the client terminal 102 to execute a procedure for switching the access destination of the transfer data to the DSP server 120 when executed by the computer of the client terminal 102. The redirect command can be expressed as, for example, http301 / 302 src = “http: // [domain name of DSP server 120] / [path name]? Id = C_fp & t_id = C_dsp_t”. The DSP server 120 transmits the transfer data to the client terminal 102.

  In S348, the browser of the client terminal 102 receives the transfer data transmitted from the DSP server 120. Here, C_fp included in the transfer data is a cookie written as a First Party Cookie in the cookie area of the browser in session A. Therefore, even when the browser of the client terminal 102 is accessing the Web server 104, C_fp is handled as a Visited Third Party Cookie.

  Thereby, the distribution system 100 can use C_fp as a permanent ID. On the other hand, in the distribution system 100, C_dsp_t can be used as a temporary ID. For example, the distribution system 100 can use C_dsp_t as a session ID for determining an RTB request / response from the SSP server 110.

  The browser of the client terminal 102 transmits the transfer data or a part thereof to the DSP server 120. For example, the browser of the client terminal 102 transmits C_fp and C_dsp_t included in the transfer data to the DSP server 120. The browser of the client terminal 102 causes the computer of the DSP server 120 to execute a procedure (sometimes referred to as targeting) for determining advertisement information to be displayed in the advertising space 22 (sometimes referred to as targeting). )), C_fp and C_dsp_t may be transmitted. For example, the browser of the client terminal 102 is http: // [domain name of DSP server 120] / [path name] / [name of targeting program]? A code expressed as id = C_fp & t_id = C_dsp_t is transmitted.

  In the present embodiment, a case has been described in which the Web server 142 transmits information in which C_dsp_t and C_fp are associated with each other to the DSP server 120 via the client terminal 102. However, the Web server 142 is not limited to this embodiment. In another embodiment, the Web server 142 may directly transmit information associated with C_dsp_t and C_fp to the DSP server 120.

  In S350, the DSP server 120 determines advertisement information to be displayed in the advertisement frame 22. For example, the DSP server 120 refers to a bid history stored in the DSP server 120 using C_fp as a key, and acquires attribute information of the user of the client terminal 102. The DSP server 120 may acquire attribute information of the user of the client terminal 102 with reference to the DMP server 132 using C_fp as a key. The DSP server 120 may extract advertising information to be displayed in the advertising space 22 from a plurality of advertising information stored in the advertising server 134 based on the user attribute information.

  In S <b> 352, the DSP server 120 transmits, to the client terminal 102, an HTML code for calling an advertisement creative determined as advertisement information to be displayed in the advertisement space 22. In S354, the browser of the client terminal 102 accesses the advertisement server 134 and requests the advertisement creative data. In S <b> 356, the advertisement server 134 transmits the advertisement creative to the client terminal 102. The browser of the client terminal 102 displays content including advertisement information on the display of the client terminal 102.
