[Embodiment]
[1. About the outline of the information providing device]
First, with reference to FIG. 1, an example of a process executed by an information providing device, which is an example of a issuing device, will be described. FIG. 1 is a diagram showing an example of processing executed by the information providing device according to the embodiment. In the example shown in FIG. 1, an example of an information providing device that realizes a transaction of an advertising space associated with a predetermined content by issuing a virtual currency corresponding to the advertising space has been described. Further, in the example shown in FIG. 1, an example of a process executed by the information providing device 10 when the company C2 purchases the right to place an advertisement in a predetermined advertising space is described.

The information providing device 10 is an information processing device that executes the issuing process described below, and is realized by, for example, a server device, a cloud system, or the like. Then, the information providing device 10 realizes the transaction of the advertising space associated with the predetermined content by executing the issuing process described below.

[1-1. About inventory]
Here, the advertising space to be traded will be described. For example, in general, in a television program, the sponsor company that has invested to create the television program has the right to advertise in the advertising space attached to the television program. Further, when content such as a movie or a moving image is distributed via the Internet, the advertisement of the purchaser who purchased the advertising space is displayed at a predetermined timing while browsing the content. For example, in the distribution of content via the Internet, the purchaser who purchased the advertising space, the investor who invested in the content to be distributed, or the investor who invested in the content distribution service. The advertisement will be displayed in the inventory. In addition, an advertising space is set in advance for the content such as a web page, and the advertisement to be displayed in the advertising space is determined by the bidding format or the like.

Here, when the popularity of the delivered content increases and the number of viewers increases, the value of the advertisement displayed with the content increases. In other words, by increasing the value of the content, it is thought that the value of the ad space will increase.

On the other hand, when an advertisement is inserted in the middle of the content or a certain content and the advertisement are displayed together, the user may feel a relationship between the content and the advertisement. For example, if an advertisement by the same advertisement provider is displayed in the content that is regularly broadcast or distributed (hereinafter, simply collectively referred to as "provided"), something is between the content and the advertisement provider. It is thought that the user can be impressed by having the relationship of.

Considering the relationship between such content and the inventory that accompanies the content, for example, the inventory that accompanies a certain content is secured in advance, and the inventory is sold after the popularity of the content increases. By doing so, it is considered that a predetermined profit can be obtained. Also, for an ad provider who wants to serve an ad, it may be better to serve the ad along with popular content, even if the cost is high.

Therefore, if the advertising space can be flexibly traded between each advertising provider, it is considered that the value of the advertising space can be improved, and eventually the value of the advertisement can be increased and the advertising effect can be improved.

[1-2. Issuance process]
Therefore, the information providing device 10 executes the following issuing process. First, the information providing device 10 issues a token to which the information of the first right holder who has the right to display the advertisement together with the predetermined content is attached. Then, when the first right holder provides the right to the second right holder, the information providing device 10 provides a token with information indicating that the right has been transferred from the first right holder to the second right holder. Issue.

More specifically, the information providing device 10 issues a token corresponding to the advertising space, and when the right to place an advertisement in the advertising space is transferred, a new token indicating that the right is transferred is issued. For example, the information providing device 10 prepares a virtual currency corresponding to an advertising space and to which a blockchain is attached as a token. Then, the information providing device 10 grants a block containing the information of the first right holder to the block chain of the token, and when the right is transferred from the first right holder to the second right holder, the right is the first right. A block containing information indicating that the person has changed to the second right holder is given to the blockchain of the token. For example, the information providing device 10 attaches a block including information indicating that the right has been transferred from the first right holder to the second right holder at the end of the block chain of the token.

When such a virtual currency is issued as a token, the transfer of rights can be reflected immediately. For example, by exchanging token data between right holders and sending tokens to an advertisement distribution server (not shown) that actually distributes advertisements, the right holder who has the right to distribute advertisements is specified. Such a method is also conceivable. However, in such a method, tokens must be exchanged between right holders and then the tokens must be transmitted to the advertisement distribution server, which takes time and effort to complete the process. In addition, if any of the right holders sends the token to the advertisement distribution server, it may be difficult to transfer the rights thereafter.

On the other hand, if information indicating the transfer of rights is stored in the blockchain of virtual currency and the virtual currency is circulated, by referring to the blockchain, which right holder has the right of the advertising space at that time. It is possible to identify whether it is. Therefore, for example, each right holder can trade the ad space until just before the advertisement is delivered.

[1-3. About an example of issuance processing]
Hereinafter, an example of the issuing process executed by the information providing device 10 will be described with reference to FIG. In the following description, an example of a process executed when the company C2 purchases the right of the advertising space owned by the company C1 will be described.

First, the information providing device 10 accepts the purchase of the advertising space associated with the predetermined content from the company C1 (step S1). In such a case, the information providing device 10 attaches a block storing purchaser information regarding the purchase of the advertising space to the block chain (step S2).

For example, the information providing device 10 generates advertising space information indicating the purchased advertising space. Here, the advertising space information is information for specifying an advertising space to be traded, and is, for example, information indicating, for example, an advertising space that is displayed accompanying which content at which date and time. Further, the information providing device 10 generates information of the company C1 that has purchased the advertising space as purchaser information. Then, the information providing device 10 adds a block including the purchaser information and the purchase limit information to the block chain of the virtual currency. For example, the information providing device 10 trades the latest virtual currency with the purchaser information "company # 1" indicating the purchaser company C1 and the purchase frame information "purchase frame # 1" indicating the purchased advertising space. The third block stored with the data is generated, and the generated third block is added to the end of the virtual currency. Then, the information providing device 10 grants the virtual currency to which the third block is added to the company C1 as a token (step S3).

On the other hand, when the company C2 purchases the right to display the advertisement in the advertisement space indicated by the purchase space information "purchase space # 1", the company C2 requests the company C1 to purchase the advertisement space (step S4). In such a case, the company C1 sells the advertising space indicated by the purchase space information "purchase frame # 1" to the company C2 to the information providing device 10. More specifically, the company C1 sells the virtual currency corresponding to the purchase limit information "purchase limit # 1" to the company C2 (step S5). As an actual process, the company C1 sends a sales notification to the information providing device 10 to the effect that the advertising space indicated by the purchase space information "purchase frame # 1" has been sold to the company C2 (step S6). ).

In such a case, the information providing device 10 attaches a block storing the information of the new purchaser to the block chain (step S7). For example, the information providing device 10 includes purchaser information "company # 2" and purchase slot information "purchase slot # 1" indicating company C2 that has purchased the advertising slot indicated by purchase slot information "purchase slot # 1" from company C1. A fourth block associated with the above is generated, and the generated fourth block is added to the blockchain. Then, the information providing device 10 grants the token to the company C2 (step S8).

[1-4. About tokens]
Here, in the example shown in FIG. 1, the information providing device 10 has the right to the advertising space (hereinafter, referred to as “advertising space # 1”) indicated by the purchasing space information “purchasing space # 1” to the company C1. Was given a token having a blockchain in which the information that the company C1 has was stored. Further, when the company C2 acquires the right of the advertising space # 1 from the company C1, the information providing device 10 adds information to the effect that the company C2 has the right of the advertising space # 1 to the blockchain and obtains a token. Granted to company C2.

When the token is given to each company in this way, the advertisement distribution server can specify which company has the right of the ad space by using the blockchain of the token. For example, when the advertisement distribution server acquires tokens from company C1 and company C2, it specifies the length of the block included in the blockchain of each token, and adopts the token having the longer specified length as a legitimate token. do it. In this way, by adding the transaction history of the advertising space to the blockchain of the token at any time, it is possible to realize the transaction of the advertising space without exchanging the data itself as the token between the companies.

In the example shown in FIG. 1, the information providing device 10 grants the token corresponding to the advertising space to the company C1, and when the right of the advertising space is transferred from the company C1 to the company C2, the token is given to the company C2. Granted. Here, the information providing device 10 may deliver information that can actually be used as a token, but it is not always necessary to deliver the token information to the right holder of the advertising space.

For example, if the virtual currency in which the purchaser information and the purchase slot information are stored in the block of the blockchain is not only the company C1 and the company C2 but also the passage that is open to the public in a tradable form, the right holder of the advertising space. Will be managed by a distributed ledger using the blockchain of virtual currency. When the use of the advertising space is set based on the management by such a distributed ledger, the information providing device 10 does not necessarily have to provide the token information to the companies C1 and C2. In other words, if the information providing device 10 publishes a virtual currency or token in which the advertising space to be traded and the information of the right holder who has traded the advertising space are added to the blockchain, the advertising space can be traded. It is not necessary to provide the right holder with data such as virtual currency and tokens that have a one-to-one correspondence with.

[1-5. About inventory information]
Further, the information providing device 10 may register arbitrary information as advertising space information as long as it is information related to the advertising space to be traded. For example, the information providing device 10 may include date and time information indicating a date and time for displaying an advertisement for a predetermined content in the blockchain as purchase frame information. That is, the information providing device 10 may register in the blockchain date and time information indicating the date and time when the advertisement is displayed in the advertisement space as the information indicating the advertisement space that has become the transaction target. For example, the information providing device 10 issues a token with date and time information and information of the first right holder who has the right to display an advertisement at the date and time indicated by the date and time information, and the first right holder issues the date and time indicated by the date and time information. When providing the right to display an advertisement to the second right holder, a token may be issued with information indicating that the right has been transferred from the first right holder to the second right holder together with the date and time information.

Further, the information providing device 10 may include in the blockchain the reward amount provided to the company C1 when the company C2 purchases the advertising space from the company C1, that is, the information indicating the purchase price of the advertising space. .. For example, the information providing device 10 further imparts information indicating the content of the reward for the first right holder providing the right to the second right holder, together with the information indicating the second right holder who purchased the advertising space. You may issue a token.

Further, the information providing device 10 may issue a token to which information indicating the content of the reward for the acquisition of the right of the advertising space by the company C1 is further added. For example, in the information providing device 10, when the company C1 invests in the creation and distribution of a certain content and an advertising space accompanying the content is generated, the information indicating the advertising space and the right of the advertising space are generated. In addition to the information indicating that the company C1 has the information, information such as the investment amount of the company C1 and whether the company C1 has invested in the creation of the content or the distribution may be added to the blockchain.

In addition to the above-mentioned information, the information providing device 10 may add arbitrary information to the blockchain. For example, the information providing device 10 includes information about the right holder such as the name and location of each right holder who has the right of the advertising space, the size (display size) of the advertising content that can be displayed in the advertising space, the resolution, the playback time, and the like. Information on the advertising space, information on the corresponding content such as the name of the content corresponding to the advertising space, and the like may be stored in the blockchain.

[1-6. About release to the market]
Here, the information providing device 10 may regard the transaction of the virtual currency owned by each right holder as the transaction of the advertising space by associating the virtual currency with the advertising space. For example, when the company C1 has the right of the advertising space # 1, the information providing device 10 provides the token corresponding to the advertising space # 1 to the company C1.

On the other hand, when the company C1 wants to sell the advertising space # 1, it sells the token corresponding to the advertising space # 1 to the exchange that trades tokens and the like. Then, when the company C2 purchases the exhibited token, the information providing device 10 adds a blockchain including information that the company C2 is the right holder to the exhibited token, so that the transaction of the advertising space can be performed. May be realized.

[2. About an example of functional configuration]
Hereinafter, an example of the functional configuration of the information providing device 10 that realizes the above-mentioned issuing process will be described. FIG. 2 is a diagram showing a configuration example of the information providing device according to the embodiment. As shown in FIG. 2, the information providing device 10 includes a communication unit 20, a storage unit 30, and a control unit 40.

The communication unit 20 is realized by, for example, a NIC (Network Interface Card) or the like. Then, the communication unit 20 is connected to the network N by wire or wirelessly, and transmits / receives information to / from an arbitrary device.

The storage unit 30 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disk. Further, the storage unit 30 stores the advertising space database 31.

Information about the advertising space is registered in the advertising space database 31. For example, FIG. 3 is a diagram showing an example of information registered in the advertising space database relating to the embodiment. As shown in FIG. 3, information having items such as "advertising space ID (Identifier)", "content", "core information", and "owner information" is registered in the advertising space database 31. In addition to the information shown in FIG. 3, arbitrary information regarding the advertising space may be registered in the advertising space database 31.

Here, the "advertising space ID" is an identifier for identifying the advertising space. Further, the "content" is information indicating the content corresponding to the advertising space indicated by the "advertising space ID". Further, the "period information" is information indicating a period (date and time) during which an advertisement can be displayed for the advertisement space indicated by the associated "advertisement space ID". Further, the "owner information" is information indicating a right holder who has the right to display an advertisement for the advertisement space indicated by the associated "advertisement space ID". In the example shown in FIG. 3, conceptual values such as "advertising space # 1", "content # 1", "period # 1", and "company # 1" are described, but in reality, the advertising space is described. Numerical values and character strings for identifying the content, numerical values indicating the date and time when the advertisement can be displayed, numerical values and character strings indicating the right holder, and the like are registered.

For example, in the example shown in FIG. 3, the ad space database 31 has the ad space ID “advertisement space # 1”, the content “content # 1”, the period information “period # 1”, and the owner information “company # 1”. Are registered in association with each other. Such information is such that the ad space indicated by the ad space ID "advertisement space # 1" is an ad space attached to the content "content # 1", and the advertisement is placed within the period indicated by the period information "period # 1". Indicates that it is an advertising space for display. Further, such information indicates that the right holder indicated by the owner information "company # 1" owns the right to display the advertisement in the advertising space indicated by the advertising space ID "advertising space # 1". In other words, such information is provided by the right holder indicated by the owner information "company # 1" during the period indicated by the period information "period # 1" in the advertising space attached to the content indicated by the content "content # 1". Indicates that you own the right to display advertisements.

Returning to FIG. 2, the explanation will be continued. The control unit 40 is a controller, and for example, various programs stored in a storage device inside the information providing device 10 by a processor such as a CPU (Central Processing Unit) or an MPU (Micro Processing Unit) are RAM or the like. Is realized by executing as a work area. Further, the control unit 40 is a controller, and may be realized by, for example, an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

As shown in FIG. 3, the control unit 40 has a management unit 41, a reception unit 42, a generation unit 43, and a issuing unit 44. The management unit 41 executes various types of management related to the transaction of the advertising space. For example, when the management unit 41 accepts the registration of the advertising space from the terminal device used by the right holder, the management unit 41 registers the advertising space in the advertising space database 31.

For example, the management unit 41 receives information about the ad space and information about the right holder from the first right holder of the ad space. In such a case, the management unit 41 registers the information related to the advertising space and the information of the right holder in the ad space database 31 in association with each other, and requests the reception unit 42 to issue a new token. When the management unit 41 receives information about the advertising space to be exhibited as a transaction target from the right holder, the management unit 41 registers the information about the advertising space and the information of the right holder in the advertising space database 31 and issues a new token. You may ask.

The reception unit 42 accepts the transfer of the rights of the advertising space. For example, the reception unit 42 receives information on the advertising space to which the rights are transferred and information on the second right holder to which the rights are transferred from the first right holder who has the rights to the advertising space. In such a case, the reception unit 42 updates the information registered in the ad space database 31, and also updates the information of the ad space to which the right is transferred and the information of the second right holder to which the right is transferred. Notify the generation unit 43. Further, when the reception unit 42 receives the issuance request of the new token from the management unit 41, the reception unit 42 notifies the generation unit 43 of the information of the advertising space and the information of the right holder.

The generation unit 43 generates a blockchain to be given to the token. More specifically, the generation unit 43 generates a block including information indicating the advertising space to be traded and information indicating the right holder of the advertising space, and adds it to the blockchain given to the token at any time. ..

For example, when the generation unit 43 receives the information of the advertising space corresponding to the new token and the information of the right holder from the reception unit 42, the received information is used as the purchase space information and the purchaser information, and the blockchain is subjected to the information. In the block to be added next, the purchase limit information and the purchaser information are registered in association with each other. Further, even when the generation unit 43 receives the information of the advertising space to which the rights are transferred and the information of the second right holder to which the rights are transferred, the received information is used as the purchase space information and the purchaser information. , Register in association with the block to be added next. Then, the generation unit 43 adds a new block to the end of the block chain of each token at a predetermined timing.

The issuing unit 44 issues a token in which a new block is added to the end of the block chain by the generating unit 43. For example, when the information of the ad space corresponding to the new token and the information of the right holder are added to the blockchain, the issuing unit 44 attaches the blockchain to the new token and attaches the blockchain to the advertisement corresponding to the new token. A new token will be given to the right holder of the slot. Further, the issuing unit 44 grants such a blockchain when the information of the advertising space to which the right is transferred and the information of the second right holder to which the right is transferred are added to the blockchain. Provide the token to the second right holder.

That is, when the issuing unit 44 issues a token with the information of the first right holder who has the right to display the advertisement together with the predetermined content, and the first right holder provides the right to the second right holder. Issuees a token with information indicating that the right has been transferred from the first right holder to the second right holder. For example, the issuing unit 44 issues a token added to the blockchain by a block containing the information of the first right holder, and also includes a block containing information indicating that the right has been transferred from the first right holder to the second right holder. Issue the token added to the blockchain. More specifically, the issuing unit 44 issues a token at the end of the blockchain to which a block containing information indicating that the right has been transferred from the first right holder to the second right holder is added.

When the date and time information indicating the date and time for displaying the advertisement in the advertisement space is added to the block as the information of the advertisement space, the issuing unit 44 includes the date and time information indicating the date and time for displaying the advertisement for the predetermined content. A token will be issued with the information of the first right holder who has the right to display the advertisement at the date and time indicated by the date and time information. Then, when the first right holder provides the second right holder with the right to display the advertisement at the date and time indicated by the date and time information, the issuing unit 44 shifts the right from the first right holder to the second right holder. A token with information indicating that effect will be issued.

The issuing unit 44 may issue a token further provided with information indicating the content of the reward for the first right holder providing the right to the second right holder, and the first right holder grants the right. You may issue a token with additional information indicating the content of the reward for the acquisition. For example, the generation unit 43 may register information indicating the sales amount when the first right holder sells the advertising space to the second right holder in the block, and the first right holder acquires the right of the advertising space. Information indicating the amount paid at the time of payment may be registered in the block.
