[Embodiment]
An information processing system (hereinafter referred to as "this system") according to one embodiment of the present invention will be described with reference to the drawings.

<Description of overview>
First, referring to FIG. 1, a service to which this system is applied (hereinafter referred to as "this service") will be specifically described.
FIG. 1 is a diagram illustrating an overview of services to which an information processing system according to an embodiment of the present invention is applied.

This service is a service provided incidentally in a game including trading of predetermined media (hereinafter referred to as "items"). Specifically, for example, as shown in Figure 1, in this service, various technologies represented by blockchain are used to generate an "appraisal" for items in the game, etc., so that the legitimacy of the item ( It is possible to guarantee that there is no fraud in the acquisition or transaction). Various game processes are executed depending on whether the certificate has been generated and the contents of the certificate.

Here, the game in this embodiment is, for example, an MMO (Massively Multiplayer Online) type network game. These types of games generally adopt specifications in which multiple information processing terminals connected via a network share a virtual space and multiple users cooperate to achieve a predetermined goal. It is In order to facilitate the achievement of those objectives, many items that can be used in the game are set. Among the items, there are cases where items with extremely high rarity are set such that only a certain number or less can exist in the game at the same time.
For this reason, in MMO-type network games, free transactions using in-game currency may be permitted among users, including items with high rarity. That is, the game in this embodiment is typically an MMO-type network game in which free trading of items is permitted within the game.

Also, the technology for reducing the possibility of falsification of information may be, for example, a technology related to blockchain or various distributed ledgers, or a combination thereof. In this embodiment, by appropriately applying blockchain technology to various types of information (e.g. transaction information, appraisals, etc.), it is possible to more easily prevent falsification of information and guarantee the legitimacy of items. becomes.
Specifically, for example, transaction information for item X may function as blocks in a blockchain. Specifically, for example, the transaction information of item X in each block includes information such as a hash value calculated from the previous block, so that each block is linked and stored in various databases.
Various processing related to the blockchain may be performed by the server 1 described later, or may be performed by another information processing device different from the server 1 described later, a cloud-type server, or the like.

Furthermore, this service can be used in combination with a technology called NFT (Non-Fungible Token). NFT uses blockchain technology to generate a unique token that cannot be replaced (difficult to duplicate) and can be given to any target. By linking this with various in-game assets (items, characters, etc.), even in-game data can be used as irreplaceable assets in a sense similar to assets in the real world. I can expect it. Therefore, NFTs are currently being attempted to be adopted in many games and the like. Also in this service, by applying NFT by any method, it is possible to provide a game system with even higher gameplay.

Based on the above premise, the concept of this service will be specifically described with reference to FIG.
In the example of FIG. 1, various types of information (hereinafter referred to as "transaction information") regarding past transactions of item X performed in the game are recorded as a blockchain, ensuring a situation in which falsification of information is difficult. . Also, it has been confirmed that no fraud has been committed based on the user's game play record.
In the server 1, which will be described later, if these two conditions are met, a "certificate" that guarantees that these conditions are met is generated. In this service, various game processes are executed according to the generation of this "certificate" or the content of the generated certificate.
Note that this "certificate" may be presented to the user at any timing. This allows the user to believe in the legitimacy of item X and play the game.

Further, in the present embodiment, in-game fraud refers to various types of fraud that can be extracted based on various types of game-related information (hereinafter referred to as “game information”) including transaction information, user play records, and the like. Specifically, for example, trading at an unbalanced price accompanied by fraud or intimidation, falsification of random numbers or table information when acquiring items, etc. fall under this category.

To summarize the above, in this service, the "certificate" is generated only when it is guaranteed that the transaction information of item X has not been tampered with and that the game has not been tampered with. That is, the item X associated with the "certificate" is guaranteed to be less likely to be fraudulent or tampered with when the item is traded. In this service, by using the "Certificate" with such properties, it is possible to easily show the legitimacy of the item X linked to the "Certificate", and to check whether or not the certificate is generated. Executes different game processing depending on the As a result, the present service can provide users with a highly convenient and deep game system.

<Functional configuration>
FIG. 4 is a functional block diagram showing an example of functional configurations of the server of FIG. 3 and the user terminal of FIG.
As shown in FIG. 4, the control unit 11 of the server 1 executes various programs and the like to obtain game information acquisition means 60, transaction information management means 61, fraud determination means 62, association means 63, and appraisal means. It functions as book request acquisition means 64 , certificate generation means 65 , and game processing management means 66 .
Here, in one area of the storage unit 18 of the server 1, a game information DB 300 and an association information DB 400 are provided.

The game information acquisition means 60 of the server 1 acquires various information related to the game transmitted from each of the user terminals 2, that is, game information.
Here, the game information includes information on the past history of item transactions performed in the game, that is, transaction information, and information on inputs from the user in the game (hereinafter referred to as “input information, etc.”). be Note that the input information includes information about the time when the input information was acquired.
Also, the game information acquiring means 60 stores the acquired game information in the game information DB 300 .

Transaction information management means 61 manages game information (especially transaction information) stored in the game information DB 300 .
That is, the transaction information management means 61 takes measures to reduce the possibility of tampering of the game information among the game information stored in the game information DB 300 (hereinafter referred to as "falsification prevention measures"). apply.
Specifically, for example, the transaction information management means 61 utilizes an existing service or a server installed on a cloud (not shown), etc., makes the transaction information function as each block of the block chain, and in a state where each block is connected It stores in game information DB300.
Transaction information management means 61 also includes falsification prevention means 71 . The tampering prevention means 71 confirms that the transaction information is tampered with.

The fraud determination means 62 determines whether or not fraud has been committed in the game based on the game information. That is, the fraud determination means 62 determines whether or not the game information satisfies a predetermined condition.
Specifically, for example, the fraudulent determination means 62 determines whether fraudulent in-game fraud such as fraudulent or intimidating transactions at unbalanced market prices, falsification of random numbers or table information at the time of item acquisition, etc. is performed based on the game information. determine whether or not
The type of fraud to be determined and the method of determination are not particularly limited, and may be arbitrarily determined by the provider of this service.

The associating means 63 associates the game information managed by the transaction information managing means 61 and the determination result of whether or not there is fraud determined by the fraud determining means 62 with the target item, and stores them in the related information DB 400 .

Here, in this service, when the user wishes to generate a certificate, which will be described later, the user transmits information indicating that the user wishes to generate a certificate (hereinafter referred to as "certificate request") via the user terminal 2. ). The user terminal 2 then transmits the input certificate request to the server 1 .
Therefore, the certification request acquisition unit 64 acquires the certification request transmitted from the user terminal 2 via the communication unit 19 .

If the falsification prevention means 71 confirms that the transaction information has been tampered with and the fraud determination means 62 determines that fraud has not occurred, the certificate generation means 65 indicates that fact. Generate a Certificate of Authenticity.
Here, the certificate generation means 65 may further improve the value of the certificate by applying a tampering prevention measure to the generated certificate, or applying a technology to ensure non-substitutability. .
Specifically, for example, the certificate generation means 65 uses a technology related to NFT to generate and grant a unique token that cannot be replaced (difficult to duplicate) for the generated certificate good.
As a result, the rarity of the appraisal is improved, and the possibility of value fluctuation due to falsification of information or malicious intent can be reduced. Therefore, for example, even if the generated certificate is used in other games or in the real world, it can be expected that the value will not change significantly.
Note that the certificate generating means 65 may generate a certificate for each item associated with the transaction information and the result of the determination of the presence or absence of fraud. Further, if there are a plurality of games to be played, the certification generating means 65 may generate a certification for each game.

The game processing management means 66 determines the content of the predetermined process to be executed in the game based on the certificate generated by the certificate generation means 65 .
In other words, the game processing management means 66 executes a predetermined process related to the game on the condition that the transaction information has not been tampered with and that it is guaranteed that no fraud has been committed as a result of the determination of the presence or absence of fraud. do.
Here, the predetermined processing executed in the game includes, for example, the following processing.
(1) When the content of the transfer of the target item is determined in advance, the game processing related to the transfer of the item can be executed according to the content of the transfer determined in advance.
Specifically, for example, in an MMO-type network game, when a user retires from the game, there are cases where the items owned by the user are distributed to other users in an arbitrary distribution. In this way, when transferees of a large number of items are determined in advance, game processing such as restricting the transfer of items can be executed according to the details.
(2) It is possible to execute game processing for determining the effect or content of an item in response to a change in the subject who owns the target item.
Specifically, for example, in transaction information that has undergone tampering prevention measures, changes in the entity that owns the item are accurately recorded. In such a case, if there are many subjects who own the item, if the item is owned by a specific subject, or if the item is owned by a subject who has a special relationship with the user, the effect of the item will be reduced. Predetermined game processing such as strengthening can be executed.
(3) It is possible to execute a game process that permits the transaction of the target item when the certificate is generated, and prohibits the transaction of the target item when the certificate is not generated.
(4) It is possible to execute game processing that permits the use of the target item when the certificate is generated, and prohibits the use of the target item when the certificate is not generated.
The game processing management means 66 transmits information regarding the content of the determined processing (hereinafter referred to as “game processing information”) to the user terminal 2 .

Next, the functional configuration of the user terminal 2 will be explained.
As shown in FIG. 4, the control unit 100 of the user terminal 2 functions as a game processing executing means 200 by executing various programs.
The game processing executing means 200 executes various types of processing related to the game.
Specifically, for example, the game processing executing means 200 reads data such as virtual game space objects and textures included in the game data from a storage unit (not shown) or the like according to various types of information input by the user, and executes the game program. At the same time, various information related to the game such as two-dimensional or three-dimensional images and sounds are generated.
In addition, the game processing executing means 200 controls the positions and actions of the characters in the game according to the user's operations.

Here, the game processing execution means 200 includes game information management means 220 , certification request management means 221 , and certification related processing means 222 .

<Specific example>
Here, an example of specific processing contents determined by the game processing management means 66 will be described in detail with reference to FIG.
FIG. 5 is a diagram showing an example of game processing determined by the server of FIG.
For example, item Y shown in FIG. 5 is a special cursed item that, when used in a game, causes a large amount of damage that can be fatal with a probability of 1/100.
This item Y can be used continuously, for example, even if the character is unlucky and suffers a large amount of damage, as long as the character using it survives. On the other hand, however, if the character using the item dies due to being unable to withstand the large amount of damage, the item is no longer owned by that character and becomes available for other characters (can be dropped by other characters).
Item Y is so designed that the performance of the item is strengthened each time the character using it undergoes a series of processes in which the character receives great damage, dies, and is acquired by another character. Such a specification would be difficult to achieve without the feature of this service that all history of the subject who owns item Y is accurately maintained. It can be said that the specifications of

<Other embodiments>
Here, the background of the present invention will be briefly supplemented.
Conventionally, there have been known attempts to apply blockchain and NFT to games by using them for item transactions and the like. In games using such technology, there are many attempts to manage items and in-game currency in such a manner that they are redeemable for real currency, virtual currency, and the like.
However, in conventional games of this type, the use of block chains for transaction information is limited to the degree of preventing tampering. It cannot be expected to function effectively against all kinds of fraud, including fraud in the game, specifically analog fraud that can occur when acquiring or trading items.
Here, analog fraud refers to, for example, ``when a transaction is made with an item with a value lower than the market price in the game due to threats, etc.,'' transactions, transfer of accounts (transactions by a transferred account), or other transactions that violate the terms of the game, or items that are not provided despite a promise to carry out a transaction. be.
In other words, as long as blockchain and NFT technology is used for items and the like, it is possible to verify the legitimacy of game play from the information stored in the blockchain. However, to put it the other way around, there was a limit that it could only verify the information and validity obtained from it.
Therefore, in this service, the server 1 separately executes tampering prevention measures using blockchain and the verification of fraud that may occur in the game, and stores the contents and results in association with items and the like. Then, the server 1 generates an appraisal only when the transaction history related to the item has not been tampered with or any other fraud has occurred.
In other words, for example, before trading an item, an appraisal certificate is generated that guarantees that there is no fraudulent acquisition or transaction of the item. Various game processing such as confirmation can be executed.
Therefore, the provider of the present service can not only provide the user with a game system with a higher game quality, but also can provide the user who does not commit fraud with a convincing merit.

Here, a brief description will be given of blockchain technology that can also be used in the above-described embodiments.
Blockchain is a general term for a database that stores data by configuring data units called blocks and connecting them like a chain, or various technologies related to it. Each block contains hashes, timestamps, transactions (transaction information), etc. linked to the previous block to efficiently and verifiably record the transaction between the covered parties. can be done.
Also, these blockchains are typically managed by decentralized networks such as P2P (Peer to Peer) and cannot be retroactively changed without changing all subsequent blocks. Therefore, falsification of information stored as a blockchain is considered extremely difficult in reality, although not impossible.
Please refer to the following Non-Patent Document 1 for details of technologies such as the blockchain and bitcoin systems.

Also, for example, in the above-described embodiment, one certificate is generated for the target game, but the present invention is not particularly limited to this.
That is, multiple certificates may be generated in one game, or multiple certificates may be generated in a game other than the target game. Here, when executing various game processes based on the certificate generated in another game, the server 1 may determine the contents of the game process to be executed, including at least the following two concepts.
(1) A certificate generated in another game may be treated in the same way as a certificate generated in a target game, assuming that it is correct in principle, and game processing to be executed may be determined.
(2) In principle, the contents of the certificate generated in other games are confirmed, and only when the content of the certificate is confirmed to be correct, it will be treated and executed in the same way as the certificate generated in the target game. Determine game processing.
Furthermore, if the certificate is generated in another game, the content or effect of the item in the target game, or other execution based on the effect or content of the item in the other game for which the certificate was generated You may determine the content of the game processing to perform.

Specifically, for example, the following effects are expected when using the certificate in another game.
(1) Items acquired in another game can be obtained (synthesized) in the target game.
(2) One item owned by the user can be used in common in different games.
In this case, when the item is nurtured, for example, the item may be strengthened commonly in a plurality of games, or the strength of the item may be managed for each individual game. Furthermore, the above two methods are adopted in combination, for example, the strength of items is commonly managed between arbitrary games, and the strength of items is managed individually in other games. good too. In addition, when an item is commonly used in a plurality of games, the item may be shared by games of different game genres. Conversely, a character (medium) that can only be used in one game, such as transferring a player from a soccer game to a baseball game, may be obtainable (synthesized) in another game.
(3) In addition, if an item can be used in common in multiple games, it may be possible to adopt a specification in which the item disappears when the item is used (acquired/combined) in any game, A specification that does not disappear may be adopted.

For example, RPG (Role Playing Game), simulation game, fighting game, sports game and card game, battle royale (symmetrical type, asymmetrical type), FPS (First Person Shooter), RTS (Real Time Strategy), MOBA (Multiplayer online battle arena), music games, or any other game genre.

Also, for example, in the above-described embodiment, the certificate is generated according to the user's request, but the present invention is not particularly limited to this.
That is, the certificate may be generated (confirmed whether it can be generated) at any timing determined by the provider of this service, regardless of the request from the user, or for example, at a certain time interval Generation (confirmation of whether generation is possible) may be performed periodically.

Also, for example, the series of processes described above can be executed by hardware or by software.
In other words, the functional configuration of FIG. 4 is merely an example and is not particularly limited.
That is, it is sufficient that the information processing system has a function capable of executing the above-described series of processes as a whole, and what kind of functional blocks are used to realize this function is not particularly limited to the example in FIG. Also, the locations of the functional blocks are not particularly limited to those shown in FIG. 4, and may be arbitrary.
Also, one functional block may be composed of hardware alone, software alone, or a combination thereof.

Further, for example, the number and users of various types of hardware (server 1 and user terminal 2) that make up this system are arbitrary, and the system may be configured including other hardware. Specifically, for example, the same computer or the like may be adopted as the server 1 and the user terminal 2 .

Further, for example, when a series of processes is executed by software, a program constituting the software is installed in a computer or the like from a network or a recording medium.
The computer may be a computer built into dedicated hardware.
Also, the computer may be a computer capable of executing various functions by installing various programs, such as a server, a general-purpose smart phone, or a personal computer.
That is, for example, any computer, any mobile terminal such as a smart phone, any game machine, or the like may be freely adopted as the various hardware (the server 1 and the user terminal 2) in the above-described embodiments. Furthermore, any combination of types and contents of various input units and various output units may be adopted.

Also, for example, although the description was omitted in the above-described embodiment, the timing at which the fraud determination unit 62 determines the presence or absence of fraud is not particularly limited.
For example, the server 1 may determine the presence or absence of fraud at an arbitrary timing, or may determine the presence or absence of fraud at the timing of obtaining the certificate request.

Also, for example, in the above-described embodiment, generation of the certificate (and storage of information in the association information DB 400) is described as being performed for each item, but the present invention is not particularly limited to this.
For example, generation of a certificate (and storage of information in the association information DB 400) may be performed for each of a plurality of items, or one certificate may be generated for each game.

Further, for example, a recording medium containing such a program is not only constituted by a removable medium (not shown) that is provided separately from the main body of the device for providing the program to the player, but also is pre-installed in the main body of the device. It consists of a recording medium, etc. provided to the player in

In this specification, the steps of writing a program recorded on a recording medium are not only processes that are performed chronologically in that order, but also processes that are not necessarily chronologically processed, and that are performed in parallel or individually.
