Hereinafter, an information processing device, a communication system, a communication method, and a program according to embodiments will be described with reference to the drawings.

FIG. 1 is a system configuration diagram showing an example of the configuration of an information processing system 1 according to an embodiment. The information processing system 1 includes, for example, an individual identification server 10, a registration terminal 20, a game server 30, and a plurality of player terminals 40 (player terminals 40-1, 40-2, . . . 40-N). N is any natural number.

Each device (the individual identification server 10, the registration terminal 20, the game server 30, and the plurality of player terminals 40) in the information processing system 1 is connected to be able to communicate with each other via the communication network NW. Although FIG. 1 shows a case where there is one individual identification server 10, one registration terminal 20, and one game server 30, the information processing system 1 may be configured to include a plurality of these devices. may be done. Further, the information processing system 1 may be configured to include one player terminal 40. Furthermore, the individual identification server 10 and the game server 30 may be configured as a single server device.

The information processing system 1 is a system that provides content. The content in this embodiment is one that expresses audiovisual expressions such as characters, images, graphics, audio, and video in a digital format, and includes, for example, game content that combines these audiovisual expressions, or augmented reality. It is. In the following, a case where the content is a card game (hereinafter simply referred to as a game) will be explained as an example, but as mentioned above, the content is of course not limited to a game. Note that the game may be a box game content provided by a game device, or online content provided to a smartphone of a game player (hereinafter simply referred to as a player) via a communication network NW. It's okay.

The individual identification server 10 performs individual identification of cards using known image recognition technology. In this embodiment, a barcode is attached to the card to uniquely identify the card.

In the following description, an example will be explained in which the barcode is a printed matter manufactured by printing, but the present invention is not limited thereto. The barcode may be expressed in a manner that allows at least individual differences to occur, and may be expressed by painting, marking, etc. in addition to printing.

In this embodiment, a barcode is attached to the card, for example, by printing a barcode on the card, or pasting a sticker on which the barcode is printed on the card.

Here, the barcode is visible as part of the card's appearance. Furthermore, barcodes may differ in printing smearing, for example, due to differences in the printing environment during the printing process. In other words, the barcode attached to the card is an example of "individual information" because the barcode is an appearance of the card and can vary from one card to another. Further, a barcode is an example of an "identification code."

An identification number that uniquely identifies the card before shipping is registered in the individual identification server 10 by the registration terminal 20. The individual identification server 10 extracts the individual differences (an example of "feature point data") due to the printing of the barcode attached to the card from the image data of the card corresponding to the registered identification number, and uses the extracted feature point data. It is stored in association with the identification number.
The individual identification server 10 performs authenticity determination when a player plays a game. Authenticity determination is a process of determining whether a card used in a game is a genuine card. The individual identification server 10 acquires image data of cards used in the game from the player terminal 40. The individual identification server 10 extracts feature point data from the acquired image data, and performs authenticity determination by comparing the extracted feature point data with registered feature point data.

The registration terminal 20 performs card registration before shipping. The registration terminal 20 is, for example, a terminal device such as a computer installed at a card manufacturing factory. The registration terminal 20 images the barcode attached to the card during the card manufacturing process. The registration terminal 20 transmits the image data of the barcode to the individual identification server 10 in association with the card. Card registration is performed by storing the image data from the registration terminal 20 on the individual identification server 10 side.

The game server 30 provides game content to players. In response to a request from the player terminal 40 to start a game, the game server 30 acquires information such as the player and the cards and items held by the player. The game server 30 provides game content when the player's card is determined to be genuine based on the result of the card authenticity determination by the individual identification server 10.

The player terminal 40 is a terminal device on which game content is displayed. The player terminal 40 is, for example, a player's mobile phone, smartphone, tablet terminal, game-dedicated terminal, head-mounted terminal, smart glasses terminal, notebook or desktop personal computer, or the like. The player terminal 40 is operated by the player and communicates with the game server 30. In response to a request from the game server 30, the player terminal 40 transmits image data obtained by capturing an image of a card used in the game. The player terminal 40 can acquire game content from the game server 30 and play the game if the card used in the game is determined to be genuine. Here, the cards used in the game are cards that have been distributed on the market after being shipped and held by players.

For example, the feature point data is data that associates each pixel in the image data with the presence or absence of blurred printing. The printing environment here includes vibrations of the printing device, humidity during printing, consumables such as ink, line speed in the printing process, printing tolerances, variations in printed matter, and the like. Utilizing the fact that individual differences occur in each print depending on these differences in printing environment, the feature point data extraction unit 131 extracts the individual differences of each barcode as feature point data. The feature point data is information specific to an individual, and is information that uniquely identifies that individual.

The feature point data extraction unit 131 registers feature point data (hereinafter referred to as first feature point data) extracted from image data of a card to be registered acquired from the registration terminal 20 (hereinafter referred to as first image data). It is stored in the card characteristic information storage section 120.
The feature point data extraction unit 131 extracts feature point data (hereinafter referred to as first feature point data) extracted from the image data of the player's card (hereinafter referred to as second image data) acquired from the player terminal 40 as player card features. It is stored in the information storage unit 121 and output to the authenticity determination unit 132.

The authenticity determination unit 132 determines whether the player's card is a genuine product (registered card). The authenticity determination unit 132 refers to the registered card feature information storage unit 120 based on the second feature point data acquired from the feature point data extraction unit 131. If the first feature point data stored in the registered card feature information storage section 120 matches the second feature point data, the authenticity determination section 132 determines that the player's card corresponding to the second feature point data is It is determined that the product is genuine. On the other hand, if the first feature point data stored in the registered card feature information storage section 120 does not match the second feature point data, the authenticity determination section 132 determines whether the player's identity corresponding to the second feature point data is The card is determined to be a non-genuine product. Here, the expression that the first feature point data and the second feature point data match includes a case where the first feature point data and the second feature point data match and a case where both are similar. "Similar" here refers to a case where the tendency of the data in both is similar, and for example, a case where a difference in a point where the two differ is within a predetermined range. The authenticity determining section 132 stores the determined result in the player card characteristic information storage section 121.

The statistics deriving unit 133 derives statistics from the second image data and/or the second feature point data. A statistic is a numerical value that is obtained by applying a statistical algorithm to data and indicates the characteristics of that data. The statistic deriving unit 133 derives, for example, a representative value of the color of each pixel in the second image data as a statistic. The representative value is an average value obtained by simple addition, an average value obtained by weighted addition, or a median value. The statistic deriving unit 133 causes the player card characteristic information storage unit 121 to store the derived statistic.

In the above description, the barcode attached to the card is used as an object for individual identification, but the present invention is not limited to this. Barcodes attached to figures and toys may be used for individual identification. In other words, a card is an example of a "product."
Further, the object of individual identification is not limited to barcodes, and may be QR codes (registered trademark), specific labels, marks, shapes, etc.

In the above description, an example has been described in which it is determined whether the cards before and after shipping are the same individual, but the present invention is not limited thereto. It is only necessary that the card be registered as a genuine product at least before the player requests the start of the game and sends the image data of the card. For example, the player may register after purchasing a card at a store that sells genuine products. In this case, the registration terminal 20 in the information processing system 1 can be omitted. That is, before shipping is an example of a "first point in time", and a card before shipping is an example of a "first product". Further, the period after shipping is an example of a "second time point," and the card used in the game is an example of a "second product."

Although the case where statistics are used as random numbers is illustrated above, the present invention is not limited to this. The statistics may be reflected in various parameters used in the game, such as character ability values. In this case, for example, the content control unit 333 determines a numerical value in a predetermined range (for example, 0.8 to 1.2) according to the statistical amount, and applies it to the ability value of the character indicated in the card attribute information. The ability values may be weighted by multiplying them by the determined values. Thereby, the character's ability values change each time the game is played, making it possible to enhance the gameplay.

In the above example, the statistics deriving unit 133 of the individual identification server 10 derives the statistics, but the game server 30 may derive the statistics from image data. Furthermore, the statistics may be derived using each piece of image data obtained each time the game is played. For example, the statistic may be a value corresponding to the difference between certain image data and each pixel in previously captured image data. Alternatively, the degree of variation from the average value or deviation value of the image data and the image data obtained up to that point may be used as the statistic.

In the above example, the game performance is enhanced using statistics, but the game performance may also be enhanced using attribute information of individually identified cards. For example, if the player's card is a card sold only at a specific venue, points are awarded. Or. If the player's card is a rapidly growing card, an item may be presented to the player.

Moreover, by performing the above-described authenticity determination, it is possible to identify individual cards even if the cards have the same pattern printed on them. This produces the following effects.

Effects of a configuration that performs individual identification of cards held by players:
(1) Player information and card information owned by the player can be stored in association with each other, and the game progress of the player can be recorded. This makes it possible, for example, to share a player's game progress record between different hardware. Furthermore, it is possible to carry over the progress record of the game even if the game software is upgraded.

Effects of improving game playability due to the configuration that performs individual identification for each card:
(2) Hidden parameters can be set on cards. By managing each card's individual value and compatibility with other cards as hidden parameters, by linking it to the card's individual identification, even cards with the same pattern printed on them can behave differently. This can improve the gameplay.
(3) A record of growth can be set on the card. By managing the growth of each card by linking it to the card's individual identification each time it is used in the game, it is possible to use the card with the growth content when restarting the game next time. can.
(4) For cards that have a limited number of uses (for example, an ability value increase card that can improve a character's ability values only a predetermined number of times), the number of uses can be managed for each card. Even if the cards have the same pattern printed on them, the number of times they can be used can be managed individually.
(5) The number of times the card can be used can be restored by charging. For example, conventionally, if the number of uses of a card has been used up, the card cannot be used in a game, and a new card must be purchased. However, in this embodiment, by linking billing information to the individual identification of the card, it is possible to restore the number of uses of the card that has been used up.
(6) Card trading can be appropriately managed. For example, even if a card grown by a player is transferred to another player, the card can be used by the transferred player with the content after the growth.

Effects of preventing counterfeiting through a configuration that performs individual identification for each card:
(7) Using the camera function of the player's smartphone or the like, it is possible to easily detect duplication by copying, etc., and it is possible to easily determine authenticity.
(8) By registering cards before shipping, it is possible to identify cards that have been illegally extracted or misappropriated during the distribution stage. It is also possible to trace the flow of resale by using stolen cards.

Other effects of the configuration that performs individual identification for each card:
(9) It is possible to tie-up with other products. For example, by using a smartphone to capture an image of the barcode attached to a product targeted for a campaign, a campaign can be developed for each individual product.
(10) It is possible to understand the playing status of the player by linking it to the individual identification of the card, and it is possible to visualize where and how the player is playing and utilize it as big data.
(11) An individually identified card can be used as a login card. By using an individually identified card, you can log in in a more secure manner.
