Description

[Technical field]

[0001] The present disclosure relates to a program, a method, and an information processing device. [Background technology]

[0002] As a sales promotion measure, businesses develop campaigns, accept applications from consumers, and offer prizes and other benefits. This is expected to increase awareness of products, etc.

[0003] There are various methods for such campaigns. For example, some campaigns require consumers to provide a photograph of the receipt for the purchase of the product taken with a mobile terminal or the like in order to apply for the campaign on the condition that the consumer purchases the product. For example, a special benefit may be offered to a consumer who provides a receipt for the purchase of a product sold at a convenience store or a receipt showing that a specific menu item was ordered at a restaurant.

[0004] Applications for campaigns may include those made by consumers who do not meet the application conditions. For example, when consumers provide photographs of receipts, fraudulent applications may be made by using duplicate receipts or by modifying the photographs. In this case, if a benefit is awarded to a consumer for a fraudulent application, it may create a sense of unfairness between the consumer and a legitimate applicant.

[0005] Patent Document 1 describes a technology that aims to "prevent fraudulent campaign applications using receipts that do not actually involve purchases." Specifically, Patent Document 1 describes how "when a campaign application is made from a mobile terminal to a campaign server based on an issued product receipt, the campaign application is authenticated," and how "time information presented by a time information display device installed in a store and read by a mobile terminal when the product is checked out is acquired as the product purchase time," how "receipt information including the receipt time is read from a product receipt image taken by a mobile terminal after the product checkout process," how "the purchase time and receipt time are compared to determine whether the time difference is within a predetermined range," and how "if the time difference is determined to be within the predetermined range, the receipt information is considered valid and the campaign application is permitted."

[0006] According to the technology in Patent Document 1, this is said to have the effect of "preventing fraudulent campaign applications using receipts for which no actual purchasing action has been taken." [Prior art documents] [Patent documents]

[0007] [Patent Document 1] JP 2018-101189 A Summary of the Invention [Problem to be solved by the invention]

[0008] If fraudulent entries into a campaign are detected, it may be considered undesirable to award a reward for that entry, as described above.

[0009] On the other hand, campaigns aimed at consumers are expected to be a marketing measure to encourage trial use of the product, etc. For this reason, campaigns may be carried out over a certain period of time, such as one month.

[0010] One purpose of a campaign may be to raise awareness of a product or the like and to encourage actual use. Therefore, even if fraud is detected in a consumer's application to a campaign, if no benefits are given to the consumer during the campaign period, which is carried out over a certain period of time as described above, this may reduce consumer motivation to participate in the campaign, and may result in the marketing objective being lost.

[0011] Therefore, there is a need for technology that can increase the likelihood of achieving the campaign's objectives while preventing consumers from feeling that the campaign is unfair when applying for the campaign and without reducing their motivation to participate in the campaign. [Means for solving the problem]

[0012] According to an embodiment of the present disclosure, a program for operating a computer including a computer processor is provided. The program causes the computer processor to execute the steps of accepting an application for a campaign from a user, determining whether the application for the campaign is fraudulent, granting the right to participate in a lottery to the user in response to the application for the campaign even if the application is determined to be fraudulent, accepting an operation to perform a lottery process by consuming the granted right to participate in the lottery from the user, performing the lottery process in response to the operation to perform the lottery process, and presenting the result of the lottery process to the user. In the step of performing the lottery process, if the user has the right granted by the fraudulent application for the campaign, the user is not eligible for the lottery process even if the operation to perform the lottery process is accepted, and even if the user was not eligible for the lottery process, the user is restored to be eligible for the lottery process by satisfying a certain condition. Effect of the Invention

[0013] According to the present disclosure, it is possible to further increase the likelihood of achieving the campaign objectives while avoiding any sense of unfairness among consumers when applying for a campaign and without reducing their motivation to participate in the campaign.

[0117] Specifically, the item “prize ID” corresponds to the item “prize ID” in the campaign prize database 212.

[0118] The item "lottery date and time" is information indicating the timing at which a user operation for obtaining a special benefit was accepted.

[0119] Specifically, the item "lottery date and time" includes information on the timing at which an operation to perform a lottery process was accepted as a user operation for obtaining a benefit.

[0120] The item "Winning result" is information indicating whether or not the user received a special benefit.

[0121] Specifically, the item "Winning Results" includes the following information: Winning (winning) Did not win (loser) <3 operations> FIG. 8 is a diagram showing the flow of a process for accepting an application for a campaign from a user.

[0122] In step S811, the terminal 10 accepts an operation to upload a captured image of a receipt as an entry for the campaign from the user, whereby the server 20 accepts the entry for the campaign from the user.

[0123] In step S821, the application acceptance module 2044 of the server 20 receives the photographed image of the receipt, thereby accepting an application for the campaign from the user, and updates the campaign application database 213.

[0124] In response to an application for the campaign, the application acceptance module 2044 grants the user a number of points corresponding to the application as a right to participate in a lottery, and updates the user database 211.

[0125] The number of rights to participate in a lottery granted as a result of a fraudulent application is also managed in the user database 211. Even if an application is determined to be fraudulent, the application acceptance module 2044 grants the user the number of points corresponding to the application, updates the item "total points" in the user database 211, and presents information on the points granted to the user (the amount of points the user acquired through the application, the total amount of points the user possesses) to the user through the process described below.

[0126] Each time an application for a campaign is received from a user, the application acceptance module 2044 updates the user database 211 by increasing the number of points held by the user by associating quantity information (point information) indicating the right to participate in a lottery with the user.

[0127] In step S823, the fraud determination module 2045 of the server 20 performs optical character recognition processing on the photographed image of the receipt. The fraud determination module 2045 sends the photographed image of the receipt to the OCR service server 40, receives the results of reading the characters contained in the photographed image of the receipt from the OCR service server 40, and updates the campaign application database 213.

[0128] The fraud determination module 2045 determines whether the campaign application conditions are met from the read characters. For example, the following computer processing may be used to determine whether the campaign application conditions are met. Note that multiple campaign application conditions such as those below may be combined. If a condition for entering the campaign is to purchase at a specific store (such as a chain store), the store where the purchase was made is identified from the phone number read, and a determination is made as to whether the condition for entering the campaign is met. If the condition for entering the campaign is to purchase a specific product (or to purchase a certain number of items), the product name is scanned to determine whether a specific product has been purchased (a certain number of items has been purchased), and a determination is made as to whether the condition for entering the campaign is met. If the condition for entering the campaign is to purchase more than a certain amount, the total amount read will be used to determine whether the condition for entering the campaign is met.

[0129] In step S825, the fraud determination module 2045 of the server 20 determines whether the campaign application is fraudulent. Specifically, the fraud determination module 2045 presents the operator with a photographed image of the receipt and the results of the optical character recognition processing, accepts the operator's designation as to whether the application was made using a fraudulent receipt, and updates the campaign application database 213.

[0130] The fraud determination module 2045 may present to the operator user, together with the photographed image of the receipt, character information read from the photographed image of the receipt by optical character recognition processing. The fraud determination module 2045 may present to the operator the result of determining whether or not the application conditions for the campaign are met by the optical character recognition processing in the processing of step S823.

[0131] In step S827, if an application for a fraudulent receipt is specified, the server 20 refers to the user database 211 and updates the error determination points.

[0132] FIG. 9 is a diagram showing the flow of the lottery process.

[0133] In step S921, the lottery processing module 2046 of the server 20 presents the user with a screen for drawing prizes as a campaign benefit.

[0134] In step S911, the terminal 10 displays the total amount of points acquired by the user (total number of points) and accepts an operation to draw prizes for the campaign. The terminal 10 accepts an operation from the user to perform a lottery process by consuming the right (points) to participate in the lottery granted to the user.

[0135] In step S923, the lottery processing module 2046 of the server 20 refers to the user database 211, and if the user has rights that were granted by applying for a fraudulent campaign, the lottery processing module 2046 will not treat the user as an eligible candidate for the lottery processing even if it accepts an operation to perform the lottery processing, and even if the user was previously ineligible for the lottery processing, the lottery processing module 2046 will restore the user to be eligible for the lottery processing by satisfying certain conditions.

[0136] Specifically, if there are remaining error judgment points, the lottery processing module 2046 consumes the points required for the lottery from the error judgment points and determines the lottery result as "not winning." If there are no remaining error judgment points, the lottery processing module 2046 performs the lottery processing while consuming the points required for the lottery. Note that the lottery processing module 2046 consumes the amount of points required for the lottery from the total number of points.

[0137] In the step of performing the lottery processing, the lottery processing module 2046 performs the lottery processing by consuming the right to participate in the lottery in a quantity corresponding to the operation for performing the lottery processing, and updates the lottery history database 214.

[0138] As described above, the lottery processing module 2046 refers to the user database 211 and presents to the user the total number (total number of points) of the first number awarded for a non-fraudulent application and the second number awarded for a fraudulent application as the number of rights to participate in the lottery that the user holds, but does not present the second number (error determination points) of the rights to participate in the lottery that was awarded due to a fraudulent application.

[0139] In the step of processing the lottery, in response to receiving an operation to perform the lottery from a user, the lottery is processed by consuming the second quantity first, by an amount corresponding to the lottery, and if the second quantity is present at the stage of receiving the operation to perform the lottery, the lottery is not eligible for winning, and if the second quantity is absent at the stage of receiving the operation to perform the lottery, the lottery is eligible for winning. The lottery processing module 2046 may restore the lottery to be eligible for winning by satisfying a certain condition, and may include consuming the second quantity completely by receiving the operation to perform the lottery and performing the lottery to reach a state where there is no second quantity.

[0140] In step S925, the server 20 presents the result of the lottery process to the user.

[0141] In step S913, the terminal 10 displays the result of the lottery process.

[0142] <4 Screen example> FIG. 10 shows an example of a user operation screen.

[0143] The operation screen 1000 is a screen that accepts operations from users, who are consumers, for applying to a campaign and obtaining campaign benefits.

[0145] The user information display area 1002 may display the following information as information about the logged-in user: If the Service accepts login via a user's SNS account, that SNS account -Login ID issued by Server 20 The campaign information display area 1004 is an area for displaying detailed information about the campaign.

[0146] The campaign information display area 1004 may display the following as detailed information about the campaign: Campaign name, advertiser Campaign period The number of points that the user has earned by applying for the campaign as the right to participate in the lottery (item "Total points" in user database 211) · Number of times a user applied for a campaign (number of times a user uploaded a photo of a receipt and earned points) The switching operation receiving unit 1006 is an operating member that receives an operation to switch the campaign for which details are to be displayed.

[0147] The application summary display area 1008 is an area that displays a summary of the conditions for applying to the campaign.

[0148] The application summary display area 1008 displays, for example, a summary of the application for the following campaign and accepts applications for the campaign from the user. -Upload a receipt for the product that is eligible for the campaign The condition details display area 1010 is an area for displaying details of the application conditions for the campaign.

[0149] The condition details display area 1010 displays details of the campaign entry conditions, for example, as follows: - Purchasing a product is a condition for entering the campaign. Uploading the receipt for that purchase is a condition for entry. · Purchasing products from a specific group of stores Purchasing a specific product -Purchase the product within the specified period The upload operation receiving section 1012 is an operation member that receives an operation for applying to a campaign from a user.

[0150] The upload operation receiving unit 1012 displays the following contents as the operation contents required by the user to apply for the campaign. Taking a picture of the receipt when purchasing a product and uploading the taken picture. The camera may be started in response to an operation on the upload operation reception unit 1012, and an image file may be selected. The reward list display area 1014 is an area that displays a list of rewards provided in the campaign.

[0151] As shown in the figure, the benefit list display area 1014 may display a plurality of types of benefits and the conditions for obtaining each benefit (such as the number of rights to participate in a lottery to be consumed).

[0152] The first award name display area 1016 is an area for displaying details of the first award when multiple awards are provided.

[0153] As shown in the figure, the first bonus name display area 1016 may display information on the content of the bonus, the number of bonuses to be distributed, and the remaining number, based on the campaign prize database 212.

[0154] The first lottery operation receiving unit 1018 is an operating member that receives an operation for obtaining a special benefit from a user.

[0155] As shown in the figure, the first lottery operation acceptance unit 1018 may display that whether or not a special benefit is obtained is determined by a lottery, and the number of points required for the lottery.

[0156] The second award name display area 1020 is an area for displaying details of the second award when multiple awards are provided.

[0157] As shown in the figure, the second bonus name display area 1020 may display the content of the bonus, the number of bonuses to be distributed, and the remaining number of bonuses based on the campaign prize database 212. As shown in the figure, it is displayed that the second bonus has different points and the number of bonuses to be distributed compared to the first bonus.

[0158] The second lottery operation receiving unit 1022 is an operating member that receives an operation for obtaining a special benefit from a user.

[0159] As shown in the figure, the second lottery operation receiving unit 1022 may display that whether or not a special benefit is obtained is determined by a lottery and the number of points required for the lottery. The second lottery is displayed as having a different number of points required for the lottery compared to the first lottery.

[0160] FIG. 11 is an example of a screen that displays the lottery result in response to the lottery process.

[0161] FIG. 12 is an example of a screen that displays the lottery result in response to the lottery process.

[0162] The lottery result display area 1024 is an area where the result of the lottery process is displayed.

[0163] In the example of Fig. 11, the lottery result display area 1024 indicates that the server 20 accepts an operation to perform a lottery process for the second benefit (second benefit name display area 1020) from the user (second lottery operation acceptance unit 1022), but has determined that the user will not win because the user has remaining error judgment points (item "error judgment points" in the user database 211) (step S923 in Fig. 9). As shown in Fig. 11, the screen presented to the user displays the result that the user did not win the lottery process. As shown in the figure, the error judgment points are not presented to the user, and the fact that the user has remaining error judgment points is not presented to the user.

[0164] The award detail display area 1026 is an area that displays details of the award for which the user has performed an operation to obtain the award.

[0165] 11, the benefit details display area 1026 indicates that the user has performed a lottery process for the second benefit (second benefit name display area 1020). As a result of the operation of this lottery process (second lottery operation acceptance section 1022), the campaign information display area 1004 indicates that the number of points owned by the user has been subtracted by the amount required for the lottery process (the "total points" item in the user database 211). Also, as a result of the operation of the lottery process, the number of error judgment points is assumed to be consumed by the amount required for the lottery process and become zero.

[0166] Assume that the user performs a lottery process (first lottery operation receiving unit 1018) for the first benefit (first benefit name display area 1016) from the state of FIG. 11, resulting in the state of FIG. 12. As described above, since the error determination points are zero, if the lottery process is performed, the user may win the benefit (step S923). In FIG. 12, as a result of winning the first benefit, the lottery result display area 1024 displays that the user has won the lottery. Also, the benefit details display area 1026 displays that the remaining number of benefits has decreased as a result of winning the first benefit (item "number of remaining benefits" in the campaign gift database 212). Also, the campaign information display area 1004 displays that the number of points the user has has been reduced by the amount required for the lottery process.

[0167] The history viewing operation acceptance unit 1028 is an operation member that accepts an operation for viewing the results of lottery processes that the user has performed in the past.

[0168] <Modification> In addition to the aspects described in the above embodiment, the following may be adopted: The following will describe the chronological experience of a user after the user starts using the service.

[0169] (1) Number of bonuses distributed and remaining In the above embodiment, the number of benefits provided is limited, as shown in the example of Fig. 5. Alternatively, the number of benefits provided may not be limited, and may be provided to the user as many times as the user wins the lottery.

[0170] (2) Management of points earned by users In the above embodiment, the user database 211 manages the total number of points acquired by a user's application to a campaign that is free of fraud and the total number of points acquired by an application that is determined to be fraudulent, under the item "total points". In addition, points acquired by an application that is free of fraud and points acquired by an application that is determined to be fraudulent may be managed separately as described above. The total number of points acquired by an application that is free of fraud and the total number of points acquired by an application that is determined to be fraudulent is presented to the user. Note that, by performing the lottery process, points acquired by an application that is free of fraud are subtracted first, but there are cases where the number of points required for the lottery is greater than the number of error judgment points (for example, the number of error judgment points of the user is 10 points, and the number of points required for the lottery is 30 points). In this case, the difference between the points required for the lottery and the number of error judgment points may be subtracted from the points acquired by an application that is free of fraud, in accordance with the lottery process. In this way, the number of points presented to the user can be presented as if the points consumed in the lottery process have been subtracted.

[0171] (3) Lottery process when a user has an error judgment point In the above embodiment, when the user has an error judgment point number, the server 20 determines that the user will not win even if the user performs a lottery process to obtain a special benefit. In this case, the server 20 may not execute the lottery process itself. At this time, the server 20 may display a standby screen on the user's terminal 10 indicating that the lottery process is being performed (displaying "lottery in progress" or the like on the screen), but may not execute the lottery as a process, and may return a message to the user's terminal 10 after a predetermined time that the user did not win. This can reduce the use of the server 20's computer processing resources for the lottery process.
