Once the purchase procedure is completed, the purchase information is sent to the market server 200 and registered as a purchase history. This is the sequence of events that occurs when purchasing a ticket.

[0059] Next, specific processing of the information terminal, market server, and member server will be described with reference to Fig. 9. As shown in Fig. 9, first, a purchase process is started by the information terminal 100 in response to an operation by a user who wishes to purchase tickets on the information terminal 100. The purchase process is a process for applying for and purchasing tickets that members can purchase preferentially. When the purchase process is started, the control unit 120 makes a purchase application using the function of the purchase application sending unit 121 (step S11) and transmits a purchase application request to the market server 200. Specifically, in the processing of step S11, the purchase application sending unit 121 makes a purchase application to the market server 200 based on the purchase application operation by the user who wishes to purchase tickets, and transmits the purchase application request to the market server 200.

[0060] When the market server 200 receives a purchase application request from the information terminal 100, it starts the purchase management process. The purchase management process is a process for managing purchase data, including generating a purchase page and managing the purchase rights used by the prospective purchaser. When the purchase management process starts, the control unit 220 instructs the information terminal 100, which is the sender of the purchase application request, to log in to the member server 300 using the function of the login instruction unit 221 (step S12). Specifically, in the process of step S12, the login instruction unit 221 instructs the information terminal 100, which is the sender of the purchase application request, to log in to the member server 300 by sending a login page to the member server 300.

[0061] A login screen for the member server 300 is displayed on the information terminal 100. When the user who wishes to purchase logs in to the member server 300, the control unit 120 uses the function of the login request unit 122 to send login information to the member server 300 (step S13). Specifically, in the processing of step S13, the login request unit 122 requests the user who wishes to purchase to log in to the member server 300 by sending the input login information to the member server 300 based on the operation of the input / output unit 130 by the user.

[0062] When the member server 300 receives the login information from the information terminal 100, it starts the purchase right identification process. The purchase right identification process is a process that authenticates the user who wishes to purchase, identifies the purchase right owned by the user, hashes the user's member ID, and so on. When the purchase right identification process starts, the control unit 320 performs login authentication using the function of the login authentication unit 321 (step S14). Specifically, in the process of step S14, the login authentication unit 321 authenticates the user by determining whether the member ID and password included in the user's login information received from the information terminal 100 match the registered contents of the member information 312.

[0063] After executing the process of step S14, the control unit 320 determines whether the authentication is successful or not using the function of the login authentication unit 321 (step S15), and if the authentication is unsuccessful (step S15; No), ends the purchase right identification process. If the authentication is unsuccessful, the information terminal 100 and the market server 200 are notified of this fact, and the purchase process and purchase management process are ended.

[0064] On the other hand, if it is determined in the processing of step S15 that the authentication is successful (step S15; Yes), the control unit 320 uses the function of the purchase right identification unit 322 to identify the purchase rights owned by the member who successfully logged in (step S16). Specifically, in the processing of step S16, the purchase right identification unit 322 identifies the purchase rights owned by the user who is the intended purchaser and whose login authentication was successful in the processing of step S15, i.e., the fan club member, by referring to the member information 312. For example, if a member with the member ID "3r4my@siort.co.jp" shown in FIG. 7 logs in, the purchase right identification unit 322 in the processing of step S16 identifies that the member owns "Purchase Right 1" and "Purchase Right 2."

[0065] 9, after executing the processing of step S16, control unit 320 hashes the member ID of the member who successfully logged in using the function of member ID hashing unit 323 (step S17). Specifically, in the processing of step S17, member ID hashing unit 323 hashes the member ID of the member who successfully logged in and was authenticated in the processing of step S15 using a preset hash function to generate a member ID hash value.

[0066] After executing the process of step S17, the control unit 320 uses the function of the member information providing unit 324 to provide the member information to the market server 200 (step S18), and ends the purchase right identification process. Specifically, in the process of step S18, the member information providing unit 324 provides the market server 200 with member information including a member ID hash value corresponding to the user (member) who wishes to purchase and purchase right information owned by the user (member) who wishes to purchase. For example, when a member with the member ID "3r4my@siort.co.jp" shown in FIG. 7 logs in, in the process of step S18, the hash value of the member ID "3r4my@siort.co.jp" and purchase right information indicating that the member owns "Purchase Right 1" and "Purchase Right 2" are provided to the market server 200 as member information.

[0067] On the market server 200 side, when the member information is received from the member server 300, the control unit 220 acquires information on the purchase right owned by the intended purchaser using the function of the purchase right acquisition unit 222 (step S19). Specifically, in the processing of step S19, the purchase right acquisition unit 222 checks the purchase right information included in the member information received from the member server 300, thereby acquiring information on the purchase right owned by the user who is the intended purchaser.

[0068] After executing the process of step S19, the control unit 220 uses the function of the purchase right extraction unit 223 to extract purchase rights that can be used to purchase the desired ticket from the owned purchase rights indicated by the purchase right information acquired in the process of step S18 (step S20). Specifically, in the process of step S20, the purchase right extraction unit 223 extracts information on usable purchase rights from the owned purchase rights indicated by the purchase right information acquired in the process of step S18, based on the purchase right correspondence information 212 and the purchase history information 213. For example, if the desired ticket is "Ticket C" and the process of step S19 identifies that "Purchase Right 1" and "Purchase Right 2" are owned, in the process of step S20, the purchase right extraction unit 223 checks the purchase right correspondence information 212 and the purchase history information 213 to determine whether the upper limit number of purchases has already been made using the owned purchase rights. If the upper limit of purchases has already been made using the purchase right currently owned, the purchase right is deemed to be an unusable purchase right, and the purchase right extraction unit 223 extracts purchase rights other than that purchase right as usable purchase rights. Note that, as shown in Figure 4, the purchase rights that can be used for "Ticket C" are purchase rights 1 to 4. Therefore, for example, if a user owns "Purchase Right 1," "Purchase Right 2," and "Purchase Right 5," and assuming that none of the tickets have been used yet, when the processing of step S20 is executed, "Purchase Right 1" and "Purchase Right 2" will be extracted.

[0069] After executing the process of step S20, the control unit 220 generates a purchase page using the function of the purchase page generation unit 224 (step S21). Specifically, in the process of step S21, the purchase page generation unit 224 generates a purchase page for carrying out the purchase procedure by prompting the user to select which of the available purchase rights extracted in the process of step S20 to use for the purchase, as shown in FIG. 10. As shown in the figure, the purchase page includes the purchase quantity, price, and a purchase button. Note that in the process of step S21, a purchase impossible page may be generated indicating that the ticket purchase is impossible, for example, if a notification that login authentication failed is received in the process of step S15 or if a notification that a cancellation has been made is received from the information terminal 100.

[0070] After executing the processing of step S21, the control unit 220 uses the function of the purchase page provider 225 to provide the purchase page generated in the processing of step S21 to the information terminal 100 (step S22). Specifically, in the processing of step S22, the purchase page provider 225 provides the purchase page generated in the processing of step S21 to the information terminal 100, which is the sender of the purchase application request. As a result, the purchase page is displayed on the information terminal 100, as shown in FIG.

[0071] On the information terminal 100 side, when the user operates the displayed purchase page, specifically, selects the purchase right to be used, selects the purchase quantity, and taps the purchase button, the control unit 120, using the function of the purchase right selection sending unit 124, sends purchase information to the market server 200 (step S23), and ends the purchase process. Specifically, in the process of step S23, the purchase right selection sending unit 124 sends purchase information to the market server 200, including various information such as the purchaser ID, the member ID hash value, purchase item information, the purchase quantity, and the purchase right to be used. By performing the process of step S23, the purchase procedure is carried out. Note that in this embodiment, a description of the payment process is omitted; however, for example, a payment method such as a credit card or debit card may be selected on the purchase page, and an existing payment process may be carried out.

[0072] On the market server 200 side, when the purchase information is received, the various information included in the purchase information is registered in the purchase history registration unit 226 (step S24), and the purchase management process is terminated. Specifically, in the process of step S24, the purchase history registration unit 226 registers the purchase right selected on the purchase page as a usage purchase right, and various information such as the purchaser ID, member ID hash value, purchase item information, purchase quantity, and usage purchase right in the purchase history information 213, as shown in FIG. 5. For example, as shown in FIG. 10, if one ticket C is purchased using purchase right 2 (purchaser ID "amniuoiuk", member ID hash value "382659"), the process of step S24 is executed, and the information in the last line shown in FIG. 5 is registered.

[0073] The above is the operation of the information terminal 100, market server 200, and member server 300. As described above, with the purchase management system 1 according to this embodiment, if a potential purchaser is a member of multiple fan clubs, the potential purchaser can select which of the multiple purchase rights he or she owns to use to purchase tickets, thereby improving convenience for the potential purchaser. Furthermore, the market server 200 according to this embodiment stores and manages information on used purchase rights as purchase history information 213. Therefore, since all purchase rights of the potential purchaser can be confirmed on the market server 200 side, when making subsequent purchases using different purchase rights, there is no need to log in to the member server 300 again, thereby improving convenience. Furthermore, with the purchase management system 1 according to this embodiment, the market server 200 uses a hash value of the member ID, thereby keeping the potential purchaser's member ID confidential and ensuring security. Furthermore, by checking the hash value of the member ID included in the purchase information, the market server 200 can detect duplicate purchases by the same member ID.

[0074] (Variation) The present invention is not limited to the above-described embodiment, and various modifications and applications are possible. For example, the information terminal 100, market server 200, and member server 300 according to the above-described embodiment do not necessarily have all of the technical features described above, but may have some of the configurations described in the above-described embodiment so as to solve at least one problem in the prior art. Furthermore, at least a portion of each of the following modifications may be combined.

[0075] In the above embodiment, in the processing of step S21 shown in Fig. 9, the market server 200 generates a purchase page for carrying out the purchase procedure by having the user select which purchase right to use. However, this is just one example. Before the processing of step S21, for example, as shown in Fig. 11, a use purchase right selection form for selecting a use purchase right may be generated and provided to the information terminal 100, so that the prospective purchaser can select in advance the purchase right to use. Then, in the processing of step S21 shown in Fig. 9, a purchase page for making a purchase using the purchase right selected in the form, such as the purchase page shown in Fig. 12, may be generated.

[0076] In the above embodiment, the purchase history is stored as purchase history information 213, and information on used purchase rights is managed by the market server 200. However, this is merely an example. The management of used purchase rights may be performed by the member server 300. That is, the purchase history information 213 may be stored in the member server 300. In this case, the market server 200 does not execute the process of step S24 shown in FIG. 9, but instead transmits the purchase information received from the information terminal 100 to the member server 300, and the member server 300 executes a process similar to the process of step S24. In this case, after identifying the purchase rights owned by the member who successfully logged in in the process of step S16 shown in FIG. 9, only the purchase rights that can be used for the ticket desired to be purchased may be extracted and provided to the market server 200 in the process of step S18. For example, if the processing in step S16 identifies that a certain member owns "Purchase Right 1," "Purchase Right 2," and "Purchase Right 5," and the ticket the member wishes to purchase is "Ticket C," information on "Purchase Right 1" and "Purchase Right 2" can be extracted and provided as member information in the processing in step S18. This means that if the member subsequently purchases another product, they will need to log in to the member server 300 again, but privacy can be protected.

[0077] In the above embodiment, as shown in FIG. 5, various information is stored in the market server 200 as the purchase history information 213, but this is merely an example. The purchase history information 213 may include, for example, information on unused purchase rights. In other words, the purchase history information 213 may include information on purchase rights that are owned by the user who intends to purchase but have not yet been used. In this way, once the purchase rights owned by the user who intends to purchase are acquired, the market server 200 can keep track of their usage status, so that when the user subsequently purchases another product, there is no need to log in to the member server 300 again, thereby improving convenience.

[0078] The information terminal 100, market server 200, and member server 300 according to the above-described embodiments can be realized using a normal computer, rather than using dedicated devices. For example, the information terminal 100 that executes the above-described processes may be configured by installing a program for executing any of the above processes on a computer from a recording medium that stores the program. Also, a single information terminal 100, market server 200, and member server 300 may be configured by multiple computers operating in cooperation with each other.

[0079] Furthermore, when the above-mentioned functions are realized by sharing the functions between an OS (Operating System) and an application, or by cooperation between the OS and the application, only the parts other than the OS may be stored on the medium.

[0080] It is also possible to superimpose the program on a carrier wave and distribute it via a communication network. For example, the program may be posted on a bulletin board system (BBS) on the communication network and distributed via the network. These programs may then be started and run under the control of an operating system in the same way as other application programs, thereby enabling the above-mentioned processing to be performed.
