Description

  The present invention relates to a service providing system using a network.

  In recent years, with the spread of network technologies such as the Internet, it has become possible to provide various services such as streaming content distribution using a network (for example, JP 2003-167785 A (see Patent Document 1)).

The following service provision forms are also possible in principle. That is, a user who operates an operation terminal connected to a network to distribute streaming content to a streaming content distribution server, receives streaming content, and displays / reproduces the streaming content on a display / speaker (hereinafter, referred to as a client). The streaming content receiving client) receives the streaming content. As a result, the user can view the streaming content via the streaming content receiving client. When the streaming content distribution server and the streaming content receiving client exist in different network areas, the user operates the operation terminal to start the network connection server that connects the two network areas, and the streaming content distribution server and the streaming content Connect the receiving client. Thus, even when the streaming content distribution server and the streaming content receiving client are in different network areas, the user can view the streaming content via the streaming content receiving client.
JP 2003-167785 A

  For example, in the provision of a service that combines the service provided by the streaming content delivery server (streaming content delivery) and the service provided by the streaming content receiving client (reception and broadcast of the streaming content) as exemplified above, a streaming content delivery server; The protocol used by the streaming content receiving client, the data format used, and the network area to which it belongs must match. If there is a mismatch, the user cannot view the streaming content (as described above, if the service can be provided by the network connection server, the network area to which the user belongs may not match).

  As described above, in order to receive a service provided by combining services provided by a plurality of service providing apparatuses (in the above example, a streaming content distribution server, a streaming content receiving client, and a network connection server), the user needs information on the service providing apparatus. (In the above example, after collecting the protocol used, the data format used, and the network area to which it belongs), each service providing device must be provided with a service. This is because service provision by each service providing device is usually paid, and each service providing device tried to provide service, but the protocol used, the data format used, If the network areas to which they belong do not match and cannot receive the service provided in combination, the service provided by each service providing device will be useless for the user and impose an economic burden on the user. Because it will be. Moreover, it must be said that it is cumbersome for the user that each service providing apparatus must start providing the service individually.

  Therefore, an object of the present invention is to eliminate the need to determine whether or not a combination is possible when a user receives a service provided by combining services provided by a plurality of service providing devices. It is to be able to receive provision of various services.

  In order to achieve the above object, in the service providing system of the present invention, a service mediating apparatus is connected to a network in addition to a plurality of service providing apparatuses and an operation terminal operated by a service user. Then, the service mediating apparatus determines whether the service can be provided by combining the services provided by the plurality of service providing apparatuses, and causes each service providing apparatus to start providing the service. Specifically, the following procedure is performed.

  First, the operation terminal transmits, to the service mediating apparatus, service providing apparatus IDs that respectively specify a plurality of service providing apparatuses selected by the service user based on the input of the service user.

  Next, upon receiving the service providing device ID from the operation terminal, the service mediating device extracts service providing device information corresponding to the received service providing device ID from the database in which the service providing device information is recorded. To do.

  Next, the service mediating apparatus determines whether or not it is possible to provide a service by combining services by a plurality of service providing apparatuses selected by the service user based on the extracted service providing apparatus information, This determination result is transmitted to the operation terminal.

  Next, when the service mediating apparatus can provide a service by combining services from a plurality of service providing apparatuses selected by the service user, the service mediating apparatus selects the service user based on the extracted service providing apparatus information. The order in which each service providing apparatus starts providing the service is determined.

  Next, when the operation terminal receives the determination result indicating that the service can be provided by combining the services provided by the plurality of service providing apparatuses selected by the service user, the operation terminal is based on the input of the service user. The service provision request is transmitted to the service mediating apparatus.

  Finally, when receiving the service provision request from the operation terminal, the service mediating apparatus causes each service providing apparatus selected by the service user to start providing the service in the above order.

  In the service providing system of the present invention, it is also possible to select one part (for example, one service providing apparatus) of the combination with the operation terminal and complete the combination with the service mediating apparatus. Specifically, the following procedure is performed.

  First, the operation terminal transmits a service providing apparatus ID for specifying the service providing apparatus selected by the service user to the service mediating apparatus based on the input of the service user.

  Next, when the service mediating device receives the service providing device ID from the operation terminal, based on this, the service providing device information corresponding to the received service providing device ID is extracted from the database in which the service providing device information is recorded. At the same time, service providing device information of other service providing devices recorded in the database is also extracted.

  Next, based on the extracted service providing device information, the service mediating device can provide the service by combining the service provided by the service user with the service provided by the service user and the service provided by another service providing device. By determining whether or not the service providing device selected by the service user is combined with the service provided by the service providing device, the service providing device combination is generated, and the generated combination result is transmitted to the operation terminal. To do.

  Next, the service mediating apparatus determines the order in which each service providing apparatus included in the combination starts providing the service based on the extracted service providing apparatus information.

  Next, when the operation terminal receives the combination result, the service terminal transmits a service provision request for the combination selected by the service user to the service mediating apparatus based on the input of the service user.

  Finally, when the service mediating apparatus receives the service provision request from the operation terminal, the service mediating apparatus causes each service providing apparatus included in the combination selected by the service user to start providing the service in the above order.

  As described above, according to the present invention, the service mediating apparatus determines whether it is possible to provide a service by combining the services provided by the service providing apparatus selected by the service user. Generated by generating a combination of service providing devices that can request service provision to the operation terminal operated by the user, or provide a service in combination with a service provided by the service providing device selected by the service user. For each combination, an operation terminal operated by a service user is requested to provide a service, so that each service providing apparatus is not allowed to provide a service unnecessarily. In addition, the service user does not need to perform a complicated operation of providing the service to each service providing device, and only operates the operation terminal and transmits a single service provision request to the service mediating device. It is possible to receive a service that is a combination of services provided by a plurality of service providing devices.

  Next, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  In the following, the best mode for carrying out the present invention will be described by taking as an example a service providing system in which service provision by a plurality of service providing apparatuses of the present invention is combined with a method called IDP (IDentity Provider) on IC chip. explain.

  IDP on IC chip is information related to the user (information such as the name, address, date of birth, etc. of the user recorded by a public institution or Internet service provider, the membership number of the Internet service provider, etc.) Information) and the right to use the purchased service (the substance is the use condition of the service recorded by the service provider) in a portable device such as an IC card or a mobile phone, and the user operates the operation terminal When the user tries to receive service from the service providing apparatus by operating the, the mobile device performs authentication processing for receiving the service provision. That is, the portable device checks whether or not the usage condition (usage right) of the service to be provided is stored in the portable device, and if it is stored, the usage stored in the portable device is also stored. The consistency with the information about the person is determined. And only when these are in agreement, a user can receive provision of a service.

  By adopting the IDP on IC chip method, it is possible to prevent information on the user from leaking from the portable device, which contributes to privacy protection. Further, as long as the user carries the portable device, the user can operate the operation terminal at the destination and receive the desired service.

(First embodiment)
A service providing system according to a first embodiment of the present invention will be described in detail with reference to the drawings. The service providing system according to the present embodiment determines whether or not the service mediating apparatus provided in the network can provide the service by combining the services provided by the service providing apparatus selected by the user. This is a system that requests an operation terminal operated by a person to provide a service.

  Referring to FIG. 1, a block diagram showing the configuration of the service providing system of the present embodiment is shown. The service providing system of the present embodiment includes an IC card 11, an operation terminal 12, a service mediating device 13, service providing devices A to F (14 to 18, 31), and a service providing device information database 40.

  The IC card 11 exchanges information with the operation terminal 12 via an IC card reader / writer provided in the operation terminal 12. The service mediating device 13, the service providing device A 14, the service providing device B 15, the service providing device C 16, the service providing device E 17, and the service providing device F 18 are connected to the network I 10. The service providing device D 31 is connected to the network II 30. The network I 10 and the network II 30 are connected to each other by the router 20. The service providing apparatus information database 40 is connected to the service mediating apparatus 13 via a network (not shown). Note that the arrangement of the network and the arrangement of the apparatus on the network are merely examples.

  The IC card 11 is a portable device carried by a user who wants to receive service. The user carrying the IC card 11 goes to the place where the operation terminal 12 is installed, and places the IC card 11 in a state where it can communicate with the IC card reader / writer provided in the operation terminal 12. The service provided by the service providing system of the embodiment can be received. As will be described in detail below, the IC card 11 uses the user information of the user who owns the IC card 11 (recorded on the IC card 11 by a public institution or Internet service provider) and the usage The right of use of the service purchased by the user (the substance is the use condition of the service recorded on the IC card 11 by the service provider) is recorded. Then, the IC card 11 determines whether or not the usage condition of the service that the user is going to receive is recorded, and then determines whether or not the user information satisfies the usage condition. Process. Thus, by performing the authentication process in the IC card 11, the user information is not leaked even to the operation terminal 12, and privacy protection can be achieved. The IC card 11 has been subjected to unauthorized rewrite prevention processing.

  The operation terminal 12 is a terminal operated by a user who places the IC card 11 in a state where it can communicate with an IC card reader / writer provided in the operation terminal 12. A user who has been successfully authenticated by the IC card 11 operates the operation terminal 12 to provide various services from the service providing apparatuses A to F (14 to 18 and 31) via the network I 10 and the network II 30. Will receive. Specifically, the user operates the operation terminal 12 to select one service providing apparatus from the service providing apparatuses available from the operation terminal 12 and receive a desired service. The service providing apparatus is combined to receive the desired service. In the service providing apparatus of the present embodiment, the focus is placed on the latter case. The next service mediating apparatus 13 determines whether or not it is possible to provide a service by combining a plurality of service providing apparatuses.

  The service mediating apparatus 13 is an apparatus that determines whether it is possible to provide a service by combining a plurality of service providing apparatuses selected by a user operating the operation terminal 12. There are various types of service providing devices. For example, there are various types of data formats of services to be provided and protocols used. Further, for example, it may be a server that distributes content, or a client that receives content and displays it. Therefore, it is necessary to determine whether or not the combination of a plurality of service providing apparatuses selected by the user operating the operation terminal 12 is appropriate. This determination is made by the service mediating apparatus 13. It is. The service mediating apparatus 13 can be connected to the service providing apparatus information database 40 in which such information relating to the service providing apparatus is stored, and the operation terminal 12 can be connected based on the information stored in the service providing apparatus information database 40. It is determined whether or not a combination of a plurality of service providing apparatuses selected by the operating user is possible.

  The service providing devices A to F (14 to 18, 31) are devices that provide various services to the user. Information regarding the service providing apparatuses A to F (14 to 18, 31) is stored in the service providing apparatus information database 40.

  Referring to Table 1, an example of service providing device information stored in the service providing device information database 40 is shown. The contents of Table 1 and the following description of the present embodiment described using the contents of Table 1 (including descriptions of the configuration and operation of each part of the service providing system of the present embodiment) are specific images. Is merely an example for promoting the understanding of the present embodiment.

  As shown in Table 1, in the service providing device information database 40, for each service providing device ID (the same as the alphabet attached to each service providing device in FIG. 1), provided service ID, used protocol, server / client The equal type, the used data format, and the area ID are stored. First, the provided service ID is an ID for identifying a service provided by the service providing apparatus. Next, the use protocol is a protocol used by the service providing apparatus (server or client). Next, the type of server / client, etc. indicates whether the service providing apparatus is a server, a client, or a network connection server, various conversion servers (protocol conversion server, server / client, etc. type conversion server, data format conversion server) ). In Table 1, the service providing devices C and D are servers that distribute content, and the service providing devices A and B receive the content distribution and display it on a display or the like (note that the service providing device A , B are arranged in the vicinity of the operation terminal 12, that is, in a position where a user operating the operation terminal 12 can see a display or the like. Protocol conversion for connecting a client to a different network when the client exists in a different network, and the service providing apparatus F converts one of the protocols to the other when the server and the client have different protocols Suppose that it is a server. Next, the use data format is a data format used by a service providing apparatus serving as a server or a client. Finally, the area ID is an ID for identifying the network to which the service providing apparatus is connected (the same as the Roman numeral assigned to each network in FIG. 1).

  Next, the configuration of each part of the service providing system according to the present embodiment will be described in detail with reference to the drawings.

  Referring to FIG. 2A, a block diagram showing the internal configuration of the IC card 11 is shown. The IC card 11 includes an authentication processing unit 111, a user information storage unit 112, and a usage condition storage unit 113.

  The authentication processing unit 111 receives a service ID for identifying a service from the operation terminal 12. Then, based on the service ID, the use condition of the service is extracted from the use condition storage unit 113. Then, authentication processing is performed to determine whether the user information stored in the user information storage unit 112 satisfies the extracted usage condition. Then, the authentication result is transmitted to the operation terminal 12.

  The user information storage unit 112 stores information about users. The user information is, for example, information such as name, address, date of birth, and information such as a membership number of an Internet service provider. Information for identifying an individual such as the former is recorded in the user information storage unit 112 by a public institution, for example. The latter information is recorded in the user information storage unit 112 by the Internet service provider or the like.

  As shown in FIG. 2B, the use condition storage unit 113 stores service use conditions for each service ID (in the example of FIG. 2B, use conditions for services a, b, d, and e are stored). ). The use conditions are, for example, conditions such as being over 18 years old (age restriction), being a member of a certain internet service provider (member restriction), and the like. When the user who owns the IC card 11 purchases the usage right to use the service, the usage conditions are recorded in the user information storage unit 112 by a company that sells the usage right of the service. (In the example of FIG. 2B, the user who owns the IC card has the right to use the services a, b, d, and e, and the usage conditions for these services are stored in the usage condition storage unit 113. )

  Referring to FIG. 3A, a block diagram showing the internal configuration of the operation terminal 12 is shown. The operation terminal 12 includes an authentication processing unit 121, a service providing device selection unit 122, a service providing device list storage unit 123, and a service provision request transmission unit 124.

  The service providing device selection unit 122 displays a list of service providing devices stored in the service providing device list storage unit 123, and selects a plurality of service providing devices from among them by user operation.

  The service providing apparatus list storage unit 123 stores a list of service providing apparatus IDs and service IDs that can be provided with services by operating the operation terminal 12. The service providing device ID and the service ID stored in the service providing device list storage unit 123 are obtained from the service providing device information database 40 via the service mediating device 13.

  Note that the service providing device selection unit 122 may display not only the service providing device list stored in the service providing device list storage unit 123 but also a private service list stored in the IC card 11. .

  The service providing device selection unit 122 transmits the service providing device ID (selection information) of the selected service providing device to the service mediating device 13. Then, a combination possible notification that is a notification that it is possible to receive the provision of the service by combining the selected service providing devices is received from the service mediating device. When the combination possible notification is received, a message to that effect is transmitted to the service provision request transmitting unit 124. In addition, the service ID of the service provided by the selected service providing apparatus is transmitted to the authentication processing unit 121.

  As shown in FIG. 3B, the service providing device selection unit 122 may be configured using, for example, a GUI (Graphical User Interface). In FIG. 3B, icons indicating each service providing device are arranged on the left side of the display screen of the operation terminal 12. The user uses the mouse to drag the desired icons and combine them. When the combination is determined, the determination button is clicked with the mouse. When the determination button is clicked, the service providing device ID (selection information) of the selected service providing device is transmitted to the service mediating device 13.

  The authentication processing unit 121 receives the service ID of the service provided by the service providing apparatus selected by the user from the service providing apparatus selecting unit 122. Then, the service ID is transmitted to the IC card 11, and the authentication result is received as a response. When the authentication result indicating that the authentication is successful is received from the IC card 11, the fact is transmitted to the service provision request transmitting unit 124.

  When the service provision request transmitting unit 124 receives the notification that the authentication is successful from the authentication processing unit 121 and the notification that the combination possible notification is received from the service providing device selection unit 122, the service provision request transmitting unit 124 provides the service mediating device 13 with the service. Send a request.

  Referring to FIG. 4A, a block diagram showing the internal configuration of the service mediating apparatus 13 is shown. The service mediating apparatus 13 includes a selection information receiving unit 131, a service providing device information acquiring unit 132, a service providing device information storing unit 133, a combination determining unit 134, an execution order determining unit 135, and a combinable notification transmitting unit 136. And a service provision request transmission unit 137.

  The selection information receiving unit 131 receives the service providing device ID of the service providing device selected by the user from the service providing device selecting unit 122 of the operation terminal 12. Then, the service providing apparatus ID is transmitted to the service providing apparatus information acquisition unit 132.

  The service providing apparatus information acquisition unit 132 searches the service providing apparatus information database 40 based on the service providing apparatus ID received from the selection information receiving unit 131, and acquires service providing apparatus information related to the service providing apparatus. Then, the acquired service providing device information is temporarily stored in the service providing device information storage unit 133.

  The service providing device information storage unit 133 temporarily stores the service providing device information acquired by the service providing device information acquisition unit 132.

  Based on the service providing device information stored in the service providing device information storage unit 133, the combination determination unit 134 determines whether or not it is possible to receive a service by combining the service providing devices selected by the user. judge.

  Referring to FIG. 4B, there is shown a flowchart for explaining the combination determination processing procedure.

  First, in step 401, it is determined whether or not the protocols used by the service providing apparatuses included in the combination (only the server and the client have a protocol) match. If they match, this step is cleared. If there are a plurality of protocols being used, this step is cleared if there is at least one common protocol even if they do not match completely. Further, if there is an appropriate protocol conversion server, this step is cleared. Of the service providing device information, the information to be determined from the protocol is the information such as the server / client type and the data format used, and the contents differ depending on the protocol. This is because the combination determination can be performed efficiently.

  Next, in step 402, it is determined whether or not the correspondence of the server / client type of the service providing apparatus is correct. If two servers or two clients are selected, the correspondence is not correct and this step is not cleared. If a server and a client, or a server, a client, a network connection server, or various conversion servers are selected, the correspondence is correct and this step is cleared. Even if two servers or two clients are selected, this step is cleared if an appropriate server / client type conversion server is included. The determination based on the server / client type rather than the used data format is information accompanying the server / client type, and the contents differ depending on the server / client type. This is because the combination determination can be performed more efficiently if the determination is made based on the type.

  Next, in step 403, it is determined whether or not the usage data format of the service providing apparatus matches (only the server and the client have the usage data format). If the usage data format matches, this step is cleared. Even if the data format used does not match, this step is cleared if an appropriate data conversion server is included.

  Finally, in step 404, whether or not the area ID of the service providing device is the same as that of the operation terminal 12 and the service mediating device 13, or a network connection server having the same area ID as that of the operating terminal 12 and the service mediating device 13 is selected. Judge whether to include. If the area ID is the same as that of the operation terminal 12 and the service mediating apparatus 13, the selected server and client can be connected to each other, and this step is cleared. Even if either of them does not have the same area ID as that of the operation terminal 12 and the service mediating apparatus 13, if the network connection server having the same area ID as that of the operating terminal 12 and the service mediating apparatus 13 exists, the selected server and the client are connected. Yes, this step is cleared.

  If the above steps are cleared, it is determined that they can be combined.

  A specific example will be described with reference to Table 1 and FIG. 2B. Assume that the user selects the service providing apparatuses A and B on the operation terminal 12 as the pattern 1. It is assumed that service providing apparatuses A and C are selected as pattern 2. It is assumed that service providing apparatuses B and C are selected as pattern 3. It is assumed that service providing apparatuses B, C, and F are selected as pattern 4. It is assumed that the service providing apparatuses B and D are selected as the pattern 5. Assume that the service providing apparatuses B, D, and E are selected as the pattern 6. Hereinafter, the determination result of each pattern will be described.

  In the pattern 1, the protocol of the service providing apparatus A is http and ftp, and the protocol of the service providing apparatus B is http. Therefore, since at least one common protocol exists, step 401 is cleared. Next, since both the service providing apparatus A (http) and the service providing apparatus B are clients, the correspondence between the types such as server / client is not correct, and step 402 is not cleared. Therefore, it is determined that the combination is impossible at this time.

  In the pattern 2, the protocol of the service providing apparatus A is http and ftp, and the protocol of the service providing apparatus C is ftp. Therefore, since at least one common protocol exists, step 401 is cleared. Next, since the service providing apparatus A (ftp) and the service providing apparatus C are a client and a server, respectively, the correspondence between server / client types is correct, and step 402 is cleared. Next, the usage data format of the service providing apparatuses A and C does not matter because the usage protocol is ftp, and step 403 is cleared. Since the area IDs of the networks to which the service providing apparatuses A and C belong are both I and coincide with the area IDs of the operation terminal 12 and the service mediating apparatus 13, step 404 is cleared. Therefore, it is determined that combination is possible.

  However, as shown in FIG. 2B, the IC card use condition storage unit 113 owned by the user has no use condition for the service c provided by the service providing apparatus C (that is, there is no use right for the service c). Therefore, the authentication by the IC card 11 ends in failure. As a result, in pattern 2, the combination itself is possible, but the service cannot be provided.

  In pattern 3, since the protocols of service providing apparatuses B and C do not match, step 401 is not cleared. Therefore, it is determined that the combination is impossible at this time.

  In pattern 4, the protocols of service providing apparatuses B and C do not match. However, since the protocol conversion server F that converts between http and ftp is selected, step 401 is cleared. Next, since the service providing apparatuses B and C are a client and a server, respectively, the correspondence between server / client types is correct, and step 402 is cleared. Next, the usage data format of the service providing apparatuses B and C does not matter because the usage protocol is ftp, and step 403 is cleared. Next, since the area ID of the network to which the service providing apparatuses B, C, and F belong is I, which matches the area IDs of the operation terminal 12 and the service mediating apparatus 13, step 404 is cleared. Therefore, it is determined that combination is possible.

  However, as shown in FIG. 2B, the IC card use condition storage unit 113 owned by the user does not have the use conditions for the services c and f provided by the service providing apparatus C (that is, the services c and f). Since there is no usage right), the authentication by the IC card 11 ends in failure. As a result, in pattern 4, the combination itself is possible, but the service cannot be provided.

  In pattern 5, since the protocols of the service providing apparatuses B and D match with http, step 401 is cleared. Next, since the service providing apparatuses B and D are a client and a server, respectively, the correspondence between the types such as server / client is correct, and step 402 is cleared. Next, since the usage data formats of the service providing apparatuses B and D are both application / pdf, the data formats match and step 403 is cleared. Next, the area IDs of the networks to which the service providing apparatuses B and D belong are I and II, respectively, and the area ID of the service providing apparatus D does not match I which is the area ID of the operation terminal 12 and the service mediating apparatus 13. Since no network connection server with area ID I is selected, step 404 is not cleared. Therefore, it is determined that the combination is impossible at this time. Incidentally, in this case, at least a network connection server whose area ID is I (that is, connected to the network I) is required.

  In pattern 6, since the protocols of the service providing apparatuses B and D match with http, step 401 is cleared. Next, since the service providing apparatuses B, D, and E are a client, a server, and a network connection server, respectively, the correspondence between the types such as server / client is correct, and step 402 is cleared. Next, since the usage data formats of the service providing apparatuses B (client) and D (server) are both application / pdf, the data formats match and step 403 is cleared. Next, the area IDs of the networks to which the service providing apparatuses B, D, and E belong are I, II, and I, respectively, and the area ID of the service providing apparatus D is the area ID of the operation terminal 12 and the service mediating apparatus 13. Does not match. However, since the network connection server E whose area ID is I is included, step 404 is cleared. Therefore, it is determined that combination is possible.

  In pattern 6, as shown in FIG. 2B, since there is a right to use services b, d, and e provided by service providing apparatuses B, D, and E, the user provides service providing apparatuses B, D, and E. A service combining services b, d, and e can be provided.

  When the combination determining unit 134 determines that the combinations can be performed, the execution order determining unit 135 determines the execution order of the service providing devices based on the service providing device information stored in the service providing device information storing unit 133.

  Referring to FIG. 4C, a flowchart showing a procedure for determining the service provision start order of the service provision apparatus is shown. First, in step 411, service provision is started to the network connection server or various conversion servers that mediate between the server and the client. Next, since the server must receive a request from the client, in step 412, the service is started before the client. Finally, in step 413, the service is started by the client.

  The combination possible notification transmission unit 136 transmits a combination possible notification to the operation terminal 12 when the combination determination unit 134 determines that combination is possible.

  The service provision request transmission unit 137 receives the service provision request transmitted by the operation terminal 12 in response to the combination possible notification, and transmits the service provision request to each service provision apparatus in the order determined by the execution order determination unit 135.

  Finally, the operation of the service providing system of this embodiment will be described in detail with reference to the drawings.

  As the operation of the service providing system of the present embodiment, for example, the following three types of operations can be considered. In the first operation, first, the combination determination is performed by the service mediating apparatus 13, and when the combination is possible, the authentication processing by the IC card 11 is performed. According to the first operation, the authentication process is performed only for the service provided by the service providing apparatus that can be combined, so that useless authentication process can be omitted. The second operation is that when the user selects a service providing device using the operation terminal 12, the service provided by the selected service providing device is authenticated by the IC card 11, and only when the authentication is successful, the service mediation is performed. The combination determination by the device 13 is performed.
