  When a new service is added to the authenticated user in addition to the service provided by the existing service providing system, it is considered that the service providing system can manage all the additional systems for providing the additional service. It is done. However, such a configuration places a heavy burden on the service providing system, such as major modifications to existing programs and the operation and management of new additional systems. In particular, the amount and type of information on additional services is enormous. In some cases, the cost and effort for adding the service is enormous. When the burden on the service providing system becomes enormous in this way, for example, when a company different from the operating company of the existing service providing system is provided, it becomes difficult to spread the additional service. As a result, the service type in the existing service providing system is fixed, and the expandability is impaired.

  Therefore, the present invention provides a service expansion system and a linkage server that can expand the range of types of services provided by an existing service providing system to a user without imposing a burden on the existing service providing system. Objective.

  The present invention solves the above-described problems by the following means. In order to facilitate understanding of the present invention, reference numerals in the accompanying drawings are appended in parentheses, but the present invention is not limited to the illustrated embodiment.

The service expansion system (1, 1 ′) of the present invention includes an operation input unit (23) that receives a user operation, a user terminal (2) that includes an output unit (22) that outputs predetermined information, and the user A service providing server (3) that performs authentication processing of a user who operates the terminal, permits access to the user terminal of the user who has been authenticated by the authentication processing, and provides a predetermined service in response to a request from the user terminal; An extended providing system (4) for providing an extended service to a user of the user terminal permitted to access, wherein the service providing server includes a user terminal that permits the access. When the usage information request is acquired, the source information indicating that the usage information is transmitted from the service providing server and the usage information are issued. Moistened with calling time information in the utilization information, the a use information transmission unit that transmits to the user terminal (30a), said expansion providing system, an associated server (89 extended service providing server (5) The linkage server acquires the usage information from the user terminal, confirms from the source information that the source of the usage information is the service providing server, and the transmission time information. Based on the usage confirmation unit (80a ) that performs a usage confirmation process for confirming that the access is permitted to the user terminal, and when the confirmation in the usage confirmation process is performed , the user terminal and an extension information generating unit (80b) that generates and transmits extension information for access to the enhanced service providing server is permitted to the user terminal, the expansion When the service providing server acquires the extended information from the user terminal, the service providing server includes an extended service providing unit (50b) that permits access from the user terminal and starts providing information related to the extended service to the user terminal. and, pre-SL user terminal in a state in which the access is permitted, when a predetermined operation by the user, usage information requesting unit (20a to transmit the usage information request for requesting the usage information to the service providing server ), And when the usage information is acquired from the service providing server, the usage information transfer unit (20b) transfers the usage information to a server including the usage confirmation unit of the extended providing system, and the extended information from the linkage server When acquiring the extension information transmitting unit (20c) for transmitting the extension information to the extension service providing server; An output corresponding to information relating to the extension service provided by the extension service providing server, enhanced services corresponding unit for performing at said output section and (20f), by having, to solve the above problem.

  According to the service extension system of the present invention, the usage information request unit of the user terminal is allowed to acquire usage information including transmission source information and transmission time information from a service providing server that permits access to an authenticated user, and further acquires the usage information. The usage information is transmitted to a server having a usage confirmation unit of the extended provision system. In the usage confirmation unit, it is determined whether the user of the user terminal is permitted to access the service providing server based on the transmission source information and the transmission time information included in the usage information. Based on the transmission time information of the usage information, the transmission time at which the usage information is transmitted is specified. For example, if the difference between the transmission time and the current time is small, it can be considered that the user terminal is still allowed to access. . In addition, since the usage confirmation unit acquires the usage information from the user terminal, it can be confirmed from the source information that the usage information has been transmitted from the service providing server. When it is confirmed that the access is permitted, the extended access providing unit provides information related to the extended service to the user terminal.

  The user terminal permitted to access the service providing server is a user terminal using the service providing server. According to the present invention, the extended service is provided to the user using the service providing server. be able to. Therefore, since the user is provided with the extended service only by receiving authentication of the existing service providing server, it can be seen as if the range of types of services provided by the existing service providing server has been expanded. Further, the usage confirmation unit can confirm the source of the usage information acquired from the user terminal based on the source information. Furthermore, since the usage confirmation unit is configured to be able to acquire usage information not through the service providing server but through the user terminal, the service providing server may permit access to the user terminal through a normal procedure, It is only necessary to transmit the usage information including the transmission time and the transmission source information in response to a request from the user terminal. Accordingly, it is possible to expand the range of types of services provided to the user by the existing service providing system without imposing a burden on the existing service providing system.

  The transmission time information includes a case of the transmission time itself, a symbol or character indicating the transmission time, and a time zone to which the transmission time belongs. When the outgoing time information is a time zone, for example, the usage confirmation unit determines whether the current access is permitted by comparing the time zone to which the current time belongs and the time zone to which the outgoing time information belongs. do it. The call origination time may be specified by a conventionally known time measuring means provided or accessible by the service providing server. In addition, when the transmission time is included in the transmission information in the data communication method adopted by the service providing server, the information may be used. It is desirable that the source information is encrypted by a conventionally known method in order to avoid forgery in the user terminal.

The output by the “output unit” of the “user terminal” includes visual output and auditory output. The “extended service request operation” is an operation performed on a user terminal that is permitted to access the service providing server, and may be an operation set in advance as an “extended service request operation”. There are a selection operation of a predetermined position on the screen, an input operation to a predetermined input member, a voice input of a predetermined voice, and the like. The “service providing server” may be a server that permits access only to a user who has been authenticated by a conventionally known authentication process and provides a predetermined service to the authenticated user, that is, a predetermined range of users. For example, a social networking server (SNS server) that provides a community site, which is a place for information exchange as a service, and a management server for a member-based site that provides predetermined information only to members as a service.

"Expansion providing system", if example embodiment, configured like constituted by a first server having a usage confirmation unit and the second server with extended service providing section, each part of the function is realized by a plurality of servers May be. Note that communication between servers in the case of being configured by a plurality of servers may adopt a conventionally known communication method. For example, in the case of being configured by the above two servers, confirmation in the usage confirmation process has been performed. May be transmitted from the first server to the second server by a conventionally known communication method. The “extended service” includes a service that provides predetermined information to the user and a service that continuously provides a predetermined state such as participation in a game or a virtual tour.

In particular, the extended providing system according to the present invention includes a linkage server that performs use confirmation processing and an extended service providing server. Therefore, it is possible to separate the process of confirming whether the user is using the service providing server and the process of providing the extended service to the user when the confirmation is made. As an extended service, when a predetermined state is continuously provided rather than simply being provided with information to the user terminal, a function for continuously managing the state is required, especially for a large number of users. When receiving a service, the processing load increases. However, with this configuration, it is possible to avoid the processing load from being borne by one server. This is also effective when different management operating companies manage the linkage server for checking the access state of the user terminal and the extended service providing server for providing the extended service. The “extended information” is not particularly limited as long as it is information accepted as “extended information” in the extended service providing server.

  The extended providing system generates the extended source information when an extended source information request for requesting extended source information for indicating that the extended information is transmitted from the linkage server is acquired from the linkage server. And an extended source information generation server (9) having an extended source information generation unit (90a) for transmitting to the linkage server, and the extended information generation unit of the linkage server is confirmed by the usage confirmation unit. The extended source information request for requesting the extended source information for the extended information to be generated is transmitted to the extended source information generation server, and the extended source information is generated as the extended source information. Acquired from the server, the extended source information is included in the corresponding extended information and transmitted to the user terminal, and the extended service providing server acquires from the user terminal Based on the extended source information included in the extended information, an extended call confirmation unit (50a) for confirming that the extended information is transmitted from the linkage server, the extended service providing unit includes the extended call confirmation unit When it is confirmed that the extension information is transmitted from the linkage server by the unit, access may be permitted to the user terminal that has transmitted the extension information, and provision of information regarding the extension service may be started.

  Thereby, the extended service provision server can confirm whether the extended information acquired from the user terminal is the information transmitted from the linkage server based on the extended source information. As a mode of confirming the sender based on the extended sender information, when the “extended sender information” is predetermined information, the extended sender information generator is made to encrypt the extended sender information by a conventionally known encryption method. The extended transmission confirmation unit may be configured to decode the encrypted extended transmission source information and confirm the information, or the extended transmission source information generation unit may have a unique extended transmission source for each extended information. Information is generated, the generated extended source information is held in the extended source information generation server, and the extended source information acquired from the user terminal is held by the extended source information generation server in the extended transmission confirmation unit. In such a case, the extended information may be confirmed to have been transmitted from the linkage server.

  The service providing server includes a user information storage unit (32b) that stores user information in which information about each of a plurality of users to be authenticated by the authentication process includes user identification information that identifies each user, The usage information transmission unit acquires the user information corresponding to the user of the user terminal that transmitted the usage information request from the user information storage unit, further includes the acquired user information in the usage information, and the linkage server When the confirmation in the use confirmation process is confirmed, the extended information generation unit generates the extended information including at least the user identification information of the user information included in the usage information, and provides the extended service provided by the extended service providing server The unit may perform a process of identifying each user based on the user identification information included in the extended information.

  Thereby, the extended service which identified each user with the user identification information which a service provision server hold | maintains can be provided. This is particularly effective when the extended service is a game in which a plurality of users participate.

  The linkage server includes an extended user information storage unit (82c) that stores the user information acquired from the user terminal, and the extension information generation unit of the linkage server performs confirmation in the use confirmation process. User information included in the acquired usage information is stored in the extended user information storage unit, the extended information including user identification information of the user information is generated, and the extended service providing unit of the extended service providing server includes the Using the user identification information of the user of the user terminal permitted to access as a search key, refer to the user information stored in the extended user information storage unit, and generate information on the extended service based on the user information Also good.

  Thereby, the extended service providing server can provide an extended service reflecting the user information held by the service providing server. If the user information included in the usage information is configured to include various information related to the user in addition to the user identification information, an extended service corresponding to various aspects of the user can be provided. In addition to the user identification information, the information included in the user information includes, for example, information on the user himself / herself that is not related to the use of the server providing system such as the user's age, height, hobby, etc. Information on the use of the server providing system such as the relationship with the user.

    When the use confirmation process confirms the extended information generation unit of the linkage server, extended user identification information that is identification information for the extended service providing server is added to the user identification information included in the user information. Generating and storing the user information in association with the corresponding extended user information in the extended user information storage unit, including the extended user identification information as the user identification information in the extended access information, and the extended service providing server. The extended service providing unit may perform a process of identifying each user by the extended user identification information. Thereby, in the extended providing system, the extended user identification information is used as information for identifying the user, so that the user can be identified by the code system unique to the extended providing system. For example, when the linkage server includes an extended user information storage unit, the user information may be searched using the extended user identification information as a search key.

The extended providing system includes a startup program (111) that starts up at the user terminal and causes the user terminal to function as the usage information request unit and the usage information transfer unit, and the user terminal as the extended information transmission unit. And a provision program storage unit (62) for storing a user terminal program (110) including an extension service program (112) configured to function as the extension service corresponding unit, and a program request from the user terminal If acquired, the program providing server (6) further includes a program providing unit (60a) for transmitting the user terminal program to the user terminal, and the user terminal receives the access after the access is permitted. When there is a service request operation, a program request is sent to the program providing server. Te, the acquired program for the user terminal, the boot program may further comprise a program activation unit for starting the (20e). As a result, since the activation program is provided and activated to the user terminal that has performed the request for the extended service, it is not necessary to set the activation program in the user terminal in advance. Therefore, as long as the user terminal is permitted to access the service providing server, the extended service can always be received.

Wherein the providing program storage unit, the user terminal program may be stored in association with unique service identification information in the extension services provided, before SL service providing server, the output of the user terminal that the access is permitted in part, to output a selection menu with selectable one of enhanced services from a plurality of types of enhanced services, the one enhanced service is selected as the request operation, the service identification information corresponding to the selected extended service storing the configured screen programmed to transmit to the program providing server said program request including a screen program storage unit comprises a (32a), said user terminal,

(Step S202). Steps S200 and S202 are operations in accordance with the screen program, whereby the control unit 20 of the user terminal 2 functions as the screen program execution unit 20d. Thereafter, the user terminal 2 displays a message “in preparation” on the monitor (step S204). The URL resolution server 7 that has received the URL request refers to the URL storage unit 72, searches for the URL information 121 associated with the game identification information 120 of the game A, and returns the URL information 121 to the user terminal 2 (step S300).

  The URL information 121 in this embodiment indicates the URL where the user terminal program 110a of the game A is stored, that is, the storage location where the user terminal program 110a is stored in the provided program storage unit 62 of the program providing server 6. The user terminal 2 that has acquired the URL information 121 transmits a program request to the URL indicated by the URL information 121 (step S206). The program providing unit 60a of the program providing server 6 that has acquired the program request downloads the user terminal program 110a stored in the URL indicated by the program request to the user terminal 2 (step S400). Then, the user terminal 2 activates the acquired user terminal program 110a (step S208). Thereby, the control unit 20 of the user terminal 2 functions as the program starting unit 20e. With this activation, execution of the activation program unit 111 of the user terminal program 110a is started, and thereafter, the user terminal 2 operates according to the user terminal program 110a.

    Subsequently, in the user terminal 2 where the user terminal program 110a is activated, the control unit 20 operates according to the activation program 11, and first, a usage information request is transmitted to the SNS server 3 (step S210). Thereby, the control unit 20 functions as the usage information request unit 20a. The SNS server 3 that has received the usage information request generates usage information by the usage information transmission unit 30a and transmits the usage information to the user terminal 2 (step S102). The usage information includes user information 107 of the user who operates the user terminal 2, electronic signature information, and transmission time information indicating the transmission time of the usage information. Since the SNS server 3 has already established a link with the user terminal 2, for example, the user of the user terminal 2 can be identified from the port number, and the user information 107 of the identified user is extracted from the user related information 100. The electronic signature information is information for proving that the usage information is transmitted from the SNS server 3. The scheme of the electronic signature information is not limited. For example, in the case of the public key cryptosystem, the signature information of the SNS server 3 is encrypted with the public key. The public key may be included in the program request and transmitted to the SNS server 3, for example.

  The user terminal 2 that has acquired the usage information transmits the usage information to the linkage server 8 (step S212). Thereby, the control unit 20 functions as the usage information transfer unit 20b. In the linkage server 8 that has acquired the usage information, a usage confirmation process is performed by the usage confirmation unit 80a (step S500). In the usage confirmation process, based on the usage information, the user corresponding to the usage information, that is, the user of the user terminal 2 that transmitted the usage information is authenticated by the SNS server 3, that is, a user using “MySNS”. It is confirmed whether or not. When it is confirmed by the usage confirmation process that the user is using “MySNS”, “confirmation” is set in the confirmation result, and it is not confirmed that the user is using “MySNS” “Error” is set in the confirmation result. Details of the usage confirmation process will be described later.

  Subsequently, it is determined whether or not the user using “MySNS” has been confirmed based on the confirmation result of the use confirmation process (step S502). If the confirmation result is “error”, an error is detected. A message is transmitted to the user terminal 2 (step S504). In the user terminal 2 that has received the error message, for example, the error message is displayed on the monitor (step S214). On the other hand, when the confirmation result of the use confirmation process is “confirmation”, the linkage server 8 generates an extended user ID 130 associated with the user ID included in the user information 107 (step S506).

  The extended user ID 130 is identification information for identifying a user in the extended providing system 4. Therefore, the identification information unique to each user in the extension providing system 4 may be used. In this embodiment, it is used as information for identifying the user in the game provided by the extended providing system 4. Subsequently, the linkage server 8 associates the generated extended user ID 130 with the user ID 101 and stores them in the user ID storage unit 82a, and stores the acquired usage information 107 in the personal information storage unit 82b (step S508). Then, a game authentication information request is transmitted to the game authentication information issuing server 9 (step S510).

  The game authentication information issuing server 9 that has acquired the game authentication information request generates unique game authentication information in response to the request (step S600). The game authentication information is information for certifying that an extended access request to be described later is transmitted from the linkage server 8. Since one extended access information is generated for one game authentication information request, the game authentication information unique to each game authentication information request is also unique to each extended access information. The generated game authentication information is transmitted to the linkage server 8 and stored in the game authentication information storage unit 92 (step S602).

  The linkage server 8 generates extended access information including the game authentication information acquired from the game authentication information issuing server 9 and the extended user ID 130 as extended information (step S512), and the generated extended access information is transmitted to the user terminal 2. Transmit (step S514). Thereby, the control unit 80 functions as the extended information generating unit 80b. The user terminal 2 that has acquired the extended access information starts processing according to the game program unit 112 of the user terminal program 110a. As processing according to the game program unit 112, the user terminal 2 first transmits the acquired extended access information to the game server 5 (step S216). Thereby, the control unit 20 functions as the extended information transmitting unit 20c.

  The game server 5 that acquired the extended access information performs an expansion confirmation process (step S700). In the expansion confirmation process, the game server 5 confirms that the acquired extended access information is transmitted from the linkage server 8. Specifically, the game authentication information issuing server 9 is accessed to check whether or not the game authentication information included in the extended access information exists in the game authentication information storage unit 92. Thereby, the control unit 90 of the game authentication information issuing server 9 functions as a game authentication information generation unit 90a, that is, an extended transmission source information generation unit.

  When the game authentication information exists in the game authentication information storage unit 92, “confirmation” is set as the confirmation result, and when there is no game authentication information, “error” is set as the confirmation result. Subsequently, it is determined whether or not the confirmation result is “confirmation” (step S702). If the confirmation result is “error”, the game server 5 transmits an error message to the user terminal 2 (step S704). In the user terminal 2 that acquired the error message, for example, the error message is displayed on the monitor (step S218).

  If the confirmation result of the extended confirmation process is “confirmed”, the game server 5 establishes a link with the user terminal 2 that has transmitted the extended access information and permits access from the user terminal 2 (step S706). Thereafter, the user terminal 2 is set as one of the game clients, and for example, a game start screen is transmitted as information related to the extended service (step S708). Thereby, the control unit 50 functions as the extended service providing unit 50b. Furthermore, the extended service providing unit 50b has a function as a conventionally known game server. For example, user operation information is received from the user terminal 2 that is a game client, the game situation is updated according to the operation information, and the update information is transmitted to the user terminal 2 as information related to the extended service provision information.

  On the other hand, the user terminal 2 that has established a link with the game server 5 can communicate with the game server 5 as a game client of the game A, and operates as a conventionally known game client. For example, a game start screen from the game server 5 is displayed on the monitor, and thereafter, user operation information is transmitted to the game server 5, and a screen corresponding to the update information from the game server 5 is displayed (step S220). The operation as a game client is controlled by the extended service corresponding unit 20 f of the control unit 20.

  The game server 5 that has established a link with the user terminal 2 transmits a personal information reference request including the extended user ID 130 as a search key to the linkage server 8 (step S710), and the nickname 102 and my friend corresponding to the extended user ID. Information 103 can be acquired and processing can be performed based on the acquired information. The acquired nickname 102 is set as the name of the user's avatar appearing on the game screen, for example. In addition, for example, it is possible to set the my friend information 103 so as to advance the game in cooperation with a friend's user. At that time, the game server 5 may acquire the corresponding extended user ID by inquiring the user ID of the user set in the my friend information 103 to the linkage server 8.

  On the other hand, the linkage server 8 that has acquired the personal information reference request from the game server 5 transmits the user's nickname 102 and my friend information 103 corresponding to the extended user ID, which is a search key, to the game server 5 as provided information (step) S516). Specifically, by referring to the user ID storage unit 82a, the user ID 101 corresponding to the extended user ID 130 included as a search key in the personal information reference request is specified, and further, by referring to the personal information storage unit 82b Then, the user information 107 corresponding to the specified user ID 101 is searched, and the provided information is generated by extracting the nickname 102 and the my friend information 103 of the searched user information 107.

    The flow of processing performed in the usage confirmation processing will be described with reference to the flowchart of FIG. The usage confirmation process is controlled by the usage confirmation unit 80a of the linkage server 8. The usage confirmation process is a process for confirming that the user of the user terminal 2 that transmitted the usage information is a user authenticated by the SNS server 3 (a user using “MySNS”). First, in step S800, a sender confirmation process is performed. In the sender confirmation process, it is confirmed whether or not the sender of the usage information is the SNS server 3 based on the electronic signature information included in the usage information. For example, in the case of the public key cryptosystem, the signature encrypted with the private key paired with the public key used in the SNS server 3 is decoded, and it is confirmed whether or not the decoded signature information indicates the SNS server 3 To do.

  If the decoded signature indicates the SNS server 3, it is determined in step S802 that there is no confirmation error, and the process proceeds to step S804. In step S804, a transmission time confirmation process is performed. In the transmission time confirmation process, it is determined whether or not the user of the user terminal 2 is a user who is currently authenticated by the SNS server 3 based on the transmission time information included in the usage information. In this embodiment, the transmission time when the usage information is transmitted from the SNS server 3 is specified by the transmission time information, and the time lag between the specified transmission time and the current time is calculated.

  When the time lag is within a predetermined range, the user of the user terminal 2 is confirmed as a user authenticated by the SNS server 3. If it is confirmed as an authenticated user, it is determined in step S806 that there is no confirmation error, the process proceeds to step S808, the confirmation result is set to “confirmed”, and the use confirmation process is terminated. As described above, in this embodiment, when the time lag is within a predetermined range, the user terminal that has transmitted the usage information indicates that the usage information has not been transmitted from the SNS server 3 to the user terminal 2 for a predetermined time or longer. The second user is regarded as a user authenticated by the SNS server 3.

  If the encrypted signature information cannot be decoded or the decoded signature information does not indicate the SNS server 3 in the transmission source confirmation processing in step S800, it is determined as a confirmation error in step S802, and step S810 is performed. Go to, set the confirmation result to "error" and end the usage confirmation process. If the time lag in the outgoing time confirmation process in step S804 exceeds a predetermined range, the user terminal 2 is authenticated since the user terminal 2 has been authenticated by the SNS server 3 and is currently authenticated. Therefore, in step S806, it is determined as a confirmation error, the process proceeds to step S810, the confirmation result is set to “error”, and the use confirmation process is terminated.

  The present invention is not limited to the above form and may be implemented in various forms. For example, the service providing server 3 is not limited to the SNS server 3 that provides the community site, and permits access to a user who is authenticated based on predetermined authentication information, and provides a predetermined service to the user who has permitted the access. Any server can be used. The network N of the service expansion system 1 may be a closed network that can be accessed only by a predetermined number of user terminals, and the network N is not provided. For example, each component in the service expansion system 1 is connected by a dedicated line. May be. If the URL for holding the user terminal program 110 is fixed, the URL resolution server 7 may not be provided. In this case, instead of the URL request, a program request having the URL of the program providing server 6 holding the target user terminal program 110 as a transmission destination may be set in the screen program.

  One game server 5 may be configured to function as a server for three games A, B, and C. In this case, the user terminal program 110 of all games is set so that the user terminal 2 transmits the extended access information to the same game server 5, and the game identification of the selected game is included in the transmitted extended access information. What is necessary is just to set so that the information 120 may be included. And what is necessary is just to comprise in the game server 5 so that the process according to the game identification information 120 may be performed.

  One extended providing system 4 may correspond to a plurality of SNS servers 3. In this case, for example, a community ID for identifying a community managed by each SNS server 3 is configured to be included in the usage information. As the community ID, information indicating transmission source information included in transmission data of a general communication method may be used. Then, the linkage server 8 stores the user information 107 and the community ID in association with each other in the personal information storage unit 82b. The game server 5 acquires a community ID of a specific user from the linkage server 8 in the same manner as the nickname 102, and performs processing so that a game is played between users belonging to the same community, for example.

  Further, as with the extended user ID, the linkage server 8 generates an extended community ID used in the extended system 4 for each community ID, and stores a community ID storage unit that stores the corresponding relationship in the storage unit 82. It may be provided.

  When there is one game provided as an extended service, the URL resolution server 7 and the program providing server 8 may not be provided. FIG. 17 shows a system configuration diagram of the service extension system 1 ′ in this case. In the service extension system 1 ′, the user terminal program 110 is held in the storage unit 82 of the linkage server 8, and the game server 5, the linkage server 8, and the game authentication information issuing server 9 constitute the extension provision system 4. In the service expansion system 1 ′, a screen program for the community start screen SI may be configured such that when a game is selected on the community start screen SI, a program request is transmitted from the user terminal 2 to the linkage server 5. And the user terminal 2 should just start the program acquired from the linkage server 5. FIG.

  When only the specific user terminal 2 constitutes the service expansion system 1, the user terminal program 110 may be stored in the user terminal 2 in advance. In this case, when a predetermined game is selected on the community start screen SI as the screen program of the community start screen SI, the user terminal program 110 corresponding to the selected game is immediately started on the user terminal 2. What is necessary is just to comprise.

  Note that the game authentication information generation unit 90a and the game authentication information storage unit 92 of the game authentication information issue server 9 are provided in the control unit 80 and the storage unit 82 of the linkage server 8, respectively, and the game authentication information issue server 9 is omitted. Good. In that case, in the expansion confirmation process in the game server 5, the authenticity of the game authentication information acquired from the user terminal 2 is confirmed by accessing the linkage server 8.

(2) Second form The extended service is not limited to the network game with other users as in the first form. For example, predetermined information for the user (including a game played by one user) It may be a service that provides FIG. 18 shows an example of a service extension system 300 as a second form for providing such an extension service. Hereinafter, the parts different from the first embodiment will be mainly described. In the service extension system 300 of FIG. 18, the extension providing system 4 includes only the extension server 310. The SNS server 3 of the service extension system 300 provides a community site for students of a specific cooking school as a service, and the extension server 310 serves as an extension service for users (students) who are authenticated by the SNS server 3. The case where “recommended restaurant information” is provided will be described.

  As shown in FIG. 19, the hardware configuration of the extension server 310 includes a communication unit 311, a storage unit 312, and a control unit 313, and the storage unit 312 holds a user terminal program 110 ′ and restaurant information RI. The control unit 313 mainly functions as a usage confirmation unit 313a and an extended service providing unit 313b. In the restaurant information RI, for each of a plurality of restaurants, information relating to the restaurant such as items such as a dish type, a price, a place, and a use age group is set. The user terminal program 110 ′ causes the user terminal 2 to request usage information from the SNS server 3, transmits the usage information acquired from the SNS server 3 to the extension server 310, and “recommended restaurant information from the extension server 310. Is displayed on the monitor. That is, the control unit 20 of the user terminal 2 is configured to function as a usage information request unit 20a, a usage information transfer unit 20b, and an extended service provision unit 20b. ,

  The user related information 100 ′ held by the SNS server 3 includes, for example, a student ID as a user ID, a password, an age, and a class to which the student belongs, and the user information 107 ′ includes a student ID, age, and class. included. The screen program of the community start screen SI is configured such that a selection area SId for selecting “recommended restaurant information” is displayed and a program request is transmitted to the expansion server 310 when the selection area is selected. .

  The flow of processing until the user terminal 2 is authenticated by the SNS server 3 and “recommended restaurant information” is displayed on the monitor will be described with reference to the sequence diagram of FIG. The processing in each configuration is controlled by the control units 20, 30, 313 of each configuration. First, the process of displaying the community start screen SI on the user terminal 2 through step S110 and step S230 is the same as in the first embodiment. When “recommended restaurant information” is selected on the community start screen SI, the user terminal 2 transmits a program request to the extension server 310 (step S232). The expansion server 310 that has acquired the program request downloads the user terminal program 110 ′ to the user terminal 2 (step S520).

  The user terminal 2 that has acquired the user terminal program 110 'activates it (step S234), and transmits a usage information request to the SNS server 3 (step S236). Thereby, the control unit 20 of the user terminal 2 functions as the usage information request unit 20a. The SNS server 3 that acquired the usage information generates and transmits usage information including the user information 107 ′, transmission time information, and electronic signature information (step S112). Thereby, the control unit 30 of the SNS server 3 functions as the usage information transmitting unit 30a. The user terminal 2 that has acquired the usage information transmits the usage information to the extension server 310 (step S238). Thereby, the control unit 20 of the user terminal 2 functions as the usage information transfer unit 20b. The extended server 310 that has acquired the usage information performs a usage confirmation process similar to that of the first embodiment (step S522). Thereby, the control unit 313 of the expansion server 310 functions as the usage confirmation unit 313a.

  Subsequently, the confirmation result by the use confirmation process is referred to (step S524). If the confirmation result is “error”, the extension server 310 transmits an error message to the user terminal 2 (step S526). Then, the user terminal 2 displays the acquired error message on the monitor (step S240). If the confirmation result is “confirmation”, the extension server 310 generates “recommended restaurant information” as selection information and transmits it to the user terminal 2 (step S528). Thereby, the control unit 313 of the extension server 310 functions as the extension service providing unit 313b.

  The “recommended restaurant information” is generated, for example, by referring to the age and affiliation class of the user information 107 ′ included in the usage information and extracting a restaurant of a dish or price corresponding to the age and affiliation class from the restaurant information RI. . The user terminal 2 that has acquired “recommended restaurant information” displays the information on the monitor (step S242). Thereby, the control unit 20 of the user terminal functions as the extended service corresponding unit 20c.

  With the above processing, restaurant information corresponding to the class and age to which the user belongs can be provided to the user who has selected “recommended restaurant information” on the community start screen SI. When the information provided by the extension server 310 is specified information, it is not necessary to include the user information 107 ′ in the usage information, and the extension server 310 sends the usage information to the user terminal 2 that has transmitted the usage information. The specified information may be transmitted to the user terminal 2 as information related to the extended service.

  Further, when a plurality of extension servers 310 are provided, and each extension server 310 provides the user with information on different themes as an extension service, the extension providing system 4 is changed to the URL resolution server 7, the program providing server 6, and the plurality of extension servers 310. The extension server 310 may be used. The program providing server 6 holds a user terminal program 110 ′ for each expansion server 310. Each user terminal pro program 110 ′ is similar to the user terminal program 110 ′ in the service expansion system 300, but is set so that the transmission destination of the usage information is the expansion server 310 that provides the selected expansion service. Has been.

  In the screen program of the community start screen SI, a selection area SId in which a plurality of types of extended services are listed is displayed on the community screen SI, and a URL request including service identification information of the extended service selected by the user's selection operation is a URL request. It is set so as to be transmitted to the resolution server 7. Subsequent operations of the URL resolution server 7 and the program providing server 6 are downloaded from the program providing server 6 to the user terminal 2 in the same manner as in the first embodiment.

  As in the first embodiment, when only a specific user terminal 2 constitutes the service expansion system 300, the user terminal program 110 ′ may be stored in the user terminal 2 in advance. In that case, the user terminal program 110 ′ may be configured to be immediately activated on the user terminal 2 when a predetermined game is selected on the community start screen SI.
