Description

  The present invention relates to an information processing system, a terminal device, and a program that handle conference material information used in a conference.

  In a meeting, paper-based meeting materials are generally distributed to participants. However, paperlessness is required from the viewpoints of business efficiency, cost reduction, and reduction of environmental load. In particular, office work in recent years has become increasingly sophisticated with information and communication technology, and if meeting materials can be distributed to the necessary participants as needed as electronic data, there is little need to distribute paper-based meeting materials. Conceivable.

  A meeting material distribution system has been proposed as one of the paperless solutions. In the conference material distribution system, conference participants can share and browse conference materials electronically using a terminal device such as a tablet.

  Meeting material distribution systems have already been widely put into practical use. For example, Patent Document 1 proposes a system that not only shares conference materials between terminal devices but also has a function of cooperating with a printer. Patent Document 2 proposes a system that distributes conference materials between terminal devices without using a central server. Patent Document 3 proposes a system that uses a broadcast network in addition to a communication line in order to improve the distribution efficiency of conference materials.

  In addition, a system for improving the security of the conference material distributed has been proposed. For example, Patent Document 4 proposes a system that periodically performs communication between a server and a terminal device and erases data of the terminal device when authentication fails. Patent Document 5 proposes a system that automatically deletes meeting material data distributed in a meeting when a participant leaves. In Patent Document 6, the browsing material browsed during the meeting and the subsequent distribution material are managed separately, the browsing material is deleted from the terminal device at the end of the conference, and further according to the attribute of the conference material A system for determining whether or not a distribution material can be transmitted to a terminal device has been proposed.

  In the case of paper-based conference materials, the distribution range of the distributor can be physically controlled. For example, in the case of important meeting material that should not be leaked to the outside, the distributor can distribute the meeting material only to the participants of the meeting.

  However, in a conference material distribution system that can transmit conference materials as electronic data to a remote location via a network, the conference materials can be distributed regardless of whether the other party is near the distributor. Meeting materials could be distributed to non-participants.

It is an example of a participant list screen displayed on the display unit 33 of the terminal device B.

  Hereinafter, an information processing system, a terminal device, and a program according to the present embodiment will be described with reference to the drawings.

  FIG. 1 is a diagram showing the overall configuration of the information processing system 1. In the information processing system 1, the information processing device 10 and the terminal device 30 are connected via the network 20. The network 20 is, for example, the Internet, a LAN (Local Area Network), a public line, a mobile phone network, or the like. The information processing apparatus 10 is a server constructed on the network 20, for example. Although details will be described later, the information processing apparatus 10 includes a plurality of APIs (Application Programming Interfaces). For example, the information processing apparatus 10 includes a login API, a terminal report API, a material access API, a participant management API, and the like.

  The information processing apparatus 10 includes a server control unit 11, a database 12, a Web communication unit 13, and a set recognition unit 14. The database 12 stores various information such as the proximity list L1 and the conference participant list L2. Details of the proximity list L1 and the conference participant list L2 will be described later. The server control unit 11 controls writing and reading of information with respect to the database 12. The web communication unit 13 is a communication interface for the information processing apparatus 10 to communicate with the terminal device 30. As will be described in detail later, the set recognition unit 14 recognizes a set made up of a plurality of terminal devices that are close to each other.

  The terminal device 30 is, for example, a tablet type terminal device. Note that the terminal device 30 may be a terminal device such as a notebook PC or a smartphone. The terminal device 30 includes a terminal control unit 31, a wireless LAN communication unit 32, a display unit 33, a short-range wireless communication unit 34, and a storage unit 35.

  An application program for tablets is installed in the storage unit 35 of the terminal device 30. The terminal control unit 31 reads the application program from the storage unit 35 and executes it. The wireless LAN communication unit 32 is a wireless communication interface for the terminal device 30 to communicate with the information processing apparatus 10.

  The display unit 33 is a user interface such as a touch panel capable of displaying information. The near field communication unit 34 is a near field communication interface such as Bluetooth (registered trademark) Low Energy. Although FIG. 1 shows an example in which one terminal device 30 is connected to the network 20, a plurality of terminal devices are actually connected to the network 20.

  The terminal control unit 31 issues identification information for specifying its own terminal device, and stores the issued identification information in the storage unit 35. For example, the terminal control unit 31 issues a number such as a UUID (Universally Unique Identifier) such as a UUID (Universally Unique Identifier) that is low enough to ignore the possibility of overlapping with other terminal device identification information.

  The terminal control unit 31 controls the wireless LAN communication unit 32 to transmit the issued identification information to the information processing apparatus 10. The web communication unit 13 in the information processing apparatus 10 receives the identification information transmitted from each terminal device 30. The server control unit 11 stores the identification information received by the web communication unit 13 in the database 12. In the present embodiment, the terminal device 30 issues identification information, but the information processing device 10 may issue identification information.

(Set recognition process)
FIG. 2 is a diagram showing a process for recognizing a set composed of a plurality of adjacent terminal devices. As illustrated in FIG. 2, the plurality of terminal devices 30 a to 30 f communicate with the information processing device 10 via the network 20. The terminal device 30a is a terminal device of a conference organizer, and the terminal devices 30c, 30d, and 30f are terminal devices of conference participants. In the example illustrated in FIG. 2, identification information ID1 to ID6 is allocated to the plurality of terminal devices 30a to 30f, respectively.

  The terminal devices 30a to 30f read their own identification information from the storage unit 35, and periodically broadcast the read identification information. In addition, the terminal devices 30 a to 30 f receive the identification information broadcast from other terminal devices, and transmit the identification information received within a certain period to the information processing device 10. The set recognition unit 14 of the information processing device 10 receives the identification information transmitted from each of the terminal devices 30a to 30f and recognizes a set of a plurality of terminal devices that are close to each other.

  For example, in the example shown in FIG. 2, the terminal device 30 a associates its own identification information ID <b> 1 with the identification information ID <b> 2 to ID <b> 4 received from a plurality of adjacent terminal devices and transmits it to the information processing device 10. The identification information is transmitted using the terminal report API. Similarly to the terminal device 30a, the other terminal devices 30b to 30f are also associated with their own identification information and identification information received from a plurality of adjacent terminal devices and transmitted to the information processing device 10.

  Based on the received information, the set recognition unit 14 of the information processing apparatus 10 recognizes the set A configured by the terminal devices 30a to 30d and recognizes the set B configured by the terminal devices 30e and 30f. For example, the information processing apparatus 10 has received its own identification information ID1 and identification information ID2 to ID4 of adjacent terminal devices from the terminal device 30a. For this reason, the information processing apparatus 10 determines that the terminal devices 30a to 30d belong to the same set. The information processing apparatus 10 stores these recognized sets in the database 12 as a proximity list L1. In the proximity list L1, for each set recognized by the set recognition unit 14, identification information of terminal devices belonging to the set is registered.

  According to this embodiment, each terminal device 30 can recognize the terminal devices 30 that are close to each other. Short-range wireless communication is generally unstable, and the terminal device 30 cannot receive all broadcasts from the terminal device 30 in the vicinity. However, according to the present embodiment, if one terminal device 30 can receive the broadcast of the other terminal device 30, the information processing apparatus 10 can determine that these terminal devices 30 belong to the same set. . For this reason, it becomes possible to recognize the terminal device 30 which adjoins stably.

  FIG. 3 is a sequence diagram showing a series of processes shown in FIG. In FIG. 3, terminal devices 30a to 30c are shown as terminal devices A to C, respectively. First, the terminal device A logs in to the server control unit 11 of the information processing device 10 (step S1). The login process is performed using a login API.

  In the database 12 of the information processing apparatus 10, the ID and password of the user of the terminal device 30 are registered in advance. The terminal device A transmits the ID and password input by the user to the server control unit 11. Based on the ID and password received from the terminal device A, the server control unit 11 refers to information registered in the database 12 and determines whether or not login is permitted.

  If the login is permitted, the server control unit 11 transmits a login completion notification to the terminal device A (step S2). At this time, the server control unit 11 issues a session key, which is a temporary key that is difficult to predict, and transmits it to the terminal device A. By using this session key, the server control unit 11 can recognize which terminal device the access is from.

  When the login is completed, the terminal device A instructs the short-range wireless communication unit 34 to start transmitting identification information (step S3). In response to this, the short-range wireless communication unit 34 repeatedly broadcasts identification information at regular time intervals (step S4).

  Also, the terminal device A instructs the short-range wireless communication unit 34 to start receiving identification information (step S5). In response to this, the short-range wireless communication unit 34 receives the identification information broadcast from another terminal device (steps S6 and S7). Thereafter, the short-range wireless communication unit 34 uses the terminal report API to transmit identification information of a plurality of adjacent terminal devices to the server control unit 11 together with its own identification information (step S8). The identification information is transmitted using the terminal report API.

  The server control unit 11 updates the proximity list L1 stored in the database 12 based on the identification information received from the terminal device A (step S9). When the update of the proximity list L1 is completed, the server control unit 11 transmits an update completion notification to the terminal device A (step S10). Note that the processing in steps S6 to S10 is repeatedly executed at regular intervals.

(Meeting material distribution process)
FIG. 4 is a diagram showing a process for distributing conference material information. FIG. 4 shows, as an example, processing of the entire information processing system 1 when the terminal device 30a distributes conference materials. First, the terminal device 30 a of the meeting organizer transmits meeting material information to the information processing apparatus 10. The information processing apparatus 10 registers the conference material information received from the terminal device 30a in the database 12 after confirming that the terminal device 30a is the terminal device of the meeting organizer.

  When the information processing apparatus 10 receives the meeting material information acquisition request from the terminal apparatus 30c, the information processing apparatus 10 confirms that the terminal apparatus 30c is the terminal apparatus of the conference participant and that the terminal apparatus 30c belongs to the set A. Thus, the conference material information registered in the database 12 is transmitted to the terminal device 30c. Similarly, the information processing apparatus 10 transmits the conference material information to the terminal device 30d.

  On the other hand, the terminal device 30b is neither a conference organizer's terminal device nor a participant's terminal device. For this reason, even if the information processing apparatus 10 receives the acquisition request for the conference material from the terminal device 30b, it does not transmit the conference material to the terminal device 30b. The terminal devices 30e and 30f belong to a set B different from the set A to which the terminal device 30a of the meeting organizer belongs. For this reason, the information processing apparatus 10 does not transmit the conference material to the terminal devices 30e and 30f even if the acquisition request for the conference material is received from the terminal devices 30e and 30f.

  In addition, although the terminal device 30f is a terminal device of the participant of a meeting, since the terminal device 30f does not belong to the set A, it is considered that the owner of the terminal device 30f is absent from the meeting. Therefore, even when the information processing apparatus 10 receives a conference material acquisition request from the terminal device 30f, the information processing device 10 does not transmit the conference material to the terminal device 30f. However, when the access requirement information is set so that the absentee can access the conference material information, the information processing apparatus 10 transmits the conference material information to the terminal device 30f.

  Further, when the information processing apparatus 10 receives a meeting material acquisition request from the terminal device 30a of the organizer, the information processing apparatus 10 transmits the meeting material to the terminal device 30a. The registration of the conference material information is performed not only by a request from the conference organizer but also by a request from a conference participant.

  FIG. 5 is a sequence diagram showing a series of processes shown in FIG. The process shown in FIG. 5 is executed using a material access API. In FIG. 5, the terminal device 30 a of the meeting organizer is shown as the terminal device A, and the terminal devices 30 b to 30 f are collectively shown as the terminal device B.

  The terminal device A transmits the conference material information together with the identification information of the terminal device A to the server control unit 11 of the information processing device 10 (step S21). At this time, the terminal device A also transmits to the server control unit 11 the conference specifying information for specifying the conference and the access requirement information indicating whether or not the conference material information is accessible to those who are absent from the conference. Based on the received identification information of the terminal device A, the server control unit 11 refers to the database 12 to determine whether the terminal device A is a conference organizer or a participant's terminal device.

  When the terminal device A is a conference organizer or participant's terminal device, the server control unit 11 registers the received conference material information in the database 12 (step S22). At this time, the server control unit 11 registers the conference specifying information, the conference material information, and the access requirement information in the database 12 in association with each other. When the registration of the conference material information is completed, the server control unit 11 transmits a registration completion notification to the terminal device A (step S23).

  If the terminal device A is not a conference organizer or participant's terminal device, the server control unit 11 does not register the received conference material information in the database 12 and transmits a registration rejection notification to the terminal device A. To do.

  On the other hand, the terminal device B transmits a conference material acquisition request to the server control unit 11 together with the identification information of the terminal device B (step S24). The terminal device B accesses the server control unit 11 via HTTPS (Hyper Text Transfer Protocol Secure). The acquisition request includes meeting specifying information for specifying a meeting. Upon receiving the meeting material acquisition request from the terminal device B, the server control unit 11 acquires the meeting participant list L2 from the database 12 based on the received meeting specifying information. The server control unit 11 determines whether or not the received identification information of the terminal device B is included in the participant list L2 (step S25).

  When the identification information of the terminal device B is not included in the participant list L2 (Case 1), the terminal device B does not have an access right to the conference material information. For this reason, the server control unit 11 does not transmit the conference material information to the terminal device B, but transmits a rejection notice (step S26). On the other hand, when the identification information of the terminal device B is included in the participant list L2 (Case 2), the server control unit 11 reads the conference material information from the database 12 (step S27).

  Next, the server control unit 11 refers to the access requirement information from the database 12 and determines whether or not the conference material information can be accessed by those who are absent from the conference. When access to the conference material information for the absentee is permitted (Case 2-1), the server control unit 11 transmits the conference material information to the terminal device B (step S28).

  On the other hand, when access to the conference material information for the absentee is not permitted (Case 2-2), the server control unit 11 refers to the proximity list L1 stored in the database 12, and the terminal device A and the terminal device B It is determined whether they belong to the same set (step S29).

  When the terminal device A and the terminal device B belong to the same set (Case 2-2-1), the server control unit 11 transmits the conference material information to the terminal device B (step S30). On the other hand, when the terminal device A and the terminal device B do not belong to the same set (Case 2-2-2), the server control unit 11 does not transmit the conference material information to the terminal device B but transmits a rejection notification (step S31). ).

  6-9 is a figure which shows an example of the screen displayed on the display part 33 of the terminal device 30. As shown in FIG. Here, the database 12 includes the conference material information 41 and 42 from the terminal device A of the conference organizer, the conference material information 43 from the conference device terminal B, and the terminal device C of the conference participant. It is assumed that the conference material information 44 is registered. It is assumed that the conference material information 42 and 43 are registered in the access requirement information, assuming that only the attendees of the conference can access. Further, it is assumed that the terminal device D is not a terminal device of a conference participant.

  FIG. 6 is a diagram illustrating an example of a screen displayed on the display unit 33 of the terminal device A of the organizer. As shown in FIG. 6, all registered conference material information 41 to 44 are displayed on the display unit 33 of the terminal device A of the organizer. For this reason, the organizer's terminal device A can access all the conference material information 41 to 44.

  FIG. 7 is a diagram illustrating an example of a screen displayed on the display unit 33 of the terminal device B of the participant. The owner of the terminal device B is attending the conference, and the terminal device B belongs to the same set as the terminal device A of the organizer. In this case, as shown in FIG. 7, all registered conference material information 41 to 44 is displayed on the display unit 33 of the terminal device B. For this reason, the terminal device B can access all the conference material information 41 to 44.

  FIG. 8 is a diagram illustrating an example of a screen displayed on the display unit 33 of the terminal device C of the participant. Note that the owner of the terminal device C is absent from the conference, and the terminal device C does not belong to the same set as the terminal device A of the organizer. In this case, as shown in FIG. 8, conference material information 41 and 44 are displayed on the display unit 33 of the terminal device C. However, since the owner of the terminal device C is absent from the conference, the conference material information 42 and 43 is not displayed on the display unit 33 of the terminal device C. For this reason, the terminal device C can access the conference material information 41 and 44, but cannot access the conference material information 42 and 43.

  FIG. 9 is a diagram illustrating an example of a screen displayed on the display unit 33 of the terminal device D. Since the owner of the terminal device D is not a participant in the conference, none of the conference material information 41 to 44 is displayed on the display unit 33 of the terminal device D, and a message “access not possible” is displayed on the display unit 33. . For this reason, the terminal device D cannot access any of the conference material information 41 to 44.

(Participation application processing)
FIG. 10 is a diagram illustrating a conference participation application process. First, the terminal device 30a of the meeting organizer instructs the information processing apparatus 10 to create a meeting using the participant management API. In response to this, the information processing apparatus 10 registers the participant list L2 in which the identification information of the terminal device 30a is registered in the database 12 as a conference organizer. The participant list L2 is registered in the database 12 in association with the conference specifying information. However, at this stage, the participant has not yet been registered in the participant list L2.

  As shown in FIG. 10, when the information processing apparatus 10 receives a participation application from the terminal apparatus 30b, the terminal apparatus 30b belongs to the same set A as the terminal apparatus 30a of the conference organizer, and therefore the information processing apparatus 10 is a terminal apparatus. Approve the 30b application. Then, the information processing apparatus 10 registers the identification information of the terminal device 30b in the participant list L2. On the other hand, when the information processing apparatus 10 receives a participation application from the terminal apparatus 30e, the terminal apparatus 30e does not belong to the set A, and thus the information processing apparatus 10 rejects the participation application of the terminal apparatus 30b.

  FIG. 11 is a sequence diagram showing a series of processes shown in FIG. The process shown in FIG. 11 is executed using a participant management API. In FIG. 11, the terminal device 30a of the meeting organizer is shown as the terminal device A, and the terminal devices 30b to 30f are collectively shown as the terminal device B. FIG. 12 is an example of a participation application screen displayed on the display unit 33 of the terminal device B.

  In response to a request from the terminal device B, the information processing device 10 receives the conference identification information of the conference in which the terminal device B participates, the conference identification information of the conference hosted by the terminal device near the terminal device B, and Is transmitted to the terminal device B. The terminal device B displays the participation application screen shown in FIG. 12 on the display unit 33 based on the meeting specifying information received from the server control unit 11.

  As shown in FIG. 12, the participation application screen includes “conference 2” in which the terminal device B participates and “conference 1” hosted by the terminal device A that belongs to the same set as the terminal device B. And are displayed. When the terminal device B makes an application for participation in “Conference 1” hosted by the terminal device A, the application key 51 is selected by the owner of the terminal device B. The application key 51 functions as a participation application means.

  When the application key 51 is selected, the terminal device B transmits a conference participation application to the server control unit 11 of the information processing device 10 together with the identification information of the terminal device B (step S41). The participation application includes the identification information of the terminal device B and the conference specifying information of the conference to which the terminal device B intends to participate. The server control unit 11 refers to the proximity list L1 stored in the database 12 based on the received identification information of the terminal device B, and determines whether the terminal device B belongs to the same set as the terminal device A of the conference organizer. Is determined (step S42).

  When the terminal device A and the terminal device B do not belong to the same set (Case 1), the server control unit 11 transmits a rejection notification to the terminal device B (step S43).
