Description

  The present invention relates to a conference material sharing system and a conference material sharing method, and more particularly to a technique suitable for use in easily sharing conference materials while maintaining security.

  Today, when a meeting or a meeting is held at a company, a school, a research institution, or the like, it is widely performed that a meeting material is created as an electronic document and distributed to meeting participants. At that time, shared folders using SMB (Server Message Block) or NFS (Network File System) are often used as means for sharing conference materials. Also, file transfer functions such as T.127 (Multipoint binary file transfer protocol) are often used.

  When meeting materials are shared, data containing confidential information may be handled, so security must be ensured to prevent leakage of confidential data. On the other hand, it is desirable to share the document so that it can be easily read out without taking the trouble of inputting a password during the meeting.

Patent Document 1 discloses a technique for performing authentication using a non-contact ID card carried by each conference participant and displaying the conference material created by the conference participant on the conference host terminal.
Japanese Patent Application Laid-Open No. 2004-228688 discloses a technique for publishing conference material only when it is included in access permitted person information set in advance by the user of the conference host terminal.

Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings. The configurations shown in the following embodiments are merely examples, and the present invention is not limited to the illustrated configurations.
In the following embodiments, description is made on the premise of SMB (Server Message Block) as a protocol for realizing file sharing. However, the application destination of the present invention is not limited to SMB, and can be applied to all file sharing protocols via a network such as NFS (Network File System).

<First Embodiment>
FIG. 4 shows a system configuration example of the present embodiment. The conference material sharing system according to the present embodiment includes a material registration terminal 1, a conference server 2, and a conference hosting terminal 3. The conference material is created as an electronic document and distributed to conference participants. There may be a plurality of document registration terminals 1 and conference holding terminals 3. Further, the function of the conference server 2 may be included in the material registration terminal 1 or the conference holding terminal 3 so as to have a peer-to-peer (P2P) configuration. The document registration terminal 1, the conference server 2, and the conference host terminal 3 are connected by a wired or wireless network.

Since the material registration terminal 1, the conference server 2, and the conference holding terminal 3 have the same hardware configuration, the material registration terminal 1 will be described in detail.
The UI device 101 is a mouse, a digitizer, a keyboard, or the like, and is used to input a user instruction to the material registration terminal 1. The CPU 102 and the RAM 103 exist, and various controls and calculations in the apparatus and UI display are possible by the CPU 102 interpreting and executing a program read from the program storage area 106 to the RAM 103.

  The communication IF 104 is connected to the network 4 and is a communication interface with the conference server 2 and the conference host terminal 3. The UI display unit 105 is an LED, a liquid crystal panel, or the like that displays the state of the apparatus and processing contents. Further, a program storage area 106 and a data storage area 107 exist. Specifically, these storage areas can be realized using a hard disk or a flash memory, but the present invention does not depend on a specific storage medium.

  In the material registration terminal 1, the conference material 10 is stored in the data storage area 107. In the conference server 2, the material registration information 20 and the conference information 21 are stored in the data storage area 207. An example of the material registration information is shown in FIG. 8, and an example of the meeting information is shown in FIG.

  Next, the operation at the time of conference material registration of the conference material sharing system will be described using the system configuration diagram of FIG. 1 and the sequence diagram of FIG. Here, a description will be given of a use case example in which a material registrant (Mr. A) operates the material registration terminal 1 (PC name: PC1) to register material X (registered material) in a conference M prepared in advance.

First, when Mr. A logs in at T101, a login request is made to the conference server 2 at T102. If the user authentication is successful, the login is successful at T103, and the material registration terminal 1 can be used.
Next, when Mr. A opens the conference M at T104, the conference server 2 is requested to open the conference M at T105. If Mr. A has an access right to the conference M, it becomes open OK at T106, and the operation to the conference M becomes possible.

  Next, when Mr. A performs the registration work of the material X at T107, a request to register the material X is made to the conference server 2 at T108, and the material registration information is generated and stored at T109. In this use case example, material registration information as shown in FIG. 8A is generated. That is, the material registration terminal is PC1, the material registrant is Mr. A, the registration destination conference is conference M, and the registered material path is "C: \ conference material \ document X.txt". If the material is normally registered, the registration is OK at T110, and the registration work is completed.

When the registration work is completed and Mr. A closes the conference M at T111, the conference server 2 is requested to close the conference M at T112, and when the closing process is completed, the close is OK at T113.
Finally, when Mr. A logs out at T114, a logout request is made to the conference server 2 at T115. When the logout processing is completed, the logout is OK at T116, and the operation at the material registration terminal 1 is completed.

  Next, the operation of the conference material sharing system when referring to the conference material will be described using the system configuration diagram of FIG. 2, the sequence diagram of FIG. 6, and the conference screen UI example of FIG. Here, a use case example will be described in which a material registrant (Mr. A) operates the conference holding terminal 3 (PC name: PC3) to refer to the material X on the material registration terminal 1 (PC name: PC1). . It should be noted that operations other than referring to the material X are performed by the meeting organizer (Mr. B).

First, when Mr. B logs in at T201, a login request is made to the conference server 2 at T202. If the user authentication is successful, the login is OK at T203, and the conference host 3 can be used.
Next, when Mr. B starts the conference M at T204, the conference server 2 is requested to start the conference M at T205. If Mr. B has an access right to the conference M, the start is OK at T206, and the operation to the conference M and the progress of the conference are possible.

  Next, the fact that Mr. A has attended the meeting M at T207 is notified by a check box in the participant list 1091 on the meeting screen 1090 displayed on the UI display unit 305 of the meeting holding terminal 3. In order to confirm attendance without fail, an ID card reader may be attached to the conference terminal 3 and an ID card such as an employee ID card held by Mr. A may be held over. At T208, a request for attendance of Mr. A to the conference M is made to the conference server 2, and if Mr. A is included in the list of attendees, attendance OK is returned at T209. As shown in FIG. 14, Mr. A is recorded as the actual attendee in the conference information.

Next, Mr. A refers to the document X at T210, that is, opens “document X.txt” in the file list 1092 on the conference screen 1090 by double-clicking. At T211, the conference server 2 is requested to refer to the material X, and at T212, the disclosure determination process shown in FIG. 12 is performed.
When the disclosure determination process is started in S1200, it is determined in S1201 based on the material registration information 20 and the conference information 21 whether the currently held conference is a conference opened by Mr. A when the material is registered. In S1202, it is determined based on the material registration information 20 and the conference information 21 whether or not the material registrant (Mr. A) is attending the conference currently being held. If both S1201 and S1202 are “Yes”, that is, if the meeting being held matches the registration destination meeting, and the document registrant is present at the meeting being held, permission to release the document in S1203 To do. If either one is “No”, the publication of the material is not permitted in S1204.

  If it is determined that the publication is permitted at T212, a publication request for the material X is sent to the material registration terminal 1 at T213, the file is shared at T214, and the material is published. In the present embodiment, the disclosure determination is performed by the conference server 2, but may be performed by the material registration terminal 1 as long as the material registration information 20 and the conference information 21 are accessible. Further, when the material registration terminal 1 is stopped, it may be activated by Wake-On-LAN (WOL).

  In general, since file sharing restricts whether or not sharing is possible on a folder basis, in this embodiment, a hard link of a file system is used as shown in FIG. 9 in order to realize sharing restrictions on a file basis. . In an environment in which whether or not file unit sharing can be set, the file 1072 may be directly shared without using a hard link.

  Specifically, instead of making the conference material folder 1071 directly shareable, a shared folder 1074 having a name combining the drive name and the conference name is created under the public folder 1073. The UNC (Universal Naming Convention) of the shared folder 1074 is a shared path 1077.

  Since hard links cannot be created across drives, it is possible to create a shared folder for the target conference for each drive by adding the drive name to the shared folder name. Under the shared folder 1074, a folder 1075 and a file 1076 are generated with the same hierarchical structure as the actual path of the conference material. However, the entity of the file 1076 points to the file 1072 by the hard link 1079. Therefore, it is not necessary to actually copy the file 1072 in order to generate the file 1076 for sharing. The UNC of the sharing file 1076 is a sharing path 1078.

  When the document publishing process ends normally, this shared path 1078 is transferred to the conference server 2 together with the T215 public OK response, and as shown in FIG. Is written to. Further, it is passed to the conference holding terminal 3 together with the reference OK response of T216, and is used for reading and writing to the material X starting from T217.

  When the conference ends, Mr. B, who is the conference organizer, ends the conference M at T220. A request to end the conference M is sent to the server 2 at T221, and a non-disclosure request for the material X is sent to the material registration terminal 1 at T222. If there is a document that has been released in addition to the document X, a non-disclosure request is also sent to them.

In the material non-disclosure process of T223, the hard link 1079 and the hard link source file 1076 are deleted in FIG. When the document non-disclosure processing is completed, a response of non-disclosure OK is returned to the conference server 2 at T224, and an end OK response is returned to the conference host terminal 3 at T225.
Thereafter, when Mr. B logs out at T226, the use of the conference terminal 3 is terminated.

<Second Embodiment>
As another embodiment related to the present invention, after referring to the material X in T210 of FIG. 6, the material in the same folder as the material X or a file in a lower folder may be registered. More specifically, a material registration dialog 1083 as shown in FIG. 10 is displayed on the conference host terminal 3 and an additional material registration process for adding a material Y in the same folder as the material X and a file in the lower folder 1081 is executed.

  In this dialog, the folder hierarchy is displayed in the left pane, and the focus frame is applied to the conference material folder 1071 that is currently the reference target. A list of files in the reference folder is displayed in the right pane. Since the folder 1070 and the folder 1082 are not subordinate to the folder of the document X, the focus cannot be moved.

  In FIG. 10, these folders are displayed in gray, but they may not be displayed. On the other hand, since the folder 1081 is located below the folder with the document X, the focus can be moved. For example, when it is desired to publish material Y as material supplementing material X, material registration is completed by selecting file 1080 and pressing registration button 1084.

<Third Embodiment>
As another embodiment relating to the present invention, it is also possible to refer to materials from a conference host terminal at another site that has opened a desktop screen as shown in the system configuration diagram of FIG.
The operation when referring to the conference material from another site of the conference material sharing system will be described with reference to the system configuration diagram of FIG. 3 and the sequence diagram of FIG. In FIG. 7, the response portion of each sequence that can be understood from the description of FIG. 6 is omitted.

  Here, a description will be given of a use case example in which a conference host 5 (PC name: PC5) at another base is operated by a participant (Mr. C) other than the document registrant to refer to the document X on the document registration terminal 1. To do. In addition, Mr. A and Mr. B operate the conference holding terminal 3 to perform attendance notification to the conference and start / end of the conference.

  First, Mr. B logs in at T301, makes the conference host terminal 3 available, starts the conference M at T303, and enables operations to the conference M and the progress of the conference. And it notifies that Mr. A attended the meeting M at T305.

  Next, Mr. C logs in by operating the conference holding terminal 5 at T307 and participates in the conference M at T309. At this time, by setting the entire desktop area of the PC 5 to share the screen, the desktop screen of the PC 5 is opened to the PC 3 as shown in FIG.

  Next, Mr. C refers to the material X at T311. At T312, a request for reference to the material X is made to the conference server 2, and at T313, the disclosure determination process shown in FIG. 13 is performed. The disclosure determination processes S1301 and S1302 are the same as S1201 and S1202 in FIG. 12, respectively.

In S1303, based on the material registration information 20 and the conference information 21, it is determined whether or not the screens of other sites where the material is to be referred to are shared and disclosed to the local site where the material registrant (Mr. A) is present. Judgment. When S1301, S1302, and S1303 are all “Yes”, disclosure of the material is permitted in S1304. If any one is “No”, the publication of the material is not permitted in S1305.
When it is determined that the publication is permitted at T313, a publication request for the material X is sent to the material registration terminal 1 at T314, the file is shared, and the material is published. Since the operation from T315 to T328 is the same as the operation described with reference to FIG.
