The present invention relates to an electronic conference method, an electronic conference system, an electronic file management server, and an information terminal.

Background art

[0002] In recent years, with the high performance and high functionality of computers and the spread of networks, computers used by conference participants themselves without using expensive dedicated conference equipment installed at specific locations were used. It has become possible to hold cheaper electronic conferences that are not limited to places.

[0003] In a conference using an information terminal such as a computer, an electronic conference is generally realized by the following procedure.

[0004] Step 1. The meeting organizer performs connection setting and opening of the communication path used in the meeting at his information terminal.

[0005] Step 2. The conference organizer notifies the conference participants of the connection settings for the previously opened communication path.

[0006] Step 3. The conference participant connects to the communication path based on the notified connection setting at his / her information terminal.

[0007] Step 4. The conference organizer and conference participant information terminals transmit and receive conference data using the communication path.

[0008] Step 5. The meeting organizer closes the communication path at his information terminal.

[0009] In the above procedure, steps 1 to 3 are procedures for establishing a communication path connecting the conference organizer and the conference participant's information terminal. Information used for connection setting includes the conference organizer The IP address of the information terminal you have, the communication port number used for the conference, In addition, encryption methods and encryption key settings to avoid interception of communications by third parties are included.

[0010] In addition, step 3 is a procedure for realizing communication between participants during the conference. As data to be transmitted / received, conference participants made up of video, audio and electronic files of conference participants, etc. Is included. Step 4 is a procedure for releasing the communication path, which means the end of the conference.

Disclosure of the invention

Problems to be solved by the invention

[0012] According to the procedures in steps 1 to 5 above, the conference participants can connect to individual information terminals via the network using their own information terminals that use expensive dedicated conference devices. Since it is possible to participate in any place power conference, it is possible to realize an electronic conference more inexpensively and flexibly than when using a dedicated conference device.

[0013] On the other hand, the IP address, communication port number, encryption key, etc. in the connection settings are numerical values or meaningless character strings that are difficult for human beings, and are accurately set to appropriate values each time a conference is held. The setting work required a lot of time and effort before the start of the conference, causing stress to participants and causing the risk of information leakage due to setting errors.

[0014] In recent years, various documents including important documents have been digitized to improve the efficiency and convenience of work related to document creation. On the other hand, however, there are concerns about the danger of unintentional document modification and information leakage due to the ease of editing and copying, which are the characteristics of electronic files.

[0015] In general companies and organizations, an electronic file management server capable of strictly managing access rights to electronic files has been introduced as a defense against such concerns. An electronic file management server generally grants access rights to users for each electronic file. For example, for a specific file, a certain user is given only a reference right and another user is given an update right.

[0016] When an electronic conference is held using an electronic file managed by the electronic file management server as a meeting material, a user who has a reference right to the electronic file from the electronic file management server prior to the conference The first method of acquiring an electronic file on the information terminal owned by itself, establishing the communication channel for the conference, and transmitting the electronic file data to the communication channel for distribution to the conference participants, or the conference communication There is a second method in which each participant can access the electronic file management server and obtain the electronic file without using the route.

[0017] However, at present, there is no mechanism for coordinating with the electronic file management server in the conference implementation procedure. Therefore, in the first method, when the user acquires an electronic file as an electronic file management server, If the access control of the electronic file management server is out of control and the access control is continued for the electronic file, the electronic file is sent before the electronic file is sent to the communication path. It will be necessary to set access rights separately.

[0018] Regardless of whether or not the distributor of the material intends to do so, the electronic file management server does not permit the reference, and does not permit the user to distribute or update the material, but the user has the right to update the material. This is a security issue for document management in companies and organizations.

[0019] On the other hand, when each participant individually obtains the conference material by the second method, the electronic file data of the conference material cannot be synchronized between the participants, and therefore updated during the conference. The contents cannot be confirmed in real time. Therefore, in order for the participants to confirm the changes to the materials that occurred during the conference, the participants'! When either of the participants updates the electronic file of the electronic file management server and notifies each participant that the update is complete, and when the participant who receives the notification individually accesses the electronic file management server and confirms the update contents, This is a factor that reduces the convenience of electronic conferencing. [0020] The present invention has been made in view of the above points, and an electronic conferencing method and an electronic conferencing method that do not require setting of access rights for conference materials that do not need to be set for connection of a conference communication path. The overall purpose is to provide a conference system, an electronic file management server, and an information terminal.

Means for solving the problem

[0021] In order to achieve this object, the electronic conferencing method of the present invention manages an electronic file of a conference material with an electronic file management server connected to a network, and manages the electronic file with a plurality of information terminals via the network. An electronic conferencing method in which an electronic conference is performed by connecting to a server, and an electronic file and access right information of a conference material are set in the electronic file management server in response to a request for information terminal capability setting, and the conference of the organizer's information terminal capability The electronic file management server generates connection information for establishing a communication channel for the meeting in response to a holding request, and the connection information is sent from the electronic file management server to the participant in response to the meeting participation request of the participant's information terminal capability. The information terminal of the participant connects to the communication channel for the conference based on the distributed connection information.

The invention's effect

[0022] According to such an electronic conferencing method, it is possible to improve convenience in an electronic conference in which it is not necessary to set the access right of the conference material independently, which does not require the connection setting of the communication channel for the conference. Can do.
