  Next, an operation flow and screen transition when authenticating the guest user A will be described with reference to FIGS.

  First, when the IWB 200 itself does not use the online conference space and is used as a mere IWB, as shown in “IWB screen example 1-1” in FIG. 7, an application screen 7001 including a code in a part of the screen 7000 of the IWB 200. Is displayed.

  The code is shown here as a QR code, but the present embodiment is not limited to this. As will be described later, the conference terminal 100 acquires a URI indicating the location of the online conference space by capturing the code with the conference terminal 100. The code changes depending on the conference setting. In addition to the URI, data in the conference registration information table in FIG. 5, for example, information such as the conference opening time may be acquired.

  Below the code, a password corresponding to the online conference space used in the conference is displayed. This password is displayed as an image and changes periodically.

  When the IWB 200 itself also uses the online conference space, an online conference application screen 7002 is displayed on the screen 7000 of the IWB 200, as shown in “IWB screen example 1-2” in FIG.

  A code and password of the same type as the code and password shown in FIG. 7 are displayed in the upper left part of the application screen 7002.

  A space for uploading a file is displayed in the lower left portion of the application screen 7002. By dragging and dropping a file to be stored in the storage medium of the IWB 200 into this space, it is possible to upload the file to the online conference space.

  Displayed in the upper right part of the application screen 7002 is a button for logging in to the online conference space. The character string displayed at the bottom of the button is an ID of the online conference space and a unique address in the conference server 300-1 as a URI.

  What is displayed in the lower right part of the application screen 7002 is a file used in a meeting to be implemented.

  The guest user A and the registered user B described in FIG. 1 capture the code illustrated in FIG. 7 or FIG. 8 by using the image capturing unit included in each of the conference terminals 100-1 and 1002, thereby providing a conference system. 10. As a result, login to the online conference space of the conference system 10 is attempted.

  Here, since the registered user B has already been registered in the conference system 10, it is possible to log in to the conference system 10, and thus to the online conference space. However, for the guest user A, in the connection request to the conference server 30 generated by decoding the code to be photographed, as described in the description using the sequence diagram shown in FIG. There is no authentication token unique to the conference terminal 100-1. Therefore, at this stage, the conference server 300-1 cannot authenticate the guest user A. Therefore, the conference server 300 displays the application screen 7003 shown in the upper part of FIG. 9 on the conference terminal 100-1.

  Here, displayed in the upper left part of the application screen 7003 are columns of a user name, a device name, an e-mail address, and a password in order from the top. Guest user A inputs his user name, the device name of conference terminal 100-1 and the password in these fields. The password is a password displayed as an image on the application screen 7001 in FIG. 7 or the application screen 7002 in FIG.

  Also, what is shown in the lower left part of the application screen 7003 is a user ID and a device ID in order from the top. These are already applied when the conference terminal 100-1 displays the application screen 7003 in accordance with an instruction from the conference server 300-1.

  Also, a button for inquiring login to the online conference space is displayed in the upper right part of the application screen 7003. The character string displayed at the bottom of the button is an ID of the online conference space and a unique address in the conference server 300-1 as a URI.

  Also, a check box for requesting authentication by another user is displayed in the lower right part of the application screen 7003.

  When the guest user A requests authentication of himself / herself, the check box is checked and the button is clicked. Then, an application screen 5004 shown in the lower part of FIG. 9 is displayed. In this application screen 7004, an authentication request is transmitted to the conference server 300-1, indicating that an inquiry is being made.

  When the conference server 300-1 receives the authentication request from the conference terminal 100-1, the conference server 300-1 requests the conference terminal 100-2 used by the registered user B for authentication. At this time, the application screen 7005 of FIG. 10 is displayed on the conference terminal 100-2 as a screen for performing the authentication process of the guest user A.

  In the application screen 7005, displayed in the upper left part are the user name, device name, and password fields of the registered user B in order from the top. At the stage where the registered user B authenticates the guest user A, the user name and device name are already automatically filled with data, and the registered user B enters the password in the password field. In addition, a fingerprint image is displayed on the right side of these columns. This is a column used when the registered user B performs biometric authentication as the authentication. The password field and the fingerprint stamp field may include both or only one of them.

  In the lower left part of the application screen 7005, the user name, device name, e-mail address, user ID, and user ID of the guest user A and the conference terminal 100-1 used by the guest user A are displayed in order from the top. Device ID. These data are data received from the conference server 300-1, and have already been applied when the application screen 7005 is displayed. In addition, on the right side of these columns, “CHK-OK” is displayed. As described in the description using the sequence diagram of FIG. 13 to be described later, this display is simply described as an authentication check result by a challenge-response between the conference terminal 100-1 and the conference server 300-1. Indicates that was OK. Specifically, a challenge that is a random number sequence is transmitted from the conference server 300-1 to the conference terminal 100-1, and after the conference terminal 100-1 generates an authentication token based on the challenge and the calculation formula, When the authentication token is sent back to the conference server 300-1 as a response, it indicates that the result of checking the response by the conference server 300-1 is OK.

  In the upper right part of the application screen 7005, it is displayed that the online conference application used by the registered user B is in the guest user (unregistered user) authentication stage.

  In the lower right portion of the application screen 7005, the URI of the online conference space is displayed, and further below that, a button for selecting whether or not to approve the registration of the guest user A is displayed. The button displayed on the left is a button for approving registration, and the button displayed on the right is a button for rejecting registration. Regardless of which button is clicked, a screen displaying that the transmission of the authentication result is completed is displayed as an application screen 7006 as shown on the right side.

  When the registered user B clicks the button for approving the registration of the guest user A on the application screen 7005 in FIG. 10, the screen transition of the online conference application on the conference terminal 100-1 used by the guest user A is as follows. As shown in FIG.

  As shown in FIG. 9, while the guest user A is waiting for authentication, an application screen 7004 indicating that the user is currently inquiring is displayed.

  Thereafter, upon receiving registration approval by the registered user B, an application screen 7007 indicating that the user registration of the guest user A has been authenticated is displayed.

  When the guest user A clicks an OK button on the application screen 7007, an application screen 7008 after logging in to the conference system 10 is displayed on the display unit of the conference terminal 100-1.

  The user name, provisional password, and device name columns of guest user A are displayed in the upper left part of the application screen 7008. When the application screen 7008 is displayed, these columns are already filled with data. ing.

  Other elements in the application screen 7008 are the same as those in the application screen 7002 shown in FIG.

  The guest user A can log in to the online conference space having a URI written in the lower part by clicking a button displayed in the upper right part of the application screen 7008.

  FIG. 10 shows a screen transition of the authentication application in the conference terminal 100-1 used by the guest user A when the registered user B clicks the button for rejecting the registration of the guest user A on the application screen 7005 in FIG. 12 shows.

  As shown in FIG. 9, while the guest user A is waiting for authentication, an application screen 7004 indicating that the user is currently inquiring is displayed.

  Thereafter, in response to registration refusal by the registered user B, an application screen 7009 indicating that the user registration of the guest user A has been rejected is displayed.

  The operation flow and screen transition when authenticating the guest user according to the first embodiment are as described above.

  Next, according to the above flow, the conference terminals 100-1 and 100-2 and the conference server 300-1 when the temporary registration of the guest user A in the conference system 10 is authenticated by multi-factor authentication. Inter-parameter transmission / reception will be described with reference to the sequence diagram of FIG.

  First, as shown in step S2001, the guest user A images the code displayed on the screen of the IWB 200 using the conference terminal 100-1.

  Next, as shown in step S2002, the conference terminal 100-1 decodes the captured code.

  Next, as shown in step S2003, the conference terminal 100-1 requests connection to the conference server 300-1 in order to access the online conference space corresponding to the URI included in the decoding result.

  When the connection is requested, as shown in step S2004, the online conference space ID “cid” and the time stamp “timestamp” at the time of the connection request are transmitted to the conference server 300-1. In FIG. 13, “(uid (A))”, “(did (A))”, and “(token)” are also described, and these indicate that user A is a registered user. It is transmitted when it is assumed. However, in the sequence shown in FIG. 13, user A is a guest user and is not transmitted. “Uid” is a user ID, “did” is a device ID, and “token” is an authentication token unique to the device.

  Next, as shown in step S2005, the conference server 300-1 performs a “cid” check and a user check. At this time, since the guest user A is not a registered user, there is no authentication token. Therefore, in order to obtain an authentication token in a response in 8 to be described later, “challenge” that is a random number sequence is generated from the conference terminal 100-1. At the same time, a temporary uid (“uid (A)”) and a temporary did (“did (A)”) for the guest user A are issued.

  Next, as shown in step S 2006, the conference server 300-1 sends an information registration request to the conference terminal 100-1 and the newly generated “challenge”, “uid (A)”, “did (A)”. ".

  Next, as shown in step S2007, the conference terminal 100-1 requests connection again from the conference server 300-1.

  At the time of re-request for connection, as shown in step S2008, the conference terminal 100-1 adds “tokenA” in addition to “cid”, “uid (A)”, “did (A)”, and “timestamp”. "And" entryinfoA "are transmitted to the conference server 300-1. (In this specification, “cid” may be referred to as “temporal and spatial information” and “entryinfo A” may be referred to as “user information of guest user A”.) Here, “tokenA” refers to the conference server 300- 1 is an authentication token calculated from “challenge” transmitted from 1 to the conference terminal 100-1 and a password input by the guest user A on the conference terminal 100-1 based on the display on the IWB 200. And included in the response to “challenge”. “EntryinfoA” is entry information input from the conference terminal 100-1 by the guest user A.

  Next, as shown in step S2009, the conference server 300-1 performs a “cid” check, a user check, and a “tokenA” check. If there is no problem with these checks, “uid (B)” corresponding to the registered user B is selected from the uid of the registered user as a terminal for authenticating the guest user A. Furthermore, “challenge_b” which is a random number sequence is generated from the unique information of the registered user B. This is to obtain an authentication token in the response from the conference terminal 100-2 used by the registered user B in step 13 described later. The unique information of the registered user B is shared between the conference server 300-1 and the conference terminal 100-2.

  Next, as shown in step S2010, the conference server 300-1 sends the above-mentioned “cid”, “uid (A)”, “did (A)”, “ In addition to “timestamp”, “entryinfoA”, “uid (B)”, and “charge_b”, “did (B)” and “timestampB” are transmitted. Here, “did (B)” is “uid (B)”, that is, a device ID corresponding to the conference terminal 100-2 used by the registered user B. “TimestampB” is a time stamp at the time when the authentication request is sent from the conference server 300-1 to the conference terminal 100-2.

  Next, as shown in step S <b> 2011, the conference terminal 100-2 receives the authentication request from the conference server 300-1, and simultaneously displays the “entryinfoA” information on the display unit. Accordingly, the conference terminal 100-2 presents the entry information input by the guest user A on the conference terminal 100-1 to the registered user B.

  Next, as shown in step S2012, the registered user B registers the guest user A on the conference terminal 100-2. That is, the registered user B selects whether or not to allow the guest user A to use the conference system 10. At this time, as described above, the registered user B may perform password authentication by inputting a password to the conference terminal 100-2, or may perform biometric authentication by inputting a fingerprint or the like.

  Next, as shown in step S2013, the conference terminal 100-2 makes the above “cid”, “uid (A)”, “did (A)”, “timestamp”, “timestamp” to the conference server 300-1. In addition to “uid (B)”, “did (B)”, and “timestampB”, “tokenB” and “auth_infoB” are transmitted. Here, “tokenB” is an authentication token calculated from “challenge_b” transmitted from the conference server 300-1 to the conference terminal 100-2 and the unique information of the registered user B, and “challenge_b”. Included in the response to. “Auth_infoB” is use permission information (OK / Rejected) of the guest user A by the registered user B.

  Next, as shown in step S2014, the conference server 300-1 checks “tokenB”, and if there is no problem, the usage permission information by the registered user B is reflected. When the registered user B permits the guest user A to use the conference system 10, the guest user A is registered as a temporary regular user. That is, “uid (A)” and “did (A)” which are temporary IDs as described above temporarily become regular IDs. At this time, two or more of “did (B)”, which is identification information of the conference terminal 100-2, a password corresponding to itself input by the registered user B, and fingerprint information of the registered user B are used. Thus, after performing multi-factor authentication of the registered user B, the use permission information by the registered user B may be reflected.

  Next, as shown in step S2015, the above-mentioned “cid”, “uid (A)”, “did (A)”, “timestamp”, “timestamp”, “ In addition to “uid (B)”, “did (B)”, and “timestampB”, “auth_result” and “password_tmp” are transmitted. Here, “auth_result” is use permission information for the guest user A by the conference system 10. “Password_tmp” is a password temporarily used when the guest user A uses the conference system 10.

  Finally, as shown in step S <b> 2016, the conference terminal 100-1 receives the use permission result from the conference server 300-1, and “uid (A)” associated with “cid” is the uid registered as regular. Be treated.

  In the above sequence, two types of time stamps “timestamp” and “timestampB” are transmitted and received. These time stamps may be used as information for determining whether or not to authenticate the guest user A by comparing with the time when the conference is held. Further, by using both time stamps, time synchronization type authentication may be performed between the respective subjects.

  The code displayed on the screen of the IWB 200 is displayed by the conference server 300-1, that is, the code generated by the conference server 300-1 and transmitted from the conference server 300-1 to the IWB 200. However, the IWB 200 itself may generate, input or select.

  In the above description, the user information manually input from the application screen 7003 displayed on the conference terminal 100-1 is described as the user information of the guest user A. However, the conference terminal 100-1 may be provided with a holding unit that is used in place of the input unit 102 or together with the input unit 102 and includes user information of the guest user A. Thereby, for example, user information held in advance by the conference terminal 100-1 can be used.

  In addition, as described above, there may be a plurality of registered users. At that time, the registered user for whom the conference server 300-1 requests the authentication of the guest user A is selected at random from the plurality of registered users. Alternatively, it may be a registered user closest to the guest user A in distance (that is, a registered user who is a user of the conference terminal 100-2 closest to the conference terminal 100-1). Thereby, for example, it is possible to prevent the registered user B from illegally authenticating the guest user A when both the guest user A and the registered user B communicate with each other in a malicious manner.

According to the present embodiment, when an online conference is held by a plurality of people, the security of the online conference system is ensured by using the multi-factor authentication process with the resources of registered users of the online conference system interposed. This makes it possible to easily use the online conference service.
<Second Embodiment>
Next, a second embodiment will be described with reference to FIGS.

  FIG. 14 is a diagram showing an outline of a configuration and usage method of the conference system 20 according to the second embodiment of the present invention. In the conference room, there are two conference terminals 100-3 and 100-4 and a conference server 300-2 that can communicate with each other through a router such as a Wi-Fi router. The conference terminal 100-3 is a terminal used by a user who has not been registered with the conference system 20 (hereinafter also referred to as “guest user C”). The conference terminal 100-4 is a terminal used by a user who has already been registered with the conference system 20 (hereinafter also referred to as “registered user D”). Here, for simplification of explanation, only two terminals, the conference terminal 100-3 and the conference terminal 100-4, are illustrated as conference terminals, but the embodiment of the present invention is not limited to this. There may be three or more conference terminals.

  Note that the conference terminal 100-3, the conference terminal 100-4, and the conference server 300-2 may be connected by wire or may be connected wirelessly.

  Here, even if the guest user C tries to use the conference system 20 using the conference terminal 100-3, the guest user C is not registered with the conference system 20 and cannot use the conference system 20. Therefore, the guest user C is registered in the conference system 20 by the following method.

  First, as shown in FIG. 14, the conference server 300-2 displays a code (for example, QR code) on the display unit of the conference terminal 100-4. After the code is displayed, the guest user C images the code using an imaging unit such as a small camera built in the conference terminal 100-3 (step S3001).

  Next, as shown in FIG. 14, the conference terminal 100-3 obtains the user information of the guest user C who uses the conference terminal 100-3 based on the decoding result after imaging the code. -2 (step S3002).

  Next, as shown in FIG. 14, the conference server 300-2 transmits an instruction for requesting authentication of the guest user C to the conference terminal 100-4 used by the registered user D (step S3003).

  Finally, the registered user D performs an authentication operation on the conference terminal 100-4, and the guest user C is registered in the conference system 20 as a temporary registered user C during the conference held in the conference room. The conference system 20 can be used (step S3004).

  The configuration of the conference terminals 100-3 and 100-4 is the same as that of the conference terminal 100 shown in FIG. The configuration of the conference server 300-2 is the same as that of the conference server 300-1 shown in FIG.

  Next, an operation flow and screen transition when authenticating the guest user C will be described with reference to FIGS.

  First, when a registered user D who has already registered in the conference system 20 logs in to the conference system 20 with the conference terminal 100-4, the conference application shown in FIG. 15 is displayed on the display unit of the conference terminal 100-4. The application screen 8001 is displayed.

  Displayed in the upper left part of the application screen 8001 is a code necessary for authentication of registration in the conference system 20. As will be described later, the guest user C starts the registration procedure in the conference system 20 by imaging this code by imaging means such as a small camera built in the conference terminal 100-3.

  Displayed in the upper middle part of the application screen 8001 are the user name of the registered user D, the device name, and the password necessary for the registration of the guest user C in the conference system 20 in order from the top. This password is displayed as an image and changes periodically.

  Subsequently, the guest user C images the code in the application screen 6001 displayed on the registered user's conference terminal 100-4 with an imaging unit such as a small camera built in the conference terminal 100-3. The conference terminal 100-3 acquires a URI indicating the location of the online conference space. The code changes depending on the conference setting. In addition to the URI, data in the conference registration information table in FIG. 5, for example, information such as the conference opening time may be acquired. At the same time, as shown in the upper part of FIG. 16, an application screen 8002 is displayed on the conference terminal 100-3.

  Since the screen configuration of the application screen 8002 is the same as that of the application screen 7003 shown in FIG. 9 according to the first embodiment, the description thereof is omitted.

  The guest user C inputs his / her user name, the device name of the conference terminal 100-3, and the password displayed as an image on the conference terminal 100-4 in the corresponding fields, and checks the check box. And click the button to inquire about logging into the online meeting space. Then, an application screen 8003 shown in the lower right part of FIG. 16 is displayed. In this application screen 6003, an authentication request is transmitted to the conference terminal 100-4 used by the registered user D to indicate that an inquiry is being made.

  Upon receiving the above authentication request from the conference terminal 100-3, the conference terminal 100-4 displays an application screen 8004 shown in the lower left part of FIG.

  Since the screen configuration of the application screen 8004 is the same as that of the application screen 7005 shown in FIG. 10 according to the first embodiment, the description thereof is omitted.

  The registered user D performs password authentication and / or fingerprint authentication and clicks a button for selecting whether or not to approve registration of the guest user C.

  Then, on the display unit of the conference terminal 100-4, as shown in the lower left part of FIG. 17, a screen displaying that the transmission of the authentication result is completed is displayed as the application screen 8005.

  Further, when the registered user D approves the registration of the guest user C, the display unit of the conference terminal 100-3 indicates that the registration of the guest user C is authenticated as shown in the upper right part of FIG. An application screen 8006 is displayed.

  Thereafter, when the guest user C clicks an OK button on the application screen 8006, an application screen 8007 after logging in to the conference system 20 is displayed on the display unit of the conference terminal 100-3.

  The screen configuration of the application screen 8007 is the same as that of the application screen 8001 except that a message indicating that it is after authentication is displayed at the top, and thus the description thereof is omitted.

  The operation flow and screen transition when authenticating a guest user according to the second embodiment are as described above.

  Next, according to the above flow, the terminals 100-3 and 100-4 for conference and the conference server 300-2 when the temporary registration of the guest user C in the conference system 20 is authenticated by multi-factor authentication. Inter-parameter transmission / reception will be described with reference to the sequence diagram of FIG.

  First, as shown in step S4001, the guest user C images the code displayed on the display unit of the registered user D using the conference terminal 100-3.

  Next, as shown in step S4002, the conference terminal 100-3 decodes the captured code.

  Next, as shown in step S4003, the conference terminal 100-3 requests connection to the conference server 300-2 in order to request the registered user D to authenticate registration with the conference system 20.

  At the time of the connection request, as shown in step S4004, the online conference space ID “cid”, the registered user D ID “uid (D)”, and the time stamp “timestamp” at the time of the connection request are entered. It transmits to the conference server 300-2. Note that “uid (D)” is obtained at the time of decoding. In FIG. 18, “(uid (C))”, “(did (C))”, and “token” are also described. It is assumed that user C is a registered user. Is sent in case. However, in the sequence shown in FIG. 18, user C is not transmitted because it is a guest user. As in the first embodiment, “uid” is a user ID, “did” is a device ID, and “token” is an authentication token unique to the device.

  Next, as shown in step S4005, the conference server 300-2 performs a “cid” check and a user check. At this time, it is confirmed that the registered user D is logged in to the conference system 20, and if it can be confirmed, it is determined to make a request to issue a challenge to the conference terminal 100-4 of the registered user D.

  Next, as shown in step S4006, the conference server 300-2 transmits a challenge issue request to the conference terminal 100-4 of the registered user D.

  Next, as shown in step S4007, the conference terminal 100-4 generates “challenge_dC” to be used between the conference terminal 100-4 and the conference terminal 100-3 based on the unique information of the registered user D. To do. This “challenge_dC” is also a time stamp (= “timestamp_dC”) when the conference server 300 requests the conference terminal 100-4 to issue a challenge.

  Next, as shown in step S4008, the conference terminal 100-4 transmits the generated “challenge_dC” to the conference server 300-2.

  Next, as shown in step S4009, the conference server 300-2 transfers the received “challenge_dC” to the conference terminal 100-3, and the temporary uid (“uid (C)”) for the guest user C and the temporary uid. issue id ("did (C)").

  Next, as shown in step S4010, the conference server 300-2 sends an information registration request to the conference terminal 100-3, and the above “cid”, “uid (C)”, “did (C)”, In addition to “uid (D)” and “challenge_dC”, “did (D)” which is the device ID of the conference terminal 100-4 is transmitted.

  Next, as shown in step S4011, the conference terminal 100-3 requests authentication from the conference terminal 100-4.

  At the time of requesting authentication, as shown in step S4012, the conference terminal 100-3 sends the above “cid”, “uid (C)”, “did (C)”, “uid (D)”, “did ( In addition to “D)” and “challenge_dC”, “token_dC”, “entryinfoC”, and “timestampC” are transmitted to the conference terminal 100-4. (In this specification, “cid” is sometimes referred to as “temporal and spatial information”, and “entryinfoC” is sometimes referred to as “user information of guest user C”.) Specifically, these parameters are referred to as conference server 300-. 2, the conference server 300-2 transfers these parameters to the conference terminal 100-4. Here, “token_dC” refers to “challenge_dC” transmitted from the conference server 100-4 to the conference terminal 100-3 and the display by the guest user C on the conference terminal 100-4 based on the display on the conference terminal 100-4. 3 is an authentication token that is calculated from the password entered above, and is included in the response to “challenge_dC”. “EntryinfoC” is entry information input from the conference terminal 100-3 by the guest user C. “TimestampC” is a time stamp when a connection is requested from the conference terminal 100-3 to the conference terminal 100-4.

  Next, as shown in step S4013, the conference terminal 100-4 performs matching of “token_bA” received from the conference terminal 100-3, and if there is no problem, uses “challenge_bA” (= “timestamp_bA”). Determine and set the validity period. Thereafter, the registered user D performs registration authentication of the guest user C on the conference terminal 100-4. That is, the registered user D selects whether or not to permit temporary use of the conference system 20 of the guest user C. At this time, two or more of “did (D)”, which is identification information of the conference terminal 100-4, a password corresponding to itself input by the registered user D, and fingerprint information of the registered user D are used. Thus, after performing multi-factor authentication of the registered user D, registration authentication by the registered user D may be performed.

  Next, as shown in step S4014, the conference terminal 100-4 makes the above “cid”, “uid (C)”, “did (C)”, “uid (D) to the conference terminal 100-3. ) "," Did (D) "," challenge_dC ", and" timestampC "," auth_result "and" password_tmp "are transmitted. Here, “auth_result” is use permission information for the guest user C by the conference system 20. “Password_tmp” is a password temporarily used when the guest user C uses the conference system 20.

  Finally, as shown in step S4015, the conference terminal 100-3 receives the use permission result from the conference server 300-2, and “uid (C)” associated with “cid” is temporarily registered regularly. The

  In the sequence described above, three types of time stamps “timestamp”, “timestamp_dC” (= “challenge_dC”), and “timestampC” are transmitted and received. These time stamps may be used as information for determining whether or not to authenticate the guest user C by comparing with the time when the conference is held. In addition, the time synchronization type authentication may be performed between the entities by using the time stamp issued by the conference terminal 100-3 and the time stamp issued by the conference terminal 100-4.

  In the second embodiment, unlike the first embodiment, there is no physical IWB, but the conference indicated by the address stored in the “WB” column in the conference information table of FIG. A virtual whiteboard can be used by using resources in the WB database 313 provided in the server 300-2.

  The code displayed on the screen of the conference terminal 100-4 is displayed by the conference server 300-2. That is, the code is generated by the conference server 300-2 and is sent from the conference server 300-2 to the conference terminal 100. 4 may be generated, input, or selected by the conference terminal 100-4 itself.

  In the above description, the user information manually input from the application screen 8002 displayed on the conference terminal 100-3 is described as the user information of the guest user C. However, the conference terminal 100-3 may be provided with a holding unit that is used in place of the input unit 102 or together with the input unit 102 and includes user information of the guest user A. Thereby, for example, it is possible to use user information held in advance by the conference terminal 100-3.

According to the present embodiment, when an online conference is held by a plurality of people, the security of the online conference system is ensured by using the multi-factor authentication process with the resources of registered users of the online conference system interposed. This makes it possible to easily use the online conference service.
