  Next, the authentication unit 52 of the terminal management server 5 performs login authentication of the IC card 3 using the terminal ID (step S14). Specifically, the storage / reading processing unit 59 searches for a user ID corresponding to the terminal ID in the terminal management table (see FIG. 12A) using the terminal ID received in step S13 as a search key. . If there is a corresponding user ID, the authentication unit 52 determines that the IC card (terminal ID) is valid. If there is no corresponding user ID, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2x (step S15). When the authentication unit 52 determines that the IC card is a valid IC card, the authentication result includes information indicating that the card is valid, a user ID, and a user name. If the authentication unit 52 determines that the IC card is not valid, the authentication result includes information indicating that it is not valid. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the authentication result.

  Next, the electronic blackboard 2x performs processing based on the authentication result (step S16). Here, the process based on the authentication result in step S16 will be described in detail with reference to FIG. FIG. 16 is a flowchart illustrating processing based on the authentication result when logging in.

  As shown in FIG. 16, the determination unit 25 is information indicating that the authentication result received in step S15 is valid (that is, whether the terminal ID transmitted in step S13 is valid). ) Is determined (step S16-1). When the determination unit 25 determines that the information is not valid, that is, when it is determined that the login has failed (NO), the display control unit 24 displays the information on the display 220 in FIG. As shown in FIG. 5, an error screen 180 is displayed (step S16-2). When the determination unit 25 determines that the information is valid, that is, when it is determined that the login is successful (YES), the setting unit 27 displays the logged-in user (here, the user). A) is set as the printer (step S16-3). Then, the process proceeds to step S17. Hereinafter, the explanation will be continued with respect to the case where it is valid.

  The transmission / reception unit 21 of the electronic blackboard 2x transmits an e-mail address request to the destination management server 6 (step S17). This request includes the user ID received in step S15. Thereby, the transmission / reception unit 61 of the destination management server 6 receives the request for the e-mail address.

  Next, in the destination management server 6, the storage / reading processing unit 69 searches the destination management table (see FIG. 12B) using the user ID received in step S37 as a search key. The e-mail address is read (step S18). And the transmission / reception part 61 transmits a request result with respect to the electronic blackboard 2x (step S19). This request result includes the e-mail address read in step S18. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the request result.

  Next, the setting unit 27 of the electronic blackboard 2x sets the transmission source and transmission destination of the electronic mail (step S20). As a result, when the display control unit 24 displays the e-mail setting screen 280 shown in FIG. 10B, the user who has logged in from the e-mail address of the electronic blackboard 2 is displayed in the e-mail address field 283 of the transmission source. Switch to the e-mail address. When the display control unit 24 displays the e-mail setting screen 280 shown in FIG. 10A, the address setting field 274 displays the e-mail address of the logged-in user.

  Next, the display control unit 24 uses a ticker indicating that drawing of “Welcome, Mr. Kato” or the like can be started on the display 220 as shown in FIG. Display. As the characters “Kato”, the user name received in step S15 is used. Thus, users A and B can draw on the electronic blackboard 2x.

<Send email>
Next, with reference to FIGS. 17 to 18, a description will be given of a process in which the users A and B transmit e-mails attached with drawing image data from the electronic blackboard 2x to their PCs 10a and 10b, respectively. FIG. 17 is a sequence diagram showing processing when drawing image data is transmitted by electronic mail. FIG. 18 is a flowchart showing processing based on the authentication result when drawing image data is transmitted by e-mail.

  After the users A and B proceed with the conference while drawing on the electronic blackboard 2x using the electronic pen 2500, the user A uses the electronic pen 2500 and the “menu” button shown in FIG. 8B. By pressing 231 and then pressing the “send mail” button 237, the display control unit 24 displays the destination setting screen 270 shown in FIG. 10A on the display 220 (step S31). In this way, when the destination setting screen 270 is displayed, as shown in FIG. 10A, the e-mail address of the logged-in user A is displayed in the address setting field 274 from the beginning. Note that the “direct input” tab 272 may be selected, and the user's own e-mail address may be input using the electronic pen 2500 or the like.

  Next, when the user B who is not logged in also wants to include his / her e-mail address as a destination, the electronic blackboard 2x is obtained by bringing his / her smartphone 4 close to the short-range communication unit 221 of the electronic blackboard 2 The providing unit 28 acquires a terminal ID for identifying the smartphone 4 (an example of a dedicated terminal) from the acquiring / providing unit 48 of the smartphone 4 (step S32).

  Next, the transmitting / receiving unit 21 of the electronic blackboard 2x transmits an authentication request for the smartphone 4 to the terminal management server 5 (step S33). This authentication request includes the terminal ID of the smartphone 4 acquired by the acquisition / providing unit 28. Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

  Next, the authentication unit 52 of the terminal management server 5 authenticates the smartphone 4 using the terminal ID (step S34). Specifically, the storage / reading processing unit 59 searches for a user ID corresponding to the terminal ID in the terminal management table (see FIG. 12A) using the terminal ID received in step S33 as a search key. . If there is a corresponding user ID, the authentication unit 52 determines that the smartphone is a valid smartphone 4 (terminal ID). If there is no corresponding user ID, the authentication unit 52 determines that it is not a valid smartphone 4 (terminal ID).

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2x (step S35). When the authentication unit 52 determines that the smartphone is a valid smartphone (terminal ID), the authentication result includes information indicating that the authentication is valid, a user ID, and a user name. When the authentication unit 52 determines that the smartphone is not a valid smartphone (terminal ID), the authentication result includes information indicating that the authentication is not valid. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the authentication result.

  Next, the electronic blackboard 2x performs processing based on the authentication result (step S36). Here, the process based on the authentication result in step S36 will be described in detail with reference to FIG. FIG. 18 is a flowchart showing processing based on the authentication result when drawing image data is transmitted by e-mail.

  As shown in FIG. 18, the determination unit 25 is information indicating that the examination result received in step S35 is valid (that is, whether the terminal ID transmitted in step S33 is valid). ) Is determined (step S36-1). If the determination unit 25 determines that the information is not valid (NO), the display control unit 24 displays an error screen on the display 220 as shown in FIG. 14B. 180 is displayed (step S36-2). If the determination unit 25 determines that the information is valid (YES), the user ID received in step S35 is the user ID of the logged-in user A. It is determined whether they are the same (step S36-3). And when the judgment part 25 judges that it is the same (YES), it progresses to below-mentioned step S41. On the other hand, when the determination unit 25 determines that they are not the same (NO), the transmission / reception unit 21 of the electronic blackboard 2x transmits an e-mail address request to the destination management server 6 (step S37). This request includes the user ID received in step S35. Here, it is the user ID of user B. Thereby, the transmission / reception unit 61 of the destination management server 6 receives the request for the e-mail address.

  Next, in the destination management server 6, the storage / reading processing unit 69 searches the destination management table (see FIG. 12B) using the user ID received in step S37 as a search key. The e-mail address is read (step S38). And the transmission / reception part 61 transmits a request result with respect to the electronic blackboard 2x (step S39). This request result includes the e-mail address read out in step S38. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the request result.

  Next, the display control unit 24 of the electronic blackboard 2x, as shown in FIG. 14D, displays the email address (USER1 @...) Of the user A already displayed in the address setting field 274. ) And the user B's e-mail address (USER2 @...) Is additionally displayed (step S40).

  Subsequently, when the reception unit 22 of the electronic blackboard 2x receives a press of the “Send” button 277 by the user A or the user B, the creation unit 26a of the electronic blackboard 2x reads the drawing image data in the bitmap format from Image data in PDF format is created (step S41). Then, the transmitting / receiving unit 21 transmits an e-mail attached with the image data created in step S41 to the mail server 7 (step S42). Accordingly, the transmission / reception unit 71 of the mail server 7 receives an e-mail to which image data in PDF format is attached. At this time, the e-mail includes the e-mail address of the logged-in user A as the transmission source and the e-mail address of the logged-in user A as the transmission destination (destination). In addition, when the user B is approaching the smartphone 4 to the short-range communication unit 221, the email address of the user B who is not logged in is also included as the transmission destination (destination). That is, in this case, since the transmission source is changed not to the electronic blackboard 2x but to the email address of the user A in step S20, the user A transmits the email address to himself / herself. . In addition, as user B, the user A receives an e-mail address. Hereinafter, the case where the electronic mail address of the user B is also included will be described.

  The transmission / reception unit 71 of the mail server 7 transmits an e-mail attached with image data in PDF format to the PCs 10a and 10b. (Steps S43, S44). At this time, the e-mail includes the e-mail address of the sender who is the user A and the e-mail addresses of the PCs 10a and 10b which are the e-mail addresses received at step S39. . As a result, the PCs 10a and 10b each receive an e-mail attached with image data in PDF format.

<Printing of drawing image data>
Next, with reference to FIGS. 19 to 23, a case will be described in which after the drawing by the users A and B, the drawing image data is transmitted from the electronic blackboard 2x to the MFP 9 via the print server 8 and finally printed. FIG. 19 is a sequence diagram illustrating a print preparation process for drawing image data. FIG. 20 is a flowchart illustrating processing based on the authentication result in the case of printing. FIG. 21 is a diagram illustrating a display example of the print setting screen.

  After the users A and B proceed with the conference while drawing on the electronic blackboard 2x using the electronic pen 2500, the user A uses the electronic pen 2500 and the “menu” button shown in FIG. 8B. By pressing 231 and then pressing the “print” button 236, the display control unit 24 displays the print setting screen 260 shown in FIG. 9D on the display 220 (step S51). The setting unit 27 sets the user name of the logged-in user A as the printer name, and the display control unit 24 sets the user name of the logged-in user A as the printer name on the print setting screen 260. it's shown.

  Next, as shown in FIG. 15, when the user A brings his IC card 3 close to the short-range communication unit 221 of the electronic blackboard 2x, the acquisition / providing unit 28 of the electronic blackboard 2 causes the IC card. Terminal ID for identifying the IC card 3 (an example of a dedicated terminal) is acquired from the acquiring / providing unit 38 (step S52). Then, the transmission / reception unit 21 of the electronic blackboard 2x transmits an authentication request for the IC card 3 to the terminal management server 5 (step S53). This authentication request includes the terminal ID of the IC card 3 acquired by the acquisition / providing unit 28. Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

  Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the terminal ID (step S54). Specifically, the storage / reading processing unit 59 searches for the user name corresponding to the terminal ID in the terminal management table (FIG. 12A) using the terminal ID received in step S53 as a search key. If there is a corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is valid. If there is no corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2x (step S55). When the authentication unit 52 determines that the IC card is a valid IC card, the authentication result includes information indicating that it is valid and a user name. If the authentication unit 52 determines that the IC card is not valid, the authentication result includes information indicating that it is not valid. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the authentication result.

  Next, the electronic blackboard 2x performs processing based on the authentication result (step S56). Here, the process based on the authentication result in step S56 will be described in detail with reference to FIG. FIG. 20 is a flowchart illustrating processing based on the authentication result in the case of printing.

  As illustrated in FIG. 20, the determination unit 25 is information indicating that the examination result received in step S55 is valid (that is, whether the terminal ID transmitted in step S53 is valid). ) Is determined (step S56-1). If the determination unit 25 determines that the information is not valid (NO), the display control unit 24 displays an error screen on the display 220 as shown in FIG. 14B. 180 is displayed (step S56-2). If the determination unit 25 determines that the information is valid (YES), the user ID received in step S55 is the user ID of the logged-in user A. It is determined whether they are the same (step S56-3). And when the judgment part 25 judges that it is the same (YES), it progresses to below-mentioned step S57. On the other hand, if the determination unit 25 determines that they are not the same (NO), the setting unit 27 changes the printer name to the user name received in step S55 (step S56-4). For example, when the display control unit 24 displays the print setting screen 260 shown in FIG. 9D and the logged-in user A brings his IC card 3 close to the short-range communication unit 221. The printer name remains “Kato” and is not changed. On the other hand, when the display control unit 24 displays the print setting screen 260 shown in FIG. 9D, the user B who is not logged in has his / her smartphone 4 in the short-range communication unit 221. , The printer name is changed from “Kato” to “Jim” as shown in FIG. After step 56-4, the process proceeds to step S57.

  Next, returning to FIG. 19, the reception unit 22 of the electronic blackboard 2 x uses the electronic pen 2500 from the user A in FIG. 9D or from the user B in FIG. And a press of the “print” button 267 is accepted (step S57). Thereby, the creation unit 26b creates print data as image data in the PDL format from the bitmap format drawing image data obtained by the drawing by the users A and B (step S58).

  Next, the transmission / reception unit 21 of the electronic blackboard 2x transmits the print data created in step S58 to the print server 8 (step S59). This print data includes information related to the print data (printer name, file name, and print setting parameter). Thereby, the transmission / reception unit 81 of the print server 8 receives the print data.

  Next, the storage / reading processing unit 89 of the print server 8 stores the print data received in step S59 in the storage unit 8000 (step S60). Further, the storage / reading processing unit 89 performs information (printer name, file name, and print setting parameter) related to the print data received in step S59 with respect to the print data management table (see FIG. 12C). ) Are stored in association with each other (step S61). Thus, the print preparation process ends.

  Next, a case of finally printing will be described with reference to FIGS. FIG. 22 is an image diagram showing a state in which the user uses the MFP. FIG. 23 is a sequence diagram illustrating a printing process of drawing image data. Here, a case where the user A prepares for printing in the print preparation process (steps S51 to S61) will be described. In FIG. 22, the short-range communication unit 921 in the MFP 9 is a part that executes processing by the acquisition / providing unit 98.

  First, when the user A moves to the installation location of the MFP 9 and brings his IC card 3 close to the short-range communication unit 921 of the MFP 9 as shown in FIG. 22, as shown in FIG. Then, the acquisition / provision unit 98 of the MFP 9 acquires a terminal ID for identifying the IC card (an example of a dedicated terminal) from the acquisition / provision unit 38 of the IC card 3 (step S71). Then, the transmission / reception unit 91 of the MFP 9 transmits an authentication request for the IC card 3 to the terminal management server 5 (step S72). This authentication request includes the terminal ID of the IC card 3 acquired by the acquisition / providing unit 98. Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

  Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the terminal ID (step S73). Specifically, the storage / reading processing unit 59 searches for a user name corresponding to the terminal ID in the terminal management table (FIG. 12A) using the terminal ID received in step S72 as a search key. If there is a corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is valid. If there is no corresponding user name, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits an authentication result to the MFP 9 (step S74). When the authentication unit 52 determines that the IC card is a valid IC card, the authentication result includes information indicating that the card is valid, a user ID, and a user name. If the authentication unit 52 determines that the IC card is not valid, the authentication result includes information indicating that it is not valid. Thereby, the transmission / reception unit 91 of the MFP 9 receives the authentication result.

  Next, the MFP 9 performs processing based on the authentication result (step S75). Specifically, when the determination unit 95 determines the content of the authentication result and determines that the authentication result includes information indicating that the authentication result is not valid, printing is not performed, but the authentication result is determined to be valid. If it is determined that the information shown is included, the process proceeds to step S76. Hereinafter, description will be continued for a case where the authentication result includes information indicating that the authentication result is valid.

  The transmission / reception unit 91 of the MFP 9 transmits a request for print data to the print server 8 (step S76). This request includes the user name received in step S74. Thereby, the transmission / reception unit 81 of the print server 8 receives the request for the print data.

  Next, in the print server 8, the storage / read processing unit 89 searches the print data management table (see FIG. 12B) using the user name received in step S74 as a search key. A file name is read (step S77). Further, the storage / reading processing unit 89 reads out the print data of the file name read out in step S77 from the storage unit 9000 (step S78). The transmission / reception unit 81 transmits print data to the MFP 9 (step S79). This print data includes the user name received in step S76. Thereby, the transmission / reception unit 91 of the MFP 9 receives the print data.

  Next, in the MFP 9, the printing unit 93 prints an image on a printing sheet based on the print data, and outputs it (step S80). In addition, although the user name was transmitted / received in step S76, S79, not only this but user ID may be sufficient. In this case, in step 77, the user ID is used as a search key. Thus, the printing process ends.

<End processing>
Next, with reference to FIG. 24 and FIG. 25, an end process will be described as an example of a process other than the above-described electronic mail transmission and printing. FIG. 24 is a sequence diagram illustrating a drawing end process. FIG. 25 is a flowchart showing an end process when a folder is selected at the time of saving. Here, a case where the user A brings his IC card 3 close to the short-range communication unit 221 of the electronic blackboard 2x will be mainly described.

  After the users A and B proceed with the conference while drawing on the electronic blackboard 2x using the electronic pen 2500, the user A uses the electronic pen 2500 and the “menu” button shown in FIG. 8B. By pressing 231 and then pressing the “save” button 235, the display control unit 24 displays the folder selection screen 250 shown in FIG. 9C on the display 220 (step S91).

  Next, when the user A brings his IC card 3 close to the short-range communication unit 221 of the electronic blackboard 2x, the acquisition / providing unit 28 of the electronic blackboard 2x A terminal ID for identifying the IC card 3 (an example of a dedicated terminal) is acquired (step S92).

  Next, the transmitting / receiving unit 21 of the electronic blackboard 2x transmits an authentication request for the IC card 3 to the terminal management server 5 (step S93). This authentication request includes the terminal ID of the IC card 3 acquired by the acquisition / providing unit 28. Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

  Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the terminal ID (step S94). Specifically, the storage / read processing unit 59 searches for a user ID corresponding to the terminal ID in the terminal management table (see FIG. 12A) using the terminal ID received in step S93 as a search key. . If there is a corresponding user ID, the authentication unit 52 determines that the IC card (terminal ID) is valid. If there is no corresponding user ID, the authentication unit 52 determines that the IC card (terminal ID) is not valid.

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits the authentication result to the electronic blackboard 2x (step S95). When the authentication unit 52 determines that the IC card (terminal ID) is valid, the authentication result includes information indicating that it is valid, a user ID, and a user name. In addition, when the authentication unit 52 determines that the IC card (terminal ID) is not valid, the authentication result includes information indicating that it is not valid. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the authentication result.

  Next, the electronic blackboard 2x performs processing based on the authentication result (step S96). Here, the process based on the authentication result in step S96 will be described in detail with reference to FIG.

  As shown in FIG. 25, the determination unit 25 is information indicating that the examination result received in step S95 is valid (that is, whether the terminal ID transmitted in step S93 is valid). ) Is determined (step S96-1). If the determination unit 25 determines that the information is not valid (NO), the display control unit 24 displays an error screen on the display 220 as shown in FIG. 14B. 180 is displayed (step S96-2). If the determination unit 25 determines that the information is valid (YES), the user ID received in step S95 is the user ID of the logged-in user A. It is determined whether they are the same (step S96-3). If the determination unit 25 determines that they are the same (YES), the display control unit 24 displays an end screen 238 as shown in FIG. 8C on the display 220 ( Step S96-4). On the other hand, if the determination unit 25 determines that they are not the same (NO), the process proceeds to step S96-2, and the display control unit 24 is displayed on the display 220 as shown in FIG. Error screen 180 is displayed.

  As described above, as an example of the screen other than the e-mail destination setting screen 270 shown in FIG. 10A and the print setting screen 260 shown in FIG. When the logged-in user A approaches his / her IC card 3 to the short-range communication unit 221 while the folder selection screen 250 shown in FIG. Display control unit 24 displays an end screen 238 shown in FIG. 8C. On the other hand, the display control unit 24 logs in when a screen other than the e-mail destination setting screen 270 shown in FIG. 10A and the print setting screen 260 shown in FIG. 9 is displayed. When the user B who has not been brought close to his / her smart phone 4 to the short-range communication unit 221, the determination unit 25 determines that the user B has made an erroneous operation, and the display control unit 24 is shown in FIG. The error screen 180 displayed is displayed.

  As other examples other than the e-mail destination setting screen 270 and the print setting screen 260 shown in FIG. 9, for example, a drawing screen 230 (FIG. 8A), a menu selection screen 232 (FIG. 8). (B)), folder selection screen 240 at the time of reading (FIG. 9A), file selection screen 245 at the time of reading (FIG. 9B), e-mail setting screen 280 (FIG. 10B), QR code Each screen of a display screen (FIG.10 (C)) is mentioned.

<< Main effects of embodiment >>
As described above, according to the present embodiment, even a shared terminal such as an electronic blackboard 2x that can be shared by a plurality of users is used exclusively for a terminal such as an IC card used for login. Thus, there is an effect that security can be ensured.

  When the logged-in user A brings his / her IC card 3 close to the electronic blackboard 2x, the process proceeds to the display of the end screen 238 (see FIG. 8C) (see S96-4). When the user's own smart phone 4 comes close to the electronic blackboard 2x, the process proceeds to display an error screen 180 (see FIG. 14B) (see S96-2). Thereby, the user A who has logged in easily in the vicinity of the IC card 3 can easily log out in the vicinity of the IC card 3. Further, the electronic blackboard 2x can ensure security by not accepting logout even when the user B who is not logged in brings the smartphone 4 close to the electronic blackboard 2x.

  Moreover, since the setting unit 27 sets the email address of the logged-in user A as the transmission source mail address and the transmission destination mail address (see S20), the user A can easily set the transmission source and the transmission destination. Can be done. Further, when the destination setting screen 270 (see FIG. 10A) is displayed, if the user B who is not logged in brings his / her smartphone 4 close to the electronic blackboard 2x, the display control unit 24 displays the destination setting screen. The electronic mail address of user B is additionally displayed on 270 (see FIG. 14D) (see S40). As a result, when user B wants to send drawing image data to his / her PC 10b, it is not necessary to bother to input or select his / her own e-mail address, thereby saving the trouble of setting the e-mail address.

  The setting unit 27 sets the user name of the logged-in user A as the printer name, and the display control unit 24 sets the user name of the logged-in user A as the printer name on the print setting screen 260. Is displayed (see S51). Thereby, the user A can easily set the printer name. Furthermore, when the print setting screen 260 (see FIG. 9D) is displayed, if the user B who is not logged in brings his / her smartphone 4 close to the electronic blackboard 2x, the display control unit 24 displays the print setting screen. In 260 (see FIG. 21), the printer name is changed from the user name of the logged-in user A to the user name of the user B (S56-4). Thereby, even if the user B who has not logged in wants to print the drawing image data, it can be printed easily. That is, when adopting a secure print in which printing is not started unless the user moves to the installation location of the MFP 9 and brings his own dedicated terminal close to the user, the user B who has not logged in tries to print to his MFP 9 Cannot print even if 4 (exclusive terminal) is in close proximity. However, in this embodiment, if the user B brings his / her smartphone 4 (proprietary terminal) close to the electronic blackboard 2x, the printer becomes the user B. In addition, printing by secure printing is possible.

<< Other processing or operation >>
Next, other processes or operations will be described with reference to FIG. FIG. 28 is a sequence diagram illustrating another communication process of data relating to an image in the second embodiment. In addition, since this embodiment performs the process of step S113-S117 instead of the process of step S13, S14 of 1st Embodiment shown by FIG. 13, about the process of step S113-S117 hereafter. explain. A plurality of terminal management servers 5 may be installed.

  First, in step S12 shown in FIG. 11, when the obtaining / providing unit 28 of the electronic blackboard 2x obtains the terminal ID of the IC card from the obtaining / providing unit 38 of the IC card 3, in FIG. The 2x transmission / reception unit 21 transmits the connection key k1 to the terminal management server 5 (step S113). Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the connection key k1. The connection key k1 is issued as a client of the terminal management server 5 that holds information to be authenticated, and is stored in advance in the storage unit 2000 of the electronic blackboard 2x.

  On the other hand, the issued connection key k2 is also stored in the storage unit 5000 on the terminal management server 5 side. Then, the determination unit 55 of the terminal management server 5 determines whether or not access is possible by determining whether or not the received connection key k1 is the same as the stored connection key k2 (step S114). If the connection key k1 and the connection key k2 are the same, the determination unit 55 determines that access is possible. If the connection key k1 and the connection key k2 are not the same, the determination unit 55 determines that access is impossible.

  Next, the transmission / reception unit 51 of the terminal management server 5 transmits the determination result to the electronic blackboard 2x (step S115). When the determination unit 55 determines that access is possible, the determination result includes information indicating that access is possible and access information a1. If the determination unit 55 determines that access is not possible, the determination result includes information indicating that access is not possible. Thereby, the transmission / reception unit 21 of the electronic blackboard 2x receives the determination result. The access information a1 is, for example, a unique random alphanumeric string of 16 characters, 32 characters, 64 characters, and the like. If the access information a1 is determined to be accessible by the determination unit 55, the determination unit 55 continues. Information generated by The generated access information a1 is temporarily stored in the storage unit 5000 by the storage / read processing unit 59.

  Next, the electronic blackboard 2x performs processing based on the determination result (step S116). As an example of this processing, when the determination result includes information indicating that access is not possible, the display control unit 24 displays on the display 220 that access is not possible. If the determination result includes information indicating that access is possible, the process proceeds to step S117. Hereinafter, the description will be continued with respect to the case where access is possible.

  The transmission / reception unit 21 of the electronic blackboard 2x transmits an authentication request to the terminal management server 5 (step S117). This authentication request includes the terminal ID acquired in step S12 and the access information a2. Thereby, the transmission / reception unit 51 of the terminal management server 5 receives the authentication request.

  Next, the authentication unit 52 of the terminal management server 5 authenticates the IC card 3 using the access information a2 and the terminal ID (step S118). Specifically, the determination unit 55 determines whether the received access information a2 matches the access information a1 temporarily stored in the storage unit 5000, and determines that they match. In such a case, the authentication unit 52 further executes an authentication process as in step S14 described above. On the other hand, when the determination unit 55 determines that the received access information a2 and the access information a1 temporarily stored in the storage unit 5000 do not match, the authentication unit 52 performs the authentication process. Without executing, the transmission / reception unit 51 transmits information indicating that it is not valid to the electronic blackboard 2x. Since this process is the same as the process after step S14 in the first embodiment, a description thereof will be omitted.

  Note that after the process of step S114, the transmission / reception unit 51 may perform the transmission of step S115 after encrypting the access information.

<< Main effects of other processes or actions >>
As described above, according to the present embodiment, the terminal management server 5 determines whether the electronic blackboard 2x (shared terminal) is a licensed valid terminal as well as authentication using the terminal ID. Therefore, in addition to the first embodiment, it is possible to provide a communication system in which security is further ensured.

  If there are a plurality of terminal management servers 5, the electronic blackboard 2x responds that access is not possible when it sends an authentication request to the terminal management server that has not generated access information in step S114. There is an effect that the legitimacy can be strengthened.
