[Third embodiment]
Next, a third embodiment of the present invention will be described. In the present embodiment, the wireless communication devices of the first and second embodiments will be described more specifically.

  The wireless communication system of this embodiment includes a wireless communication device 30 and a wireless communication terminal 20. The wireless communication device 30 of the present embodiment is assumed to be an image forming device such as a multifunction device, a scanner, or a printer.

  FIG. 5 shows a configuration example of the wireless communication apparatus 30 of the present embodiment. In FIG. 5, a scanner unit 34, an operation display unit 35, an image information compression / playback unit 36, and a control unit 37 are added to the configuration example of FIG.

  The scanner unit 34 is a part that reads a document placed on a document table, and after reading the document, performs image processing and converts the document into electronic data.

  The operation display unit 35 is a part that accepts a user instruction and displays a message to the user.

  The image information compression / playback unit 36 is a part that receives the electronic data converted by the scanner unit 34 via the control unit 37 and compresses or expands the electronic data.

  The control unit 37 is a part that controls the scanner unit 34, the operation display unit 35, and the image information compression / playback unit 36.

  In the present embodiment, it is assumed that the communication method of the first wireless communication unit 11 is NFC (Near Field Communication), and the communication method of the second wireless communication unit 13 is a wireless LAN (Local Area Network). That is, in this embodiment, setting information for performing wireless LAN connection is transmitted from the wireless communication device 30 to the wireless communication terminal 20 by NFC, and the wireless communication terminal 20 communicates with the wireless communication device 30 using the received setting information. Make a wireless LAN connection.

  The first wireless communication unit 11 of the wireless communication device 30 corresponds to the NFC reader function in order to read the NFC tag of the wireless communication terminal 20. Further, in order to transmit the setting information to the wireless communication terminal 20, it is assumed that it corresponds to SNEP (Simple NDEF Exchange Protocol) in the peer-to-peer mode.

  NFC is a communication method capable of transmitting / receiving information to / from a device at a short distance without setting device information of a transmission / reception partner. Therefore, it is possible to transmit and receive information between the wireless communication device 30 and the wireless communication terminal 20 simply by holding the NFC-compatible wireless communication terminal 20 over the wireless communication device 30. Moreover, since the communication distance of NFC is about 10 cm, it is difficult to intercept communication. As a result, the possibility of unauthorized access can be further reduced.

  In the present embodiment, NFC is used as the communication method of the first wireless communication unit 11, but other communication methods that allow safe communication can also be used.

  The second wireless communication unit 13 corresponds to the wireless LAN access point function. Further, it is assumed that a DHCP (Dynamic Host Configuration Protocol) server function for giving out an IP (Internet Protocol) address to the wireless communication terminal 20 to be connected is also provided. By paying out the IP address to the wireless communication terminal 20, the wireless communication terminal 20 can communicate with the wireless communication apparatus 30 by an application or the like for controlling the wireless communication apparatus 30. Therefore, the wireless communication terminal 20 can acquire data scanned by the wireless communication device 30, transmit image data of the wireless communication terminal 20 to the wireless communication device 30, and print it.

  The setting information transmission unit 12 detects the wireless communication terminal 20 by receiving NDEF (NFC Data Exchange Format) data (arbitrary data) from the wireless communication terminal 20. Then, setting information for connecting the wireless communication terminal 20 to the second wireless communication unit 13 is transmitted to the wireless communication terminal 20 using SNEP. Also, when the second wireless communication is disconnected, setting information is newly generated.

  In the present embodiment, the setting information transmitted by the setting information transmitting unit 12 is assumed to be the private IP address, SSID (Service Set Identifier), and encryption key of the wireless communication device 30.

  As a method for generating the setting information, for example, a random number generated by a pseudo-random number generation algorithm such as Mersenne Twister is assigned to the SSID and the encryption key. For the private IP address, for example, an 8-digit random number is generated and assigned to the abcdefgh part from 192.168.ab.cd to 192.168.ef.gh.

  A configuration example of the wireless communication terminal 20 of the present embodiment is the same as that of FIG. The wireless communication terminal 20 is, for example, a smartphone or a tablet terminal. In the present embodiment, it is assumed that the user of the wireless communication device 30 possesses it.

In the present embodiment, similarly to the wireless communication device 30, the communication method of the first wireless communication unit 21 of the wireless communication terminal 20 is NFC, and the communication method of the second wireless communication unit 23 is a wireless LAN. The first wireless communication unit 21 is assumed to support SNEP in the peer-to-peer mode. (For example, in Android (registered trademark) OS (Operating System), the Android Beam function uses SNEP.)
By configuring the wireless communication device 30 in this way, the wireless communication device 30 transmits the setting information of the second wireless communication to the wireless communication terminal by the first wireless communication before establishing the second wireless communication. To do. Then, the second wireless communication is established with the wireless communication terminal based on the setting information. Also, when the second wireless communication is disconnected, setting information is newly generated. Therefore, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access.

  Also, by using NFC as the communication method of the first wireless communication, setting the second wireless communication between the wireless communication device and the wireless communication terminal is possible simply by holding the wireless communication terminal over the NFC reader of the wireless communication device. It becomes possible to send and receive information. In addition, the possibility of unauthorized access can be further reduced.

  Next, FIG. 6 shows an operation example of the wireless communication apparatus 30 of the present embodiment.

  First, the first wireless communication unit 11 of the wireless communication device 30 checks whether there is the wireless communication terminal 20 (step S301). Specifically, for example, reception confirmation of NDEF data is performed periodically (such as in a cycle of 500 ms).

  When the user activates the Android Beam function or the like of the wireless communication terminal 20, the wireless communication terminal 20 starts transmitting NDEF data. When the user holds the wireless communication terminal 20 over the NFC reader (corresponding to the first wireless communication unit 11) of the wireless communication device 30, the wireless communication device 30 detects the wireless communication terminal 20 by receiving the NDEF data. To do.

  When the setting information transmission unit 12 of the wireless communication device 30 detects the wireless communication terminal 20, the setting information transmission unit 12 newly generates setting information (step S302). For example, a private IP address, an SSID, and an encryption key (for example, “192.168.random number.random number” as a private IP address, “random number” as an SSID, and “random number” as an encryption key) are generated. Then, the setting information transmission unit 12 transmits the setting information to the wireless communication terminal 20 via the first wireless communication unit 11 (Step S303). In addition, setting information is set in the second wireless communication unit 13 of itself.

  When receiving the setting information from the wireless communication device 30, the wireless communication terminal 20 sets the received setting information in the second wireless communication unit 23. Then, the wireless communication terminal 20 requests the wireless communication device 30 to establish second wireless communication. The wireless communication device 30 receives a request from the wireless communication terminal 20 (step S304), and establishes second wireless communication (step S305).

  Here, when the second wireless communication is established, a message indicating that the remote operation is being performed is displayed on the operation display unit 35 of the wireless communication device 30 so that other users cannot operate the wireless communication device 30 as shown in FIG. You may do it.

  Furthermore, while the second wireless communication is established, another second wireless communication between the wireless communication device 30 and another wireless communication terminal may not be established. In this way, even if the setting information is intercepted, the other second wireless communication with another wireless communication terminal is not established, so that the possibility of unauthorized access can be further reduced.

  When the second wireless communication is disconnected (step S306), setting information is newly generated (step S307). In the present embodiment, setting information is newly generated in step S302 and step S307, but step S302 may be omitted.

  By operating the wireless communication device 30 in this manner, the wireless communication device 30 transmits the setting information of the second wireless communication to the wireless communication terminal by the first wireless communication before establishing the second wireless communication. To do. Then, the second wireless communication is established with the wireless communication terminal based on the setting information. Also, when the second wireless communication is disconnected, setting information is newly generated. Therefore, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access.

Send to the terminal. Then, the second wireless communication is established with the wireless communication terminal based on the setting information. Also, when the second wireless communication is disconnected, setting information is newly generated. Therefore, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access.

  Also, by using NFC as the communication method of the first wireless communication, setting the second wireless communication between the wireless communication device and the wireless communication terminal is possible simply by holding the wireless communication terminal over the NFC reader of the wireless communication device. It becomes possible to send and receive information. In addition, the possibility of unauthorized access can be further reduced.

[Fourth embodiment]

  In the present embodiment, the setting information transmission unit 12 monitors the communication status of the second wireless communication unit 13, and when the connection with the wireless communication terminal 20 is disconnected or the connection time with the wireless communication terminal 20 is a predetermined time. When reaching the above, setting information for the second wireless communication is newly generated.

  By configuring the wireless communication device 30 in this way, the wireless communication device 30 transmits the setting information of the second wireless communication to the wireless communication terminal by the first wireless communication before establishing the second wireless communication. To do. Then, second wireless communication is performed with the wireless communication terminal based on the setting information. Also, when the second wireless communication is disconnected, setting information is newly generated. Therefore, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access.

  In addition, when the connection time of the second wireless communication with the wireless communication terminal 20 reaches a predetermined time, the wireless communication device 30 of the present embodiment disconnects the second wireless communication and newly generates setting information. . In order for the wireless communication terminal 20 to continue using the wireless communication device 30, it is necessary to receive the setting information again. Therefore, the user is given a chance to end the use of the wireless communication device 30, and it is possible to reduce the specific user from occupying the wireless communication device 30 for a long time.

  Next, FIG. 8 shows an example of the operation of the wireless communication apparatus 30 of the present embodiment. The operation example of FIG. 8 is performed instead of step S306 of FIG. Since the operation example of FIG. 6 is the same as that of the third embodiment, the description thereof is omitted here.

  In step S305, the second wireless communication (wireless LAN) between the wireless communication device 30 and the wireless communication terminal 20 is established. When the second wireless communication is established, the setting information transmission unit 12 starts a timer (step S401).

  Then, the setting information transmission unit 12 monitors the communication state of the second wireless communication, and when the second wireless communication is disconnected (step S402), newly generates setting information of the second wireless communication (step S402). S307). Also when the timer reaches a predetermined time and the time is up (step S403), the second wireless communication is disconnected (step S404), and the second wireless communication setting information is newly generated (step S307). ). If the operation display unit 35 displays that the remote operation is being performed, the display is canceled. And it returns to the detection operation | movement of the radio | wireless communication terminal 20 of step S301.

  For example, the setting information transmission unit 12 confirms the communication status of the second wireless communication every second and adds a timer. It is assumed that the timer is initialized to 0 in step S401. When the timer reaches a predetermined time (for example, 300 seconds) and the time is up, it is determined that the operation from the established wireless communication terminal 20 is finished, and setting information is newly generated. The setting of the second wireless communication unit 13 is updated.

  By operating the wireless communication device 30 in this way, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access. Become.

  In addition, when the connection time of the second wireless communication with the wireless communication terminal 20 reaches a predetermined time, the wireless communication device 30 of the present embodiment disconnects the second wireless communication and newly generates setting information. . Therefore, it is possible to reduce a specific user from occupying the wireless communication device 30 for a long time.

[Fifth embodiment]
Next, a fifth embodiment of the present invention will be described. This embodiment is a form in which a function for confirming whether or not a wireless communication terminal is permitted to connect to the wireless communication apparatus is added to the wireless communication apparatuses of the first to fourth embodiments.

  The wireless communication system of this embodiment includes a wireless communication device 40 and a wireless communication terminal 50.

  FIG. 9 shows a configuration example of the wireless communication terminal 50 of the present embodiment. An authentication information transmission unit 54 is added to the configuration example of FIG.

  The authentication information transmission unit 54 is a part that transmits the access key to the wireless communication device 40 via the first wireless communication unit 21. The access key is information indicating that the wireless communication terminal 50 is permitted to connect to the wireless communication device 40, and is set in the wireless communication terminal 50 by the user in advance. The authentication information transmission unit 54 transmits the access key on the NDEF data.

  FIG. 10 shows a configuration example of the wireless communication device 40 of the present embodiment. An authentication unit 48 is added to the configuration example of FIG. Moreover, you may add the authentication part 48 with respect to the structural example of FIG.

  The authentication unit 48 is a part that authenticates whether the wireless communication terminal 50 is a wireless communication terminal 50 that is permitted to connect to the wireless communication device 40. The authentication unit 48 performs authentication by confirming whether there is an access key received from the wireless communication terminal 20 in the access key list registered in advance.

  When the second wireless communication unit 13 authenticates that the wireless communication terminal 50 is a wireless communication terminal 50 permitted to connect, the second wireless communication unit 13 transmits setting information to the wireless communication terminal 50.

  FIG. 11 shows an example of an access key list. In the example of FIG. 11, an access key is issued for each user. The user registers this access key in the wireless communication terminal 50.

  By configuring the wireless communication device 40 in this way, the wireless communication device 40 transmits the setting information of the second wireless communication to the wireless communication terminal by the first wireless communication before establishing the second wireless communication. To do. Then, the second wireless communication is established with the wireless communication terminal based on the setting information. Also, when the second wireless communication is disconnected, setting information is newly generated. Therefore, it is possible to perform communication settings between the wireless communication device and the wireless communication terminal without using an intermediary server, and to reduce the possibility of unauthorized access.

  In this embodiment, since the wireless communication apparatus authenticates the wireless communication terminal, it is possible to prevent connection of a wireless communication terminal that is not permitted to connect to the wireless communication apparatus.

  Next, FIG. 12 shows an example of the operation of the wireless communication device 40 of the present embodiment. The operation example of FIG. 12 is performed between step S301 and step S302 of FIG. Since the operation example of FIG. 6 is the same as that of the third embodiment, the description thereof is omitted here.

  First, the user (referred to as Mr. A) registers an access key (for example, “12345678”) in advance in the wireless communication terminal 50 before connecting the wireless communication terminal 50 to the wireless communication device 40. The administrator of the wireless communication device 40 registers an access key list as shown in FIG. 11 in the wireless communication device 40, for example.
