Moreover, you may combine arbitrarily at least one part of embodiment described below.

[Configuration of communication system]
FIG. 1 is a diagram showing a configuration of a communication system according to an embodiment of the present invention.

  Referring to FIG. 1, a communication system 201 includes an information change control system 151, an out-of-home terminal device 22, and in-home devices 33A, 33B, and 33C. The information change control system 151 includes a home terminal device 32 and a gateway device 101. The home terminal device 32 includes a display unit 32A and an operation unit 32B.

  Hereinafter, each of the home devices 33A, 33B, and 33C is also referred to as a home device 33. In FIG. 1, three in-home devices 33 are representatively shown, but a larger or smaller number of in-home devices 33 may be provided.

  The gateway device 101, the home terminal device 32, and the home device 33 are installed in homes such as homes and offices. The gateway device 101 is connected to a home terminal device 32 and a home device 33 via a home network 31 such as a LAN (Local Area Network) or the like by wired or wireless communication. The gateway device 101 may be directly connected to at least one of the home terminal device 32 and the home device 33 without going through the home network 31.

  The out-of-home terminal device 22 is, for example, a smartphone or a PC (Personal Computer), and is connected to the gateway device 101 via a wired or wireless connection via an external network 21 such as the Internet. The out-of-home terminal device 22 may be directly connected to the gateway device 101 without going through the external network 21. In FIG. 1, one out-of-home terminal device 22 is representatively shown, but a plurality of out-of-home terminal devices 22 may be provided.

  The gateway device 101 connects, for example, the external network 21 and the home network 31 having different protocols. Note that the same protocol may be used in the external network 21 and the home network 31.

  The gateway device 101 performs a relay process for relaying information exchanged between the external terminal device 22 connected to the external network 21 and the indoor device 33 connected to the home network 31.

  More specifically, the gateway device 101 holds communication setting information for communicating with other devices, specifically, the out-of-home terminal device 22 and the in-home device 33, and includes the communication setting information held therein. Based on this, the information received from the in-home device 33 is transmitted to the out-of-home terminal device 22, and the information received from the out-of-home terminal device 22 is transmitted to the in-home device 33.

  The in-home device 33A is a sensor, for example, and can detect the lock state of the door and window keys, measure the temperature of the range, and the like. The in-home device 33B is, for example, a driving device, and can lock the door and window keys, extinguish the range, and the like.

  The in-home device 33A transmits, for example, sensor information indicating the detection result of the lock state of the door and window keys and the measurement result of the temperature of the range to the outside terminal device 22 via the gateway device 101.

  For example, when receiving the sensor information from the in-home device 33A, the outside terminal device 22 displays the content of the received sensor information on the display.

  As a result, the user of the out-of-home terminal device 22 can recognize the lock state of the door and window keys and the temperature of the range, for example, even when away from home based on the display on the display. Specifically, for example, when the user of the out-of-home terminal device 22 forgets to close the door key and goes out, the user notices that the door key is unlocked based on the display on the display. be able to.

  When the user of the out-of-home terminal device 22 recognizes the unlocked state, for example, the user performs an operation on the out-of-home terminal device 22 to lock the door key in the in-home device 33B. The out-of-home terminal device 22 transmits command information indicating locking of the door key to the in-home device 33B via the gateway device 101 based on a user operation.

  Upon receiving the command information from the out-of-home terminal device 22, the in-home device 33B locks the door key according to the received command information.

  Note that the gateway device 101 is not limited to a configuration that relays information exchanged between the out-of-home terminal device 22 and the in-home device 33, but processes information received from the in-home device 33, and the processing result is transmitted to the in-home device 33 or It may be configured to transmit to the outside terminal device 22.

  FIG. 2 is a diagram showing an example of a screen displayed on the display unit of the home terminal device according to the embodiment of the present invention.

  The in-home terminal device 32 is, for example, a smartphone or a PC, and can execute the program of the web browser 34.

  The display unit 32A in the in-home terminal device 32 is a display, for example, and can display the web browser 34 as shown in FIG.

  The operation unit 32B is, for example, a keyboard and mouse, or a touch panel provided in combination with the display unit 32A, that is, the screen portion of the display, and receives an operation of a user of the home terminal device 32 (hereinafter also referred to as a home user).

  The home user operates, for example, the operation unit 32B to input an arbitrary URL (Uniform Resource Locator) into the address input area 34A of the web browser 34 displayed on the display unit 32A. For example, the home terminal device 32 transmits a request for web information to be displayed on the web browser 34 to a device that manages the web information indicated by the URL, based on the input of the home user.

  The gateway device 101 functions as a server, for example. For example, when the gateway device 101 is a device that manages the web information indicated by the URL, the gateway device 101 transmits the web information indicated by the URL to the home terminal device 32 in response to a request from the home terminal device 32. To do.

  The in-home terminal device 32 displays a web page based on the web information transmitted from the gateway device 101 in the page area 34B. Thereby, the home user can visually recognize the content of the web information indicated by the URL input by the user based on the web page displayed in the page area 34B.

[Task]
For example, the home user can perform initial registration and update of the communication setting information held by the gateway device 101 via the home terminal device 32. The gateway apparatus 101 performs an authentication process, for example, in order to confirm the legitimacy of a home user before permitting initial registration and update by the home terminal apparatus 32 of its communication setting information.

  For example, when a home user inputs his / her ID and a password corresponding to the ID to the home terminal device 32, and the home terminal device 32 transmits the ID and password input by the home user to the gateway device 101, the gateway device 101 The authentication process is successful. Then, upon successful authentication processing, the gateway device 101 permits initial registration and update by the home terminal device 32 of its communication setting information.

  However, for example, when the home user does not remember the correct password, the authentication process in the gateway device 101 cannot be successful. In this case, the gateway device 101 does not permit initial registration and update of the communication setting information by the home terminal device 32. Therefore, the home user cannot perform initial registration and update of the communication setting information held by the gateway device 101.

  For example, in a gateway device capable of resetting an ID and a corresponding password and communication setting information, the ID and the corresponding password and communication setting information can be returned to initial values by performing initialization by reset. The initial value of the ID and the initial value of the password are described in the manual of the gateway device, for example.

  Therefore, after resetting the gateway device, the home user refers to the manual, makes the authentication process successful using the initial value of the ID and the initial value of the password, and is held by the gateway device via the home terminal device 32. Initial registration and update of communication setting information can be performed.

  However, the resetting of the gateway device also returns the communication setting information to the initial value, so the in-home user needs to input the communication setting information before returning to the initial value. For example, when it is necessary to input an address or the like for each home device 33 in the communication setting information, if the number of home devices 33 in the communication system 201 is large, the burden of input by the home user becomes undesirably heavy.

  Thus, the communication system 201 and the gateway device 101 according to the embodiment of the present invention solve such problems by the following configuration and operation.

[Gateway device configuration]

  The authentication information holding unit 52 in the storage unit 49 holds, for example, a home user ID and a verification password corresponding to the ID. The communication setting information holding unit 50 can hold communication setting information.

  The web information holding unit 51 holds, for example, login web information, editing web information, and login failure web information by default.

  Here, the login web information is, for example, web information for displaying a login page of a home user who wants to change the communication setting information and the verification password shown in FIG. The editing web information is, for example, web information for indicating that the login has been successful and displaying an editing page for newly registering or updating the communication setting information and changing the verification password. The login failure web information is, for example, web information for displaying a page indicating that login failed.

  The URL of the login web information is, for example, “http: // xxxx /” (hereinafter also referred to as a login URL).

  The communication unit 41 exchanges information with the external terminal device 22 via, for example, the external network port 54 and the external network 21. In addition, the communication unit 41 exchanges information with the in-home device 33 and the in-home terminal device 32 via the in-home network port 55 and the in-home network 31, for example.

  The communication control unit 42 processes information exchanged with the home terminal device 32 via the communication unit 41, for example. Further, the communication control unit 42, for example, between the outside terminal device 22 connected to the external network 21 and the inside device 33 connected to the home network 31 based on the communication setting information in the communication setting information holding unit 50. Performs relay processing to relay information exchanged in

  The AC adapter 72 has a first end 72 </ b> A connected to the outlet 71 and a second end 72 </ b> B connected to the AC adapter insertion port 57 in the gateway device 101. For example, the AC adapter 72 converts AC power supplied from the outlet 71 into DC power, and outputs the converted DC power to the gateway device 101.

  Each unit in the gateway apparatus 101 operates using DC power received from the AC adapter 72 via the AC adapter insertion port 57.

[setting change]
The home terminal device 32 can, for example, perform initial registration and update of communication setting information held by the gateway device 101 and change of a verification password.

  More specifically, the in-home user attempts to initially register the communication setting information in the gateway device 101 in the initial state, updates the communication setting information in the gateway device 101, or uses the verification password in the gateway device 101. When the change is to be made, for example, as shown in FIG. 2, a login URL is input into the address input area 34A.

  Based on the input login URL, the home terminal device 32 transmits to the gateway device 101 a login web information request for requesting corresponding web information, that is, login web information.

  When the communication control unit 42 in the gateway device 101 receives the login web information request from the home terminal device 32 via the communication unit 41, the communication control unit 42 acquires the login web information from the web information holding unit 51, and transmits the acquired login web information to the communication unit 41. To the in-home terminal device 32.

  Upon receiving the login web information from the gateway device 101, the home terminal device 32 displays the login page shown in FIG. 2 in the page area 34B based on the received login web information.

  The home user, for example, operates the operation unit 32B based on the display of the login page shown in FIG. 2 and inputs his / her ID and password in the user ID input area 34C and password input area 34D, respectively, and then the login button Press 34E.

  The in-home terminal device 32 transmits input information based on a user operation as authentication information to the gateway device 101. Specifically, the home terminal device 32 transmits a password (hereinafter also referred to as an input password) as authentication information to the gateway device 101 based on, for example, a user operation. At this time, for example, the in-home terminal device 32 sends an editing web information request for requesting an ID input based on a user operation (hereinafter also referred to as an input ID) and editing web information. Send to.

  When the communication control unit 42 in the gateway device 101 receives, for example, the input ID, the input password, and the editing web information request from the home terminal device 32 via the communication unit 41, the communication control unit 42 sets the received input ID and input password to the setting information changing unit 43. Output to.

  The setting information changing unit 43 performs authentication processing using the authentication information, and based on the result of the authentication processing, initial registration of communication setting information or update of the communication setting information in the communication setting information holding unit 50, and a verification password Allow changes to

  Specifically, when the authentication unit 44 in the setting information changing unit 43 receives an input ID and an input password from the communication control unit 42, for example, the authentication unit 44 performs the following processing.

  That is, for example, the authentication unit 44 acquires a verification password corresponding to the input ID from the authentication information holding unit 52 in the storage unit 49 based on the input ID.

  And the authentication part 44 performs an authentication process, for example using the acquired password for collation as authentication information. Specifically, for example, the authentication unit 44 compares the verification password and the input password, and if the verification result indicates a match, the authentication unit 44 determines that the authentication is successful and notifies the permission unit 45 of the successful authentication. If the matching result does not indicate a match, it is determined that the authentication has failed, and the authentication unit is notified of the authentication failure. Note that the authentication unit 44 may perform authentication processing using, for example, a set of an ID and a verification password corresponding to the ID as authentication information.

  For example, when the permission unit 45 receives a notification of successful authentication from the authentication unit 44, the permission unit 45 permits the initial registration and update of the communication setting information and the change of the verification password, and outputs the permission information to the communication control unit 42. For example, when the permission unit 45 receives a notification of authentication failure from the authentication unit 44, the permission unit 45 does not permit the initial registration and update of the communication setting information and the change of the verification password, and outputs non-permission information to the communication control unit 42. To do.

  For example, when receiving the permission information from the permission unit 45, the communication control unit 42 acquires the editing web information from the web information holding unit 51 in response to the editing web information request, and transmits the acquired editing web information to the communication unit 41. To the in-home terminal device 32.

  Upon receiving the editing web information from the gateway device 101, the in-home terminal device 32 displays an editing page in the page area 34B based on the received editing web information. Thereby, the in-home user can perform initial registration or update of the communication setting information and change of the verification password.

  The in-home user operates the operation unit 32B to input communication setting information to be initially registered or updated or a new verification password. The in-home terminal device 32 transmits the initial registration content or updated content of the communication setting information or the new verification password to the gateway device 101 based on the user operation.

  The communication control unit 42 in the gateway device 101 acquires communication setting information. Specifically, the communication control unit 42 receives, for example, communication setting information, that is, initial registration content or update content, or a new verification password from the home terminal device 32 via the communication unit 41.

  For example, the communication control unit 42 outputs the received initial registration content or updated content, or the new verification password to the writing unit 46 in the setting information changing unit 43.

  When receiving the initial registration content from the communication control unit 42, the writing unit 46 writes the communication setting information to be initially registered in the communication setting information holding unit 50 based on the received initial registration content. Further, for example, when receiving the update content from the communication control unit 42, the writing unit 46 updates the communication setting information in the communication setting information holding unit 50 based on the received update content. For example, when the writing unit 46 receives a new verification password from the communication control unit 42, the writing unit 46 changes the corresponding verification password in the authentication information holding unit 52 to the new verification password.

  On the other hand, for example, when the communication control unit 42 receives non-permission information from the permission unit 45, the communication control unit 42 acquires login failure web information instead of acquiring the editing web information from the web information holding unit 51 in response to the editing web information request. Then, the acquired login failure web information is transmitted to the home terminal device 32 via the communication unit 41.

  Upon receiving the login failure web information from the gateway device 101, the home terminal device 32 displays a page indicating that the login has failed on the page area 34B based on the received login failure web information. Thereby, the home user recognizes that the login has failed.

[Authentication information change processing]
For example, if the in-home user does not remember the correct password corresponding to his / her ID, the user can change the verification password without changing the communication setting information in the gateway device 101.

  More specifically, the authentication information change processing unit 48 in the gateway device 101 changes the authentication information used for the authentication process, that is, the verification password without changing the communication setting information held in the communication setting information holding unit 50. Perform authentication information change processing.

  For example, the authentication information change processing unit 48 starts the authentication information change process when a predetermined operation is performed on the INIT button 63 that can accept a user operation. The INIT button 63 is a button for causing the gateway apparatus 101 to execute initialization, for example. Note that the authentication information change processing unit 48 may start the authentication information change process when a predetermined operation is performed on a button other than the INIT button 63.

  Specifically, the authentication information change processing unit 48 starts the authentication information change process when, for example, the INIT button 63 is continuously pressed by the home user for a predetermined time Tb.

  More specifically, the authentication information change unit 61 in the authentication information change processing unit 48 monitors the state of the INIT button 63, for example. For example, when the INIT button 63 is pressed, the authentication information changing unit 61 sets the timer 64 so that it expires after a predetermined time Tb.

  For example, when the INIT button 63 is continuously pressed until the timer 64 expires, the authentication information changing unit 61 changes the operation mode of the gateway device 101 from the normal mode to the password generation mode.

  For example, when the operation mode is changed to the password generation mode, the authentication information changing unit 61 sets the timer 64 so as to expire after a predetermined time Tp. Then, for example, the authentication information change unit 61 performs an authentication information change process during a period from when the operation mode is changed to the password generation mode until it is returned to the normal mode (hereinafter also referred to as a password generation period).

  Specifically, the authentication information changing unit 61 causes the lamp 62 to blink in the password generation period, for example.

  FIG. 6 is a diagram showing another example of a screen displayed on the display unit of the home terminal device according to the embodiment of the present invention.

  Referring to FIG. 6, authentication information changing unit 61 holds password transmission web information, for example, and web information holding unit 51 so that a home user can access password transmission web information during the password generation period. Temporarily save password transmitted web information. For example, the authentication information changing unit 61 stores password transmission web information in the web information holding unit 51 by default, and performs control to give the home user permission to access the password transmission web information during the password generation period. May be.

  Here, the password transmission web information is, for example, web information for displaying the password transmission page shown in FIG. The URL of the password transmission web information is, for example, “http: // xxxx / yyy” (hereinafter also referred to as a password transmission URL). The password transmission URL is described in the manual of the gateway device 101, for example. Note that the gateway device 101 may be configured such that, for example, a password transmission URL is displayed on a display unit (not shown) of the gateway device 101.

  For example, when the home user confirms that the lamp 62 in the gateway device 101 is blinking, the home user recognizes that the gateway device 101 has transitioned to the password generation mode, and refers to the manual described above to reference the address input area 34A in the web browser 34. Enter the password transmission URL.

  Based on the input password transmission URL, the home terminal device 32 transmits a password transmission web information request for requesting web information corresponding to the gateway device 101, that is, password transmission web information.

  When the communication control unit 42 in the gateway device 101 receives the password transmission web information request from the home terminal device 32 via the communication unit 41, the communication control unit 42 acquires the password transmission web information from the web information holding unit 51 and uses the acquired password transmission web information. The data is transmitted to the home terminal device 32 via the communication unit 41.

  When receiving the password transmission web information from the gateway device 101, the home terminal device 32 displays the password transmission page shown in FIG. 6 in the page area 34B based on the received password transmission web information.

  Note that the communication control unit 42 may transmit, for example, a registered e-mail address that is an e-mail address registered in advance by the in-house user to the in-home terminal device 32 together with the password transmission web information. This registered e-mail address is, for example, an e-mail address that can be received by a home user, and is held in the e-mail address holding unit 53. In this case, for example, the home terminal device 32 displays the registered email address received from the gateway device 101 in the email address input area 34F in the password transmission page shown in FIG. This registered e-mail address may be editable or may not be editable.

  For example, the home user operates the operation unit 32B based on the display of the password transmission page shown in FIG. Push.

  The in-home terminal device 32 transmits the input e-mail address (hereinafter also referred to as input e-mail address) to the gateway device 101 based on the operation of the in-home user.

  When the communication control unit 42 in the gateway device 101 receives the input mail address from the home terminal device 32 via the communication unit 41, the communication control unit 42 outputs the received input mail address to the authentication information changing unit 61.

  For example, in the authentication information change process, the authentication information changing unit 61 acquires destination information of a specific device from another device, specifically, the home terminal device 32, and uses the acquired destination information to obtain temporary authentication information. Send to a specific device.

  More specifically, the authentication information changing unit 61 receives an input mail address from the communication control unit 42 as destination information of a specific device, for example. Here, the specific device is, for example, a mail server having an input mail address.

  In the gateway device 101, the authentication information changing unit 61 is configured to receive, that is, acquire, the destination information of a specific device from the home terminal device 32. However, the configuration is not limited thereto. For example, the gateway device 101 may include a receiving unit that receives a direct input from a home user, and may acquire the destination information of a specific device via the receiving unit.

  Then, for example, the authentication information changing unit 61 randomly generates a temporary verification password as temporary authentication information, and stores the generated temporary verification password in the authentication information holding unit 52 instead of the corresponding verification password. Note that the authentication information changing unit 61 may store the generated temporary verification password in the authentication information holding unit 52 while leaving the corresponding verification password, for example. Further, the authentication information changing unit 61 may use default information as temporary authentication information, for example.

  For example, the authentication information changing unit 61 creates a mail including the generated temporary verification password and whose destination is the input mail address (hereinafter also referred to as a notification mail), and sends the created notification mail to the communication control unit 42. At the same time, the operation mode is returned from the password generation mode to the normal mode. The password generation period ends when the operation mode returns from the password generation mode to the normal mode.

  Note that the authentication information changing unit 61 may store the input email address in the email address holding unit 53 when outputting the notification email to the communication control unit 42, for example. The input e-mail address stored in the e-mail address holding unit 53 can be used as a transmission history of the temporary verification password. Since the user who has received the temporary verification password can be specified based on this transmission history, the security of the gateway apparatus 101 can be improved from the software viewpoint.

  For example, when the timer 64 expires before the notification mail is transmitted via the communication control unit 42, the authentication information changing unit 61 returns the operation mode from the password generation mode to the normal mode.

  For example, when receiving a notification mail from the authentication information changing unit 61, the communication control unit 42 transmits the received notification mail to the mail server indicated by the input mail address via the communication unit 41.

  The home user operates, for example, the home terminal device 32 or a wireless terminal device such as a mobile phone and a smartphone, and causes the home terminal device 32 or the wireless terminal device to obtain a notification mail from the mail server. The home user acquires a temporary verification password by referring to the content of the notification mail acquired by the home terminal device 32 or the wireless terminal device, for example.

  Then, for example, the in-home user displays the login page shown in FIG. 2 on the in-home terminal device 32 using the login URL, and the user ID input area 34C and the password input area 34D have their own ID and the acquired temporary verification password. Each is input and the login button 34E is pushed.

  The in-home terminal device 32 transmits input information based on a user operation as authentication information to the gateway device 101. Specifically, the in-home terminal device 32, for example, inputs input information, that is, a temporary verification password (hereinafter also referred to as an input temporary verification password) together with an input ID and an editing web information request based on a user operation. Transmit to the gateway device 101.

  When the communication control unit 42 in the gateway device 101 receives the input ID, the input temporary verification password, and the editing web information request from the home terminal device 32 via the communication unit 41, the communication control unit 42 sets the received input ID and input temporary verification password. It outputs to the information change part 43.

  The setting information changing unit 43 performs an authentication process using the temporary authentication information. Specifically, for example, the setting information changing unit 43 performs communication when the input information received from the home terminal device 32 matches the temporary authentication information, that is, when the input temporary verification password matches the temporary verification password. The initial registration of the communication setting information or the update of the communication setting information in the setting information holding unit 50 and the change of the verification password are permitted.

  More specifically, when the authentication unit 44 in the setting information changing unit 43 receives an input ID and an input temporary verification password from the communication control unit 42, for example, the authentication information 44 is changed from the authentication information holding unit 52 in the storage unit 49 to the input ID. A corresponding password, that is, a temporary verification password is acquired.

  Then, for example, the authentication unit 44 compares the acquired temporary verification password and the input temporary verification password, and if the verification result indicates a match, the authentication unit 44 determines that the authentication has succeeded and notifies the permission unit 45 of successful authentication. If the matching result does not indicate a match, it is determined that the authentication has failed, and the authentication unit is notified of the authentication failure.

  For example, when the permission unit 45 receives a notification of successful authentication from the authentication unit 44, the permission unit 45 permits the initial registration and update of the communication setting information and the change of the verification password, and outputs the permission information to the communication control unit 42. For example, when the permission unit 45 receives a notification of authentication failure from the authentication unit 44, the permission unit 45 does not permit the initial registration and update of the communication setting information and the change of the verification password, and outputs non-permission information to the communication control unit 42. To do.

  In this way, the home user remembers the correct password by changing the verification password used for the authentication process to the temporary verification password without changing the communication setting information held in the communication setting information holding unit 50. Even if not, the authentication process can be successful using the temporary verification password, so that the initial registration and update of the communication setting information held by the gateway apparatus 101 and the verification password can be changed.

  The authentication information change processing unit 48 is configured to start the authentication information change process when the predetermined time Tb and the INIT button 63 are continuously pressed. However, the present invention is not limited to this. For example, the authentication information change processing unit 48 may be configured to start the authentication information change processing when a predetermined operation is performed on the INIT button 63 and the AC adapter insertion port 57 as the operation unit.

  More specifically, the authentication information change unit 61 in the authentication information change processing unit 48 is configured so that, for example, a home user connects the second end 72B of the AC adapter 72 with the first end 72A connected to the outlet 71 to the AC adapter insertion port 57. When DC power is supplied to the gateway apparatus 101 and its own operation starts, the following processing is performed.

  That is, for example, the authentication information changing unit 61 turns on the lamp 62, sets the timer 64 so as to expire after a predetermined time Ta, and monitors the state of the INIT button 63.

  For example, when the INIT button 63 is continuously pressed until the timer 64 expires, the authentication information changing unit 61 changes the operation mode of the gateway device 101 from the normal mode to the password generation mode and turns off the lamp 62. Thereafter, the lamp 62 is blinked.

  In other words, the authentication information changing unit 61 inserts the second end 72B of the AC adapter 72 with the first end 72A connected to the outlet 71 into the AC adapter insertion port 57 while the home user presses the INIT button 63, for example. Thereafter, the authentication information change process is started when the INIT button 63 is continuously pressed until the lamp 62 is turned on and then turned off after a predetermined time Ta.

  In the above case, instead of the home user inserting the second end 72B of the AC adapter 72 having the first end 72A connected to the outlet 71 into the AC adapter insertion port 57, the second end 72B is connected to the AC adapter insertion port 57. Inserting the first end 72 </ b> A of the AC adapter 72 connected to 57 into the outlet 71 may be a start condition for the authentication information change process.

  Further, the authentication information change processing unit 48 is not limited to the configuration in which the authentication information change process is started when a predetermined operation is performed on the INIT button 63, but a user other than the INIT button 63, such as a button, a switch, and a touch panel Any configuration may be used as long as authentication information change processing is started when a predetermined operation is performed on a component that can accept this operation.

[Modification 1]
In the gateway device according to the embodiment of the present invention, the authentication information changing unit 61 is configured to transmit the temporary verification password to the specific device in the authentication information changing process. However, the present invention is not limited to this. . The authentication information changing unit 61 may be configured to delete the verification password in the authentication information changing process.

  More specifically, for example, when the authentication information changing process is started, the authentication information changing unit 61 changes the operation mode of the gateway apparatus 101 from the normal mode to the password erasing mode.

  For example, when the operation mode is changed to the password erasing mode, the authentication information changing unit 61 causes the lamp 62 to blink in the password erasing period. Here, the password erasure period is the same as the password generation period described above.

  For example, the authentication information changing unit 61 holds password erasure web information, and the password information web information is temporarily stored in the web information holding unit 51 so that a home user can access the password erasure web information during the password erasure period. Save the data.

  Here, the password deletion web information is, for example, web information for displaying a password deletion page including a password deletion button for starting password deletion. For example, the URL of the password deletion web information is the same as the URL of the password transmission web information.

  For example, when the home user visually recognizes that the lamp 62 in the gateway device 101 is blinking, the user recognizes that the gateway device 101 has transitioned to the password deletion mode, and inputs the password deletion URL in the address input area 34A of the web browser 34. To do.

  Based on the input password erasure URL, the home terminal device 32 transmits a password erasure web information request for requesting password erasure web information to the gateway device 101, and receives the password erasure web information from the gateway device 101. The password erase page is displayed in the page area 34B.

  For example, the home user refers to the password deletion page, operates the operation unit 32B, and presses the password deletion button. The home terminal device 32 transmits a password deletion command and a web information request for editing to the gateway device 101 based on the operation of the home user.

  For example, when the communication control unit 42 in the gateway device 101 receives a password deletion command and an editing web information request from the home terminal device 32 via the communication unit 41, the communication control unit 42 outputs the password deletion command to the authentication information change unit 61.

  For example, when receiving a password deletion command from the communication control unit 42, the authentication information changing unit 61 deletes the verification password in the authentication information holding unit 52 and notifies the communication control unit 42 of a password deletion completion notification.

  For example, when the communication control unit 42 receives a password deletion completion notification from the authentication information changing unit 61, the editing web in which the functions other than the verification password changing function are limited among the functions included in the editing web information described above. Information is transmitted to the home terminal device 32 via the communication unit 41.

  Upon receipt of the editing web information from the gateway device 101, the in-home terminal device 32 is based on the received editing web information, and the editing page in which the login success display function and the communication registration information new registration function and update function are limited. Is displayed in the page area 34B. As a result, the verification password can be changed. Specifically, the previous verification password can be erased and a new verification password can be set, so that the home user can set the communication using the new verification password. Information can be changed.

[Modification 2]
Although the gateway apparatus 101 according to the embodiment of the present invention is configured to set the URL of the password transmission web information to a predetermined URL, the present invention is not limited to this. The gateway device 101 may be configured to randomly set the URL of the password transmission web information.

  More specifically, the authentication information change unit 61 in the authentication information change processing unit 48 changes the operation mode of the gateway apparatus 101 from the normal mode to the password generation mode, for example, when the authentication information change process is started.

  For example, when the operation mode is changed to the password generation mode, the authentication information changing unit 61 blinks the lamp 62 and randomly generates the URL of the password transmission web information during the password generation period. Hereinafter, the URL of the password transmission web information generated at random is also referred to as a random URL.

  Then, for example, the authentication information changing unit 61 creates a mail including the generated random URL and whose destination is the above-described registered mail address (hereinafter also referred to as a URL notification mail), and communicates the created URL notification mail. The data is transmitted to the mail server indicated by the registered mail address via the control unit 42 and the communication unit 41.

  The home user operates the home terminal device 32 or the wireless terminal device, for example, and causes the home terminal device 32 or the wireless terminal device to acquire a URL notification mail from the mail server. For example, the home user refers to the content of the URL notification mail acquired by the home terminal device 32 or the wireless terminal device, and acquires a random URL.

  The home user inputs the acquired random URL into the address input area 34 </ b> A of the web browser 34.

  The home terminal device 32 transmits a password transmission web information request to the gateway device 101 based on the input random URL, and when receiving the password transmission web information from the gateway device 101, displays the password transmission page in the page area 34B. .

  Although the gateway device according to the embodiment of the present invention is configured to hold communication setting information for communicating with the out-of-home terminal device 22 and the in-home device 33, the present invention is not limited to this. The gateway device 101 may be configured to hold communication setting information for communicating with either the out-of-home terminal device 22 or the in-home device 33. Further, the gateway device 101 may be configured to hold communication setting information for communicating with the home terminal device 32.

  In addition, the gateway device according to the embodiment of the present invention is configured to perform initial registration and update of the communication setting information. However, the present invention is not limited to this. The gateway device 101 may be configured to perform either one of initial registration and update of communication setting information.

  Moreover, although the gateway device according to the embodiment of the present invention is configured to transmit temporary authentication information to a mail server, the present invention is not limited to this. The gateway device 101 may be configured to transmit temporary authentication information to devices such as the home terminal device 32 other than the mail server.

  In addition, the gateway device according to the embodiment of the present invention is configured to receive destination information from another device and transmit temporary authentication information to a specific device using the received destination information. It is not limited. The gateway device 101 may be configured to hold destination information of a specific device in advance and transmit temporary authentication information to the specific device using the held destination information.

  By the way, in a gateway device that performs authentication processing using authentication information such as a password, for example, when a user forgets a password, a method of returning the password to the initial password by resetting the gateway device is conceivable. In this case, there is a high possibility that settings other than the password will be initialized in the gateway device. When settings other than the password are initialized, the user must perform an operation for returning the settings other than the password to the settings before the reset.

  In contrast, in the gateway device according to the embodiment of the present invention, the communication setting information holding unit 50 holds communication setting information for communicating with the out-of-home terminal device 22 and the in-home device 33. The setting information changing unit 43 performs an authentication process using the verification password, and based on the result of the authentication process, initial registration of communication setting information in the communication setting information holding unit 50 or setting information in the communication setting information holding unit 50 Allow update.

Further, for example, when a home user using the home terminal device 32 sets destination information and the set destination information can be transmitted from the home terminal device 32 to the gateway device 101, the destination of the temporary verification password is set in the home user. It can be set in the lead.

  In the communication system according to the embodiment of the present invention, gateway device 101 transmits a temporary verification password to the mail server. The in-home terminal device 32 transmits input information based on a user operation as authentication information to the gateway device 101. When the input information received from the home terminal device 32 matches the temporary verification password, the gateway device 101 permits initial registration or update of the communication setting information.

  With this configuration, the home user who has acquired the temporary verification password from the mail server can receive initial registration or update permission of the communication setting information using the acquired temporary verification password. Communication setting information can be protected against changes to

  In addition, since users who can acquire a temporary verification password can be limited to specific users who can acquire a temporary verification password from the mail server, users other than the specific user can successfully perform authentication processing. Can be prevented. Thereby, the security of the gateway apparatus 101 can be improved from the software side.

  In the communication system according to the embodiment of the present invention, the gateway device 101 acquires the destination information of the mail server from the home terminal device 32. Then, the gateway apparatus 101 transmits a temporary verification password to the mail server using the acquired destination information.

  With such a configuration, the temporary verification password can be reliably transmitted to the mail server having the destination information based on the acquired destination information. Further, for example, when a home user using the home terminal device 32 sets destination information and the set destination information can be transmitted from the home terminal device 32 to the gateway device 101, the destination of the temporary verification password is set in the home user. It can be set in the lead.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
