(Embodiment)
[1. Authentication system)
FIG. 1 is a diagram illustrating an authentication system according to an embodiment. An authentication system 1 shown in FIG. 1 is, for example, a HEMS (Home Energy Management System) network to which electrical devices are connected that conforms to the ECHONET or ECHONET Lite protocol.

  As shown in FIG. 1, the authentication system 1 includes a residential distribution board HD, a smart meter MT, a home gateway GW, a doorphone parent device 10, a doorphone slave device 30, a doorphone server 100, and a management server 200. It comprises.

  In the authentication system 1 shown in FIG. 1, the door phone server 100 and the management server 200 are connected to the Internet. In the authentication system 1 shown in FIG. 1, the doorphone master unit 10 and the doorphone slave unit 30 are connected to the Internet using the HEMS home gateway GW as a gateway. Therefore, in the authentication system 1 shown in FIG. 1, for example, information can be transmitted and received between the doorphone parent device 10, the doorphone child device 30, the doorphone server 100, and the management server 200.

  The residential distribution board HD is a device that divides electricity into the wiring of the house 2. For example, the residential distribution board HD includes various devices such as an earth leakage breaker and a wiring breaker. For example, the residential distribution board HD supplies power supplied from the power system CP to the general load NL of the house 2. In addition, the house 2 concerning embodiment shall be one room of a predetermined apartment.

  The smart meter MT is a meter that measures the power supplied from the power system CP, that is, the power purchased from the power system CP, and the power supplied to the power system CP, that is, the sold power. That is, the smart meter MT holds information regarding the power supplied to the power system CP. For example, the smart meter MT may include a meter that measures the sold power and a meter that measures the purchased power. For example, as shown in FIG. 1, the smart meter MT is provided between the residential distribution board HD and the power system CT, and measures the sold power or the purchased power.

  Further, the smart meter MT can transmit each information to the management server 200 via the home gateway GW. For example, in response to a request from the management server 200, the smart meter MT transmits data related to power consumption consumed in the house 2 via the home gateway GW.

  The home gateway GW is a network device that enables transmission and reception of information between the networks of the authentication system 1. The home gateway GW enables transmission / reception of information between the components of the authentication system 1. For example, the home gateway GW enables transmission / reception of information between the door phone server 100 and the management server 200. A predetermined relay device (for example, a broadband router) or the like may be provided between the home gateway GW and the door phone server 100 and the management server 200, but the description is omitted in FIG.

  Also, the doorphone parent device 10 connected to the Internet via the home gateway GW has a doorphone child device 30. Further, the doorphone master unit 10 and the doorphone slave unit 30 are installed in the house 2. Although FIG. 1 shows an example in which one set of doorphone parent device 10 and doorphone child device 30 is set for each house 2 which is a residence room of a predetermined apartment, a plurality of sets of doorphone parent devices 10 and The door phone slave unit 30 may be installed. Moreover, although there are a plurality of houses 2 in which the doorphone master unit 10 and the doorphone slave unit 30 are installed, a plurality of illustrations are omitted in FIG. Note that the doorphone master unit 10 and the doorphone slave unit 30 may be collectively referred to as a doorphone device.

  When the visitor operates the doorphone slave unit 30, the doorphone master unit 10 receives a visitor notification from the doorphone slave unit 30. When the doorphone master unit 10 receives the visitor notification, the doorphone master unit 10 outputs a predetermined voice for notification of the visitor such as a chime or a melody from the speaker. Thereby, door phone main unit 10 notifies a visitor to the person at home. Furthermore, door phone master unit 10 receives a moving image captured by a camera (not shown) of door phone slave unit 30 from door phone slave unit 30. Then, the intercom base unit 10 displays the received moving image on the display unit 12. As a result, door phone master unit 10 provides the operator of door phone master unit 10 with the type of person who has visited. The display unit 12 corresponds to a monitor (display screen) included in the door phone base unit 10. The display unit 12 is assumed to employ a touch panel.

  The operator confirms the moving image displayed on the display unit 12 and presses the response button 13 when responding. When the response button 13 is pressed, the doorphone master unit 10 connects the microphone and speaker of the doorphone slave unit 30 to the microphone and speaker of the doorphone master unit 10, and operates the doorphone master unit 10 and the doorphone slave unit 30. Enable people to talk.

  The door phone slave unit 30 has a call button 31. Also, the door phone slave unit 30 has a microphone and a speaker (not shown).

  A customer who has visited the house 2 presses the call button 31 of the door phone slave unit 30 and notifies the home visitor. When the call button 31 is pressed, the doorphone slave device 30 notifies the doorphone master device 10 of a visitor notification. Thereafter, the response button 13 of the doorphone master unit 10 is pressed to connect to the microphone and the speaker of the doorphone slave unit 30, and the customer uses the doorphone slave unit 30 to talk to the operator of the doorphone master unit 10. Can do.

  Here, for example, the door phone installer installs the door phone device according to the embodiment in a newly built apartment. Further, a management company that manages the management server 200 connects the intercom base unit 10 and the home gateway GW. Further, the manager registers information (hereinafter, referred to as “device information”) that can identify the door phone device installed in each house 2 of each condominium with the management server 200 (device registration). For example, if the condominium ID is identification information for identifying a condominium, and the condominium identified by the condominium ID is composed of a plurality of ridges, the management company has ridge information (for example, ridge number) for identifying the ridge, The information associated with the room number in which the door phone device is installed is registered in the management server 200 as device information.

  For example, it is assumed that the house 2 shown in FIG. 1 is the “101” room in the “A” ridge of the apartment name “ABC”. Further, it is assumed that the apartment ID of the apartment “ABC” is “0001” in advance. In such a case, the management company registers “apartment ID: 0001, building information: A, room number: 101” in the management server 200 as device information for identifying the intercom base unit 10 installed in the house 2. Further, the management company registers the apartment name “ABC” in association with the device information.

  With the device information registered in the management server 200 in this way, the house 2 is handed over to the resident. In such a state, the resident of the house 2 registers in the management server 200 that he / she is a user of the doorphone master unit 10. Such registration corresponds to member registration for registering that the resident person belongs to the authentication system 1 (HEMS) shown in FIG.

  For example, the user (resident of the house 2) accesses a dedicated site for member registration using the terminal device T such as a smartphone, a mobile phone terminal, a tablet terminal, etc., and the above-mentioned manon ID, apartment name, building information, room number. Complete membership registration by entering member information including The dedicated site may be distributed by the management server 200, or may be distributed from a predetermined server related to the door phone server 100 or the management server 200. In addition, since the member information used for member registration and the device information registered in advance in the management server 200 are the same, they may be collectively referred to as “registration information” below.

  The management server 200 authenticates the door phone device installed in the house 2. Specifically, the management server 200 authenticates that the procedure for linking the doorphone master unit 10 with the own device (management server 200) has been normally performed by the user of the doorphone device installed in the house 2. Perform the authentication process.

  Then, when authentication is obtained by the authentication process, the management server 200 transmits data regarding power consumption to the doorphone server 100 so as to be displayed on the display unit 12 of the doorphone master unit 10. From the above, it can be said that the management server 200 is a device that transmits data related to power consumption to the doorphone server 100 on the condition that authentication is obtained.

  Moreover, the management server 200 acquires the data regarding power consumption from the smart meter MT so that the data regarding power consumption can be transmitted to the door phone server 200, for example, as shown in FIG. For example, the management server 200 acquires data regarding power consumption from the smart meter MT via the home gateway GW by periodically transmitting an acquisition request to the smart meter MT via the home gateway GW. In addition, the management server 200 accumulates and manages the acquired data regarding power consumption as a power consumption history.

  In addition, when the user has registered as a member, the management server 200 issues a member number and transmits the issued member number to the user terminal device T.

  Now, the authentication process performed by the authentication system 1 according to the embodiment will be specifically described below. In the following description, the resident of the house 2 is described as a “user” of the doorphone master unit 10. In addition, it is assumed that the user has performed the member registration described above.

  For example, it is assumed that the user wants the display unit 12 of the door phone master unit 10 to display data related to the power consumption consumed in his / her house 2. In such a case, for example, the user performs a selection operation to display data related to power consumption on the display unit 12 that employs a touch panel.

  When receiving the selection operation from the user, door phone base unit 10 transmits registration information used for member registration, that is, device information of the device registered in advance in management server 200 to door phone server 100 via home gateway GW. (Step S11). For example, the doorphone base unit 10 transmits the apartment information, the building information, and the room number as device information to the doorphone server 100 via the home gateway GW. The doorphone master unit 10 may also transmit the apartment name.

  For example, it is assumed that the doorphone master unit 10 is installed in the “101” room in the “A” ridge of the apartment “ABC” identified by the apartment ID “0001”. In this case, door phone base unit 10 associates apartment ID “0001”, building information “A” building, and room number “101”, and transmits the result to door phone server 100 via home gateway GW.

  Then, door phone server 100 receives registration information from door phone parent device 10. Here, it is assumed that the door phone server 100 determines that the management server 200 has not obtained authentication of cooperation between the registration information transmission source door phone parent device 10 and the management server 200. In such a case, door phone server 100 requests management server 200 to perform authentication processing (step S12). For example, door phone server 100 transmits a request including registration information received from door phone parent device 10 to management server 200.

  Then, the management server 200 receives a request from the door phone server 100. Here, the management server 200 searches the registration information storage unit 221 so that the user of the registration information transmission source intercom base unit 10 does not perform the cooperation procedure, that is, the cooperation authentication is not obtained. Suppose you confirm.

  In such a case, the management server 200 generates an authentication code used in the cooperation procedure (step S13). Then, the management server 200 transmits the generated authentication code to the door phone server 100 (step S14). For example, as described above, when the management server 200 is authenticated that the user of the doorphone master unit 10 that is the registration information transmission source has registered as a member, the management server 200 generates the member number together with the member number issued at the time of member registration. The authentication code is sent to the door phone server. As a result, the management server 200 indicates that the user of the doorphone master unit 10 that is the registration information transmission source is currently registered as a member, but the cooperation authentication is not obtained because the cooperation procedure is not performed. Notify

  The management server 200 generates an authentication code and transmits a QR code (registered trademark), which is a two-dimensional code including the generated authentication code, to the doorphone server 100, so that the QR code is displayed on the doorphone base unit 10. It may be displayed on the part 12. This will be described in detail later. The management server 200 may employ any two-dimensional code other than the QR code.

  Door phone server 100 receives an authentication code from management server 200. Then, the door phone server 100 transmits the received authentication code to the door phone parent machine 10 via the home gateway GW (step S15). Then, intercom base unit 10 causes display unit 12 to display the received authentication code.

  In other words, if the user has not performed the procedure for linking the doorphone master unit 10 and the management server 200 and the management server 200 has not obtained the authentication for cooperation, the data regarding the power consumption is not displayed. Instead, an authentication code used in the cooperation procedure is displayed on the display unit 12.

  Here, the user uses his / her terminal device T to perform a procedure for linking the intercom base unit 10 and the management server 200. Specifically, the user accesses a web page for inputting the authentication code displayed on the display unit 12. Then, the user inputs the authentication code and, for example, presses a transmission button displayed on the web page, thereby causing the terminal device T to transmit the authentication code to the management server 200 (step S16). The URL of the web page for inputting the authentication code may be displayed on the display unit 12 together with the authentication code.

  Further, the user can more easily perform the cooperation procedure by using the QR code generated by the management server 200. For example, when the management server 200 generates not only the authentication code but also the QR code including the authentication code as described above, the management server 200 causes the display unit 12 to display the generated authentication code and QR code.

  Here, the user causes the terminal device T to read the QR code using the QR code reading function of the camera of the terminal device T. In such a case, the terminal device T displays a web page in which the authentication code included in the QR code is automatically input according to the control information included in the QR code. For example, when a transmission button displayed on the web page is pressed, the terminal device T transmits an authentication code to the management server 200.

  When the management server 200 receives the authentication code from the terminal device T, the management server 200 performs an authentication process using the authentication code (step S17). Specifically, the management server 200 refers to the registration information storage unit 221 and searches for registration information associated with the received authentication code. When the registration information exists, the management server 200 authenticates the cooperation between the intercom base unit 10 identified by the registration information and the own device.

  Moreover, if the management server 200 authenticates cooperation, the management server 200 will transmit the data regarding the power consumption in the house 2 where the doorphone main unit 10 of the registration information transmission source is installed to the doorphone server 100 (step S18). In addition, the management server 200 registers the registration information (condominium ID, building information, room number) of the doorphone master unit 10, and the member number, the apartment name, and the power consumption data associated with the doorphone master unit 10. The identification information of the smart meter MT that is the transmission source of is transmitted to the door phone server 100.

  The intercom server 100 recognizes that cooperation authentication has been obtained by receiving the above-described various pieces of information from the management server 200. Moreover, the door phone server 200 stores the above-described various types of information in the authentication information storage unit 121 described later. Further, the door phone server 100 generates a power graph indicating a change in power consumption based on the data regarding power consumption received from the management server 200 (step S19). For example, when the user designates to display a change in power consumption on the current day, the doorphone server 100 indicates the power indicating the change in power consumption on the current day based on the data related to the power consumption received from the management server 200. Create a graph.

  And the door phone server 100 transmits to the door phone main unit 10 via the home gateway GW so as to display the generated power graph (step S20). Then, door phone base unit 10 causes display unit 12 to display the received power graph. The door phone server 100 may also transmit the generated power graph to the terminal device T. That is, in this embodiment, the terminal device may refer not only to the doorphone parent device 10 but also to the terminal device T.

In order to register the information in 200, the member information is transmitted using the terminal device T. The member information includes, for example, Mangyeong ID, apartment name, building information, room number, and the like.

  And the member information reception part 231 searches whether the member information received from the terminal device T is memorize | stored in the registration information storage part 221 as apparatus information. When the member information received from the terminal device T is stored in the registration information storage unit 221 as device information, the member information receiving unit 231 completes the member registration by issuing a member number. Further, the member information receiving unit 231 notifies the fact that the member information is completed by transmitting the member information received from the terminal device T and the issued member number in association with each other to the door phone server 100. The member information receiving unit 231 may notify the issued member number to the terminal device T that is the member information transmission source.

  This point will be described with reference to FIG. Assume that the member information receiving unit 231 receives “condominium ID: 0001, building information: A, room number: 101” as member information from the terminal device T. Then, the member information reception unit 231 searches the registration information storage unit 221 and issues a member number “U001” when the member information is stored as device information. Then, the member information reception unit 231 stores the issued member number “U001” in the registration information storage unit 221. In addition, the member information receiving unit 231 associates “condominium ID: 0001, ridge information: A, room number: 101” with the member number “U001” and transmits them to the door phone server 100. The doorphone server 100 can recognize that the user of the corresponding doorphone master unit 10 has registered as a member by receiving the registration information and the member number.

(Registration information reception unit 232)
The registration information receiving unit 232 receives registration information from the doorphone parent device 10 via the doorphone server 100 when authentication of cooperation between the doorphone parent device 10 and the management server 200 is not obtained.

  As described with reference to FIG. 1, first, the door phone server 100 receives condominium ID, building information, and registration information used for member registration from the door phone parent device 10 that has received a selection operation for displaying data regarding power consumption. Accept room number. When the management server 200 determines that the authentication of cooperation between the registration information transmission source intercom base unit 10 and the management server 200 is not obtained by the management server 200, the door phone server 100 authenticates the management server 200. Request to process. For example, door phone server 200 transmits a request including registration information received from door phone parent device 10 to management server 200. Thereby, the registration information receiving unit 232 receives a request including registration information from the door phone server 200 from the door phone server 100.

(About the authentication unit 233)
The authentication unit 233 uses the registration information received by the registration information reception unit 232 to perform an authentication process for authenticating that the cooperation procedure has been normally performed by the user of the doorphone parent device 10 that is the registration information transmission source. Do.

  First, the authentication unit 233 refers to the registration information storage unit 221 and confirms the cooperative authentication tag associated with the registration information received by the registration information reception unit 232. The authentication unit 233 generates an authentication code for the authentication code generation unit 234 when confirming that “0” indicating that cooperation authentication is not obtained is input as the cooperation authentication tag. Instruct. Note that the authentication unit 233 may transmit a predetermined error code indicating that cooperation authentication is not obtained to the door phone server 100. Further, the error code may be transmitted to the door phone server 100 by the authentication unit 233.

  The authentication unit 233 is an authentication code generated by the authentication code generation unit 234 and accepts an input of the authentication code presented to the user by the display unit 12 of the intercom base phone 10 that is the registration information transmission source. For example, the authentication unit 233 receives the input of the authentication code from the user of the doorphone parent device 10 that is the registration information transmission source via a web page for inputting the authentication code.

  For example, the user performs a procedure for linking the intercom base unit 10 and the management server 200 using his / her terminal device T. Specifically, the user accesses a web page for inputting the authentication code displayed on the display unit 12. Then, the user inputs the authentication code and, for example, presses a transmission button displayed on the web page, and transmits the authentication code to the management server 200.

  Here, the authentication unit 233 determines whether the authentication code input by the user matches the authentication code generated by the authentication code generation unit 234. Since the authentication code generated by the authentication code generation unit 234 is stored in the registration information storage unit 221, the authentication unit 233 searches the registration information storage unit 221 for the authentication code input by the user. When the authentication unit 233 finds an authentication code input by the user, the authentication unit 233 obtains a match between the authentication code input by the user and the authentication code generated by the authentication code generation unit 234. Accordingly, the authentication unit 233 authenticates that the procedure for linking the intercom base unit 10 and the management server 200 has been normally performed by the user. That is, the authentication unit 233 authenticates the cooperation between the intercom base unit 10 and the management server 200.

(Regarding the authentication code generation unit 234)
In response to an instruction from the authentication unit 233, the authentication code generation unit 234 generates an authentication code that is used in a procedure for linking the intercom base unit 10 and the management server 200. For example, as shown in FIG. 3, the authentication code generation unit 234 generates a total 16-digit number obtained by dividing a 4-digit number with a hyphen as an authentication code, and stores the generated authentication code in the registration information storage unit 221. The authentication code generation unit 234 also stores the date and time when the authentication code was generated in the registration information storage unit 221.

  For example, when the authentication unit 233 has not obtained authentication of the doorphone master unit 10 identified by “apartment ID: 0001, ridge information: A, room number: 101”, the doorphone server 100 performs authentication processing. Suppose you receive a request. In this case, the authentication unit 233 outputs “apartment ID: 0001, ridge information: A, room number: 101” to the authentication code generation unit 234. Accordingly, the authentication unit 233 instructs to generate an authentication code used for a procedure for causing the management server 200 to cooperate with the doorphone parent device 10 identified by “condominium ID: 0001, building information: A, room number: 101”. To do.

  Upon receiving such an instruction, the authentication code generation unit 234 generates an authentication code “0011-0002-0003-0004” as shown in FIG. 3, for example. Further, the authentication code generation unit 234 stores this authentication code in the registration information storage unit 221 in association with “condominium ID: 0001, building information: A, room number: 101”. If the date and time when this authentication code is generated is “May 1, 2016 13:00”, the authentication code generation unit 234 sets the generation date and time to “condominium ID: 0001, building information: A, room number: The registration information is stored in the registration information storage unit 221 in association with “101”.

  Moreover, the authentication code production | generation part 234 changes the authentication code displayed with respect to the same doorphone main unit 10 every predetermined time progress. For example, after “30 minutes” or more have elapsed since the authentication code generation unit 234 has generated an authentication code to be displayed on a certain doorphone base unit 10, the registration information reception unit 232 again causes the same doorphone base unit 10 to Suppose that registration information is accepted. In such a situation, for example, the user of the doorphone master unit 10 tries to display the power information on the display unit 12 of the doorphone master unit 10 even though the cooperation procedure is not performed, and the display unit 12 again. Can occur by manipulating Then, the authentication code generation unit 234 generates an authentication code different from the authentication code generated last time when “30 minutes” or more have elapsed since the generation of the previous authentication code. This point will be described using an example.

  For example, as in the above example, the authentication code “0011-0002-0003-0004” is used as the authentication code displayed on the intercom base unit 10 identified by “apartment ID: 0001, building information: A, room number: 101”. ”Is generated at“ 13:00 on May 1, 2016 ”. Then, it is assumed that the registration information receiving unit 232 receives registration information again from the intercom base unit 10 identified by “apartment ID: 0001, building information: A, room number: 101”.

  Here, regarding the intercom master unit 10, when the authentication of the cooperation is not obtained, and the authentication code generation unit 234 receives the instruction to generate the authentication code, the authentication code generation unit 234 refers to the registration information storage unit 221 and reads “condominium ID: It is specified whether or not the current date and time has passed “30 minutes” or more from the generation date and time associated with “0001, building information: A, room number: 101”. For example, when “30 minutes” or more have elapsed, the authentication code generation unit 234 generates an authentication code different from the authentication code “0011-0002-0003-0004” generated last time, and the authentication code is displayed. It is displayed on the part 12.

  Further, the authentication code generation unit 234 generates the authentication code as described above, and also inputs the URL of the website for inputting the generated authentication code and the generated authentication code to the user's website. A two-dimensional code (QR code) including control information instructing the terminal device T is generated.

(Regarding the authentication code transmission unit 235)
The authentication code transmission unit 235 transmits the authentication code and the QR code generated by the authentication code generation unit 234 to the registration information transmission source intercom base unit 10 via the intercom server 100. For example, the authentication code transmission unit 235 transmits the authentication code and the QR code generated by the authentication code generation unit 234 to the doorphone server 100 together with the member number associated with the doorphone parent device 10 that is the registration information transmission source. Accordingly, the authentication code transmitting unit 235 indicates that the user of the registration information transmission source intercom master unit 10 is registered as a member, but the intercom procedure has not been performed, and thus the intercom authentication has not been obtained. The server 100 is notified.

(About the power information transmission unit 236)
When the authentication unit 233 authenticates the cooperation with the doorphone parent device 10, the power information transmission unit 236 transmits data regarding power consumption to the doorphone server 100 so as to be displayed on the display unit 12 of the doorphone parent device 10. . For example, the power information transmission unit 236 refers to the registration information storage unit 221 and acquires the measurement device ID associated with the authenticated doorphone parent device 10.

  Then, the power information transmission unit 236 refers to the power information storage unit 222 and acquires data related to power consumption associated with the acquired measurement device ID. Then, the power information transmission unit 236 transmits the acquired measurement device ID and data regarding power consumption to the door phone server 100. At this time, the power information transmission unit 236 also transmits the registered registration information (condominium ID, building information, room number) of the doorphone master unit 10 to the doorphone server 100.

  The power information transmission unit 236 uses the registration information of the doorphone master unit 10 with which the cooperation authentication is obtained so that the data related to the power consumption can be displayed at any time on the doorphone master unit 10 with the cooperation authentication obtained. Correspondingly, data regarding the corresponding power consumption is periodically transmitted to the doorphone server 100.

On the other hand, the cooperation between the doorphone parent device 10 and the management server 200 may be authenticated. The URL of the web page for input may be displayed on the display unit 12 together with the authentication code.

[5. Processing procedure)
Next, a procedure of authentication processing executed by the authentication processing system 1 according to the embodiment will be described with reference to FIGS. First, the procedure of the authentication process when the user has not registered as a member (referred to as “pattern A”) will be described. FIG. 10 is a sequence diagram (pattern A) showing an authentication processing procedure by the authentication processing system 1 according to the embodiment.

  First, door phone master unit 10 determines whether or not a user operation for displaying data related to power consumption has been received (step S101). Note that the user operation for displaying data related to power consumption is, for example, an operation of pressing one of the operation buttons BT1 to BT3 in FIG. When the door phone base unit 10 has not received a user operation (step S101; No), it waits until a user operation is received.

  On the other hand, when receiving the user operation (step S101; Yes), the doorphone master unit 10 transmits registration information to the doorphone server 100 (step S102). When door phone server 100 receives the registration information (step S103), door phone server 100 determines whether or not the user of door phone parent device 10 has registered as a member (step S104).

  When the door phone server 100 determines that the user has not registered the membership (step S104; No), the doorphone server 100 instructs the display unit 12 to display information for guiding the member registration, for example. Is transmitted to the intercom base unit 10 (step S105).

  When receiving the instruction (step S106), door phone master unit 10 displays information for guiding the member registration on display unit 12 (step S107).

  As described above, in FIG. 10, the authentication processing procedure in the pattern A has been described. Next, the procedure of the authentication process when the user performs member registration (referred to as “pattern B”) will be described. This process corresponds to the process (FIG. 11, step S201 and subsequent steps) subsequent to the case where the door phone server 100 determines that the user has registered as a member (step S104; Yes) in FIG. The pattern B process will be described with reference to FIG. FIG. 10 is a sequence diagram (pattern B) illustrating an authentication processing procedure by the authentication processing system 1 according to the embodiment. Note that the description of the same processing as that in FIG.

  As illustrated in FIG. 11, when the door phone server 100 determines that the user has registered as a member (step S <b> 104; Yes), the cooperation between the door phone parent device 10 and the management server 200 is authenticated. Is determined (step S201). When the intercom server 100 determines that the cooperation is not authenticated (step S201; No), the intercom server 100 requests the management server 100 to perform an authentication process (step S202). For example, door phone server 100 transmits a request including registration information received from door phone parent device 10 to management server 10.

  Upon receiving the request (step S203), the management server 200 generates an authentication code and a QR code (step S204). Then, the management server 200 transmits the authentication code and the QR code to the doorphone server 100 together with the registration information transmitted from the doorphone master unit 10 (step S205).

  When the door phone server 100 receives the registration information, the authentication code, and the QR code (step S206), the door phone server 100 transmits the authentication code and the QR code to the door phone base unit 10 so as to be displayed on the display unit 12 (step S207). When receiving the authentication code and the QR code (step S208), door phone base unit 10 displays the received authentication code and QR code on display unit 12 (step S209).

  Here, it is assumed that the user of the doorphone base unit 10 causes the management server 200 to transmit the authentication code included in the QR code by causing the terminal device T to read the QR code displayed on the display unit 12 (step S100). S210).

  When receiving the authentication code (step S211), the management server 200 performs an authentication process for authenticating the cooperation using the received authentication code (step S212). For example, when the received authentication code matches the authentication code generated in step S204, the management server 200 authenticates the cooperation. Although not shown, the management server 200 transmits information indicating the “cooperation unauthenticated” (for example, an error code) to the door phone server 100 together with the registration information when the authentication is rejected because no match is obtained.

  When the management server 200 authenticates the cooperation, the management server 200 transmits the data regarding the power consumption accumulated so far to the door phone server 100 together with the measurement device ID and the registration information (step S213).

  When intercom server 100 receives data relating to the measurement device ID, registration information, and power consumption (step S214), it generates a power graph based on the data relating to power consumption (step S215). For example, if the user performs a user operation such as pressing the operation button BT1 in step S101, the door phone server 100 generates a “power graph for each time zone”. Then, door phone server 100 transmits the generated power graph to door phone parent device 10 (step S216).

  When receiving the power graph (step S217), door phone master unit 10 displays the received power graph on display unit 12 (step S218).

  Next, a description will be given of a procedure of authentication processing when a user who completes member registration and normally performs a cooperation procedure wants to display data regarding power consumption (referred to as “pattern C”). In FIG. 11, when the door phone server 100 determines that the user has registered as a member (step S104; Yes) and further determines that the cooperation is authenticated (step S201; Yes). This corresponds to the subsequent processing. The pattern C process will be described with reference to FIG. FIG. 12 is a sequence (pattern C) showing an authentication processing procedure by the authentication processing system 1 according to the embodiment. Note that the description of the same processes (same reference numerals) as those in FIGS. 10 and 11 is omitted.

  As illustrated in FIG. 12, the door phone server 100 determines that the user is registered as a member (step S104; Yes), and further determines that the cooperation is authenticated (step S201; Yes). In this state, data related to power consumption has already been received from the management server 200 on a regular basis. Therefore, in such a case, the door phone server 100 generates a power graph using data regarding power consumption received from the management server 200 (step S301). Then, door phone server 100 transmits the generated power graph to door phone parent device 10 (step S302).

  When receiving the power graph (step S303), door phone parent device 10 displays the received power graph on display unit 12 (step S304).
