  FIG. 1 is a block diagram illustrating the configuration of the information processing apparatus according to this embodiment. The information processing apparatus includes a transmission unit 120 and a mobile terminal 200. The transmitter 120 is installed inside the building 100 and emits electromagnetic waves or light having a predetermined wavelength. The mobile terminal 200 is used inside a building, and includes a wireless communication unit 210, an authentication data storage unit 220, an authentication data reading unit 230, a receiving unit 240, and a control unit 250. The wireless communication unit 210 performs wireless communication with the communication line 420. The authentication data storage unit 220 stores authentication data for allowing the authentication device 400 connected to the communication line 420 to authenticate. The authentication data reading unit 230 reads the authentication data from the authentication data storage unit 220 and causes the wireless communication unit 210 to transmit the authentication data. The receiving unit 240 receives an electromagnetic wave or light having a predetermined wavelength transmitted from the transmitting unit 120. The control unit 250 enables both the wireless communication unit and the authentication data reading unit when the receiving unit 240 receives an electromagnetic wave or light having a predetermined wavelength.

  The light or electromagnetic wave transmitted by the transmitter 120 is, for example, infrared rays, but is not limited to infrared rays as long as it is light or electromagnetic waves having a wavelength that does not drop the outer wall of the building 100.

  The wireless communication unit 210 performs wireless communication with the communication line 420 via the in-building wireless communication unit 110 installed inside the building 100. The control unit 250 of the mobile terminal 200 further functions as an authentication result receiving unit. That is, after the wireless communication unit 210 transmits authentication data, the control unit 250 receives authenticated information indicating that the authentication device 400 has authenticated the mobile terminal 200 via the wireless communication unit 210.

  The mobile terminal 200 further includes an input unit 260 for inputting information. After the control unit 250 receives the authenticated information, the wireless communication unit 210 transmits the information input to the input unit 260 to an external device (for example, the authentication device 400) connected to the communication line. The input unit 260 includes, for example, a key (not shown) for performing key input, a code reading unit 262, and a wireless tag communication unit 264. The code reading unit 262 reads a barcode or a two-dimensional code attached to a stored item in the building 100 and causes the wireless communication unit 210 to transmit it. The wireless tag communication unit 264 acquires information from the wireless tag attached to the stored items in the building 100 and causes the wireless communication unit 210 to transmit the information.

  In FIG. 1, the configuration of parts not related to the essence of the present invention is omitted. Each component of the mobile terminal 200 illustrated in FIG. 1 is not a hardware unit configuration but a functional unit block. Each component of the portable terminal 200 includes a CPU, a memory, a program that realizes the components of this figure loaded in the memory, a storage unit such as a hard disk that stores the program, and a network connection. It is realized by any combination of hardware and software, with a focus on the interface. It will be understood by those skilled in the art that there are various modifications to the implementation method and apparatus.

  FIG. 2 is a diagram for explaining an arrangement example of the in-building wireless communication unit 110 and the transmitting unit 120 in the building 100. In the example shown in the figure, a plurality of in-building wireless communication units 110 and a plurality of transmitting units 120 are installed inside the building 100.

  The plurality of in-building wireless communication units 110 are arranged in a matrix at regular intervals on the ceiling of the building 100, for example. The arrangement interval of the in-building wireless communication unit 110 is determined based on the communicable distance between the mobile terminal 200 and the in-building wireless communication unit 110 so that the mobile terminal 200 can perform wireless communication from any location in the building 100.

  The plurality of transmitters 120 are arranged at regular intervals, for example, on the wall or ceiling of the building 100. The arrangement interval of the in-building wireless communication unit 110 is determined based on the receivable distance of the mobile terminal 200 so that the mobile terminal 200 can receive light or electromagnetic waves from any location in the building 100. Note that the above-described receivable distance is preferably set so that a receivable area corresponding to one transmitting unit 120 is limited to a specific place in the building 100.

  Moreover, the transmission part 120 is transmitting the positional information which shows the position of the transmission part 120 using the electromagnetic wave or light of a predetermined wavelength. And the receiving part 240 of the portable terminal 200 shown in FIG. The wireless communication unit 210 of the mobile terminal 200 transmits the position information received by the reception unit 240 to the authentication device 400 via the in-building wireless communication unit 110.

  The building 100 is provided with a security gate 130. The security gate 130 functions so that only those who have authority to enter the building 100 can enter the building 100.

  FIG. 3 is a block diagram illustrating functions of the security gate 130. The security gate 130 includes an authentication data receiving unit 132, a person authentication unit 134, an entrance control unit 136, and an entrance restriction unit 138. The authentication data receiving unit 132 receives authentication data from a person who wants to enter the building 100. The authentication data is transmitted using, for example, a security card. Based on the authentication data received by the authentication data receiving unit 132, the person authentication unit 134 determines whether or not the person who intends to enter the building 100 has the authority to enter the building 100. Then, when the person authentication unit 134 authenticates that the person has the authority described above, the entrance control unit 136 controls the entrance restriction unit 138 so that the person can enter the building 100.

  FIG. 4 is a flowchart for explaining operations performed by the mobile terminal 200. The receiving unit 240 indicates that the position information received from the transmitting unit 120 is received by the light or electromagnetic wave while receiving the light or electromagnetic wave having a predetermined wavelength transmitted by the transmitting unit 120. The received signal is output to the control unit 250.

  First, the operator of the mobile terminal 200 inputs transmission instruction information indicating that the authentication data is transmitted to the authentication device 400 to the input unit 260 (step S10). When the transmission instruction information is input to the input unit 260, the control unit 250 confirms whether or not the position information of the transmission unit 120 is received from the reception unit 240 (step S20). When the positional information of the transmission part 120 is not received (step S20: No), the portable terminal 200 complete | finishes a process. When the position information of the transmission unit 120 is received (step S20: Yes), the control unit 250 enables both the wireless communication unit 210 and the authentication data reading unit 230 to operate. The authentication data reading unit 230 reads authentication data from the authentication data storage unit 220. Then, the wireless communication unit 210 transmits the authentication data to the authentication device 400 via the in-building wireless communication unit 110 and the communication line 420 (step S30). At this time, the wireless communication unit 210 may transmit the position information received from the transmission unit 120. Further, the control unit 250 holds the position information of the transmission unit 120.

  The authentication device 400 determines whether to authenticate the mobile terminal 200 based on the received authentication data. Then, the authentication device 400 transmits information indicating the authentication result to the mobile terminal 200 via the communication line 420 and the in-building wireless communication unit 110. When the authentication apparatus 400 receives the position information together with the authentication data from the portable terminal 200, the authentication apparatus 400 may further transmit the authenticated information to the portable terminal 200 on the condition that the position information is correct position information.

  When the received information indicates that the received information is not authenticated, the mobile terminal 200 ends the process. If the received information is authenticated information (step S40), the portable terminal 200 requests necessary data from the authentication device 400 according to the information input by the operator to the input unit 260 (step S50). Then, when receiving the requested data from the authentication device 400, the portable terminal 200 displays the received data and allows the operator to recognize it (step S60). In addition, the code reading unit 262 of the mobile terminal 200 reads a bar code or a two-dimensional code attached to a stored item in the building 100 and outputs it to the control unit 250. Further, the wireless tag communication unit 264 acquires information from the wireless tag attached to the stored items in the building 100 and outputs the information to the control unit 250. The control unit 250 causes the wireless communication unit 210 to transmit the received barcode or two-dimensional code or information received from the wireless tag (step S70 and step S80).

  In addition, after the process of step S10-step S40 is performed, when the operator of the portable terminal 200 moves, the portable terminal 200 may come to receive position information from another transmission part 120. FIG. In this case, the control unit 250 of the mobile terminal 200 updates the held position information to the position information received from another transmitting unit 120.

  In the processing shown in step S70 and step S80, the control unit 250 wirelessly combines the information received from the barcode, the two-dimensional code, or the wireless tag with the position information of the transmission unit 120 held by the control unit 250. You may make it transmit to the communication part 210. FIG. Then, the authentication device 400 processes the information received from the barcode, the two-dimensional code, or the wireless tag.

  Next, the operation and effect of this embodiment will be described. According to the present embodiment, the wireless communication unit 210 and the authentication data reading unit 230 of the mobile terminal 200 operate when the receiving unit 240 receives an electromagnetic wave or light having a predetermined wavelength. Therefore, even if a person who has illegally acquired the mobile terminal 200 tries to connect to the authentication device 400 by operating the mobile terminal 200 from outside the building 100, the mobile terminal 200 cannot transmit authentication data to the authentication device 400. . Accordingly, unauthorized connection to the authentication device 400 can be suppressed.

  Further, when the transmitting unit 120 transmits position information indicating the position of the transmitting unit 120 via an electromagnetic wave or light having a predetermined wavelength, and the receiving unit 240 of the mobile terminal 200 receives the position information, the mobile terminal 200 When the authentication device 400 is authenticated, the location information of the transmitting unit 120 with which the mobile terminal 200 is communicating can be transmitted to the authentication device 400. In this case, the authentication device 400 transmits the authenticated information to the mobile terminal 200 on the condition that the position information is correct position information. Therefore, unauthorized connection to the authentication device 400 can be further suppressed.

  In addition, the control unit 250 of the mobile terminal 200 stores the latest position information received by the receiving unit 240 from the transmitting unit 120. Then, the control unit 250 combines the stored position information with the barcode or two-dimensional code read by the input unit 260 or the information received from the wireless tag even if no special input from the operator is performed. It transmits to the authentication device 400. For this reason, when the barcode or two-dimensional code read by the input unit 260 or the information received from the wireless tag is information for specifying the stored item, the authentication device 400 can store any storage in any location in the building 100. It is possible to recognize whether an object is stored.
