  The human body communication device 110 communicates with the human body device 200. A human body carries the human body device 200. As another example, the human body device 200 may be incorporated in a uniform of a wearer. The human body device 200 employs an electrostatic coupling method, and may be in direct contact with or close to the human body. The person who carries the human body device 200 is, for example, a carrier such as an employee of a transport source company and a transport destination company, in addition to a transporter such as a security-related person who transports the transport case 100. When there are a plurality of persons carrying the transport case 100, each person wears the human body device 200.

  The wireless device is installed in the loading platform of the security transport vehicle 300 in which the transport case 100 is accommodated or in the building 400 in which the transport case 100 is carried out and carried in. For example, as shown in FIG. 2, the loading platform 302 of the security transport vehicle 300 is a safe room, and the first wireless device 310 is installed inside the safe room. The loading platform 302 of the security transport vehicle 300 is provided with a loading platform, and the transport case 100 is carried into and out of a safe room as a loading platform via the loading platform door 304.

  In addition, as shown in FIG. 3, a wireless device is also installed in a building 400 where the transport case 100 is carried out and carried in. The interior of the building is divided into, for example, two sections, a delivery section 410 and a handling section 430, and a second radio 420 and a third radio 440 are installed in the delivery section 410 and the handling section 430, respectively.

  The handling section 430 is a section in which, for example, employees of the transport source and the transport destination of the transport case 100 handle the transport case 100 and do not face the outside. The delivery section 410 is a place where the transport case 100 is unloaded and transported, and is a section in which the transport case 100 is delivered between a transport source employee, a transport destination employee, and a transporter such as a security company employee. is there. The delivery section 410 is provided with a door 412 serving as a boundary with the outside.

  FIG. 4 is a block diagram illustrating a functional configuration of the first radio device 310. The first wireless device 310 includes a door detection unit 311 and a transmission unit 312. The door detection unit 311 detects opening / closing of the loading platform 302. The transmission unit 312 transmits a signal A when the door detection unit 311 detects that the loading platform door 304 is closed, and stops transmitting the signal A when it detects that the loading platform door 304 is opened. To do.

  The functional configuration of the second radio 420 is the same as the functional configuration of the first radio 310 described with reference to FIG. That is, the second wireless device 420 includes a door detection unit and a transmission unit. The door detection unit of the second wireless device 420 detects opening / closing of the door 412. The transmission unit of the second wireless device 420 transmits a signal A when detecting that the door 412 is closed, and stops transmitting the signal A when detecting that the door 412 is opened. The third radio 440 includes only a transmission unit. The transmission unit of the third wireless device 440 always transmits the signal A.

  FIG. 5 is a block diagram illustrating a functional configuration of the human body communication device 110. The human body communication device 110 includes a wireless communication unit 112, a human body communication unit 113, a message storage unit 116, an encryption key storage unit 117, a human body detection unit 118, an authentication unit 119, a warning operation unit 120, and an operation control. Part 121.

  The wireless communication unit 112 receives the signal A from each of the first wireless device 310, the second wireless device 420, and the third wireless device 440. The human body communication unit 113 includes a transmission electrode 114 and a reception electrode 115, and transmits / receives various information to / from the human body device 200. The message storage unit 116 stores a message M used for authentication of the human body device 200. The encryption key storage unit 117 stores an encryption key K used for authentication of the human body device 200.

  The human body detection unit 118 transmits / receives a signal to / from the human body device 200 via the human body communication unit 113 and detects the human body based on the received signal. Specifically, the signal B is transmitted from the transmission electrode 114. The signal B is received by the human body device 200, passes through the human body, and is transmitted again to the human body communication apparatus 110 by the human body device 200. When the reception electrode 115 receives the signal B after the reception electrode 115 has passed through the human body 200 from the human body device 200, the human body detection unit 118 transmits the phase of the signal B received from the human body device 200 and the transmission electrode 114 to the human body device 200. The human body is detected based on the phase difference of the phase of the signal B. Specifically, when the phase of the signal B received from the human body device 200 is advanced as compared with the phase of the signal B transmitted to the human body device 200, the carrier holds the handle portion 102 of the transport case 100. That is, it is determined that a human body has been detected. As described above, the human body detection unit 118 detects the human body by utilizing the fact that a phase difference occurs between signals before and after passing through the human body due to the capacity and resistance of the human body.

  The authentication unit 119 authenticates the wearer wearing the human body device 200 based on the information received via the human body communication unit 113. Specifically, when the transmission electrode 114 of the human body communication unit 113 transmits the signal B to the human body device 200, the message M is transmitted as a question together with the signal B. The human body device 200 concatenates the message M with its own encryption key K as an answer to the question, creates a hash value of the concatenated value, and transmits the hash value as a reply to the human body communication device 110. When the reception electrode 115 receives this answer, the authentication unit 119 concatenates the message M stored in the encryption key storage unit 117 and the encryption key K stored in the encryption key storage unit 117, and hashes the concatenated value. Create a value. Then, the created hash value is compared with the hash value as an answer received by the receiving electrode 115 from the human body device 200. If both hash values match, that is, if the answer is correct, it is determined that the authentication is successful. If the two hash values do not match, that is, if the answer is incorrect, it is determined that the authentication has failed.

  The alert operation unit 120 performs an alert operation when the authentication unit 119 fails in authentication. As the warning operation, for example, an alarm is transmitted to the security center. Moreover, as another example, a banknote is made unusable by spraying ink on the transport case 100. As another example, a loud buzzer is sounded. Note that the security operation is not limited to the embodiment, as long as the security operation is to notify the surroundings or the security center by some means.

  The operation control unit 121 monitors whether or not the signal A is received from the wireless communication unit 112, and based on whether or not the signal A is received, the human body communication unit 113, the human body detection unit 118, the authentication unit 119, and the warning operation unit The human body communication operation which is the operation by 120 is controlled.

  The human body communication unit 113 of the human body communication device 110 is provided in the handle unit 102 of the transport case 100 as shown in FIG. Thereby, when a portable person grasps the handle part 102 of the conveyance case 100, human body communication with a portable person's human body device 200 can be performed by human body communication.

  FIG. 7 is a block diagram showing a functional configuration of the human body device 200. The human body device 200 includes a reception electrode 201, a transmission electrode 202, an encryption key storage unit 203, and an answer generation unit 204. The reception electrode 201 and the transmission electrode 202 transmit / receive various information to / from the human body communication device 110. The encryption key storage unit 203 stores an encryption key K used for authentication of the human body device 200. Note that the encryption key stored in the encryption key storage unit 203 and the encryption key stored in the encryption key storage unit 117 of the human body communication device 110 have the same value. The answer generation unit 204 generates an answer based on the message M received via the reception electrode 201 and the encryption key K stored in the encryption key storage unit 203. Specifically, as described above, after concatenating the message M and the encryption key K stored in the encryption key storage unit 203, a hash value of the concatenated value is created. Then, the hash value is transmitted as an answer to the human body communication device 110 via the transmission electrode 202.

  FIG. 8 is a flowchart showing the conveyance security process by the human body communication device 110. When the signal A is not received from any of the first radio device 310, the second radio device 420, and the third radio device 440 (step S100, No), the operation control unit 121 performs the human body communication operation in the human body communication device 110. Is permitted (step S102), and the process proceeds to step S106 to perform human body communication processing.

  On the other hand, when the signal A is received from any one of the first radio 310, the second radio 420, and the third radio 440 (step S100, Yes), the operation control unit 121 performs the human body communication operation. Is prohibited (step S104). In this case, the process returns to step S100 again, and the operation control unit 121 continues monitoring whether or not the signal A is received.

  When the human body communication operation is permitted (step S102), the transmission electrode 114 of the human body communication unit 113 transmits the signal B and the message M stored in the message storage unit 116 to the human body device 200 (step S102). S106). Next, the human body detection unit 118 detects the human body based on the phase difference between the signal B received from the human body device 200 and the signal B transmitted from the transmission electrode 114. If the human body is detected by the human body detection unit 118 (step S108, Yes), the authentication unit 119 then authenticates the carrier. In other words, when the transmission electrode 114 receives a response within a predetermined time after the reception electrode 115 transmits the message M as a question (step S110, Yes), the authentication unit 119 receives the response received by the reception electrode 115. And the hash value created based on the message M stored in the message storage unit 116 and the encryption key K stored in the encryption key storage unit 117.

  When the hash value as the answer received by the reception electrode 115 matches the hash value created by the authentication unit 119, that is, when the authentication of the carrier is successful (step S112, Yes), the warning operation is not performed. Return to step S100.

  On the other hand, if no human body is detected in step S108 (step S108, No), if no response is received from the human body device 200 within a predetermined time in step S110 (step S110, No), authentication fails in step S112. In the case (step S112, No), the warning operation unit 120 performs a warning operation (step S114).

  As a conveyance route of the conveyance case 100, the following route is assumed. That is, first, in the handling section 430 of the transport source, valuables are stored in the transport case 100 by the handler. Next, the transport case 100 is transported to the delivery section 410 where it is handed over from the handler to the transporter. The transport case 100 carried by the transporter passes through the door 412 of the delivery section 410 and is carried out of the building 400. Then, it is loaded on the loading platform 302 through the loading platform door 304 of the security transport vehicle 300.

  The transport case 100 is transported by the security transport vehicle 300, carried by the transporter, and transported to the delivery section 410 in the transport destination building 400. In the delivery section 410, it is delivered from the carrier to the handler. Thereafter, it is carried to the handling section 430 by the handler.

  While being transported along the transport path described above, the human body communication device 110 installed in the transport case 100 performs the transport security process described with reference to FIG.

  The handling section 430 is a safe section that does not directly communicate with the outside. Therefore, the signal A is always transmitted from the third radio 440 installed in the handling section 430. Thereby, in the handling section 430, the transport case 100 always receives the signal A and prohibits the human body communication operation in the transport security process (step S100, Yes, step S104). As described above, in the handling section 430 that is a safe section, by prohibiting the human body communication operation, it is possible to reduce the battery consumption of the human body communication apparatus 110. Further, by prohibiting the human body communication operation in the handling section 430, even in the handling section 430, even a person carrying the transport case 100 does not need to wear the human body device 200, and the convenience of the human body communication apparatus 110 is improved. Can be improved.

  The delivery section 410 is provided with a door 412 connected to the outside. When the door 412 is open, an unauthorized intruder from the outside may enter. Therefore, only when the door 412 is closed, the signal A is transmitted to the second radio 420 installed in the delivery section 410. Accordingly, when the door 412 is closed in the delivery section 410, the transport case 100 receives the signal A and prohibits the human body communication operation in the transport security process (step S100, Yes, step S104). In this manner, when the door 412 is closed and the safety of the transport case 100 is ensured, the battery consumption of the human body communication device 110 can be reduced by prohibiting the human body communication operation. Furthermore, when the door 412 is closed, the handling case 100 can be carried by a handler who does not wear the human body device 200 in the delivery section 410, and the convenience of the human body communication device 110 can be improved.

  On the other hand, when the door 412 is open, the transport case 100 does not receive the signal A and permits the human body communication operation in the transport security process (step S100, No, step S102). Therefore, when an intruder from the outside appears, a warning operation can be performed, and the safety of the transport case 100 can be ensured.

  In this way, even in the same section, when the safety state changes due to opening and closing of the door, etc., by setting whether or not to perform the human body communication operation according to the state, the human body communication operation is performed only when necessary. Therefore, the battery consumption of the human body communication device 110 can be effectively reduced while ensuring the safety of the transport case 100.

  When the transport case 100 is routed from the building 400 to the guarded transport vehicle 300 by the transporter, the human body communication device 110 does not receive the signal A from any wireless device. Therefore, the human body communication device 110 permits the human body communication operation (Step S100, No, Step S102). Thereby, the safety of the transport case 100 can be ensured.

  The loading platform 302 of the security transport vehicle 300 is basically a safe area, but a loading platform door 304 connected to the outside is provided, and when the loading platform door 304 is open, an intruder is placed inside the loading platform 302. There is a possibility of intrusion. Therefore, the signal A is transmitted to the first radio 310 only when the cargo door 304 is closed. Thereby, when the loading platform door 304 is closed in the loading platform 302, the conveyance case 100 receives the signal A in the conveyance security processing, and prohibits the human body communication operation (step S100, Yes, step S104). As described above, when the cargo door 304 is closed and safety is ensured, the battery consumption of the human body communication device 110 can be reduced by prohibiting the human body communication operation.

  Further, for example, when the carrying of the transport case is detected by an acceleration sensor or the like, and the human body is detected, the security transport vehicle 300 is moving in a configuration in which authentication of the carrier of the transport case 100 is performed. Since the human body communication operation is stopped during this time, it is possible to prevent the occurrence of false alarms.

  On the other hand, when the loading platform door 304 is open, the transport case 100 does not receive the signal A in the transport security process and permits the human body communication operation (step S100, No, step S102). Therefore, when an intruder appears, a warning operation can be performed, and the safety of the transport case 100 can be ensured.

  As described above, in the security transport vehicle 300 as well, it is possible to perform the human body communication operation only when necessary by setting whether or not the human body communication operation is performed in accordance with the opening / closing of the loading platform door 304. The battery consumption of the human body communication device 110 can be effectively reduced while ensuring 100 safety.

  Note that the installation position of the wireless device and the signal generation timing are not limited to the present embodiment, and may be appropriately installed according to the conveyance route and handling location of the conveyance case 100 and the timing may be controlled appropriately. Specifically, although the carrying case 100 is not carried by the carrier, the wireless device is installed in a safe place where there is no possibility of burglary or the like or is extremely low. Furthermore, if it is safe only when a predetermined condition is met, for example, it is safe only when the door is closed, the signal transmission of the radio is controlled so that the signal A is transmitted only at a safe timing. do it.

  As a first modification, as shown in FIG. 9, the human body communication unit 113 of the human body communication device 110 may be provided on the side surface 104 of the transport case 100. Furthermore, the human body communication unit 113 may include a plurality of transmission electrodes 114a to 114c and a plurality of reception electrodes 115a and 115b. In this case, the plurality of transmission electrodes 114 a to 114 c and the plurality of reception electrodes 115 a and 115 b are alternately arranged on the side surface 104 of the transport case 100.
