The door 12 is locked by an electric lock 15 provided at the location of the door knob 14. The person 11 cannot open the door 12 and enter the room 13 unless the locked state of the electric lock 15 is released. The operation of locking or unlocking the electric lock 15 is controlled based on a control signal 17 (locking signal or unlocking signal) from the control device 16. As the structure of the electric lock 15, any commercially available one is used. The person 11 is, for example, a person who has a legitimate right to enter the specific room 13. This person 11 has a human body communication card holder 18 in a state where a special IC card is mounted. The IC card incorporates an RFID tag and stores ID information for identifying the person 11 in the memory of the RFID tag. Further, as will be described later, the human body communication card holder 18 includes a human body communication device and a fingerprint sensor for detecting, for example, a fingerprint that is a biometric feature. It is assumed that the person 11 is standing in front of the door 11 with the human body communication card holder 18 equipped with the IC card in his / her hand and the contact portion of the fingerprint sensor touching with his / her index finger or the like. . On the other hand, a floor electrode 20 is embedded in a place of the floor 19 outside the door 11. The floor electrode 20 functions as an antenna for human body communication. When the person 11 stands on the floor 19 on which the floor electrode 20 is installed, a communication state occurs through the body of the person 11 between the floor electrode 20 and the human body communication device in the human body communication card holder 18. In FIG. 1, reference numeral 21 denotes a state of an electric field that is generated when human body communication is performed via the body of the person 11. Data is transmitted and received between the human body communication card holder 18 and the control device 16 by human body communication based on the electric field 21 between the floor electrode 20. The control device 16 that controls the operation state of the electric lock 15 of the door 11 receives ID information (information for authenticating the FRID tag) and fingerprint information (biological information of the living body) from the human body communication card holder 18 possessed by the person 11. And the operation state of the electric lock 15 is controlled based on the received information. As described above, the RFID tag authentication system according to the present embodiment is an example applied to opening / closing control related to permission / non-permission of opening / closing of the door 11, and together with ID authentication of an IC card (RFID tag). The biometric information of the person 11 who is the user is authenticated. The authentication of the biometric information of the person 11 can be realized by attaching detection means for detecting the biometric feature of the person 11 such as a fingerprint sensor to the human body communication card holder 18.

Next, a specific external form and internal structure of the human body communication card holder 18 will be described with reference to FIGS.
As shown in FIG. 2, the external shape of the human body communication card holder 18 is the shape of a card holder that is thin and flat as a whole, and has an IC card 31 on one short side in a rectangular shape as viewed from the front. The slit opening 32 is formed so that it can be inserted and removed freely. A recess 32 a is formed in a part of the wall portion of the slit port 32. Inside the human body communication card holder 18, there is provided a housing portion 33 for housing the IC card 31 inserted from the slit port 32. As shown in FIG. 3, the front shape of the human body communication card holder 18 is substantially rectangular. On the front part of the human body communication card holder 18, an area part 34 in which an IC card antenna is incorporated is provided. The IC card antenna is an antenna for transmitting and receiving data to and from the RFID tag in the IC card 31 accommodated in the human body communication card holder 18. As shown in FIG. 4, a battery housing portion 35 and a fingerprint sensor 36 are provided on the back surface of the human body communication card holder 18. The fingerprint sensor 36 is, for example, a swipe type fingerprint detection means, and detects the fingerprint of the fingertip when the fingerprint reading portion of the fingertip is brought into contact with the sensor reading portion exposed on the back surface of the human body communication card holder 18 and read. . In FIG. 4, the battery accommodating part 35 is shown in the state closed by the lid | cover. Although not clearly shown in FIGS. 2 to 4, human body communication electrodes are further provided in a built-in state on both sides of the front and back portions of the human body communication card holder 18.

  With reference to FIG. 5, an internal configuration of the human body communication card holder 18 according to the present embodiment and a configuration related to human body communication between the human body communication card holder 18 and the RFID tag authentication system will be described. In the case of this embodiment, the authentication of the IC card 31, that is, the RFID tag, and the fingerprint authentication are executed on the control device 16 side.

  Inside the human body communication card holder 18, an IC card antenna 41, an IC card reader / writer 42, and a fingerprint sensor 36 are provided as a reception input unit. The fingerprint reading portion of the fingerprint sensor 36 is exposed on the back side of the human body communication card holder 18. When the IC card 31 is accommodated in the human body communication card holder 18, wireless communication is performed between the IC card 31 and the IC card antenna 41, and the ID information stored in the memory of the IC card 31 is the IC card reader. Read by writer 42 When the person 11 who is a user touches the fingerprint portion of the finger 11 </ b> A with the fingerprint reading unit of the fingerprint sensor 36, the fingerprint sensor 36 detects the fingerprint and acquires fingerprint feature information.

  Reference numeral 43 denotes an arithmetic control processing unit, which includes a memory 44. As described above, the ID information read by the IC card reader / writer 42 and the characteristic information of the fingerprint detected by the fingerprint sensor 36 are given to the arithmetic control processing unit 43. The arithmetic control processing unit 43 transfers the ID information of the given IC card 31 and the characteristic information of the fingerprint of the finger 11A to the human body communication conversion circuit 45. The human body communication conversion circuit 45 converts the ID information of the IC card 31 and the characteristic information of the fingerprint of the finger 11 </ b> A into human body communication data and sends it to the human body communication electrode 46. The human body communication data is transmitted between the human body communication electrode 46 and the floor electrode 20 via the human body of the person 11 and the electric field 21. Communication is also performed between the human body communication card holder 18 and the human body of the person 11 by the electric field 47.

The information is collated with the corresponding registered ID information and fingerprint feature information stored in the built-in memory, and it is determined whether the ID information and the fingerprint feature information match the corresponding information, respectively. When it is determined as a match in the collation determination result by the control device 16, a control signal 17 for releasing the locked state is generated and sent to the electric lock 15 to release the locked state of the electric lock. Thereby, the person 11 can open the door 12 and enter the room 13. When the door 11 is closed, the electric lock 15 is automatically locked again. When it is determined that there is a mismatch in the collation determination result by the control device 16, a control signal for releasing the locked state is not generated, and the locked state of the electric lock 15 is maintained. As a result, the door 12 does not open and the person 11 cannot enter the room 13.
