  FIG. 3 is a diagram illustrating the configuration and usage of the transceivers 2 and 4.

  Since the transceivers 2 and 4 have the same configuration, they are not distinguished and are referred to as transceivers TR. The computers 1 and 3 are called computer CMP.

  The transceiver TR includes an electrode TR1, an oscillator TR2, an electric field detector TR3, and a transmission / reception circuit TR4. In particular, the electrode TR1 of the transceiver 2 is always in contact with the human body of the user U. Further, the electrode TR1 of the transceiver 4 is always in contact with the personal belongings A. In addition, since it is possible to communicate between the transceiver TR even if the human body of the user U or the belongings A and the electrode TR1 are close to each other, the surface of the electrode TR1 may be covered with an insulator. For example, the transceiver may be of a card type so that it can communicate with it in a clothes pocket.

  The transmission / reception circuit TR4 controls the oscillator TR2 in accordance with information transmitted from the computer CMP, and the oscillator TR2 applies a voltage corresponding to the information to the electrode TR1. The transmission / reception circuit TR4 detects the information to be transmitted to the computer CMP by processing the electrical signal photoelectrically converted by the electric field detection unit TR3, and transmits this to the computer CMP.

  The electric field detector TR3 includes a light source TR31, an electro-optic crystal TR32 that modulates the polarization state of the light from the light source TR31, a polarizing plate TR33 that converts the polarization-modulated light into intensity-modulated light, and the intensity-modulated light And a photodetector TR34 for converting the signal.

(Operation of the embodiment)
FIG. 4 is a sequence diagram showing an example of the owner authentication method performed by the present system.

  For example, the computer 1 continuously transmits an owner ID (hereinafter referred to as ID) indicating the owner UA to the transmission / reception circuit TR4 of the transceiver 2 at intervals of time.

  The transmission / reception circuit TR4 oscillates the oscillator TR2 of the transceiver 2 based on the ID. The oscillator TR2 applies a voltage having a waveform corresponding to the ID to the electrode TR1 of the transceiver 2. If the human body of the user U is in contact with or close to the personal belongings A, this voltage is applied to the electrode TR1 of the transceiver 4 via the human body of the user U and the personal belongings A.

  In the electric field detector TR3 of the transceiver 4, an electric field corresponding to the waveform of the voltage is applied to the electro-optic crystal TR32, the light source TR31 enters light into the electro-optic crystal TR32, and the polarizing plate TR33 is polarized light from the electro-optic crystal TR32. The modulated light is converted into intensity modulated light, the photodetector TR34 converts the intensity modulated light into an electric signal, and the transmission / reception circuit TR4 detects the waveform of the electric signal as an ID. Then, this ID is transmitted to the computer 3 (S1).

  Initially, the computer 3 does not perform user authentication, and when the sensor 5 notifies that the possessed item A is possessed (S2), the computer 3 performs user authentication with the ID from the computer 1. become.

  The computer 3 stores the ID in advance and determines whether or not the transmitted ID is stored each time the ID is transmitted (user authentication). If the ID is not stored (authentication failure), For example, an alarm is issued (S3). Therefore, an alarm can be issued when the person who possesses the computer 1 and the transceiver 2 that transmits different IDs possesses the personal belongings A.

  Further, if the ID is not transmitted even after a certain time has elapsed from step S2, for example, an alarm is issued (S3). Therefore, an alarm can be issued when a person who does not have the computer 1 and the transceiver 2 has the personal belongings A.

  On the other hand, when the authentication is successful, that is, when the owner UA possesses the belonging A, the alarm transmission is suppressed. Therefore, it is possible to suppress alarm transmission when the owner UA possesses the possessed item A.

  After that, when the sensor 3 is notified that the possessed item A is not possessed (S4), the computer 3 does not perform the initial state, that is, user authentication. Changes.

  FIG. 5 is a sequence diagram showing another example of the owner authentication method performed by this system.

  When the computer 3 is not initially requested for an ID and is notified from the sensor 5 that the possessed item A is possessed (S11), for example, continuously at intervals. , Request an ID.

  At this time, the computer 3 applies a voltage according to the request to the electrode TR1 of the transceiver 2 in the same manner as when the computer 1 performs (S1).

  The transceiver 2 detects the request and transmits it to the computer 1 (S12) in the same manner as the transceiver 4 did (S1).

  In response to the request, the computer 1 transmits the ID to the computer 3 as in step S1 (S13).

  The computer 3 performs user authentication with the transmitted ID, and if the authentication fails, for example, issues a warning (S14). Therefore, an alarm can be issued when the person who possesses the computer 1 and the transceiver 2 that transmits different IDs possesses the personal belongings A.

  Further, if the ID is not transmitted even after a predetermined time has elapsed from step S12, for example, an alarm is issued (S13). Therefore, when a person who does not have the computer 1 and the transceiver 2 has the personal belongings A, an alarm can be issued.

  On the other hand, when the authentication is successful, that is, when the owner UA possesses the belonging A, the alarm transmission is suppressed. Therefore, it is possible to suppress alarm transmission when the owner UA possesses the possessed item A.

  Thereafter, when the computer 3 is notified from the sensor 5 that the possessed item A is not possessed (S15), the computer 3 does not request the initial state, that is, the ID. The state changes.

  If the request of FIG. 4 is not performed and only the operation of FIG. 3 is performed, the oscillator TR2 of the transceiver 4 and the electric field detector TR3 of the transceiver 2 are not necessary.
