  The subunit | mobile_unit 110 is affixed on the portable recording medium 101, for example.

  When the slave unit 110 attached to the portable storage medium 101 is peeled off from the portable storage medium 101, the slave unit 110 itself is damaged, and the portable storage medium 101 is also damaged.

  When the portable storage medium 101 is a recording device such as the USB memory or the portable hard disk, for example, the slave unit 110 is affixed on the wiring of a built-in circuit board. Since the wiring of the circuit board is deposited on the circuit board, if the slave unit 110 is peeled off, the wiring is also peeled off and data cannot be read.

  The slave unit 110 is attached to the recording surface when the portable storage medium 101 is, for example, a CD or a DVD. Since the recording surface of a CD, DVD or the like is on a film, if the slave unit 110 attached to the recording surface is peeled off, the recording surface is also peeled off and the recorded data cannot be read.

  Next, the configuration of base unit 120 will be described.

  FIG. 3 shows a block configuration diagram of base unit 120.

  The master unit 120 is a device corresponding to the master unit of the anti-theft device, and is given, for example, for each personal computer 140 or for each staff member. The master unit 120 is configured to perform wireless communication with the slave unit 110 and the monitoring device 130 and to be connected to a USB port of the personal computer 140 or the like. The base unit 120 includes, for example, a communication unit 121, a processing unit 122, a base unit storage unit 123, an interface 124, a battery 125, a human body detection unit 126, an output unit 127, a USB port 128, and the like.

  The communication unit 121 includes devices for performing wireless communication with the slave unit 110 and the monitoring device 130, acquires a slave unit identifier from the slave unit 110, and notifies the monitoring unit 130 of the master unit identifier and the like. The processing unit 122 reads out the master unit identifier in response to a request from the monitoring device 130, transmits the master unit identifier to the monitoring device 130, and at the same time, receives a data transfer request from the personal computer 140 to the portable recording medium 101. It corresponds to the machine identifier, is registered in the monitoring device 130, processing for permitting data transfer to the personal computer 140, notification to the monitoring device 130 based on the detection result of the human body detection unit 126, and output of an alarm from the output unit 127 Various processing such as processing is performed.

  The parent device storage unit 123 is a memory and stores a parent identifier. The interface 124 communicates with the personal computer 140 through a USB interface. The battery 125 is composed of a secondary battery or the like, and is charged with a DC voltage of 5 V supplied from the personal computer 140 via the USB port 128, and the communication unit 121, the processing unit 122, and the parent device storage unit of the parent device 120 123, the interface 124, the human body detection unit 126, the output unit 127, and the like.

  The human body detection unit 126 includes a device that detects that the parent device 120 is close to the human body using a technique called human body communication using the human body as a communication path. The human body detection unit 126 has a transmission electrode and a reception electrode on the human body side, applies a specific signal to the transmission electrode, and detects the reception electrode so that the master unit 120 is provided close to the human body. Can be detected. For example, when the base unit 120 is provided close to air or an insulator, a specific signal cannot be detected from the transmission electrode by the reception electrode, and it can be detected that the base unit 120 is not close to the human body. When base unit 120 is provided close to the conductor, a specific signal from the transmission electrode appears at the reception electrode with almost no attenuation or delay, so that it can be detected that the base unit 120 is not close to the human body.

  Furthermore, when the main unit 120 is provided close to the human body, the human body has a resistance and a capacitance component, so that a specific signal from the transmission electrode attenuates according to the resistance component of the human body and is converted into a capacitance component. Accordingly, it appears on the receiving electrode with a delay, so that it is possible to detect the proximity to the human body.

  Thereby, it is possible to detect whether or not the parent device 120 is carried by the human body by the human body detection unit 126.

  For example, the base unit 120 is attached with a belt or the like, and is configured so that it can be attached to any part of the body (the waist, the wrist, etc.).

  The output unit 127 includes a speaker, a flash, and the like. The output unit 127 outputs a buzzer or a message in response to an instruction from the processing unit 122, or the flash blinks. The master unit 120 outputs an alarm from the output unit 127 when a state in which a human body is not detected by the human body detection unit 126 continues for a certain time or longer after pairing with the slave unit 110 is performed. Has been. As a result, when the portable storage medium 101 is transported, the master unit 120 can be prevented from being lost or misplaced.

  The USB port 128 is composed of, for example, a USB socket connector or a USB plug connector, and is connected to the USB port of the personal computer 140 via a USB cable.

  Next, the configuration of the monitoring device 130 will be described.

  FIG. 4 is a block diagram of the monitoring device 130.

  For example, the monitoring device 130 is installed on the indoor ceiling near the entrance and exits, reads the identifier of the slave unit 110 and the identifier of the master unit 120, and generates an alarm sound, an alarm message, and the like according to the read result. It is possible to report to a predetermined report destination.

  The monitoring device 130 includes a communication unit 131, a processing unit 132, a monitoring device storage unit 133, an interface 134, an output unit 135, and the like. The communication unit 131 is a device for performing wireless communication with the child device 110 and the parent device 120.

  The processing unit 132 stores, in the monitoring device storage unit 133, the slave unit identifier and the master unit identifier pair received from the master unit 120 through the communication unit 131 or the interface 134, and from the slave unit 110 through the communication unit 131. The status of the slave unit 110 and the master unit 120 is detected based on the received slave unit identifier and the master unit identifier received from the master unit 120 through the communication unit 131, and an alarm is output from the output unit 135 when there is an abnormality. The alarm is notified to the reporting terminal device 150 through the network 160.

  The monitoring device storage unit 133 includes a memory or the like, and stores a pair of a slave unit identifier and a master unit identifier received from the master unit 120 via the communication unit 131 or the interface 134.

  The interface 134 is a device for communicating with the personal computer 140 and the report destination terminal device 150 via the network 160.

  The output unit 135 includes a speaker, a flash, and the like. The output unit 135 outputs a buzzer and a message in response to an instruction from the processing unit 132, and the flash blinks.

  Note that the network 160 includes a wired or wireless secure communication line such as a wireless LAN or a wired LAN, and includes, for example, a SSL LAN, a VPN communication, a wireless LAN based on the WEP method, and the like.

  Next, an operation when data is moved to the portable storage medium 101 by the personal computer 140 will be described.

  FIG. 5 is a diagram for explaining the operation of one embodiment of the present invention.

  At this time, it is assumed that the slave unit 110 and the master unit 120 are connected to the USB port of the personal computer 140, and the slave unit 110 and the master unit 120 are not paired.

  When the personal computer 140 is instructed to transfer data to the portable storage medium 101 in step S1-1, the personal computer 140 transmits a data transfer notification to the parent device 120 in step S1-2.

  When receiving the data transfer notification from personal computer 140 in step S2-1, master device 120 requests the slave device identifier from slave device 110 in step S2-2.

  When receiving the request for the slave unit identifier from the master unit 120 in step S 3-1, the slave unit 110 reads the slave unit identifier from the slave unit storage unit 113 and transmits it to the master unit 120 in step S 3-2.

  When receiving the slave unit identifier from slave unit 110 in step S2-3, master unit 120 stores the received slave unit identifier in base unit storage unit 123, and from base unit storage unit 123 in step S2-4. Is read. Base unit 120 creates a pair of the base unit identifier received in step S2-5 and the base unit identifier read from base unit storage unit 123, and transmits the pair to monitoring device 130 in step S2-6.

  When the monitoring device 130 receives the pair of the slave unit identifier and the master unit identifier from the master unit 120 in step S4-1, the monitoring device 130 determines the pair of the slave unit identifier and the master unit identifier received from the master unit 120 in step S4-2. The data is stored in the monitoring device storage unit 133. When monitoring device 130 stores the pair of the child device identifier and the parent device identifier received from parent device 120 in monitoring device storage unit 133, monitoring device 130 transmits a pair registration completion notification to parent device 120 in step S4-3.

  When receiving the pair registration completion notification from monitoring device 130 in step S2-7, master device 120 transmits a data transfer permission notification to personal computer 140 in step S2-8.

  When the personal computer 140 receives the data transfer permission notification from the parent device 120 in step S1-3, it transfers the data to the portable storage medium 101 in step S1-4. When the transfer of data to the portable storage medium 101 is completed in step S1-5, the personal computer 140 transmits a data transfer completion notification to the parent device 120 in step 1-6.

  When base unit 120 receives a data transfer completion notification from personal computer 140 in step S2-9, whether or not a human body is detected by human body detection unit 126 within a predetermined time in steps S2-10, S2-11, and S2-12. Determine. Note that step S2-10 is a step for starting time measurement, step S2-11 is a step for determining a detection result from the human body detection unit 126, and step S2-12 is a predetermined step after the time measurement is started. It is a step of determining whether or not time has elapsed.

  If the human body is not detected by the human body detection unit 126 within a predetermined time in steps S2-10, S2-11, and S2-12, the carrier of the portable storage medium 101 sends the parent device 110 to the personal computer 140. At step S2-13, an alarm is output from the output unit 127. Accordingly, the carrier can notice that the parent device 120 is not worn on the body.

  In addition, the main | base station 120 may notify a warning to the report destination terminal device 150 through the personal computer 140, the monitoring device 130, or the like. Accordingly, it is possible to notify the carrier that the parent device 110 is not worn on the body from the report destination.

  If the human body is detected by human body detection unit 126 within a predetermined time in steps S2-10, S2-11, and S2-12, base unit 120 determines that base unit 120 is worn by the carrier. In step S2-14, the detection result of the human body detection unit 126 is monitored.

  If base unit 120 detects the human body as a result of detection by human body detection unit 126 in step S2-14, base unit 120 determines that it is attached to the body of the carrier. If the detection result of human body detection unit 126 in step S2-14 cannot detect a human body, base unit 120 determines that base unit 120 has been dropped or forgotten, and output unit 127 in step S2-13. Outputs an alarm.

  The alarm may be notified to the report destination terminal device 150 through the personal computer 140, the monitoring device 130, or the like.

  The master unit 120 requests the slave unit 120 for a slave unit identifier in step S2-15. When receiving the request for the slave unit identifier in step S 3-1, the slave unit 110 reads the slave unit identifier from the slave unit storage unit 113 and transmits it to the master unit 120 in step S 3-2.

When receiving the slave unit identifier in step S2-16, master unit 120 determines the validity of the slave unit identifier received in step S2-17. That is, it is determined whether or not the received slave unit identifier matches the slave unit identifier stored in the base unit storage unit 123.
If the slave unit identifier received in step S2-17 matches the slave unit identifier stored in base unit storage unit 123, master unit 120 has received the valid slave unit identifier and is paired with base unit 120. And the handset 110 can be determined to be close to each other. If it is valid, the process returns to step S2-14 to continue the processing.

  When the slave unit identifier received in step S2-17 does not match the slave unit identifier stored in master unit storage unit 123, master unit 120 determines that the received slave unit identifier is not valid and the paired master unit It is determined that 120 and slave unit 110 are separated from each other, and an alarm is output from output unit 127 in step S2-13. In addition, the main | base station 120 may notify a warning to the report destination terminal device 150 through the personal computer 140, the monitoring device 130, or the like.

  On the other hand, when the monitoring apparatus 130 transmits a pair registration completion notification to the parent device 120 in step S4-3, the monitoring device 130 requests a child device identifier from the child device 110 and requests a parent device identifier from the parent device 120 in step S4-4. To do.

  When receiving the request for the slave unit identifier in step S 3-1, the slave unit 110 reads the slave unit identifier from the slave unit storage unit 113 and transmits it to the monitoring device 130 in step S 3-2. In addition, when receiving the request for the parent device identifier in step S2-18, the parent device 120 reads the parent device identifier from the parent device storage unit 123 and transmits it to the monitoring device 130 in step S2-19.

  The monitoring device 130 determines whether or not the child device identifier received from the child device 110 and the parent device identifier received from the parent device 120 in step S4-5 are a pair stored in the monitoring device storage unit 133. When the slave unit identifier received from the slave unit 110 in step S4-5 and the master unit identifier received from the master unit 120 are not paired, the monitoring apparatus 130 separates the slave unit 110 and the master unit 120 in step S4-6. The output unit 135 outputs an alarm. Note that the monitoring device 130 may notify the alert destination terminal device 150 of an alarm via the network 160. At this time, in order for the monitoring device 130 to report an alarm to the notification destination terminal device 150, the monitoring device storage unit 133 of the monitoring device 130 has a notification destination table consisting of a parent device identifier, a notification destination name, and an e-mail address. have. The processing unit 132 makes a report to the report destination terminal device 150 with reference to the report destination table stored in the monitoring device storage unit 133.

  FIG. 6 shows a data configuration diagram of the report destination table.

  The report destination table includes a base unit identifier, a report destination name, and an e-mail address. Note that the reporting destination may be one place or a plurality of places for one base unit identifier.

  Returning to FIG.

  Furthermore, when the monitoring device 130 cannot read the child device identifier and the parent device identifier for a certain period of time, for example, several tens of minutes to one hour, the monitoring device 130 shields the portable storage medium 101 with aluminum foil or the like and takes it illegally. It is judged that it is, and an alarm is output.

  Further, when an alarm is output, the monitoring device 130 controls the electric lock 170 via the network 160 or the like, locks the entrance, and prohibits the portable storage medium 101 from being taken outside.

  Note that a situation where the slave unit identifier received from the slave unit 110 and the master unit identifier received from the master unit 120 are not paired may be a case where only the slave unit identifier or only the master unit identifier can be acquired.

  When the slave unit identifier received from the slave unit 110 and the master unit identifier received from the master unit 120 are a pair in step S4-5, the monitoring apparatus 130 returns to step S4-4 and continues the process.

  The output unit 127 of the main unit 120 is provided with a switch SW. By operating the switch SW, the alarm output can be temporarily stopped when an alarm is output from the output unit 127. It is configured.

  When connected to the personal computer 140 again, the parent device 120 automatically deletes the child device identifier stored in the parent device storage unit 123 and stops outputting the alarm from the output unit 127. As a result, data can be written to another portable storage medium 101.

  According to the present embodiment, the slave unit 110 mounted on the portable storage medium 101, the master unit 120 worn by the carrier, and the monitoring device 130 that monitors the slave unit identifier and the master unit identifier are allowed. By monitoring the removal of the portable storage medium 101 outside the room, it is attempted to carry out only the portable storage medium 101, or the slave unit 110 or the master unit 120 is lost or misplaced, and the slave unit 110 cannot be detected. When an illegal transport such as unloading is performed in this way, an alarm is output, so that an illegal transport can be warned and illegal data leakage can be prevented.

  In this embodiment, the parent device 120 is connected to the personal computer 140. However, a device monitoring device that monitors data transfer to the portable storage medium 101, removal from the personal computer 140, etc., separately from the parent device 120. May be provided.

  FIG. 7 shows a system configuration diagram of another embodiment of the present invention. In the figure, the same components as those in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

  The portable object monitoring system 200 according to the present embodiment has a configuration in which a device monitoring device 210 is provided separately from the parent device 120.

  The device monitoring device 210 is connected to a USB port, a PC card slot, or the like of the personal computer 140, and is a device that monitors data transfer in the personal computer 140, removal from the personal computer 140, etc., and performs wireless communication with the parent device 120.

  FIG. 8 is a block configuration diagram of the device monitoring apparatus 210.

  The device monitoring apparatus 210 includes a communication unit 211, a processing unit 212, a storage unit 213, an interface 214, a USB port 215, and the like.

  The communication unit 211 is a device for performing wireless communication with the parent device 120. The processing unit 212 executes processing for transferring data to the portable storage medium 101 in the personal computer 140 based on a program stored in the storage unit 213 or the like.

  The storage unit 213 includes a memory and the like, and stores a program executed by the processing unit 212, a child device identifier acquired from the child device 110, a parent device identifier acquired from the parent device 120, and the like.

  The interface 214 is a device that interfaces with the personal computer 140 via the USB port 215.

  Next, the operation at the time of data transfer to the portable recording medium 101 in the personal computer 140 of this embodiment will be described.

  FIG. 9 is a diagram for explaining the operation of another embodiment of the present invention.

  When the personal computer 140 receives a data transfer instruction to the portable storage medium 101 in step S4-21, the execution of the data transfer is set in a standby state in step S4-22. When the device monitoring apparatus 210 detects a data transfer instruction to the portable storage medium 101 of the personal computer 140 in step S5-1, the device monitoring apparatus 210 determines whether or not the parent device 120 is connected to the personal computer 140 in step S5-2.

  If it is determined in step S5-2 that the parent device 120 is connected to the personal computer 140, the device monitoring apparatus 210 waits for a human body attachment notification signal to be supplied from the parent device 120 in step S5-3. When the base unit 120 is detached from the personal computer 140 in step S2-21 and attached to the human body, the base unit 120 detects that the human body detection unit 126 is attached to the human body, and in step S2-22, the base unit 120 detects that the device monitoring apparatus 210 is attached. A human body wearing signal is transmitted.

  When device monitoring apparatus 210 receives a human body wearing signal from parent device 120 in step S5-3, device monitoring apparatus 210 transmits a data transfer permission signal to personal computer 140 in step S5-4.

  When receiving the data transfer permission signal from the device monitoring apparatus 210 in step S4-23, the personal computer 140 transfers the data to the portable storage medium 101 in step S4-24. When the data transfer to the portable storage medium 101 is completed in step S4-25, the personal computer 140 notifies the device monitoring apparatus 210 of a data transfer completion signal in step S2-26.

  When the device monitoring apparatus 210 receives a data transfer completion signal from the personal computer 140 in step S5-5, the device monitoring apparatus 210 requests a slave unit identifier from the slave unit 110 in step S5-6. When receiving the request for the slave unit identifier from the device monitoring apparatus 210 in step S 3-1, the slave unit 110 reads the slave unit identifier from the slave unit storage unit 113 and transmits it to the device monitor unit 210 in step S 3-2.

  Upon receiving the slave unit identifier from slave unit 110 in step S5-7, device monitoring apparatus 210 transmits the slave unit identifier received in step S5-8 to master unit 120, and the slave unit received in step S5-9. A pair in which the identifier and the connected master unit identifier are associated is transmitted to the monitoring apparatus 130.

  When the monitoring device 130 receives the pair of the child device identifier and the parent device identifier in step S1-21, the monitoring device 130 registers the pair of the child device identifier and the parent device identifier in the monitoring device storage unit 133 in step S1-22. The data transfer process in the monitoring device 130 ends. As described above, the monitoring device 130 reads the slave device identifier from the slave device 110, reads the master device identifier from the master device 120, reads the slave device identifier, the master device identifier, and the monitoring device storage. The state of the portable storage medium 101 and the parent device 120 is monitored based on the pair of the child device identifier and the parent device identifier stored in the unit 133.

  Further, when receiving the slave unit identifier from the device monitoring apparatus 210 in step S2-22, the base unit 120 reads the master unit identifier from the base unit storage unit 123 in step S2-23 and receives the slave unit identifier received from the device monitoring apparatus 210. A pair with the machine identifier is created and stored in the parent machine storage unit 123 in step S2-24. Thus, the process at the time of data transfer in the master unit 120 is completed. For example, as shown in FIG. 5, steps S2-14 to S2-13, the parent device 120 uses the parent device identifier and the child device identifier stored in the parent device storage unit 123 to Judgment of legitimacy and processing to output alarm.

  Next, an arrangement example of the monitoring device 130 will be described.

  FIG. 10 is a diagram for explaining an example of the arrangement of the monitoring device 130.

  FIG. 10 shows an arrangement in which the monitoring device 130 is installed near the doorway, and the electric lock 170 provided on the door 180 provided at the doorway is controlled.

  If the transporter 190 transports in the vicinity of the parent device 120 and the portable storage medium 101 paired with the parent device 120, it can be determined that the transporter 190 is a legitimate transporter, so the monitoring device 130 does not output an alarm. The electric lock 170 is in an unlocked state, and the carrier 190 can open the door 180 and go out with the portable storage medium 101.

  On the other hand, if the transporter 190 transports only the portable storage medium 101 and goes outside, it can be determined that the transporter 190 is an unauthorized transporter, so that the monitoring device 130 outputs an alarm and the electric lock 170 is locked. To control. As a result, the carrier 190 cannot open the door 180 and go out with the portable storage medium 101.

  FIG. 11 is a diagram for explaining another example of the arrangement of the monitoring device 130.

  In the case where an electric lock or the like cannot be installed, for example, when a specific monitoring area A is provided on the same floor, a plurality of monitoring devices 130 are provided on the periphery of the monitoring area A as shown in FIG. The monitoring device 130 detects the identifiers of the child device 110 and the parent device 120 of the portable storage medium 101 when passing through the lower part of the monitoring device 130, and forms a pair with the parent device 120 and the parent device 120. If it is transported in close proximity, it is determined that the transporter is a valid transporter, and the monitoring device 130 does not output an alarm.

  In addition, when the monitoring device 130 passes below the monitoring device 130, the slave device identifier of only the slave device 110 of the portable storage medium 101, the master device identifier of only the master device 120, or a pair is not formed. When the slave unit identifier and the master unit identifier are detected, it is determined that the master unit 120 and the portable storage medium 101 paired with the master unit 120 are not transported close to each other. The monitoring device 130 outputs an alarm. In addition, an instruction may be transmitted from the monitoring device 130 to output a warning to the slave unit 110 and the master unit 120, and an alarm may be output from the slave unit 110 and the master unit 120.

  In addition, the arrangement | positioning method of the monitoring apparatus 130 is not limited to the form of the said FIG. 10, FIG.

  In the above embodiment, the transport of the portable storage medium 101 has been described as an example. However, the portable object is not limited to the portable recording medium 101, and various portable devices to which the slave unit 110 can be attached. Needless to say, it can be applied to type electronic devices and valuables.

  The present invention is not limited to the above-described embodiments, and it goes without saying that various modifications can be considered without departing from the gist of the present invention.
