Description

Individual data management system

The present invention relates to an individual data management system for managing an individual by providing the individual with a microchip and storing data on the individual on the microchip.

Conventionally, an individual data management system in which a microchip such as an RFID is embedded in an individual such as an experimental animal and read by a reader (scanner) is known. As such an individual data management system, it has a function of reading the identification number of the microchip with a reader, and on the basis of the identification number, the database is accessed from the terminal device having the input unit, and the laboratory animals and the like accumulated in the database What obtains individual data is known. (See, for example, JP 2007-222138A).

In such an individual management system, the microchip stores only the microchip-specific code stored in a state that is not rewritable in advance for each microchip, while the individual's medical history or Additional data over time such as treatment records and data such as individual pedigrees are stored in a database.

As described above, in the conventional individual management system, since the data related to the individual is stored only in the database, the reader for reading the identification number of the microchip is connected to the database in which the individual data is stored through the communication line. Without it, individual data could not be displayed.

For this reason, even if the microchip data is read and browsed on the spot, the identification number as the microchip unique data can only be viewed, and if there is no terminal device that can access the database, individual data is required. Even so, individual data could not be obtained immediately.

In addition, because individual data is sequentially stored in the database, if the date and time when the individual data was written in the database is old and the latest data is not stored in the database, the latest data The problem may not be.

As a countermeasure, it has been proposed to provide a rewritable area on a microchip provided in an individual, write the latest data on a rewritable area on a daily basis, and read and display the data in a reader / writer (for example, JP 2014-27920A).

However, if a rewritable area is provided on the microchip provided in an individual, any person can freely access the rewritable area as long as the reader / writer device connected to the terminal device is owned. Protecting individual data becomes difficult.

An object of the present invention is to provide an individual data management system that protects individual data written in a rewritable area of a microchip and can improve daily convenience.

According to an aspect of the invention, an individual data management system has a rewritable area that can be rewritten by external wireless communication and a non-rewritable area that cannot be rewritten by external wireless communication, and is provided in an individual. A reader / writer device that receives data stored in the microchip by wireless communication or transmits data for rewriting to the rewritable area of the microchip, and is connected to the reader / writer device by wire or wirelessly, A terminal device having an input unit for inputting data, and a display unit for displaying data input by the input unit and data received by the reader / writer device (20), and the rewriting of the microchip The rewrite restriction area that requires a rewrite password when rewriting the available area It is provided in all or part of the rewritable area.

As shown in FIG. 1 and FIG. 2, the individual data management system 10 includes a microchip 11 provided on an individual 9 (FIG. 2) such as an experimental animal. The microchip 11 in the present embodiment is embedded in the individual 9 using a syringe-type embedding machine (not shown). FIG. 2 shows a case where the microchip 11 is embedded in the neck of a dog that is an experimental animal.

The microchip 11 has a chip antenna 12 (FIG. 1) made of a coil and an IC chip 13 (FIG. 1) connected to the chip antenna 12. The chip antenna 12 and the IC chip 13 are sealed in a glass capsule, and the external appearance of the microchip 11 is a rod having a circular cross section with an outer diameter of about 1.5 mm so that it can be embedded in the individual 9.

As shown in FIG. 1, the IC chip 13 is connected to a power supply circuit 13a, a radio frequency (RF) circuit 13b, a modulation circuit 13c, a demodulation circuit 13d, a chip control circuit 13e, and a chip control circuit 13e. And a memory 13f. The power supply circuit 13 a includes a capacitor (not shown), and the capacitor forms a resonance circuit together with the chip antenna 12. The capacitor is charged with electric power generated by electromagnetic induction when the chip antenna 12 receives a radio wave having a specific resonance frequency. The power supply circuit 13a rectifies and stabilizes the power, supplies it to the chip control circuit 13e, and activates the IC chip 13.

The memory 13f includes a ROM (read-only memory), a RAM (random-access memory), and an EEPROM (electrically-erasable-programmable-read-only memory). Under the control of the chip control circuit 13e, the memory 13f reads stored data and writes commands from the reader / writer device 20 in response to a read command by radio wave data communication from the reader / writer device 20 described later. Write the data accordingly.

The storage area of the memory 13f includes unique data unique to the microchip 11, and includes a non-rewritable area that cannot be rewritten by external wireless communication, and a rewritable area that can be rewritten by external wireless communication. .

The chip antenna 12 generates an induced electromotive force by a magnetic field generated by a transmission / reception antenna 22 as a magnetic field generation unit of the reader / writer device 20. The chip control circuit 13e activated by the induced electromotive force reads the unique data stored in the non-rewritable area of the memory 13f and the individual data stored in the rewritable area, and sends these data to the external reader / writer device 20. Send data.

On the other hand, when the individual data generated by the reader / writer device 20 is new data under the control of the control unit 27 of the reader / writer device 20, the rewritable area of the memory 13f is converted to the individual data as new individual data. To remember.

This embodiment is characterized in that a rewrite restriction area that requires a rewrite password at the time of rewriting is formed in all or part of the rewritable area. In the present embodiment, a case where the entire rewritable area is a rewrite restriction area is shown.

The unique data written in the non-rewritable area is, for example, a unique 15-digit identification number provided for each microchip 11 when the microchip 11 is manufactured.

The individual data written in the rewritable area is, for example, animal species, strain name, sex category, medication name, pet name, date of birth, rabies vaccination history, vaccine administration data, emergency contact information, and the like.

The rewrite password necessary for rewriting the rewritable area of the microchip 11 is stored in the microchip 11 in an unreadable manner. The microchip 11 is provided with a rewrite password identification unit 13g that compares data input from an input unit 31 of the terminal device 30 described later with a rewrite password.

The rewrite password identification unit 13g is one of programs in the chip control circuit 13e. When the rewrite password identification unit 13g determines that the input data input from the input unit 31 of the terminal device 30 matches the rewrite password, the microchip 11 is used for rewriting transmitted from the reader / writer device 20. Data is written in the rewritable area of the memory 13f.

As shown in FIG. 1, the individual data management system 10 receives data stored in the microchip 11 by wireless communication, or transmits data for rewriting to a rewritable area of the memory 13f of the microchip 11. A reader / writer device 20 is provided. In the present embodiment, the reader / writer device 20 is a small portable terminal as shown in FIG.

The reader / writer device 20 includes an interface 21 for detachably connecting to a terminal device 30 by wire, a transmission / reception antenna 22 for receiving data from the microchip 11, a power supply circuit 23 having a battery, and a radio frequency (RF). ) Circuit 24, modulation circuit 25, demodulation circuit 26, control unit 27 connected to terminal device 30 via interface 21, and memory 27 a connected to control unit 27.

The transmitting / receiving antenna 22 generates a magnetic field, generates a self-induced electromotive force in the chip antenna 12 of the microchip 11 by the magnetic field, and receives data from the microchip 11 transmitted by the power.

The memory 27a is the same as the memory 13f of the microchip 11, and includes a ROM, a RAM, and an EEPROM. The control unit 27 reads the data stored in the memory 13 f of the microchip 11, stores the read data in the memory 27 a, and transmits the data to the terminal device 30 in response to a request from the terminal device 30.

The memory 27a stores a connection password and a transmission password. The reader / writer device 20 further includes a display unit 28 and an operation switch 29. The display unit 28 displays all or part of the data stored in the memory 27a. The operation switch 29 is used to perform an operation of displaying data on the display unit 28, an operation of supplying power to the transmission / reception antenna 22 to generate a magnetic field, and an operation of receiving data of the microchip 11 through the transmission / reception antenna 22. is there.

In the present embodiment, as shown in FIG. 2, a liquid crystal display panel is employed for the display unit 28 of the reader / writer device 20. In the vicinity of the display unit 28, a status lamp 28b for notifying the operation status of the reader / writer device 20 to the outside and a mode lamp 28a for notifying the state of the reader / writer device 20 to the outside are arranged. These

lamps

28a and 28b are controlled by the control unit 27 (FIG. 1).

On the opposite side of the display unit 28 from the

lamps

28a, 28b, an UP / DOWN button 29a is arranged. The button 29a can be operated to scroll data displayed on the display unit 28 in the vertical direction. Under the display unit 28, a power button 29e and a mode button 29d belonging to the operation switch 29 are arranged. By operating the mode button 29d, the mode can be switched to a reading operation mode for reading individual data from the microchip 11 to the reader / writer device 20, and a writing operation mode for writing individual data to the storage unit of the microchip 11.

Whether the reading operation mode or the writing operation mode is selected can be visually confirmed by the mode lamp 28a. By operating the start / stop button 29b belonging to the operation switch 29 in the state where the mode is switched, it is possible to start / stop the read / write processing.

As shown in FIG. 1, the reader / writer device 20 compares the data input from the input unit 31 of the terminal device 30 connected to the reader / writer device 20 with a connection password and a transmission password stored in the memory 27 a. A password identification unit 27b and a transmission password identification unit 27c are provided.

The connection password identification unit 27b and the transmission password identification unit 27c are programs stored in the control unit 27, respectively. When the reader / writer device 20 determines that the input data input from the input unit 31 of the terminal device 30 matches these passwords, the reader / writer device 20 permits connection with the terminal device 30 and the microchip 11 Data for rewriting is received from the terminal device 30 in the rewriting restricted area of the memory 13 f and transmitted to the microchip 11.

1 and 2, the individual data management system 10 includes a terminal device 30 connected to the reader / writer device 20 by wire or wirelessly. The terminal device 30 includes an input unit 31 for inputting data, and a display unit 34 for displaying data input by the input unit 31 and data received by the reader / writer device 20.

The input unit 31 is used for inputting a password for authentication and inputting data on a new registration screen or update registration screen of individual data. The terminal device 30 includes a power supply circuit 32, a memory 33 that stores data input from the input unit 31, and transmits the data to the reader / writer device 20, or is received by the reader / writer device 20 and stored in the memory 33. And a terminal control unit 35 that reads the data and displays the data on the display unit 34. As shown in FIG. 2, the display unit 34 is a relatively large liquid crystal display, and the terminal control unit 35 (FIG. 1) is provided inside the box 36.

As shown in FIG. 1, the terminal control unit 35 is provided with a password setting unit 35a for setting a rewrite password using unique data stored in a non-rewritable area of the memory 13f of the microchip 11. In the initial setting of the microchip 11, the rewrite password set by the password setting unit 35 a is stored in the microchip 11.

When the transmission password identification unit 27c of the reader / writer device 20 determines that the input data from the input unit 31 of the terminal device 30 matches the transmission password, the reader / writer device 20 is input from the input unit 31. Along with the data for rewriting, the rewrite password set by the password setting unit 35a of the terminal device 30 is received from the terminal device 30 and transmitted to the microchip 11.

The rewrite password identification unit 13g of the microchip 11 compares the rewrite password transmitted from the reader / writer device 20 with the rewrite password stored in the microchip 11.

Next, how to use the individual data management system 10 will be described.

In order to use the individual data management system 10, initial settings of the microchip 11 and the reader / writer device 20 are required. Specifically, the rewrite password is stored in the microchip 11, and the connection password and the transmission password are stored in the memory 27 a of the reader / writer device 20.

Figure 3 shows the initial setting procedure. At the time of initial setting, the individual 9 in which the microchip 11 is embedded, the reader / writer device 20, and the terminal device 30 are in a positional relationship in which communication is possible. Specifically, the terminal device 30 and the reader / writer device 20 are connected by wire, and the reader / writer device 20 and the individual 9 are in a state where they can be connected wirelessly.

First, the power of the terminal device 30 and the reader / writer device 20 is turned on, and the respective control units 27 and 35 are activated. The administrator inputs a connection password and a transmission password, which are combinations of arbitrary numbers and characters, from the input unit 31 of the terminal device 30 (S01, S04). Next, by turning on the switches necessary for storage (S02, S05), they are stored in the memory 27a of the reader / writer device 20 as data that cannot be read or rewritten (S03, S06). The connection password and the transmission password may be the same as or different from each other.

The rewrite password may be set to any combination of numbers and characters. However, in the present embodiment, the rewrite password set by the password setting unit 35a is stored in the microchip 11 in the initial setting. Specifically, a unique 15-digit identification number provided for each microchip 11 is written into the non-rewritable area of the memory 13f in the microchip 11 at the time of manufacture. The reader / writer device 20 reads the identification number (S07), and the password setting unit 35a of the terminal device 30 converts the identification number with a predetermined algorithm to obtain a rewritten password (S08). The reader / writer device 20 transmits the rewrite password thus obtained to the microchip 11, and the microchip 11 reads the rewrite password and stores it in a non-rewritable state (S09).

Since the 15-digit identification number written in the non-rewritable area of the memory 13f of the microchip 11 is assigned to each microchip 11, a plurality of identical ones do not exist. Therefore, a single identification number is assigned to one microchip 11, and a single rewritten password obtained by converting the identification number with a predetermined algorithm is also a single one. For this reason, the rewrite password set by the password setting unit 35a of the terminal device 30 is paired with the identification number and becomes a single one, and there is no plurality of the same ones.

The microchip 11 in which the rewrite password is stored in the initial setting in this way is embedded in an individual 9 such as an experimental animal, and the subsequent management is performed.

Next, daily data management by the individual data management system 10 will be described. FIG. 4 shows a procedure for displaying individual data.

First, the terminal device 30 and the reader / writer device 20 are connected by wire, and both control units 27 and 35 are activated by turning on the power of both. Then, a login screen as an administrator authentication screen (not shown) is displayed on the display unit 34 in the terminal device 30. On the authentication screen, input items for the connection password are displayed (S11).

The administrator inputs the connection password set in the initial setting from the input unit 31 of the terminal device 30 (S12). Then, the connection password identifying unit 27b of the reader / writer device 20 connected to the terminal device 30 by wire connects the input data input from the input unit 31 of the terminal device 30 and the connection password stored in the memory 27a of the reader / writer device 20. Are determined to match (S13), and if it is determined to match, the connection between the terminal device 30 and the reader / writer device 20 is permitted (S14).

Next, the operation switch 29 of the reader / writer device 20 is operated to execute the reading process of the unique data stored in the non-rewritable area of the memory 13f of the microchip 11 and the individual data stored in the rewritable area (S15). ).

When the reader / writer device 20 reads the data stored in the memory 13f of the microchip 11 in this way, the reader / writer device 20 temporarily stores the data in the memory 27a and receives individual requests from the terminal device 30. Thus, the data is transmitted to the terminal device 30. In the terminal device 30, the requested individual data is displayed on the display unit 34 by the input from the input unit 31 (S 16), and the content is recognized by the administrator.

In the present embodiment, a rewrite restriction area that requires a rewrite password is required for rewriting in the entire rewritable area of the memory 13f of the microchip 11, so that data is stored in the rewrite restriction area or is already stored. When rewriting data, a rewrite password is required.

Data stored in the rewrite restriction area and data for rewriting already stored data are input from the input unit 31 of the terminal device 30, and the reader / writer device 20 is interposed between the terminal device 30 and the microchip 11. Intervene. Therefore, in this embodiment, a transmission password for transmitting data for rewriting input from the input unit 31 of the terminal device 30 from the terminal device 30 to the reader / writer device 20 is stored in the reader / writer device 20, and The writer device 20 is provided with a transmission password identification unit 27c.

Next, a procedure for rewriting the individual data stored in the microchip 11 will be described with reference to FIG. When the individual data stored in the microchip 11 is rewritten, the terminal device 30 and the reader / writer device 20 are connected by wire as in the initial setting, and the reader / writer device 20 and the individual 9 are wirelessly connectable. is there.

When the administrator makes an input for rewriting individual data from the input unit 31 of the terminal device 30, a data input screen describing the rewriting content is displayed on the display unit 34 of the terminal device 30 (S21). The administrator inputs data to be stored in the rewritable area of the microchip 11 or data for rewriting already stored data from the input unit 31 of the terminal device 30 (S22).

When the input of the individual data is completed and a message to that effect is input from the input unit 31, a transmission password input screen is displayed on the display unit 34 of the terminal device 30 (S23). The administrator inputs the transmission password set at the time of initial setting from the input unit 31 of the terminal device 30. The individual data and the transmission password input from the input unit 31 are temporarily stored in the memory 33 of the terminal device 30.

Next, when the operation switch 29 of the reader / writer device 20 is operated to transmit the individual data for rewriting input from the input unit 31 to the microchip 11, the control unit 27 of the reader / writer device 20 causes the terminal device to operate. The transmission password stored in the memory 33 is read. Then, the transmission password identifying unit 27c of the reader / writer device 20 determines whether or not the transmission password read from the memory 33 of the terminal device 30 matches the transmission password stored in the memory 27a of the reader / writer device 20 by default. Determine. When the transmission password identification unit 27c determines that they match (S24), the reader / writer device 20 receives the individual data for rewriting input from the input unit 31 of the terminal device 30 and stored in the memory 33. Is transmitted from the terminal device 30 to the microchip 11 (S27).

On the other hand, the password setting unit 35a of the terminal device 30 reads the unique data stored in the non-rewritable area of the microchip 11 and read by the reader / writer device 20 (S25), and sets the rewrite password from the identification number that is the unique data ( S26).

Since the rewrite password obtained by the password setting unit 35a is obtained by converting the unique data stored in the microchip 11 with a predetermined algorithm, the same rewrite password is obtained if the unique data is the same. Therefore, the rewrite password obtained by the password setting unit 35a is the same as the rewrite password stored in the microchip 11 by default.

The rewrite password obtained by the password setting unit 35a is received by the reader / writer device 20 from the terminal device 30 and transmitted to the microchip 11 together with the rewriting data input from the input unit 31 of the terminal device 30 (S27). ).

On the other hand, in the microchip 11 brought close to the reader / writer device 20, an induced electromotive force is generated in the chip antenna 12 by the magnetic field generated by the transmission / reception antenna 22 of the reader / writer device 20, and the chip control circuit 13e is activated by this induced electromotive force. To do.

The rewrite password identification unit 13g in the chip control circuit 13e compares the rewrite password transmitted from the reader / writer device 20 with the rewrite password stored in the memory 13f of the microchip 11 (S28). If it is determined as a result of the comparison that the two match, the chip control circuit 13e writes the data for rewriting transmitted from the reader / writer device 20 in the rewrite restriction area of the memory 13f (S29). .

According to the above embodiment, the following effects are exhibited.

In the individual data management system 10, a rewritable restriction area that requires a rewrite password at the time of rewriting is provided in the rewritable area of the microchip 11, so that an individual stored in the rewrite restriction area by a third party who does not know the rewrite password Data is prevented from being rewritten. Thereby, the individual data written in the rewritable area of the microchip 11 is protected, and daily convenience can be improved.

In addition, a transmission password for transmitting data for rewriting input from the input unit 31 of the terminal device 30 to the reader / writer device 20 from the terminal device 30 is stored in the reader / writer device 20, and a transmission password identification unit 27c is stored in the reader / writer. The reader / writer device 20 is provided in the device 20 and receives the data for rewriting input from the input unit 31 of the terminal device 30 from the terminal device 30 and transmits it to the microchip 11 when the transmission passwords match. To do. This prevents the individual data stored in the rewrite restriction area from being rewritten not only by the rewrite password but also by a third party who does not know the transmission password. Thereby, the individual data written in the rewritable area of the microchip 11 is more reliably protected.

In addition, since the terminal device 30 is provided with a password setting unit 35a for setting a rewrite password using unique data stored in the non-rewritable area of the microchip 11, if the transmission password matches, the transmission password identification unit 27c When the determination is made, the reader / writer device 20 receives the rewrite password set by the password setting unit 35 a together with the rewrite data input from the input unit 31 from the terminal device 30 and transmits it to the microchip 11. Since such a password setting unit 35a is provided, only a transmission password is required to be input from the input unit 31 of the terminal device 30 even though a transmission password is required in addition to the rewrite password. Convenience can be improved.

In addition, since the password setting unit 35a is provided in the terminal device 30, rewriting of individual data stored in the rewrite restriction area from a terminal device that is not provided with the password setting unit 35a is prohibited.

In addition, the reader / writer device 20 needs to receive the rewrite password set by the password setting unit 35a from the terminal device 30 and transmit it to the microchip 11 together with the data for rewriting. For this reason, in a reader / writer device that does not transmit a rewrite password to the microchip 11, rewriting of individual data written in the rewrite restricted area of the microchip 11 is prohibited.

Therefore, the terminal device 30 and the reader / writer device 20 that can rewrite the individual data written in the rewrite restriction area of the microchip 11 are specified, and the individual is not used by a third party who does not have the terminal device 30 or the reader / writer device 20. Rewriting of data is surely prevented. Thereby, the individual data written in the rewritable area of the microchip 11 can be surely protected, and the daily convenience can be further improved.

In the above-described embodiment, the case where the password setting unit 35a is provided in the terminal device 30 and the rewritten password obtained thereby is stored in the microchip 11 has been described. Instead of this, the administrator may arbitrarily set a rewrite password without storing the password setting unit 35 a in the terminal device 30, and the rewrite password may be stored in the microchip 11. In this case, the rewrite password is performed by inputting from the input unit 31 of the terminal device 30, and the reader / writer device 20 receives the rewrite password input from the input unit 31 together with the data for rewriting. Are transmitted to the microchip 11. Even in this case, rewriting of the individual data stored in the rewrite restriction area is prohibited by a third party who does not know the rewrite password.

In the above-described embodiment, the case where the entire rewritable area is the rewritable restriction area has been described. Instead of this, a rewrite restriction area that requires a rewrite password at the time of rewriting may be provided in a part of the rewritable area.

The embodiment of the present invention has been described above. However, the above embodiment only shows a part of application examples of the present invention, and the technical scope of the present invention is limited to the specific configuration of the above embodiment. Absent.
