Conventionally, computer devices such as personal computers have been used. This computer device includes USB memory, floppy disk, CD—ROM (Compact Disk Read Only Memory), DVD—ROM (Digital Versatile Disk Read Only Memory), MO (Magneto-Optical). There are various drives (drive devices) that read and write data to various external storage media such as disk!

[0003] With these various drives, data can be written to an external storage medium and copied (replicated) to another computer apparatus, or data can be read from the external storage medium to the computer apparatus.

[0004] In recent years, the protection of data is regarded as important due to the enforcement of the Personal Information Protection Law. As methods for protecting this data, various methods for preventing unauthorized copying have been proposed.

[0005] For example, data that is stored in an external storage medium unless it is a computer device that uses an authentication medium that stores an authentication key paired with an external storage medium and that has installed the authentication key from the authentication medium. Cannot be viewed! /, And a media copy protection method has been proposed! /, (See Patent Document 1).

[0006] Also, the drive ID and serial number of the computer device used by the user are heard in advance and stored in an external storage medium or a separate medium, and this drive ID and serial number are verified to prevent unauthorized copying. A method to do this has been proposed (see Patent Document 2).

[0007] However, even if these methods can prevent the computer device from reading the data from the external storage medium in which the data is stored by unauthorized copying, the data is stored in the external storage medium. Copying itself could not be prevented. For this reason, there was a problem that data could be read if it was illegally accessed to an external storage medium that illegally copied the data.

In this control unit 11, the CPU loads and starts the startup program stored in the ROM, loads and executes the OS (operating system) and application programs stored in the node disk 25, and temporarily stores the RAM. Various operations are performed using the area.

[0018] The CD drive 12 reads data (including not only pure data but also a program) stored in a CD (Compact Disc) 32 according to a control signal of the control unit 11, and reads the data into the control unit 11 To pass. The CD drive 12 is provided with a tag reader 13. The CD drive 12 also passes the tag data read by the tag reader 13 from the RFID tag 33 attached to the CD 32 to the control unit 11.

The tag reader 13 is provided in the vicinity of the tray 12a on which the CD 32 is set. this The position where the tag reader 13 is provided is preferably in the vicinity of a rotation drive unit (not shown) that holds and rotates the center of the CD 32 with the tray 12a closed and the CD 32 taken in. The disc-shaped CD 32 is provided with an RFID tag 33 in the vicinity of the center. Therefore, the RFID tag 33 and the tag reader 13 are configured so as to be close to each other regardless of the position at which the rotating CD 32 is stopped.

The FD drive 14 reads / writes data (including not only pure data but also programs) from / to an FD (flexible disk) 34 in accordance with a control signal from the control unit 11. Further, the FD drive 14 is provided with a tag reader 15, and tag data read from the RFID tag 35 attached to the FD 34 by the tag reader 15 is also passed to the control unit 11.

The tag reader 15 is provided inside the FD drive 14. The position where the tag reader 15 is provided is preferably a position in the vicinity of the RFID tag 35 of the FD 34 in a state where the FD 34 is taken inside. Also, the FD 34 is equipped with an RFID tag 35 at a position V that does not damage the internal magnetic disk (not shown)!

[0022] The USB terminal 16 is a terminal to which a USB device such as the USB memory 36 is connected. The connected USB device is controlled according to the control signal of the control unit 11. A tag reader 17 is provided in the vicinity of the USB terminal 16. The tag reader 17 passes the tag data read from the RFID tag 37 attached to the USB memory 36 to the control unit 11.

[0023] The tag reader 17 is arranged symmetrically outside the two USB terminals 16 provided side by side at a position near the RFID tag 37 of the USB memory 36 connected to the USB terminal 16. ing. Further, the USB memory 36 is provided with an RFID tag 37 in the vicinity of the connection portion 36a connected to the USB terminal 16! /.

[0024] These RFID tags 33, 35, 37 are composed of an IC chip and an antenna. In the non-volatile memory in the IC chip, owner identification information such as an employee number for identifying the owner is recorded in advance. Therefore, when reading tag data from the tag readers 13, 15, 17 (or RFID tags 33, 35, 37), it is possible to read the owner identification information contained in the tag data. 11 can specify the external storage medium owned by this owner-specific information.

The keyboard connection terminal 21 is a terminal for connecting a keyboard. This keyboard connection The terminal 21 passes an input signal from the keyboard to the control unit 11.

The mouse connection terminal 22 is a terminal for connecting a mouse. The mouse connection terminal 22 passes an input signal from the mouse to the control unit 11.

[0026] The monitor connection terminal 23 is a terminal for connecting a monitor such as a CRT monitor or a liquid crystal monitor. This monitor connection terminal 23 passes the image signal from the control unit 11 to the connected monitor.

The power supply unit 24 rectifies and transforms a 100-volt AC power supply to supply power to various units such as the control unit 11.

The hard disk 25 reads and writes data according to the control signal from the control unit 11. The hard disk 25 stores an OS and various application programs, and also stores a data processing restriction program that restricts data processing such as data writing and reading.

The PCI card 27 is a card for expansion functions such as a LAN card, a modem card, and a TV capture card. The PCI card 27 operates according to the control signal from the control unit 11.

As shown in FIG. 1, an electromagnetic wave prevention sheet 42 is provided between the mother board constituting the control unit 11 and the CD drive 12 and the FD drive 14. The electromagnetic wave prevention sheet 42 is provided without a gap so as to completely separate the CD drive 12 and the FD drive 14 from the mother board constituting the control unit 11.

[0029] Further, between the CD drive 12 and the FD drive 14, an electromagnetic wave prevention sheet 43 is provided without a gap so as to completely separate them.

An electromagnetic wave prevention sheet 41 is provided between the two USB terminals 16 and 16. In addition, the base casing 10a and the cover casing 10b are provided with electromagnetic wave prevention sheets 44 and 45 over the entire inner surface.

These electromagnetic wave prevention sheets 4;! To 45 are made of a metal member such as aluminum, a material containing carbon in aluminum, permalloy, or a material having a multilayer structure obtained by polymerizing these.

[0030] Thus, by providing the electromagnetic wave prevention sheet 4;!-45, the tag reader 13, 1 5 and 17 can be reliably separated from each other to prevent contactless communication with RFID tags other than the RFID tags 33, 35, and 37 that should be contactlessly communicated.

FIG. 3 is a flowchart showing the operation of the control unit 11 by the data processing restriction program. This data processing restriction program restricts data processing when data is read from and written to the external storage media CD32, FD34, and USB memory 36. The data processing restriction program is incorporated in a driver program for operating each device (CD drive 12, FD drive 14, USB terminal 16). As a result, the control unit 11 has a configuration in which data processing for each device cannot be executed unless the data restriction program is executed. Therefore, it is preferable that the data processing for each device can be executed only by a dedicated program of each device, for example, and cannot be executed by a normal file operation program attached to the OS of the personal computer 1 or other programs.

The control unit 11 executes the data processing restriction program, and accepts a data processing request by an operation of a mouse or keyboard user (step S 1).

The control unit 11 uses a tag reader (13, 15 or 17 force) provided in a device (CD drive 12, FD drive 14 or USB terminal 16 force) to execute the requested data processing. The tag data is read from the RFID tag (any one of 33, 35, and 37) (step S2). If the device is a CD drive 12 at the time of reading, the tag data is read from the RFID tag 33 while the rotation of the rotation drive unit is stopped and the CD 32 is stopped.

[0033] The control unit 11 determines whether or not the tag is a legitimate RFID tag based on the read tag data (step S3). This determination can be made by storing a predetermined genuine ID in the RFID tag and determining whether or not this genuine ID exists. As another method, this determination can be performed by storing a number sequence processed according to a predetermined rule in an RFID tag and determining whether this number sequence conforms to the above rule. As another method, this determination is performed by storing the genuine product IDs of all external storage media (CD32, FD34, and USB memory 36 in this embodiment) in a storage means such as the hard disk 25. This can be done by checking whether it matches the regular product ID. In this way, the force S can be determined by an appropriate method. [0034] If it is determined that the product is genuine (step S4: YES), the control unit 11 executes the requested data processing (data writing processing and reading processing) (step S5), and data processing execution record Is saved as a history (step S6), and the process ends. The information stored as this data processing execution record includes the owner identification information read from the RFID tags 33, 35, 37, processing information indicating which data was written to or read from which device, and information such as the execution date and time. It is good to compose with.

If it is determined that the product is not a regular product (step S4: NO), the control unit 11 displays an error message on the monitor connected to the monitor connection terminal 23 (step S7), and ends the process.

[0036] With the configuration and operation described above, the data processing itself for all external storage media (CD32, FD 34, and USB memory 36 in this embodiment) can be restricted, and the security level can be improved.

[0037] With the write restriction, important data such as personal information and confidential information stored in the hard disk 25 of the personal computer 1 can be prevented from being illegally copied by downloading from the server. Due to this write restriction, for example, the external storage media that can be used are limited to specific ones within the company, and if this external storage medium is not used, data cannot be copied to the external storage medium, and it is possible to operate in a single operation. .

[0038] In addition, the read restriction can prevent a virus that executes a destructive activity from being copied from the external storage medium to the hard disk 25 of the personal computer 1 without the user's knowledge. In other words, since it cannot be handled as a regular external storage medium, data cannot be transferred to the personal computer 1 from an external storage medium that the user has brought personally. For this reason, it is possible to prevent the in-house computer 1 from being infected with a wine by bringing in personal data from a personal computer.

[0039] In addition, since all tag readers 13, 15, 17 (or electromagnetic wave prevention sheets 41, 42, 43, 44, 45ί are separated from each other, RFID tags 33, 35, 37 of different external storage media are used. It is possible to prevent the tag data from being read, especially when an external storage medium (for example, FD) without an RFID tag is set and the regular external storage medium (FD32) is brought close to the tag reader unit (tag reader 13). Thus, it is possible to prevent illegal acts by recognizing only the tag data and writing (or reading) the data to a different external storage medium. [0040] Further, by referring to the owner specifying information, it is possible to specify who has performed data processing and the ability S to specify. This makes it possible to identify who copied the data illegally if the employee copied the data illegally.

[0041] Note that the person who performed the data processing is specified by logging in the registered user when operating the personal computer 1 that is not the owner identification information, and logging in when storing the history! You can also identify it by memorizing it.

[0042] In this embodiment, CD32, FD34, and USB memory 36 are used as external storage media. However, the present invention is not limited to this, and various types such as CD-R, CD-RW, RVD-ROM, DVD-RAM, etc. External storage media can be targeted.

[0043] The external storage medium is not limited to an external storage medium that stores data by magnetism or the like, and may include a print medium to be printed. In this case, if a printer that prints data is equipped with a tag reader, a printing medium such as paper is equipped with an RFID tag, and a printout is requested as data processing, steps S1 to S7 are executed. Good.
