The present invention relates to a data update system capable of

  2. Description of the Related Art Conventionally, in a field where high security is required for data handling, a technology for realizing data exchange while maintaining the security has been developed.

  For example, Japanese Patent Laying-Open No. 2013-222251 (Patent Document 1) discloses a connector including a plurality of connection terminals, an IC reader, and a plurality of switches. The connection terminal is for connecting to a predetermined wiring line. The IC reader reads ID information of an IC tag built in the relay cable. Then, the IC reader starts reading the ID information when the relay cable is connected, and the plurality of switches sets the plurality of connection terminals only when authentication based on the ID information read by the IC reader is established. When the authentication based on the ID information is not established, the connection between the plurality of connection terminals and the predetermined wiring line operates so as to maintain the disconnected state. Thereby, it is possible to prevent data stored in the storage device of the information processing apparatus from being taken out by unauthorized access, for example, via a connector provided in the information processing apparatus.

  On the other hand, the present applicant has already applied the utility model to the book-type video playback device shown in Japanese Utility Model Registration No. 3172123 (Patent Document 2) and the video playback device shown in Utility Model Registration No. 3178367 (Patent Document 3). I have applied for registration.

JP 2013-222251 A Utility Model Registration No. 3172123 Utility Model Registration No. 3178367

  In the medical field, the financial field, and the like, a manufacturer that manufactures a moving image playback device such as a video catalog stores data of a predetermined moving image in advance in the moving image playback device and provides it to a store that handles the moving image playback device. The dealer lends a video playback device to the final consumer, and the final consumer obtains various information by playing back video data using the video playback device.

  Here, in the store, since the moving image data of the moving image playback device becomes old with time, it is necessary to change the moving image data to another moving image data. Therefore, the dealer asks the manufacturer to update the video data of the video playback device, and the manufacturer prepares a commercially available memory device and a commercially available cable, and provides explanatory materials that describe how to update the video data. It was distributed to dealers and the video data of the video playback device was updated at the dealers.

  Specifically, there are two types of update methods. In the first method, the manufacturer saves the video data for update in a commercially available memory device in advance and stores the commercially available memory device in the store. Connect to the video player and perform a predetermined operation to transfer the video data of a commercially available memory device to the video player of the dealer and update it. In the second method, the manufacturer connects the above-described commercially available memory device to the commercially available terminal device prepared by the manufacturer or the commercially available terminal device of the operator, and the moving image data for update is supplied to the commercially available terminal device. Connect the commercially available terminal device to the video playback device of the dealer via a commercially available cable, perform the specified operation, and transfer the video data of the commercial terminal device to the video player of the dealer To update.

  However, on the side of the operator, it is forbidden by rule that a commercially available memory device or a commercially available terminal device is connected to a terminal device owned by the operator, and the manufacturer further notifies the operator of a commercially available memory device or a commercially available memory device. In many cases, the introduction of terminal devices as materials itself is prohibited. This is because, for example, when a commercially available memory device or a commercially available terminal device is infected with an unauthorized virus, when these are connected to the handler's terminal device, the handler's terminal device is infected with the virus, This is because the data stored in the terminal device may be leaked and altered. Therefore, there is a problem that the manufacturer cannot update the data of the video playback device of the handler using a commercially available memory device or a commercially available terminal device.

  On the other hand, in the technique described in Patent Document 1 described above, an IC reader is essential, the number of parts is large, and the cost tends to increase as a whole. Furthermore, authentication using an IC reader is required, and there is a problem that a burden is placed on the operator side.

  Therefore, the present invention has been made to solve the above-mentioned problems, and prevents outflow and falsification of data due to connection of a commercially available external memory or a commercially available external terminal, despite the simple configuration. It is an object of the present invention to provide a data update system capable of performing secure data update.

  As a result of intensive studies, the inventor has completed a new data update system according to the present invention. That is, the data update system according to the present invention is a data update system including a commercially available external terminal, a dedicated communication cable, and a data control device, wherein the commercially available external terminal includes a terminal-side storage unit that stores data, and the terminal A plurality of terminal side connection terminals respectively connected to a plurality of communication wirings from the side storage unit. The dedicated communication cable is compared with the arrangement of one of the plurality of first communication terminals having the same arrangement as the arrangement of one of the plurality of communication terminals in the commercial communication cable and the arrangement of the other plurality of communication terminals in the commercial communication cable. And a plurality of other second communication terminals having a portion in which two or more communication terminals are replaced. The data control device is connected to a device-side storage unit that stores data and a plurality of communication wires from the device-side storage unit, and is equivalent to a replacement part of a plurality of second communication terminals of the dedicated communication cable. A plurality of device side connection terminals having replacement parts, the plurality of first communication terminals are connected to the plurality of terminal side connection terminals, respectively, and the plurality of second communication terminals are connected to the plurality of device side connection terminals. And a data update control unit configured to update data in the device-side storage unit to data in the terminal-side storage unit when they are connected and receive a predetermined operation from a user.

  According to the present invention, in spite of a simple configuration, it is possible to prevent outflow and falsification of data due to connection of a commercially available external memory or a commercially available external terminal, and to perform secure data update.

Overall photograph of the dedicated communication cable of the second data update system according to the present invention (FIG. 5A), and photograph of the male and female communication terminals of the dedicated communication cable of the second data update system according to the present invention (Figure 5B).

  Embodiments of the present invention will be described below with reference to the accompanying drawings for understanding of the present invention. In addition, the following embodiment is an example which actualized this invention, Comprising: The thing of the character which limits the technical scope of this invention is not.

  A data update system according to the present invention includes a first data update system including a dedicated external memory and a data control device (for example, a moving image playback device), a second external terminal, a data control device, and a dedicated communication cable. Two types of data update systems can be assumed. First, the first data update system will be described.

<First data update system>
A first data update system 1 according to the present invention is a data update system including a dedicated external memory 10 and a data control device 11 as shown in FIG. The dedicated external memory 10 is connected to a memory-side storage unit 101 for storing data and a plurality of communication wirings 102 from the memory-side storage unit 101, respectively, and compared with the arrangement of the plurality of connection terminals 901 in the commercially available external memory 90. And a plurality of memory side connection terminals 103 having a portion in which two or more connection terminals 103a are replaced.

  Here, when the dedicated external memory 10 is a USB (Universal Serial Bus) memory (USB flash drive), the connection terminal 901 in the commercially available external memory 90 is + 5V, −D, + D, GND based on a regular standard. On the other hand, the memory side connection terminal 103 in the dedicated external memory 10 is composed of four types of + 5V, + D, −D, and GND. That is, + D and −D of the memory side connection terminal 103a are switched with respect to the connection terminal 901 of the regular standard.

  The data control device 11 is connected to a device-side storage unit 111 that stores data and a plurality of communication wirings 112 from the device-side storage unit 111, and is a replacement part equivalent to the replacement part 103a of the plurality of memory-side connection terminals 103. A plurality of device-side connection terminals 113 having 113a.

  Here, similarly to the memory side connection terminal 103, the device side connection terminal 113 is composed of four types of + 5V, + D, -D, and GND, and the device side connection terminal 113a is different from the regular standard connection terminal 901. + D and -D are interchanged.

  The memory side connection terminal 103 forms a plug, and the device side connection terminal 113 forms a socket.

  Further, when the data control device 11 has a plurality of memory side connection terminals 103 connected to the plurality of device side connection terminals 113 and receives a predetermined operation from the user, the data control device 11 receives the data in the device side storage unit 111 from the memory side storage unit 101. A data update control unit 114 for updating the data is provided.

  Thereby, in spite of a simple configuration, it is possible to prevent data leakage and falsification due to connection of a commercially available external memory, and to perform secure data update.

  That is, as shown in FIG. 2A, when the plurality of connection terminals 901 of the commercially available external memory 90 are respectively connected to the plurality of device side connection terminals 113 of the data control device 11, the device side connection terminal 113 is connected to the commercially available external memory 90. The connection terminal 901 has a replacement portion 113a. Therefore, even if the data update control unit 114 tries to access the storage unit 902 of the commercially available external memory 90 via the device side connection terminal 113, the connection between the connection terminal 901 of the commercially available external memory 90 and the device side connection terminal 113. Is not appropriate, the data update control unit 114 cannot read or write data to the storage unit 902 of the commercially available external memory 90.

  As a result, even if the manufacturer side introduces the data control device 11 (for example, a video playback device) to the handler, the commercially available external memory 90 possessed by the handler and the data control device 11 on the manufacturer side are appropriate in the first place. Since connection is not possible, data leakage and tampering due to connection between the commercial external memory 90 and the data control device 11 can be reliably prevented.

  On the other hand, when the plurality of memory side connection terminals 103 of the dedicated external memory 10 are connected to the plurality of device side connection terminals 113 of the data control device 11, respectively, as shown in FIG. This is equivalent to the replacement portion 103 a of the memory side connection terminal 103. Therefore, the connection between the memory side connection terminal 103 and the device side connection terminal 113 becomes appropriate, and the data update control unit 114 can communicate data with the dedicated external memory 10, and the memory side storage unit 101 of the dedicated external memory 10 can be communicated. Data can be read and written. As a result, the data in the device-side storage unit 111 can be updated to the data in the memory-side storage unit 101 by receiving a predetermined operation from the user.

  Even if the memory side connection terminal 103 of the dedicated external memory 10 is connected to the connection terminal of a commercially available external terminal, the memory side connection terminal 103 has the replacement portion 103a. Data communication with 10 is not possible. Even if the device-side connection terminal 113 of the data control device 11 is connected to a connection terminal of a commercially available external memory, the device-side connection terminal 113 similarly has a replacement portion 113a. Data communication with commercially available external memory is not possible.

  Thereby, even if the manufacturer introduces the data control device 11 and the dedicated external memory 10 to the handler, the handler can only update the data of the target data control device 11 using the dedicated external memory 10. Since this is not possible, secure data update can be performed.

  Further, the memory side connection terminal 103 constitutes a replacement part 103 a for the communication wiring 102 from the memory side storage unit 101, and the device side connection terminal 113 is connected to the communication wiring 112 from the device side storage unit 111. Therefore, the replacement portion 113a only needs to be configured, so that the configuration is extremely simple and has an advantage of being relatively easy to implement.

<Second data update system>
The second data update system 2 according to the present invention is a second data update system including a commercially available external terminal 20, a dedicated communication cable 21, and a data control device 22, as shown in FIG. The commercially available external terminal 20 includes a terminal-side storage unit 201 that stores data, and a plurality of terminal-side connection terminals 203 that are respectively connected to a plurality of communication wires 202 from the terminal-side storage unit 201.

  Here, the terminal-side connection terminal 203 in the commercially available external terminal 20 is configured with, for example, four types of + 5V, −D, + D, and GND based on a regular standard.

  The dedicated communication cable 21 includes a plurality of first communication terminals 211 having an arrangement equivalent to the arrangement of one of the plurality of communication terminals 911 in the commercial communication cable 91 and the other plurality of communication in the commercial communication cable 91. Compared with the arrangement of the terminals 912, the other plurality of second communication terminals 212 having a portion in which two or more communication terminals 212a are replaced are provided.

  Here, like the terminal side connection terminal 203, the 1st communication terminal 211 is comprised by four types, + 5V, -D, + D, and GND. On the other hand, the second communication terminal 212 includes four types of + 5V, + D, -D, and GND, and + D and -D of the second communication terminal 212a are interchanged with the communication terminal 911 of the regular standard. .

  The terminal-side connection terminal 203 constitutes a socket, and the first communication terminal 211 and the second communication terminal 212 constitute a plug.

  Further, the data control device 22 is connected to the device-side storage unit 221 for storing data and the plurality of communication wires 222 from the device-side storage unit 221, and the data control device 22 is connected to the plurality of second communication terminals 212 of the dedicated communication cable 21. A plurality of device-side connection terminals 223 having a replacement portion 223a equivalent to the replacement portion 212a.

  Here, like the plurality of second communication terminals 212 of the dedicated communication cable 21, the device-side connection terminal 223 is configured with four types of +5 V, + D, −D, and GND, and is connected to a regular standard connection terminal 911. On the other hand, + D and -D of the device side connection terminal 223a are interchanged. The device side connection terminal 223 forms a socket.

  The data control device 22 includes a plurality of first communication terminals 211 connected to the plurality of terminal side connection terminals 203, a plurality of second communication terminals 212 connected to the plurality of device side connection terminals 223, respectively. When a predetermined operation is received from the user, a data update control unit 224 that updates data in the device-side storage unit 221 to data in the terminal-side storage unit 201 is provided.

  Thereby, in spite of a simple configuration, it is possible to prevent outflow and falsification of data due to connection of a commercially available external terminal and to perform secure data update.

  That is, as shown in FIG. 4A, one of the plurality of communication terminals 911 of the commercially available communication cable 91 is connected to the plurality of terminal side connection terminals 203 of the commercially available external terminal 20, and the other plurality of communication terminals of the commercially available communication cable 91 are connected. When 912 is connected to each of the plurality of device side connection terminals 223 of the data control device 22, one of the plurality of communication terminals 911 is appropriately connected to the plurality of terminal side connection terminals 203, but the device side connection terminal 223 is A replacement portion 223 a is provided for the other plurality of communication terminals 912 of the commercial communication cable 91. Therefore, even if the data update control unit 224 tries to access the terminal-side storage unit 201 of the commercial external terminal 20 via the device-side connection terminal 223, the other communication terminal 912 and the device-side connection terminal of the commercial communication cable 91 are used. Since the connection with H.223 is not appropriate, the data update control unit 224 cannot read or write data to the terminal-side storage unit 201 of the commercially available external terminal 20.

  As a result, the manufacturer side introduces the data control device 22 (for example, a video playback device) to the operator, and connects the commercially available external terminal 20 owned by the operator and the manufacturer's data control device 11 with the commercially available communication cable 91. Even if an attempt is made, an appropriate connection cannot be made in the first place, so that the outflow and falsification of data due to the connection between the commercially available external terminal 20 and the data control device 22 can be reliably prevented.

  On the other hand, as shown in FIG. 4B, the first communication terminal 211 of the dedicated communication cable 21 is connected to each of the plurality of terminal side connection terminals 203 of the commercially available external terminal 20, and the second communication terminal 212 of the dedicated communication cable 21 is connected. When connected to a plurality of device side connection terminals 223 of the data control device 22, the replacement portion 223 a of the device side connection terminal 223 is equivalent to the replacement portion 212 a of the second communication terminal 212. Therefore, the connection between the second communication terminal 212 and the device side connection terminal 223 becomes appropriate, and the data update control unit 114 can perform data communication with the commercial external terminal 20 via the dedicated communication cable 21. Data can be read and written to the terminal storage unit 201. As a result, the data in the device-side storage unit 221 can be updated to the data in the terminal-side storage unit 201 by receiving a predetermined operation from the user.

  Even if the second communication terminal 212 of the dedicated communication cable 21 is connected to a connection terminal of a commercially available external terminal, the second communication terminal 212 has the replacement portion 212a, and thus an appropriate connection cannot be made. . Therefore, even if two commercially available external terminals are connected via the dedicated communication cable 21, data communication cannot be performed mutually. Even if the device-side connection terminal 223 of the data control device 22 is connected to a connection terminal of a commercially available external memory, the device-side connection terminal 223 similarly has a replacement portion 223a. Data communication with commercially available external memory is not possible.

  Thereby, even if the manufacturer introduces the data control device 22 and the dedicated communication cable 21 to the handler, the handler can update the data of the target data control device 11 only by using the dedicated communication cable 21. Since this is not possible, secure data update can be performed.

  Further, the second communication terminal 212 constitutes an exchange portion 212a for the other plurality of communication terminals 912 in the commercial communication cable 91 (even if the exchange portion 212a is constituted for one of the plurality of communication terminals 911). The other plurality of communication terminals 912 correspond to one of the plurality of communication terminals 911, and the device side connection terminal 223 is connected to the communication wiring 222 from the device side storage unit 221. Since the replacement part 223a only needs to be configured, the configuration is extremely simple and has an advantage of being relatively easy to implement.

  FIG. 5A shows a whole photograph of the dedicated communication cable of the second data update system according to the present invention, and FIG. 5B shows a male type and a female type of the dedicated communication cable of the second data update system according to the present invention. The photograph of the communication terminal is shown. As shown in FIG. 5A, the external appearance of the dedicated communication cable 21 is equivalent to a commercially available communication cable at first glance. Further, as shown in FIG. 5B, the external appearance of the male first communication terminal 211 and the female second communication terminal 212 of the dedicated communication cable 21 is equivalent to a commercially available communication cable.

  However, the first communication terminal 211 has an arrangement equivalent to the arrangement of one communication terminal in the commercial communication cable, and the second communication terminal 212 has two or more arrangements compared to the arrangement of the other communication terminal in the commercial communication cable. By configuring so that the communication terminals are replaced, it is possible to prevent data outflow and falsification due to connection of a commercially available external terminal and to perform secure data update. Moreover, since it is not different from a commercial communication cable in appearance, the operator can accept the carry-in of the dedicated communication cable 21 and the data control device 22 from the manufacturer without a sense of incongruity.

<Each component>
