<< Embodiment 1 >>

<Overview>
FIG. 1 is a conceptual diagram for explaining an outline of a transaction using the barcode display device of the present embodiment. As shown in the figure, the “bar code display device” 0101 displays the bar code and the change display (moving image display in which the sun and waves are moving) on the same screen based on the display change information. It is equipped with the feature to output. By providing the feature, it becomes easy for a person who receives the barcode presentation to confirm that the barcode is not illegally copied.

  In the present embodiment, the information carrier to be displayed and output is described as a barcode. However, the information carrier to be output or read is not limited to a barcode, for example, a two-dimensional code such as a QR code (registered trademark), Of course, it may be information encoded with the sequence information of the dye (the same applies throughout the present specification).

<Functional configuration>
FIG. 2 is a diagram illustrating an example of functional blocks of the barcode display device according to the present embodiment. As shown in this figure, the “barcode display device” 0200 of this embodiment includes a “barcode information acquisition unit” 0201, an “output display change information acquisition unit” 0202, and a “display output unit” 0203. Have. Specifically, it is conceivable that the barcode display device is realized by a mobile terminal such as a mobile phone or a smartphone.

  The functional blocks of the bar code display device described below can be realized as hardware, software, or both hardware and software. Specifically, if a computer is used, a CPU, a main memory, a GPU, an image memory, a graphic board, a bus, or a secondary storage device (a storage medium such as a hard disk, a nonvolatile memory, a CD, a DVD, and the like) Media reading drive), input devices used for information input, touch panels, cameras, microphones, speakers, scanner devices such as bar code readers, display devices such as liquid crystal or organic EL displays, and other external peripheral devices A hardware configuration unit, an interface for the external peripheral device, a communication interface, a driver program for controlling the hardware, and other application programs are listed. Then, by the arithmetic processing of the CPU in accordance with the program developed on the main memory, the data input from the input device or other interface etc. and held in the memory or hardware is processed and accumulated, or each of the hardware And commands for controlling the software are generated. Here, the program may be realized as a plurality of modularized programs, or may be realized as a single program by combining two or more programs.

  The barcode display device of the present invention can also be realized as a system by combining with one or a plurality of devices. A part of such an apparatus can be configured as software. Further, a storage medium in which such software is recorded is naturally included in the technical scope of the present invention (the same applies throughout the present specification, not limited to the present embodiment).

  The “barcode information acquisition unit” 0201 is configured to acquire barcode information that is information for displaying a barcode. The “information for displaying a barcode” is not only specific barcode image information but also information for generating a barcode image for reading by a function or program for generating a barcode image. Sometimes. Specifically, acquiring image information of a barcode composed of a black bar and a white bar, or acquiring numbers, characters and / or symbols for arranging black or white bars as barcode information Can be considered. As an acquisition mode, it is conceivable to acquire from an external server holding barcode information via a network, and more specifically, a black bar portion constituting or constituting a barcode Information on the combination with the white bar portion and the width of each portion is acquired.

  The “output display change information acquisition unit” 0202 is configured to acquire display change information that is information for outputting a change display that is a display that changes color, shape, pattern, or a combination thereof over time. The As an example of “display that changes over time”, “information for outputting a change display” is not only specific video information but also read by a function or program for generating a video. It may be information for generating a moving image for As a specific acquisition mode of the display change information, a configuration in which the display change information is acquired via a network from the barcode server apparatus or other external apparatus mentioned above can be considered.

  It should be noted that the playback speed of the moving image, which is the change display here, needs to be a speed at which a viewer of the moving image can recognize the change with time of the display. By adopting such a configuration, when the reader of the barcode receives the display screen, the change display changes over time, so that the display is illegally copied by a third party's photography or the like. It can be confirmed that it is not. In addition, it is possible for a person who intends to illegally use a barcode to clearly recognize changes in the display screen and to recognize that it is difficult to capture the screen as a still image and exploit it. .

  FIG. 3 is shown here. The figure is an example of the change display output based on the display change information acquired by the display change information acquisition unit. In this example, the change display is specific moving image information. This figure shows an example of display when a plurality of types of patterns in the display screen change over time, and (t-2) through (t-) are shown in order from (t-1) showing the flow of time. The pattern changes until 4), and after the display corresponding to (t-4), the display corresponding to (t-1) is performed again. As in this example, it is possible to perform so-called gradation display by acquiring information for performing display such that the pattern changes over time, and the change display is output to a display output unit described later together with a barcode. As a result, the person who viewed the output destination screen may make it difficult or impossible to divert or misuse the barcode displayed on the screen even if the screen is shot with a still camera. It becomes possible.

  Note that the display content of the display change information does not need to be uniquely associated with the barcode. For example, different display change information is obtained for each barcode usage target (for example, payment payee store, fee payment company). In addition, it can be considered that the change display for each use target can be performed. Display change information that differs for each usage target can be obtained in association with a barcode. Specifically, the CI (corporate identity) of the store or company that is the usage target and the video display of the name are given as examples. (The association between the barcode and the display change information will be described in detail in the second embodiment). In this case, by adopting the configuration, it can be easily recognized that the change display is properly displayed in the store or the like to be used.

  The “display output unit” 0203 is configured to output a barcode based on the acquired barcode information and a change display based on the acquired display change information on the same screen. Specifically, it is realized on a display of a mobile terminal such as a smartphone or a mobile phone. As a specific mode of output, a layer process for superimposing a barcode image frame on a frame on which a change display is made is performed and displayed. Configuration is conceivable. Here, “output on the same screen” means that a barcode and a change display are output simultaneously.

  “Output a barcode based on barcode information” means outputting a barcode image which is barcode information or outputting a barcode image expressed using the barcode information. In addition, outputting “change display based on display change information” means outputting a moving image that is display change information or outputting a moving image expressed using the display change information. .

  Note that the change over time of the moving image that is the change display may be synchronized with the time. In that case, the barcode reader can read the barcode and also read the moving image that is the change display, and can determine the authenticity of the change display. Specifically, information indicating a change over time of a moving image that is a change display is acquired in advance on the barcode reader side, and the authenticity of the moving image that is a change display read based on the information is determined.

  In the case of the example described with reference to FIG. 3 with respect to an example of synchronizing the temporal change of the moving image with the time, it corresponds to (t-1) to (t-4) from 01 seconds to 04 seconds per hour. It is conceivable that the change display to be performed is performed in units of seconds, and the output is performed at a speed such that the change display corresponding to (t-1) is performed again in 05 seconds.

  Note that the synchronization processing of the time measured in the barcode display device, which is a reference for changing the moving image over time, and the standard time is the timing when the barcode display device is turned on, the base station or the sector associated with the movement. It can be considered to be performed at the timing of the hangover between. By adopting such a configuration, it is possible to make it difficult for an error to occur in the change mode of change display over time, and to improve the accuracy of the moving image reading process in the barcode reader.

  In addition, the specific aspect of the display output of a change display and a barcode is not limited to the example demonstrated so far. In any case, even if the display screen is duplicated by a still camera by taking a configuration that outputs the barcode together with the moving image, the duplicated image is a still image, and the display screen is displayed to a third party who has seen it. It is possible to immediately recognize that the data has been copied, and to prevent unauthorized use of the copied barcode.

<< Embodiment 3 >>

<Overview>
Each of the barcode server devices of the present embodiment holds the barcode information and the display change information in association with each other, and outputs the associated barcode information and the display change information to the barcode display device. As prepared. As in the first embodiment, it is possible to adopt a configuration in which code information for displaying a two-dimensional code instead of a barcode is held and output to a display device.

<Functional configuration>
FIG. 6 is a diagram illustrating an example of functional blocks of the barcode server device according to the present embodiment. As shown in this figure, the “barcode server device” 0600 of this embodiment includes an “association holding unit” 0601 and an “output unit” 0602.

  The functional blocks of the barcode server apparatus described below can also be realized as hardware, software, or both hardware and software, as in the barcode display apparatus described in the first embodiment. Specifically, if a computer is used, a CPU, a main memory, a GPU, an image memory, a graphic board, a bus, or a secondary storage device (a storage medium such as a hard disk, a nonvolatile memory, a CD, a DVD, and the like) Media reading drive), input devices used for information input, touch panel, printers, scanner devices such as barcode readers, and other hardware components such as external peripheral devices, and interfaces and communications for the external peripheral devices Interface, a driver program for controlling the hardware, and other application programs. Then, by the arithmetic processing of the CPU in accordance with the program developed on the main memory, the data input from the input device or other interface etc. and held in the memory or hardware is processed and accumulated, or each of the hardware And commands for controlling the software are generated. Here, the program may be realized as a plurality of modularized programs, or may be realized as a single program by combining two or more programs.

  The “association holding unit” 0601 is information for outputting barcode information that is information for displaying a barcode and a change display that is a display that changes color, shape, pattern, or a combination thereof over time. The display change information is associated and held. The bar code information and the display change information here are the same information as the information described in the first embodiment.

  The “output unit” 0602 is configured to output the associated barcode information and display change information to the barcode display device. As a specific output mode, a configuration in which the barcode information and the display change information are output at the same timing is conceivable, but a configuration in which only one of them is output first may be employed. For example, the display change information is output first, and the transmission is performed in response to a request transmitted later together with an ID indicating the display change information or an ID indicating an association between the display change information and the barcode from the barcode display device. A configuration is conceivable in which the barcode information associated with the display change information is specified and the specified barcode information is transmitted. With this configuration, it is possible to keep the bar code information from being transmitted to the bar code display device until immediately before using the bar code, thereby reducing the chance of unauthorized use of the bar code information.

  Here, a second output unit that outputs the display change information to the barcode reader may be further provided. Specifically, the barcode is associated with the barcode in response to a request to transmit the display change information transmitted together with the barcode and the ID indicating the barcode from the barcode reading device that has read the barcode. Display change information is output. By adopting this configuration, the barcode reader can also recognize the change over time of the change display based on the display change information. Therefore, when reading the barcode, It is possible to determine the appropriateness of the transaction in consideration of the appropriateness of the displayed change display.

In the case of information other than the change display, the content of the change display such as, for example, a display theme that changes with time (for example, “Sun and Wave” shown in FIG. It may be information that can be recognized.

  In the barcode reading apparatus, when the change display itself is not acquired as the display change recognition information, a change display reading unit that reads the change display may be provided. Specifically, it is conceivable to read a change display displayed using a reading device such as a scanner for a predetermined time. For example, when the change display information described with reference to FIG. ) To (t-4), the reading process is preferably performed continuously.

  When the change display is read by the change display reading unit, it is confirmed whether or not the read change display and the change display recognition information are associated with each other. As an example of confirmation, for example, it is conceivable to check the color, shape, pattern, or combination thereof in the change display with the color held as the change display recognition information. The collation result is output as appropriate. For example, by displaying on a display device such as a display of a barcode reader, the user can visually recognize the collation result and determine whether the change display is appropriate. Can be urged. In addition, it is possible to determine the appropriateness of the change display used for verification by providing a determination unit for making the determination in the barcode reader and using the determination unit as the output destination of the verification result. In the determination unit, for example, a change over time of the change display that is a moving image is acquired for a predetermined time, and the degree of coincidence with the change display held in advance is determined. By adopting such a configuration, not only when the barcode display screen is duplicated as a still image, but also when the barcode display screen is duplicated as a moving image, the change display displayed with the barcode is displayed. Since it is possible to confirm the appropriateness, unauthorized use of the barcode can be prevented in advance.
