Description

This invention relates to data processing apparatus and program.

Generally, in order to prove that the issued form is a valid base paper, a background pattern is printed on the form sheet, but each item data printed in the form is printed with special characters. Other than that, it could not be easily discovered even if it was tampered with. Therefore, conventionally, a form image is converted into a two-dimensional code, and the form is issued by printing the two-dimensional code in the form, and the two-dimensional code is read from the form and reproduced and displayed on the form image. Therefore, a technique that enables tampering check by visual verification is known (see Patent Document 1).

The image scanner 23 is provided with a hopper unit 23A having an automatic paper feeding function into which the collected tickets are inserted, and the ticket automatically fed from the hopper unit 23A is conveyed to the installation position of the image scanner 23. Then, the image scanner 23 operates to read the entire image of the ticket ticket surface and perform image processing. Note that the memory 24, the key operation unit 25, and the display unit 26 are basically the same as the memory 13, the key operation unit 14, and the display unit 15 on the ticket issuing device 1 described above, and thus description thereof is omitted. .

FIG. 2 is a diagram showing a print example of a concert ticket issued from the ticket issuing device 1.
When the ticket issuing apparatus 1 prints and issues this concert ticket, it reads out the concert ticket print form from the ticket database CDB, and issues and arranges each item data in accordance with this print form to issue the concert ticket. This concert ticket is pre-printed with the title name and date of the event fixed, as well as a “venue name” and “designated seat number” as items unique to this ticket. Each item of “designated seat number” is a print item that is read out from the ticket database CDB and printed out when the ticket is issued. Following this print item, “name”, “address”, and “purchase method” are provided as other items, and each of the “name”, “address”, and “purchase method” items is the customer who uses the ticket. Is a description item for handwriting arbitrary contents.

A two-dimensional code (QR code in the illustrated example) is pattern-printed in a blank portion of the concert ticket, for example, a blank portion in the lower right portion in the figure. In this two-dimensional code pattern, each item “venue name”, “designated seat number”, “name”, “address”, “purchase method” of the concert ticket has its “range” and “processing type”. , "Value" data is incorporated.
FIG. 3 is a diagram for explaining “processing type”, “range”, and “value” incorporated in the two-dimensional code pattern. The “range” and “processing type” are instruction information (instruction information) for instructing the printing items “venue name” and “designated seat number” as processing targets and also instructing the processing type.

  The above-mentioned “range” is information indicating the position and size of the instruction item. Each item on the ticket forms a rectangle, and the position of the instruction item is determined by the upper left and lower right coordinates of the rectangular area. The size of the area is determined. Note that the upper left coordinates and lower right coordinates of this area are, for example, XY coordinate values when the upper left corner of the concert ticket is the origin of the plane coordinate system. “Process type” includes a process for checking whether or not the data of the instruction item has been falsified as shown in the figure, and a process for saving the data in the instruction item. "," 2: Save ", the desired processing type is selected.

  “Value” is item data arranged and printed in the print item when the processing type is “1: falsification check”, for example, item data “Yokohama ...” printed on “Venue name” “Designated seat” In the case where the item data “SS seat 1F1 column 22” is printed in “No.” and the processing type is “2: Save”, the “name”, “address”, “purchase method” that are the respective description items. The item name of becomes “value”. Note that the ticket database CDB includes, for example, a print form, item data corresponding to “venue name” and “designated seat number”, and item names of “name”, “address”, and “purchase method” that are each description item. The entry data entered in each description item and the storage destination address (image file number) of the two-dimensional code pattern are stored and managed, but the stored contents differ depending on the type of ticket.

  The data processing apparatus 2 reads the entire ticket surface by the image scanner 23 while conveying the concert ticket group put into the hopper 23A one by one to the image scanner 23 side, and the two-dimensional code pattern is included in the ticket. Is printed while scanning this two-dimensional code pattern, and the processing type is checked for each item based on the decoding result, whether it is “tamper check” or “save”. The tampering check process or the storage process is executed according to the processing type. In this case, the falsification check process is executed for each print item in the ticket, and the item data storage process is executed for each description item.

  This “tampering check process” determines whether a ticket is authentic by checking whether the item data printed in correspondence with each print item on the ticket has been tampered with, and is included in the two-dimensional code. The "value" is used as comparison reference data at the tampering check, and the result of character recognition of this "value" is compared with the result of character recognition of the print data in the image data. Whether or not the print data has been tampered with. In addition, the “item data storage process” recognizes characters for each entry data item arbitrarily entered in each description item included in the image data, and stores and saves the recognition result in the ticket database CDB or the like. It is processing of.

  Next, the operation concept of the ticket issuing device 1 and the data processing device 2 in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

FIG. 4 is a flowchart showing the operation when the ticket issuing device 1 inputs and creates ticket print data.
First, in the ticket issuing apparatus 1, the CPU 11 reads out a print form from the ticket database CDB and displays it (step A1), and when an arbitrary item position in the ticket screen is designated by the cursor (step A1). In step A2), the upper left coordinates and lower right coordinates of the designated item are fetched as “range” data for specifying the area to be processed and temporarily stored in the memory 13 (step A3). Next, a processing type menu is displayed in a window, and when an arbitrary “processing type” is selected and designated (step A4), the processing type is fetched and temporarily stored in the memory 13 (step A5).

  In this case, the selected processing type is discriminated (step A6). If “1: Tampering check” is selected, a message prompting key input of the check contents is displayed and output (step A7). The item data input in response is taken in as “value” data and temporarily stored in the memory 13 (step A8). If “2: Save” is selected as the processing type, a message prompting the user to input an item name is displayed and output (step A9), and the item name input in response thereto is set to “value”. Is temporarily stored in the memory 13 (step A10). When the input for one item is completed in this way, a process of dividing the “range”, “process type”, and “value” temporarily stored in the memory 13 with commas is performed (step A11).

  The CPU 11 checks whether or not the user has instructed the end of input for one ticket (step A12), returns to step A2 until the end of input is instructed, and repeats the above operation for each item. As a result, when the input for all items is completed, the contents of the temporary storage are sequentially read out from the memory 13 for each item, and the “range”, “processing type”, and “value” for each item are two-dimensional code. (QR code) is converted into a pattern (step A13), and this two-dimensional code pattern is stored and saved as an image file (step A14), and the "value" of each item is stored and saved in the database CDB (step A14). A15). When the two-dimensional code pattern is saved as an image file, the contents of the database CDB and the image file are linked by storing the image file number in the database CDB.

As a result, when the input for one ticket is completed, the process proceeds to the next step A16, where it is checked whether the user has instructed the input end for all tickets, and the same operation is repeated until the completion of all tickets.
In the above-described print data input creation process, when “2: Save” is selected as the process type, a message prompting the user to enter an item name is displayed and output, and the item name is changed in response. Although it is input as “value” data, when the item name is fixedly set in the print form, the item name may be read from the print form when the two-dimensional code is generated. .

FIG. 5 is a flowchart showing an operation when the ticket issuing device 1 prints and issues a ticket.
First, the ticket issuing device 1 reads out a print form from the ticket database CDB (step B1), reads out print data for one ticket (step B2), and further, a two-dimensional code pattern associated with the print data. Is read (step B3), and data is arranged and printed in each item in accordance with the print form (step B4). Then, the two-dimensional code pattern is printed in a predetermined unprinted area (for example, the lower right blank area) (step B5), and the ticket is discharged from the printing unit 16 and issued (step B6). Then, it is checked whether or not there is a next print target ticket in the ticket database CDB (step B7). If there is a next print target ticket, the process returns to step B2, and the above-described operation is repeated.

FIG. 6 is a flowchart showing the overall operation of the data processing apparatus 2.
First, the CPU 21 of the data processing device 2 determines that one ticket has been supplied to the position of the image scanner 23 in a state where a ticket is inserted in the hopper unit 23A with an automatic paper feeding function. If not detected (YES in step C1), the image scanner 23 is driven to read the entire image of the ticket (step C2). Then, it is checked whether or not the two-dimensional code pattern is included while scanning the entire ticket image for the vertical resolution and the horizontal resolution (step C3). In this case, since the symbol figures are incorporated in the three corners constituting the two-dimensional code pattern, whether or not the two-dimensional code pattern is included by detecting these symbol figures and their positional relationship. To check.

  If the two-dimensional code pattern is not included in the ticket (NO in step C3), the process returns to the first step C1 and waits for the next ticket, but if the two-dimensional code pattern is included, The CPU 21 decodes all the contents of the two-dimensional code pattern (step C4). In this case, corresponding to each print item “venue name”, “designated seat number” and each entry item “name”, “address”, “purchase method” in the concert ticket, its “range”, “processing type” , “Value” are decoded respectively.

  Next, as a result of decoding each “range”, the position of the corresponding item area (rectangular area) and the size of the area are specified based on the upper left coordinates and lower right coordinates (step C5). Any one item is designated from each item position (step C6). In this case, an item closest to the upper left corner of the ticket (the origin of the plane coordinate system), for example, the “venue name” of the print item is designated as the first item. Next, item data (image data) printed in the designated item “venue name” is cut out (step C7), and character recognition is performed (step C8).

  Next, the CPU 21 determines whether the “processing type” corresponding to the designated item is “1: falsification check” or “2: save” (step C9). Now, since the designated item is “venue name” and its “processing type” is “1: falsification check”, the decoding result of “value” corresponding to the designated item is compared with the character recognition result (step C10). ), It is checked whether or not they match (step C11). That is, the decoding result of “value” is compared with the character recognition result of the designated item as comparison reference data at the time of falsification check. As a result, if a mismatch is detected, the print data of the designated item is altered. As a result, an alarm message is displayed and output from the display unit 26 and the alarm notification unit 27 is driven to generate and output an alarm sound (step C12). If the two match, the next item is designated. (Step C13), the presence / absence of the designated item is checked (Step C14).

  In this way, it is checked whether or not all items have been specified. Since the process for the first item has been completed, the next print item “designated seat number” is designated, and then the process returns to step C6 to Repeat the same operation. As a result, if the print data has not been falsified, the next third item is designated (step C13). Since the third item is the “name” of the description item, and the “processing type” is “2: save”, the process proceeds to the next step C15, and the item data (character recognition) of the description item “name” The result is stored and saved in a ticket data memory (not shown) in the storage unit 22. Then, the process proceeds to step C13, and since the fourth and fifth items “address” and “purchase method” are also described items, the item data (character recognition result) is stored in the ticket data memory in the storage unit 22. Saved (step C15). Thus, when the processing for all items is completed (NO in step C14), the process returns to the first step C1.

  As described above, in this first embodiment, the ticket issuing apparatus 1 instructs the item as a processing target corresponding to an arbitrary item in the print form, and indicates the instruction information (instruction information) indicating the processing type. When creating and converting to a two-dimensional code, and arranging and printing each item data according to the print form and issuing a ticket, the two-dimensional code pattern is printed on the ticket, and the data processing device 2 The image data is read from the ticket with the code, the two-dimensional code is analyzed, the instruction item to be processed and the processing type are specified from the analysis result, and if the processing type is “1: tamper check”, the instruction item To check whether or not the print data has been falsified, and if the process type is “2: Save”, the data entered in the instruction item is stored and saved It is so arranged to perform a that process, it becomes highly versatile.

  In other words, instructions can be expressed in the two-dimensional code, and even if the print form is changed, the instruction information in the two-dimensional code need only be changed without changing the processing program. On the other hand, falsification check processing and data storage processing can be executed, and it becomes highly versatile. In this case, since the tampering check of the print data can be performed for each item in the ticket, the check can be surely performed as a whole, which is effective for determining the authenticity of the ticket. Further, since the item data can be stored for each customer entry item of the ticket, various types of information can be automatically collected, and the information can be collected reliably and efficiently.

In the first embodiment described above, the print data alteration check process or the storage process of the item data entered by the customer is executed according to the processing type in the two-dimensional code. For example, a data writing process or the like may be executed. In the first embodiment described above, the contents of the two-dimensional code are separated by commas. However, any delimiter may be used and applied to a concert ticket. However, discount tickets, coupon tickets, services The same applies to tickets.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIG.
In the first embodiment described above, the falsification check process is executed on the data processing apparatus 2 side after the ticket is issued. In the second embodiment, the contents of the ticket database CDB are falsified at the time of ticket printing. The ticket issuing device 1 checks whether it has been done.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 7 is a flowchart showing the operation when the ticket issuing device 1 according to the second embodiment prints and issues a ticket.
First, the ticket issuing device 1 reads out print data for one ticket together with a print form from the ticket database CDB (step D1) (step D2), and further reads a two-dimensional code pattern associated with the print data. After that (step D3), the two-dimensional code pattern is decoded (step D4), and the processing type in the decoding result is referred to to check whether or not it is “1: tampering check” (step D5). . As a result, if data is stored, the process proceeds to step D11. If tampering is checked, each print item in the decoding result, that is, “value” corresponding to “venue name” and “designated seat number”, and ticket database. The print data of “venue name” and “designated seat number” read from the CDB are respectively compared (step D6), and it is checked whether any one of them does not match (step D7).

  As a result, if there is a discrepancy item, the display unit 26 displays and outputs an alarm message on the assumption that the contents of the ticket database CDB corresponding to this ticket have been tampered with, and the alarm notification unit 27 is driven to generate and output an alarm sound. (Step D8), the process proceeds to Step D11. If all items match, that is, if the contents of the ticket database CDB have not been falsified (NO in Step D7), the print form is displayed. In addition, data is arranged and printed in each item, and a two-dimensional code pattern is printed in a predetermined unprinted area (for example, a blank area at the lower right) (step D9), and the ticket is discharged from the printing unit 16 Issue (step D10). Then, it is checked whether or not there is a next print target ticket in the ticket database CDB (step D11). If there is a next print target ticket, the process returns to step D2, and the above operation is repeated thereafter.

  As described above, the ticket issuing apparatus 1 of the second embodiment analyzes the ticket-corresponding two-dimensional code pattern when issuing the ticket by arranging and printing each item data in accordance with the print form, Since the contents of the ticket database CDB are checked based on the analysis result, the same effect as that of the first embodiment described above can be obtained, and the tampering check can be performed during data printing. It becomes possible to increase safety.

  In the second embodiment described above, the result of decoding the two-dimensional code pattern is compared with the data read from the ticket database CDB. However, the comparison is not limited to the text code, but the EMF (Enhanced MetaFile) format. The data may be converted and compared, and RAW data after print driver processing may be checked.

  In each of the above-described embodiments, the case where a “concert ticket” is illustrated as a printed matter is shown, but it can be similarly applied to discount tickets, coupon tickets, service tickets, and the like, as shown in FIG. It may be applied to “user registration postcards”. This “user registration postcard” has “purchased model name” and “serial number” as print items, and “name”, “address”, and “product impression” as described items. This “user registration postcard” A two-dimensional code pattern including “range”, “processing type”, and “value” corresponding to each item is printed at a predetermined position of “user registration postcard”.
