Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bulletin board system for browsing a paper medium document using a computer,
The present invention relates to a bulletin board system suitable for digitizing and managing documents requiring information protection or extracting information on documents.

[0002]

2. Description of the Related Art When a resident record system changes in a resident record system in a local government, the change record list output from the resident record system is used to correctly reflect the resident change information in other business systems such as a nursing care insurance system. Circulate the list to other departments to see if it is correct and correct it. At that time, if you circulate the list of paper media, the list will be lost during circulation, and the distributor cannot know who is currently circulated, so it takes time to collect the list for reasons such as replacement of the list. . In addition, since personal information is described in the list, it is necessary to protect the authenticity and information of the list. In order to solve the above problems, a method of computerizing the list to prevent management and reorganization of documents and setting a usage right is suitable. This type of method creates a document as described in a bulletin board system of groupware, for example, Japanese Patent Laid-Open No. 2001-142874, and after the confirmation of the creator himself and the approval / examination of the document, the data is stored. There is a method of performing PDF format and encryption processing, and then registering so that the user can browse according to the usage authority.

[0003]

In the conventional system,
When the contents of the list are reflected in the business system, manual input is required, which is inconvenient and causes an input error. In addition, the viewer cannot easily understand which document posted on the bulletin board is subject to the title, and thus overlooks the document. Furthermore, even when everyone has finished browsing, the documents are still posted on the bulletin board, which is not suitable from the viewpoint of information protection.

[0004]

[Means for Solving the Problem] When distributing a list, the list prepared by the distributor is read by a scanner, and the distributor read from the IC card of the distributor and the viewer acquired from the bulletin board system server are converted into image data. Watermarking,
Register the created image file in the bulletin board system. A portion of information necessary for reflecting the business system of the image file designated by the distributor with the pen input device 7 or the like is encoded by OCR and added to the image data as non-display data. Also, it is determined whether or not the next list is the same as the format defined by the distributor, and if the format is the same, the previously encoded location is automatically encoded. This automates the process of encoding when there are a large number of lists.

When the viewer sees the bulletin board, the bulletin board system confirms whether the viewer read from the IC card and the viewer watermarked in the image file, which is a document, match, and highlights the matched document. When a viewer opens an image file, if the viewers match, the bulletin board system determines that the viewer can view it, displays the list image on the screen of the viewer terminal, and can extract the coded information. Put in a state. As a result, the information on the image file can be protected, and the viewer can grasp the necessary documents only by referring to the bulletin board. Next, when displaying the image data on the viewer terminal, the coded portion of the image is highlighted. The viewer checks the transfer information in the image file and uses the coded data when correcting the data. As a result, manual input is omitted, work processing is made more efficient, and input errors are prevented. When all the images are browsed by the viewer, the end of the browsing is watermarked in the browsed image file. When all viewers have finished browsing, the bulletin board system deletes the image file from the server and notifies the distributor. This ensures that documents aren't left on the bulletin board after everyone has viewed them. Also, since the image file itself has the information of the viewer / browser,
Even if the internal information of the bulletin board system is erased due to the failure of the bulletin board system, the viewer and the browsed information are retained.

Bulletin board system 1 configured as described above
2 will be described with reference to FIG. The bulletin board system is an IC card reader 6 of the IC card in which the name of the distributor is registered by the staff of the Citizen's Section who is in charge of the resident recording system who is the distributor of the transfer information list (FIGS. 10 and 11).
When inserted into the display, a distributor screen (FIG. 3) is displayed on the display of the distributor terminal. The name of the reader is acquired from the server 2 by the designation of the staff of the nursing care section in charge of the care insurance system, who is the viewer of the list, using the distributor's mouse or touch panel (21). After that, by selecting the image data button of the distributor, the list set in the image scanner is read and converted into image data (22).
The name of the distributor imported from the card and the name of the viewer acquired from the server are watermarked in the image file as digital watermarks (23) (24). Since there is one list for each transfer, if there are multiple lists, connect all the lists and create one image file that will be displayed on the viewer terminal as one page per page and watermark it. I do.

Next, the distributor screen (FIG. 4) is displayed on the display of the distributor terminal. When there are a plurality of lists, the image files are displayed page by page on the screen and the current number of pages is displayed. In a business system such as a long-term care insurance system where the information in the image file is different from the list in the case where the resident information is different, the distributor specifies the title portion of the information necessary to correct it, using the touch panel or pen input device 7. When the button is selected, the specified portion is extracted, coded by the OCR program and displayed on the screen (25). Here, by using a pen input device or the like, the file capacity is reduced by encoding only the necessary information from among many information on the image data. After that, when the distributor specifies the information to be reflected in the business system on the touch panel or the like and the coding button is selected, the specified part is extracted, coded by the OCR program and displayed on the screen (407), It is added as non-display data to the image file along with the current page number and name. Also, the position information of the portion specified by the pen input device 7 or the like is acquired and added to the image file (2
6). At that time, the portion coded by the added position information is highlighted. For example, when the distributor encodes the personal number on the first page, first, "personal number"
Circle (401) with the pen input device 7, and press the name button (40
If you select 2), the system will encode the "personal number" and display it on the screen (403). Next, when the distributor encloses the personal number data (404) with the pen input device 7 and selects the encoding button, the system encodes the personal number data, and the upper left portion and the lower right portion of the encoded portion are displayed. Acquire the location information of the part, "1", "personal number", "1234567890", "
A record "10-20.50-30""is added to the image file as hidden data. Further, the title of the data to be encoded can be directly input (403) using a keyboard. When the execute button is selected when the distributor encodes all the information necessary for correction, the document layout setting screen (FIG. 5) is displayed. On the document layout setting screen, image data other than the coded portion on the screen of FIG. 4 is extracted by the added position information. Part of individual data is pen input device 7 depending on distributor
When the delete button is selected, the image data in which the specified portion is omitted is displayed. After the layout is defined by the distributor, when the execute button is selected, the same part as the coded part on the screen of FIG. 4 is coded on all pages that match the defined layout (28). As a result, the distributor does not have to perform the encoding process of the plurality of lists having the same layout page by page, and can perform the process in a short time. Although the layout is the same, if another encoding process is desired, the corresponding list can be displayed by pressing the previous page and next page buttons on the screen of FIG. 4 and can be set individually. After that, when the distributor selects the registration button (406), the system registers the created image file and the non-display data added to the image file in the bulletin board system server (29).

[0016] When the viewer of the list inserts the IC card in which the name of the viewer is registered into the IC card reader 8 and accesses the bulletin board system at the viewer terminal (31), the bulletin board system displays the viewer terminal display. The viewer screen (FIG. 6) is displayed on. On the viewer screen, a plurality of documents registered in the server are displayed, and the name of the viewer captured from the IC card is transmitted to the server 2 (32) and the name of the viewer watermarked in the image file is displayed. If they match (3
3), highlight the post (34). Postings that do not match the name of the viewer imported from the IC card and the name of the viewer watermarked in the image file are not allowed to be viewed (35). Since the bulletin board is highlighted on the screen, the viewer can see the bulletin boards that can be viewed at a glance, and the necessary bulletin board can be overlooked. In addition, personal information is described in the list, and it is necessary to protect the information. Since it is confirmed whether the IC card reader matches the viewer watermarked on the screen, it is possible to regulate the viewer.

When the highlighted article is opened by the viewer, the viewer screen (FIG. 7) is displayed on the display of the viewer terminal. On the viewer screen, the image data of the list and the current page number are displayed, and the coded portion of the image file is highlighted by the added position information. As a result, the viewer can recognize the coded portion at a glance. The viewer confirms that the resident information of the business system and the data in the image match.
(36). If the transfer information is not correctly reflected in the resident information of the business system, the coded data can be used and corrected.

For example, when the address of the resident information in the business system is different, the viewer first extracts the personal number as a search key (37). The viewer clicks the name button (70
If you select 1), the system will extract from the hidden data attached to the image file by the page number currently displayed and display a list of the titles of the data coded on that page as a pop-up menu.
When the viewer selects a personal number from the list, the system displays "personal number" in the name on the screen (702) and "1234567890" in the data (706). The viewer compares the coded data with the image data, confirms that the coded data is correct, selects the extract button (703), and the system selects the coded personal number "1234".
567890 ”is extracted from the non-display data added to the image file and saved in the clipboard. The viewer can use the personal number by pasting it (38). This not only saves the trouble of directly entering the personal number, but also prevents an input error due to manual input. When correcting the address, the coded address can be extracted by performing the same operation for the address.

When the viewer confirms up to the last page of the image file and selects the end button (704), a read notice is sent to the server 2 (39), and the system displays that the viewer has viewed as an image file. Watermark (40). When watermarked information is watermarked to all viewers that are watermarked in the image file (41), the image file is deleted from the server (42) and the distributor terminal is notified of the end of browsing (43). As a result, it is possible to prevent the image files of the list requiring protection of the personal information from being left on the server. Further, the distributor can recognize that the list is viewed at the same time when it is viewed by all the viewers who have specified the viewing.

Since the information in the list is important data to be reflected in the business system, it is necessary to guarantee the authenticity of the image file. When the distributor button on the screen is selected, the watermarked distributor is displayed, so that the authenticity can be confirmed.

The distributor can change the posted items such as replacement of the posted items. When the distributor accesses the bulletin board system from the distributor terminal, the system transmits the name of the distributor of the IC card to the server 2 and highlights the name of the distributor as watermarked in the image file, highlighting the image. The file can be changed, and the distributor can replace or delete the posted item.

In this bulletin board system, since the posted matter itself has information such as a distributor, a viewer, and a viewer,
Even if the bulletin board system fails and the internal information of the bulletin board system is erased, the information about the bulletin board is retained, and the information up to now can be inherited simply by registering the bulletin board on the bulletin board system that has been repaired or newly constructed. It can be distributed and viewed.

[0023]

As described above, according to the present invention,
In the bulletin board system, image data that can be viewed by the viewer is highlighted, so that the viewer can grasp the necessary documents only by referring to the bulletin board. In addition, since the information required by the viewer is coded, manual input can be omitted, operational processing can be made more efficient, and input errors can be prevented. On the other hand, when the list is large, the distributor has less trouble in the coding process because the coding is automated from the layout of the list. In addition, it is possible to protect the information because it is determined that the image data can be viewed by the viewer, and the document is not left on the bulletin board after all the users have viewed. further,
By providing the document itself with the information of the viewer / browsing end, even if the internal information of the bulletin board system is erased due to the failure of the bulletin board system, the information of the viewer and the browsed information is retained.
