Description

  The present invention relates to an electronic document.

  Today, electronic documents such as PDF documents and Word (registered trademark) documents are distributed as information transmission means via various networks. Depending on the content of the information, there are those that are required to maintain confidentiality and those that are leaked. As one of the measures for satisfying the requirement, a conventional electronic document has a document browsing protection function using a password. However, the document browsing protection function is not always sufficient.

  FIG. 12A is a schematic diagram of a conventional network example for distributing an electronic document having a document browsing protection function. First, the same electronic document 2 whose distribution destination cannot be specified is sent from the transmission source to each company such as Company A and Company B. Here, for example, company C, which is a third party, can obtain electronic document 2 from company A or company B, but since the sender has no history of sending to company C, it is not known whether company C has obtained it. . Moreover, even if it is known, it is not always clear where the company C obtained from. Similarly, when a competitor obtains a document, it is difficult to determine where the document was sent from among third parties such as Company A, Company B, or Company C.

  FIG. 12 (2) is a schematic diagram of a network example in which the above-described prior art is improved. In this network example, a transmission source creates a document that can specify a distribution destination for each distribution destination and distributes the document to each distribution destination. The document that can specify the distribution destination is a document that has a watermark or a password set for each distribution destination. In this case, the distribution company A is bound by an agreement rule that it is not distributed to the third party C. Company C must separately request a document from the sender, and if the request is distributed to company C, the sender creates a document for company C.

  In the example of FIG. 12 (2), since the sender must create a document for each distribution destination, the burden of document creation increases. In addition, when a new distribution destination, for example, Company C wants to receive document distribution, it takes a considerable time until Company C obtains the document. Furthermore, when a competitor company illegally obtains a source document, the destination can be specified, but the competitor company can easily view the document contents.

In the invention of Patent Document 1, authentication for security is performed by a server via a network. Authentication is performed by application software. The invention of Patent Document 2 performs ID and password authentication with application software. The document is scrambled. The invention of Patent Document 3 performs authentication with a server by mail. ID and password authentication is performed by application software.

  It is an object of the present invention to create an electronic document that maintains confidentiality and avoids leakage when distributed using a network or the like.

The present invention has been made to achieve the above object. The electronic document according to the present invention is:
An electronic document displayed on a display device attached to a computer,
Computer
Setting means for providing a collation data input field on a predetermined page on the document that is opened and shown by an instruction to open the document from the input means;
A determination means for determining whether or not the collation data input in the collation data input field satisfies a predetermined condition; and
After the document is opened, as the specific part display means for displaying only the specific part of the document on the display device when the determination means determines that the input collation data satisfies the predetermined condition,
It is made to function.

An electronic document display method according to the present invention includes:
A method of displaying an electronic document on a display device attached to a computer,
In response to a command to open the document from the input means, the collation data is acquired via a collation data input field provided on a predetermined page on the document that is opened and shown,
It is determined whether the acquired collation data satisfies a predetermined condition, and when it is determined that the predetermined condition is satisfied, a specific portion of the document is displayed on the display device.

  If the electronic document according to the present invention is used, even if the electronic document is distributed to many distribution destinations using a network or the like, confidentiality is appropriately maintained and leakage is prevented. Less preparation work for distribution. Also, even if a leak occurs, the leak path can be easily identified.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments according to the present invention will be described below with reference to the drawings.

<< Outline of Application Examples of the Present Invention >>
FIG. 1 is a schematic diagram of a network example that realizes distribution of an electronic document according to the present invention. First, an outline of an application example of the present invention will be shown using this figure.

  The electronic document according to the present invention is programmed as described later so that the contents cannot be confirmed unless an ID and a password given separately are inputted. In the electronic document, when an ID and a password are input, the ID is displayed on the document. This identifies the ID that opened the document. There is only one electronic document created by the sender. The transmission source separately provides individual IDs and passwords to each distribution destination.

  In the network shown in FIG. 1, the company A can confirm the document contents by inputting the ID and password given to the company A into the distributed electronic document. At this time, the input ID is displayed on all the pages on the document, so that it can be specified that the document is opened with the ID for company A.

  The distribution destination can redistribute the document to a third party. For example, company A may redistribute documents to company C. However, the company C can request the ID and password for the company C separately from the sender, and can confirm the document contents by obtaining this. From the point of view of the sender, it is not necessary to create an electronic document for company C, and only an ID and password for company C need be provided.

  Even if a competitor obtains an electronic document, the document contents cannot be confirmed without an ID and a password. Even if the competitor obtains the ID and password, the leakage source can be specified. For example, even if the ID and password of Company B are obtained, the ID of Company B is displayed on the document, so that it can be confirmed that Company B has leaked the ID and password to the competitor.

<< First Embodiment >>
FIG. 2 is a block diagram (FIG. 2 (2)) of an electronic document display apparatus according to the present invention (FIG. 2 (1)) and an electronic document display device. The electronic document display device 10 is constructed by mounting electronic document display software on a general personal computer. In this specification, a PDF (Portable Document Format) document developed by Adobe Systems is taken as an electronic document. Of course, other electronic documents may be used. Here, the electronic document according to the present invention is preferably provided with a script function for an object, such as a PDF document. The PDF document taken up in this specification has a Java script function. As is well known, Java (registered trademark) is one of computer languages.

  The electronic document display apparatus 10 shown in FIG. 2B includes a document management unit 12, and the document management unit 12 includes a document display unit 14, a Java script execution unit 16, and a form control unit 18. The Java script execution unit 16 executes Java scripts for various objects included in the PDF document. The firmware control unit 18 receives the form control command issued by the Java script execution of the Java script execution unit 16 and controls various forms. This “form” is an object in the PDF document.

  The PDF document 20 shown in FIG. 2 (1) includes document data 22. The document data 22 includes an outline, document contents 38, various forms 26, and an execution Java script 24 at the time of saving. The document content 38 is the actual document content. Forms 26 include a password form 28, an ID form 30, a content form 32, a shadow form 34, and a watermark form 36. The various forms 26 are objects, and therefore include corresponding Java scripts.

  In a conventional electronic document, when attempting to open a document, first, input of a verification symbol such as a password is required, and the electronic document is opened only when a correct verification symbol unique to the electronic document is input there. In the present invention, when an operation for opening an electronic document is performed on a personal computer, the document itself is first opened. An ID form 30 and a password form 28 (described below) are attached to the first page, and prompts for input of an ID and a password. In other words, in the present invention, the input of the verification symbol is required immediately after the document itself is opened. Of course, the electronic document according to the present invention can be used together with the collation check function immediately before the document is opened by the collation symbol in the conventional electronic document.

  The ID form 30 is an editable text form for inputting an ID, and is generally attached to the first page of a document. The password form 28 is an editable text form for entering a password, and is generally attached to the first page of the document. 3A and 3B show schematic display examples of the ID form 30 and the password form 28. FIG.

  The shadow form 34 is a sheet-like non-transparent non-editable text form that covers the whole or part of the document content, and is displayed when a correct password for the ID is not entered. . The shadow form 34 is arranged for each page after the second page of the document. The watermark form 36 is a non-editable text form that sets and displays an input ID, and is not displayed when a correct password for the ID is not input. The watermark form 36 is arranged for each page after the second page of the document. Furthermore, the content form 32 is a non-editable text form that displays unique contents (for example, a document), and is not displayed when the correct password for the ID is not input. The content form 32 is arranged for each page after the second page of the document. 3 (1) and 3 (2) show a schematic display example (non-display example) of the shadow form 34. FIG. 6 (1) and 6 (2) show schematic non-display examples (display examples) of the watermark form 36 and the content form 32. FIG. The “watermark” here is a so-called “watermark”.

  The PDF document according to the first embodiment executes a Java script program embedded in a document when an ID and a password are input in each form, and stores ID and password information stored in the document. Compare the contents of the entered ID form with the contents of the password form.

  For example, by executing the code shown in Table 1 below, when “aaa@aaa.com” is input as the ID and “aaa” is input as the password, it can be determined that the ID and the password match. That is, when “aaa@aaa.com” is entered for the ID and “aaa” is entered for the password form, the shadow form is hidden and the contents of the ID form are set in the displayed watermark form. FIG. 4 is a flowchart of the processing of the contents of Table 1 below. FIG. 3 shows how the watermark form display and the shadow form non-display are realized by appropriate input of the ID and password (Pwd). It can be understood that the concealed content becomes clear only after the shadow form is hidden from display. FIG. 6 shows how the watermark form display and the content form display are realized.

  The electronic document including the code shown in Table 1 functions effectively when the number of IDs (and passwords) is fixed. In other words, the above code must be changed when a new ID (and password) is generated. In addition, the document size increases as the ID increases.

  Therefore, the PDF document according to the first embodiment authenticates that there is an input of a correct password that should correspond to the input ID by an authentication procedure different from Table 1 (ie, FIG. 4). Also good. That is, for example, when an ID and password are entered, the Java script program embedded in the password form inside the document is executed to calculate the password value from the content of the ID form, and the password value matches the content of the password form. You may make it determine whether to do.

  FIG. 5 is a flowchart including a part for calculating a password value from the content of the ID form and determining whether the password value matches the content of the password form. The “oText”, that is, the password value here is a numerical sum of the character codes for each character entered in the ID form. The codes are shown in Table 2 below.

  For example, according to the code in Table 2 below, if “aaa@aaa.com” is entered in the ID form, 1011 is entered in the password form, and the correct password corresponding to the entered ID is entered. Will be authenticated. If “bbb@bbb.com” is entered in the ID form, authentication is performed in the same manner if the password form is entered 1017. Therefore, the sender of the electronic document may separately calculate the password corresponding to the ID by the calculation logic of the Java script embedded in the password form (part A in FIG. 5) and provide the password separately to the distribution destination. . Of course, the calculation logic of the Java script embedded in the password form may be different from that of FIG.

  According to the flowchart shown in FIG. 5, that is, when an electronic document including the code shown in Table 2 is used, the transmission source only has to manage a single document to be distributed, an ID to which a password is provided, and a distribution destination thereof. Therefore, the management burden on the sender is reduced. That is, an ID that can be added in the future without changing / adding the PDF document itself, by calculating a password for the ID using the same calculation formula as that embedded in the document and providing the password to the distribution destination. It becomes possible to cope with. In other words, password values need not be managed.

  The shadow form non-display, watermark form display, and content form display will be described.

  When the matching of the ID and the password is confirmed, the shadow form is set to non-display (refer to FIG. 4, step S06, FIG. 5, step S24), whereby the document contents of all pages hidden by the shadow form are displayed. Is disclosed. That is, for example, the state of the shadow form is confirmed at the start of the program as shown in the code in Table 3 below, and when the condition is satisfied in the program, the document content is covered as shown in the code in Table 4 below. You can change the display attribute of the shadow form to hide.

  In addition, when the consistency between the ID and the password is confirmed, the content form including the watermark form and the document content is displayed on all pages (see FIG. 4, step S06, FIG. 5, step S24). This makes it possible to display watermark information and document contents that are desired to be displayed only when the matching between the ID and the password is confirmed. That is, for example, at the start of the program, the status of the ID form, watermark form, and content form is confirmed as shown in Table 5 below, and when the conditions are satisfied in the program, the codes in Table 6 below The contents of the ID form are set to the watermark form as shown in FIG. 6 and the display attributes of the content form including the document contents and the watermark form including the ID are changed to display as shown in the code in Table 7 below. .

  The watermark form may be displayed on all pages. By doing so, even if some pages are leaked, the leakage source ID becomes clear.

  In the electronic document according to the present invention, a plurality of shadow forms are necessary to cover the document contents over a plurality of pages of the PDF document. Similarly, multiple watermark forms and content forms are required. In this case, if a plurality of form names are used for the same type of form, it is necessary to set or change the attributes of the plurality of forms, so that the code of the script increases accordingly.

  In order to avoid such an increase in code, it is desirable to use the same form name for the same type of form.

<< Second Embodiment >>
FIG. 7 is a flowchart of a Java script executed when saving an electronic document according to the second embodiment of the present invention. The electronic document according to the second embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise. .

  In the electronic document according to the first embodiment, since the ID and password are input when the document is opened, the content is filled in the ID form and the password form immediately before the document is saved. Furthermore, the contents of the ID form are set in the watermark form, the form is displayed, the shadow form is not displayed, and the content form is displayed. In other words, the document contents can be browsed and stored in a state where the set ID can be specified. Therefore, when the next document is opened, the ID and password are already set, and the document contents can be browsed as it is.

  Therefore, it is desirable to execute a save-time execution Java script that returns the document to the initial state when the document is opened when the document is saved. FIG. 7 is a flowchart.

  Table 8 below shows a code example of a script that deletes the contents by setting null in the ID form. Table 9 below is a code example of a script that sets the watermark form to null, returns it to the non-display state setting, and returns the content form to the non-display state. Further, Table 10 below is a code example of a script for returning the shadow form to the display state setting. Although not described below, the script for deleting the contents by setting the password form to null is substantially the same as that in Table 8.

<< Third Embodiment >>
The electronic document according to the third embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise.

  In the electronic document according to the first embodiment that uses the logic of the portion A in the flowchart shown in FIG. 5 in particular, the smaller the number of ID characters, the simpler the password value that is the calculation result. That is, when a small number of characters are input many times in the ID form, there is a possibility that the calculation formula for calculating the password value from the contents of the ID form may be analyzed.

  In order to avoid this possibility, it is desirable that the number of characters input to the ID form must be a certain number or more. For example, if the code shown in Table 11 below is executed, the number of characters to be input to the ID form can be limited to 8 or more.

  Further, regularity may be required for the ID. For example, if the code shown in Table 12 below is executed, the ID form can be limited to an e-mail address format.

  Further, a contact address for obtaining a password for the ID may be displayed. If the contact (eg, phone number, address or email address) requesting a password is entered in a portion that is not concealed by the shadow form, especially in the vicinity of the ID form and password form, the user can specify the password request destination. It is easy to know. In addition, when an online password request is possible on the Internet, the URL link of the password request destination may be arranged at the same location.

<< Fourth Embodiment >>
FIG. 8 is a flowchart of a part of an ID form Java script for an electronic document according to the fourth embodiment of the present invention (FIG. 8 (1)) and a flowchart of a part of a password form Java script (FIG. 8 (2)). ). The electronic document according to the fourth embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise. .

  The electronic document according to the fourth embodiment includes a status form. The status form is a form that is arranged in the vicinity of the ID form and the password form and indicates their input state.

  As shown in the flowchart of FIG. 8A, if a blank is included in the ID form (S42), error 1 “ID contains a blank” is set in the contents of the status form (S44). If the number of characters in the ID form is not 8 characters or more (S46), error 2 “ID must be 8 characters or more” is set in the contents of the status form (S48). If the number of characters in the ID form is not in the e-mail address format (S50), error 3 “ID requires e-mail address format” is set in the contents of the status form (S52). If no problem occurs in any of the checks in S42, S46, and S50, the input 1 “Please enter your password” is set in the contents of the status form (S54).

  Further, in the flowchart of FIG. 8B, first, ID and password authentication processing is executed (S62). If it is determined in the authentication process that the password is not correct (S64), "ID or password is incorrect" is set in the contents of the status form (S66). If it is determined that the password is correct in the authentication process (S64), “readable” is set in the contents of the status form (S68).

<< Fifth Embodiment >>
FIG. 9 is a flowchart of a part of a password form Java script for an electronic document according to the fifth embodiment of the present invention. The electronic document according to the fifth embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise. .

  Even if the ID and password are confirmed to be consistent, the date and time of the system is referred to when the document is opened, and if the date and time do not satisfy the date and time conditions set in the script, the authentication is discarded. It is possible to prohibit browsing of document contents. In the flowchart shown in FIG. 9, it is checked in step S86 whether the current date and time on the system satisfies the set date and time conditions.

  For example, Table 13 below shows codes that are executed when a password form is entered so that the document cannot be viewed after 2006.

  By using the fifth embodiment, for example, when a new version of a document is released by 2006, it becomes possible to make the current document unusable after 2006.

  Further, in combination with the fourth embodiment, it is possible to display on the status form urging to acquire a new version of the document.

<< Sixth Embodiment >>
FIG. 10 is a flowchart showing a part of a password form Java script for an electronic document according to the sixth embodiment of the present invention. The electronic document according to the sixth embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise. .

  In the electronic document according to the sixth embodiment, when the password value is generated from the ID, the date data or time data of the system at the time of opening the document is combined. As a result, the password value to be generated changes with the passage of time, so it is possible to set an expiration date for the password. In the flowchart shown in FIG. 10, in step S112, information related to the current date and time on the system is added to the password value.

  For example, the code executed when the password form is entered so that the password invariant period is one year is as shown in Table 14 below.

  According to the code shown in Table 14, the password for 2005 for “aaa@aaa.com” is “3026”, but the password for 2006 is “3027”, and the 2005 password is used to view the document in 2006. I can't.

  In combination with the fourth embodiment, it is possible to display on the status form to prompt the user to obtain a new password after 2006.

<< Seventh Embodiment >>
FIGS. 11A and 11B are flowcharts of a part of a password form Java script for an electronic document according to the seventh embodiment of the present invention. The electronic document according to the seventh embodiment is substantially the same as the electronic document according to the first embodiment, and includes the components of the electronic document according to the first embodiment as a premise. .

  The electronic document according to the seventh embodiment changes display content or non-display content depending on the input ID.

  In the electronic document according to the seventh embodiment, after the authentication of the ID and the password is performed, the display object is selectively displayed according to the conditions regarding the ID. In the flowchart shown in FIG. 11A, when the ID is “aaa@aaa.com”, the content form “Contens_aaa” is displayed (S126, S128), and the ID is not “aaa@aaa.com”. Displays a content form “Contens_bbb” (S126, S130).

  For example, the code executed when entering the password form that displays the document content aaa only when the ID is “aaa@aaa.com” and displays the document content bbb for other IDs is as follows: Table 15 below.

  The control of changing the display content or non-display content according to the input ID may be performed by non-display or display of the shadow form. In the flowchart shown in FIG. 11B, when the ID is “aaa@aaa.com”, only the shadow form “Shadow_aaa” is hidden (S146, S148), and the ID is “aaa@aaa.com”. If not, only the shadow form “Shadow_bbb” is hidden (S146, S150).

  For example, when the ID is “aaa@aaa.com”, only the shadow form “Shadow_aaa” is hidden in order to display only the contents of a document, and when the ID is not “aaa@aaa.com” Table 16 below shows the code executed when the password form is entered so as to hide only the shadow form “Shadow_bbb” in order to display only the document contents.

For example, as shown in FIG. 21 (1), when “ricoh@ricoh.co.jp” is entered in the ID form, “jp”, which is the last two characters, is not displayed because of the limitation on the number of characters. For this reason, if the ID and password do not match due to an input error, etc., all the characters of the ID are not displayed, so it is not possible to confirm at a glance which of the ID and password is wrong. It is necessary to operate the input device.

  In the electronic document according to the thirteenth embodiment, when inputting or displaying characters exceeding the number of characters that can be displayed on the size, a form for automatically changing the character size is adopted as the collation data input field for inputting the ID. . As a result, even when a long ID exceeding the number of characters that can be displayed on the size of the form is input, it is possible to display all the characters without losing a part before and after the ID. In FIG. 21 (2), when “ricoh@ricoh.co.jp” is entered in the ID form, the last two characters are not displayed with the default character size, but the character size is automatically reduced. In FIG. 21 (2), all characters including “jp” which are not displayed are displayed. As a result, if the ID and the password do not match, it can be confirmed at a glance whether or not there is an error in the ID.

<< Nineteenth embodiment >>
FIG. 27 is a schematic display diagram of an electronic document according to the nineteenth embodiment of the present invention. The upper left part of FIG. 27 is a display diagram from the first page to the second page (from top to bottom) before data is input into the data input field. The lower right part, upper right part and lower left part of FIG. It is a display figure of the 1st page to the 2nd page after input (from top to bottom).

  In the prior art, when the password to be verified is automatically generated from the ID, if the time data generated by the computer is used for the (automatic) calculation, the password is often changed periodically. Therefore, the document cannot be browsed unless the viewer notices the password change. In addition, since the contact information of the document source is not known, there is a possibility that a valid new password cannot be obtained. Referring to FIG. 27, according to the prior art, when an ID and a valid password are input to the electronic document in the initial state shown in the upper left part of FIG. 27, the document contents can be browsed as shown in the upper right part of FIG. Transition to the state. However, when an invalid old password is input, the state transitions to a state where the document contents cannot be viewed as shown in the lower right part of FIG. 27 and is displayed only when the password is incorrect. At this time, the viewer hardly notices that the password must be updated. I also don't know where to get my new password.

  In the electronic document according to the nineteenth embodiment, when an invalid password is input, an indication that the password is old and invalid and a contact for obtaining a valid password are displayed (lower left portion of FIG. 27). ). As a result, the viewer can know that the password has become invalid, and can specify a contact for updating the password.

  In the display example shown in FIG. 27, the initial state is a state as shown in the upper left part of FIG. When the ID and password are entered after the date and time when the old password became invalid, a transition is made as shown in the lower left part of FIG. 27, and a warning that the password has become invalid is displayed and the updated password is confirmed. The contact address of the document sender such as the URL and telephone number is displayed. When a URL is displayed, the content of the URL may be displayed by a browser when the URL is clicked. Thus, by displaying that the password has become invalid, the viewer can easily confirm the necessity of password update. By displaying a contact for confirming the update password, password update is facilitated.

<< 20th Embodiment >>
FIG. 28 is a schematic display diagram of an electronic document according to the twentieth embodiment of the present invention. The left part of FIG. 28 is a display diagram from the first page to the second page before data is input to the data input field (from top to bottom), and the right part of FIG. 28 is the data after data is input to the data input field (from top to bottom). Down) A display diagram from the first page to the second page.

  In the prior art, when it is necessary to input an ID and a password, even if an incorrect ID or an incorrect password is input, such re-input is allowed without limitation. Therefore, when a password is uniquely generated for a certain ID, combinations of letters and numbers and the number of digits are easily predicted. Therefore, the password is effectively stolen by brute force attacks. It may be done.

  In the electronic document according to the twentieth embodiment, when an incorrect ID or an incorrect password is input a predetermined number of times, the data input field for inputting the ID and password is set as a read-only area or a non-display area To. By making the ID and password incapable of being input in this way, it is possible to prevent the ID and password from being illegally acquired.

  In the example of display shown in FIG. 28, the initial state is a state as shown in the left part of FIG. When the input of an incorrect ID or an incorrect password has reached a predetermined number of times, the data input column for the ID and password is changed to a state where input is impossible as shown in the right part of FIG. Then, the fact that input is impossible is separately displayed in those data input fields. Those data input fields may be hidden. In this case, if the ID and password are to be input again, it is necessary to close the file and reopen the document file. For this reason, even if a brute force attack is attempted, more time is required for password analysis. As described above, it is possible to make it difficult to illegally obtain an ID and a password by limiting the number of times the ID and password are input to the data input column and making a transition to a state in which the ID and password cannot be input.

<< 21st embodiment >>
FIG. 29 is a schematic display diagram of an electronic document according to the twenty-first embodiment of the present invention. The left part of FIG. 29 is a display diagram from the first page to the second page before data input to the data input field (from top to bottom), and the right part of FIG. 29 is the data after data input to the data input field (from top to bottom). Down) A display diagram from the first page to the second page.

  In the prior art, when the ID and password need to be input, even if the correct ID and password are once input, the ID or password value may be erroneously changed by an unintended operation. At this time, there is a problem that if the ID and password are verified again and it is determined that an incorrect ID or an incorrect password has been input, the document content cannot be browsed.

  In the electronic document according to the twenty-first embodiment, when a correct ID and password are input, a data input field for inputting the ID and password is set as a read-only area or a non-display area. By making the ID and password incapable of being input in this manner, it is possible to prevent the ID or password value from being erroneously changed by an unintended operation.

  In the display example shown in FIG. 29, the initial state is a state as shown in the left part of FIG. When the correct ID and password are input, the ID and password data input fields are changed to a state incapable of input as shown in the right part of FIG. Further, these data input fields may be hidden. In this case, even if data is erroneously input to the data input field of the ID or password by an unintended operation, the values of those data input fields are not changed, so that the document content remains in a viewable state. In this way, data contents are prevented from being accidentally changed by an unintended operation in the data entry field for ID or password, and the document contents can always be viewed after the correct ID and password are entered. By doing so, it is possible to improve the convenience of browsing the document by the viewer.

<< Twenty-second embodiment >>
FIG. 30 is a schematic display diagram of an electronic document according to the twenty-second embodiment of the present invention. The left part of FIG. 30 is a display diagram from the first page to the second page before data input to the data input field (from top to bottom), and the right part of FIG. 30 is the data after data input to the data input field (from top to bottom). Down) A display diagram from the first page to the second page.

  In the prior art, an object (shadow form) that makes a document unviewable is separated from an object (watermark form) that displays an ID or the like in a viewable state. That is, it is composed of at least two or more objects. Therefore, the number of objects in the document increases, and the size of the document file increases.

  In the electronic document according to the twenty-second embodiment, the functions of the two types of objects are combined into one, and the same effect as before can be obtained with fewer objects.

  In the display example shown in FIG. 30, the initial state is the state as shown in the left part of FIG. Here, an object in which an object that makes a document unviewable and an object that displays an ID or the like in a viewable state (hereinafter referred to as an integrated object) has a background color, so the document content is It is in a state where it is not viewed. When the correct ID and password are entered, the background color of the integrated object is changed to transparent as shown in the right part of FIG. 30 so that the document contents can be viewed and entered in the data entry field for entering the ID. The content is assigned to the integrated object, and a transition is made to a state in which the ID is displayed on the integrated object. In this way, by integrating the object that makes it impossible to view a document and the object that displays an ID or the like when it is in a viewable state, the number of objects that the document has can be reduced while maintaining the same effect as the conventional technology. Therefore, the document file size can be reduced.

<< 23rd embodiment >>
FIG. 31 is a schematic enlarged display diagram (upper part of FIG. 31) of a conventional electronic document and a schematic enlarged display figure (lower part of FIG. 31) of the electronic document according to the twenty-third embodiment of the present invention.

  In the prior art, when an object (watermark form) for displaying an ID or the like is displayed superimposed on the document content, the object is displayed before the document content. For this reason, if the object character is thicker than the document content character, the probability that the object character conceals the document content character is increased. At this time, characters in the document contents are difficult to be recognized.

  In the electronic document according to the twenty-third embodiment, characters of a thin font are used for the characters of an object for displaying an ID or the like. As a result, the document content is displayed better, and the characters of the document content are more recognized.

  In the example of display shown in FIG. 31, an object for superimposing an ID or the like on the document content is displayed. An example in which a thick font (upper part of FIG. 31) and a thin font (lower part of FIG. 31) are used as object characters is displayed. In the display example at the top of FIG. 31, “Lucida Sans Unicode” is used as the font, and in the display example at the bottom of FIG. 31, “Courier New” is used as the font. The two types of fonts are both monospaced fonts, use the same font size of 48 points, and have the same object position.

  In the example at the top of FIG. 31, the area where the characters of the object displaying the ID and the like and the characters of the document content overlap is large. In particular, the recognizability of the upper “C” character and the lower “C” character is greatly reduced. On the other hand, in the example at the bottom of FIG. 31, the area in which the characters of the object displaying the ID and the like and the characters of the document content are overlapped is small. In the example in the upper part of FIG. 31, the lowering of the recognizability of the upper “C” character and the lower “C” character is small. That is, it is in a state where characters can be sufficiently recognized. In this way, by using a thin font character for the object character for displaying the ID or the like, the area where the character of the object for displaying the ID or the like and the character of the document content are overlapped can be reduced. Decrease in recognition can be prevented.

<< 24th Embodiment >>
FIG. 32 is a schematic enlarged display diagram (upper part of FIG. 32) of a conventional electronic document and a schematic enlarged display diagram (lower part of FIG. 32) of the electronic document according to the twenty-fourth embodiment of the present invention.

  In the prior art, when an object (watermark form) for displaying an ID or the like is displayed superimposed on the document content, the object is displayed before the document content. For this reason, when a proportional font is used for the character of the object, especially when characters such as “i” and “j” are used, the probability that the character of the object conceals the character of the document content increases. At this time, characters in the document contents are difficult to be recognized.

  In the electronic document according to the twenty-fourth embodiment, characters of a monospaced font are used as the characters of an object for displaying an ID or the like. As a result, the content of the document hidden in the proportional font is displayed better, and the characters of the document content are more recognized.

  In the example of display shown in FIG. 32, an object in which an ID or the like is superimposed on the document content is displayed. An example is shown in which a proportional font (upper part of FIG. 31) and a monospaced font (lower part of FIG. 32) are used as object characters. In the display example in the upper part of FIG. 32, “Century Gothic” is used as the font, and in the display example in the lower part of FIG. 32, “Courier New” is used as the font. The two types of fonts both use the same font size of 48 points, and the positions of the objects are the same.

  In the example in the upper part of FIG. 32, the area in which the characters of the object displaying the ID and the like and the characters of the document content overlap is large. In particular, the recognizability of the upper “C” character is greatly reduced, and the uppercase “I” (eye) in the middle may be erroneously recognized as the lowercase “l” (el). On the other hand, in the example at the bottom of FIG. 32, the number of characters displayed in the same area is only five characters, which is much smaller than the 17 characters in the example at the top of FIG. Therefore, the area in which the character of the object displaying the ID and the character of the document content overlaps is small. In the example in the upper part of FIG. 32, the lowering of the recognizability of the letter “C” in the upper stage and the letter “I” in the middle stage in the example in the upper part of FIG. 32 is small. That is, it is in a state where characters can be sufficiently recognized. In this way, by using a monospaced font character for an object or the like displaying an ID or the like, it is possible to reduce the area in which the object or character displaying the ID or the like overlaps the document content. It is possible to prevent a decrease in recognition of

<< 25th Embodiment >>
FIG. 33 is a schematic enlarged display diagram of the conventional electronic document (upper part of FIG. 33) and a schematic enlarged display diagram of the electronic document according to the twenty-fifth embodiment of the present invention (lower part of FIG. 33).

  In the prior art, when an object (watermark form) for displaying an ID or the like is displayed superimposed on the document content, the object is displayed before the document content. For this reason, if characters of the same color as the document content are used for the object characters, the object characters and the document content characters are confused. At this time, characters in the document contents are difficult to be recognized.

  In the electronic document according to the twenty-fifth embodiment, a character that is lighter than the character color of the document content is used for the character of the object that displays the ID or the like. This facilitates the distinction between the text of the document content and the text of the object, and the text of the document content is more recognized.

  In the display example shown in FIG. 33, an object in which an ID or the like is superimposed on the document content is displayed. As an object character, an example in which a character having the same color as the character of the document content (upper part of FIG. 33) and a character lighter than the character of the document content (lower part of FIG. 33) are displayed. In the display example at the top of FIG. 33, black is used as the character color, and in the display example at the bottom of FIG. 33, gray is used as the character color. The two types of fonts are the same font, and the positions of the objects are the same.

  In the example in the upper part of FIG. 33, the characters of the object displaying the ID and the like are confused with the characters of the document content. In particular, the recognizability of the upper “C” character and the middle “C” character is greatly reduced. On the other hand, in the example in the lower part of FIG. 33, it is easy to identify the character of the object displaying the ID and the character of the document content. In the example in the upper part of FIG. 33, the lowering of the recognizability of the upper “C” character and the middle “C” character with low recognizability is small. That is, it is in a state where characters can be sufficiently recognized. In this way, by using a character lighter than the character color of the document content as the character of the object displaying the ID or the like, it becomes easy to distinguish between the character of the object displaying the ID or the like and the character of the document content. Therefore, it is possible to prevent a decrease in the recognizability of characters in the document content.

<< Twenty-sixth embodiment >>
FIG. 34 is a schematic enlarged display diagram (upper part of FIG. 34) of a conventional electronic document and an enlarged schematic display view (lower part of FIG. 34) of the electronic document according to the twenty-sixth embodiment of the present invention.

  In the prior art, when an object (watermark form) for displaying an ID or the like is displayed superimposed on the document content, the object is displayed before the document content. For this reason, when the progress direction of the object character line and the progress direction of the document content line are the same, the probability that the object character conceals the document content character is increased. At this time, characters in the document contents are difficult to be recognized.

  In the electronic document according to the twenty-sixth embodiment, there is an angle in the direction of movement of the character of the object with respect to the direction of movement of the character of the document content. As a result, when the two characters have the same traveling direction, the concealed document content is displayed more, and the document content characters are more recognized.

  In the display example shown in FIG. 34, an object in which an ID or the like is superimposed on the document content is displayed. With respect to the progress direction of the document content line, the object text line progress direction is the same (upper part of FIG. 34) and different (lower part of FIG. 34). In the display example in the upper part of FIG. 34, the progress direction of the object character is the same as the progress direction of the document content line. In the display example in the lower part of FIG. The direction of travel is 90 degrees. In the above two figures, the same font size of 48 points is used, and the object positions are the same.

  In the example in the upper part of FIG. 34, the area in which the characters of the object displaying the ID and the like and the characters of the document content overlap is large. In particular, the recognizability of the characters “R” and “H” in the document contents is greatly reduced. Also, the recognizability of all characters of the object is greatly reduced. On the other hand, in the example at the bottom of FIG. 34, the area where the character of the object displaying the ID or the like and the character of the document content overlap is small, and only the characters “C” and “O” of the document content are the characters of the object. Is superimposed. For this reason, the decrease in the recognizability of characters in the document content is small. In the object, only “C” is superimposed on the character of the document content, and all characters can be sufficiently recognized. Thus, by having an angle in the direction of movement of the character of the object with respect to the direction of movement of the character of the document content, the area in which the character of the object displaying the ID and the character of the document content overlaps is reduced. It is possible to prevent deterioration in the recognizability of document contents and object characters.

<< Twenty-seventh embodiment >>
FIG. 35 and FIG. 36 are schematic display diagrams of a conventional electronic document, and explain the problems of the conventional electronic document. FIG. 37 is a schematic display diagram of an electronic document according to the twenty-seventh embodiment of the present invention.

  In the prior art, when an object (watermark form) that displays an ID or the like is displayed superimposed on the document content, there is no standard for the number of objects to be arranged. For this reason, excess and deficiency may occur in the quantity. That is, when the amount is excessive, the readability of the document content is lowered, and when the amount is insufficient, the document content is not properly protected.

  As shown in FIG. 35 (1), when an English sentence is displayed as an electronic document, the starting point of the document content is the upper left, the progress direction of the line of the document content is right, and the progress direction when the line increases is lower. It is. At this time, considering the probability that the document contents exist on the page, the probability on the left side of the page is higher than that on the right side, and the probability on the upper side of the page is higher than that on the lower side. That is, as shown in FIG. 35 (2), the darker the background color, the higher the probability of existence of the document contents in general.

  Here, an example is considered in which the vertical and horizontal sides of the page are both equally divided into three, and the page is divided into nine grids (FIG. 36 (1)). Columns in 9 divisions are denoted by symbols A, B, and C from the left, and rows in 9 divisions are denoted by symbols 1, 2, and 3. Each of the nine divided areas is represented as A-1, B-1, C-1, A-2, B-2, C-2, A-3, B-3, and C-3.

  In this case, the probability that the document content exists on the page is highest in A-1, and the probability decreases as it goes to the right side of B-1, C-1. Moreover, it becomes so low that it goes to A-2, A-2, and A-3 from A-1. At this time, the probability at C-3 is the lowest. As shown in FIG. 36 (1), when an object for displaying an ID or the like is superimposed on the document content in all nine divided areas, the entire area of the page can be covered with the object. However, the number of objects increases, and the readability of the document contents is greatly reduced.

  As shown in FIG. 36 (2), an object that displays an ID or the like in an area where the existence probability of the document content is high among the nine divided areas, for example, A-1, A-2, B-1, and B-2. When superposed on the document content, the number of objects becomes four, which is half or less compared to nine in FIG. 36 (1), and the readability can be improved. Further, since these four objects are arranged in an area where the existence probability of the document content is high, the probability that characters such as an ID are superimposed on the document content hardly decreases as compared with the example shown in FIG. . However, since there is no object in the column “C” and the row “3”, the effect of protecting the document content is reduced for a page that uses only that row or column, or a page that uses the whole. .

  In the electronic document according to the twenty-seventh embodiment, the document content area is divided into a grid pattern, and one object is placed in each row and column of the divided document content area. As a result, it is possible to suppress a decrease in the recognizability of characters in the document content while sufficiently protecting the document content with the same number of objects as the number of divisions on one side of the document.

  As shown in FIG. 37, an object that displays IDs, for example, on A-1, B-2, and C-3 in a stepwise manner from an area having a high document content existence probability to an area having a low probability of existence among nine divided areas. When superposed, the number of objects can be reduced to three compared to the example (9) in FIG. 36 (1) and the example (4) in FIG. 36 (2). This increases the readability of the document content. In addition, since two of the three objects are arranged in areas A-1 and B-2, which have high probability of existence of the document content, the probability that the character of the object is superimposed on the document content is shown in FIG. Compared with the example of 1) and the example of FIG. In addition, since objects exist in all the columns “A”, “B”, and “C” and all the rows “1”, “2”, and “3”, only one row or one column is present. The effect of protecting the document content is hardly deteriorated even for a page that uses or the whole page.

<< Twenty-eighth embodiment >>
38, 39, and 40 are schematic display diagrams of the electronic document according to the twenty-eighth embodiment of the present invention.

  Note that, in the electronic document according to the twenty-eighth embodiment as well, consider that the vertical and horizontal sides of the page are both equally divided into three, and the page is divided into nine in a grid pattern (see FIG. 37). Columns in 9 divisions are denoted by symbols A, B, and C from the left, and rows in 9 divisions are denoted by symbols 1, 2, and 3. Each of the nine divided areas is represented as A-1, B-1, C-1, A-2, B-2, C-2, A-3, B-3, and C-3. Then, it is considered that an object (watermark form) for displaying an ID or the like is superposed on all or a part of the nine divided areas.

  In the conventional technology, when an object (watermark form) for displaying an ID is superimposed on a document content area where the viewpoint is concentrated, the document is protected to the viewer even if the number of objects is not so large. May give the impression of being excessive.

  For example, as shown in FIG. 37, an object that displays an ID or the like in an area divided into nine areas divided by a high probability of existence of the document contents, that is, A-1, B-2, and C-3. Is superimposed on the document content, the number of objects is three. It can be said that the quantity is minimized. However, when the viewer starts browsing the page, the point of view is often A-1 where the document content start point exists and B-2 which is the center of the page. At this time, if objects that display IDs and the like exist in A-1 and B-2, these objects exist in an area where the viewpoint is concentrated when the viewer starts browsing the document contents. . Then, it can be said that the viewer has the impression that the document protection is excessive, and the readability from the viewer is reduced.

  In the electronic document according to the twenty-eighth embodiment, the top region and the region near the center in the row and column traveling directions are not set as regions where objects are superimposed. This makes it possible to suppress a decrease in the readability of the document content while protecting the document content in the electronic document.

  In the example of the electronic document according to the twenty-eighth embodiment shown in FIG. 38 (1), the object installed in A-1 is moved to B-1 based on the arrangement of the objects shown in FIG. The object arranged at B-2 is moved to A-2. This is to avoid placement of objects in an area where the viewpoint is concentrated when the viewer starts browsing the document contents. Similarly to FIG. 37, objects exist in all the columns “A”, “B”, and “C”, and all the rows “1”, “2”, and “3”. In addition, the effect of protecting the document content is hardly deteriorated even for a page using only one column or a page using the whole.

  It is true that moving the object from A-1 to B-1 as described above is moving from a region where the document content existence probability is high to a low region. However, since another object is moved from B-2 to A-2 (where the document content existence probability is high), this does not impair the effect of protecting the document content.

  Incidentally, English is included in the example of the document shown in FIG. The starting point of the document content is the upper left, the direction of progress of the document content line is from left to right, and the direction of progress when the line increases is from top to bottom. In the case of another language, for example, in Japanese, the starting point of the document content is at the upper right, the progression direction of the document content line is from top to bottom, and the progression direction when the number of lines increases is from right to left It is. In this case, the arrangement of the objects is as shown in FIG. For example, in the case of Persian, the starting point of the document content is the upper right, the progress direction of the lines of the document content is from right to left, and the progress direction when the lines increase is from the top to the bottom. In this case, the arrangement of the objects is as shown in FIG.

<< Twenty-ninth embodiment >>
FIG. 40 is a schematic display diagram of an electronic document according to the twenty-ninth embodiment of the present invention.

  In the prior art, when an object (watermark form) that displays an ID or the like is displayed superimposed on the document content, there is no standard for the number of objects to be arranged. For this reason, excess and deficiency may occur in the quantity. That is, when the amount is excessive, the readability of the document content is lowered, and when the amount is insufficient, the document content is not properly protected.

  In the example of the electronic document shown in FIGS. 37 and 38, the vertical and horizontal sides of the page are both equally divided into three, and the page is divided into nine grids. Then, one object is arranged in each row and column of the divided document content area.

  However, one side can be considerably longer than the other. Also, as the nature of the document content, it may be desirable to increase the number of divisions on one side than on the other side.

  In the electronic document according to the twenty-ninth embodiment, the document content area is divided into a grid pattern, and the same number of objects as the larger number of divisions are prepared among the vertical and horizontal sides. Is placed. This suppresses a decrease in the recognizability of characters in the document content while sufficiently protecting the document content.

  In the example of the electronic document shown in FIG. 40, the horizontal side of the page is divided into three equal parts, and the vertical side is divided into four equal parts. Therefore, the page is divided into 12 in a grid pattern. Columns in 9 divisions are denoted by symbols A, B, C from the left, and rows in 9 divisions are denoted by symbols 1, 2, 3, 4 from the top. The nine divided areas are A-1, B-1, C-1, A-2, B-2, C-2, A-3, B-3, C-3, A-4, B- 4, expressed as C-4. At this time, the probability that the document content exists on the page is highest in A-1, and decreases toward the right side of B-1, C-1. Moreover, it becomes so low that it goes to A-2 from A-1, A-2, A-3, and A-4. After all, C-4 is the lowest.

  Further, the rows “1”, “2”, and “3” are arranged in the same manner as in FIG. Regarding the row “4”, the object is arranged in any region (B-4 in FIG. 40). The number of objects for protecting the document is four, which is the same as the number of divisions on one side. In this way, the number of objects is minimal, but it is possible to improve readability.

  It is also possible to improve readability by avoiding the placement of objects in A-1, where the starting point of the document content exists, B-2, and B-3, which are the center of the page. In addition, since objects exist in all the columns “A”, “B”, “C” and all the rows “1”, “2”, “3”, “4”, one row or Even for a page using only one column or a page using the whole, the effect of protecting the document content is hardly lowered.
