Abstract

Conventionally, it is the provider of each information that sets access restrictions for shared information. For this reason, if the information provider determines that the confidentiality level that should be increased is low and does not restrict access, or if the information provider or the administrator requested by the information provider forgets to set access restrictions, confidential information Could leak. Therefore, set a word (restricted phrase) that should be restricted in advance and a password for releasing the restriction, and confirm whether the restricted information is included in the shared information requested to be read at the time of the browsing request. When a restricted phrase is included, an information processing method is provided that restricts browsing of shared information unless an accurate password is input.

Description

  The present invention relates to an information processing method in an information processing apparatus that performs browsing processing of shared information, and in particular, a provider of confidential information does not consciously limit the browsing of the confidential information without providing the confidential information provided. The present invention relates to an information processing method, an information presentation program, and an information processing apparatus that allow browsing to a predetermined user.

  In today's information society, information is shared everywhere. For example, in a company, information that only officers are allowed to view, information that only people in the department related to a specific project are permitted to view, information that is permitted to be viewed by employees, and anyone can view The shared information is managed according to the confidentiality level such as open information.

The shared information is, for example, an in-house LAN (Local Area
It is stored and managed in a predetermined shared server in (Network). The shared server is a client terminal (PC (Personal
(Computer), PDA (Personal Digital Assistance), mobile phone, etc.) Restrict the information that can be viewed according to the user, request the input of a predetermined password, and restrict the viewing to only the authorized password input person To restrict access.

  In addition, on the Internet used by an unspecified number of users, general users can post articles posted as weblogs (blogs) by the website administrator and electronic bulletin boards (BBS: Bulletin Board System) established on the website. Articles posted (written on the BBS) are also one piece of information managed as shared information because they are freely viewed by an unspecified number of users who visit the homepage.

Similar to the access restriction for each confidential level in the in-house shared server, various access restrictions for restricting browsing of articles to specific users are performed on the homepage on the Internet. For example, when a user accesses a web server that stores a homepage, the user is prompted to enter a password when browsing a predetermined article, or from a client terminal that has a predetermined IP (Internet Protocol) address. For example, the connection request is blocked. In addition, according to Patent Document 1, a password is set individually or collectively for a plurality of confidential parts embedded in a document, and the password entered when the document is called matches the set password. A Japanese document creation device that can display and print the confidential part is described.

  In the present embodiment, when there is a phrase (restricted phrase) that should be restricted for browsing in the content of each article stored in the article DB 131, the entry restriction is requested by requesting the input of a password at the time of browsing request for the article. Do. Therefore, a data configuration example of the password table 132 that stores restriction words / phrases for restricting browsing and passwords for canceling the browsing restriction will be described next.

  The password for canceling the browsing restriction is set for each word (regulation word / phrase) whose browsing should be restricted. Alternatively, a category that conceptually bundles a plurality of restricted words may be prepared, and a password may be set for each category.

  4 is a data configuration example of the password table 132. FIG. 4A is a diagram illustrating a case where a password is set for each restricted phrase, and FIG. 4B is a diagram illustrating a case where a password is set for each category. For example, in FIG. 4A, the password “getmoney” is associated with the restricted phrase “wholesale price”, the password “getcustomer” is associated with the restricted phrase “sales strategy”, and the restricted phrase “benchmark” is associated with The password “gethighscore” is associated.

  In FIG. 4B, the password “howmuch” is associated with the category “price information”, the password “howto” is associated with the category “trade secret”, and the password “howtune” is associated with the category “performance information”. Are associated. As shown in FIG. 4B, when a password is set for a category, a correspondence table that specifies the restricted words included in each category is required, which is as follows.

  FIG. 5 is a data configuration example of a phrase-to-category correspondence table showing the relationship between categories and phrases. For example, FIG. 5 shows that the category “price information” includes restriction words such as price, yen, ¥ (yen symbol), wholesale price, sales price, and suggested retail price. Similarly, it is shown that the category “trade secret” includes restricted words such as sales strategy, other company trends, regional information, customer information, confidential information, confidentiality, and confidentiality. For other categories, it is indicated that a plurality of restricted words are included.

  The administrator of the information processing apparatus 1 and the article browsing service can set the browsing policy flexibly by further classifying the restricted words into categories along a predetermined subject and utilizing the password table and the correspondence table. it can.

  When a password is set for a category as shown in FIG. 4B, the correspondence table shown in FIG. 5 is also stored in advance in the storage unit 13 of the information processing apparatus 1. The information processing apparatus 1 can identify the category to which the restricted phrase belongs by referring to the correspondence table of FIG.

  The password stored in the password table 132 is distributed in advance to users of the article browsing service provided by the information processing apparatus 1. The pre-distribution may be performed by any means such as e-mail, mail by document, or verbal notification.

  FIG. 6 is a diagram illustrating an example of a screen for distributing a password to a user by e-mail as an example. FIG. 6A illustrates a case where a password is set for each word, and FIG. 6B illustrates a password set for each category. FIG. Therefore, in FIG. 6A, passwords for each restricted phrase are listed, and in FIG. 6B, passwords for each category are listed.

  Next, the operation of the information processing apparatus according to the present embodiment during the article browsing process will be described.

  FIG. 7 is a flowchart illustrating the browsing process of the information processing apparatus 1 according to the embodiment of the present invention. In the present embodiment, articles are posted in advance, and articles posted in the article DB 131 are accumulated (S0). In step S0, the information processing apparatus 1 displays the article posting form shown in FIG. 2 on the output unit 17, and the information input by the user via the input unit 16 in the data format shown in FIG. To store.

  First, the information processing apparatus 1 receives a search request for articles stored in the article DB 131 (S1). This search request includes a search condition for specifying what kind of article is to be searched. In step S1, the search request is received via the screen (search condition input form) output by the information processing apparatus 1 to the output unit 17 from the search condition (search keyword or category specified by the user). ) Is input.

  FIG. 8 is a diagram illustrating an example of a screen for inputting a search condition for searching for an article. The search condition input form shown in FIG. 8 is generated using, for example, HTML. The keyword search column 81 is a column for inputting a search keyword. The AND / OR selection column 82 is a column for selecting and inputting “AND” or “OR” from the pull-down menu. When “AND” is selected, an AND search using a plurality of words input in the keyword search field 81 is performed. When “OR” is selected, a plurality of words input in the keyword search field 81 are selected. Used OR search is performed.

  The category selection check box 83 can be clicked via the input unit 16. This corresponds to the data item “category” of the article DB 131 in FIG. 3, and becomes a selection column for narrowing the selection target of articles in the article DB 131 to the category with the check mark 84. When the user clicks the check box, a check mark 84 is added to the check box of the selected category. In FIG. 8, since the category “trade secret” is selected, when the search is started in this state, in the article DB 131, articles whose data item “category” is trade secret are searched.

  The clear button 85 is a button that can be clicked by the user via the input unit 16. When the user clicks the clear button 85, the information input in the above fields 81 to 83 is deleted, and the input of the search request (search condition) is stopped.

  The search button 86 is also a button that can be clicked by the user via the input unit 16. When the user clicks the search button 86, the article is searched based on the search conditions input in the above fields 81 to 83.

  Returning to FIG. 7, when the search button 86 is clicked in FIG. 8, a search condition is input to the information processing apparatus 1, and the information processing apparatus 1 uses the keyword input in the keyword search field 81 to The article DB 131 is referenced to search for articles (AND search or OR search) in which the search item is included in the data item “content” (see FIG. 3) (S2). At this time, if there is a category with a check mark 84 in the category selection check box 83, first, the keyword search is executed by narrowing the search target category in the article DB 131 to the corresponding category.

  If there is no article corresponding to the search condition as a result of executing the search based on the search condition (S2 No), the information processing apparatus 1 displays on the output unit 17 that the corresponding information does not exist in the article DB 131 (S3).

  FIG. 9 is a diagram illustrating an example of a screen for notifying the absence of an article that matches the search condition in step S3. The return button 91 is a button that can be clicked by the user via the input unit 16. When the user clicks the return button 91, the search condition form of FIG. 8 is displayed, and the user can input a new search condition.

  Returning to FIG. 7, if there is an article corresponding to the search condition as a result of executing the search based on the search condition (S2 Yes), the information processing apparatus 1 identifies the article ID. Then, the information processing apparatus 1 refers to the article DB 131 and determines whether there is an article that includes a restricted phrase in the content of the article corresponding to the identified article ID (= the article corresponding to the search condition) (S4). In the process of step S4, when a password is set for each restricted phrase, the information processing apparatus 1 refers to the article DB 131 and sets the “content” (see FIG. 3) for each article corresponding to the search condition. It is confirmed whether or not the restricted words included in the word password table of FIG. 4A are included.

  When a password is set for each category rather than for each restricted word / phrase, the information processing apparatus 1 refers to the article DB 131 for each article corresponding to the search condition in its “content” (see FIG. 3), FIG. In addition, it is confirmed whether or not a restricted word included in the correspondence table is included, and when an article including the restricted word is found, a category to which the restricted word belongs is specified.

  FIG. 10 is a data configuration example of intermediate data generated in association with the process (step S4) for specifying whether or not a restricted word is included in an article corresponding to the search condition. FIG. 10A shows a password for each word. 10B is a diagram illustrating a case where a password is set for each category. The intermediate data is stored in the RAM 12, for example.

  FIG. 10A includes data items “article ID”, “confidential flag”, and “restricted phrase”. “Article ID” is an identifier that identifies an article searched as an article corresponding to the search condition among the articles included in the article DB 131. Therefore, unlike the “article ID” in the article DB 131, a skipped numerical value may be stored as shown in FIG. 10A.

  The “confidential flag” is flag information indicating whether or not the restricted word is included in the article corresponding to the search condition. If included, ON is stored, and OFF is stored if not included. “Regulated word / phrase” indicates a restricted word / phrase included in an article corresponding to the search condition.

  For example, FIG. 10A shows a state where the confidential flag of the corresponding entry is ON because the content of the article whose article ID is 54 includes “wholesale price” set in the restricted phrase. . The article whose article ID is 38 does not include a restricted phrase, and the confidential flag is OFF.

  FIG. 10B includes a data item “category” in addition to the data items of FIG. 10A. “Category” indicates the category to which the restricted phrase included in the article corresponding to the search condition belongs. The relationship between the restricted words and categories is specified by the correspondence table shown in FIG.

  For example, FIG. 10B shows a state where the confidential flag of the corresponding entry is ON because the content of the article whose article ID is 54 includes “wholesale price” set in the restricted phrase. . Referring to the correspondence table of FIG. 5, the category including the restriction word “wholesale price” is “price information”, and “price information” is stored in the “category” of the article whose article ID is 54.

  Returning to FIG. 7, in step S <b> 4, the information processing apparatus 1 sets a password input field for an article including a restricted word / phrase if the restricted word / phrase is included in the article corresponding to the search condition (S <b> 4). Specifically, in the process of step S5, the information processing apparatus 1 sets “ON” to the “confidential flag” (intermediate data in FIG. 10A or B) of an article that includes a restricted phrase among articles corresponding to the search condition. And the restricted phrase included in the article is stored in “restricted phrase” (intermediate data in FIG. 10A or B). If a password is set for each category, the information processing apparatus 1 further refers to the correspondence table in FIG. 5, identifies the category to which the restricted phrase included in the article belongs, and “category” (FIG. 10B). Intermediate data).

  The information processing apparatus 1 skips the process in step S5 if the article corresponding to the search condition does not include a restricted phrase (S4 No). When the processing of step S5 is completed, the information processing apparatus 1 displays the search result on the output unit 17 (S6). The search result is displayed, for example, as a list of subject names of articles corresponding to the search condition.

  Therefore, in step S6, the information processing apparatus 1 refers to the intermediate data in FIG. 10 and acquires the article ID of the article corresponding to the search condition. Then, the information processing apparatus 1 extracts a subject corresponding to the acquired article ID in the article DB 131 and generates, for example, an HTML source file that displays the extracted subject as a list. At that time, the information processing apparatus 1 inputs the password for the article including the restricted phrase at the place where the description for displaying the subject of the article corresponding to the article ID whose confidential flag is ON is described in the source file. <Form> tag is inserted.

  FIG. 11 is a diagram showing an example of a screen for displaying a search result when a password is set for each word in step S6. FIG. 11 shows a search result when the word “test” is input to the keyword search field 81 of FIG. 8 as a search keyword. FIG. 11 shows the names of four articles corresponding to the search condition.

  In the display area 111, the subject of the first article is subject2, and it is displayed that the content of this article includes the restricted word “wholesale price”. In the display area 111, a password input field 115 for releasing the browsing restriction on the restricted word and a display button 116 for browsing the content of the article are further displayed.

  The display button 116 is a button that can be clicked by the user via the input unit 16. When the user clicks the display button 116, a browsing request is input to the information processing apparatus 1 together with an article ID that specifies an article corresponding to the subject subject 2. The article ID of the article corresponding to the subject “subject2” is obtained by referring to the intermediate data (FIG. 10A or 10B) used for generating the search result screen of FIG.

  At this time, the password input in the password input field 115 is also input to the information processing apparatus 1 together with the browsing request. The information processing apparatus 1 displays the content of the article corresponding to the subject “subject 2” on the output unit 17 only when an accurate password for the restriction word “wholesale price” is input.

  In the display area 112, it is displayed that the subject of the second article is subject5. Since the content of this article does not include a restricted phrase, there is no password entry field in the display area 112, and a display button 117 is simply displayed.

  In the display area 113, the subject of the third article is subject9, and it is displayed that the contents of this article include the restricted words “wholesale price” and “sales strategy”. When one article includes a plurality of restricted words / phrases, a password input field for canceling the browsing restriction for each restricted word / phrase is displayed, and the display area 113 further includes password entry fields 118 and 119 and a display button. 120 is displayed. When the information processing apparatus 1 receives a browsing request by clicking the display button 120, the content of the article corresponding to the subject subject9 only when an accurate password for each restricted phrase is entered in each password entry field. Is displayed on the output unit 17.

  The display area 114 displays that the subject of the fourth article is subject12. As in the second case, the display area 114 does not have a password input field, and a display button 121 is simply displayed.

  FIG. 12 is a diagram showing an example of a screen for displaying a search result when a password is set for each category in step S6. FIG. 12 merely replaces the restricted phrase in FIG. 11 with the category to which the restricted phrase belongs, and detailed description thereof is omitted.

  Returning to FIG. 7, when the process of step S <b> 6 is completed, the information processing apparatus 1 waits for an article browsing request (S <b> 7). The article browsing request is input to the information processing apparatus 1 together with the article ID that identifies the article that the user wants to browse when the user clicks the display button shown in FIGS.

  When receiving the browsing request (S7 Yes), the information processing apparatus 1 confirms whether the article corresponding to the article ID received together with the browsing request includes a restricted phrase (S8). The processing in step S8 is performed by the information processing apparatus 1 confirming whether the confidential flag of the received article ID is ON or OFF with the intermediate data (FIG. 10A or B). If the confidential flag is ON, the article includes a restricted phrase.

  When a restriction word / phrase is included (S8 Yes), the information processing apparatus 1 confirms whether the corresponding password is input (S9). Therefore, the information processing apparatus 1 refers to the intermediate data (FIG. 10A or B), and specifies a restricted phrase or category included in the article from the received article ID. Then, the password set in the specified restricted phrase or category is acquired with reference to the password table (FIG. 4A or B). Thus, the information processing apparatus 1 can perform the process of step S9 by confirming whether the password set for the specified word or category matches the password received together with the browsing request.

  If the passwords match, the corresponding password has been input (S9 Yes), and the information processing apparatus 1 displays the content of the article on the output unit 17 (S10). Otherwise (S9 No), the information processing apparatus 1 does not display the content of the article, and displays a password mismatch on the output unit 17 (S11).

  FIG. 13 is a diagram illustrating an example of a screen for displaying the content of an article in step S10. FIG. 13 is a screen displayed when the article corresponding to the subject “subject 2” in FIG. 11 is selected and the user correctly inputs the password (“getmoney”) for the restriction word “wholesale price” included in the article. is there.

  FIG. 14 is a diagram illustrating a screen example for notifying that an article is not displayed due to a password mismatch in step S11. FIG. 14 is a screen displayed when the article corresponding to the subject “subject 2” in FIG. 11 is selected and the input of the corresponding password (“getmoney”) is not accurate.

  The return button 141 is a button that can be clicked by the user via the input unit 16. When the user clicks the return button 141, the search result of FIG. 11 or FIG. 12 is displayed, and the user can select another article or re-enter a new password.

  FIG. 15 is a functional block diagram of the information processing apparatus 1 in the embodiment of the present invention. The control unit 11 includes an article reception unit 31, a search unit 32, and a screen generation unit 33. Each functional unit of the control unit 11 is realized as a program executed by a CPU (not shown) provided in the control unit 11, but may be realized by hardware. The storage unit 13 includes an article DB 131 (see FIG. 3) and a password table 132 (see FIG. 4A or B).

  The article reception unit 31 stores articles input via the input unit 16 in the article DB 131. The state of the processing is as described in FIGS.

  The search unit 32 searches the article DB 131 based on the search condition input to the information processing apparatus 1 and acquires an article corresponding to the search condition. In addition, the search unit 32 identifies an article including a phrase (restricted phrase) that should be restricted from browsing among articles corresponding to the search condition, and outputs the article together with an article corresponding to the search condition as a search result.

  The screen generation unit 33 displays a list of article names included in the search result on the output unit 17. At this time, a password input field is added and displayed for articles including restricted words.

  In response to the browsing request input to the information processing apparatus 1, the screen generation unit 33 displays the content of the article corresponding to the article ID received together with the browsing request on the output unit 17. Furthermore, the screen generation unit 33 refers to the password table 132 when a browsing request for an article including a restricted phrase is input, and a password input via the password input field and a password associated with the restricted phrase. If "" matches, the content of the article is displayed on the display unit.

  In the above embodiment, in the search result display screen (FIG. 11 or FIG. 12), the information processing apparatus 1 cancels the browsing restriction on the article including the restricted phrase together with the list of the subject of the article included in the search result. Although the password input field is displayed, the password input field may be displayed after receiving the browsing request. Hereinafter, this case will be described as a modification.

  FIG. 16 is a flowchart showing a modification of the browsing process of the information processing apparatus in the embodiment of the present invention. The difference from FIG. 7 is that when the information processing apparatus 1 does not provide a password input field when displaying the search result and receives a browsing request, the article requested to be browsed contains a restricted phrase. The password entry field is displayed and the password entry is requested. In FIG. 16, steps that are the same as those in FIG. 7 are given the same numbers, and descriptions of the common steps are omitted.

  Also in the present modification, articles are posted in advance, and articles posted in the article DB 131 are accumulated (S0). First, the information processing apparatus 1 receives a search request for articles stored in the article DB 131 (S1). When a search condition is input to the information processing apparatus 1, the information processing apparatus 1 performs a search based on the search condition (S2).

  If there is an article corresponding to the search condition as a result of executing the search based on the search condition (S2 Yes), the information processing apparatus 1 specifies the article ID and displays the search result on the output unit 17 (S6). In this modified example, unlike FIG. 7, it is not determined whether or not the restricted word / phrase is included at this time. The search result is displayed, for example, as a list of subject names of articles corresponding to the search condition.

  FIG. 17 is a diagram illustrating an example of a screen that displays search results in the present modification. FIG. 17 shows a search result when the word “test” is entered in the keyword search field 81 of FIG. 8 as a search keyword.

  In FIG. 17, four articles corresponding to the search condition are displayed together with the subject names, and no password entry field is provided. Each displayed subject is a hyperlink. For example, when the user clicks the link 171 via the input unit 16, the browsing request is processed together with the article ID that identifies the article corresponding to the subject subject2. Input to the device 1.

  Returning to FIG. 16, if the information processing apparatus 1 executes the search based on the search condition and there is no article corresponding to the search condition (No in S <b> 2), the output unit 17 displays that the corresponding information does not exist in the article DB 131. (S3). If there is an article corresponding to the search condition (S2 Yes), after the processing in step S6 is completed, the information processing apparatus 1 waits for an article browsing request (S7).

  When receiving the browsing request (S7 Yes), the information processing apparatus 1 confirms whether the article corresponding to the article ID received together with the browsing request includes a restricted phrase (S8). The processing in step S8 is performed by the information processing apparatus 1 confirming whether the confidential flag of the received article ID is ON or OFF with the intermediate data (FIG. 10A or B). If the confidential flag is ON, the article includes a restricted phrase. When the restricted word / phrase is included (S8 Yes), the information processing apparatus 1 displays on the output unit 17 a screen requesting input of a password for releasing the browsing restriction on the article (S12).

  FIG. 18 is a diagram showing an example of a screen for inputting a password in this modification. FIG. 18 illustrates a case where the link 171 in FIG. 17 is clicked and an article browsing request corresponding to the subject “subject 2” is input to the information processing apparatus 1.

  In FIG. 18, the subject of the article requested to be browsed is “subject2”, and it is displayed that the content of this article includes the restricted word “wholesale price”. In FIG. 18, a password input field 181 for releasing the viewing restriction on the restricted word and a display button 182 for viewing the content of the article are further displayed.

  The display button 182 is a button that can be clicked by the user via the input unit 16. When the user clicks the display button 182, the password entered in the password input field 181 is input to the information processing apparatus 1.

  Returning to FIG. 16, after the processing of step S12 is completed, the information processing apparatus 1 confirms whether the corresponding password has been input (S9). The information processing apparatus 1 refers to the intermediate data (FIG. 10A or B), and specifies a restricted phrase or category included in the article from the received article ID. Then, with reference to the password table 132 (FIG. 4A or B), the password set in the specified restricted phrase or category is acquired. In this way, the information processing apparatus 1 confirms whether the password set in the specified word or category matches the password input to the information processing apparatus 1 when the display button 182 is clicked. The process of step S9 can be performed.

  If the passwords match, the corresponding password has been input (S9 Yes), and the information processing apparatus 1 displays the content of the article on the output unit 17 (S10). Otherwise (S9 No), the information processing apparatus 1 does not display the content of the article, and displays a password mismatch on the output unit 17 (S11).

  Thus, by using the information processing apparatus 1 of the present embodiment (and its modifications), it becomes possible to facilitate management of shared information and to prevent leakage of confidential information. That is, at the time of input of information to the article DB 131 (posting of articles), the information provider (contributor) inputs information to the article DB 131 without any restrictions even if the article includes regulated words. It can be carried out. The information provider does not need to determine the confidentiality level of the information and does not need to restrict access such as setting a password. It is expected to increase the amount of articles collected by posting articles without burdening the information provider.

  When the collected article is browsed, the user is automatically restricted from browsing if the restricted article is included in the requested article, and the administrator of the information processing apparatus 1 that provides the information browsing service. Information is prevented from leaking to unintended users. In addition, since the browsing restriction is canceled by inputting a password, the administrator of the information processing apparatus 1 can perform a setting to limit the browsing of articles only to a specific user.

  Which word is set as the restricted word is stored in the password table 132. Since this password table 132 can be freely set by the administrator of the information processing apparatus 1, the administrator selects a phrase to be specified as a restricted phrase or a category to which the restricted phrase belongs, and the browsing policy for shared information Can be changed flexibly. For example, by adding an anti-social phrase or the like, it is possible to prevent the anti-social content from being shown to children even if the content is freely spoken on BBS or the like.

  In addition, priority can be set for restricted words and categories. For example, if a single article contains a plurality of restricted words, if you enter a password for a restricted word with a higher priority, you can use it to remove the viewing restrictions for a restricted word with a lower priority. become.

  In the present embodiment and its modifications, search conditions and browsing requests are input via the input unit 16 provided in the information processing apparatus 1, but other information processing apparatuses connected via a network. May be input. Such a system can be constructed, for example, by connecting a plurality of information processing apparatuses equipped with a network card as the peripheral device interface 15 via a network cable.
