10 ”, it is possible to control access to a specific file using the function of a WWW server that sends document data in response to a request from a WWW client.
For example, the UR of the specific file from the WWW client
When L is specified, a message prompting for a password is displayed first, and the file data is sent to the WWW client only when the password is entered correctly.

[0004]

The above-mentioned first prior art is to make it possible to refer to an HTML document on the Internet from a WWW client by designating a URL. HTML
It was possible to control access to the document.
However, in the second conventional technique, access control is performed for each file or directory, so that, for example, as shown in FIG.
In the document content 1030 displayed by the WWW client, it is not possible to make a setting such that only the information of “scheduled event in department” and “executive management system” is not permitted to be referred from a specific reference person. Therefore, in such a case, it is necessary to separately prepare a document in which these pieces of information are deleted, and to make a specific referencer specify the URL of the separately prepared document, which makes it difficult to create and manage the document. There's a problem.

The present invention has been made to solve the above inconvenience, and an object of the present invention is to provide a method for performing reference control on a part of a document without modifying the existing document.

[0006]

According to the present invention, an item in a document to be reference-controlled is set in a storage device as a reference control table for a reference-destination document and a referrer to which reference control is performed,
When the reference destination of a document is instructed, the reference control table is referred to, and when the reference destination includes the identifier and the referrer of the document set in the reference control table, the item set in the document is set. It features a document reference control method that suppresses the display of contents.

Further, when the contents of the document are searched and the reference destination embedded in the document corresponds to the document identifier and the referrer set in the reference control table, this reference destination corresponds to the document identifier and the referrer. Replace with another referenced expression that contains.

Note that it is possible to materialize a computer program including the above method as steps on a computer-readable storage medium.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings.

First, the configuration of a system for implementing the document processing method of the present invention will be described with reference to FIG. 3010
Numerals 3040 are computers such as workstations and personal computers, to which a plurality of computers are connected via a network 3050. A central processing unit 3060 controls hardware and executes programs. 3070 is a keyboard for receiving user input.
An input device such as a mouse. Reference numeral 3080 is a display device such as a display for displaying the result of document processing. 3090
Is a RAM that stores the running program and work data
It is a main storage device such as (Random Access Memory). An external storage device 3100, such as a hard disk, stores programs and document files. 31
Reference numeral 10 is a bus for transmitting data between 3060 and 3100. The external storage device 3100 stores a basic control program (OS) 3120 for controlling the entire system and a document display program 3130 for displaying document data. The components 3220 to 3270 are 3060 to 31.
The same as 10. The external storage device 3260 has a basic control program (OS) 328 for controlling the entire system.
0, a document sending program 3290 that sends document data to the document displaying program in response to a request from the document displaying program, and a part of the document data is deleted or replaced with another data and sent to the document sending program Reference A control program 3300, a reference control setting program 3310 for setting a document reference control method, a reference control definition table 3320 for storing information set by the reference control setting program, some document data 3330, and each document A template 3340 defining a format is stored. The components of 3140 to 3210 are 3060 to 313.
0 and 3220-3340 are 3350-34
70 respectively. For the operations of the document display program and the document transmission program, see "Shin Yoshimura, WW
W and information search on the Internet, UNIX MAGA
ZINE, 1994.2 ”.

Next, a display example of the document according to the embodiment will be described with reference to FIG.
Will be explained. 4010 and 4020 are examples of document display when the conventional technique is used. When the referrer A specifies the URL (http: // host1 / dir1 / doc1) of the document "Introduction of General Affairs Department", the document display example 4010 is displayed on the WWW client. Further, a document display example 4040 is displayed by designating the reference URL (http: // host1 / dir1 / doc2) of “to accounting section” described in this document. On the other hand, 4020, 4030, 4050 and 4060 are examples of document display when the method of the present invention is used. The referrer is
The reference control program name is specified as the reference destination URL, and the identifier of the referrer and the identifier of the document to be referenced are specified together as the activation parameters of the program. Eg host
When the referrer B having the identifier "SUZUKI" uses the reference control program "hide.exe" on the above 1 to display the document "Introduction of General Affairs Department" having the identifier "SOUMU", "http: / /host1/hide.exe SUZUKI SOUM
Specify "U" as the URL. As a result, for reference person B, the document in which the "internal event schedule" information has been deleted, and for reference person C, the "internal event schedule" information has been replaced with "please contact the person in charge" Is displayed.

Further, if the reference control is set also for the document indicated by "to accounting department" in which the URL is described in this document, this URL is replaced with the reference control program name, The identifier of the referrer and the identifier of the document to be referenced are added together as the startup parameters. For example, in the document display example 4020, the UR of “to accounting section”
L (http: // host1 / dir1 / doc2) to "http: // host1 / hide.
exe SUZUKI KEIRI ”. Thus, in the document display examples 4020 and 4030, the document display example 4050 in which the information of the extension numbers of the “section telephone number table” is deleted for the reference person B by referring to “accounting section” is the reference person. For C, a document display example 4060 in which the information in the “section telephone number table” is replaced with “information in the section only” is displayed. On the other hand, since the reference control is not set for the document indicated by "to the materials section" in which the URL is described in this document, the above conversion is not performed for this URL.

Next, a definition example of the document format according to the present embodiment will be described with reference to FIG. 5010 is text data, that is, document data 3330, and 5020 is a template that defines the format of this text data. Here, the text data 5010 is data composed of an arbitrary character string, and may or may not be a structured document. The template 5020 can be created by a well-known method by copying the text data 5010 and replacing the item content portion in the text data with the item name enclosed by the delimiter character string.
In the template 5020 in FIG. 4, the delimiter "<<"
As shown in the table 5030 using "and"",""IchiroSuzuki" in the text data 5010 is the item name "author", "Computer introduction" is the item name "title", and "97" is the item name "issue year". ”,“ 1 ”are defined as the item name“ issue month ”.

Next, the reference control setting program 3 shown in FIG.
The processing procedure of 310 will be described with reference to the flowchart of FIG. First, the reference control information input dialog 701
0 is displayed on the display device 3240 (step 6010),
The input of the user is accepted (step 6020).

FIG. 6 shows an example of the structure of the reference control information input dialog. The user uses the input device 3230 to input the setting information into the display areas 7020 to 7110. Area 702
In 0, an identifier for identifying the referrer of the document is designated. In the area 7030, the range for checking whether or not the document requires the reference control processing is designated by the host name. 7040
Is a table for setting information about documents for which reference control processing is performed. In the area 7060, an identifier for identifying the document for which the reference control process is performed is designated. In the area 7070, the URL of the document for which the reference control processing is performed is designated. Area 70
In 80, the URL of the template that defines the format of the document for which the reference control process is performed is designated. Reference numeral 7050 is a table for setting information on items for which reference control processing is performed. In the area 7090, the item name of the item for which the reference control processing is performed is designated. In the area 7100, a method of deleting the item, replacing it with another word or phrase, or suppressing the display is designated. Area 711
In 0, a word or phrase that replaces the content of the item is specified. Here, in the area 7100, either “delete” or “replace” is selected, and only when “replace” is selected in the area 7100, the area 711 is selected.
Input to 0 is possible.

Area 702 after the start of user input acceptance
When the setting information is input to 0 to 7110 (step 6
030), the input setting information is displayed in the area (step 6040), and the user's input is accepted again (step 6020). Also, the CANCEL button 71
When 30 is pressed (Yes in step 6050), the reference control information input dialog 7010 is hidden (step 6080), and the reference control setting program is ended.
When the OK button 7120 is pressed (step 6
060 Yes), after updating the contents of the reference control definition table according to the information set in the areas 7020 to 7110 (step 6070), the reference control information input dialog 7
010 is hidden (step 6080) and the reference control setting program ends.

FIG. 7 shows an example of the structure of the reference control definition table. The reference control definition table 8010 has a reference person identifier 8
020, pointer 8030 to the reference control document check range table 8060, reference control document information table 808
Pointer 8040 to 0, reference control item information table 8
A list of lines consisting of pointers 8050 to 120. The reference control document check range table 8060 is a list of lines including the reference control document check range 8070. The reference control document information table 8080 includes a document identifier 8090, a document URL 8100, and a template URL.
8110 is a list of rows consisting of 8110. The reference control item information table 8120 includes an item name 8130 and a replacement flag 81.
40 is a list of lines including 40 and replacement phrases 8150. Items 8020, 8070, 80 in the reference control definition table
90, 8100, 8110, 8130, 8140, 81
50 is a reference control information input dialog 7010.
Middle regions 7020, 7030, 7060, 7070, 7
Corresponding to 080, 7090, 7100, and 7110, when setting the reference control information, the value of the corresponding area is set in the table. However, regarding the area 7100, TRUE is set in the replacement flag 8140 when “replacement” is displayed, and FALSE is set in the replacement flag 8140 when “delete” is displayed.

Next, the reference control program 330 in FIG.
The processing procedure of 0 will be described with reference to the flowchart of FIG. First, the identifier of the referrer and the reference destination are acquired from the startup parameters of the program (step 9010). Next, the referrer identifier acquired from the start parameter is searched from the referrer identifier 8020 in the reference control definition table 8010, and the reference control document check range, reference control document information, and reference control item information corresponding to the referrer identifier are retrieved. It is acquired (step 9020). Next, it is checked whether the reference destination acquired from the activation parameter is a URL or a document identifier (step 9030). The URL here is the original document URL. In the case of a normal URL, since the document identifier 8090 is not registered in the reference control document information table 8080, the reference control document information cannot be acquired in step 9020. If the reference destination is a normal URL, the document pointed to by the URL is read into the buffer (step 90).
40), if it is a document identifier, template conversion processing is performed (step 9050). Thereafter, URL conversion processing is performed (step 9060), and finally, the document data in the buffer is passed to the document sending program 3290, and the processing of the reference control program ends.

Next, the processing procedure of the template conversion processing 9050 in the flowchart of FIG. 8 will be described with reference to the flowchart of FIG. First, the reference destination document identifier acquired from the start parameter is searched from the document identifier 8090 in the reference control document information table 8080, and the document URL and template URL corresponding to this document identifier are searched.
The document data and the template pointed to by are read into the buffer (step 10010). Next, a delimiter character string surrounding the item name in the template is searched, and all the item names in the template are sequentially acquired (step 1002).
0). Next, replace all the item names in the template with regular expressions that represent "arbitrary character strings," perform pattern matching between the document data and the template, and sequentially acquire the character strings corresponding to the regular expressions as the item contents. (Step 10030). For example, if the regular expression that represents an arbitrary character string is * in the example of FIG. 4, the template "copyright": << author >>"referencename" ...
When pattern matching is performed with the document data by substituting the “reference name” ..., “Ichiro Suzuki” is obtained as the item content corresponding to the item name “author”. For pattern matching using regular expressions, see "Randol
L. The first Pe by Schwartz, translated by Kayuki Kondo
rl, pp99-118, SoftBank Corp., 19
95 ". Next, the acquired item names and item contents are arranged in the order of acquisition, and a table is created in which item names and item contents in the same acquisition order are associated (step 1004).
0). Next, focusing on the first item in this table, it is checked whether the item name of this item exists in the item name 8130 in the reference control item information table (step 1005).
0), if it exists, the value of the replacement flag 8140 corresponding to this item name is further checked (step 1006).
0), if TRUE, the item content corresponding to this item name in the document data in the buffer is replaced with the character string of the replacement word / phrase 8150 (step 10070), and if FALSE, this item name in the document data in the buffer is corresponding. The item contents are deleted (step 10080). After completion of these processes, or if the item name does not exist in the table in step 10050, step 1004
It is checked whether or not the next item name exists in the table created with 0 (step 10090). If there is, the next item is focused and the process returns to step 10050. If it does not exist, the template conversion process ends.

Next, the processing procedure of the URL conversion processing 9060 in the flowchart of FIG. 8 will be described with reference to the flowchart of FIG. First, the search pointer for URL search is moved to the beginning of the document data in the buffer (step 11010). Next, the description of the URL in the document data is searched for in the range after the search pointer (step 11020), and if there is no description of the URL, the URL conversion process ends. If there is a URL description, then this URL
Is the document URL 810 in the reference control definition table 8010.
It is checked whether it exists in 0 (step 11030),
If it exists, refer to this URL as the reference control program name,
The character string that combines the referrer identifier and the document identifier is replaced (step 11040). The reference control program name is the name of the program that executes this processing (for example, the part of http: //host1/hide.exe shown in FIG. 3). Generally, in order to hide the original reference destination URL from the user, it may be replaced with another URL expression indicating the reference destination including the referrer identifier and the document identifier. If this URL does not exist in the document URL 8100 in the reference control definition table 8010,
Further, the host name of this URL is the reference control definition table 8
It is checked whether or not it is in the reference control document check range 8070 in 010 (step 11050), and if it is present, this URL is converted to a character string that combines the reference control program name, the referrer identifier, and the document URL before replacement. Replace (step 11060). That is, even if this URL is not in the reference control document, if it is a document in the host of the reference control document check range, the document indicated by the URL included in the document may be the reference control document. To be Therefore, URL conversion is performed so that reference control processing can be continuously performed within a specific host. URLs pointing to other hosts that are not within the document check range are presented to the user as the original URLs. After the above processing, the search pointer is moved immediately after this URL (step 1107).
0), the description of the URL in the document data is searched again for the range after the search pointer (step 1102).
0).

As described above, in the above embodiment, the document data and the document display program are described as being distributed to the external storage devices in a plurality of computers connected by the network.
All programs, tables and documents may be stored in an external storage device in one computer. FIG. 11 shows an example of the system configuration in that case. Each component shown in FIG. 11 is the same as the component shown in FIG. The reference control program 12090 sends data to the document display program 12080 without going through the document sending program.

In the above embodiment, the reference control document check range for designating the range for checking whether the document needs the reference control process is specified by the host name.
You may specify not only the host name but also the directory name and file name as the check range. In this case, in step 11050, it is checked whether the URL described including the directory name and the file name is within the reference control document check range.

Further, in the above embodiment, the template in which the item content in the document is replaced with the item name enclosed by the delimiter character string is used as a means for designating the item content for performing the reference control in the document. By specifying the number of characters at the start and end positions and the character string that becomes the heading item before and after the item content, it is also possible to specify the item content for which the reference control in the document is performed using a well-known method. Is.

In the above embodiment, the personal name is used as the reference identifier, but the name of the group to which the user belongs may be set instead of the personal name.

Further, in the present embodiment, the document format is defined by the template in which the item contents in the document are replaced with the item names enclosed by the delimiter character strings. However, the same data including the item name exists in the template a plurality of times consecutively. In that case, a definition indicating that the data repeatedly appears may be described in the template.

In this case, an example of the definition of the document format by the template is shown in FIG. The text data 13010 includes names of three people and extension information. In the template 13020 in FIG. 12, “{” representing repetition is shown.
And “} repeat”, as shown in the table 13030, “Ichiro Suzuki” in the text data is the item name “name [1]”, “1234” is the item name “extension [1]”, “Jiro Sato”. "Is the item name" Name [2] ",
"5678" is the item name "extension [2]", "Saburo Yamada"
Is defined as the item name “name [3]”, and “9876” is defined as the item name “extension [3]”.

At the time of template conversion processing, step 1
Instead of the processing of 0010 to 10040, the processing of steps 14010 to 14120 of FIG. 13 is executed. First, the reference destination document identifier acquired from the start parameter is searched from the document identifier 8090 in the reference control document information table 8080, and the document URL and the document and template indicated by the template URL corresponding to this document identifier are read into the buffer ( Step 14010). Next, a delimited character string surrounding the item name in the template is searched to acquire all the item names in the template (step 14).
020). At this time, the character string indicating the repetition in the template is also searched at the same time, and the item name indicating the repetition is added and acquired. Next, pattern matching is performed by replacing all the item name parts and repeating parts in the template with regular expressions representing "arbitrary character strings", and character strings corresponding to the regular expressions are sequentially acquired as item contents (step 1
4030). Next, the acquired item names and item contents are arranged in the order of acquisition, and a table (hereinafter referred to as an item extraction table) in which item names and item contents having the same acquisition order are associated with each other is created (step 14040). Next, focusing on the first item in this table, it is checked whether or not the item name of this item indicates repetition (step 14050). If it is repetition, a delimiter character string surrounding the item name for the corresponding item contents. Is retrieved and all item names are acquired (step 14060). Next, the counter n is set to 1, the search pointer is moved to the beginning of the item content corresponding to the repetition, and an empty table (hereinafter referred to as the repeated extraction table) is prepared (step 14070). Next, all the item name parts in the item contents are replaced with regular expressions representing "arbitrary character strings" to perform pattern matching, and it is checked whether or not a character string corresponding to the regular expressions exists (step 14080). If it exists, the character string corresponding to the regular expression is sequentially acquired as the item contents, and the item name and the item contents to which the counter value is added are arranged in the order of acquisition respectively. (Step 14090). Next, 1 is added to the counter n, the search pointer is moved to the position immediately after the acquired character string (step 14100), and pattern matching is performed again (step 14080). If the character string corresponding to the regular expression does not exist in step 14080, the item name and item content of interest in the item extraction table are repeatedly replaced with the item name and item content in the extraction table (step 14110). Next, it is checked whether or not the next item name exists in the item extraction table (step 14120), and if it exists, the next item name is focused and the step 140 is executed again.
Return to 50. If it does not exist, the process ends.

By this processing, when data having the same character string other than the item name and the item contents exists in one document data a plurality of times in succession, a template can be defined even if the number of repetitions is indefinite. . Further, even if the number of repetitions in the document data increases or decreases after defining the template, the template does not need to be modified.

[0029]

As described above, according to the present invention, it is possible to suppress the reference of a part by setting the part of the document in which the reference is not permitted for each referrer. By this method, it is possible to control the reference of a part of the document according to the referrer without modifying the existing document.
