DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document browsing system, such as an in-house document browsing system or a WWW document browsing system, in which a plurality of users can register and browse a document. The technology relates to the processing of publishing by processing the letter in accordance with the character.

[0002]

2. Description of the Related Art Conventionally, for example, in a groupware system or a WWW-based document browsing system to which a user authentication function is added, whether a document can be browsed depends on the document viewer or the organization to which the document viewer belongs. By disclosing the document only to users who can view it, and not allowing other users to view the document, the infringement of privacy information was avoided.

[0003]

In the prior art,
Because it is only necessary to allow or disallow the browsing of the document by the viewer, for example, the entire document is disclosed or the privacy-related part of the document according to the organization of the document creator and the organization of the document viewer. To publish. The present invention solves such a problem of the prior art that a document cannot be disclosed in detail, such as not publishing, and a document creator or a reader in an in-house document browsing system or a WWW document browsing system. The purpose is to realize the publication of detailed documents according to the requirements.

[0004]

According to the present invention, there is provided a document browsing system in which a plurality of terminals are connected to a document browsing server via a network, wherein the document browsing server includes a predetermined condition such as a hidden organization or a post. Based on the above, release the document which converted the privacy information in the browsing target document to the plain text to specific document viewers, and release the browsing target document as it is to other document viewers I do.

[0005] In one embodiment of the present invention, a document registrant and a reader are authenticated, and their organizations are specified.
At the time of document registration, user information (registrant information) such as the organization to which the registrant belongs is stored in association with the registered document. When browsing a document, the user information (viewer information) such as the organization to which the browser belongs is compared with the registrant information of the document to be browsed, and the browsed document is released as it is, or the privacy information in the document is transmitted. Decide whether to publish the converted document.

In another embodiment of the present invention, authentication is performed for a document viewer, the organization to which the document belongs, etc. is specified, and the organization, etc. to which the character is to be hidden is specified by the registrant (creator). I do. At the time of document registration, information such as an organization and a post designated by the registrant (print destination information) is stored in association with the registered document. When browsing the document, the user information (viewer information) such as the organization to which the viewer belongs, the position, etc. is compared with the hidden information of the document to be browsed, and the browsed document is disclosed as it is or privacy related to the document. Decide whether to publish a document in which the information is converted to plain text.

[0007] The timing of creating a document in which the privacy-related information in the document to be viewed is converted into a hidden character can be set either when browsing the document or when registering the document. In addition, the hidden character processing is realized by replacing the proper noun part of the information on privacy in the browsing target document with a symbol, an alphabet character, or an initial document.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. In the following, an in-house document browsing system will be described as an example. However, the present invention can be widely applied to a document browsing system based on WWW and other document browsing systems in which a plurality of users can share and browse documents.

[Overall System Configuration] FIG. 1 shows the overall configuration of a document browsing system according to the present invention. In FIG.

Document browsing server 100 via a network 120 such as
It is connected to the. A user requests registration or browsing of a document to the document browsing server 100 via the network 120 by the terminal 110. Document browsing server 100
Registers a document sent from the terminal 110 as a document file in the case of a document registration request, and transmits the document file to the terminal 110 in the case of a document browsing request. As will be described later, when there is a document browsing request, the document browsing server 100 publishes the requested document as it is or publishes a document in which privacy-related information in the document has been converted into a hidden character, according to predetermined conditions. To do it.

FIG. 2 shows an overall processing flow of the document browsing server 100. The document viewing server 100
When a document registration or browsing request is received from the terminal 110 (step 201), a request for input of a user name and password is made to the terminal 110 side (step 202), and a user name and password is received from the terminal 110 side. (Step 203), this is checked against a previously registered user name and password, and it is confirmed whether the user is a valid user (Steps 204 and 205). Note that the terminal 110 may transmit the user name and password to the document browsing server 100 at the same time when a document registration / browsing request is made. When the user is authenticated, the document browsing server 100 determines the request type (step 206), and in the case of a document registration request, registers the document from the terminal 110 in the server 100 (step 207). In the case of a document browsing request, the requested document file is transmitted to the terminal 10 (step 208).

The present invention particularly relates to a document registration process and a document browsing process. Hereinafter, the document registration process and the document browsing process will be described in detail for each embodiment.

[Embodiment 1] In this embodiment, when a person other than the organization of the document registrant (document creator) views the document,
This is an embodiment in which a document in which privacy-related information in the document is converted into a hidden character is made public, and the document converted into a hidden character is created when the document is released.

FIG. 3 is a basic configuration diagram of the document browsing server 100 according to the first embodiment. This document viewing server 100
Are registered unit 310, browsing unit 320, authentication database 3
30 and an original text database 340. The registration unit 310 includes an authentication processing unit 311 and a registration processing unit 312,
The browsing unit 320 includes an authentication processing unit 321, a public processing unit 322,
It has a hidden character conversion processing unit 323. Note that the authentication processing units 311 and 321 may be the same. The authentication database 330 stores user information such as a user name, a password, an organization code, and a post code for each user (employee). The original text database 340 stores a document ID, a file name, an organization code of a registrant (creator), a document title, and the like. The document itself (original file)
Either a method of storing the original text database 340 or a method of storing the original document database 340 in another document database (not shown) is possible.

FIG. 4 is a detailed flowchart of the document registration process (step 207 in FIG. 2) in the first embodiment. After the authentication of the registration requester, the terminal 110 transmits the document file to be registered and the document title to the document viewing server 100. The registration unit 310 of the document browsing server 100 receives the document file and the document title (Step 40).
1), pass it to the registration processing unit 312. On the other hand, the authentication processing unit 31
In step 1, when the registration requester is authenticated, the organization code of the registration requester (document creator) is acquired from the authentication database 330 using the registration requester name (user name) as a key (step 402), and the registration processing unit Hand over to 312. Registration processing unit 312
Generates a document ID unique to the document file (step 403), and stores the document ID,
Register the document file name, organization code, document title, etc. and save the document file (step 40)
4). When the registration process is completed, the registration unit 310 transmits the document ID and the registration completion to the terminal 110 of the registration requester (Step 405).

FIG. 5 is a detailed flowchart of the document browsing process (step 208 in FIG. 2) in the first embodiment. The browsing unit 320 of the document browsing server 100 activates the authentication processing unit 321 again after authentication of the browsing requester. The authentication processing unit 321 acquires the organization code of the browsing requester from the authentication database 330 using the browsing requester name (user name) as a key (step 501), and passes it to the disclosure processing unit 322.
The disclosure processing unit 323 acquires a document title and a document ID that can be browsed from the original text database 340 based on the organization code of the browsing requester (step 502).
In step 20, a list of the acquired document titles is generated and transmitted to the terminal 110 of the browsing requester (step 503).

The terminal 110 displays a list of document titles sent from the document browsing server 100, and when the browsing requester selects a desired document title from the document title list, the corresponding document ID is sent to the document browsing server 100. Send.

The browsing unit 320 of the document browsing server 100
The document ID of the browsing request transmitted from the terminal 110 is received (Step 504), and is passed to the disclosure processing unit 322. The disclosure processing unit 322 obtains the organization code and file name of the document ID from the original text database 340 using the document ID of the browsing request as a key (step 505), and the organization code of the browsing requester obtained in step 501. It is determined whether or not the organization code of the browsing request document (organization code of the document creator) is equal (step 506). If the organization codes are the same, the disclosure processing unit 322 uses the document ID or the file name to retrieve a document file (original file) from the original database 340 or another document database.
Is read and transmitted to the viewing requester's terminal 110 by the viewing unit 320 (step 507).

On the other hand, if the organization code of the browsing requester does not match the organization code of the browsing request document (organization code of the creator of the document), the disclosure processing unit 322 reads the document file and then converts it into the hidden character conversion processing unit. 323 is started, and the document file is passed (step 508). The hidden character conversion processing unit 323
In step S509, a hidden character processing process of converting information such as a proper noun part relating to privacy in the document into a hidden character is performed, and the document file subjected to the hidden character processing is returned to the disclosure processing unit 322 (step 509). The browsing unit 320 receives the document file that has been subjected to the print processing from the disclosure processing unit 322, and transmits it to the terminal 110 of the browsing requester (step 510).

If the organization codes do not match, the disclosure processing unit 322 passes the document ID and file name to the hidden character conversion processing unit 323, and the hidden character conversion processing unit 323 reads the corresponding document file from the original database 340 or the like. Alternatively, the characters may be processed to be handwritten and passed to the browsing unit 320.

Next, a specific operation example of the first embodiment will be described. FIG. 6 shows a specific example of a data structure used in the first embodiment and each embodiment described later. In FIG. 6, (a), (c), and (d) relate to the first embodiment. However, the post code in the authentication database of FIG. 6C is not used in the first embodiment.

FIG. 7 shows an operation example in the case where Mr. Nakamura of the sales department registers a document file "ABC" (title: Acquisition of system order). The document browsing server 100 is a terminal 1
Upon receiving the document registration request from the 10 side, the terminal 110 requests the user to input a user and a password, and the terminal 110 transmits the user name “Nakamura” and the password “CCCC” to the document viewing server 100. The document browsing server 100 checks whether the user name “Nakamura” and the password “CCCC” are registered in the authentication database 330. Since the user name “Nakamura” and the password “CCCC” are registered in this example (FIG. 6C), the authentication OK is sent to the terminal 110 side. Return to In response to this, the terminal 110 transmits the document file “ABC” to be registered and the document title “acquire system order” to the document browsing server 100.

When the document browsing server 100 receives the document file and the document title to be registered from the terminal 110 side, the document browsing server 100 first uses the already obtained user name “Nakamura” as a key to authenticate the document from the authentication database 330 as shown in FIG. ), The organization code “002” (sales department) is acquired. Next, a document I unique to the document file “ABC” to be registered
D “0003” is generated, and the document ID “0003”, the document file name “ABC”, the organization code “002”, the document title “acquire system order”, etc. are added to the original database 340, and the document file (original file) is added. Save. The source file is stored in the source database 34

The terminal 110 transmits the user name "Sato" and the password "AAAAA" to the document browsing server. Send to 100. The document browsing server 100 checks whether the user name “Sato” and the password “AAAAA” are registered in the authentication database 33. Since the user is registered in this example (FIG. 6C), the authentication OK is sent to the terminal 110 side. Return to Next, based on the user name “Sato”, the document browsing server 100 reads the authentication database 330 from FIG.
As shown in (c), organization code "001" (General Affairs Department)
To get. Then, based on this organization code “001”, the request source (general affairs department) acquires a document title and a document ID that are likely to be of interest from the original text database 340, and transmits a list of document titles to the terminal 110 side. If the number of registered documents is small, the original text database 34
Alternatively, a list of all document titles of 0 may be transmitted.

The list of document titles is displayed on the display of the terminal 110, and it is assumed that the browsing requester (Sato) selects "acquire system order" from the list of document titles. In response, the terminal 110 transmits the document ID “0003” of the document corresponding to the title to the document viewing server 100.

The document browsing server 100 stores the document ID “00”

Upon receiving the document registration request from the terminal 110, the document browsing server 100 requests the terminal 110 to input a user name and a password. The terminal 110 transmits the user name “Nakamura” to the document browsing server 100. Send the password "CCCC". Document browsing server 100
Checks whether the user name “Nakamura” and the password “CCCC” are registered in the authentication database 1530, and returns the authentication OK to the terminal 110 because it is registered in this example (FIG. 6C). In response, the terminal 110 side:
The document file “ABC” to be registered, the document title “acquisition of system order”, and the underprint destination information “002Z, 00”
1XY ”to the document viewing server 100. here,
As shown in FIGS. 6A and 6B, the abbreviation destination information “002Z, 001XY” is based on the sales department (002), the human being of the flat employee (Z), and the department is the general affairs department (001). X) and the section manager (Y), the document file "AB
"C" is to be published with a lowercase character.

The document browsing server 100 sets a unique document ID “000” for the document file “ABC” to be registered.
3 is generated, and the document ID “0003”, the document file name “ABC”, and the surplus character destination information “002Z, 001XY” are added to the surplus character destination database 1550. Further, the document browsing server 100 adds the document ID “0003”, the document file name “ABC”, the document title “acquire system order” and the like to the original text database 1540, and stores the document file (original text file) “ABC”. The storage location of the original text file may be the same as or different from the original text database 1540. In any case, a link is provided by a document ID or a document file name. After registration, the document browsing server 10
0 returns the registration completion notification and the document ID “0003” to the terminal 110 that has issued the registration request. Document file "ABC"
Are as shown in FIG. 9A.

FIG. 19 shows an operation example when Mr. Sato of the General Affairs Department browses the document file "ABC" registered by Mr. Nakamura of the Sales Department. When receiving the document browsing request from the terminal 110, the document browsing server 100
Requests the user to enter a user name and password,
Sends the user name “Sato” and the password “AAAAA” to the document browsing server 100. The document viewing server 100
It is checked whether the user name “Sato” and the password “AAAAA” are registered in the authentication database 1530, and since they are registered in this example ((c) in FIG. 6), the authentication OK is sent to the terminal 1
Return to 10 side. Next, based on the user name “Sato”, the document browsing server 100 outputs the organization code “001” (general affairs department) and the post code “X” (see FIG. 6C) from the authentication database 1530. Department manager). Then, based on the organization code “001” and the post code “X” of the browsing requester (Sato), the original text database 1540 is created.
And obtains a document title and a document ID that are likely to be of interest to the requester (general manager in the general affairs department), and transmits a list of document titles to the terminal 110 side. When the number of registered documents is small, a list of all document titles in the original text database 1540 may be transmitted.

The list of document titles is displayed on the display of the terminal 110, and it is assumed that the browsing requester (Sato) selects "acquire system order" from the list of document titles. In response to this, the terminal 110 transmits the document ID “0003” corresponding to the document title to the document viewing server 100.

The document browsing server 100 stores the document ID “00”
When receiving “03”, using the document ID “0003” as a key, it acquires the hidden character information (one or a plurality of sets of the organization code and the post code) and the document file name of the document from the hidden character database 1550. Here, from the operation example of FIG. 18, “002Z” (a flat employee in the sales department) is used as the forehead information.
And "001XY" (General Manager, Section Manager). The document browsing server 100 sets the organizational post code “001X” (director in the general affairs department) of the browsing requester (Sato) to be the hidden character information “002Z, 001” targeted in the document “ABC”.
XY). Since the document is included in this example, the document file (original file) “ABC” having the document ID “0003” and the file name “ABC” is read out, and then the privacy-related information in the document is subjected to the hidden character processing.
The document file “ABC” that has been subjected to the hidden character processing is transmitted to the terminal 110 side. The document file “ABC” that has been subjected to the lowercase processing is as shown in FIG. 9B.

[Embodiment 4] In the present embodiment, similar to the above-described Embodiment 3, when a person in the organization and post designated by the document registrant (document creator) views the document, the privacy in the document is read. This is an embodiment in which a document in which the information related to the character is converted into a hidden character is disclosed, and the document converted into the hidden character is created in advance at the time of document registration.

FIG. 20 is a basic configuration diagram of the document browsing server 100 according to the fourth embodiment. This document viewing server 100
Is composed of a registration unit 2010, a browsing unit 2020, a secret character destination database 2030, an original text database 2040, a secret character database 2050, and an authentication database 2060. The registration unit 1010 includes an authentication processing unit 2011, a registration processing unit 2012, and a hidden character conversion processing unit 2013. The browsing unit 2020 includes an authentication processing unit 2021 and a disclosure processing unit 202
Two. The structures of the hidden character destination database 2030, the original text database 2040, and the authentication database 1050 are the same as those of the third embodiment, and the secret character database 2050 is the same as that of the second embodiment (for example, FIG.
(F)). The document file (original text file) is held in the original text database 2040 or is held in another document database or the like. Similarly, the document file that has been subjected to the print processing (the print document file) is also stored in the print database 20.
50 or another hidden character document database.

FIG. 21 is a detailed flowchart of the document registration process (step 207 in FIG. 2) in the fourth embodiment. 21, steps 2101 to 2104 are the same as steps 1601 to 1604 in FIG.
The registration processing unit 1012 determines in step 1604 the document ID,
Document file name, document title, etc.
040, and saves the document file (original text file).
The original document is passed along with D, the document file name, and the document title name (step 2105). Abbreviated character conversion processing unit 2013
Converts the information related to privacy in the original document into a hidden character (step 2106), and generates a document ID of the processed document (a hidden document ID) (step 210).
7) Register the original document ID, the hidden document ID, the document title, the document file, and the like in the hidden database 2050, and save the processed hidden document file (step 21).
08). After that, the registration unit 2010 transmits the document ID and the registration completion to the terminal 110 of the registration requester (step 2109).

FIG. 22 is a detailed flowchart of the document browsing process (step 208 in FIG. 2) according to the fourth embodiment. In FIG. 22, steps 2201 to 2205 are the same as steps 1701 to 1707 in FIG.
The difference from FIG. 17 is the processing when the organization code and the post code of the browsing requester are included in or coincide with the organization code and the post code of the print destination information of the browsing request document. If the organization code and the post code of the browsing requester are included in or match with the organization code and the post code of the print destination information of the browsing request document, the disclosure processing unit 2022 determines the document ID of the browsing request.
With the key as the key for the document ID from the database 2050,
The document file name is acquired, the hidden document file already stored at the time of registration is read, and the hidden document file is transmitted to the viewing requester terminal 110 by the browsing unit 2020 (step 2208).

The operation example of the fourth embodiment is basically the same as the combination of the second embodiment and the third embodiment, so that the illustration is omitted.

Next, an example of the configuration of the hidden character conversion processing unit used in each embodiment will be described. FIG.
FIG. 3 is a block diagram of an embodiment of a hidden character conversion processing unit. In FIG. 23, the hidden character conversion processing unit 2300 functionally includes an extraction unit 2310 that extracts a proper noun part related to privacy information from an input document (a document to be processed), and a proper noun related to privacy information extracted by the extraction unit 2310. A processing unit 2320 that performs a letter-shaped processing so that a part cannot be specified.
Divided into modules. The extraction unit 2310 extracts a proper noun part based on the morphological information analyzed by the morphological analysis unit 2311 by morphological analysis of the input document with reference to the word dictionary 2330, and also extracts the suffix table 2340. It comprises a proper noun extraction unit 2312 for referring to and acquiring the type of the social attribute or personal attribute of the proper noun part. The processing unit 2320 refers to a symbol processing unit 2322 that replaces the extracted proper noun part with a symbol, an alphabet character processing unit 2323 that replaces the extracted proper noun part with alphabetic characters, an initial character table 2360, and the like. Initial character processing unit 232 for replacing proper noun parts with the initial characters
4 and a processing selection unit 2321 that selects each processing unit 2322, 2323, or 2324 with reference to the hidden character processing table 2350.

FIG. 24 is a schematic flowchart of the operation of the present embodiment. Hereinafter, the hidden character conversion processing operation of FIG. 23 will be described with reference to FIG. First, the extraction unit 2310 reads a document to be processed (digitized document) into a memory (RAM) or the like (step 2401). The morphological analysis unit 2311 of the extraction unit 2310 refers to the word dictionary 2330, divides the input document into words, and acquires morphological information such as reading of each word, part of speech, and inflected forms (step 24).
02). In this morphological analysis, attributes of parts of speech are also obtained, and for proper nouns, social attributes, personal attributes, and the like are also obtained.

Next, the proper noun extracting unit 2312 checks whether the proper noun exists based on the obtained morphological information, and if there is, the partial character string including the proper noun is converted into the privacy information. Recognize the character string as having a possibility of infringing, and set it as a partial character string to be processed (step 240
3). For example, a flag is added to the extracted character string to be processed to distinguish it from other character strings. Further, the proper noun extracting unit 2312 includes a suffix table 2340
With reference to, further specific types of social attributes and personal attributes such as “company name”, “city name”, and “person name” are acquired for the extracted partial character string to be processed. FIG. 25 shows an example of the suffix table 2340. The morphological analysis unit 231
1 is a suffix table 2340 during the morphological analysis process.
, Refer to the proper nouns as "company name", "city name", "person name"
And so on.

In the processing section 2320, first, the processing / processing selection section 2321 checks whether or not a character string to be processed has been extracted in the document (step 240).
4). This is determined by, for example, whether a flag is added to the character string. If the partial character string to be processed has not been extracted, the processing is terminated without doing anything.

On the other hand, if the partial character string to be processed has been extracted, the processing selection unit 2321 refers to the hidden character processing table 2350 and checks the social attributes and personal Depending on the type of the attribute
Alternatively, the character processing unit 2322, the alphabet character processing unit 2323, or the initial character processing unit 2324 is uniquely selected regardless of the type (step 2405).

FIG. 26 shows an example of the hidden character processing table 2350. The processing / processing selection unit 2321 refers to the hidden character processing table 2350. For example, when the type of the processing target partial character string is “company name” in the social attribute, the symbol processing / processing unit 2322 is selected. In the case of "city name", the initial character processing unit 2324 is selected, and in the case of "person name" in the personal attribute, the alphabet character processing unit 2323 is selected. The “priority processing” column is used when selecting one of the hidden character processing methods regardless of the type of the processing target partial character string. For example, a column corresponding to “symbol processing” in the priority processing column may be used. If there is a “〇” mark, the processing / processing selecting unit 2321 uniquely selects the symbol processing / processing unit 2322 regardless of the type of the processing target partial character string.
As shown in FIG. 26, the user can freely set the correspondence between the type of the processing target partial character string and the hidden character processing method, the necessity of priority processing, and the like.

Returning to FIG. 24, when the symbol processing section 2322 is selected in step 2405, the symbol processing section 23 is selected.
In step 22, the proper noun part of the partial character string to be processed is replaced with a symbol such as "XX", "OO" or "□□".
For example, symbol processing is performed such that "Musashino Telegraph and Telephone Corporation" is changed to "XX company" (step 2406). The user can freely set what symbols to use.

Similarly, when the alphabet character processing unit 2323 is selected in step 2405, the alphabet character processing unit 2323 applies “A”, “B”, “B” to the proper noun part of the partial character string to be processed. The character string is replaced with an alphabetic character such as "C", and alphabetical character processing is performed such that "Dentaro" becomes "Mr. A" (step 2407). Also in this case, the user can freely set the alphabet characters to be used.

Similarly, when the initial character processing unit 2324 is selected in step 2405, the initial character processing unit 2324 sets the initial character table 236.
0, the proper noun portion of the partial character string to be processed is replaced with initial characters such as "M", "O", "M.K" of the proper noun, for example, "Musashino City, Tokyo" Is subjected to initial character processing such as "M city in Tokyo" (step 2408). FIG. 27 shows an example of the initial character table 2360. Initial character processing unit 2
324 searches the initial character table 2360 from the reading information of the proper noun, and converts the proper noun to the corresponding initial character.

Lastly, the processing unit 2320 overwrites the original document with the document in which all character strings to be processed have been subjected to the hidden character processing (step 2409). In this way, a document in which the privacy information can be violated is automatically created.

Although the embodiments of the present invention have been described above, it is needless to say that the present invention is not limited to the embodiments described above. For example, in Embodiments 1 and 2, as in Embodiments 3 and 4, depending on the organization and position,
It is also possible to decide whether or not to publish the text that has been turned over. Further, the present invention is not limited to an in-house document browsing system, but can be similarly applied to a WWW document browsing system and the like. In this case, the present invention is not limited to an organization or a post, but corresponds to a user, for example. It is only necessary to decide whether to publish the original document as it is or to publish the document that has been processed in print.

A program for causing a computer to execute a document registration processing procedure, a document browsing processing procedure, and a hidden character conversion processing procedure is stored in a computer-readable recording medium (FD, CD-ROM, MO, etc.) in advance.
It is also possible to record and provide it. By installing the program recorded on this recording medium into a computer, the intended function of the document browsing server as described in each embodiment is achieved. Note that this type of program may be preinstalled on a computer.
