Abstract

By using an dictionary for non-disclosure which manages non-disclosure character strings and non-disclosure reasons, and a forced disclosing dictionary for managing forcedly the disclosed character strings and forcedly disclosing reasons, disclosing tags, disclosing reasons, non-disclosure tags, reasons for disclosing, forcedly disclosing tags, and forcedly disclosing reasons are embedded in a document, and a character string assigned with an disclosing tag is replaced with a meaningless character string.

This configuration makes it possible to perform operations even if information which should be hidden and information which should not be hidden are not known when a document to be made public is created, causing the burden of a user to be reduced. A user can know the reason why the information which is not made public has not been made public. Even when information which is generally not made public is made public, the user can know the reason.

Claims

1. A computer-readable recording medium recorded with an information disclosure program for disclosing selected parts of a document to be made public, the program comprising the steps of:

locating at least one character string of non-disclosure in the document by referring to an auxiliary storage unit storing a dictionary which contains said at least one character string of non-disclosure in association with at least one corresponding reason;

embedding a tag and the reason of non-disclosure corresponding to the character string in the document; and

replacing the character string to which the tag of non-disclosure is given to a meaningless character string, when the document is accessed.

2. A computer-readable recording medium recorded with an information disclosure program according to claim 1 wherein said dictionary further contains at least one character string of compulsory disclosure associated with at least one corresponding reason, the program further comprising the steps of:

locating the tag of non-disclosure in the document and determining if the character string corresponding to the tag of non-disclosure matches the character string of compulsory disclosure by referring to said dictionary; and

replacing the retrieved tag of non-disclosure with the tag for compulsory disclosure, and the retrieved reason of non-disclosure with the reason for compulsory disclosure, when the character string of non-disclosure corresponding to the retrieved tag is found in the said dictionary.

3. An information disclosure apparatus for disclosing selected parts of a document to be made public, comprising:

an auxiliary storage unit storing a dictionary which manages a character string of compulsory disclosure attaching with its corresponding reason;

a means for retrieving the character string of non-disclosure from an original document referring to the dictionary registered in the auxiliary storage unit;

a means for embedding the tag and the reason of non-disclosure corresponding to the character string in the document; and

a means for replacing the character string which the tag of non-disclosure is given to a meaningless character string.

4. An information disclosure apparatus according to claim 3 for compulsorily disclosing the said non-disclosing parts of the document to be made public, comprising:

an auxiliary storage unit as a dictionary which manages a character string of compulsory disclosure attaching with its corresponding reason;

a means for retrieving the said tag for non-disclosing in the document, while collating the said dictionary for the compulsory disclosure; and

a means for replacing the retrieved tag of non-disclosure with the tag for compulsory disclosure, and the retrieved reason of non-disclosure with the reason for compulsory disclosure, when the character string of non-disclosure corresponding to the retrieved tag is found in the said dictionary.

5. A method for disclosing selected parts of a document to be made public, comprising the steps of:

locating at least one character string of non-disclosure in the document by referring to an auxiliary storage unit storing a dictionary which contains said at least one character string of non-disclosure in association with at least one corresponding reason;

embedding a tag and the reason of non-disclosure corresponding to the character string in the document; and

replacing the character string to which the tag of non-disclosure is given to a meaningless character string, when the document is accessed.

6. A method according to claim 5 for compulsorily disclosing the said non-disclosing parts of the document, comprising the steps of:

locating the tag of non-disclosure in the document and determining if the character string corresponding to the tag of non-disclosure matches the character string of compulsory disclosure by referring to said dictionary; and

replacing the retrieved tag of non-disclosure with the tag for compulsory disclosure, and the retrieved reason of non-disclosure with the reason for compulsory disclosure, when the character string of non-disclosure corresponding to the retrieved tag is found in the said dictionary.
