PROBLEM TO BE SOLVED: To solve such problem that a masking means is not applied to a character string, which is not registered beforehand, when masking specified information in a document. SOLUTION: The sentences of a masking object document are read one by one (203) and morpheme analysis is performed (204). Next, masking rules 81 are read in order with respect to the morpheme analyzed result (205) and it is investigated whether the result is matched to the rules or not (206). When the result matches with the masking rules, masking candidate parts are displayed (207). Next, the masking part is made to be corrected by a user (212). A document with the designated masking part is newly prepared. Finally, the masked document is newly prepared (213). |
