hiding methods become paid growing attention these days.Many systems of information hiding have been proposed as one of the technique resolving copyright problems in digital contents.In fact, almost all of existing information hiding methods are intended for images and sounds.Methods of hiding information into text proposed so far, however, processed texts as, essentially,an image.In this paper,we propose an information hiding method for text which uses text as not paper images but sequences of characters.That means that linguistic expressions are altered to hide hidden information while the meaning of the text is preserved.Our target text is written in Japanese in the field of software manual and document for user agreement of the software.Actually, this method hides information into text by paraphrasing with a dictionary which consists of pairs of expressions having the same meaning. In this paper,we report what kinds of linguistic component are suitable for hiding by paraphrasing,how to express paraphrasing rules, paraphrasing rules we propose, and the system we developed.","subitem_description_type":"Other"}]},"item_2_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"2350","bibliographic_titles":[{"bibliographic_title":"情報処理学会論文誌"}],"bibliographicPageStart":"2339","bibliographicIssueDates":{"bibliographicIssueDate":"2001-09-15","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"9","bibliographicVolumeNumber":"42"}]},"relation_version_is_last":true,"item_2_alternative_title_2":{"attribute_name":"その他タイトル","attribute_value_mlt":[{"subitem_alternative_title":"情報セキュリティ"}]},"weko_creator_id":"1"},"id":11872,"updated":"2025-01-23T01:58:03.077490+00:00","links":{},"created":"2025-01-18T22:46:23.020276+00:00"}
