The proposed method can increase an amount of the embedding data. In the conventional method, the amount of the data which can be embedded in the printed image has been only 120 bits. This paper proposes two methods; one is the method which increases the number of blocks and another is the method which increases the number of codes in each block. By the experiment, it is indicated that the latter is superior to the former. In the latter method, we can increase the detection rate by determining the data bit based on the correlation with the embedding codes. By using the proposed method, 192 bits can be embedded in the printed image and we can achieve 90% of average detection rate.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"6","bibliographic_titles":[{"bibliographic_title":"研究報告 オーディオビジュアル複合情報処理（AVM）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2011-09-14","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"15","bibliographicVolumeNumber":"2011-AVM-74"}]},"relation_version_is_last":true,"weko_creator_id":"10"},"created":"2025-01-18T23:33:05.866357+00:00","id":77536,"links":{}}
