In this paper, we introduce a novel watermarking\nmethod to embed QR codes in digital images. The method is based on discrete wavelet\ntransform (DWT). The original image is divided into blocks, and QR codes are added to\nparticular bits of LL2 level coefficients of the selected block according to the visual masking\neffect of the human visual system. It has been shown that this method is robust for JPEG\ncompression and has good transparency. The embedded information can be extracted\ncorrectly even if the images are compressed to 11% of the original according to the contents\nof the images.","subitem_description_type":"Abstract"}]},"item_3_description_40":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_3_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"神奈川大学"}]},"item_3_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12068302","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1880-0483","subitem_source_identifier_type":"ISSN"}]},"item_3_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Zhang, Shanjun"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"張, 善俊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshino, Kazuyoshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉野, 和芳"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-20"}],"displaytype":"detail","filename":"02 19 3-6.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"02 19 3-6.pdf","url":"https://kanagawa-u.repo.nii.ac.jp/record/6956/files/02 19 3-6.pdf"},"version_id":"0a0fdc13-3bdd-410d-8645-bf7112e378d8"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"QR code","subitem_subject_scheme":"Other"},{"subitem_subject":"JPEG.","subitem_subject_scheme":"Other"},{"subitem_subject":"human visual system","subitem_subject_scheme":"Other"},{"subitem_subject":"discrete wavelet transform","subitem_subject_scheme":"Other"},{"subitem_subject":"watermark","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"DWT-Based Watermarking Using QR Code","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"DWT-Based Watermarking Using QR Code"}]},"item_type_id":"3","owner":"1","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-12-21"},"publish_date":"2009-12-21","publish_status":"0","recid":"6956","relation_version_is_last":true,"title":["DWT-Based Watermarking Using QR Code"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T15:44:47.609750+00:00"}
