The image processing modified the watermark information and we recovered the watermark by the error correction methods. We used the BIT-swapping method for embedding water-mark. After image processing, the detection ratio of the watermark was decreased. To correct the patient-ID and institution-ID, we used three type of methods, (1)Bose-Chandhuri-Hocquenghem code, (2)Majority correction method and (3)scramble location method. Once the detection ratio of watermark was decreased to 60%, we could recovery the watermark information. The peak signal to noise ratio was 39 dB at LSB-swapping. We think that these watermarking methods are suitable to the medical images.","subitem_description_type":"Abstract"}]},"item_10005_description_6":{"attribute_name":"会議概要（会議名, 開催地, 会期, 主催者等）","attribute_value_mlt":[{"subitem_description":"EuroPACS-MIR 2004","subitem_description_type":"Other"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Ando, Yutaka"}],"nameIdentifiers":[{"nameIdentifier":"666906","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishio, Masato"}],"nameIdentifiers":[{"nameIdentifier":"666907","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"666908","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujii, Hirofumi"}],"nameIdentifiers":[{"nameIdentifier":"666909","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawaguchi, Osamu"}],"nameIdentifiers":[{"nameIdentifier":"666910","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitamura, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"666911","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安藤 裕","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666912","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川口 修","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"666913","nameIdentifierScheme":"WEKO"}]}]},"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":"conference object","resourceuri":"http://purl.org/coar/resource_type/c_c94f"}]},"item_title":"Digital Watermark application for medical images - Improvement of the security by using demographic watermarked patient-ID and institution-ID","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Digital Watermark application for medical images - Improvement of the security by using demographic watermarked patient-ID and institution-ID"}]},"item_type_id":"10005","owner":"1","path":["28"],"pubdate":{"attribute_name":"公開日","attribute_value":"2004-09-29"},"publish_date":"2004-09-29","publish_status":"0","recid":"67894","relation_version_is_last":true,"title":["Digital Watermark application for medical images - Improvement of the security by using demographic watermarked patient-ID and institution-ID"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:32:30.076589+00:00"}
