We used two types of watermark methods, we embedded complex watermark. We can detect the falsification by the sensitive watermark for modification of image. On the other hand, we can maintain the patient identification information by the resistant watermark to image processing and we can know the demographic information about the institution and the patient. We developed the embedding method of watermark and the error correction method of extracted data and also can keep the image deterioration in low level. If the extracted information has 30% error data, we can repair the information completely by combined error correction method. There is a dilemma between the watermark tolerance to image processing and deterioration in image quality. We decided the suitable trade-off point and we will show the watermarked images and the new embedding/error-correction methods.","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":"RSNA'04 90th Scientific Assembly and Annual Meeting","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":"667478","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nishio, Masato"}],"nameIdentifiers":[{"nameIdentifier":"667479","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tsukamoto, Nobuhiro"}],"nameIdentifiers":[{"nameIdentifier":"667480","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Shohji"}],"nameIdentifiers":[{"nameIdentifier":"667481","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Mizuno, Yohsuke"}],"nameIdentifiers":[{"nameIdentifier":"667482","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fujii, Hirofumi"}],"nameIdentifiers":[{"nameIdentifier":"667483","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kasamatsu, Tomotaka"}],"nameIdentifiers":[{"nameIdentifier":"667484","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawaguchi, Osamu"}],"nameIdentifiers":[{"nameIdentifier":"667485","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"et.al"}],"nameIdentifiers":[{"nameIdentifier":"667486","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"安藤 裕","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"667487","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"川口 修","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"667488","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":"Impact of enhanced digital watermark in 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":"Impact of enhanced digital watermark in 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":"2004-12-06"},"publish_date":"2004-12-06","publish_status":"0","recid":"67960","relation_version_is_last":true,"title":["Impact of enhanced digital watermark in medical images - Improvement of the security by using demographic watermarked patient-ID and institution-ID"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T20:31:43.346247+00:00"}
