With a combination ofLifting Wavelet Transform (LWT) and DiscreteCosine Transform (DCT), the system is presented. Keysequences used for watermark embedding andextraction are generated by Linear CongruentialGenerator (LCG). Moreover, for the sake of securityenhancement, double coded image puzzling method iscreated. The LWT is applied to decompose theoriginal image into four sub-band images. Then theDCT is computed on the selected sub-band of the LWTcoefficients. The watermark bits are modified by LCGand embedded in the DCT transformed of the selectedLWT sub-band of the original image. The Doublecodedimage puzzling is created in order not torecognize the meaningful image by illegal users. Theproposed system mainly focuses on an invisiblewatermark embedding, imperceptibility ofwatermarked image, blind watermarking by using keysequence instead of using original image, androbustness for watermark extraction. The presentedsystem is realized in MATLAB."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value": []}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2019-07-03"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "12049.pdf", "filesize": [{"value": "347 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 347000.0, "url": {"url": "https://meral.edu.mm/record/3637/files/12049.pdf"}, "version_id": "aca4832e-196c-4125-8960-173a9cc715bb"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "", "subitem_journal_title": "Twelfth International Conference On Computer Applications (ICCA 2014)", "subitem_pages": "", "subitem_volume": ""}]}, "item_1583103147082": {"attribute_name": "Conference papers", "attribute_value_mlt": [{"subitem_acronym": "", "subitem_c_date": "", "subitem_conference_title": "", "subitem_part": "", "subitem_place": "", "subitem_session": "", "subitem_website": ""}]}, "item_1583103211336": {"attribute_name": "Books/reports/chapters", "attribute_value_mlt": [{"subitem_book_title": "", "subitem_isbn": "", "subitem_pages": "", "subitem_place": "", "subitem_publisher": ""}]}, "item_1583103233624": {"attribute_name": "Thesis/dissertations", "attribute_value_mlt": [{"subitem_awarding_university": "", "subitem_supervisor(s)": [{"subitem_supervisor": ""}]}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Tun, Amy"}, {"subitem_authors_fullname": "Thein, Yadana"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2014-02-17"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "http://onlineresource.ucsy.edu.mm/handle/123456789/137"}, "item_title": "A LWT and DCT based Blind Watermarking Scheme for Digital Images", "item_type_id": "21", "owner": "1", "path": ["1597824273898"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000003637", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2019-07-03"}, "publish_date": "2019-07-03", "publish_status": "0", "recid": "3637", "relation": {}, "relation_version_is_last": true, "title": ["A LWT and DCT based Blind Watermarking Scheme for Digital Images"], "weko_shared_id": -1}
