Security requirements are met by security measures, which generally consist of several security mechanisms such as cryptographic mechanisms and digital watermarking techniques. In this paper, image authentication between Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT) watermarking is analyzed in performance comparison. On-line handwritten signature is acquired G-Pen F350 tablet encodes the signature which creates own signature image of different users and is used as watermark. The same digital watermarking embedding and extracting algorithms based on DCT and DWT are discussed and implemented. As in experimental results for the robustness and performance comparison, Peak Signal to Noise Ratio ( PSNR) and Normal Correlation (NC) are estimated from different standard images."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Image Authentication"}, {"interim": "cryptographic mechanism"}, {"interim": "digital watermarking"}, {"interim": "DCT"}, {"interim": "DWT"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2019-07-12"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "11091.pdf", "filesize": [{"value": "376 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 376000.0, "url": {"url": "https://meral.edu.mm/record/4952/files/11091.pdf"}, "version_id": "07d89f48-8f83-4af6-9919-8d3d3e82e000"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "", "subitem_journal_title": "Eleventh International Conference On Computer Applications (ICCA 2013)", "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": "kyaw, Mya Thidar"}, {"subitem_authors_fullname": "Soe, Kyi"}]}]}, "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": "2013-02-26"}, "item_1583159847033": {"attribute_name": "Identifier", "attribute_value": "http://onlineresource.ucsy.edu.mm/handle/123456789/851"}, "item_title": "Performance Analys is of Image Authentication between  DCT and DWT Watermarking", "item_type_id": "21", "owner": "1", "path": ["1597824273898"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000004952", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2019-07-12"}, "publish_date": "2019-07-12", "publish_status": "0", "recid": "4952", "relation": {}, "relation_version_is_last": true, "title": ["Performance Analys is of Image Authentication between  DCT and DWT Watermarking"], "weko_shared_id": -1}
