數位浮水印,是一種將資訊隱藏在數位內容中的技術。近年來由於數位內容被大量使用,尤其是廣泛的在網路上流傳,數位版權保護成為迫切需要被解決的問題,數位浮水印是一個解決此問題的好方法。針對數位版權保護,本論文提出一個新的方法,將平衡不對稱區塊設計編碼後加入離散小波轉換的高頻係數當中,再利用人類視覺系統的特性來控制浮水印的強度。在驗證端利用原始影像萃取浮水印後,再利用平衡不對稱區塊設計的數學結構確認數位版權資訊。而傳輸過程中由於平衡不對稱區塊設計俱備數學結構,可增加浮水印對雜訊的強健性。本方法具有不可見的特性,可在影像中夾帶資訊,因此很適合應用於秘密通訊。
Digital watermarking is a kind of technique by which information can be embedded into digital contents. In recent years, digital contents are extensively used, especially over the Internet. Digital copyright protection thus becomes a more and more serious problem. Digital watermarking may be a good solution due to its robustness and invisibility. This study aims to present a new watermarking approach base on the balanced incomplete block designs (BIBD). The watermark is embedded into the high frequency wavelet coefficients of an original image. Characteristics of human visual system are used to control the watermark strength. At the receiver site, the original image is used to extract the embedded watermark, and then the mathematical structure of the BIBD is used to identify the copyright date. Robustness is achieved by utilizing the mathematical structure of the BIBD. Because of the invisibility and big capacity of information are both satisfy, this approach is adaptable to cover communication.
