- A digital watermark algorithms based on the HVS

Digital media and computer information communication technology development to enable the exchange and transmission of data into a simple process. However, unlimited perfect reproduction and rapid dissemination through the network to the original owners and the media have brought potential threats : The results of their hard labor may be free in a night of reproduction and dissemination to the world every corner. Therefore, a digital media copyright protection an urgent need to address the problem. Traditional encryption techniques, such as public key (RAS), the private key (Des), to provide protection in data transmission process role，But once the data has been received and decryption, disappeared from its protection role. It is precisely because of the multimedia products in digital form can be easily reproduced and widely disseminated in the network environment, a wide range of infringement acts by-copy, publishing, video and software industries a lot of attention. Digital watermarks for copyright protection technology can provide an effective solution.
— 一種基于HVS的數(shù)字水印算法
信息媒體的數(shù)字化與計算機通訊技術的發(fā)展，使數(shù)據(jù)的交換和傳輸成為一個簡便的過程。但是，無限次完美的復制和通過網(wǎng)絡迅速的傳播給媒體原始擁有者的權益帶來了潛在的威脅：其艱苦勞動的成果有可能在一夜間被無償?shù)拇笈鷱椭撇鞑サ绞澜绲拿總€角落。因此，數(shù)字媒體的版權保護成為一個迫切需要解決的問題 。傳統(tǒng)的加密技術，如公開密鑰（RAS）、私有密鑰（DES），能夠在數(shù)據(jù)傳輸過程中提供保護作用，但數(shù)據(jù)一旦被接收并解密，其保護作用也隨之消失。正是因為數(shù)字形式的多媒體產(chǎn)品可以方便地復制并在網(wǎng)絡環(huán)境下廣泛傳播，大范圍的侵權拷貝行為受到了音像、出版、影視和軟件等行業(yè)的高度關注。數(shù)字水印技術可為版權保護等問題提供一個的有效解決方法 。
