- 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(jì)算機(jī)通訊技術(shù)的發(fā)展，使數(shù)據(jù)的交換和傳輸成為一個(gè)簡(jiǎn)便的過(guò)程。但是，無(wú)限次完美的復(fù)制和通過(guò)網(wǎng)絡(luò)迅速的傳播給媒體原始擁有者的權(quán)益帶來(lái)了潛在的威脅：其艱苦勞動(dòng)的成果有可能在一夜間被無(wú)償?shù)拇笈鷱?fù)制并傳播到世界的每個(gè)角落。因此，數(shù)字媒體的版權(quán)保護(hù)成為一個(gè)迫切需要解決的問(wèn)題 。傳統(tǒng)的加密技術(shù)，如公開(kāi)密鑰（RAS）、私有密鑰（DES），能夠在數(shù)據(jù)傳輸過(guò)程中提供保護(hù)作用，但數(shù)據(jù)一旦被接收并解密，其保護(hù)作用也隨之消失。正是因?yàn)閿?shù)字形式的多媒體產(chǎn)品可以方便地復(fù)制并在網(wǎng)絡(luò)環(huán)境下廣泛傳播，大范圍的侵權(quán)拷貝行為受到了音像、出版、影視和軟件等行業(yè)的高度關(guān)注。數(shù)字水印技術(shù)可為版權(quán)保護(hù)等問(wèn)題提供一個(gè)的有效解決方法 。
