- 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.

信息媒体的数字化与计算机通讯技术的发展，使数据的交换和传输成为一个简便的过程。但是，无限次完美的复制和通过网络迅速的传播给媒体原始拥有者的权益带来了潜在的威胁：其艰苦劳动的成果有可能在一夜间被无偿的大批复制并传播到世界的每个角落。因此，数字媒体的版权保护成为一个迫切需要解决的问题 。传统的加密技术，如公开密钥（RAS）、私有密钥（DES），能够在数据传输过程中提供保护作用，但数据一旦被接收并解密，其保护作用也随之消失。正是因为数字形式的多媒体产品可以方便地复制并在网络环境下广泛传播，大范围的侵权拷贝行为受到了音像、出版、影视和软件等行业的高度关注。数字水印技术可为版权保护等问题提供一个的有效解决方法 。
