A simple and secure watermarking protocol

The advances in multimedia and networking technologies enable copyright infringement of digital content distributed on Internet. Such infringement, particularly promoted by peer-to-peer file-sharing, causes copyright holders lost sales every year. Consequently, methods to protect digital copyright protection are needed in a global Internet environment. Watermarking protocols are recognized as a promising technique developed to address the problem of asserting authorship and determining accountability when piracy occurs. In this paper, a simple watermarking protocol purposely designed to be easily implemented in the current model of content distribution on the Internet is proposed. The protocol is secure and able to protect the digital asset of the web-based distribution and associated rights.
