Research Of Digital Audio Watermarking

With the development of multi-media and network technique, the productive output of digital media is increasing. Compare with the analog media, the digital media have the advantage of editing, replicating, storing easily. And the digital media can be transmitted quickly via the network. With the application of the digital media (including the digital image, digit audio, digit video and so on) becomes widespread, the protect copyright becomes more important. Digital watermarking can work as an efficient and available way to solve copyright protection. Under the condition of keeping the characteristic of digital media, the digital watermarking was imbedded into it. The imbedded information can include copyright, some datum of researcher or user. And we can draw the digital watermarking from digital media while the copyright need to be show.This thesis introduces watermarking algorithms which the author researched on. Firstly, this paper introduces the history, the recent development and the concept of digital watermarking; secondly, this paper puts great emphasis on how to imbed digital watermarking into digital audio; finally, the main conclusions was given..
