ABSTRACT
The digital watermarking technology LcpdXfia! To ap/cio npoEtevoryq rr\q avacpopdq 8EV pp£0nK£. has become the focus of research in multimedia security now. Watermarking technology embeds marking information into redundancy of digital multimedia data permanently without affecting the value of commerce practice. There are several performances of watermarking technology: transparency, robustness, and security. Transparency means that watermarks should not disturb practical value of cover; robustness means the watermarked data could resist conventional manipulate; security means the watermarked data could resist hostile attacks. There are different sorts of watermarking technology based on applications: robust watermark, semi-fragile watermark, fragile watermark. The studying aim of this paper is robust audio watermark algorithm.
