[Picture Viewer] ntt DL : 0: 本次研究主要内容是对音频信号进行数字水印加密技术的分析，数字水印技术作为保密技术的一种形式，将具有特殊含义的数据信息嵌入到数字媒体中，以达到对数字媒体进行辨识、标记和版权保护的目的。主要介绍几种水印的嵌入方法：相位法、回声法、时域方法、频域方法、小波域变换等。-Digital audio watermarking is nowadays gaining popularity among the original audio content producers. It provides a way to the owner to prove ownership by using watermark which forms integral part of audio. An approach is made in this paper to collectively introduce applications and techniques up till developed for audio watermarking.The proposedalgorithm is based on wavelet transform which has efficient computational load and also on cosine transform for increasing the watermark embedding capacity. Keywords: Watermark, audio, DFT, DCT, DWT, and DSSS.
