摘要 数字水印的基本功能是将产权、产品的标识码以及购买者的信息等嵌入到数字媒体中。用小波变换的方法对数字音频的水印的嵌入和提取做了仿真研究,仿真结果表明该方法是可行的。 The basic function of watermarking is to embed signs such as property right, product identification code and information of the buyers into the digital media. The embedment and extraction of digital audio watermark simulation is done based on wavelet transform. The results show its reasonableness.
