| 摘 要： | 基于MP3编码中所应用的心理声学模型和感知熵(PE),对音频信号中PE值大于1800的帧进行数字水印嵌入.嵌入在频域中进行,通过叠加一个加权的随机复序列嵌入水印信息.在接收端,采用频域相关法能可靠提取嵌入数据,仅用到少量系统参数而不需要原始信号.实验表明该水印具有很好的隐蔽性,对于MP3编码表现出优良的稳健性.

| Abstract: | Based on the psychoacoustic model II and perceptual entropy (PE) used in MP3 encoding, watermark embedding is carried out by modifying the frames with PE above 1 800. By adding a random complex sequence to the spectral components in the medium and low bands in the frequency domain, a watermark is embedded. Extraction of the embedded data is achieved by using a frequency domain correlation approach without the original host signal. Experimental results show that the proposed scheme can achieve high imperceptibility and satisfactory robustness against MP3 encoding. |
