摘要

提出了一种性能优越的自适应混合域数字音频水印嵌入算法

首先将原始数字音频划分成音频数据段;然后选取巴克码作为同步码

并在时域内将同步码嵌入到音频段的前部分;最后对音频段后部分实施DWT和DCT

并采用量化调制策略将水印信息嵌入到频域系数中。实验结果表明

该算法对常规信号处理与去同步攻击均具有较好的顽健性。

Abstract

A new robust digital audio watermarking against desynchronization attack using DWT and DCT was proposed.Firstly

the origin digital audio was segmented and then each segment was cut into two sections.Secondly

with the spa-tial watermarking technique

synchronization code was embedded into the first section.Finally

the DWT and DCT were performed on the second section

and then the watermark was embedded into the low frequency components by quantiza-tion.Experiment results show that the proposed watermarking scheme is inaudible and robust against various signal processing such as noise adding

re-sampling

re-quantization

random cropping

MPEG audio layer 3（MP3） compression

time-scale modification

frequency-scale modification.
