一种基于音频技术的信息隐藏方法

An Information Hiding Method based on Audio Technology

针对伪装信息对载体干扰方面的问题,文章提出了一种基于音频技术的信息隐藏方法,并形成了一种边信息对伪装信息进行频域与时域联合整形的方案。在限制载体对伪装信息干扰方面,文章扩展了改进扩频调制在收、发序列不匹配时的嵌入方法。实验结果表明,文章所提方案具有很好的信息隐藏效果。

Aiming at the problem of the interference of camouflage information to the carrier,this paper proposes an information hiding method based on audio technology,and forms a scheme of jointly shaping the camouflage information in the frequency domain and the time domain by the side information.In terms of limiting the interference of the carrier to the camouflaged information,this paper expands the embedding method of the improved spread spectrum modulation when the receiving and sending sequences do not match.The experimental results show that the proposed scheme has a good information hiding effect.
