摘要
音频伪装技术是信息隐藏技术领域的一个重要分支,在数字水印和隐蔽通信等方面有着广泛应用。作为一种寄生通信技术,音频伪装的应用需满足两个条件:一是要有能够携带隐藏信息的音频载体;二是音频载体要有冗余,能够容纳额外的隐藏信息而不显著降低自身的通信性能。文章在描述空气信道模型、干扰因素,人耳听觉系统的基础上,提出了一种面向空气信道的音频伪装模型。实验表明,文章提出的模型具有很好的鲁棒性。
Audio camouflage technology is an important branch of information hiding technology, which is widely used in digital watermarking and covert communication. As a parasitic communication technology, the application of audio camouflage needs to meet two conditions: one is to have an audio carrier that can carry hidden information;Second, the audio carrier should be redundant, able to accommodate additional hidden information without significantly reducing its own communication performance. Based on describing the air channel model, interference factors and human auditory system,this paper proposes an air channel-oriented audio camouflage model. Experiments show that the proposed model has good robustness.
