| 摘 要： | 为了更好地解决在窄带语音通信中进行强鲁棒性、高透明性信息隐藏这一难题，通过对人耳听觉和窄带通信系统模型的深入研究，提出了一种基于人耳听觉模型的窄带音频信息隐藏算法. 大量实验表明，该算法能很好地抵抗窄带通信中的D/A、A/D和信道噪声等攻击，具有很强的鲁棒性；在时域、频域，尤其是在听觉上具有很好的透明性. 同时，算法的隐藏容量可达20 bit/s，具备智能盲检测特性，有很高的实用价值. |

| Abstract: | After studying about human auditory system and narrowband communications system model, a narrowband audio hiding algorithm based on human auditory system was presented. A lot of experiments proved that the algorithm had strong robustness to prevent many attacks from such as D/A, A/D, channel noise and so on. In time domain, frequency domain, especially for hearing, it had high transparence. What’s more, the algorithm, whose hiding capacity reached up to 20 bit/s, had intelligent blind detection property and can be used in many domains. |
| Keywords: | human auditory system narrowband communications audio hiding intelligence training |
