论文摘要
隐肌是一种可以改善网络安全性并使通信更安全的方法。在此方法中,秘密消息隐藏在诸如音频信号之类的内容中,通过聆听音频或看到信号波,不应觉得该信号。同样,它应该对不同的常见攻击(例如噪声和压缩)具有鲁棒性。在本文中,我们提出了一种基于离散小波变换,基于图的变换和奇异价值分解(SVD)的组合的新语音隐身方法。在这种方法中,我们首先根据框架的能量和零交叉计数找到声音帧,然后将二进制消息嵌入到声音帧中。 Noizeus数据库的实验结果表明,该方法是不可察觉的,并且在高斯噪声,重新采样,重新定位,高通滤波器和低通滤波器上也有鲁棒性。此外,对于水印应用,它对MP3压缩和缩放也是可靠的。
Steganography is a method that can improve network security and make communications safer. In this method, a secret message is hidden in content like audio signals that should not be perceptible by listening to the audio or seeing the signal waves. Also, it should be robust against different common attacks such as noise and compression. In this paper, we propose a new speech steganography method based on a combination of Discrete Wavelet Transform, Graph-based Transform, and Singular Value Decomposition (SVD). In this method, we first find voiced frames based on energy and zero-crossing counts of the frames and then embed a binary message into voiced frames. Experimental results on the NOIZEUS database show that the proposed method is imperceptible and also robust against Gaussian noise, re-sampling, re-quantization, high pass filter, and low pass filter. Also, it is robust against MP3 compression and scaling for watermarking applications.
