为了改善 LSB 方法的稳健性和透明性,本文利用人类听觉系统的掩蔽效应来确定秘密信息的嵌入位置。实验表明,该算法隐藏数据量大、透明性好,且该算法可以用于在语音信号中隐藏文本、图像等信息数据。
In order to improve the robustness and transparency of the LSB method, this paper uses the masking effect of the human auditory system to determine the embedding position of secret information. Experiments show that the algorithm has a large amount of hidden data and good transparency. The algorithm can be used to hide text, image and other information data in speech signals.
