摘要：

摘 要：在对不同有效域的算法进行总结和分析的基础上，提出了一种基于振幅值修改的wav音频隐写算法。算法将秘密音频通过随机数生成器置乱，通过比较原始音频每个采样点分组中振幅值之间的关系，结合待嵌入的秘密信息位进行嵌入修改，嵌入强度依据密钥进行调节。实验结果表明，该算法具有较大的嵌入容量，不可感知性良好，具有一定的抗隐写分析能力，并可实现盲提取。

关键词: 振幅值修改, 音频隐写, 嵌入容量, 不可感知性

Abstract:

Algorithms in different effective domains are analysed,and a wav-audio steganography algorithm based on amplitude modifying is proposed.The secret audio is scrambled through a random number generator.Amplitude values of each sampling point group are compared in original audio.While amplitude values are modified,the secret information bits are embedded.Embedding strength can be adjusted according to the key.Simulation results demonstrate that hiding capacity of this algorithm is large and good invisibility can be achieved.The anti-steganalysis ability of this algorithm is good and blind extraction can be realized.
