Abstract

Abstract: Based on the analysis of Fractional Fourier Transform（FRFT），it presents an audio information hiding algorithm based on Singular Value Decomposition（SVD） and FRFT in the use of FRFT’s time-frequency characteristics，singular eigenvalue’s stability and power function’s scaling properties.The experimental results show that the algorithm has good imperceptibility，and robust against the attacks of noise adding，re-sampling，requantization，MP3 compression and frequency domain malicious attack.

Key words: discrete fractional Fourier transform, singular value decomposition, information hiding

摘要： 在分析分数阶傅里叶变换（FRFT）的基础上，利用FRFT的时频特性、奇异特征值的稳定性及幂函数的缩放特性，提出了一种基于SVD和FRFT的音频信息隐藏算法。实验结果表明，该算法具有很好的不可感知性，且对加噪、重采样、重量化、MP3压缩及频域恶意攻击具有很强的鲁棒性。
