Abstract

To solve the problem that the speech information hiding algorithm based on random position selection and matrix coding has insufficient hiding capacity, the paper proposes a novel pitch modulation steganography method based on inactive frame. In this method, the least significant bit (LSB) replacement method is adopted for inactive frames, and the speech information hiding algorithm based on random position selection and matrix coding is adopted for active frames, which realises the pitch modulation information hiding method based on inactive frames. Finally, simulation experiments are carried out for the pitch modulation information hiding method based on inactive frames. The results indicate that the maximum hiding capacity of the algorithm in this paper can reach 241.67 bps, which significantly improves the hiding capacity, and at the same time the concealment has also been improved to a certain extent.

一种基于基音调制的非活动帧语音信息隐藏方法

针对基于随机位置选择和矩阵编码的语音信息隐藏算法隐藏能力不足的问题，提出了一种基于非活动帧的基音调制隐写方法。该方法对非活动帧采用最低有效位(LSB)替换方法，对活动帧采用基于随机位置选择和矩阵编码的语音信息隐藏算法，实现了基于非活动帧的基音调制信息隐藏方法。最后，对基于非活动帧的基音调制信息隐藏方法进行了仿真实验。结果表明，本文算法的最大隐藏容量可达241.67 bps，显著提高了隐藏容量，同时隐蔽性也有一定程度的提高。
