一种基于采样点倒置的音频信息隐藏方法
Audio information hiding method based on samples dots Inversion
摘要
Abstract
This paper proposed a kind of new approach of hiding speech into the audio carrier. Utilized Logistic chaotic map as chaotic sequence to process the secure speech. Based on the features that audio sample dots inversion had little influence on the human hearing and that the percentage of the positive audio sample dots in a period of time was robust against some audio attacks, embedded the secret information to the audio by adjusting the percentage of the positive audio sample dots. Realized the adjustment by inversing audio sample dots. Experiment results show the speech which is embedded with secret information has good imperceptibility,and the algorithm is strongly robust to many attacks, such as关键词
