基于可量化性能分级的自适应IP语音隐写方法
Adaptive Voice-over-I P Steganography Based on Quantitative Performance Ranking
摘要
Abstract
In this paper,we first analyze the unequal impacts of various cover bits on the quality of decoded speech for parameter codecs,and further design a ranking scheme for available cover bits to utilize the cover fully.Moreover,we present an adaptive VoIP steganography based upon the performance ranking of cover bits,which can adaptively choose the optimal steganographic positions to enhance the imperceptibility of covert communications.The proposed methods are evalu-ated and tested with a large number of speech samples as the cover.The experimental results show that the proposed ranking scheme is sound and feasible,and the presented steganogaphic method also outperforms the existing ones.关键词
