Steganalysis of Compressed Speech
Bao Chun-lan, Huang Yong-feng, Zhu Chun-yi · 2006
Based on the analyzing of the redundancy of coded parameters in G.723.1, a novel approach to detect hiding information is proposed in this paper. By using the statistical value of increaser entropy, this scheme can not only detect hidden messages embedded in compressed speech, but also estimate the embedded message length accurately .The experimental results show that the proposed scheme is effective.
