Steganalysis of Compressed Speech Based on Markov and Entropytional entropy features of the track pulses are extracted; a support vector machine (SVM) is then applied to the features for discovering the existence of hidden data in compressed speech signals, respectively. Some famous CDBS methods on ACELP encoded speech are considered. Experimental results have proven the effectiveness of the two methods.

Maurizio Ugliano,Paul A. Henschkes the recovering process is simple and fast. In addition, EDBTC-compressed images instead of the original format images are selected as shadows, which can improve the efficiency for data transmission and storing. The experimental results demonstrate that the proposed scheme offers a high secure and effective mechanism for secret image sharing.

描述

Richard Marchal,Philippe Jeandetts. With an encrypted video containing hidden data, data extraction can be carried out either in encrypted or decrypted domain. In addition, real reversibility is realized, that is, data extraction and video recovery are free of any error. Experimental results demonstrate the feasibility and efficiency of the proposed scheme.
