摘要：Hiding the information is a vital issue in the 21st century in the field of Data Communication security .Its an important issuebecause the virtual and digital information transmission faces critical setbacks due to hacking and hackers threats. Thetransmission of information via the Internet may expose it to detect and theft. The data embedding technologies are developedto provide personal privacy, commercial and national security interests. In this work we consider the problem of extractingblindly data embedded over a wide band in a spectrum (transform) domain of a digital medium (image, audio, video).Wedevelop a novel multicarrier/signature iterative generalized least-squares (M-IGLS) core procedure to seek unknown datahidden in hosts via multicarrier spread-spectrum embedding. Here the original host and the embedding carriers both areassumed as not available. Experimental results shows the proposed algorithm can achieve recovery probability of error close towhat may be attained with known embedding carriers and host autocorrelation matrix
