  • 摘要:We consider the problem of extracting blindly data embedded over a wide band in a spectrum(transform) domain of a digital medium (image, audio, video). We develop a novel multi-carrier/signature iterativegeneralized least-squares (M-IGLS) core procedure to seek unknown data hidden in hosts via multi-carrier spreadspectrumembedding. Neither the original host nor the embedding carriers are assumed available. Experimental studieson images show that the developed algorithm can achieve recovery probability of error close to what may be attainedwith known embedding carriers and host autocorrelation matrix.
