摘要： A method for hiding message information into media information in frequency space. The data hiding method has high resistance to removal or change of message information embedded into media information and effectively maintain hidden message information even when signal processing is performed by employing a frequency filter. More specifically, in order to hide message information (m) into media information (M), the frequency transform of the message information (m) and the media information (M) are performed, and frequency spectra f1 and f2 are obtained. Next, from the frequency spectrum f2 of the message information (m), a region containing feature frequency components representative of the features of the message information (m) in real space is extracted as the base region B. Then, n copies of the base region B are generated, and in frequency space, the n copies are dispersedly arranged.
