Abstract: This paper considers irreversible coding by JPEG, and proposes a method of embedding binary data into the image. The proposed method embeds the information into the AC coefficients after quantization. The information is embedded in the AC coefficients of higher frequency, and by setting the quantization table corresponding to these AC coefficients to small values, visual image degradation is limited. In the proposed method, the embedded information is completely recovered in decoding, leaving little effect on the image after recovering the information. The coded sequence can be decoded using a conventional JPEG decoder, even in an environment where the information is not to be recovered or cannot be recovered. The method is designed so that image degradation is also limited in such a case. © 2001 Scripta Technica, Syst Comp Jpn, 33(1): 18–26, 2002 [ABSTRACT FROM AUTHOR]
