Kami mencadangkan kaedah untuk membenamkan data binari ke dalam aliran bit JPEG dan mengekstrak data terbenam daripada aliran bit JPEG menggunakan penyahkod JPEG standard. Dalam kaedah yang dicadangkan, kita boleh menyahkod imej daripada aliran bit JPEG yang mana data binari dibenamkan dahulu menggunakan penyahkod JPEG standard tradisional, dan kemudian kita boleh mengekstrak data binari terbenam dengan sempurna melalui pemprosesan pasca daripada imej JPEG yang dinyahkod. Untuk pemprosesan pasca, kami hanya menggunakan data imej yang dinyahkod untuk mengekstrak data binari terbenam. Iaitu, kita tidak memerlukan sebarang jenis parameter tertentu, yang digunakan untuk penyahkodan JPEG, seperti nilai jadual pengkuantitian. Oleh itu, kita boleh menggunakan penyahkod JPEG standard tradisional untuk pra-pemprosesan mengekstrak data binari. Tambahan pula, kami menangani kesan ketepatan bit pengiraan transformasi kosinus diskret (DCT) dan transformasi kosinus diskret songsang (IDCT) untuk mengekstrak data binari terbenam dengan sempurna sebagai pemprosesan pasca. Simulasi menggunakan mengekstrak data binari terbenam sebagai pemprosesan pasca dibentangkan untuk mengukur beberapa faktor prestasi yang berkenaan. Dan kami mengesahkan bahawa kaedah yang dicadangkan boleh digunakan secara praktikal.

Abstract: We proposed a method for embedding binary data into JPEG bitstreams and extracting embedded data from JPEG bitstreams using the standard JPEG decoder. In the proposed method, we can decode the image from JPEG bitstreams into which the binary data is embedded first using the traditional standard JPEG decoder, and then we can extract the embedded binary data perfectly by the post-processing from the decoded JPEG image. For the post-processing, we use only the decoded image data to extract the embedded binary data. Namely, we do not need any kind of particular parameters, which are used for JPEG decoding, such as quantization table value. Thus, we can use the traditional standard JPEG decoder for the pre-processing of extracting binary data. Furthermore, we address the effect of the calculation bit accuracy of discrete cosine transform (DCT) and inverse discrete cosine transform (IDCT) for extracting embedded binary data perfectly as post-processing. Simulations using extracting embedded binary data as post-processing are presented to quantify some performance factors concerned. And we confirmed that the proposed method could be of practical use.
