“…It worth to note that the PSNRs of our scheme for most test images are still higher than 30dB. The bit rates of the proposed scheme are nearly 30% less than those of scheme [8]. Furthermore, the proposed scheme is able to embed 16,348 bits along with compression in each test image, while scheme [8] is just a pure compression scheme.…”

“…The results conducted by the suggested (R, TH) in the proposed scheme are used to compare with Xiang et al's scheme [8], Qin et al's scheme [15], and Qin et al's JDHC scheme [19] in this subsection. Scheme [8] is a pure BTC based compression scheme with outstanding compression rate and visual quality, but their scheme could not hide secret data.

“…In addition, the stego-image would also keep very high visual quality, where the PSNRs of the stego-images are guaranteed to be more than 30 dB. To show the comparison results, the proposed scheme is further compared with the representative BTC compression scheme [8], BTC based data hiding scheme [15], and JDHC scheme [19].…”

Seamlessly integrating image compression technique and secret data hiding technique into a single procedure for security and efficient data transmission is a novel research issue in modern, decentralized digital communication environments. The first joint data hiding and compression (JDHC) scheme on block truncation coding (BTC) compression domain is presented in this paper. In the compressing and embedding procedure, for the complex blocks, modified block truncation coding (MBTC) is utilized to embed secret data and compress blocks simultaneously, while further controlling the visual distortion that is caused during data embedding. For the smooth blocks, according to the current embedding bit, either image inpainting or block search order coding (BSOC) is used to embed secret data and compress blocks simultaneously with maintaining acceptable compression performance. According to the image compression codes that are provided as output, image decompression and secret bits extraction procedures can be conducted simultaneously. Experimental results indicate that outstanding compression bit rate can be achieved by the proposed JDHC scheme with satisfactory visual quality and hiding capacity.
