Abstract
Steganography is one of the most important approaches for secure transmission by concealing secret data into a host image imperceptibly. To achieve a good tradeoff between the hiding capacity and image quality, more work needs to be further researched. In this paper, to obtain satisfactory results, a Bi-Stretch Hiding (BSH) algorithm for absolute moment block truncation coding (AMBTC)-compressed image is proposed. In the scheme, the AMBTC-compressed image is divided into non-overlapped blocks first, after that, four feasible cases are employed to embed secret data, which takes advantage of the characteristics of the coefficients of the AMBTC-compressed image and lead tiny distortion of the AMBTC-compressed image. The experimental results demonstrate that the proposed BSH scheme outperforms the other state-of-the-art compression data hiding methods.
