In 2008 Lin et al. proposed a reversible steganographic method with a high payload for JPEG images. Because modifying the quantized DCT coefficients may lead to serious image distortion, Lin et al. embedded the secrets into the middle frequency of the quantized DCT coefficients. Moreover, they limited the number of nonzero values of the quantized DCT(More)
In this paper, we combine absolute moment block truncation coding (AMBTC) and Shamir's secret sharing scheme to propose a verifiable secret sharing scheme. Shares construction is based on the compression codes generated by AMBTC; therefore, the shadow size is about one third of the original secret image. During the shares construction phase, the compression(More)
