This paper presents two secret hiding schemes based on absolute moment block truncation coding (AMBTC). One is for embedding secrets into complex blocks and the other one is for smooth blocks. As for the smooth blocks, the small variation of the block is adopted to define the embedding rule to minimize the distortion after data embedding. As for the complex blocks, the large variation of the block is used to embed more secrets while maintaining good visual quality. In the experiments, when… CONTINUE READING
