Abstract: This paper proposes a reversible data hiding scheme for BTC-compressed images. A block in the BTC-compressed image consists of a larger block-mean pixel and a smaller block-mean pixel. Two message bits are embedded into a pair of neighboring blocks. One is embedded by expanding the difference between the two larger block-mean pixels and the other is embedded by expanding the one between the two smaller block-mean pixels. Experimental results show that the embedding strategy may decrease the modification of images. The proposed scheme may obtain a stego-image with high visual quality and a payload capacity of one bit per block, approximately.
