In this paper, we present a new reversible data hiding method based on joint neighboring coding. The proposed method uses the side-match distortion (SMD) function to sort the codebook so as to make an index value become very close to its neighboring index values, then the residual value between the index and its neighboring index is obtained by bitwise exclusive-OR operation and the secret bits are...
Information hiding method with low bit rate is important in secure communications. To reduce bit rate we propose a new embedding method in this paper based on SOC (search-order coding) compression technique. Compared to Chang et al.’s scheme in 2004, our scheme completely avoids the transform from SOC coding to OIV (original index values) coding to significantly reduce bit rate. In order to further...
