An Efficient Data Hiding Scheme using Hamming Error Correcting Code

In this paper, we propose an efficient secure partially reversible data hiding scheme using hamming error correcting code (PRDHHC). Recently, Kim et al. proposed a data hiding technique in halftone image which hides four secret bits within (4 x 4) image block through codeword. Lien et al. presented data hiding scheme using hamming code by generating dispersed block through space filling curve decomposition using fifteen bits codeword. Here, we propose data hiding scheme through error creation in three least significant bits of a (7 x 7) image block using shared secret key. During extraction, the receiver finds the error position within three least significant bits of the image block and extracts secret data with the help of shared secret key. After extraction, we complement the error bits to achieve partial reversible data hiding. Our scheme is compared with other state-of-the-art methods and we obtain reasonably good performance in terms of PSNR and embedding capacity.
