Abstract
The embedding capacity and stego-image quality are two important features in data-hiding schemes. In 2016, Kuo et al. introduced sparse modified signed-digit (SMSD)-based data hiding that could embed secret data into a group of n cover-pixels. Compared with previous exploiting modification direction (EMD) and generalized EMD (GEMD)-based data hiding, SMSD data hiding has higher embedding capacity and better stego-image quality. In this paper, we introduce a new definition of the enhanced MSD (EMSD) representation and propose an EMSD-based data-hiding scheme that improves the embedding capacity of SMSD data hiding and maintains equal quality of the stego-image. In addition, the embedding capacity in the proposed scheme is further improved using the section-wise approach in EMSD data hiding.
