Abstract
An LSB-based image steganography algorithm hides information in the least significant bits of the pixel intensities of a cover image. But such a method has a very low embedding capacity compared to a multi-bit embedding scheme. The latter is very challenging in the sense that the possibility of a large change in the pixel value of the cover image becomes very high and only a few algorithms based on multi-bit embedding exist in the literature. In this paper, we improve the multi-bit embedding technique of Park et al. (2005), and achieve higher capacity of embedding (at most 5 bits per pixel) and higher embedding efficiency (at most 5.33) into an image with lower distortion. We compare our performance with existing techniques and support our claim with theoretical and experimental results.
