Due to the rapid developments in multimedia, the demand for binary media (such as signatures, scanned documents and images) based steganographic system has enhanced. In this paper, we present a new data-hiding system that could hide considerable amount of data into a binary digital media. The system modifies the maximum flippable pixels in each block based on certain statistics constraints and characteristic measure of the block. Thus equalizing, the uneven distribution of the flippable pixels through out the embeddable image blocks. We also discuss various issues surrounding the variable block embedding rate and the solution to those issues to make it feasible. The embedded information can be reconstructed without prior knowledge of the cover. The performance of the proposed embedding system with respect to the security and robustness is also discussed. Comparisons with the commonly used embedding systems are also presented for maximum capacity and visual distortion.
