An Adaptive EMD Embedding Method by Condensing Secret Messages Based on Consecutive Ones Transformation and Token Substitution

摘要

A new exploiting modification direction embedding method (also called the EMD embedding for short) was proposed by Zhang et al. to show that their proposed method has high embedding capacity and high stego-image quality as well because at most one cover pixel need increase/decrease by one among n cover pixels. Adopting the advantages of the EMD embedding method, we develop a condensed technique based on consecutive ones transformation and token representation to squeeze out of more embedding spaces for secret data to be embedded in a cover image. This contributes data embedding capacity.
