Use of Three-Form Module Substitution to Hide Data

Abstract

A simple, adaptive data hiding method by employing the three-form module substitution is proposed. In accordance with the local variance of the blocks, a variety of secret bits are effectively embedded in each block via one of the three-form module substitution. Experiments show that both the PSNR and hiding rate generated by the proposed method are better than those generated by the reported methods. Since the perceived quality of the resulting mixed images is good, the proposed method has an extra merit of being attracted hardly by the third parties.
