Paper Abstract

In this paper, a new data hiding method - writing on wet paper using multi-pixel differencing is presented in order to provide large embedding capacity and improve further steganographic embedding efficiency for the stego-image. It takes into consideration four pixels of a block, and the differences between the lowest gray-value pixel and its surrounding pixels are used to embed the secret data. The receivers can extract secret bits from carrier images only by some matrix multiplications no matter how we embed the secret message. Thus, the invisibility of this steganographic method is achieved in process of secret information transmission. The experimental results show that our scheme has a larger embedding capacity and better robust performance against the methods of active attacks such as noise addition.
