Data Hiding Scheme Based on Features of Chinese Text

Text data hiding is a steganographic technique different from the secrets hiding in multimedia, such as images, audio and video. Sun et al. proposed a text data hiding scheme to divide the Chinese character into left and right parts for enhancing the capacity, which is called L-R scheme. Adopting the concepts of Sun et al.´s scheme, Wang et al. proposed an improved version to incorporate the up and down components of Chinese characters rather than L-R scheme only. This paper combines another type of text properties, such as reiterative diction and erroneous character, into the proposed embedding scheme to increase the hiding capacity.
