Design a data hiding scheme using RSA

In this paper, a robust data hiding scheme that combines shuffling method based on RSA and embedding the hidden message in spatial domain is proposed. Since 1984, the research of data hiding for images has received more and more attentions. Recently, a new method combines to find the best pixels of embedding data, odd-even mapping and shuffling to achieve the goal of data hiding is proposed by Wu and Liu. However, their scheme will face the destruction of attacker when the shuffling publishes. Our proposed method is not only improving the security of Wu-Liu scheme substantially but also achieving shuffling in public.
