A Novel Data Hiding Method Using Sphere Encoding
In this paper a novel data hiding scheme using least square mapping is proposed. The method conceals a k-ary secret digit in n-pixel block in which the embedding function with minimum mean square error (MSE) between the cover block and the stego-block is searched. The constructions for the proposed method in three-pixel block (sphere encoding) under different k are demonstrated. Experiment results show that the proposed scheme achieves higher embedding efficiency than several reported steganographic schemes.
