Most of the existing schemes either have the low image quality, or provide the restricted embedding capacity. In this talk, a new data hiding scheme based on turtle shell is introduced to obtain better image quality and higher embedding capacity. In the proposed scheme, a secret digit is embedded into each cover pixel pair with the guidance of the turtle shell. Experimental results reveal that the proposed scheme ensures not only higher embedding capacity, but also obtains better visual quality compared with the existing schemes. |
