A good visual quality of stego images is an important property of information hiding systems. This can be achieved by reducing the number of steganographic modifications during the secret data embedding phase. For concerning applications of mobile devices, a simple data embedding method with low power consuming can be used to embed secret data. In this paper, we propose a novel information hiding method to embed a secret message into a grayscale cover image. A segment of three secret bits is embedded into a group of seven cover pixels by replacing the LSBs of pixels in the group with a suitable covering code. The proposed method applies XOR operations to find a suitable bit pattern for data embedding and significantly reduces the cost of the chips requirement for mobile devices. The experimental results show that the proposed method achieves a good visual quality of stego images.
