چکیده:

In this paper, we propose a reversible data hiding method with low time complexity and high embedding capacity for gray-scale images. This method presents a block-based lossless data hiding schema to utilize the similarity between neighbourhood pixels in the block to improve the marked-image quality. The experimental results show that our method has increased the hiding capacity with keeping acceptable markedimage quality.
