A Data Hiding Method Using Secret Data Division and Pixel Value Differencing

In this paper, we propose a new data hiding method. We divide cover-image into many non-overlapping blocks. Each block consists of two contiguous pixels. We separate the secret data into two parts. These two parts of secret data are hidden into two pixels of the block. The hiding capacity is depended on the difference value of the two points. If the difference value is higher, we embed more bits of secret data into the pixels. We also apply the modulus operation to embed the separated data. All cases of pixel pairs are used to show the performance and compare with the previous scheme. The experimental results show that the proposed technique has higher quality.
