In this era of internet development, security of information sharing is the main problem faced by human being. Data hiding technique is one of the solutions. However, hiding credential information within a multimedia file such as image reduces its visual quality. Therefore, unauthorized users may suspect the existance of secret data within that image. In the past years, various data hiding algorithms have been developed by researchers to overcome the problem of high distortion of image after data embedding process. Achieving a high quality stego image, however, is still a challenging problem. In this paper, we proposed a new data hiding algorithm based on different expansion. It aims to enhance the quality of stego image for a given payload size. The new algorithm is evaluated on various medical images. Thereafter, the experimental results show that the visual quality is improved; and increasing the embedding capacity leads to more noises. Therefore, a better choice of base point and a reduced difference expansion affect the quality of stego image.

“…Techniques that can handle the case called reversible data hiding, distortion-free, invertible, or lossless techniques. Reversible Data hiding facilitates application possibilities that can restore the media reservoir to their originals after the process of extraction [6], [7], [9]- [13]. The embedding and extraction process of reversible data hiding is shown in Figure 1 [5].…”

“…That is why the reversible data hiding techniques are often called the lossless data hiding techniques. Two main approaches for developing reversible data hiding techniques are the difference expansion (DE) [13][14][15][16] and the histogram shifting (HS) [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] approaches. Boato et al proposed a reversible data hiding scheme that combined the above two approaches in 2012 [15].…”

This paper proposes a reversible data hiding technique based on the residual histogram shifting technique. To improve the hiding capacity, this study proposes a multiple-round hierarchical prediction mechanism that generates the prediction errors of each image block. The prediction errors of each block are collected to produce the residual histogram and the secret data are then embedded into the residual histogram to obtain the embedded image. Experimental results demonstrate that the proposed technique not only provides good hiding capacity, but also maintains good image quality of the embedded image. In addition, this technique can be easily extended for image integrity protection as it is capable of resisting error propagation.
