Abstract
Reversible data hiding is the technique that allows embedding (hide) data inside an image and later the hidden data can be retrieved as required and the exact copy of the original image is found. One of the most important requirements of reversible data hiding is that the distortions to the original signal should be such that artifacts are not visible. Because these distortions create problems in some fields such as medical, astronomical, and military images due to legal reasons. Another requirement is to have higher embedding capacity. The reversible data hiding is an emerging field for content authentication of images where the authentication information (say hash) is embedded inside the image. The higher the capacity the more information can be embedded inside the image. In this paper we present a review of reversible watermarking techniques proposed so far and give suggestions how to get reversible data hiding technique with higher embedding capacity and invisible artifacts.
