Reversible Data Hiding Using Contrast Enhancement Approach
Reverse Data Hiding is a technique used to hide the object's data details. This technique is used to ensure the security and to protect the integrity of the object from any modification by preventing intended and unintended changes. Digital watermarking is a key ingredient to multimedia protection. However, most existing techniques distort the original content as a side effect of image protecti...
متن کاملReversible Image Data Hiding with Local Adaptive Contrast Enhancement
Recently, a novel reversible data hiding scheme is proposed for contrast enhancement by Wu (IEEE Signal Process Lett 22.1:81–85, 2015). Instead of pursuing the traditional high PSNR value, he designs the message embedding algorithm to enhance the contrast of the host image. In this paper, an extended scheme is proposed to not only adaptively enhance the contrast of the image, but also to keep t...

متن کاملReversible Data Hiding for Embedding Capacity Enhancement
Having dealt with the first two important criteria for data embedding in medical images namely, robustness towards attacks and imperceptibility to human visual system, the third and final most important criterion is optimizing the data hiding capacity parameter. This is especially a very important criterion since it deals with medical data management. Embedding of data over digital images can c...
متن کاملImproving histogram-based reversible data hiding by interleaving predictions
Data hiding is an important way of realising copyright protection for multimedia. In this study, a new predictive method is proposed to enhance the histogram-based reversible data hiding approach on grey images. In those developed histogram-based reversible data hiding approaches, their drawbacks are the number of predictive values less to the number of pixels in an image. In these interleaving...
