Reversible data hiding based on prediction error expansion using adjacent pixels
For some applications such as satellite and medical images, reversible data hiding is the best solution to provide copyright protection or authentication. Being reversible, the decoder can extract the hidden data and recover original image without distortion. In this paper, a reversible data hiding scheme based on prediction-error expansion is proposed. The predictive value is computed by using...
متن کاملImproved reversible data hiding through full employment of image pixels
A new reversible data hiding algorithm for digital images is proposed in this paper. A single key parameter is derived in the algorithm during the hiding process. This parameter must be transferred to extract data. A 3 × 3 window slides over the cover image by one pixel unit, and one bit can be embedded at each position of the window. Thus, the ideal maximum hiding capacity is equal to the numb...

متن کاملEnsemble Reversible Data Hiding
The conventional reversible data hiding (RDH) algorithms often consider the host as a whole to embed a payload. In order to achieve satisfactory rate-distortion performance, the secret bits are embedded into the noise-like component of the host such as prediction errors. From the rate-distortion view, it may be not optimal since the data embedding units use the identical parameters. This motiva...
متن کاملReversible Data Hiding
Reversible data hiding, in which the stago-media can be reversed to the original cover media exactly, has attracted increasing interests from the data hiding community. In this study, the existing reversible data hiding algorithms, including some newest schemes, have been classified into three categories: 1) Those developed for fragile authentication; 2) Those developed for achieving high data ...
