Reversible data hiding [PDF]

IEEE Transactions on Circuits and Systems for Video Technology, 2003
A novel reversible data hiding algorithm, which can recover the original image without any distortion from the marked image after the hidden data have been extracted, is presented in this paper. This algorithm utilizes the zero or the minimum points of the histogram of an image and slightly modifies the pixel grayscale values to embed data into the ...

Hierarchy-based reversible data hiding [PDF]

Expert Systems with Applications, 2013
In this paper, we propose a new method for reversible data hiding by employing the hierarchical relationships of original images. There are many parameters for accessing the performances of reversible data hiding algorithms, including the output image quality, the hiding capacity, and the overhead for decoding.

Reversible Data Hiding in Encrypted Image

IEEE Signal Processing Letters, 2011
This work proposes a novel reversible data hiding scheme for encrypted image. After encrypting the entire data of an uncompressed image by a stream cipher, the additional data can be embedded into the image by modifying a small proportion of encrypted data.

Separable Reversible Data Hiding in Encrypted Image

IEEE Transactions on Information Forensics and Security, 2012
This work proposes a novel scheme for separable reversible data hiding in encrypted images. In the first phase, a content owner encrypts the original uncompressed image using an encryption key. Then, a data-hider may compress the least significant bits of the encrypted image using a data-hiding key to create a sparse space to accommodate some ...
