An Efficient Prediction-and-Shifting Embedding Technique for High Quality Reversible Data Hiding
The embedding capacity of a histogram-based reversible data hiding technique is primarily determined by the peak height of the histogram. Recently, some studies have tried to embed data in the histogram of prediction errors by modifying the error values and have better embedding efficiency. However, these methods offer no selective embedment mechanism to exclude the positions where the modifica...
متن کاملA reversible high embedding capacity data hiding technique for hiding secret data in images
As the multimedia and internet technologies are growing fast, the transmission of digital media plays an important role in communication. The various digital media like audio, video and images are being transferred through internet. There are a lot of threats for the digital data that are transferred through internet. Also, a number of security techniques have been employed to protect the data ...
متن کاملGeneralized PVO-K Embedding Technique for Reversible Data Hiding
Recently, several reversible information hiding methods based PVO (pixel value ordering) techniques have been proposed, in these methods, secret data always are embedded in pixels with largest or smallest value in the block. In order to make use of the block with multiple largest-valued (or smallest-valued) pixels, a PVO-K method was proposed, which treats K largest-valued (or smallest-valued) ...
متن کاملA Novel Reversible Data Hiding Technique based on Histogram Shifting and Efficient use of Location Map
In this paper a reversible data hiding method which uses a novel algorithm based on histogram sifting is proposed. The distortion that occurs due to embedding can be completely removed during the data extraction. The proposed method uses double embedding to increase the reversibility. Location map information is embedded into the image itself, so that the reversibility can be easily achieved. T...
