EA based Heuristic Segmentation for Efficient Data Hiding

EA based Heuristic Segmentation for Efficient Data Hiding

Information concealment is of paramount importance in information and communication security. For the protection of information and intellectual property, effective techniques are needed. Steganography is the art of writing concealed information in a way that it does not arouse suspicion about its existence. This ensures that only the sender and the recipient are aware of the concealed message ...

Efficient BEMD Data Hiding Algorithm

Improved BEMD steganographic algorithm to hide secret text behind cover pixels of image to increase security of digital communication for exchanging private information worldwide using binary coefficient and modulus is proposed. From simulation results, Stego image quality better than 70dB which is higher than BEMD Kuo-Chang scheme thereby reducing mean square error difference between cover ima...

Efficient Reversible Data Hiding Algorithms Based on Dual Prediction

In this paper, a new reversible data hiding (RDH) algorithm that is based on the concept of shifting of prediction error histograms is proposed. The algorithm extends the efficient modification of prediction errors (MPE) algorithm by incorporating two predictors and using one prediction error value for data embedding. The motivation behind using two predictors is driven by the fact that predict...

An Algorithm for Data Hiding Using Median Cut Segmentation

Efficient data hiding with histogram-preserving property

For improving the steganographic security, the data-hiders always hope to lower the distortion level and to preserve the original data distribution. A novel efficient data hiding scheme with a histogram-preserving property is proposed in this work. After decomposing cover samples into a series of binary sequences, a number of candidate vectors representing each secret bit-block are produced, an...
