Efficient Pixel Prediction Algorithm for Reversible Data Hiding
Prediction-error expansion (PEE) is an important reversible data hiding technique, which can hide large messages into digital media with little distortion. In this paper, we propose a nearest neighborhood pixel prediction algorithm (NNP) for reversible data hiding algorithms based on Chinese Remainder Theorem (CRT), in which a rhombus prediction is applied in NNP, and prediction errors, the dif...
متن کاملReversible Data Hiding Based on Geometric Structure of Pixel Groups
Many reversible data hiding schemes have been developed in recent decades. Traditional schemes typically must deal with the problem of overflow and underflow, or transmission of hiding parameters. The new reversible data hiding scheme proposed in this paper is based on a combination of pixel groups’ geometric structure and secret sharing mechanism. Experimental results confirm that the proposed...
متن کاملData Hiding Method Based on Graph Coloring and Pixel Block‘s Correlation in Color Image
An optimized method for data hiding into a digital color image in spatial domainis provided. The graph coloring theory with different color numbers is applied. To enhance thesecurity of this method, block correlations method in an image is used. Experimental results showthat with the same PSNR, the capacity is improved by %8, and also security has increased in themethod compared with other meth...
متن کاملPerformance Analysis of Data Hiding Using Adjacent Pixel Difference Technique
Steganography aims at hiding a text/message in an image in such a way that only receiver knows its existence. A natural image has many smooth areas. In recent years, various techniques are used for hiding data in the smooth areas of the image using digital image processing with varying degree of goodness. The prime goal is to enhance the data hiding capacity without much deteriorating the quali...
متن کاملDual-Image Based Reversible Data Hiding Scheme Using Pixel Value Difference Expansion
In this paper, we propose a dual-image based reversible data hiding scheme. Here, we divide a secret message into sub-stream of size n bits, where n − 1 bits are embedded using Pixel Value Differencing (PVD) and 1 bit is embedded using Difference Expansion (DE). We consider two consecutive pixels from cover image, calculate the difference between them and then embed n − 1 bits secret message by...
