Secure Modulus Data Hiding Scheme
In 2006, Zhang and Wang proposed a data hiding scheme based on Exploiting Modification Direction (EMD) to increase data hiding capacity. The major benefit of EMD is providing embedding capacity greater than 1 bit per pixel. Since then, many EMD-type data hiding schemes have been proposed. However, a serious disadvantage common to these approaches is that the embedded data is compromised when th...
متن کاملHiding Digital Information Using a Novel System Scheme
This work builds on Lin and Lee’s document protection scheme, termed as Confused Document Encrypting Scheme (CDES), to present a novel strategy that could hide digital information and provide secret communication between two communication parties. Lin and Lee invented a document protection scheme to transmit large quantities of secret information. However, their design strategy is only suitable...
متن کاملA Survey of Information Hiding Schemes for Digital Images
In this survey, we first describe the purposes for image hiding. They are Steganography, Image Watermarking and Image Authentication. Classified by hiding methods, image hiding can be divided into pixel-based image hiding, frequency-based image hiding and VQ-based image hiding. In the aspect of pixel-based image hiding, we describe three representative methods, the substitution table technique,...
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...
متن کاملNew Reversible Data Hiding Scheme for Encrypted Images using Lattices
Reversible data hiding is a technique to hide arbitrary data, without influencing the original images. In 2011, Zhang proposed a reversible data hiding scheme for encrypted images, by using a spatial correlation of the decrypted original image. Later, Hong et al. proposed an improved scheme by using side-match techniques, and modifying the correlation calculation function. In this paper, we pro...
