Reversible data hiding using the companding technique and improved
- DE method,” Circuits, Systems, and Signal Processing
, 2008
"... Abstract A novel reversible data hiding scheme based on the companding technique and an improved difference expansion (DE) method is presented in this article. The companding technique is employed to embed payload into high frequency bands in the integer wavelet transform (IWT) domain. A refined met ..."

Novel Spatial Domain Reversible Information Hiding Technique for Content Authentication
"... Abstract. In this paper we propose a transparent, computationally simple and fast spatial domain data hiding technique for content (image and audio) authentication purposes. It can also be used in data captioning, copyright protection, confidentiality and integrity over the property distributed in ..."

Research Article An Efficient Prediction-and-Shifting Embedding Technique for High Quality Reversible Data Hiding
"... permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. 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 d ..."

A FRAGILE WATERMARKING BASED ON BINOMIAL TRANSFORM IN COLOR IMAGES
"... In this paper, a novel Binomial Transform based fragile image watermarking technique has been proposed for color image authentication. The Binomial Transform (BT) is used to convert each 2 × 2 sub-image block of the carrier image into transformed block corresponding to red, green and blue channels i ..."

Steganography using Coefficient Replacement and Adaptive Scaling based on DTCWT
"... Steganography is an authenticated technique for maintaining secrecy of embedded data. Steganography provides hardness of detecting the hidden data and has a potential capacity to hide the existence of confidential data. In this paper, we propose a novel steganography using coefficient replacement an ..."

MPEG-4 for Interactive Low-delay Real-time Communication
, 2003
"... ii Internet broadcasting techniques are wide spread and have been the focus off many research projects. Due to high transmission delays these systems often lack interactivity. This thesis introduces a new streaming system to deliver real-time video and audio data with low-delays across the Internet. ..."
