Random Image Steganography ��� Spatial and Transform Domain Approach

This book contains seven chapters which are related with the design and development of Random Image steganography techniques in Spatial and Integer Wavelet Transform Domain. Experimental results are presented and compared with existing methods. Chapter 1 discusses the Classification of Information Security and Digital Image Steganography and the characteristics of Digital Image Steganography systems. Chapter 2 contains a detailed literature survey on existing Digital Image Steganography under Spatial and Transform Domain. Chapter 3 explains the implementation of Spatial Domain Random image steganography technique using Pixel Value Differencing (PVD) and Knight’s Tour. Chapter 4 deals with the Implementation of Transform Domain Random image Steganography using Haar Integer Wavelet Transform and 5/3 IWT in adaptive and non-adaptive cases. Chapter 5 concentrates on the IWT domain Random image Steganography with Knight’s Tour. Chapter 6 discusses the IWT domain Random image Steganography with Graceful Graphs. Chapter 7 concludes the entire work with a comparative analysis of the proposed Spatial and Transform domain steganography techniques.
