This book covers newly developed and novel Steganography techniques and algorithms. The book
outlines techniques to provide security to a variety of applications using Steganography with
the goal of both hindering an adversary from decoding a hidden message and also preventing an
adversary from suspecting the existence of covert communications. The book looks into applying
these newly designed and improved algorithms to provide a new and efficient Steganographic
system called Characteristic Region-Based Image Steganography (CR-BIS). The algorithms combine
both the robustness of the Speeded-Up Robust Features technique (SURF) and Discrete Wavelet
Transform (DWT) to achieve characteristic region Steganography synchronization. The book also
touches on how to avoid hiding data in the whole image by dynamically selecting characteristic
regions for the process of embedding. Applies and discusses innovative techniques for hiding
text in a digital image file or even using it as a key to the encryption Provides a variety of
methods to achieve characteristic region Steganography synchronization Shows how Steganography
improves upon cryptography by using obscurity features.
