This book proposes and evaluates secure and robust image steganography techniques in DCT and Wavelet transform domain. The wavelet transforms being investigated in this work are Integer Wavelet Transform (IWT) and Redundant Discrete Wavelet Transform (RDWT). We attempt to enhance the security and robustness by combining embedding domain transform with chaotic sequence, Singular Value Decomposition, and Arnold Transform. The proposed methods are evaluated against different image processing and geometrical operations like JPEG compression, noise addition, filtering, cropping and re-sizing...
