Information Hiding Techniques for Image Covers
Singh, Harsh Vikram
The book presents three new methods of improving robustness of spatial and transform domain steganography without compromising with the minimum acceptable perceptual quality of the cover image containing hidden data. The suggested methods of spatial domain hiding perform data hiding into higher nibbles or moderatory bits (i.e. bits '2'' to '5'') of an 8-bit host image pixel using data matching or substitution with pixel gray value error minimi...
