The aim of steganography is to hide information, such that the transmission of messages is transparent to any given viewer. Messages can be hided in different formats, such that they are undetectable and un-noticeable by human vision system. In this book, an image high hiding steganographic method for concealing digital image in a cover image is introduced, implemented and investigated. The technique used to embed the generated IFS-code, of the secret image, into the cover image is the Least-Significant-Bit (LSB) substitution method. The embedded secret image can be extracted from the resulting stego-image without need to referencing to the original secret image
