New Generating Technique for Image Steganography
Seifedine Kadry, Sara Nasr · Lecture Notes on Software Engineering · 2013
Steganography is used to send secure data hidden in image or another type of media in order to prevent intruders from detecting it.Image steganography depends on existing images so that data bits may be added to the image bits or replace some bits of it, the goal is to hide the bits of a secret text behind image bits so that no one other the sender and the receiver can discover what this file include beneath the cover image.Our developed 'New Generating Technique' (NGT) is based on generating the image from the text that we want to send securely.This means no additional data is added to the initial text it is just a change in its format so that we can send it safely.This may be done using different image formats starting with grayscale images to 24 bits.The most important advantage in our proposed steganographic technique is that it does not require an additional image to hide the text beneath it, besides it has a small size and very fast in comparison with other techniques.
