CREATING STEGO-IMAGES THROUGH HIDING SINGLE AND MULTIPILE DATA USING DIFFERENT STEGANOGRAPHIC TOOLS

摘要

Recently, the concept of ‘Image Steganography’ isrnbecame an important issue in the computer security world.rnImage steganography simply means hide some secret datarninto an object. The object can be a text, an image or arnsound, but the most popular cover object used for hiddenrnsecret message is images.rnOn the other hand, to detect these hidden messages, manyrnmethods and techniques can be used as well. However,rnthe procedures of detecting any hidden data, is calledrn‘Steganalysis’.rnThis paper focuses on creating stego-images throughrnhiding secret messages into clean images. It also reviewsrnsome image steganography methods and tools. In order torncreate a number of stego-images, three steganographicrntools are used. They are: OpenStego, S-Tools and F5rnalgorithm. With respect to the hidden data, one and morernhidden data file is embedded. In addition, testing forrndifferentiating between stego-images created and thernclean one is presented.
