A REVIEW ON BLIND STILL IMAGE STEGANALYSIS TECHNIQUES USING FEATURES EXTRACTION AND PATTERN CLASSIFICATION METHOD

摘要: Steganography is the technique for hiding secret information in other data such as still, multimedia images, text, audio. Whereas Steganalysis reverse which detection of done stego image. can be classified on basis techniques used statistical techniques, pattern classification and visual .All existing broadly required designing steganalysis. They are targeted blind steganalysis In technique, we first look at designed a particular steganographic embedding algorithm mind whereas general class implemented with any algorithm, even an unknown algorithm. this paper, extensive review report presented chronologically Blind Image still images using techniques.
