Abstract :
This paper discusses the LTSB (least two significant bits) steganalysis technique, and presents a detection method based on quartic equation (QEM). This method constructs a finite-state machine based on image pixel sample pairs, and then builds a quartic equation via those states conversion relation. Finally, solves the equation and obtains the embedding ratio estimated value. Experimental results show that this approach can estimate the length of embedded message and make a reliable decision whether the image is a steg-image or not
