-\section{Analysis of Steganographic Approaches}
-\input{analysis.tex}

 
 

-This work considers digital images as covers and fondation is
-spatial least significant-bit (LSB) replacement.
-I this data hiding scheme a subset of all the LSB of the cover image is modified 
-with a secret bit stream depending on to a key, the cover, and the message to embed.
-This well studied steganographic approach  never decreases (resp. increases)
-pixel with even value (resp. odd value) and may break structural symetry.
-This structure modification is detectable by statistical approaches 
-and thus by steganalysis methods~\cite{Dumitrescu:2005:LSB:1073170.1073176,DBLP:conf/ih/2005,FK12}. 
+\begin{abstract}

 
 

+A new steganographic method called STABYLO is introduced in 
+this research work.
+Its main advantage is to be much lighter than the so-called
+HUGO, WOW, and UNIWARD schemes, the state of the art
+steganographic processes.
+Additionally to this effectiveness, 
+quite comparable results through noise measures like PSNR-HVS-M 
+and weighted PSNR (wPSNR) are obtained.
+To achieve the proposed goal, famous experimented 
+components of signal processing, 
+coding theory, and cryptography are combined together, leading to 
+a scheme that can reasonably face up-to-date steganalysers.

+The STABYLO algorithm, whose acronym means STeganography with 
+Adaptive,  Bbs, and binarY embedding at LOw cost, has been introduced 
+in this document as an efficient method having comparable, though
+somewhat smaller, security than well-known
+steganographic schemes  
+HUGO, WOW, and UNIWARD.
+This edge-based steganographic approach embeds a Canny
+detection filter, the secure Blum-Blum-Shub cryptosystem 
+with its pseudorandom number generator, 
+together with Syndrome-Trellis Codes
+for minimizing distortion.
+The complexity study of our proposed method and of the  
+state of the art steganographic tools has shown that our approach 
+has the lowest computation cost among all. 
+This justifies the lightweight attribute of our scheme.
+The evaluation of introduced noise measures 
+(namely, the PSNR, PSNR-HVS-M, and weighted PSNR), 
+and of its embedding through stegenalysers (namely Ensemble Classifier)  
+have shown that STABYLO is efficient enough to 
+produce qualitative images and 
+to face steganalysers.

+% Of course, other detectors like the fuzzy edge methods
+% deserve much further attention, which is why we intend 
+% to investigate systematically all of these detectors in our next work.

 
 
 
 

+For future work, the authors' intention is to investigate systematically 
+all the existing edge detection methods, 
+to see if the STABYLO evaluation scores can
+be improved by replacing Canny with another edge filter.
+Moreover, we plan to improve the distortion function by integrating 
+into a numerical cost the gradient value of this kind of
+algorithm. We could thus transmit this value to STC contrary to the current 
+version where the distortion that is transmited is either 1 in 
+the adaptive strategy or 1,10, 100 in the fixed strategy.

+Other steganalysers than the ones used in this document will be
+examined for the sake of completeness. Finally, the
+systematic replacement of all the LSBs of edges by binary digits provided
+by the BBS generator will be investigated, and the consequences of such a 
+replacement, in terms of security, will be discussed.
+Furthermore, we plan to investigate information hiding on other models, such as high frequency for JPEG encoding.
