-The STABYLO algorithm, whose acronym means STeganography
-with cAnny, Bbs, binarY embedding at LOw cost, has been introduced
+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 the well known
-Highly Undetectable steGO (HUGO) steganographic scheme.
+somewhat smaller, security than well-known
+steganographic schemes
+HUGO, WOW, and UNIWARD.
This edge-based steganographic approach embeds a Canny
-detection filter, the Blum-Blum-Shub cryptographically secure
-pseudorandom number generator, together with Syndrome-Treillis Codes
+detection filter, the secure Blum-Blum-Shub cryptosystem
+with its pseudorandom number generator,
+together with Syndrome-Trellis Codes
for minimizing distortion.
-After having introduced with details the proposed method,
-we have evaluated it through noise measures (namely, the PSNR, PSNR-HVS-M,
-BIQI, and weighted PSNR) and using well established steganalysers.
+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. We will try
-to take into account the least significant bits too during all the
-stages of the algorithm, hoping by doing so to be closer to the HUGO scores against
-steganalyzers. Other steganalyzers than the ones used in this document will be
+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.
